Embodiment Construction

[0030] The technical solutions in the embodiments of the disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the disclosure. Apparently, the described embodiments are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present disclosure.

[0031] In the embodiment of the present disclosure, as figure 1 as shown, figure 1 It is a top view of the display panel of the disclosed embodiment. The display panel 100 includes a display area 102 , a terminal area 103 and conductive terminals 101 . Wherein, the display area 102 is arranged adjacent to the terminal area 103, and the conductive terminals 101 are arranged along both sides of the outer edge of the display area 102 of the display panel 100, and the conductive terminals...

Abstract

The invention provides a display panel and a display device. The display panel comprises a color film substrate and an array substrate; the color film substrate comprises a display area and a terminalarea; the terminal area comprises a first supporting column, the display area comprises a second supporting column, the upper end of the first supporting column and the upper end of the second supporting column are both arranged on the color film substrate, and the surface area of the lower end face of the first supporting column is not smaller than that of the lower end face of the second supporting column. When the upper substrate and the lower substrate of the display panel are stressed, the deformation quantity of the first supporting columns is small, and a sliding distance is small; after an external force is removed, the first supporting columns can rapidly recover to the initial state, the consistency of a box thickness of the terminal area of the display panel is still good, andthe display brightness of a display screen is uniform.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] Local non-uniform brightness (Mura) is a common display defect problem of display panels, and its main performance is inconsistency in local display brightness of the display screen. There are various causes of mura. [0003] Among them, the abnormal local box thickness during the vacuum assembly process is also a major factor leading to Mura. In the currently designed display panel structure, in the paired structure of the color filter (color filter, CF) substrate and the thin film transistor (thin film transistor, TFT) substrate, after the two groups of substrates are paired, the gap between the CF substrate and the TFT substrate is It is evacuated, and under the action of atmospheric pressure, the CF substrate and the TFT substrate are firmly bonded together, thereby causing the problem of inc...
