The present invention relates to the field of display technology, and proposes a threshold voltage acquisition method, a pixel compensation method, and a display panel. The threshold voltage acquisition method is used to acquire the threshold voltage of a transistor in a sub-pixel unit of the display panel. The method includes: establishing A database of the mobility and temperature of the transistor, the database including a mapping relationship between mobility and temperature; obtaining an initial temperature and an initial threshold voltage at the initial temperature; sensing the current mobility, and obtaining the current temperature according to the database; A linear relationship between the threshold voltage and temperature is established, and the current threshold voltage is obtained by using the linear relationship according to the initial temperature, the initial threshold voltage, and the current temperature. The threshold voltage acquisition method provided in the present disclosure can quickly and accurately acquire the current threshold voltage.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a threshold voltage acquisition method, a pixel compensation method and a display panel. Background technique [0002] When the display panel is turned on for a long time, the threshold voltage and mobility of the transistor in the sub-pixel unit will shift with the change of temperature. When the mobility and threshold voltage of the transistor shift, the performance of the transistor will be changed, which will cause faults such as image sticking on the display panel. [0003] In the related art, the mobility and the threshold voltage are usually acquired in real time by sensing the mobility and the threshold voltage, so as to compensate the mobility and the threshold voltage of the transistor. [0004] However, in the related art, it takes a long time to sense the threshold voltage, and the actual threshold voltage of the transistor has changed during the threshold voltage s...
