Embodiment Construction

[0014] A compensation device for adjusting the brightness of a display, which includes a control unit 1, a screen brightness detection unit 2 and a brightness compensation unit 3; the screen brightness detection unit 2 detects the brightness of a display backlight after aging and transmits an actual brightness signal to the control unit 1; The control part 1 compares the actual brightness signal with the standard brightness range set by the display, and when the actual brightness is lower than the standard brightness range, sends the detection result to the brightness compensation part 3; the brightness compensation part 3 backlights the display according to the brightness detection result. Lamp current is adjusted.

[0015] A timer is provided in the control part 1, and after the control part 1 confirms that the display reaches the set aging time through the timer, the screen brightness detection part 2 starts to detect the brightness of the backlight of the display after agin...

Abstract

The invention discloses a compensation device for adjusting display brightness and an adjusting method, the device comprises a control part, a picture brightness detection part and a brightness compensation part; the picture brightness detection part detects brightness of aged display backlight lamp and conveys actual brightness signal to the control part; the control part compares the actual brightness signal to the standard brightness range set by the display, when the actual brightness is lower than the standard brightness range, the detected result is conveyed to the brightness compensation part; the brightness compensation part adjusts the current of the display backlight lamp based on the detected result of the brightness. The invention can improve the brightness of the liquid crystal screen and make the display effect of the LCD better after the liquid crystal screen is aged.

Description

technical field [0001] The invention relates to a crystal display, in particular to a compensation device for adjusting the brightness of the display according to the aging characteristics of the liquid crystal screen and an adjustment method for the compensation device. Background technique [0002] Liquid crystal displays have been widely used. When the liquid crystal display is used for a certain period of time, due to the aging of the liquid crystal screen, the brightness of the liquid crystal display will decrease accordingly, and the display effect will deteriorate. As the aging time of the LCD screen increases, the brightness of the LCD will gradually decrease. When the LCD screen ages to a certain extent, the reduction in brightness will become very obvious, thus affecting the display effect. [0003] After the current liquid crystal display leaves the factory, it will not compensate for the brightness of the liquid crystal screen due to the aging of the liquid cry...
