Embodiment 1

[0031] figure 1 The implementation flow of the method for adjusting the brightness of the liquid crystal splicing system provided by Embodiment 1 of the present invention is shown, and the details are as follows:

[0032] In step S101, the brightness value, contrast value, and backlight value of each display unit in the liquid crystal splicing system are all adjusted to 100.

[0033] In this embodiment, firstly, the signal generator inputs 100% white signal to the core module of the display unit, and then the debugging control terminal adjusts the splicing of the display unit through the communication interface connected to the core module of the display unit, such as a serial port. The brightness value, contrast value, and backlight value of each display unit in the system are all 100.

[0034] In step S102, the brightness of each display unit is monitored, and the register value corresponding to the backlight value 100 is adjusted at the same time until the brightness of ea...

Abstract

The invention is suitable for the technical field of display units, and provides a method and a device for adjusting brightness of a liquid crystal splicing system. The method comprises the following steps: adjusting a brightness value, a contrast value and a backlight value of each display unit in the liquid crystal splicing system to 100; monitoring the brightness of each display unit, and adjusting a register value corresponding to the backlight value 100 until the brightness of each display unit meets the predetermined standard; figuring up a register value corresponding to the other predetermined backlight value according to the register value corresponding to the backlight value 0 and the register value corresponding to the backlight value 100; generating multiple backlight curves according to the backlight value and the register value corresponding to the backlight value; and adjusting the brightness of each display unit according to the input backlight value and a backlight curve corresponding to the backlight value. According to the invention, consistency of the brightness of each display unit in the large-screen liquid crystal splicing system is ensured.

Description

technical field [0001] The invention belongs to the technical field of display units, and in particular relates to a method and a device for adjusting the brightness of a liquid crystal splicing system. Background technique [0002] LCD large screen splicing system has become a major application in the field of monitoring technology. The quality of the image quality of the LCD large-screen splicing system depends on the subjective color difference of each LCD screen in the splicing system, and the premise of adjusting the color difference is to adjust the brightness consistency of each LCD screen. [0003] In order to adjust the brightness consistency of each LCD screen, the usual method is to correct the parameter GAMMA value of each LCD screen. This is time-consuming and laborious, and the production efficiency is greatly reduced, which cannot meet the needs of mass production. Contents of the invention [0004] Embodiments of the present invention provide a method, dev...
