Abstract

The embodiments of the present invention disclose a driving circuit and a display device. The driving circuit includes a first scanning driving circuit, a second scanning driving circuit, a selector and at least one pixel unit; the first scanning driving circuit and the second scanning driving circuit are electrically connected with the selector; the selector is electrically connected with the at least one pixel unit; and the selector is used for transmitting first scanning driving signals of the first scanning driving circuit to the at least one pixel unit in a first time period so as to make the at least one pixel unit be in a display state, and transmitting the second scanning driving signals of the second scanning driving circuit to the least one pixel unit in a second time period so as to make the at least one pixel unit be in a compensation state, wherein the first time period is different from the second time period. With the driving circuit and the display device of the invention adopted, the consistency of the display of the pixel units can be ensured, and therefore, the display effect of an organic light emitting diode can be improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a driving circuit and a display device. Background technique [0002] A traditional organic light-emitting diode (Organic Light-Emitting Diode, OLED) driving circuit is at least composed of 2T1C, that is, a switching thin film transistor, a driving thin film transistor and a storage capacitor, so as to realize stable display of the OLED. However, due to reasons such as long-time work of the OLED driving circuit, the driving thin film transistor is subjected to severe voltage stress, which will cause the threshold voltage of the driving thin film transistor to drift, thereby affecting the brightness of the OLED, causing each pixel unit of the display panel to display Inconsistent. Contents of the invention [0003] Embodiments of the present invention provide a driving circuit and a display device, which can ensure the consistency of display by pixel units, thereby improvin...
