Abstract

A display substrate comprises a silicon-based substrate and a first color film layer arranged on the silicon-based substrate, the silicon-based substrate is provided with a display area and a peripheral area located on the periphery of the display area, and the peripheral area comprises a binding area located on one side of the display area; the first color film layer is located in the peripheral area, the first color film layer comprises at least one color adhesive layer, each color adhesive layer is provided with a hollow structure, the first color film layer comprises at least one first alignment mark, and the first alignment mark is formed by the hollow structure of at least one color adhesive layer; and the orthographic projection of the first alignment mark on the silicon-based substrate is located between the display area and the binding area in the second direction.

Description

technical field [0001] Embodiments of the present disclosure relate to but are not limited to the field of display technology, especially a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Micro-OLED (Micro Organic Light-Emitting Diode) is a micro-display developed in recent years, and silicon-based organic light-emitting diode (OLED, Organic Light-Emitting Diode) is one of them. In the manufacturing process of silicon-based OLED display products, it is often necessary to bind and connect the display substrate and the flexible printed circuit board, but there is a problem of difficult alignment between the display substrate and the flexible printed circuit board, which greatly affects the yield of the product . Contents of the invention [0003] The following is an overview of the topics described in detail in this article. This summary is not intended to limit the scope of the claims. [0004] Embodiments of the pre...
