Embodiment Construction

[0051] The technical solutions of the white balance realization method and system of the liquid crystal display module will be described in detail below with reference to specific embodiments and drawings to make it more clear.

[0052] Such as figure 1 As shown, in one embodiment, a method for realizing white balance of a liquid crystal display module includes the following steps:

[0053] In step S110, the model of the liquid crystal glass of the liquid crystal display module is obtained, and a target color coordinate is set for the liquid crystal glass of this model.

[0054] Specifically, there are many types of liquid crystal glass for liquid crystal display modules, such as LCD001, with a resolution of 300×400 and a transmittance of 6e. -2 Etc., where e is the base of natural logarithm, and the approximate value of e is 2.718. The set target color coordinates refer to the coordinates of the white balance color that is scheduled to be achieved, and can be set as required. The ...

Abstract

The invention relates to a method and a system for realizing white balance of a liquid crystal display module. The method for realizing the white balance of the liquid crystal display module comprises the following steps: obtaining the size of liquid crystal glass of the liquid crystal display module and setting a target color coordinate according to the size of the liquid crystal glass; obtaining a white frame color coordinate with the liquid crystal glass in the size matched with LEDs (Light Emitting Diodes) in different sizes and obtaining a chromatic aberration between each white frame color coordinate and the target color coordinate; selecting the sizes of a preset quantity of LEDs from small to big according to the chromatic aberration; and selecting an LED from the preset quantity of LEDs in the sizes as a backlight source of the liquid crystal display module. According to the method and the system for realizing the white balance of the liquid crystal display module, the LEDs matched with the liquid crystal glass in size are selected; compared with the traditional selection by continuously exchanging the LEDs, the method has the advantage that the time is saved; and the LEDs in all sizes are not needed to be purchased and only the tested and selected LEDs in the corresponding sizes are purchased, so that the cost is saved.

Description

Technical field [0001] The invention relates to the field of liquid crystal display, in particular to a method and system for realizing white balance of a liquid crystal display module. Background technique [0002] LCM (Liquid Crystal Display Module) is mainly composed of backlight, liquid crystal glass, polarizer, integrated circuit, and flexible circuit board. The design of LCM mainly includes structural design, electronic design and display effect design. Among them, display effect design is the most intuitive feature. [0003] The display effect design of LCM includes many parameters, and white balance design is one of them. The LCM white balance is mainly determined by the spectrum of the LED (Light Emitting Diode) in the backlight and the transmittance of the liquid crystal glass. Each type of LED emits a different spectrum, and each type of liquid crystal glass has a different transmittance to different wavelengths of visible light (light with a wavelength of 380 nanomete...
