Abstract

The present invention provides a display substrate, a manufacturing method thereof, and a display device. The display substrate includes a base substrate, a driving circuit layer located on the base substrate, and a light-emitting unit located on the driving circuit layer; the display substrate also includes a heat dissipation assembly, and the heat dissipation assembly includes a heat dissipation structure, a heat dissipation channel and a heat conduction liquid, and the heat dissipation channel and the light emitting The cells are in contact, the heat-conducting liquid is accommodated in the heat-dissipating channel, and can circulate and flow along the heat-dissipating channel, and a part of the heat-dissipating structure extends into the heat-dissipating channel and is in contact with the heat-conducting liquid. The embodiments of the present invention can transmit and dissipate the heat generated by the light emitting unit through the heat dissipation component, can prevent the temperature of the light emitting unit from being too high, and help improve the reliability of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] With the development of display technology, the combination of QD (quantum dot, colloidal quantum dot) light-emitting material and blue light Micro LED (micro diode) is a very ideal quantum dot display structure. However, the use of Micro LED will generate a lot of heat, which may cause the failure of the QD material and affect the reliability of the display panel. SUMMARY OF THE INVENTION [0003] Embodiments of the present invention provide a display substrate, a method for fabricating the same, and a display device to solve the problem that heat generated during use may affect the reliability of a display panel. [0004] In a first aspect, an embodiment of the present invention provides a display substrate, including a base substrate, a driving circuit laye...
