| titleOfInvention | Detection method of pixel circuit, driving method of display panel and display device |
| abstract | A pixel circuit detection method, a display panel driving method and a display device are provided. The pixel circuit comprises a driving transistor, and the detection method of the pixel circuit comprises the following steps: in a first charging period, a first data voltage is applied to a gate of a driving transistor, a first sensing voltage is obtained at a first pole of the driving transistor for a first time period after the first data voltage is applied, and whether the first sensing voltage is equal to a reference sensing voltage or not is judged. The reference sensing voltage is obtained in a reference charging period in which the reference sensing voltage is obtained at the first pole of the driving transistor for a first time period after the reference data voltage is applied to the gate of the driving transistor and before the driving transistor is turned off, and the first data voltage is equal to the reference data voltage. The detection method can realize the detection of the threshold characteristic of the pixel circuit in the starting state, thereby improving the threshold compensation effect and the brightness uniformity. |
