We all know that CRT's works after the filament heating power, the cathode is excited, emitting electron flow, electron flow under high voltage with an internal metal layer acceleration, through the lens focused to form very fine electron beam, hit the screen , so that the light-emitting phosphors. The principle is completely different and CRT, LCD needs to come from behind the light source, when the beam through this layer of liquid crystal, theLCD module experience side by side or reverse the shape of irregular, so more like a liquid crystal gates, light penetration is selected, we can on the screen to see different shades, the patchwork of images.

Current mainstream thin-film transistor liquid crystal displays are LCD (TFTLCD), is the original and some liquid crystal display technology that extend it. TFT LCD for each pixel has a semiconductor switch, in order to achieve complete control of a single pixel, TFT liquid crystal material is sandwiched between layers of glass and color filter layer between the liquid crystal by changing the stimulation voltage can be control of the last occurrence of the light intensity and color.

Liquid crystal is transparent under normal circumstances, unless the applied voltage. Pressure, the part will change and become opaque. This LCD is usually very slow switching speed (will be described in detail later). In 1992, EMI announced the invention of a new liquid crystal display technology, ferroelectric liquid crystal FLCD (ferroelectricLCDs). Ferroelectric liquid crystal has the advantage of fast response, up to microseconds. And no need to change the voltage to maintain the current state, that is, more power, which for laptop, PDA and other portable equipment, is very meaningful. FLCD many advantages, but the lack of very few products on the market, because FLCD the vibration is very sensitive, very easy to damage the crystal, but it will certainly be improved.

Although the ferroelectric liquid crystal graphics LCD module is unknown, but it also has a large viewing angle, high contrast boxes, etc., on the mainstream market, the TFT will have a certain impact. FLCD response time? In the normal operating temperature, only 70us! Such a short time is almost ignored.
