Embodiment 1
[0021] like figure 1 As shown, this embodiment provides a light-emitting device, including a light-emitting diode 10, the light-emitting device further includes a thermoluminescent layer 15 disposed on one side of the light-emitting diode 10, and the thermoluminescent layer 15 is used to absorb the light-emitting diode 10 during the light-emitting process. The heat generated in the light-emitting device emits light, so as to improve the light-emitting brightness of the light-emitting device.
[0022] The light emitting diode 10 may be an organic light emitting diode including a stacked cathode, an organic composite light emitting layer, and an anode. The organic light emitting diode may also selectively include an electron transport layer, a hole transport layer, etc., to improve the luminous efficiency. Of course, the light emitting diode 10 in the above-mentioned light emitting device may also be a horizontal inorganic micro light emitting diode or a vertical inorganic micr...
Embodiment 2
[0030] refer to figure 2 and image 3 , this embodiment provides a display substrate, including a plurality of sub-pixels, each sub-pixel includes a light-emitting device, at least one sub-pixel is a high-brightness sub-pixel, and the light-emitting device in the high-brightness sub-pixel is the light-emitting device in the above-mentioned embodiment 1 light-emitting device.
[0031] The light-emitting device provided in Example 1 will be applied to a display substrate, thereby reducing the temperature of the display substrate and improving the brightness of sub-pixel display. Each sub-pixel usually also includes a driving circuit for driving the light-emitting device, and the thermoluminescent layer 15 can also absorb the heat released by these driving circuits, thereby reducing the temperature of the driving circuit, which is beneficial to the stability of the system.
[0032] figure 2 Three light emitting devices are shown in . The light emitting diode 10 in the light...
Embodiment 3
[0050] This embodiment provides a display device including the above-mentioned display substrate.
[0051] Specifically, the display device can be an inorganic micro light-emitting diode (Micro-LED) display panel, an organic light-emitting diode (OLED) display panel, a mobile phone, a tablet computer, a TV, a monitor, a notebook computer, a digital photo frame, a navigator, etc. A product or part that displays functionality.
