Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an IR touch display,

The present invention relates to an IR touch display for preventing front plate projection.

Generally, a touch display device is an input device by which a user can touch a part of a display screen with a hand or another tool, thereby allowing a user to conduct a conversation process with the data processing system. The touch display device includes an infrared ray, a capacitance, and a resistive film, and an infrared (IR) touch display device uses infrared rays among them. The IR touch display device has the advantage that it can be used in a large size.

1 is in the form of a miniature IR touch display including a smart phone and the longitudinal cross section of the front plate 220 shown in FIG. 2 is provided in a large IR touch display It is a type of IR touch display that occurs with the weight of the front plate.

As shown in FIGS. 1, 3 and 5, when the external pressure 350 is applied to the front plate 120 on the side of the IR touch display device, ) Is generated. As described above, the front plate 320, which is warped, may protrude to the opposite region of the display 530 and may appear in the form of the front plate 520 shown in FIG. 5 under the influence of the elastic force when the external pressure 350 is removed .

자형으로 구비된 도 2에 외부압력(450)이 인가되면 도 4와 같이 전면판(420)의 휘어짐일 발생한다. 이와 같이, 휘어짐이 발생한 전면판(420)은 외부압력(450) 제거시 탄성력의 영향을 받아, 디스플레이(630)의 반대 영역으로 돌출되어, 도 6에 도시된 전면판(620) 형태로 나타날 수 있다.2, 4, and 6, the front plate 220 on the side of the IR touch display device

When the external pressure 450 is applied to FIG. 2, the front plate 420 is warped as shown in FIG. The front plate 420 having the curvature is protruded to the opposite region of the display 630 in the form of the front plate 620 shown in FIG. 6 under the influence of the elastic force when the external pressure 450 is removed have.

The front plates 520 and 620 of FIGS. 5 and 6 have a difference in angle of deflection, but can be cut off by the influence of the elastic force. Specifically, in this case, a part of the front plates 520 and 620 may protrude from the infrared region located between the light emitting devices 510 and 610 and the light receiving devices 511 and 611. Therefore, the infrared ray does not detect an object, and an error that the touch is not recognized occurs.

In addition, the conventional IR touch display device according to FIGS. 1 to 6 has frames 140, 240, 340, 440, 540 and 640 on both sides thereof, and the frame includes displays 130, 230, 330, 430, 530, 630).
