Liquid Crystal Display ﹝ Chinese LCD 1999 acronym for the main tenets of liquid crystal molecules to stimulate Electricity generated point, line, surface back with a picture lamp. Structural LCD Panel is made up of four components buy into: 1, backlight group ﹝ lamp ﹞ Backlight groups: general commonly known as Lamp group, after the cathode-ray phototherapy way into the lightguide plate, a total reflection of the light source into the lightguide plate proliferation point of the proliferation of film will be light through various angles to the spread everywhere, at this time there are about 40 ~ 50% of the light from the light module will be disclosed by the positive, not the proliferation of light left by the bottom of the reflective plate once again into the light module to the current technology can be 85% to 90% into the light source is derived from positive. 2, polarizing group Will the backlight group cluttered with a single ray of light direction CRT function much like the bias coil. 3, glass substrates and thin film crystal ﹝ TFT liquid crystal molecules group ﹞ In early <first generation to the 3rd generation> most of this technology for the mass production of the most difficult to break through, the reasons for thin materials for the substrate itself, has several internal LCD elements of the 1 million high-precision technology, coupled with its size without small, slightly cutting will not have an adverse carefully, it yields has been low until recently 3.5 ~ 4 generation production line technology, the relative cost to be reduced, the principles of liquid crystal molecules to produce electricity through a backlight because暗影, products of a point, a point of a line to form a picture. 4, a color filter Group The two-tone color LCD molecular electric current can change the electric field strength to change, as the decision to control color in the three-color filter body, through different filters have different color gamut, and further through the RGB blend reach 1.6 million pigment .
