ViewSonic launches Innovative DCR technology Enhance Contrast Ratio up to 4000:1

ViewSonic Corp., a leading global provider of visual display products, today launched innovative dynamic contrast ration (DCR) technology, which enhances the contrast ratio of an LCD up to 4000:1. DCR technology automatically detects the image signal and intelligently controls the brightness of the backlight to enhance colour quality in a dark and bright environment. DCR technology is able to automatically adjust gray level and enhance gray level performance range. When there is a need to display a dark image, DCR technology will underpower the backlight lamp, but will proportionately amplify the transmission through the LCD panel. This gives the benefit of realising the potential static contrast ratio of the LCD panel in dark scenes. The primary advantage of DCR technology is to intelligently control LCD panel backlight. When the image is watched in a dark room, the drawback is that if a dark scene does contain small areas of superbright light, they may be sacrificed and blown out. By intelligently modulating the backlights, the user is able to experience lower black levels while watching darker movies or video games. This can help provide for a better user experience, and overall front of screen performance. The second advantage of DCR technology is power saving. Owing to DCR being able to automatically detect image source then to adjust LCD panel back light, the back light power consumption will differ from back light usage. Compared to convention LCDs, which backlight is always on, the voltage of LCDs with DCR technology is flexible based on the contrast ratio. The latest DCR technology can enrich image scale level and provide end-users the best color performance when seeing video or gaming. Also, for professional users, DCR technology can provide the real image performance quality for graphic designer and multimedia editing.Contrast Ratio Comparison:
