Problems solved by technology

[0002] With the large number of applications in the field of liquid crystal display module mobile phones and the innovation of display technology, people have higher and higher requirements for the consistency of the gamma curve of the liquid crystal display module. Even if it is the same model, there are obvious differences in the Gamma curves of different LCD modules. In terms of user experience, this difference is manifested as white or dark visually; this requires reducing the Gamma curve difference between each LCD module in small batch production
Existing methods for controlling the Gamma curve cannot 100% guarantee that all LCD module Gamma curves are within the control range during mass production, and products that exceed the range can only be scrapped, which increases production costs

[0073] Please combine figure 2 , based on the first embodiment of the present invention, in the second embodiment of the present invention, before step S102, the gamma adjustment method further includes steps:

[0074] S109: Obtain multiple gamma partition interval ranges and convert the multiple gamma partition interval ranges into multiple transmittance partition interval ranges;

[0075] The gamma partition interval range can be set according to the gamma control range, and the gamma partition interval covers the gamma control range. For example, when the gamma control range is Gamma=2.1-Gamma=2.3, the gamma partition interval range may be Gamma=1.9-Gamma=2.1, Gamma=2.1-Gamma=2.3, Gamma=2.3-Gamma=2.5. Of course, the range of the gamma partition interval is not limited to the above-mentioned range, and the above-mentioned partition interval range is only for illustration. In practical applications, the gamma partition range can be divided into smaller or larger according t...

[0107] see Figure 6 , based on the fifth embodiment of the present invention, in the sixth embodiment of the present invention, the gamma adjustment method further includes the steps:

[0108] S122: When the measured transmittance is not within the transmittance control range, determine whether all standard gamma parameters have been set as test gamma parameters respectively;

[0109] The standard gamma parameters in the gamma database are limited. When all standard gamma parameters have been set as test gamma parameters and the measured transmittance is still not within the transmittance control range, in order to avoid setting the same standard gamma parameters to Gamma parameters are set to test gamma parameters, resulting in repeated useless steps in the gamma adjustment process. When the measured transmittance is not within the transmittance control range, it is necessary to judge whether all standard gamma parameters have been set to test gamma parameter.

Abstract

The invention provides a gamma adjustment method and device, and a computer readable storage medium. The gamma adjustment method comprises the steps that a reference gamma parameter is set as a testing gamma parameter; the testing gamma parameter is used for driving a to-be-adjusted liquid crystal display module; the actually-measured transmittance of the to-be-adjusted liquid crystal display module is obtained when the testing gamma parameter drives the to-be-adjusted liquid crystal display module; whether the actually-measured transmittance is within the control range of the transmittance ornot is judged; if yes, the testing gamma parameter is stored into an integrated circuit of the to-be-adjusted liquid crystal display module; and if not, one standard gamma parameter is selected sequentially from the multiple gamma standard parameters to be set as a testing gamma parameter, and the step that the testing gamma parameter is used for driving the to-be-adjusted liquid crystal displaymodule until the actually-measured transmittance is within the control range of the transmittance is conducted. According to the gamma adjustment method and device, the gamma values of all the liquidcrystal display modules can be within the control range when the liquid crystal display modules are produced in batches, the situation that products exceeding the range are scrapped is avoided, and the production cost is lowered.
