Abstract
Description
Technical Field
[0001] The utility model discloses a touch display device, in particular to a novel three-side frame infrared touch display device, belonging to the technical field of touch display devices. Background Art
[0002] Infrared touch technology is a technology that uses infrared sensors to achieve touch interaction. Its basic principle is to arrange a series of infrared transmitters and receivers on the touch surface. When there is no object touching the touch surface, the infrared transmitter will emit an infrared beam, which will be reflected by the surface and captured by the receiver; when an object touches the surface, the touched area will block the reflection of the infrared beam, resulting in a decrease in the amount of light received by the receiver. By detecting the change in the amount of light received by the receiver, the system can determine the touch position and touch action. Infrared touch technology is widely used in various devices, including smartphones, tablets, kiosks, interactive displays, gaming devices, etc.
[0003] Please refer to the attached Figure 1 and attached Figure 2 Infrared touch display devices in the prior art are mostly double-sided or four-sided structures. The main disadvantage of double-sided structure products is that they are limited by the structure, the edge accuracy is poor, and the touch experience is not good. Although the four-sided structure products can solve the problem of poor edge accuracy, since they have infrared transmitting / receiving LEDs on all four sides, the structure at the lower edge is prone to dust accumulation during actual use, and it is difficult to meet the waterproof requirements. Summary of the invention
[0004] In view of the above-mentioned shortcomings of the infrared touch display devices in the prior art, such as poor accuracy or easy dust accumulation, the utility model provides a novel three-sided frame infrared touch display device, which can effectively balance the problems of poor accuracy and easy dust accumulation of the device by setting infrared elements on three sides.
[0005] The technical solution adopted by the utility model to solve its technical problems is: a novel infrared touch display device with three-sided outer frame, the infrared touch display device comprises an infrared transmitting end, an infrared receiving end and an infrared transmitting and receiving end, the infrared transmitting end and the infrared receiving end are respectively arranged on the left and right sides of the infrared touch display device, an infrared transmitting LED is arranged on the infrared transmitting end, an infrared receiving LED is arranged on the infrared receiving end, the infrared transmitting and receiving end is arranged above the infrared touch display device, and an infrared transmitting LED and an infrared receiving LED are arranged on the infrared transmitting and receiving end.
[0006] A novel three-sided frame infrared touch display device comprises three infrared transmitting and receiving ends. The infrared transmitting LED and the infrared receiving LED on the infrared transmitting and receiving ends are arranged at intervals from each other. The three infrared transmitting and receiving ends are respectively arranged on the left side, the right side and the top of the infrared touch display device. A reflective object is arranged at the bottom of the infrared touch display device. The three infrared transmitting and receiving ends are connected to each other in sequence through connecting lines.
[0007] The technical solution adopted by the utility model to solve its technical problems further includes:
[0008] The infrared transmitting end, the infrared transmitting receiving end and the infrared receiving end are connected to each other through a connecting line.
[0009] The connecting line adopts FFC line.
[0010] The infrared transmitting end is arranged on the left side of the infrared touch display device, and the infrared receiving end is arranged on the right side of the infrared touch display device, or the infrared transmitting end is arranged on the right side of the infrared touch display device, and the infrared receiving end is arranged on the left side of the infrared touch display device.
[0011] The infrared transmitting LED and the infrared receiving LED on the infrared transmitting and receiving end are arranged at intervals.
[0012] A reflective object is arranged on the side opposite to the infrared transmitting and receiving end.
[0013] The reflective object is a reflective strip, a light-guiding strip or a metal reflective material.
[0014] The beneficial effects of the utility model are: because the utility model has no lower frame, it can be waterproof and chalk dust proof, and the cost of the entire design scheme of four sides will be greatly reduced. Compared with the double-sided structure product, the utility model has a cross-axis light at the upper end, which solves the edge effect problem of the double-sided structure product and reduces the black edge silk screen problem.

[0026] In this embodiment, a reflective object 7 is arranged on the opposite side of the infrared transmitting and receiving end 1, that is, a reflective object 7 is arranged at the bottom of the infrared touch display device. The light emitted by the infrared transmitting LED 2 is reflected by the reflective object 7 and then received by the infrared receiving LED 3.
