Embodiment Construction

[0049] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0050] As an aspect of the present invention, a display substrate for use in an organic light emitting (OLED) device is provided. Such as Figure 4 As shown, the display substrate includes a display area 11 and a non-display area surrounding the display area 11. The display area 11 has multiple sides, and rounded corners are formed between two adjacent sides, as shown in Figure 4 Among them, the shape of the display area 11 is a rounded rectangle; the non-display area includes a frame portion 121 opposite to the sides of the display area 11 and a corner portion 122 opposite to the rounded corners one by one, that is, the corner portion The side of 122 facing ...

Abstract

The invention provides a display substrate. The display substrate comprises a display area and a non-display area surrounding the display area, at least one limiting mark set is arranged in the non-display area, the display area has many sides, and a round chamfer is formed between two adjacent sides; the non-display area comprises border parts and corner parts, wherein the border parts correspondto the sides of the display area one to one, and the corner parts correspond to the round chamfers one to one; the limiting mark sets are located on the corner parts. Accordingly, the invention further provides an organic light-emitting device, a film layer evaporation detection method thereof and a display device. Poor display can be avoided, and the accuracy of film layer evaporation detectionis improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, an organic light-emitting device, a method for detecting film vapor deposition of an organic light-emitting device, and a display device. Background technique [0002] Each pixel area of ​​an organic electroluminescence (Organic Light-Emitting Device, OLED) display device is provided with a light-emitting unit. The light-emitting unit includes multiple organic film layers, and each organic film layer is formed by an evaporation process. In order to detect whether the evaporation position of each organic film layer is shifted, an alignment area is usually provided in an area other than the display area. figure 1 It is a schematic diagram of the first setting position of the alignment area in the prior art, where the alignment area 20 is set on the display substrate and located on both sides of the display area 11; figure 2 It is a schematic diagram of the s...
