Embodiment Construction

[0019] The above is aimed at the problem that the display device in the traditional technology is prone to display failure, such as black spots, bright spots, and colorful spots in the display area of ​​the display device. The research of the inventors has found that a major reason for this problem is that the display The impact resistance of the panel is not good. For example, when a heavy object hits the display device, the external force received by the display panel is difficult to release, resulting in damage to the internal light-emitting unit and dislocation of the film layer. The display panel is the main functional area of ​​the display device. Improving the anti-vibration and impact resistance of the display panel can effectively improve the display failure problem of the display device.

[0020] In order to solve the above problems, the inventors provided smooth curved surfaces on the surfaces of different layer structures inside the display panel to change the plana...

Abstract

The present invention relates to a display panel, include an array substrate, A light emitting unit provided on the array substrate and a pixel defining layer provided between adjacent light emittingunits, The light emitting unit comprises a first electrode layer (3), a light emitting layer (4) and a second electrode layer (5) arranged in a stacked order, the pixel defining layer and at least part of the surface of the light emitting unit being in a smooth curved surface, and the light emitting unit has a surface matching the smooth curved surface of the pixel defining layer. A display panelof the present invention and a display device having the same, A surface of a portion of a plurality of film layer including a pixel-defining lay and a corresponding light emitting unit is designed with a smooth curved surface, The contact area between the film layers can be enlarged, the adhesion effect between the film layers can be enhanced, and the external force can be better dispersed when the film layers are impacted by the external force, and the internal stress can be partially offset, so that the impact resistance of the panel and the device can be greatly enhanced.

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] Organic Light Emitting Diode (OLED) display is an organic electroluminescent device, which emits light by sandwiching an organic light-emitting material between a transparent anode and a metal reflective cathode, and applying a voltage to the organic light-emitting film layer. , can be used as a display device and a lighting device, and has the advantages of self-illumination, wide viewing angle, high contrast, low power consumption, and extremely high response speed. [0003] Compared with screens made of LCD and other materials, OLED screens have obvious advantages such as thinness and bendability, but on the other hand, the market also puts forward higher requirements for the performance of OLED products under external impact. At present, most of the layer structures in OLE...
