Problems solved by technology

In the infrared touch device of the above type, there is at least a dimension of the wall thickness of the profile between the filter strip and the front surface of the frame, and between the filter strip and the panel, which makes the front surface of the frame of the infrared touch device higher than the panel. The size, which is at least equal to the width of the filter bar plus twice the thickness of the profile, results in a thicker frame and a larger distance between the touch area and the front side of the panel, which is prone to false touches; in addition, due to the filter The light strip is located on the front side of the panel, and the part of the frame located on the front side of the panel must be provided with a structure for fixing the filter bar, so that the width of the frame is relatively large. On the premise of ensuring a sufficient touch area, the overall volume of the infrared touch device will be reduced. Larger, not easy to place

Abstract

The invention provides an infrared touch device and a profile. The device comprises an infrared board card, a light filtering part, a panel and an outer frame, the outer frame comprises a side frame part, a front frame part connected with the front end of the side frame part, and a rear frame part connected with the rear end of the side frame part. The side frame part comprises a panel accommodating groove for accommodating the edge part of the panel; a first side wall of the panel accommodating groove is formed on the rear side surface of the front frame part; the end surface of the free endof the front frame part is a first inclined surface; the first slope and the first side wall form an obtuse angle; the first inclined surface forms a first reflecting surface; or a first reflecting layer is arranged on the first inclined surface, a first reflecting surface is formed on the outer surface of the first reflecting layer, and at least part of infrared light emitted by the infrared board card sequentially penetrates through the light filtering part and the panel and is reflected by the first reflecting surface into light which is located on the front side of the panel and propagatesin the direction parallel to the front side surface of the panel; and the light filtering part is arranged on the rear side of the panel, so that the effects of a narrow frame and a thin frame are better achieved, and the risk that the light filtering part falls off is also reduced.

Description

technical field [0001] The invention relates to the technical field of infrared touch, in particular to an infrared touch device and a profile. Background technique [0002] Existing touch screens generally use infrared touch, and the infrared boards (PCBAs) of the current infrared touch solutions are designed to be placed horizontally or vertically, and the infrared touch circuit board components and the filter strips are fixed to the frame. Due to the layout of the infrared touch circuit board components and the filter strips, the frame will inevitably be wider and thicker. In the existing installation method, both the front side and the rear side of the filter strip need to be fixedly connected with the frame, which leads to a larger distance between the filter strip and the display screen, making the height of the touch area basically greater than 3mm, which means When the touch object is 3mm away from the front side of the display, the touch will respond, which is pron...
