Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in Figure 1-2, a kind of touching display screen, including：
Screen assembly 12, the screen assembly 12 are fixed on inside heat-dissipating casing 2, and the screen assembly 12 includes photo-equilibrium
Component 10, it is used for the illuminating effect for balancing backlight 4, and the photo-equilibrium component 10 is located at backlight 4 and touch screen body 3
Between, the lower surface bonds of the backlight 4 have reflective membrane 6, and the upper surface of the touch screen body 3 is bonded with light polarizing film 9；
The lower surface of the heat-dissipating casing 2 is provided with radiating groove 8, and the opening of the heat-dissipating casing 2 is fixed with insured's panel
1。
Photomask 7, height and the phase of screen assembly 12 of photomask 7 are fitted with the side at the four sides of screen assembly 12
Together, shading treatment effectively can be carried out to the surrounding of screen assembly 12, avoids the edge of screen assembly 12 from causing light leak, improve
Display effect, the thickness of photomask 7 are no more than 0.5um, in order to be put into radiating after screen assembly 12 pastes photomask 7
In shell 2, the thickness of the screen assembly 12 is identical with the depth of inner cavity of heat-dissipating casing 2, and heat-dissipating casing 2 is box shaped, on the one hand may be used
