Abstract

The embodiment of the invention provides a display panel, a driving method thereof and a display device, relates to the technical field of display, and aims to improve the threshold voltage detection precision. The display panel includes a display area, the display area including a light emitting element and a pixel circuit connected to the light emitting element, the pixel circuit including: a driving transistor connected between a first fixed potential signal line and a first pole of the light emitting element; the data writing module is connected between a data line and the grid electrode of the driving transistor; the detection module is connected between the first pole of the light-emitting element and the detection signal line; a first pole plate of the storage capacitor is electrically connected with the grid electrode of the driving transistor; the charging control module comprises a first capacitor and a control unit, the first capacitor is connected between the second pole plate of the storage capacitor and the first pole of the light-emitting element, and the control unit is connected with the first pole plate of the first capacitor and the second pole plate of the first capacitor and used for controlling the first capacitor to be charged in the detection time period and not to be charged in the compensation time period.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel, a driving method thereof, and a display device. 【Background technique】 [0002] An organic light-emitting diode (OLED) display panel includes an electrically connected pixel circuit and a light emitting element, and the pixel circuit is used to transmit a driving current to the light emitting element to drive the light emitting element to emit light. [0003] At present, in order to improve the brightness uniformity of the display panel, it is usually necessary to compensate the threshold voltage of the driving transistor in the pixel circuit. However, the detection accuracy of the threshold voltage in the prior art is relatively low, which leads to low compensation accuracy. 【Content of invention】 [0004] In view of this, an embodiment of the present invention provides a display panel, a driving method thereof, and a display device, so as to impro...
