Abstract

The invention provides an OLED pixel layout and a method for manufacturing an OLED device, wherein the OLED pixel layout includes: a switching transistor, a driving transistor, a storage capacitor, an organic light emitting diode, a scanning line, a data line and a power supply line; a switching transistor, a driving transistor , the storage capacitor, the organic light emitting diode, the scanning line, the data line and the power supply line are electrically connected; wherein, a first through hole is opened at the drain of the switching transistor, and the gate of the driving transistor is connected to the switching transistor through the first through hole. drain connection. In the OLED pixel layout and the manufacturing method of the OLED device provided by the present invention, a new type of pixel layout is adopted. When making an OLED device, only one through hole is required to expose the drain of the switching transistor, and the gate of the driving transistor is directly passed through the through hole. The hole is connected to the drain of the switching transistor, thereby reducing the area of ​​a contact hole and a metal trace, so the area of ​​the pixel can be reduced, thereby increasing the resolution of the display.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to an OLED pixel layout and a method for manufacturing an OLED device. Background technique [0002] With the development of the information society, people's demand for display devices is increasing day by day. In order to meet this requirement, various flat panel display devices such as Thin Film Transistor Liquid Crystal Display (TFT-LCD), Plasma Display (PDP), and Organic Light Emitting Display (OLED) have been rapidly developed. Among flat-panel displays, organic light-emitting displays (OLEDs) have many advantages such as active light emission, high contrast ratio, fast response speed, and thinness, and are gradually occupying a dominant position in flat-panel displays. At present, organic light-emitting displays (OLEDs) have been widely used in various high-performance display fields such as mobile phones, televisions, computers, and smart watches.
