Abstract

The invention provides a display panel and a display device thereof, which relate to the field of display technology and are used for preventing the display area of ​​the display panel from being damaged and improving the yield rate of the display panel. The display panel includes a first substrate, the first substrate includes a packaging area; a second substrate opposite to the first substrate; a packaging metal layer, a plurality of first through holes are arranged on the packaging metal layer, and the first through holes are located in the first Inside the packaging metal part and the second packaging metal part; the packaging metal layer is also provided with a plurality of second through holes, and the second through holes are located in the corner packaging metal part; in the packaging area of ​​the same area, the second through holes occupy the corner packaging metal The area percentage of the first through hole is P3, the area percentage of the first through hole to the first package metal part is P1, P3>P1; the encapsulation glue, the encapsulation glue is filled in the first through hole and the second through hole, and passes through the first through hole The hole and the second via bond the first substrate and the second substrate together. The above display panel is applicable to a display device.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device thereof. 【Background technique】 [0002] Compared with many display panels, the OLED (Organic Light-Emitting Diode, hereinafter referred to as OLED) display panel has many advantages such as active light emission, high contrast ratio, and no viewing angle limitation. OLED display panels are not only lighter and thinner in size, but also lower in power consumption than other display panels, which helps to improve the battery life of display devices. Therefore, OLED display panels are widely used in the field of display technology and will become the future of display devices. mainstream products. [0003] At present, glass welding technology can be used for OLED packaging, that is, using laser to irradiate glass sealant (containing laser-absorbing pigments) to bond the upper and lower substrates. [0004] However, during the encaps...
