[0041] refer to image 3 , image 3 It is the first embodiment of the color generation method based on the liquid crystal display module of the present invention, and the color generation method based on the liquid crystal display module includes the following steps:
[0042] Step S10, sequentially acquire the gray value of each pixel to be displayed according to the preset order;
[0043] The present invention utilizes the method of time-mixing method to make liquid crystal display module image, and this method utilizes the visual inertia of human eye (for the light stimulus of medium brightness, the duration of vision is about 0.05s to 0.2s, and the duration of vision is about 0.05s to 0.2s. is the reaction time of the optic nerve of the retina), as long as the liquid crystal display module sequentially presents the three primary color lights at the same place on the same surface of the display screen, the human eye will feel that the three primary color lights appear at th...

Disclosed is a colour generation method for a liquid crystal display module. The colour generation method for a liquid crystal display module comprises the following steps: successively acquiring, in a pre-set order, greyscale values of pixel points (S10); controlling a three-primary-colour light source (10) so same successively emits light of different primary colours according to a pre-set switching frequency, and controlling the turning on of thin-film transistor switches (42) corresponding to display positions of the pixel points (S20); generating a corresponding pulse signal according to the greyscale value of a current pixel point and the display position of the pixel point (S30); and sending the pulse signal to a drive circuit, and the drive circuit loading, according to the pulse signal, a corresponding pulse current to a corresponding thin-film transistor (41) (S40). Further provided are a colour generation apparatus for a liquid crystal display module, a liquid crystal display module, and a readable storage medium. Production costs of the liquid crystal display module can be reduced.
Description
technical field [0001] The invention relates to the technical field of televisions, in particular to a color generation method, device and readable storage medium based on a liquid crystal display module. Background technique [0002] With the improvement of people's living standards, non-radiation and flicker-free LCD TVs have gradually become standard household appliances for every family. [0003] LCD screen is an important part of LCD TV. It is mainly composed of backlight, polarizer, LCD screen, glass substrate, filter film and transparent electrode. The backlight used by the liquid crystal display is a white light backlight, so the liquid crystal display needs to use a filter film to filter the white light passing through the liquid crystal screen to obtain the primary color light source, so as to display the set color on the glass substrate. However, due to the high production cost of the filter film, the cost of the liquid crystal display is relatively high. Conte...
