Abstract

The invention discloses a light-emitting structure, a backlight module, a display module and a display device. The light-emitting structure includes a circuit substrate, a plurality of light-emitting elements and a heat sink. The circuit substrate includes a first surface and a second surface arranged in sequence along the light-emitting direction of the light-emitting structure, and the circuit substrate also includes a light-transmitting substrate and a wiring structure located on one side of the light-transmitting substrate along the thickness direction; a plurality of light-emitting element arrays are arranged on On one of the first surface and the second surface of the circuit substrate, the light-emitting element is electrically connected to the wiring structure; the heat dissipation element is located on the first surface side of the circuit substrate, and the heat dissipation element is used to dissipate the heat generated by the light-emitting element. The light-emitting structure provided by the invention can solve the problem of high heat generation when the light-emitting element is in operation, and improve the light-emitting efficiency of the light-emitting structure.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light emitting structure, a backlight module, a display module and a display device. Background technique [0002] In order to realize the light-emitting display of the display device, the display device includes a light-emitting element, and the display of the display device is realized by emitting light from the light-emitting element. [0003] With the development of display devices, users have higher requirements on the luminous efficiency of display devices. In the process of display device lighting and display, if the structure of the display device is unreasonable, it will cause more heat in the light-emitting elements, which will affect the display. Luminous efficiency of the device. Contents of the invention [0004] The invention provides a light-emitting structure, a backlight module, a display module and a display device, which can solve the problem of high heat...
