What are the different types of Flat-Screens, and what is the difference between them?
1.light-emitting diodes (LEDs) - light-emitting diodes that can be turned on and off 2.liquid-crystal displays (LCDs) - polarization of the liquid crystals in the middle panel plasma panels - voltages on the grids to energize gases Similarities: 1.All use a two-dimensional grid to address individual light-emitting 2.The two outside plates each contain perpendicular parallel grids of wires . Sending electrical signals to a wire in each grid, generates electrical field at the Intersection of two wires, can control the corresponding element in the middle plate.
