Problems solved by technology
The brightness adjustment range of the brightness adjustment device of the liquid crystal module is only divided into equal parts, and can only do rough brightness output, cannot achieve precise subdivision, and cannot meet the test requirements
Such as liquid crystal display, it can only draw R, G, B (red, green and blue) grayscale images by manually controlling the drawing software, and then increase or decrease the brightness by adjusting the brightness buttons "+" and "-". Coarse adjustment of the brightness of the LCD module. This adjustment method has fewer adjustment levels and cannot output accurate brightness values.
At present, there is no device on the market for precise adjustment of the brightness value of the liquid crystal module, which cannot achieve accurate subdivision and cannot meet the test requirements.

Description
technical field [0001] The invention relates to the technical field of liquid crystal module testing, in particular to a device and method for adjusting brightness of a liquid crystal module. Background technique [0002] Currently. The brightness adjustment range of the brightness adjustment device of the liquid crystal module is only divided into equal parts, and can only do rough brightness output, cannot achieve precise subdivision, and cannot meet the test requirements. Such as liquid crystal display, it can only draw R, G, B (red, green and blue) grayscale images by manually controlling the drawing software, and then increase or decrease the brightness by adjusting the brightness buttons "+" and "-". Coarse adjustment of the brightness of the liquid crystal module, this adjustment method has fewer adjustment levels, and cannot output accurate brightness values. At present, there is no device on the market to precisely adjust the brightness value of the liquid crystal...
