Problems solved by technology

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 spots in the display area.

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 display panel involved in the present invention comprises: an array substrate (1); several light-emitting units (2), arranged on the surface of the array substrate; a pixel definition layer (3), having several openings for accommodating the light-emitting units; several support columns (4 ), located on the pixel definition layer and corresponding to the pixel definition layer; and a buffer layer (5), the buffer layer is close to the support pillar and arranged on the same layer as the support pillar, and the height of the buffer layer is higher than The height of the support column. The display panel of the present invention and the display device having the same can avoid damage to the support column caused by the inability to disperse the impact stress of an external force by reasonably setting a buffer layer around the support column, and at the same time avoid damage to functional devices including the nearby light-emitting unit, By enhancing the anti-shock ability of the display panel, it can finally prevent the occurrence of black spots, bright spots, colorful spots and other undesirable phenomena in the display area, which will affect the product quality of the display.

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...
