The utility model provides a kind of display screen anti-light leakage structure, its light leakage unit is arranged on container cavity surrounding, light leakage unit comprises titanium oxide powder part, by covering, the colour killing effect of light leakage unit, can effectively hide light guide plate surrounding, colour killing, thereby eliminate the generation of light leak situation, and this is to be fundamental purpose of the present utility model.
Technical solution adopted in the utility model is: a kind of display screen anti-light leakage structure, it comprises drain pan, light guide plate and light leakage unit, on this drain pan, be concaved with a container cavity, this light guide plate is fixedly installed in this container cavity, this light guide plate has upper surface, lower surface and lateral surface, wherein, this lateral surface is connected between this upper surface and this lower surface.
This light leakage unit is arranged on this container cavity surrounding, and this light leakage unit loop is located at this top surface edge surrounding of this light guide plate, this light leakage unit comprises titanium oxide powder part, and titanium oxide powder has rutile-type (Rutile R type) and two kinds of structures of anatase titanium dioxide (Anatase A type), wherein, rutile crystal compact structure, more stable, optical activity is little, thereby good weatherability, there is higher covering power, reducing power simultaneously.The utility model is by covering, the colour killing effect of this light leakage unit, can effectively hide this light guide plate surrounding, colour killing, thereby eliminate the generation of light leak situation.
This light leakage unit also comprises cell body, this cell body is arranged in this drain pan, this titanium oxide powder part is arranged in this cell body, in concrete enforcement, if this cell body adopts general linear pattern trough body structure, if in the time that this titanium oxide powder part is arranged in this cell body, user topples over screen so, there will be titanium oxide powder situation pockety, thereby affect light leakage effect, so in concrete enforcement, the utility model adopts following technical scheme, this cell body is spiral fashion hollow pipeline groove, can prevent because screen is toppled over the titanium oxide powder situation pockety that occurs by the structural design of spiral fashion hollow pipeline groove.
In concrete enforcement, this spiral fashion hollow pipeline groove comprises two horizontal cell bodies and two longitudinal cell bodies, wherein, article two, this longitudinal cell body is arranged on this drain pan both sides, article two, this horizontal cell body connection is arranged between two these longitudinal cell bodies, and two these horizontal cell bodies lay respectively at the upper and lower both sides of this drain pan.
Two ends up and down at this longitudinal cell body are respectively arranged with opening, this opening is arranged on the outside surface of this drain pan, thereby facilitate filler and later maintenance, in this opening, be provided with movable drain plug, in addition, in order further to fix the position of titanium oxide powder in this cell body, in this cell body, also convex with some separation ribs, by this separation rib, this titanium oxide powder part is isolated into some titanium dioxide latter ends.
The beneficial effects of the utility model are: this light leakage unit that the utility model provides is arranged on this container cavity surrounding, and this light leakage unit loop is located at this top surface edge surrounding of this light guide plate, this light leakage unit comprises titanium oxide powder part, and titanium oxide powder has rutile-type (Rutile R type) and two kinds of structures of anatase titanium dioxide (Anatase A type), wherein, rutile crystal compact structure, more stable, optical activity is little, thereby good weatherability, there is higher covering power, reducing power simultaneously.The utility model is by covering, the colour killing effect of this light leakage unit, can effectively hide this light guide plate surrounding, colour killing, thereby eliminate the generation of light leak situation.
