The set-up. Housed between two sheets of glass is the technology that allows flat screen TVs to work. Depending on the type of flat screen TV, the process can differ slightly. In a plasma TVs are cells that contain the gases xenon and neon as well as electrodes.There are two types of electrodes, display and address, that are arranged in a grid-like pattern on either side of the cells.n a LCD flat screen TV, tiny liquid-crystal-filled cells are between the glass sheets. A bright white light is located behind the cells and illuminates them to create the picture.
That's an opportunity for differential brightness across the screen. A curved screen, with the proper radius, allows for all the pixels to be viewed straight on. However, the big deal is when the TV is viewed by someone off to the side. Perhaps the second person on the couch sits to the right of the sweet spot, so that their eyes are straight-on to the rightmost pixels of the screen, and about 33 degrees offset from the leftmost pixels of the screen.
