Description

Touch display screen with air guide groove

Technical Field

The utility model belongs to the technical field of touch display screen, concretely relates to touch display screen in area air guide groove.

Background

When the digital display screen of big lamp chamber is in production, because there is the problem of expend with heat and contract with cold in the gas in lamp chamber, lead to the atmospheric pressure inconsistent inside and outside the lamp chamber, can arouse that the touch facial mask on surface sinks, and the hard gas ITO material of back of sinking and preceding control face lid can not completely be laminated together, lead to the touch inefficacy. When the external temperature is higher and the internal temperature is lower, the gas in the closed space contracts, the pressure is reduced, the external air pressure is higher, and meanwhile, because the area of the lamp cavity is large, the diaphragm cannot be well supported, so that the display area is concave, and the touch key area cannot be completely attached to the front control surface cover, so that the touch failure is caused.

SUMMERY OF THE UTILITY MODEL

The utility model provides a technical problem: the invention provides a touch display screen with an air guide groove, which can balance the air pressure inside a lamp cavity and outside, prevent the lamp cavity from collapsing and prevent touch failure.

The technical scheme is as follows: in order to solve the technical problem, the utility model discloses a technical scheme as follows:

the utility model provides a take touch display screen in air guide groove, the display screen includes PET membrane, ITO film and glues the face, the ITO film is attached to the lower surface of PET membrane, glue the face and attach to the lower surface of ITO film glue and be provided with the air guide groove on the face.

Preferably, the display screen, the plastic shell and the PCB are enclosed to form a closed display lamp cavity, the air guide grooves of the display lamp cavities are communicated with the air passages among the display lamp cavities, the air passages are communicated with the outside to form convection, and the air pressure inside the display lamp cavities and the air pressure outside the display lamp cavities are balanced.

Preferably, the plurality of air guide grooves of each display screen are arranged in parallel and are uniformly spaced.

Preferably, the air guide grooves are arranged transversely and vertically across the rubber surface.

Preferably, the tail end of the air channel is communicated with the outside through a small hole formed in the edge of the display panel, and the length of the air channel between the small hole and the display lamp cavity is 3-5 mm.

Preferably, the PET film and the ITO film and the adhesive surface are bonded through water adhesive.

Has the advantages that: compared with the prior art, the utility model has the advantages of it is following:

the utility model discloses a touch display screen of air guide groove is provided with the air guide groove on gluing the face to set up the air flue between the display lamp chamber, the air flue makes the display lamp chamber gaseous connection of whole display screen be in the same place, also links together with the external world simultaneously, can guarantee like this that the display screen lamp wall is interior to keep circulating with external gas, makes the inside and outside pressure of lamp chamber keep unanimous, prevents that the display screen in display lamp chamber from collapsing. Meanwhile, because the area of the glue groove is small, the moisture permeation is very limited, and the moisture-proof function of the whole display screen can be ensured.

Detailed Description

The present invention will be further illustrated by the following specific examples, which are carried out on the premise of the technical scheme of the present invention, and it should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1-4, the touch display screen with the air guide groove of the application comprises a display screen 1, a plastic shell 11 and a PCB 6, wherein the display screen 1, the plastic shell 11 and the PCB 6 enclose to form a closed display lamp cavity 7, the display screen 1 comprises a PET film 2, an ITO film 3 and an adhesive surface 4, the ITO film 3 is attached to the lower surface of the PET film 2, the adhesive surface 4 is attached to the lower surface of the ITO film 3, and the air guide groove 5 is arranged on the adhesive surface 4.

Be provided with a plurality of display lamp chambeies 7 on every display panel 9, in order to make each display lamp chamber 7 all communicate with the external world, between each display lamp chamber 7, and set up air flue 8 between display lamp chamber 7 and the display panel 9 edge near display panel 9 side, air flue 8 is integrated into one piece with air guide groove 5, be the extension of air guide groove 5 in the display lamp chamber 7 outside to display lamp chamber 7, air guide groove 5 that shows lamp chamber 7 passes through air flue 8 and external intercommunication, form gaseous convection current, the inside atmospheric pressure with the external world of balanced display lamp chamber 7.

The air guide grooves 5 in each display lamp cavity 7 can be provided with a plurality of air guide grooves 5, and the air guide grooves 5 of each display screen 1 are arranged in parallel and are uniformly spaced. Or the air guide grooves 5 in the display lamp cavity 7 are arranged transversely and vertically in a cross way on the rubber surface 4 and can be communicated in the transverse and vertical directions.
