Display panel and display device

Abstract

The invention discloses a display panel and a display device. The display panel comprises a substrate, multiple signal lines, multiple pixel areas, multiple fan-out leads, a connecting portion and multiple connecting lines, the substrate is provided with a display area, a fan-out area and multiple driving chips, the signal lines are formed in the display area, the pixel areas are formed in the display area and coupled with the signal lines, the fan-out leads are formed in the fan-out area, one ends of the fan-out leads are connected with the signal lines while the other ends of the same are connected with the driving chips, the connecting portion is formed in the fan-out area, the connecting lines are formed in the connecting portion, the driving chips are connected through the connecting lines, and the fan-out leads are arranged corresponding to the connecting portion in position. The connecting portion for communicating the driving chips is arranged in the fan-out area, so that the fan-out leads in the fan-out area is corresponding arranged in limited space, spatial layout is reasonably optimized, resistance value difference among the fan-out leads is reduced, color cast is improved and even eliminated, and display quality is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Existing displays are generally controlled based on active switches, which have many advantages such as thin body, power saving, and no radiation, and have been widely used, mainly including liquid crystal displays, OLED (Organic Light-Emitting Diode) displays, QLED (Quantum Dot Light Emitting Diodes) displays, plasma displays, etc. From the perspective of appearance and structure, there are both flat-panel displays and curved-surface displays. [0003] For liquid crystal displays, including two parts of the liquid crystal panel and the backlight module (Backlight Module), the working principle of the liquid crystal display is to place liquid crystal molecules in two parallel glass substrates, and apply a driving voltage on the two glass substrates to control the liquid crystal. The direction of rotatio...

[0006] However, the resistance value of each line in the Fan-out (fan-out area) is not necessarily equal due to space and other reasons. Sometimes the difference between the maximum and minimum is too large, resulting in an unsmooth display of the screen, especially in the mixed-color screen. The resistance of the outermost fan-out wire is too large, and the RC delay is serious. The charging rate of the latter pixel is higher than that of the previous pixel, and color shift will appear on both sides of the driver chip, which will affect the display quality and reduce the user's visual experience.
