DESC:TECHNICAL FIELD
[0001] The present subject matter relates generally to a display device. More particularly but not exclusively the present subject matter relates to cooling of the display device.
BACKGROUND
[0002] Nowadays, many electronic devices, such as smart phones, tablet computers, or laptops, have adopted touch display devices as input and output devices of the above-mentioned electronic devices. Generally, the touch display device is formed by combining two boards, one of which is a touch-sensitive panel, and the other is a display panel. The touch panel is attached to the display panel through an adhesive layer, and the image of the display panel is presented to the user through the touch panel through the emitted light.
[0003] Particularly, in recent years the demand of the display device with integrated embedded touch-screen is constantly increased, this display device comprises multiple built-in elements, for the slim portable terminal device providing such as a smart phone, a tablet, a PC, and in an instrument panel of automobiles. The instrument panel is used to display relevant information about a device or the vehicle to an operator/user. When used in vehicles, the instrument cluster displays information like total distance travelled, vehicle speed, engine speed, fuel level, battery charge level, fuel efficiency, operational status of lamps on the vehicle, tyre pressure, and so on. In four-wheeled vehicle, the touch enabled displays are already available. However, in other automobiles, such as two-wheeled or three wheeled vehicle, having such touch enabled display is still a challenge for the manufacturers.

DETAILED DESCRIPTION

[0001] Generally, an instrument cluster, except in four wheelers, do not have touch enabled screen, specifically, a touch enabled screen with a bigger size, and brighter screen. The main concern with touch screen with bigger display screen is thermal management. Larger and brighter displays are more convenient and aesthetically appealing to the user. The bigger the touch enabled display, higher will be the heat generated and thus dissipating that heat is a challenging task, especially in a two-wheeled vehicle, where weight, space, and cost are the crucial parameters which is considered while manufacturing the two-wheeled vehicle.
[0002] In bigger size touch enabled display, excessive heat is generated due to multiple processors and PCB’s (Printed Circuit Board), which can dissipate heat up to 10 W and are the main source of heat generation, resulting in rise in temperature. In case of LED displays, heat generated has to be dissipated outside the instrument cluster to prevent damage and ensure longevity and durability of the LEDs used. With the increase in number of LEDs and peak brightness of the screen, more heat needs to be dissipated out of the instrument cluster. This rise in temperature is quite high and makes it impossible for a rider’s finger to interact with the touch enabled display. Rise in temperature can also impede the working of the display which is not at all desirable. Hence, it is ideal to maintain the display within prescribed temperature limit. Heat is also generated by other components of the instrument cluster including processors, communication modules, and also due to being exposed to the sunlight. Heat generated in these components may accumulate inside the instrument cluster increasing overall temperature of the instrument cluster. Hence, it is ideal to eliminate heat entrapment zones between different components/modules and enclosures of the instrument cluster and effectively dissipate heat away from these zones.
[0003] To overcome the above-mentioned problems, the touch enabled display can be provided with an active cooling. But the problem with this type of cooling is that it adds considerable weight and cost to the display and ultimately costs extra money to a consumer. Also, the surface contact area of the heat sinks provided in the instrument cluster with the heat producing part is less, which is unable to dissipate heat effectively. As compared to the system in four-wheeler, the system is placed in a closed environment and is not exposed to the outside environment directly. Also, since the four-wheeled vehicle is mostly provided with an air conditioner, exposed surface of the display also dissipates some heat in the external cooler environment, therefore the general available heat sinks are sufficient for heat dissipation and no additional external cooling mechanisms are required.
[0004] Also, if there is a gap between the touch sensitive panel and the display panel, a greenhouse gas type effect is generated, and more heat is produced. In addition to this, a top and a bottom enclosure are fastened together using multiple fasteners in some designs or bonded together permanently, for bigger screen multiple and bigger fasteners are needed, which increases the assembly time and cost. The multiple fasteners affect the aesthetics of the instrument cluster. The instrument cluster has additional capabilities which adds to more heat generation.
[0005] Thus, there is a need to overcome the above-mentioned problems and other problems of known art.
[0006] An objective of the present subject matter is to provide an improved cooling mechanism an instrument cluster of considerably bigger size as compared to conventional displays used in the automobiles. The present subject matter further aims to provide a compact display which is light-weight, low-cost, has reduced number of parts, and is aesthetically appealing.

However, the present invention is not limited to the present embodiments. The present subject matter is further described with reference to accompanying figures. It should be noted that the description and figures merely illustrate principles of the present subject matter. Various arrangements may be devised that, although not explicitly described or shown herein, encompass the principles of the present subject matter. Moreover, all statements herein reciting principles, aspects, and examples of the present subject matter, as well as specific examples thereof, are intended to encompass equivalents thereof.
[0001] Fig.1(a) exemplarily illustrates a top perspective view of a display device 100. Fig.1(b) exemplarily illustrates a back side view of display device. Fig.1(a) and Fig.1(b) shall be discussed together. In the present embodiment, the display 100 is placed in an instrument panel (not shown) of a two-wheeled vehicle (not shown). The display device 100 shows a numerous of information and allows the user to select from the options to use the features and to ride the vehicle accordingly. The display device 100 comprising of a display unit 102, a first cover 104, and a second cover 106. The first cover 104 accommodates the display unit 102. The second cover 106 is disposed on the first cover 104. The first cover 104 and the second cover 106 are configured to have one or more structural ribs 108 to provide structural strength and durability to the display device 100. The display unit 102 gives the visual display of information to the customer whereas a touch panel (not shown) of the display unit 102 gives improved touch performance and the non-scratch characteristics adding to its advantage. The present invention aim is to reduce the amount of heat generated in larger displays with increased number of components and with different IOT capabilities. The size of the display unit 102 lies in the range of 7- 14 inch.
[0002] However, in the present embodiment the size of the display unit 102 is 10.25 inch, which is considerably large as compared to the display units 102 used in the already existing two-wheeled vehicle (not shown). If there is a gap present between the display and the touch panel, a greenhouse gas type effect gets created, resulting in production of more heat. Such a large screen with gap can generate heat up to 10 W, resulting in rise in the temperature in the range of 75- 90 degree celsius. So, in order to avoid the above-mentioned situation, the display with the touch panel constituting the display unit 102 is optically bonded by means of adhesive/ sealant. In the best embodiment, LOCA (Liquid Optically Clear Adhesive) (not shown) is used to optically bond the display and the touch panel. The bonded display with the touch panel is left for cure so as to form the display unit 102 as a display sub-assembly. The application of LOCA reduces the internal reflections caused due to the gap between the display and the touch panel. In the best embodiment, the touch panel is a soda lime glass. The second cover includes one or more heat sink 110 integrated with the second cover 106 for passive cooling of the display device 100. The one or more heat sink 110 includes a display heatsink 110a, one or more heat pipe heat sink 110b, and one or more middle heat sink 110c. In an embodiment, a camera and an IR LED are integrated as a single component to enhance night vision with better focus view.
[0003] Fig.2 exemplarily illustrates an exploded perspective view of the display device 102. The first cover 104 is configured to accommodate one or more electronic components like one or more processor 112, one or more ports 114, and one or more antennas (not shown). In the present embodiment, the display device 100 has one processor 112 which carry out all the process of the display unit 102 and a single PCB 116 is used to mount both display unit 102 and the processor 112. The first cover 104 is disposed on the display unit 102. The first cover 104 is configured to accommodate one or more electronic components 112, 114 of the display device 100 for the functioning of the display device 100. Further, the second cover 106 is disposed on the first cover 104 to complete the assembly of the touch enabled display device 100. The second cover 106 is configured to be enmoulded with the one or more heat sink 110. The heat sink 110 is placed such that, it is thermally and physically in touch with the one or more electronic components (112, 116) and the display unit 102 to sink the heat. In the present embodiment, the one or more heat sink 110 and one or more fins 118 of the display heat sink 110a are made up of a metal, and the rest of the parts of the second cover 106 is made up of plastic. In the best embodiment, the metal is an aluminum metal.
[0004] The second cover 106 is configured with one or more cut outs (not shown) to accommodate the one or more fins 118 of the one or more display heat sink 110a. This reduces the weight of the second cover 106 and thus the overall weight of the display device 100. For the heat sink material, magnesium and copper can be used as it is comparatively less in weight and for receptive heat transfer, however the above-mentioned materials interfere with the signals of one or more reception system such as Bluetooth, NFC antennas, and the like. In the present embodiment, a dual-heatsink (two heat sinks) 110 design is used that removes the produced heat from a backside of the display unit 102. The backside of the display unit 102 is provided with one or more thermal pads 120, the thermal pad 120 is in direct contact with the display unit 102 to remove heat produced from the display unit 102. In another embodiment, the one or more thermal pads 120 can be placed on any surface or area where heat is produced, so as to remove the heat in the display device 100. The heat sink 110 optimally maintains the system within the hardware functional limit and almost eliminates the temperature raise that is caused while the instrument cluster (not shown) is functioning.
[0005] A back side of the second cover 106 is configured with a vent hole 122 and a vent plug 124 for exhausting gases accumulated in space between the first cover 104 and the second cover 106. The vent hole 122 prevents build-up of entrapped gases within the display device 100, thereby increasing service life. In an embodiment, the vent plug 124 is provided to close the vent hole 122. The vent plug 124 prevents entry of dust and water into the display device 100. The vent plug 124 may be made of resin, silicone or rubber material. Additionally, the vent plug 124 may include minute perforations for gases to escape from the hollow space. The processor 112 mounted on the PCB (Printed Circuit Board) 116 is provided with one or more processor thermal pads 120 disposed on the processor 112 for dissipating heat generated by the processor 112. The second cover 106 includes a port opening 128 to receive the one or more ports 114 to interface with the PCB 116 for electrically and communicatively connecting the display device 100 to external components. The second cover 106 includes one or more mounting bushes 130 to mount the display device 100 on the vehicle.
[0006] The heatsink 110 does nothing when the display device 100 is in turned-off condition. The heat from the display unit 102 to the aluminium heat sink 110 disposed in the second cover 106 is negligible as it is very low. But when the display device 100 is turned-on, it heats up the display unit 102 both in top and bottom direction. The heat from the display unit 102 comes from a LED backlight (not shown) which is located at backside of the display unit 102 which is considered as a major heat source. When the display device 100 is turned-on, heat from the heat source is directly dissipated by the aluminium heat sink 110 which touches the rear side of the display unit 102. By dissipating heat from behind, the heat transfer in the top direction is reduced and the touch screen temperature is maintained at the same condition as when the touch enabled display 100 was in turned-off condition. Apart from this, the touch panel is secondarily protected by an optional IR film (not shown) that restricts Infra-red rays which builds up heat when the vehicle is parked in direct sunlight.
[0007] In an embodiment, an active cooling system (not shown) is employed by either using a fan (not shown) or a liquid cooling system (not shown). But by implementing the active cooling system, the vehicle range is reduced as the power for cooling is also taken from the main battery (not shown) in case of an electric vehicle. However, the active cooling system is a better option for a vehicle with an internal combustion engine (not shown). The active cooling system can be one of a Peltier module coupled with the cooling fan (not shown), or a Copper heat pipe coupled with the cooling fan (not shown), or a liquid cooling circuit with a radiator setup (not shown), or a liquid cooling circuit from a vehicle main radiator (not shown).
[0008] Fig.3 exemplarily illustrates a side view of the display device 100, showing the first cover 104 and the second cover 106. The display unit 102 having the display and the soda lime glass is optically bonded together to form the display sub-assembly 102. The rear side of the display unit 102 shows a FPC cable (not shown) connection between the components of the one or more PCB 116 (shown in fig.2) accommodated in the first cover 104 with the display unit 102. A LED backlight FPC cable (not shown) connects the PCB 116 to the display unit 102. An LED backlight (not shown) creates a light that allow the display unit 102 to create the required image. There are multiple ways in which the LED backlights (not shown) can be arranged and different type of arrangement has different effect on picture quality of the display. The first cover 104 is a plastic part, which helps in reducing the weight of the display device 100.
[0009] The display unit 102 formed as a sub assembly includes a glass projection (not shown) across its periphery. LOCA is applied all over the glass projection and this display unit 102 sub-assembly is glued with the first cover 104 of the display device 100. The structure thus formed is mounted using a single fastener (not shown) which acts as an external clamp till the LOCA cures in between the display unit 102 and the plastic first cover 104. The first cover 104 along with the display unit 102 is attached with the second cover 106 to form the display device 100. The second cover 106 is configured to have a groove 132 filled with sealant at a periphery of the second cover 106. The first cover 104 includes a projection 134 at a periphery, the projection 134 is configured to be accommodated in the groove 132. The second cover 106 is pressed and force is applied on the first cover 104 to cure the sealing means to form the touch enabled display 100. In the known art, to connect these parts, one or more fasteners (not shown) were used but it adds to the weight of the device 100 and also was not aesthetically appealing.
[00010] Thus, in the present embodiment, the first cover 104 and the second cover 106 are glued to each other by means of the groove 132 and projection 134 design, which also reduce weight and thickness of the entire display device 100 and thus provides a compact packaged display device 100. The above-mentioned design can withstand high vibration. The sealing means (LOCA) has the capability of withstanding up to operating temperature 75-90°C. Apart from this, the first cover 104 and the second cover 106 are provided with one or more structural ribs 108 for structural rigidity and vibration resistant, thus holds the PCB 116 intact at its place. The first cover 104 and the second cover 106 prevent dust and water entry, sustain vibration, and provides structural rigidity. Use of LOCA for attaching the parts, reduces the number of parts, weight and limits the part with minimum possible dimensions.
[00011] Fig.4 exemplarily illustrates an exploded view of the parts disposed at the back side of the second cover 106. The back side of the second cover 106 includes one or more heat sinks 110 mounted on the second cover 106. The one or more heat sink 110 includes a display heatsink 110a, one or more heat pipe heat sink 110b, and one or more middle heat sink 110c. The display heat sink 110a is in direct contact with a display back plate 152 of the display unit 102 through one or more openings (not shown) in the first cover 104. The one or more fins 118 provided on the display heat sink 110a is made of metal and the one or more fins 118 are enmoulded with the second cover 106 which is a plastic part, to remove heat from the one or more electronic components 112, 114. In the present embodiment, the one or more fins 118 disposed on the display heat sink 110a provided at a left and at a right side of the display heat sink 110a. The middle heat sink 110c is provided on the middle part of the second cover 106 which extends towards the centre of the display unit 102 so as to be in direct contact with the one or more electronic components of the display device 100, through an opening 136 provided on the second cover 106, so as to dissipate the heat generated by the other electronic components 112, 114 of the display device 100.
[00012] The heat pipe heat sink 110b is provided on the display heat sink 110a. In the present embodiment, the heat pipe heat sink 110b includes two heat sinks and a heat pipe 138. The two heat sinks 110b are placed parallelly below the one or more fins 118 at both the left side and the right side of the display heat sink 110a. However, the number of heat sink in the heat sink heat pipe 110b can be increased based on the construction and heat dissipation requirement of the display device 100. The heat pipe 138 connected to the one or more heat pipe heat sink 110b is partially flushed in the display heatsink 110a.
[00013] Now the working principle of the heat pipe 138 will be explained. The heat pipe 138 used in the present invention is a copper tube filled with a cooling liquid. Both ends of the heat pipe 138 are sealed. The heat pipe 138 includes an evaporator length 140 at one sealed end of the copper tube and a condenser length 142 at the other sealed end of the copper tube. There are two compartments inside the copper tube. The evaporator length 140 is placed in close proximity of the electronic components dissipating heat. The heat is conducted through the copper tube and is received at evaporator length 140. The liquid filled in the copper tube near evaporator length 140 evaporates and form vapor using the conducted heat energy and it flows in a first compartment toward the other end of the tube, which is the condenser length 142. Here, the vapor condenses by the ambient air, as the condenser length 142 is either exposed to a cooling mechanism or an ambient environment. Then, the condensed liquid return through a second compartment towards the evaporator length 140 to continue the heat dissipation process. In the present embodiment, the heat pipe 138 is a copper pipe. However, any other suitable heat conducting metal can be employed. In the present embodiment, the heat pipe 138 is connected to two heat sink 110b to dissipate the heat. However, any other heat dissipating mechanism can be used in conjunction with the heat pipe 138.
[00014] Fig.5(a) exemplarily illustrates a rear and side view of the display device 100 as per the embodiment of the present invention. Fig.5(b) exemplarily illustrates an exploded view of the heat pipe heat sink 110b and the display heat sink 110a, and other parts are omitted for brevity. Fig.5(c) exemplarily illustrates a magnified side view of the display device 100 as per the embodiment of the present invention. Fig.5(a), Fig.5(b), and Fig.5(c) shall be discussed together. In the present invention, the heat pipe 138 is specifically employed to dissipate heat from the LED backlight placed on a front side upper periphery of the display unit 102, which is a major source of heat in the display device 100. So, the heat pipe 138 is disposed in very close proximity to the display unit 102 with the first cover 104 and is placed on the upper periphery of the second cover 106, touching the back upper periphery of the display unit 102 to enhance the heat dissipation. The copper tube used in the present invention is in the size of 8-10 mm. However, the dimension of the copper tube can vary based on the heat dissipation requirement. The size of the copper tube and the material of the tube enables easy bending of the tube, which further facilitates in forming any shape of the heat pipe 138 to accommodate in an existing space. In the present embodiment, the heat pipe 138 is a single part. However, the heat pipe 138 can be in two-part form or more. In the present embodiment, the heat pipe 138 is disposed onto the display heat sink 110a, substantially in a U-shaped, where both the legs of the U-shaped heat pipe 138 are connected with the two heat sink of the heat pipe heat sink 110b respectively.
[00015] The two ends of the U-shaped heat pipe 138 acts as condenser length 142 which is connected to the two heats sink of the heat pipe heat sink 110b respectively to condense the hot air and cool it, thus dissipating heat. The two ends of the heat pipe 138 get inserted in a heat sink opening 144 (shown in fig.4) in the two heat sink of the heat pipe heat sink 110b respectively to form physical contact between the heat pipe 138 and the heat sinks 110b respectively. The condenser length 142 extends till a stepped portion 146. After the stepped portion 146, the evaporator length 140 starts connecting the two ends of the heat pipe 138. In the present embodiment, the stepped portion 146 is provided such that a part of the heat pipe 138 can be flushed easily with the display heat sink 110a. In the present embodiment, the evaporator length 140 is flushed with the display heat sink 110a so that the evaporator part 140 is in direct contact with the display unit 102 through the display heat sink 110a. The display heat sink 110a is provided with a slot 148, partially in the shape of the U-shaped heat pipe 138 to allow it to pass through the slot 148 so as to make contact with the display unit 102. The condenser length 142 gets inserted in the heat sink of the heat pipe heat sink 110b as shown in fig.5(c) for dissipating the heat. One or more side walls 150 of the display heat sink 110a as shown in fig.4, have different height of walls 150 which acts as a locator to house the left and right side of heat sink of the heat pipe heat sink 110b. Many other improvements and modifications may be incorporated herein without deviating from the scope of the invention.
