An embodiment of the present invention provides a method and device for adjusting panel brightness, and a screen driving board. The method includes: first dividing a panel to be adjusted into N regions, where N is an integer greater than or equal to 2; and acquiring corresponding RC value of each region in the N regions; adjusting the VGH voltage corresponding to each region according to the RC value of each region, so as to adjust the brightness of each region, wherein the RC value is used to indicate the delay time of the resistor and capacitor, and the VGH voltage is the turn-on voltage ofa gate of a thin film transistor (TFT). The method and device for adjusting the panel brightness and the screen driving board provided by the embodiment of the invention improve the flexibility of image quality adjustment under the condition of ensuring the uniformity of the image quality of a display, and reduce the production cost of the display and the module cost.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of electronic equipment, and in particular, to a method and device for adjusting brightness of a panel, and a panel driving board. Background technique [0002] With the continuous development of electronic equipment, the size of the display panel of the electronic equipment is also increasing continuously, so as to improve the user's experience of using the display. However, as the size of the display panel continues to increase, the uniformity of image quality becomes particularly important when displaying pictures through the display of the larger-sized panel. [0003] In the prior art, the brightness of the panel can be adjusted to ensure the uniformity of the display quality of the panel with a larger size. For example, by adding additional equipment in the panel manufacturing process, and photographing the panel through the additional equipment, and processing the data obtained f...
