Embodiment Construction

[0023] The display screen in the traditional technology is prone to display failure problems, such as black spots, bright spots, and colorful spots in the display area of ​​the display screen. The research of the inventors found that the root cause of this problem is that the display screen The shock absorption and cushioning effect of the display screen is not good. When a heavy object hits the display screen, the stress on the display screen is difficult to release, which may cause the display screen to break or the components inside the display screen to be damaged. The display panel is the main functional area of ​​the display screen. Improving the shock and shock resistance of the display panel can effectively improve the display failure problem of the display screen.

[0024] In order to solve the above problems, the inventors add a buffer layer between the pixel defining layer and the encapsulation structure. Specifically, a buffer layer close to the supporting pillars ...

Abstract

The invention relates to a display panel, comprising: an array substrate (1); A plurality of light emitting units (2) are arranged on the surface of the array substrate; A pixel defining layer (3) having a plurality of openings accommodating a light emitting unit; A plurality of support columns (4) disposed on the pixel defining layer and corresponding to the pixel defining layer; And a buffer layer (5) disposed adjacent to and on the same layer as the support pillar and having a height higher than the height of the support pillar. A display panel of the present invention and a display devicehaving the same, By reasonably arranging a buffer layer around the support column, Avoid the damage of supporting pillar caused by external impact stress which can not be dispersed, and at the same time avoid damage to the functional devices such as nearby light-emitting units. By enhancing the impact resistance and shock-proof ability of the display panel, the bad phenomena such as black spots, bright spots and color spots in the display area, and effects on the product quality of the display screen are ultimately prevented.

Description

technical field [0001] The invention belongs to the technical field of display screens, and in particular relates to a display panel and a display device having the same. Background technique [0002] After several generations of improvements, OLED display devices have gradually matured in technology, and have been favored by more and more manufacturers, and are gradually adopted in various electronic products. Compared with screens made of LCD and other materials, OLED screens have obvious advantages such as thinness and bendability. On the other hand, the market also puts forward higher requirements for the structural strength and anti-collision performance of OLED series products. When the OLED display is hit by a heavy object, the support column is often damaged due to stress concentration and cannot be dispersed, and even the related components under the support column of the display panel are damaged, which eventually leads to black spots, bright spots, and colorful sp...
