Abstract
To enable application to full moving images, the response time of liquid crystal displays (LCDs) must be improved. In this paper, we will discuss our results of improving the response time using the blink backlight system. When the display image changes from black to white, the lamp turns on after the rise of the LCD response. On the other hand, when the display image changes from white to black, the lamp turns off before the LCD response falls. The total response time of the super thin film transistor (TFT)-LCD was improved from 25 ms to 8 ms, which corresponded to the lamp response time. Moreover, the response time was dependent on the fluorescence wavelength of the lamp material. The blue fluorescent lamp (CFL) material has the fastest response time, 2 ms. If the response time of green and red fluorescent materials can be improved similarly to the blue one, it will be possible to obtain a moving picture quality comparable to that of a cathode-ray tube.
