Abstract

The invention provides a backlight module and a display device. The backlight module comprises a substrate, a drive circuit layer arranged on the substrate, a protective layer arranged on the side, away from the substrate, of the drive circuit layer, a light reflecting layer arranged on the side, away from the drive circuit layer, of the protective layer, and a plurality of light emitting diode chips arranged on the side, away from the protective layer, of the light reflecting layer in an array mode. An uneven surface is arranged on the side, close to the reflective layer, of the protective layer, the adhesive force between the surface of the side, close to the reflective layer, of the protective layer and the reflective layer is increased, so that the risk of film separation of the reflective layer is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] Mini LED BLU (mini light emitting diode back light unit, Mini LED BLU) has gradually become the mainstream backlight technology due to its high brightness and local dimming function. By designing thin-film transistors to drive light-emitting diode chips on the driving circuit layer of the mini light-emitting diode backlight module, using thin-film transistors to realize active driving can greatly reduce the number of driving integrated circuit chips, and achieve more partition adjustments, thus giving the display The device brings better display effect. [0003] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of a mini LED backlight module in the prior art. The mini LED backlight module 1 is composed of a base substrate 11, a driving circuit layer 12 and a LED chip 13, and usually ...
