Abstract: PURPOSE: A device and a method for compensating the driving of a scanner are provided to compensate the variation of the driving by controlling a data output point of a driving property after sensing the variation of the driving property. CONSTITUTION: A rotation sensing device outputs a sensing signal which senses the rotation of a scanner. When the scanner normally rotates according to the inputted scanner driving signal, a driving compensating unit(150) calculates time difference between the output estimating point of a reference sensing signal outputted from the rotation sensing device and the actual output point of the reference sensing signal by the actual rotation. The driving compensating unit controls the output point of the scanner driving signal based on the time difference.

An RGB(Red, Green, Blue) light source(108) emits RGB lights. A memory(102) stores a percent light intensity index according to RGB light sources in a lookup table type. The percent light intensity index by light source controls the entire brightness of an image by percent on the basis of the maximum brightness according to the entire brightness variation of the image. A light source output control unit(104) receives the percent light intensity index by light source from the memory and supplies a predetermined amount of a current to a light source driver(106) according to the brightness percent of the image. The light source driver drives each of the RGB light sources with the amount of the current supplied from the light source output control unit.

Abstract: A display system and a method for performing white balance adjustment are provided to control light sources individually to perform the white balance adjustment without the loss of gray levels. Currents, at which maximum light intensities of red, green, and blue light sources are output, are respectively measured when maximum gray level data are outputted for the red, green, and blue light sources(S304). A light source, which outputs the minimum light intensity among the red, green, and blue light sources, is set to a minimum light intensity output light source(S306). A light intensity ratio of the red, green, and blue light sources is set according to a predetermined target color temperature(S310). Application currents are determined correspondingly to the output light intensities of respective light sources, based on the light intensity ratio of the light sources and the minimum light intensity output light source(S314).
