Embodiment 1
[0026] Embodiment 1 of the present invention proposes an OLED display panel, which includes:
[0027] Such as Figure 1-Figure 5 As shown, the substrate 1, the protective layer 3 and the display function layer 2, the protective layer 2 is stacked on the substrate 1, and the protective layer 3 includes a first area and a second area surrounding the first area; the display function layer 2, the display function The layer 2 is arranged on the protected layer 3 and corresponds to the position of the first area; wherein, an annular groove 4 is arranged on the surface of the second area, and the annular groove 4 is arranged around the outside of the first area, and the annular groove 4 The bottom of the groove is pointed, which is used to prevent the second area from forming a gap that can extend to the first area.
[0028] Wherein, the substrate 1 is the base of the display panel and the supporting part of the device. The substrate 1 can be a flexible substrate in the prior art. F...
Embodiment 2
[0039] Such as Figure 6 As shown, Embodiment 2 of the present invention proposes a method for manufacturing an OLED display panel, the method comprising:
[0040] S1: Form a protective layer 3 on a substrate 1 .
[0041] Specifically, the protective layer 3 can completely cover the substrate 1 . The substrate 1 can be any substrate 1 in the prior art, for example, it can be a flexible substrate 1, and the material of the flexible substrate 1 can be a polymer substrate, an ultra-thin glass substrate, a stainless steel substrate, etc., which will not be described in detail here. limit.
[0042] S2: Setting display function 2 on the first area of protective layer 3 .
[0043] S3: Prepare the ring groove 4 on the second region of the protective layer 3 .
[0044] Specifically, the protective layer 3 and the display function 2 are successively formed on the substrate 1. The display function 2 includes organic materials and electrodes constituting the OLED device, etc., and t...
Embodiment 3
[0048] Embodiment 3 of the present invention proposes a display device, which includes:
[0049] A display device body and the aforementioned OLED display panel.
[0050] The display device body can be an electronic device with a display function such as a mobile phone, a computer, and a television in the prior art, and the above-mentioned OLED display panel is used.
[0051] The embodiment of the present invention proposes a display device. By setting the ring groove 4 in the second area of the protective layer and setting the groove bottom of the ring groove 4 as a sharp angle, when the edge of the display device body is hit, the collision along the The tip of the groove bottom of the ring groove 4 produces a gap perpendicular to the direction of the substrate 1, the gap will not extend to the packaging area, and the second area is a non-luminous area, which will not affect the display function of the display device body, and solves the problem of the prior art In this ca...
