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 Art

[0002] Sub-millimeter LEDs (SMDs) refer to displays composed of LEDs with a die (chip) size ranging from 50 to 200 microns, placing them somewhere between micro LEDs and fine-pitch displays. Applications include SMD direct displays and SMD-backlit displays. Because SMD displays excel in energy consumption, color gamut, contrast, flexibility, and lifespan, and their manufacturing process is less complex than that of SMDs, making finished products relatively easy to manufacture, SMDs are expected to become a leading upgrade for LCD screens, competing with OLED displays in the consumer market.

[0003] Screens using sub-millimeter LED technology also boast advantages such as long lifespan and low burn-in resistance, and after mass production, their cost will be even lower than that of organic light-emitting diode displays. However, sub-millimeter LED technology also has its drawbacks. The more light-emitting units are integrated, the more partitions there are in the light-emitting units, the more signal lines are needed to electrically connect the light-emitting units, and the more ports are needed for signal transmission, which in turn increases the cost of the product.

Figure 1A As shown, the embodiment of the present application provides a light-emitting substrate 100, comprising: 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 are electrically connected to the signal lines 20; wherein 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, the first signal line 21 is electrically connected to the first light-emitting unit 31, and the second signal line 22 is electrically connected to the second light-emitting unit 32; the first signal line 21 is provided with a signal access terminal 211 and a first connection terminal 212, and the second signal line 22 is provided with a second connection terminal 221, the first connection terminal 212 is electrically connected to the second connection terminal 221, and the signal access terminal 211 is used to receive a signal.

[0035] The light-emitting substrate 100 provided in the present application reduces the number of signal access terminals 211 by electrically connecting the first signal line 21 and the second signal line 22 , thereby reducing signal transmission ports, reducing product production costs, and improving product competitiveness.

[0036] It should be noted that Figure 1A The figure only illustrates an example of the first signal line 21 being disposed to the left of the second signal line 22, that is, the signal is transmitted from left to right to the second signal line 22 via the signal access terminal 211 disposed at one end of the first signal line 21.

Specifically, the first light-emitting unit column 31 and the second light-emitting unit column 32 may also be arranged non-adjacently, and those skilled in the art may make adjustments as needed. This application does not make specific limitations here.

[0040] In the embodiment of the present application, the first signal line 21 is electrically connected to a plurality of second signal lines 22, and the number of second signal lines 22 is less than 20.

Each signal line 20 can control at least one column of light-emitting units 30, that is, 5 to 100 driver chips. Those skilled in the art can adjust the number of light-emitting devices 34 and the number of light-emitting units 30 connected in series on the signal line 20 as needed, and this application does not make specific limitations here.
