Description

[Technical field]

[0001] The present application relates to the field of display technology, and in particular to a light-emitting substrate and a display device. [Background technology]

[0002] Mini-LED was first offered by Epistar Corporation of Taiwan, and refers to a display consisting of light-emitting diodes with a die (chip) size of 50μm to 200μm, which is between micro light-emitting diodes and small pitch displays. Applications include displays that directly use mini light-emitting diodes and displays that use mini light-emitting diodes as backlights. Mini light-emitting diode displays are relatively superior in terms of power consumption, color gamut, contrast, flexibility, lifespan, etc., and the process difficulty is not as difficult as that of micro light-emitting diodes, making product manufacturing relatively easy. Therefore, mini light-emitting diodes are expected to become a major product that has evolved from liquid crystal displays and competes with organic light-emitting diode displays in the consumer market.

[0003] The screen using mini light-emitting diode technology also has the advantages of long life, less burn-in, etc., and the cost after mass production is lower than that of organic light-emitting diode display screen. Of course, mini light-emitting diodes also have disadvantages, since more light-emitting units are integrated, the more compartments of the light-emitting units, the more signal lines are electrically connected to the light-emitting units, and the corresponding number of ports for transmitting signals is also increased, which increases the product cost.

[0004] Therefore, how to reduce the signal transmission ports and lower the product production costs is a problem to be solved. Summary of the Invention [Problem to be solved by the invention]

[0031] Referring to FIG. 1A, FIG. 1A is a first structural schematic diagram of a light emitting substrate provided by an embodiment of the present application. FIG. 1B is a structural schematic diagram of a light emitting unit in the light emitting substrate provided by FIG. 1A. As shown in FIG. 1A, an embodiment of the present application provides a light emitting substrate 100, which includes a substrate 10, a plurality of signal lines 20, and a plurality of light emitting units 30. Specifically, the plurality of signal lines 20 are provided on the substrate 10. The plurality of light emitting units 30 are arranged in an array on the substrate 10, and the light emitting units 30 and the signal lines 20 are electrically connected. The plurality of signal lines 20 include at least a first signal line 21 and a second signal line 22, and the plurality of light emitting units 30 include a first light emitting unit 31 and a second light emitting unit 32, and the first signal line 21 and the first light emitting unit 31 are electrically connected, and the second signal line 22 and the second light emitting unit 32 are electrically connected. The first signal line 21 is provided with a signal access terminal 211 and a first connecting terminal 212, and the second signal line 22 is provided with a second connecting terminal 221, the first connecting terminal 212 and the second connecting terminal 221 are electrically connected, and the signal access terminal 211 is used for receiving signals.

[0032] The light emitting substrate 100 provided by the present application electrically connects the first signal line 21 and the second signal line 22, thereby reducing the number of signal access terminals 211 and signal transmission ports, thereby reducing product production costs and improving product competitiveness.

[0033] 1A, the first signal line 21 is provided on the left side of the second signal line 22, that is, the signal passes through the signal access terminal 211 provided at one end of the first signal line 21 and is transmitted from left to right to the second signal line 22. Specifically, the first signal line 21 may be provided on the right side of the second signal line 22, that is, the signal passes through the signal access terminal 211 provided at one end of the first signal line 21 and is transmitted from right to left to the second signal line 22. Here, the multiple signal lines 20 are provided in the same layer, but may be provided in different metal layers.

[0034] In the embodiment of the present application, the substrate 10 has a first side and a second side opposite to each other, the signal access terminal 211 is provided on the first side, and the first connecting terminal 212 and the second connecting terminal 221 are provided on the second side. Here, the substrate 10 may be a printed circuit board, a glass substrate 10, a flexible substrate 10, etc.

[0035] In the embodiment of the present application, the light emitting substrate further includes a connecting line 24, one end of the connecting line 24 is electrically connected to the first connecting terminal 212, and the other end of the connecting line 24 is electrically connected to the second connecting terminal 221.

[0036] In the embodiment of the present application, the plurality of light-emitting units 30 includes a first light-emitting unit row 31 and a second light-emitting unit row 32, the first signal line 21 and the first light-emitting unit row 31 are electrically connected, and the second signal line 22 and the second light-emitting unit row 32 are electrically connected, and preferably, the first light-emitting unit row 31 and the second light-emitting unit row 32 are adjacent to each other. This design is advantageous for sequentially transmitting data signals to the plurality of rows of light-emitting units 30 on the substrate 10, and avoids display problems caused by differences in resistance and charge amount due to time difference. Specifically, the first light-emitting unit row 31 and the second light-emitting unit row 32 do not need to be adjacent to each other, and those skilled in the art can adjust according to needs, but the present application is not specifically limited thereto.

Specifically, one driving chip 33 can control 1 to 20 light emitting element groups, and one light emitting element group may have 4 to 20 light emitting elements 34. Each signal line 20 can control at least one row of light emitting units 30, that is, 5 to 100 driving chips. Those skilled in the art can adjust the number of light emitting elements 34 and the number of light emitting units 30 connected in series to the signal line 20 as needed, but the present application is not specifically limited here.

[0039] In the present application, the signal line 20 refers to a data line that transmits a data signal. Specifically, by electrically connecting two, three or more rows of data lines, the number of data signal input ports inputted out of the plane to the light emitting substrate can be reduced to 1 / 2, 1 / 3, 1 / 4, etc., and the number of channels of the backlight control unit and the number of backlight control units can be reduced accordingly, thereby achieving the purpose of reducing the product cost.
