DESCRIPTION
Television today has become an inseparable part of our lives. An average human being
watches around 3-5 hours of television every day. Television is no more a luxury but a
necessity.
With growing families and limited television sets in a house, the demand for
simultaneously watching different TV programs has gone up considerably. An existing
way to resolve this problem is by displaying many images in separate regions on the
same display device, known as the Picture in Picture (PIP) feature. However, this
technology has its limitations. PIP is often used to watch one program while waiting for
another to start, or advertisements to finish. The PIP feature reduces the picture
proportionally, which has a disadvantageous influence on the viewing effect. Not only
that, usually televisions with PIP feature have only one audio output enabling the viewer
to listen to only one program i.e. the program on main display.
There have been attempts to bring a revolution in the televisions by way of different
display options and features such as LCD, LED, three dimensional (3D) televisions, PIP
etc. however, none of the features or displays have been able to successfully resolve the
issue presented above.
There has always been a desire to be able to feel the world around and it extends to the
TV viewing experience. With the advancement in technology and availability of 3D
content, this aspiration has increased the viewership not only amongst kids but also to
the youngsters and the elderly. The biggest factor for the acceptance of this new
technology is its ease of use. One need not buy or install any additional equipment and
can still readily watch two dimensional (2D) content using the same device and
experience the 3D effect. The present invention will address this concern by offering the
ability to switch between 2D and 3D viewing with merely a click of a button on the
remote control.
The biggest advancement of the 21st century is the mobile technology. Its application
along with yet another big technological breakthrough, the World Wide Web, has
touched millions of people. This technical amalgamation of Internet and mobile has
emerged unparallel growth for creating user friendly, graphical interfaces for end user
interaction. The present invention is fueled with one such super advanced operating
system called Android. The users of this invention will be able to use all supported apps
including web browsers, email and collaboration tools, fun and game activities, learning
tutorials, just as they would use on any other Android device.
SUMMARY
The present invention provides an entertainment device which has more than television
like features.
The invention is achieved by the use of passive 3D technology to provide cost effective,
high quality product. The invention primarily provides three functionalities:
1. Dual TV display - An embodiment of the present invention provides dual display and
uses the concept of polarization of light.
2. 3D TV - An embodiment of the present invention is capable of producing and
rendering 3D images for both 3D and 2D content without any additional enhancement
to the invention.
3. Android Device - The present invention is powered by Android OS and has both
compute and storage capabilities. Therefore, can be used like a computer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Refer to FIG.l a schematic drawing showing the cross section of the invention. Here, an
embodiment according to the present invention is revealed. The figure comprises of
multiple layers with varied functionality. Layer 1 (LI) consists of the LED lit panel which
produces the pure white light. Layer 2 (L2) is a polarized panel consisting of electrodes.
The white light after being evenly spread is passed through these electrodes. Thereafter,
the current flowing between the electrodes manages the luminosity and intensity of
colors. Based on the magnitude of the current, the liquid crystals (L5, L6 and L7) placed
between the electrodes, filters the light resulting in the formation of color stream. Thus,
the white light that originated from the LED panel, travels through the electrodes and is
received as colored stream on the next layer called polarized sheet (L3). L3 consists of a
polarizing material that polarizes the light so that it can be used for 3D/dual display.
Layer 4 (L4) is the Film Patterned Retarder (FPR) that sets the circular polarization in
place. Thereafter, the circular polarized light travels from the device to the spectacles
made up of distinct polarized sheets for the left and right eye (L8 and L9. The spectacles
are light weight and equipped to receive only the intended video frames, encapsulated
within polarized light.
Refer to FIG.2 an embodiment of the present invention is revealed showing circular
polarization of light received through the polarized filter used on spectacles. PI
represents a blend of two polarized lights, illustrated with red and blue colors. It shows,
how only the distinct circular polarized light, can penetrate through the polarized sheet,
P2. Streams of red and blue polarized light (coloring for the purpose of illustration only)
when exposed to P2 allows only blue light to penetrate and turns opaque to the red
light. The vice versa effect happens when a different polarizer sheet is used that allows
only red light to go through, thereby, ensuring both left and right eye receive the
intended light.
Refer to FIG. 3. an embodiment of the present invention is revealed showing circular
polarized light, E2, leaving the television,El, and traveling all the way to special
polarized spectacles, E3. E3 is comprised of polarized film capable of filtering E2 and
receive only the intended frameset and turning opaque for the other stream. The end
result is the left eye receives one set of images and the right eye receives another. The
human brain then combines both perspectives to form a 3D image.
FIG. 4 is a schematic drawing showing a closer look at the formation of 3D images using
the passive 3D technology. A2, the spectacles with polarized film is able to filter Al, the
polarized light and therefore receives the intended frameset and turns opaque for the
other stream. The left eye ends up receiving one set of images and the right eye
another set of images. Both when combined by the human brain turn 3D.
Refer to FIG.5 an embodiment of the present invention is revealed. FIG. 5 shows circular
polarized light B2 and B3 traveling to two viewers, wearing different set of polarized
spectacles, Bl and B4. Here, both the left and right eye of B4 receive frames from video
source 1 broadcasted by the polarized light B3 and turns opaque to Video source 2.
Video Source 2 is broadcasted by distinct circular polarized light, B2 which is received by
Bl. Leveraging the existing form factor and design of the television, B5, this invention is
designed to accept input from two alternative video sources (using USB, AV, Cable TV)
and is designed to broadcast framesets for both videos simultaneously.
FIG. 6 is a schematic drawing showing a closer look at the formation of dual display
simultaneously. Here two distinct set of eyes CI and C2 can watch two separate videos
at the same time using Passive polarization technique with the help of Polarized
spectacles C3 and C4. C3 and C4 are capable of filtering the circular polarized light C5
and C6, so that CI and C2 receive only one set of video frames. Spectacle C3 uses the
same polarized filter for both its left and right eye. This ensures circular polarized light
C5 reaches both eyes on CI. Similarly, distinct polarized filter is used on spectacles C4.
Thereby this allows only C6 to reach both eyes on C2.
Refer to FIG. 7, a schematic drawing showing the present invention powered by Android
OS is revealed. FIG. 7 is an illustrative snapshot view of the Android user interface, Dl.
I The present invention *is-equipped with high end compute capability and additional
storage which enables this device to be used as a wall hanging computer. For the ease
of navigation, the consumer can use the remote control device, D2 or attach a wireless
keyboard, D3. Dl is equipped with Ethernet port (not shown in the figure) along with
the provision for WIFI connectivity, to allow data exchange over the Internet. Thus, the
present invention is an Internet ready device with no restrictions on the type of
applications to be used. One can use browser, email - collaboration tools and apps
designed to be used on any other Android device. The logos used in the figure 7 are
only for illustration purposes and the applicant does not claim any IP rights over them.
