Figure, Figure 10 are the corresponding side view of Fig. 9, and display panel 1 includes the array substrate 9B and color membrane substrates 10B being oppositely arranged, array
Liquid crystal layer 11B is provided between substrate 9B and color membrane substrates 10B.Ultraviolet light is provided in frame region 3, color membrane substrates 10B
Light source 8, ultraviolet light source 8 are located at side of the color membrane substrates 10B far from array substrate 9B；Color membrane substrates 10B is far from array substrate
The side of 9B is provided with touch control electrode 20 and the touching signals line 7 with the setting of 5 same layer of ultraviolet light source connecting line.
Ultraviolet light source 8 is located at side of the color membrane substrates 10B far from array substrate 9B, that is, ultraviolet light source 8 is set
In the light-emitting surface of display panel 1, at this point, the ultraviolet light irradiated can greatly irradiate display screen, thus real
Now display screen is greatly sterilized.Also, by ultraviolet light source connecting line 5 and the original touching signals line 7 of display panel 1
Same layer setting, ultraviolet light source connecting line 5 and touching signals line 7 are using the formation of same technique, without additional structure
Figure technique, simplifies production process, reduces the production cost.
Further, referring again to Fig. 9, frame region 3 includes being located at display area 2 in a first direction relatively
The the first frame region 16B and the second frame region 17B of two sides, ultraviolet light source 8 are located at the first frame region 16B and/or
Two frame region 17B.
Specifically, when ultraviolet light source 8 is located at the first frame region 16B or the second frame region 17B, ultraviolet light source
After 8 open, ultraviolet light is pointed into the other side from the side of display screen, to realize the disinfection to entire display screen.
Specifically, when ultraviolet light source 8 is located at the first frame region 16B and the second frame region 17B, it is ultraviolet utilizing
When linear light source 8 carries out disinfection to display screen, ultraviolet light is irradiated from two side of display screen to centre simultaneously, is shone display screen different zones
That penetrates is more comprehensive, improves the sterilization effect to display screen entirety.Moreover it is possible to enable the first frame region 16B and second
The width of frame region 17B tends to balance, and optimizes the appearance of display device.
Optionally, as shown in figure 11, Figure 11 is the structural schematic diagram of ultraviolet light source provided by the embodiment of the present invention, purple
Outer linear light source 8 is located at the light emission side of display panel 1；Ultraviolet light source 8 includes light exit side 22, the light direction court of exit end 22
To the light-emitting surface of display panel 1, in the direction perpendicular to 1 place plane of display panel, the height and position of light exit side 22 is super
The height and position of the light-emitting surface of display panel 1 out, with guarantee ultraviolet light source 8 project ultraviolet light it is as much as possible be irradiated to it is aobvious
In display screen, reach better Disinfection Effect.
Optionally, referring again to Figure 11, ultraviolet light source 8 is located at the light emission side of display panel 1；Display panel 1 is separate
The side of ultraviolet light source 8 is provided with heat dissipating layer 23, in the direction perpendicular to 1 place plane of display panel, ultraviolet light source 8
It is overlapping with heat dissipating layer 23.When ultraviolet light source 8 carries out disinfection to display screen, the heat that ultraviolet light source 8 distributes can be via heat dissipation
Layer 23 is dissipated into outside display panel 1, is avoided heat from accumulating in inside display panel 1, is caused to damage to the device in display panel 1
Wound.
Optionally, ultraviolet light source 8 can also be equipped with reflection layer towards the side of light-emitting surface, what ultraviolet light source 8 projected
After ultraviolet light is reflected via reflection layer, display screen can be further exposed to, reinforces the sterilization effect of display screen.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent substitution, improvement and etc. done be should be included within the scope of the present invention.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
