Display panel and display device

Abstract

The invention relates to the technical field of liquid crystal display, in particular to a display panel and a display device. By the display panel and the display device, the quality of image display of the display panel is improved, and the problem that pictures on an existing display panel are greenish is solved. The display panel comprises a liquid crystal panel and a plurality of flexible printed boards; each flexible printed board is provided with a first common electrode signal wire, the liquid crystal panel comprises a common electrode route and a plurality of second common electrode signal wires, and the first common electrode signal wires of each two adjacent flexible printed boards are communicated with each other via the corresponding second common electrode signal wire; and the first common electrode signal wires in the flexible printed boards are communicated with one another via a conductor positioned on the outside of the liquid crystal panel. Accordingly, transmission resistance of Vcom signals transmitted from the flexible printed boards to the route Vcom can be reduced, the problem that pictures are greenish is solved, and the quality of image display of the display panel is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display panel and a display device. Background technique [0002] At present, the ADS (Advanced Super Dimension Switch, advanced super multi-dimensional switching technology) mode is widely used in large-size liquid crystal panels because of its large pixel capacitance, which improves the retention rate of the pixel voltage. Such as figure 1 As shown, the ADS mode display panel includes: a liquid crystal panel 100, several flexible circuit boards 110 (COF, Chip On Film) fixed on the periphery of the liquid crystal panel 100 and connected to the liquid crystal panel 100; wherein, the liquid crystal panel 100 includes: The internal common electrode Vcom trace 101, a plurality of second common electrode signal lines 102 (also called PLG signal lines, Pattern Line on Glass) arranged around the display area; each flexible circuit board 110 has a section of the first ...

AI Technical Summary

Problems solved by technology

However, with the increase of the size of the liquid crystal panel and the pixel capacitance, the display panel is under the specified detection picture (usually a white picture), and there is a gap between the data line (not shown in the figure) and the Vcom line 101 in the liquid crystal panel. In the overlapping area, the insulating layer between them can act as a dielectric, and a capacitance effect will occur when the voltage between the two changes. In a specific white detection screen, due to the capacitive coupling effect, the Vcom signal will follow when the data signal changes. Fluctuation, if this kind of fluctuation cannot be recovered in time, the voltage difference between the green pixel electrode and the Vcom electrode will become larger, causing the green pixel to become brighter, and the phenomenon of greenish (Greenish) will appear on the display panel, which will seriously affect the display of the display panel quality
