Back light regulating method for plane display

Abstract

A method for adjusting backlight source of plane display device, which contains switching on display screen, detecting backlight module of odd number or even number in said plane display device, if the number of backlight module is odd number then driving a backlight module in most central area, if the number of backlight module is even number then driving one of two backlight modules in cost central area, switching on backlight module in one side adjacent the central area, next time switching on the backlight module in another side adjacent the central area and switching off backlight module in central area, according to this order to switching on all backlight modules extended from center to the outer and then switching off all backlight modules from outer to center to complete a circulation, displaying whether the image is off, if it is not off then repeating above steps, then ending.

Description

technical field [0001] The invention relates to a method for adjusting a backlight source used in a flat panel display, in particular to a method for improving uneven brightness of a picture by changing the light emitting sequence of a backlight module. Background technique [0002] The development of electronic products is only a matter of recent decades, but its development speed exceeds that of other industries, especially computer-related peripherals and audio-visual audio-visual products. Great progress has been made, and new products are constantly being launched. For example, the display (Display), the traditional display is made of a traditional image tube, which has the following disadvantages: [0003] 1. Traditional displays are non-planar, so images on the screen will be distorted when viewed. [0004] 2. The image tube consumes a lot of power in terms of electricity, which means that it consumes a lot of power, and at the same time, it will generate high tempe...

AI Technical Summary

Problems solved by technology

[0003] 1. The traditional display is non-planar, so the image on the screen will be distorted when viewed

[0004] 2. The image tube consumes a lot of power in terms of electricity, which means that it consumes a lot of power, and at the same time, it will generate high temperature and heat of the display

[0005] 3. Limited by the large size of the traditional image tube, the size of the display cannot be reduced, and sometimes it is inconvenient to use because the space is too small

When using the traditional lighting mode of the backlight module, for example, when some light tubes in the upper half of the screen are turned on, some light tubes in the lower half of the screen are turned off. The problem of uneven brightness of the picture can still be noticed, and the manufacturing quality of the liquid crystal display screen will be doubted, so how to avoid this phenomenon becomes the problem that the present invention intends to improve
