Abstract: PURPOSE: A system and a method for correcting brightness distortion are provided to meet the size of the completed LCD(Liquid Crystal Display) panel for checking and correct exactly the brightness distortion. CONSTITUTION: A backlight(14) is a reference light emitting device which is used in order to correct the brightness distortion when checking badness of the LCD panel. A diffusion filter(12) is installed to an upper portion of the backlight(14) and controls the brightness of the backlight(14) uniformly. An image acquisition device(10) obtains image and brightness data of the backlight(14) and the completed checking LCD. A light intensity meter measures the brightness of a diffusion filter surface. An image processing unit(15) stores variation obtained from the brightness data measured by the light intensity meter and image and brightness data of the diffusion filter surface and thereafter applies it to the brightness data of the completed checking LCD, thereby correcting the brightness distortion.

Abstract: PURPOSE: A system for adjusting convergence of a projection display is provided to reduce a failure rate and improve the productivity by automatically adjusting the convergence of a liquid crystal panel. CONSTITUTION: A pattern storing unit(40) stored data of test patterns. A liquid crystal driving unit(100) displays the pattern data on liquid crystal display panels(1,2,3). An optical engine unit projects images displayed on the liquid crystal display panels to a screen. A plurality of photographing units(10) photograph the test pattern images projected to the screen. An image processing unit(30) processes the test pattern images photographed by the plurality of photographing units. A control unit(60) detects an error from the output image of the image processing unit for outputting an adjusting signal. A plurality of driving units(81,82,83) adjust positions of the liquid crystal panels according to the adjusting signal. A bond injecting unit(120) injects a bond for fixing the liquid crystal panel.
