A matrix of thin-film transistors supplies voltage to liquid-crystal-filled cells sandwiched between two sheets of glass. Whether spread across a flat-panel screen or placed in the heart of a projector, all LCD displays come from the same technological background. You can also see the black ribs which separate each. Each pixel cell is essentially an individual microscopic florescent light bulb, receiving instruction from lcd tv 32 software contained on the rear electrostatic silicon board. This light illuminates the proper balance of red, green, or blue phosphors contained in each cell to display the proper color sequence from the light. Plasma flat screen technology consists of hundreds of thousands of individual pixel cells, which allow electric pulses to excite rare natural gases-usually xenon and neon-causing them to glow and produce light.
