Embodiment Construction

[0048] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0049] As mentioned in the background technology, in the prior art, when performing the color calibration test and calculation of the display module, there is a problem that the calculation of the color calibration of the display module is inaccurate, resulting in After compensation, the display picture quality is still poor. The inventor found that the reason for the above problems is that in the prior art, when testing the color accuracy of the display module, usually only the two-dimensional color coordinates o...

Abstract

The embodiment of the invention discloses a compensation method and device for a display panel. The method comprises the following steps: determining target color coordinates and target brightness ofa plurality of test pictures according to a color system of a display module and white standard color coordinates; obtaining test color coordinates and test brightness of the display module under eachtest picture; determining a color calibration structure according to the target color coordinates, the test color coordinates, the target brightness and the test brightness corresponding to each testpicture; and compensating the display module according to the color alignment structure. According to the technical scheme of the embodiment, when the color alignment structure is determined, the color coordinate factor and the brightness factor are considered, so that the calculation accuracy of the color alignment structure is improved, accurate compensation data can be obtained when the display module is compensated according to the color alignment structure, and the display image quality of the display module 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 compensation method and device for a display module. Background technique [0002] With the development of display technologies, the display quality requirements for display images are also getting higher and higher. [0003] The color standard of the display module affects the display quality of the display screen. In the prior art, when performing the color calibration test and calculation of the display module, there is a problem that the calculation of the color calibration of the display module is inaccurate, resulting in that after the display module is compensated according to the color calibration of the display module, the quality of the displayed picture is not good enough. Still poor. Contents of the invention [0004] The invention provides a compensation method and device for a display module to realize accurate calculation of the...
