Problems solved by technology

[0004] At present, when applying protective glue, multiple glue lines are sprayed on the wiring area at the same time through the glue spray valve, and the glue lines automatically level and solidify in the wiring area to form a protective film. The area of ​​the protective film is relatively large. In order to prevent the glue line from spreading to the display area, it is necessary to reserve a relatively large space at the edge of the display substrate to form the protective film, which is not conducive to realizing the narrow frame and no frame of the display device.

Abstract

The invention provides an OLED display substrate and a manufacturing method thereof and a display device, and belongs to the display technical field; the OLED display substrate comprises a display zone and a wiring zone; the manufacturing method comprises the following steps: at least forming a block structure between the wiring zone and the display zone; forming a rheological property organic material in the wiring zone, and enabling the rheological property organic material to form a protection film covering the wiring zone. The OLED display substrate and the manufacturing method thereof can realize narrow frame or frame-free designs of the display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display substrate, a manufacturing method thereof, and a display device. Background technique [0002] With the continuous advancement of science and technology, people's pursuit of beauty is becoming more and more intense, and the development and maturity of narrow frame or even frameless technology of display devices is imminent. [0003] Due to the product structure of the display device, in order to achieve a frameless design, the wiring area of ​​the display substrate (including COF (Chip On Film, chip-on-film) and FPC (Flexible Printed Circuit, flexible circuit board)) must be folded to the back of the display substrate. In order to increase the strength of the folded part, it is necessary to coat a layer of protective glue on the wiring area, and the protective glue can protect the folded part from being damaged by the folded part. [0004] At present, when appl...
