Products LCD With inherent advantages: ultra-thin thickness, no radiation, no flicker, and quickly became a hot display market, occupy a considerable market share. LCD technology by introducing its own characteristics and analysis of breakthroughs in technology and cost LCD recently achieved, allowing the majority of users on the LCD display walls have a certain understanding, close to the demand in the purchase of large screen LCD display wall, lower costs . Performance parameters LCD wall imaging modalities decided it includes: complete right angle, CRT monitor so-called geometric distortion phenomenon does not exist, no cRT display complex electron gun structure, can do very little volume, power consumption is very low, zero radiation and not blinking. These advantages make the LCD gained popularity in the fastest time, but these advantages are also all areas of expertise on the user wants to use, but on some technical indicators, LCD monitors worse than CRT monitors, such as response time, richness of color, these shortcomings but also makes professional users between LCD and CRT display is difficult to make a choice. Here we wish to display on the LCD monitor several major performance indicators compare with CRT monitors to see in the end what makes the difference in the choice of professional users on the LCD monitor produces hesitation. Response time for this indicator can be understood as the input image signal of the reaction. Is at the same point above the panel, from black to white and white becomes the sum of the time from black. Use and maintenance of information exchange and sharing can be achieved between the various systems through a combination of network servers through an external screen controller. Computer networks and other high-resolution digital and analog signals on the big screen in an open window; can achieve multi-channel video signals and multi-channel RGB signal through an external screen controller combination to switch the display anywhere on the big screen; big screen system uses a combination of TMC2109 external screen controller makes the system complete interface, powerful display. The entire system provides four video interfaces, two RGB interface; through any computer on the network control computer license can operate a large screen, and call each other to achieve control of the image. By controlling the computer control, can any one signal for each channel can be switched freely. According to user needs to develop common display modes, simple and flexible user interface; and support for multi-user operation, and set permissions for users.
