preparation example Construction

[0062] In order to solve the above technical problems, an embodiment of the present invention proposes a method for preparing a display substrate. The display substrate includes a plurality of pixel island regions, empty regions arranged between adjacent pixel island regions, and connecting bridge regions connecting adjacent pixel island regions. The preparation method of the display substrate includes:

[0063] Provide a hard substrate;

[0064] A first groove and a second groove are formed on one side of the substrate, the first groove corresponds to the pixel island region, and the second groove corresponds to the connection bridge region;

[0065] The display substrate is prepared on the side of the substrate where the first groove and the second groove are formed, the pixel island area is located in the first groove area, and the connection bridge area is located in In the second groove area, the empty area is located in an area outside the first groove and the second gr...

[0070] The first embodiment of the present invention provides a method for preparing a display substrate. The display substrate includes a plurality of pixel island regions, empty regions arranged between adjacent pixel island regions, and connecting bridge regions connecting adjacent pixel island regions. The island area is provided with a light-emitting unit, and the connecting lines between adjacent pixel islands are arranged in the connecting bridge area.

[0071] Figure 4 It is a schematic diagram showing the preparation method of the substrate according to the first embodiment of the present invention, such as Figure 4 As shown, the preparation method of the display substrate includes:

[0072] Provide a hard substrate;

[0073] A first groove 11 and a second groove 12 are formed on one side of the substrate, the first groove 11 corresponds to the pixel island region, the second groove 12 corresponds to the connection bridge region, and the first groove 11 and the se...

[0109] The second embodiment of the present invention provides a method for manufacturing a display substrate. Figure 8 It is a schematic diagram of the structure after forming the first groove and the second groove on one side of the substrate according to the second embodiment of the present invention. Different from the first embodiment, in this embodiment, the depth of the first groove 11 is w1, and the depth of the second groove 12 is w2. In this embodiment, w1<w2.

[0110] Figure 9 It is a schematic diagram of the structure after the base is formed on the substrate in the second embodiment of the present invention. In this embodiment, the base 20 is a flexible base, and the base 20 has a first thickness m1 corresponding to the first groove 11 , a second thickness m2 corresponding to the second groove 12 , and the first groove 11 and the second groove The area outside the groove 12 corresponds to the third thickness m3. Since w1m1>m3. In one embodiment, the first t...

Abstract

The invention discloses a display substrate, a preparation method thereof and a display device. The display substrate comprises multiple pixel island regions, empty regions and connecting bridge regions. The preparation method comprises the steps that a hard substrate is provided; first grooves and second grooves are formed in one side of the substrate, the first grooves correspond to the pixel island regions, and the second grooves correspond to the connecting bridge regions; the display substrate is prepared on the side, where the first grooves and the second grooves are formed, of the substrate, the pixel island regions are located in the first groove region, the connecting bridge regions are located in the second groove region, and the empty regions are located in a region except the first groove region and the second groove region; and the substrate and the display substrate are separated, so that the display substrate is obtained. In the process of preparing the display substrateby adopting the method, the segment gap between each empty region and other regions is greatly reduced, residues of an empty region film layer in a later process are avoided, badness caused by poor local disconnection is avoided, and the yield of the display substrate is increased.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate, a preparation method thereof, and a display device. Background technique [0002] Organic Electroluminescent Display (OLED / LED) has gradually become the mainstream in the display field due to its excellent performance such as low power consumption, high color saturation, wide viewing angle, thin thickness, and flexibility. It is used in terminal products such as smart phones, tablet computers, and TVs. Among them, flexible OLED / LED products are the most prominent, and gradually become the mainstream of OLED / LED displays because they can meet various special structures. [0003] With the development of flexible technology, flexible display panels gradually transition from bendable, foldable, to stretchable. With the gradual increase in the requirements for device flexibility, elastic flexible panels have entered everyone's field of vision. In the e...
