Problems solved by technology

However, due to the longer holding time of the internal nodes of the drive circuit (Gate Driver On Array, GOA) during the low-frequency implementation process, the stability of the circuit-level transmission is reduced and the GOA circuit is prone to failure, resulting in split-screen phenomenon, which reduces the display effect

Abstract

The invention provides a display panel, a gate drive circuit and an electronic device, and the display panel comprises a gate drive region. The gate drive region comprises a first metal layer which isdisposed on a polycrystalline silicon semiconductor layer and comprises a first grid electrode; a second metal layer which is arranged on the first metal layer, and comprises a first source electrode, a first drain electrode and a second grid electrode, wherein the two ends of the polycrystalline silicon semiconductor layer are electrically connected with the first source electrode and the firstdrain electrode respectively; a metal oxide semiconductor layer which is arranged on the second metal layer; and a third metal layer which is arranged on the metal oxide semiconductor layer, and comprises a second source electrode and a second drain electrode; the two ends of the metal oxide semiconductor layer are electrically connected with the second source electrode and the second drain electrode respectively. According to the display panel, the gate drive circuit and the electronic device, the level transmission stability of the circuit can be improved, and the display effect can be improved.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel, a grid driving circuit and an electronic device. 【Background technique】 [0002] The LTPO (Low Temperature Polycrystalline-Si Oxide) low temperature polycrystalline oxide process combines two processes of low temperature polysilicon (LTPS, Low Temperature Poly Si) and metal oxide (Oxide), that is, the formation of the first A thin film transistor and a second thin film transistor. [0003] Using LTPO technology can extend the application of the device to the field of ultra-low frequency display to achieve the purpose of optimizing power consumption. However, due to the longer holding time of the internal nodes of the drive circuit (Gate Driver On Array, GOA) during the low-frequency implementation process, the stability of the circuit-level transmission is reduced and the GOA circuit is prone to failure, resulting in split-screen phenomenon, which red...
