Abstract

The invention discloses a display panel and a display device. The sector wiring of the display panel is connected to the data line through a multiplexer, and the multiplexer includes a plurality of transistors, wherein the first sector wiring is connected to the first data line through the first transistor, and the second sector The wiring is connected to the second data line through the second transistor, and the transistor corresponds to the data line one by one; the resistance of the wiring in the first sector is greater than the resistance of the wiring in the second sector, the first transistor is a low-temperature polysilicon thin film transistor, and the second The transistors are oxide thin film transistors. The present invention can balance the resistance of wiring in different sectors, balance the load difference of data lines correspondingly connected to wiring in different sectors, alleviate the difference in charging capabilities of different data lines, and thus obtain better display effects.

Description

technical field [0001] The present invention relates to the display field, and more specifically, to a display panel and a display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display, also known as organic electroluminescent display, is a new type of flat panel display device, due to its simple preparation process, low cost, low power consumption, high luminance, Wide range of working temperature, light and thin size, fast response speed, easy to realize color display and large-screen display, easy to realize matching with integrated circuit driver, easy to realize flexible display, etc., so it has broad application prospects. [0003] According to the driving method, OLED can be divided into two categories: passive matrix OLED (Passive Matrix OLED, PMOLED) and active matrix OLED (Active Matrix OLED, AMOLED), namely direct addressing and thin film transistor (ThinFilm Transistor, TFT) matrix Two classes of addressi...
