Abstract

The invention relates to a display panel and a compensation data transmission method, and the method comprises the steps: generating feature compensation data; transmitting the feature compensation data to a first storage unit; transmitting the feature compensation data stored in the first storage unit to a second storage unit. According to the embodiment of the invention, the compensation data transmission method does not need a Flash memory. A screen module group does not need to be provided with the Flash memory, thereby reducing the physical space occupied by the Flash memory in the screenmodule group. In the embodiment of the invention, the method can generate the feature compensation data through the Mura compensation data, and the feature compensation data is directly stored in a data drive circuit. The method reduces the error codes in the transmission process of the feature compensation data. The method does not need an additional Flash memory on the screen module group, thereby reducing the data transmission link, improving the data transmission efficiency, and reducing the design cost of the display panel.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a compensation data transmission method. Background technique [0002] At present, Active Matrix Driving OLED (AMOLED for short) has the advantages of self-illumination, high display contrast, thin thickness, wide viewing angle, fast response speed, wide operating temperature range, simple structure and manufacturing process, etc. properties are widely used. However, the current of the organic light-emitting diode will vary with the shift of the threshold voltage of the driving transistor, so that the AMOLED display panel will have non-uniform display brightness Mura (color spot defect). The Mura phenomenon means that the actual brightness of some pixels is darker or brighter than the theoretical brightness that should be displayed, thereby affecting the brightness uniformity and brightness constancy of the AMOLED display panel. [0003] At presen...
