Abstract

The invention discloses a display panel and a display device. Sector wires of the display panel are connected with data lines through a multiplexer, the multiplexer comprises a plurality of transistors, a first sector wire is connected with a first data line through a first transistor, a second sector wire is connected with a second data line through a second transistor, and the transistors are inone-to-one correspondence with the data lines; the resistance of the first sector wire is greater than that of the second sector wire, the first transistor is a low-temperature polycrystalline silicon thin film transistor, and the second transistor is an oxide thin film transistor. According to the invention, the resistance of the sector wires at different positions can be balanced, the load difference of the data lines correspondingly connected with the sector wires at different positions is balanced, and the difference of charging capacities of different data lines is relieved, so that a better display effect is obtained.

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...
