Problems solved by technology

However, the threshold voltage drift of the oxide thin film transistor will occur after a long time of operation, which seriously affects the reliability and stability of the circuit with the thin film transistor as the device. One of the important reasons for the threshold voltage drift of the thin film transistor is air Water vapor enters the interface of metal oxide and other film layers through the film, affecting the stability

Abstract

The invention discloses a display panel. The display panel comprises a substrate, an active layer, a structural layer, a passivation layer and a pixel definition layer. The active layer is arranged onthe substrate. The structural layer is arranged on the active layer and comprises an oxide semiconductor layer. The passivation layer is arranged on the structural layer and comprises an inorganic material layer and a titanium dioxide layer. The pixel definition layer is arranged on the passivation layer. A hydrophobic membrane structure is formed by the titanium dioxide layer under the catalysisof ultraviolet light.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. 【Background technique】 [0002] The thin-film transistor (thin-film transistor, TFT) array substrate is the main component in the current liquid crystal display device and active matrix organic light emitting diode (active matrix organic light emitting diode, AMOLED) display device, and is used to provide the drive for the display. circuit. The array substrate is usually provided with several gate scanning lines and several data lines, which together define a plurality of pixel units. Each pixel unit is provided with a thin film transistor and a pixel electrode. The gate of the thin film transistor is connected to the corresponding gate scanning line. When the voltage on the gate scanning line reaches the turn-on voltage, the source and drain of the thin film transistor are turned on. , so that the data voltage on the data ...
