<p>A method and an apparatus for correcting gamma value of a LCD screen are provided, in order to solve the problem that LCD screens in the prior art can only control the gamma value of the LCD screens through adjusting the brightness of the white backlight to balance the brightness, chroma and contrast of the LCD screens, but are unable to control each gamma value of the three colors of RGB independently, which causes the problem of color shift and chromatic aberration. By utilizing the method of adjusting each gamma value of the three colors of RGB, namely red, green and blue light independently, the present invention improves the display effect of the LCD screen. And the present invention optimizes the display effect through readjusting the value of the current working state of the LCD screen.</p> |
