Background

With the development of advanced science and technology society, the position of information spreading in our life and production has become more and more important, and along with this, various information media machines have come into existence, and in order to increase the convenience of human-computer interaction, touch equipment begins to appear on the media machine, and infrared touch equipment is one of them. At present, the television and the display screen are updated more and more quickly, the size of the frame of the display screen is smaller and smaller, and most infrared touch frames need to have certain width to meet the requirements of structure and electronics. Therefore, the ultra-narrow edge infrared touch frame is better suitable for the current novel ultra-narrow edge display screen.

The existing infrared touch frame display screen is matched in a manner shown in fig. 2, a PCB board with an LED lamp is fixed in the infrared touch frame, the infrared touch frame is attached to the surface of the display screen through double-sided adhesive or other means, the distance from the frame of the display screen to the v.a area of the display area is D, and the average value of the size of D is 10mm at present, so that the width D of the touch frame is less than D, and the LED lamp and the PCB board are placed in parallel, so the average value of the width D of the touch frame of the structure must be about 10 mm.

Another mode that current infrared touch frame display screen was supporting is shown in fig. 3, structurally makes LED lamp and PCB board adopt perpendicular mode to place, though can compatible narrow frame's display screen, but infrared touch frame self's frame width is very big, and the main reason is the thickness of LED lamp must remain, and PCB plate thickness, section bar frame wall thickness, various thickness stack are in the same place simultaneously for touch frame appearance whole width d can't further compress.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an infrared touch frame structure for overcoming the defect that above-mentioned prior art exists.

The purpose of the utility model can be realized through the following technical scheme:

the utility model provides an infrared touch frame structure, installs around the display screen, includes framework, LED lamp and PCB board, inside LED lamp and PCB board electric connection just arranged the framework in, the display screen includes body and protection glass, the LED lamp just arranges protection glass's both sides respectively with the PCB board is vertical.

The LED lamp is connected with the PCB through a wire.

The LED lamp laminating cover glass, PCB board laminating body.

The PCB is perpendicular to the protective glass, and the optical axis of the LED lamp is parallel to the protective glass.

The body be fixed with the card body, the framework passes through the card body and body joint.

The frame body is bonded with the body.

The LED lamp comprises a transmitting LED lamp and a receiving LED lamp, wherein the transmitting LED lamp and the receiving LED lamp are arranged oppositely.

The frame body is a metal frame body.

Compared with the prior art, the utility model has the advantages of it is following:

(1) the LED lamp and the PCB are vertically arranged and are respectively arranged on two sides of the protective glass, so that the LED lamp and the PCB are separated, the width of the superposition direction is increased when the LED lamp and the PCB are superposed together, the display screen is suitable for the ultra-narrow-edge display screen, the purpose of saving space is achieved, and a better visual effect is achieved.

(2) The LED lamp is connected with the PCB through the lead, and the lead has flexibility, can be bent and is easy to adapt to the structures of different display screens.

(3) LED lamp laminating protective glass, PCB board laminating body can further compress the width of infrared touch frame.

(4) The PCB is perpendicular to the protective glass, and the optical axis of the LED lamp is parallel to the protective glass, so that the width of the infrared touch frame can be further compressed.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Examples

The embodiment provides an infrared touch frame structure, as shown in fig. 3, the infrared touch frame structure is installed around a display screen and comprises a frame body 1, an LED lamp 3 and a PCB 2, the LED lamp 3 and the PCB 2 are electrically connected and arranged inside the frame body 1, the display screen comprises a body 4 and a protective glass 5, the average value of the frame size D of the display screen is about 5mm, even the numerical value is smaller, the LED lamp 3 and the PCB 2 are vertically arranged and respectively arranged on two sides of the protective glass 5; this structure makes LED lamp and PCB board separation, avoids LED lamp and PCB board coincide to increase the width of coincide direction together, adapts to super narrow limit display screen, reaches the purpose of saving space, and has better visual effect.

Specifically, the LED lamp 3 is connected with the PCB 2 through a lead; the conducting wire has flexibility, can be bent, and is easy to adapt to the structures of different display screens; the metal pins of the LED lamp 3 can be lengthened to realize connection.
