Problems solved by technology

like figure 1 As shown, the display panel includes a switch array layer 12, an organic layer 13, and an encapsulation layer 14 sequentially arranged on a base substrate 11. Generally, an OLED is encapsulated by stacking an organic layer and an inorganic layer (that is, the structure of the encapsulation layer includes inorganic layer and organic layer), but the organic layer has a certain degree of fluidity. In order to prevent the overflow of the organic layer, it is necessary to set a retaining wall structure 15 at the edge of the encapsulation layer 14. Since the retaining wall structure 15 is located in the non-display area, it will be to a certain extent Increased the size of the bezel of the display panel

Abstract

The invention provides a display panel and a display device. The display panel comprises a display area, wherein the display area comprises light emitting units arranged in an array mode; the displayarea comprises a middle area and an edge area located on the periphery; a plurality of blocking parts are arranged in the light emitting gap area in at least one edge area; a plurality of first gaps are formed in the light emitting gap area in the middle area; and the contact area of each blocking part and a packaging layer of the display panel is larger than the contact area of each first gap andthe packaging layer, wherein the light emitting gap area is a gap between two adjacent lines of light emitting units or a gap between two adjacent columns of light emitting units. By virtue of the display panel and the display device, the frame of the display panel can be reduced.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a display panel and an electronic device. 【Background technique】 [0002] The organic light emitting diode (OLED) display panel has many excellent characteristics such as self-illumination, low energy consumption, wide viewing angle, rich colors, fast response, and the ability to prepare flexible screens, and has become a promising next-generation display technology. [0003] However, as the demand for a full screen increases, reducing the area of ​​the edge region (non-display region) has become a research hotspot. Such as figure 1 As shown, the display panel includes a switch array layer 12, an organic layer 13, and an encapsulation layer 14 sequentially arranged on a base substrate 11. Generally, an OLED is encapsulated by stacking an organic layer and an inorganic layer (that is, the structure of the encapsulation layer includes inorganic layer and organic layer), but th...
