Abstract
A RGB simultaneous correction-type device for display gamma correction is proposed, the device including an RGB test pattern output unit forming three division surfaces resulting from dividing a display into three surfaces around a center portion thereof and simultaneously outputting R, G, and B patterns to each of the division surfaces; a unit probe module having three probes disposed one by one at each of the division surfaces corresponding to the R, G, and B patterns; and a correction control unit analyzing each probe detection signal of the unit probe module to simultaneously perform gamma correction for R, G, and B values of each of the division surfaces, whereby there is an advantage of being capable of reducing the display gamma correction time by solving the problem that the time to sequentially output RGB colors during RGB correction is required in the test time.
