Feasibility study on daylight-adaptable high-intensity backlight for TFT-LCDs harmlessly to human eyes

If TFT-LCDs are used in controllers, each with a picture monitor, are operated together with PCs under the direct sunbeam, or if smartphones and car navigators are mostly used under sunshine in a daily life, such displays would be strongly requested at brighter illuminance in outdoor-use under the strong sunbeam. We newly apply to the direct drive assembly of backlight to lighting for the rear of TFT-LCD by use of the high-intensity daylight-colored organic LED plate. Since the daylight-colored organic LED module is made of organic LED plate of two-dimensional lighting beam in rectangular shape. Its lighting strength is easily controllable with software, in three steps, low (indoor-use), medium (cloudy, outdoor-use), and high (sunshiny, under shadow of evergreen trees, outdoor-use), so as to be harmless to the human eyes.
