Yantai LCD splicing screen manufacturers offer 46-inch 55-inch LCD splicing screen, parameters, programs, pictures, HD, highlight, Model Contact: Mr. Liu 18688994974 with LED backlight for the LCD splicing, the main purpose is to enhance the quality, particularly is the color saturation, LED backlight display technology can be made wide enough color gamut, make up color LCD device displays the insufficient number of defects, so that it can meet or exceed Adobe RGB and NTSC color standard requirements, you can achieve NTSC ratio 100 %, of which Sony introduced the use of LED backlit LCD TV panels, with particular emphasis on the performance of red and dark green, to show the way more realistic than ever color. And because the LED flat light source characteristics, the LED backlight can achieve not comparable CCFL subregional color and hue adjustment function, enabling more accurate color reproduction, publishing and graphic plane to accommodate the needs of design work, the screen dynamic adjustment can be made in different screen display, brightness and contrast can be dynamically modified to achieve better picture quality. Since conventional LCD display devices CCFL (Cold Cathode Fluorescent Lamps, cold cathode fluorescent lamp) backlight technology and products some deficiencies, such as narrow color gamut, low energy efficiency of their high power consumption and short life expectancy, etc., so people have been looking for with its alternative technologies and products, and in the process, LED backlight technology products will be incorporated into the people's choice category. Principle point of view from the light, the LED is made of thin layers of doped semiconductor material, a layer with an excess of electrons, is the lack of electrons to form another layer of positively charged "holes", the work of the current passed, electrons and holes combined with each other places the excess energy in the form of optical radiation is released, LED is based on this principle to achieve electro-optical conversion, but also according to the different physical properties of semiconductor materials, LED can emit from ultraviolet to infrared Different spectra of different colors of light, especially white light LED technical problems can not be resolved for the application of LED in the display area and laid a fundamental basis.

LCD splicing products appear, so large-screen display market situation has undergone great changes. LCD products to have high-definition, wide viewing angle, high brightness, long life and other advantages, quickly recognized and accepted by many users. Within a few years, LCD products to occupy up to one fifth of the market share, but due to the LCD splicing products in the splicing process can not be avoided splicing gap, resulting in the popularization process encountered a difficult to break through the bottleneck, therefore, it has been predicted that, once opened LCD splicing seamless door display area will be fully into the LCD era.
