Abstract

Provided are a display module and an electronic device. The display module includes a display panel and a backlight module stacked with the display panel. The backlight module includes a light-emitting member, a light-guide member, and a back plate. The light-emitting member is configured to emit visible light. The light-guide member is disposed adjacent to the light-emitting member and configured to guide the visible light to the display panel. The back plate is configured to accommodate the light-emitting member and the light-guide member and defines a through-hole. The display module further includes a disinfection assembly. The disinfection assembly is at least partially accommodated in the through-hole or disposed at one side of the back plate away from the display panel, the disinfection assembly is configured to emit UV rays, the UV rays irradiate the display panel via the through-hole, and the disinfection assembly is detachably connected to the back plate.

3. The display module of claim 2 , wherein the carrier comprises a first mating portion, and the first mating portion is misaligned with the plurality of disinfection members; the back plate comprises a second mating portion, and the second mating portion is disposed corresponding to the first mating portion; and the disinfection assembly further comprises a connector detachably connecting to the first mating part and the second mating part.

4. The display module of claim 3 , wherein the first mating portion is disposed to avoid the plurality of disinfection members, and the second mating portion is disposed to avoid the plurality of through-holes.

5. The display module of claim 2 , wherein the disinfection assembly further comprises:
a shield disposed at one side of the carrier away from the display panel, the shield being detachably connected to the back plate, and the shield covering the carrier.

6. The display module of claim 1 , wherein the first light-guide portion has two long sides opposite to each other and two short sides opposite to each other, the disinfection assembly is disposed adjacent to one of the two long sides, and the light-emitting member is disposed adjacent to the other one of the two long sides.

7. The display module of claim 1 , wherein in a direction perpendicular to the light-exiting surface, the first light-incident surface and the second light-incident surface are located at different sides of the first light-guide portion.

8. The display module of claim 1 , wherein in each of the through-holes, the second light-guide portion is spaced apart from the disinfection member, and a distance d between the second light-guide portion and the disinfection member satisfies: 0<d≤0.3 mm.

9. An electronic device comprising a processor and a display module, wherein the display module comprises a display panel and a backlight module stacked with the display panel, and the backlight module comprises:
