Abstract

The invention discloses a gamma debugging method and apparatus of a display panel. A resistance value can be obtained simply through determining a voltage difference between first voltages when the display panel displays a blackest image and second voltages when the display panel displays a whitest image and currents of a gamma circuit in the display panel; then directly through determining whether the obtained resistance value is within a reference scope of the display panel during design, whether an initial gamma voltage calculation table needs to be adjusted is determined; If so, it is determined that the initial gamma voltage calculation table accords with a standard and does not need to be adjusted and a register value is determined; and if not, the initial gamma voltage calculation table is adjusted directly through the resistance value so as to determine a new register value, the register value corresponding to each gray scale can be directly and rapidly computed, and finally, according to the determined register value corresponding to each gray scale, gamma burning is performed on the display panel, such that a gamma debugging method can be simplified, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a gamma debugging method and device for a display panel. Background technique [0002] Due to the instability of the production process, there will be a problem of gamma inconsistency between different display panels. In order to solve this problem, the gamma of each display panel is generally debugged before the display panel leaves the factory. Existing gamma debugging equipment generally tests the grayscale and corresponding brightness of each debuggable adjustment point supported by the driver IC, and repeatedly communicates with the controller to debug to obtain the best register value corresponding to each grayscale . However, the above debugging method requires many adjustment points to be debugged, which makes the overall debugging process more complicated and time-consuming, thus reducing the generation efficiency. [0003] Therefore, how to make the gamma debugging m...
