Description

Filter structure for heavy-duty performance of infrared touch module

This creation is an infrared filter strip structure, especially for the filter strip structure applied to the infrared touch module.

Infrared touch technology is widely used in displays because of its high light transmission, sensing of any material, and its advantages for large sizes. The principle of the infrared touch display screen is to use a corresponding infrared emitter and receiver on the opposite side of the surface of the display screen, and the infrared emitter and the receiver form a dense infrared grid on the display screen surface, and the touch object is touched. A part of the infrared grid is blocked (for example, by a finger) to calculate the touch position.

Infrared touch display screens must use an infrared light transmission frame to ensure that the infrared receiving unit receives light infra-red to reduce ambient light interference. At present, there are two common ways to set the light-transmitting frame: the first one is an infrared touch display screen that uses an optical material that can transmit infrared light to block visible light; the second type uses an opaque material in the infrared touch. The infrared filter strip is encapsulated on the border of the control display screen. In order to reduce costs, most of the current methods use the second method. Infrared filter strips are made of plastic dyeing agents. There are two kinds of light filters. One is a high-pass filter strip that can transmit light with a wavelength greater than 850 nm or 940 nm. The other is a narrow-pass filter strip that can pass through a wavelength range of 925-955 nm. Light.

As shown in FIGS. 1A and 1B , a schematic view of a second embodiment includes a frame 10 having a display area 11 in the middle of the frame 10 . The display area 11 corresponds to a display module 12 and is displayed. The upper part of the module 12 is covered with a transparent plate 13. Two opposite sides of the frame 11 are provided with two sets of corresponding LED emitters 14 and receivers 15. The two sets of corresponding LED emitters 14 and receivers 15 are provided. On a first circuit board 16 and exposed on the upper surface of the transparent board 13, the first circuit board 16 is electrically coupled to a second circuit board 17, which is an LED circuit board, and the second circuit The board 17 is a main board. A filter strip 18 is packaged on the frame 10, and the filter strip 18 has a An upper protruding portion 181 and an extending portion 182 extending downward from an end of the upper protruding portion 181 and having a free end 1821 extending into the frame 10, and Located above the LED emitters 14 and receivers 15, the extensions 182 are shielded from the emitting surface of the LED emitters 14 and the receiving surface of the LED receivers 15 to isolate the effects of ambient light.

The free end 1821 of the extending portion 182 is adhered and fixed to the upper surface of the transparent plate 13 by a first adhesive strip 191. The lower surface of the transparent plate 13 is fixed to the second circuit board 17 by a second adhesive strip 192.

However, the above implementation has its problems. Since the second circuit board 17 and the transparent board 13 are fixed in an adhesive manner, when the infrared touch display screen needs to be replaced or repaired, the second circuit board 17 is removed. The separation from the transparent plate 13 causes damage to the wiring or electronic components of the second circuit board 17, and the second circuit board 17 cannot be reused and cannot be repaired.

Therefore, how to solve the aforementioned problems is that people in the field should actively solve the problem.

In order to achieve the above object, the present invention provides a filter bar structure with a rework efficiency of an infrared touch module, which is applied to a frame having a plurality of infrared emitters and an infrared receiver respectively disposed on a first circuit board. The infrared emitter and the receiver respectively have an emitting surface and a receiving surface, and the first circuit board is connected to a second circuit board, and the middle of the frame has a transparent plate is provided with a transparent plate, a transparent region of the transparent plate is exposed in the through hole, and a shielding region surrounds the outer side of the transparent region and corresponds to the boundary of the second circuit board and an outer peripheral side.
