titleOfInvention | Detection method, driving method, display device and construction method of compensation lookup table |
abstract | A pixel circuit detection method, a display panel driving method, a display device and a temperature compensation lookup table construction method are provided. The pixel circuit includes a drive transistor, the method comprising: applying a first data voltage to a gate of the driving transistor, acquiring a first sensing voltage at a first pole of the driving transistor for a first time period after the first data voltage is applied and before the driving transistor is turned off, wherein the first data voltage is equal to a sum of a detection data voltage and a first reference threshold voltage of the driving transistor; acquiring the current threshold voltage of the driving transistor based on the detection data voltage, the first sensing voltage and a temperature compensation lookup table. The temperature compensation look-up table includes a plurality of threshold voltages of the driving transistor at a plurality of temperatures and a plurality of sensing voltages acquired at the plurality of temperatures based on the first period and the detection data voltage. |
