Character LCD Modules TV, plasma TV display principle display principle


For LCD TV works, you must first understand what a special liquid crystal material. Liquid crystal is a regular arrangement of the organic compound, which is a range between the solid and liquid substances is generally used at present the most suitable for the manufacture of the molecular arrangement of the nematic liquid crystal displays fine columnar crystal. The important characteristic of liquid crystal in different directions different from the light transmission. The liquid crystal itself does not emit light, LCD TV backlight (backlight) principle, the use as a backlight source lamp, columnar liquid crystal molecules using different transmission characteristics of different directions, the liquid crystal molecules by changing the electric field around the liquid crystal molecules are arranged leaving a difference , thus changing the light through, similar to that for the backlight through a door opened, in order to control the light projected by simply changing the voltage value to stimulate the LCD can control the final appearance of the light intensity and color, and then control the screen display results. Liquid crystal display device complex structure for plasma devices. LCD panel mainly by two sodium-glass sandwich a polarizing plate, a liquid crystal layer and color considered a laminated sheet having a light formed. LCD screen coating fear alkaline solution or chemical solution wipe. lcd modules
Popularity of LCD TVs is much faster than plasma TVs, this is not due to the technical characteristics of the liquid crystal on the overall leader, is due more to the lack of plasma. In the application of resolution and screen size LCD TVs mainstream comprehensive beyond, far higher than the plasma relative to other advantages of LCD TVs. Currently 40 inches below the flat-panel TV products using LCD technology, but also in the large size LCD and plasma have been able to have equal shares. Through years of technological advances in uniformity, viewing angle, response time and even the color performance LCD unit has been demonstrated by the trend to catch up with the plasma. Therefore, the current production of LCD TVs better than plasma products. graphic lcd display module
