Abstract

The invention discloses a display panel. The display panel comprises a plurality of sub-pixels, each sub-pixel comprises a driving circuit, and each driving circuit comprises a light-emitting device, a driving transistor, a first transistor, a first capacitor, a second transistor and a third transistor. A drain electrode of a first transistor is electrically connected with a grid electrode of a driving transistor, a source electrode of a third transistor is electrically connected with a source electrode of the first transistor, the first transistor is an oxide thin film transistor, and after the first transistor is closed, a light-emitting device is turned on to emit light. And after the first transistor is closed, the low leakage characteristic of the oxide thin film transistor is utilized to suppress the grid potential change of the driving transistor within one frame time, the potential stability of the grid of the driving transistor is improved, and the light emitting uniformity of the light emitting device is further ensured, so that leakage is controlled through the oxide thin film transistor, and high-quality display is realized. And low frequency and low power consumption are achieved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel. Background technique [0002] With the development of multimedia, display devices become more and more important. Correspondingly, the requirements for various types of display devices are getting higher and higher, especially in the field of smart phones, ultra-high-frequency drive displays, low-power drive displays, and low-frequency drive displays are all current and future development demand directions. [0003] P-channel metal oxide semiconductor field effect transistors (PMOS) are widely used as transistors for display devices, and low temperature polysilicon (LTPS) is widely used in the field of mobile phones. However, an Achilles' heel of LTPS is that the leakage current is relatively large, especially when displaying at low frequencies, the flicker is serious. [0004] In view of this, prior art needs improvement. Contents of the invention...
