Problems solved by technology

However, during the coating process of the buffer glue layer, the film thickness of the glue will be uneven, which will lead to the phenomenon of Newton rings in the display, or the problem of glue flushing due to the excessive volume of glue or excessive pressure will affect the display.
[0003] Therefore, in the coating process of the existing buffer glue layer, there are technical problems of poor display caused by uneven glue thickness and / or glue flushing problems.

Abstract

According to the OLED display device provided by the invention, at least one of the driving circuit layer and the light-emitting function layer is provided with the partition groove in the area between the retaining wall and the display area, so that when the buffer glue layer is pressed too much or the size of the glue is too large, the glue can be filled in the partition groove, the problem of glue flushing is avoided, and the service life of the OLED display device is prolonged. And when the buffer glue layer is not uniformly coated, the glue is diffused into the partition groove, so that the buffer glue layer forms a uniform film surface, and poor display caused by non-uniform glue thickness and / or glue flushing problems in the coating process of the buffer glue layer is avoided.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to an OLED display device. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light Emitting Diode) display devices are widely used due to their advantages of self-luminescence, wide color gamut, low power consumption, and flexible display. In order to improve the mechanical strength of the rigid substrate and improve the encapsulation effect of the existing OLED display device, a buffer layer is coated on the encapsulation layer. However, during the coating process of the buffer layer, the film thickness of the glue may not be uniform, resulting in a Newton's ring phenomenon during display, or because the glue volume is too large or the pressure is too high, which may lead to the problem of punching, which will affect the display. [0003] Therefore, in the coating process of the existing buffer adhesive layer, there are technical problems of...
