Display module and electronic device

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:

• a light-emitting member configured to emit visible light;
• a light-guide member disposed adjacent to the light-emitting member and configured to guide the visible light emitted by the light-emitting member to the display panel;
• and
• a back plate configured to accommodate the light-emitting member and the light-guide member and defining a plurality of through-holes;
• wherein the display module further comprises:
• a disinfection assembly, wherein the disinfection assembly is at least partially accommodated in the through-holes or disposed at one side of the back plate away from the display panel, wherein the disinfection assembly comprises a plurality of disinfection members, each of the plurality of disinfection members is correspondingly accommodated in one of the plurality of through-holes, and different disinfection members are accommodated in different through-holes, the plurality of disinfection members are disposed corresponding to the light-guide member, the disinfection assembly is configured to emit ultraviolet (UV) rays, the UV rays irradiate the display panel via the through-holes and the light-guide member, and the disinfection assembly is detachably connected to the back plate;
• wherein the light-guide member comprises:
• a first light-guide portion, wherein the first light-guide portion has a first light-incident surface and a light-exiting surface, the first light-incident surface is disposed corresponding to the light-emitting member, the visible light emitted by the light-emitting member is received via the first light-incident surface, the light-exiting surface is connected to the first light-incident surface in a bending manner, the light-exiting surface faces the display panel, and the visible light received via the first light-incident surface is emitted via the light-exiting surface to the display panel;
• and
• a plurality of second light-guide portions, wherein the plurality of second light-guide portions each is connected to the first light-guide portion in a bending manner, and each of the plurality of second light-guide portions is correspondingly accommodated in one of the through-holes, different second light-guide portions are accommodated in different through-holes;
• and the second light-guide portions each have a second light-incident surface away from the first light-guide portion, the UV rays emitted by the disinfection members are received via the second light-incident surface, the second light-guide portions each are configured to guide the UV rays received to the first light-guide portion, and the UV rays guided by the second light-guide portions are emitted to the display panel via the light-exiting surface;
• wherein,
• the processor is electrically connected to the disinfection assembly and is configured to control the disinfection assembly;
• the processor is further electrically connected to the light-emitting member and the display panel;
• and the processor is configured to control the light-emitting member to emit visible light to the display panel so as to display a prompt when the disinfection assembly operates.
