LCD large screen display wall technology features

LCD large screen display wall advantages: ultra-thin thickness , no radiation , no flicker , and quickly became a hot display market , the big screen market occupied a considerable market share. By introducing large-screen LCD display wall itself, technical characteristics and analysis of large-screen LCD splicing technology and cost in recent breakthroughs in the hope that the majority of users on the LCD large screen display wall have a certain understanding , in the purchase of large-screen LCD when the wall close to the demand for cost reduction .
LCD large screen display wall imaging modality determines that it includes: a complete right angle , there is no so-called CRT monitors geometric distortion , no CRT monitor electron gun structure of the complex , you can do a small volume , power consumption is very low, zero radiation and not blinking . These advantages make the LCD in the fastest time gained popularity, and these advantages are all areas of expertise on the user wants to use , but in some technical indicators , LCD monitors worse than CRT monitors , such as response time, richness of color , these shortcomings but also makes professional users between the LCD and CRT display is difficult to make a choice. Here we wish to place the LCD monitor in several key performance indicators on the display compared with CRT monitors to see what makes the difference in the end professional users the choice of the LCD display produces hesitation.

LCD large screen display wall : Response time
For this indicator , can be understood as the reaction speed of the input image signal . Is the same point in the panel above , from black to white and white to black from the sum of the time . If the index is too long , then quickly switch the image or video playback will produce "smear " phenomenon, affecting. For CRT monitors , the response time is generally about 1ms , while for LCD monitors in terms of early LCD is about 80ms response time is too long is the LCD using the most headaches . However, this problem has been basically solved , and now the latest LCD response time of 25ms or so, although there is a certain gap compared with the CRT , when watching a DVD , you need to display 33 pictures per second , that the response time of less than 30ms to (30ms = 1000/33). As for the play action game is concerned, such as demanding QUAKEIII, if you want to do completely without "smear " , the screen should display speed 60 frames per second or more, that the response time of less than 16.6ms to (16.6ms = 1000 / 60 ) . Currently on the market line display manufacturers LG, BenQ and Samsung have launched a response time of 16ms LCD display products , but for most of the major applications for the Internet, office , data processing and image data for users who appreciate , 25ms response time of the LCD products have been fully able to meet their needs. Therefore, the major display manufacturers are also providing support to users 16ms response time LCD products and support 25ms response time LCD products .
LCD large screen display wall : number of colors
Number of colors , refers to the monitor can display the number of colors , the higher the index , the picture is more abundant . In addition to the response time outside , another effect professional users to buy the LCD monitor is probably an important reason for the number of colors ,lcd module and now basically CRT monitor can display 32-bit color , that 232 kinds of colors, 4294967296 . Early , LCD can only achieve 16-bit color , approximately sixty-five thousand kinds , while recent period , with advances in technology have LCD can display up to about 24 -bit color , about sixteen million kinds . If just from the indicators , LCD is still some distance away from the CRT , but actually speaking, sixteen million kinds of color can also meet the needs of most applications .
In the enhanced color performance technology research and development , LG's Kofi technology (ColoriFic) unique, Kofi technology (ColoriFic) by adjusting the applied voltage interval for the color change is more consistent and separation of the signal transmission , the signal enters the liquid crystal after the display , continuing with the process, the horizontal signal and the vertical signal are clearly separated to form a double signal channel .
After being separated processed signal is transmitted to the liquid crystal panel is more accurate color purity and clarity so effectively improved. In addition, Kofi technology (ColoriFic) built a variety of colors ,color lcd display module brightness, contrast and sharpness of the display modes , such as combinations of Office, Internet , movies , etc., for the user to easily select , and also supports a variety of printing devices WYSIWYG true color output.
