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...

Abstract

The invention discloses an OLED display panel, a manufacturing method thereof and a display device, and relates to the technical field of OLED display to solve the problem in the prior art that when the edge of the OLED display panel is subjected to external collision, a crack extending to a packaging region corresponding to a display region is likely to be generated and thus affects a packaging effect. The OLED display panel includes: a substrate; a protective layer stacked on the substrate and including a first region and a second region surrounding the first region; and a display functionallayer disposed on the protective layer and corresponding to the position of the first region, wherein the surface of the second region is provided with an annular groove, the annular groove surroundsthe first region, and the bottom of the annular groove is in a sharp corner shape to prevent the second region from creating a crack extending to the first region.

Description

technical field [0001] The invention relates to the field of OLED display technology, in particular to an OLED display panel, a manufacturing method thereof, and a display device. Background technique [0002] The Chinese name of OLED is "organic electroluminescence display", also known as "organic electroluminescence display". It has many advantages such as a wide operating temperature range, and is called a "dream display" by the industry, representing the current development direction of display technology. [0003] The flexible OLED display has the characteristics of low power consumption and bendability, which has a profound impact on the application of portable electronic devices and wearable electronic devices. The use of plastic instead of glass to make the display makes the display more durable and lighter. The flexible OLED display adopts thin-film encapsulation (TFE), which prolongs the water vapor intrusion path through alternating inorganic and organic multi-la...
