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.
Part of the Electronics glossary: LCD TV is a television display technology based on a liquid crystal display. LCD TVs consume much less power than plasma displays because they work on the principle of blocking light rather than emitting it. An LCD display uses either a passive matrix or an active matrix display grid. The active matrix LCD is also known as a thin film transistor (TFT) display. The passive matrix LCD has a grid of conductors with pixels located at each intersection in the grid.
