An embodiment of the invention discloses a display module gamma debugging method, a display module gamma debugging device and a display module. The display module gamma debugging method comprises thestep of dividing a display brightness level of the display module into a plurality of dimming intervals, wherein the plurality of dimming intervals at least comprise a first data voltage dimming interval and a second data voltage dimming interval, and the first brightness level binding point is the maximum display brightness level of the display module; the power supply voltage corresponding to the second brightness level binding point is greater than the power supply voltage corresponding to the first brightness level binding point, the maximum voltage of a gamma circuit corresponding to thesecond brightness level binding point is smaller than the maximum voltage corresponding to the first brightness level binding point, and the minimum voltage corresponding to the second brightness level binding point is greater than the minimum voltage corresponding to the first brightness level binding point; and in the first data voltage dimming interval, a PWM duty ratio, the maximum voltage and the minimum voltage of the gamma circuit, and the power supply voltage accessed to a cathode of a light emitting device in the display module are fixed. According to the display module gamma debugging method, the display module gamma debugging device and the display module, the power consumption of the display module can be reduced, and the gamma debugging efficiency can be improved.
Description
technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular to a gamma debugging method, device and display module. Background technique [0002] With the development of display technology, the image quality requirements of display products are also getting higher and higher. [0003] In the prior art, usually in the order of display brightness levels from high to low, from the highest display brightness level to a certain display brightness level is usually the data voltage dimming interval, and at least two groups of gammas are adjusted in the data voltage dimming interval. Improve the image quality of the display panel, but the above-mentioned existing solutions cannot satisfy the problem of saving power consumption and improving gamma efficiency at the same time. Contents of the invention [0004] The present invention provides a display module gamma debugging method, device and display module, so as to ...
