Abstract

The invention relates to the technical field of a display device and particularly relates to a display panel, a preparation method thereof and the display device. The display panel comprises a base plate, wherein the base plate comprises a display area and a non-display area. A plurality of organic electroluminescent structures are set in the display area. At least one blocking dam and a punchingarea are set in the non-display area. The blocking dam is set between the display area and the punching area. At least one sunken part is set on a side wall of the blocking dam. The sunken part is setat one side of the blocking dam adjacent to the punching area. According to the display panel, the preparation method thereof and the display device, the at least one sunken part is set on the side wall of the blocking dam, an organic material deposited on the side wall of the blocking dam when evaporation is carried out is reduced, and packaging failure resulting from particle fall-off due to heat radiation when laser punching is carried out is avoided.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the advancement of science and technology, digital display devices such as smartphones and tablet computers are widely used, and display screens are indispensable human communication interfaces in these display devices. Such as organic light-emitting (English full name is OrgnicLight-Emitting Diode, referred to as OLED) display panel, which has the advantages of self-illumination, energy saving, bendability, good flexibility, etc., and the display device for realizing display does not require a backlight source and has The characteristics of fast response and good display effect have attracted the attention of users and are widely used in terminal products such as smart phones and tablet computers. [0003] With the rapid development of electronic devices, users hav...
