[0041] FIG. 3A illustrates construction and working of the electrically controlled thin film display using an exemplary scenario, according to one embodiment of the invention. Construction of the display unit 205 includes a transparent piezoelectric material 303 sandwiched between two conducting semi-transparent conductive layers. The two conducting semi-transparent conductive layers includes a top layer 305a and a bottom layer 305b. In some example embodiments, the transparent piezoelectric material may be of a fixed refractive index and varying thickness. In some example embodiments, the two conducting semi-transparent conductive layers may be of a fixed refractive index and a fixed thickness. In some example embodiments, initial thickness of the piezoelectric material 303 and the fixed thickness of the two conducting semi-transparent conductive layers (305a and 305b) maybe calculated using their respective refractive indices. The initial thickness of the piezoelectric material 303 may be further varied during enablement of the electrically controlled thin film display.

[0042] The construction of the electrically controlled thin film display as illustrated in FIG. 3A involves exposure of layer 305a to one or more beam of incident light 301. A variable power source 307 is applied between the two conducting semi-transparent conductive layers namely the top layer 305a and the bottom layer 305b.
[0043] The electrically controlled thin film display is enabled by a thin film interference phenomenon. Further, the thin film interference is based on a process which involves the one or more beam of incident light 301 to pass through an interface between top surface and bottom surface of the top layer 305a followed by the interface between the top surface and the bottom of the piezoelectric material 303 and finally the interface between the top surface and bottom surface of the bottom layer 305b. The one or more beam of incident light 301 when passed through the above-mentioned interfaces of different refractive indices produces selective wavelengths thereby producing one or more pixel in the form of one or more beam of reflected light 309 on the electrically controlled thin film display.
[0044] In some example embodiments, the production of selective wavelengths is achieved by evaluating the required change in the thickness or volume of the piezoelectric material 303 based on the pixel information (same as the required color). Based on this pixel information, the corresponding magnitude of electric force that is needed to obtain the required variation in the thickness is evaluated and the variable power source 307 then supplies the specific magnitude of electric force to the top layer 305a and the bottom layer 305b to control the thickness or volume of the piezoelectric material 303. For example, the thickness of the piezoelectric material is “t1” and to achieve a certain change in the thickness or volume of the piezoelectric material say “dt”. The specific magnitude of electric force supplied by the variable voltage source 307 results in a new thickness of the piezoelectric material “t1+dt”.
[0045] In some example embodiments, the phenomenon of thin film interference may involve occurrence constructive interference. For example, considering one of the two conducting semi-transparent conductive layer say the top layer 305a, if the difference in the wavelength reflected by top surface of the top layer and the wavelength reflected by bottom surface of the top layer is an integer number of a whole wavelength, then it produces constructive interference causing an increase in the intensity of the one or more beam of reflected light 309.
[0046] In some example embodiments, the phenomenon of thin film interference may involve occurrence destructive interference. For example, considering one of the two conducting semi-transparent conductive layer say the top layer 305a, if the difference in the wavelength reflected by top surface of the top layer and the wavelength reflected by bottom surface of the top layer is an integer number of a whole wavelength plus half wavelength, then it produces destructive interference causing a decrease in the intensity of the one or more beam of reflected light 309.
[0047] In some example embodiments, the wavelength reflected from the bottom surface of a layer may add wavelength since the one or more beam of incident light travels an extra distance, this additional wavelength changes based on the thickness of the layer and hence thickness of the layer (thin film) affects the one or more pixel to be produced on the electrically controlled thin film display. Construction and working of the electrically controlled thin film display based on another example scenario may be explained in the FIG. 3B.
[0048] FIG. 3B illustrates construction and working of the electrically controlled thin film display based on a transparent liquid, using an exemplary scenario, according to one embodiment of the invention. Construction of the display unit 205 includes a transparent liquid 303 sandwiched between two conducting semi-transparent conductive layers. sandwiched between two conducting semi-transparent conductive layers. The two conducting semi-transparent conductive layers includes a top layer 305a and a bottom layer 305b. In some example embodiments, the transparent liquid 304 may be of a fixed refractive index. In some example embodiments, the two conducting semi-transparent conductive layers may be of a fixed refractive index and a fixed thickness. The transparent liquid 303 may be attached to a liquid reservoir 311.
[0049] The construction of the electrically controlled thin film display as illustrated in FIG. 3B involves exposure of layer 305a to one or more beam of incident light 301. A variable power source 307 is applied between the two conducting semi-transparent conductive layers namely the top layer 305a and the bottom layer 305b.
[0050] The electrically controlled thin film display is enabled by a thin film interference phenomenon. Further, the thin film interference is based on a process which involves the one or more beam of incident light 301 to pass through an interface between top surface and bottom surface of the top layer 305a followed by the interface between the top surface and the bottom of the transparent liquid 304 and finally the interface between the top surface and bottom surface of the bottom layer 305b. The one or more beam of incident light 301 when passed through the above-mentioned interfaces of different refractive indices produces selective wavelengths thereby producing one or more pixel in the form of one or more beam of reflected light 309 on the electrically controlled thin film display.
[0051] In some example embodiments, the enablement of production of selective wavelengths is achieved by evaluating the required change in the volume of the transparent liquid 304 based on pixel information. Based on this pixel information, the corresponding magnitude of electric force that is needed to obtain the required variation in the volume of the transparent liquid 304 is evaluated and the variable power source 307 then supplies the specific magnitude of electric force to the top layer 305a and the bottom layer 305b to control the volume of the transparent liquid 304. The increase and decrease in the volume of the transparent liquid 304 is aided by the liquid reservoir 311 which supports the flow in and flow out of the transparent liquid 304 depending on the pixel information to be produced on the electrically controlled thin film display.
[0052] Fig 3C illustrates an example for enabling the electrically controlled thin film display. Consider a television system 221 with a resolution of 1920 pixels horizontally across the screen and 1080 pixels vertically. These pixels serve as a foundation of how a TV image is put together, along with certain other characteristics like brightness, contrast, color, tint and the other like. Consider an image 223 displayed on the television system 221, this image 223 is composed of 2,0,73,600 pixels, that indicates an array of display units (205) in the order of 1920 pixels horizontally and 1080 pixels vertically is used to form the this image 223. In some example embodiemnts, each of the display units (205) may individually be configured to form various characteristics like shape, texture etc. , for example, forming an image of a boat as shown in the FIG. 3C.
[0053] FIG. 4 illustrates a flow chart for enabling the electrically controlled thin film display, according to one embodiment of the invention. The flowchart shall be understood that each block of the flow chart of the method may be realized by various components, such as circuitry, firmware, processor, and/or other devices associated with execution of a software.
