Embodiment Construction

[0031] 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.

[0032] As mentioned in the background art, the existing display panels have the problem of slow calibration during gamma calibration. After careful research, the inventors found that the reason for this technical problem is: during the gamma calibration process of the prior art, for For each binding point, the initial setting of the register value in the gamma register is not fixed, and the initial setting of the register value corresponding to each binding point is also irrelevant. When each binding point adjusts ...

Abstract

The embodiment of the invention discloses a gamma register calibration method, a gamma register calibration device and a display device. The gamma register calibration method comprises the steps of obtaining a first threshold point and a second threshold point by adjusting a register value of a gamma register; determining a linear prediction relational expression based on the first threshold pointand the second threshold point; obtaining a register prediction value under the target brightness value based on the linear prediction relational expression; correcting the register prediction valueby adjusting the register value of the gamma register to obtain a third threshold point; dividing the brightness sections corresponding to the first threshold point and the second threshold point intotwo new brightness sections by using the third threshold point; and taking one threshold point corresponding to the two end points of each new brightness section as a new first threshold point, taking the other threshold point as a new second threshold point, and returning to execute the step of determining the linear prediction relational expression based on the first threshold point and the second threshold point. According to the embodiment of the invention, the calibration speed of the gamma register can be improved.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a gamma register calibration method, a gamma register calibration device, and a display device. Background technique [0002] With the development of the display technology, the application of the display panel is becoming more and more extensive, and the display panel must be gamma calibrated before leaving the factory, so that the brightness and color coordinates of the display panel can meet the requirements. [0003] However, when gamma calibration is performed on existing display panels, the calibration takes a long time, which seriously affects the overall adjustment speed of the display panel production line. Contents of the invention [0004] Embodiments of the present invention provide a gamma register calibration method, a gamma register calibration device and a display device, so as to improve the calibration speed of the gamma register. [0005] In...
