Abstract
A touch type display device comprises a casing, a display screen and a touch screen, wherein an accommodating cavity is formed in the casing; the display screen is put in the accommodating cavity and fixed in the accommodating cavity; the casing surrounds the edge of the accommodating cavity to form a first step and a second step; the second step is closer to the center of the accommodating cavity than the first step and is located below the first step; the touch screen is fixed on the first step and covers the display screen; the touch type display device further comprises an elastic dustproof ring which is laid and fixed on the second step, one side of the dustproof ring is contacted with the second step, and the other opposite side is contacted with the display screen.
Description
Technical field
The present invention relates to touch-type display device.
Background technology
Touch-type display device comprises housing, display screen and touch-screen.Display screen and touch-screen are placed in housing, and touch-screen is placed in above display screen.Touch-screen and housing and all there is gap between display screen and touch-screen, dust can fall on display screen by gap, affects display effect.
Summary of the invention
In view of this, the invention provides a kind of touch-type display device, prevent dust from falling on the display screen of touch-type display device.
A kind of touch-type display device, comprise housing, display screen and touch-screen, housing is formed with host cavity, display screen is placed in host cavity and is fixed in host cavity, housing forms first step and second step around the edge of host cavity, second step is positioned at below first step than first step closer to the center of host cavity, touch-screen to be fixed on first step and to be covered by display screen, touch-type display device also comprises elastomeric wiper, elastomeric wiper is laid and is fixed on second step, the one side of dust ring contacts with second step, another contrary face contacts with touch-screen.
Dust is kept off outside host cavity by dust ring by above-mentioned touch-type display device, thus avoids dust to fall on display screen.

Main element symbol description
Lower embodiment will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Embodiment
Refer to Fig. 1 to Fig. 4, touch-type display device 10 comprises housing 12, display screen 14, touch-screen 16 and dust ring 18.
Housing 12 is formed with host cavity 20, and form first step 22 and second step 24 around the edge of host cavity 20, and second step 24 is positioned at below first step 22 closer to the center of host cavity 20 than first step 22.Display screen 14 is placed in host cavity 20 and is fixed in host cavity 20.In the present embodiment, housing 12 arranges multiple important actor 26 in host cavity 20, each important actor 26 is formed with a threaded hole 28, display screen 14 is formed with multiple through hole 30, and multiple screw 32 is screwed together in corresponding multiple threaded holes 28 through corresponding multiple through holes 30 and is fixed in host cavity 20 by display screen 14.
Touch-screen 16 to be fixed on first step 22 and to be covered by display screen 14.In the present embodiment, touch-screen 16 is fixed on first step 22 by the first pressure sensitive adhesive 34.The shape of the first pressure sensitive adhesive 34 is roughly consistent with first step 22 shape and be placed on first step 22, and touch-screen 16 is pressed on the first pressure sensitive adhesive 34, thus touch-screen 16 is adhered on first step 22 by the first pressure sensitive adhesive 34.
Dust ring 18 is laid and is fixed on second step 24, and dust ring 18 one side contacts with second step 24, and another contrary face contacts with touch-screen 16.In the present embodiment, dust ring 18 is fixed on second step 24 by the second pressure sensitive adhesive 36.The shape of the second pressure sensitive adhesive 36 is roughly consistent with second step 24 shape and be placed on second step 24, and touch-screen 16 is pressed on the second pressure sensitive adhesive 36, thus dust ring 18 is adhered on first step 22 by the second pressure sensitive adhesive 36.In the present embodiment, dust ring 18 is that foam is cotton.
Dust is kept off outside host cavity 20 by dust ring 18 by above-mentioned touch-type display device 10, thus avoids dust to fall on display screen 14.
