Problems solved by technology

[0002] The display device usually provides data signals to the display panel through a source driver or a data controller, wherein the data controller includes a digital-to-analog converter, and the digital-to-analog converter is usually constructed by a plurality of drive transistors, and the multiple drive transistors pass through After a long period of use, the performance of the drive transistor will deteriorate or its characteristics will change, such as threshold voltage drift or mobility changes. As the refresh rate increases, especially at high refresh rates, there is a risk of insufficient charging of the sub-pixels, thereby Causes uneven display and affects display quality

Abstract

The invention discloses a display device and electronic equipment, the display device comprises a display panel, a gray scale sensing module, a time schedule controller and a data controller, and the gray scale voltage of a sub-pixel is sensed through the gray scale sensing module; then the time sequence controller determines the corresponding gamma compensation voltage according to the comparison result of the gray-scale voltage and the preset gray-scale voltage, and the data controller outputs the data signal adjusted by the gamma compensation voltage to the corresponding sub-pixel, so that the gray-scale voltage of each sub-pixel can be correspondingly adjusted, the condition of insufficient charging of the sub-pixel is improved, and the display quality is improved. And the influence of the parameter change of the driving transistor in the data controller on the insufficient charging of the sub-pixel is compensated.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display device and an electronic device. Background technique [0002] The display device usually provides data signals to the display panel through a source driver or a data controller, wherein the data controller includes a digital-to-analog converter, and the digital-to-analog converter is usually constructed by a plurality of driving transistors, and the plurality of driving transistors are After a long period of use, the performance of the drive transistor will deteriorate or the characteristics will change, such as threshold voltage drift or mobility change, as the refresh frequency increases, especially at high refresh frequencies, there is a risk of insufficient sub-pixel charging, thereby It will cause uneven display and affect the display quality. SUMMARY OF THE INVENTION [0003] The present application provides a display device and electronic equi...
