Description

FIELD OF THE INVENTION [0001] The present invention relates to an infrared touch screen filter,

The present invention relates to an infrared touch screen filter.

Among the methods of constructing a touch screen in recent years, a method of recognizing coordinates in a touch screen by using visible light or infrared rays, that is, an IR method, has been used. As an example of this IR scheme, the IR matrix method is a touch screen method using an infrared IR, and the infrared IR transmitting and receiving elements are arranged on the entire outer surface (X axis, Y axis) of the touch screen, And recognizes the touch area.

This IR type touch screen has excellent performance in fast response speed and multi-touch function, and can be implemented at a relatively low cost, and is becoming a popular model of the future market activation and next generation touch screen.

FIG. 1 is a vertical sectional view of an infrared touch screen filter applied to an infrared touch screen. Referring to FIG. 1, a conventional infrared touch screen filter is manufactured. First, an infrared filter, After asking on four sides using a tape, the glass or transparent plate 30 is attached to the lower frame 40 of the infrared filter with a double-sided tape. Thereafter, a controller PCB for an infrared touch screen connected to the infrared light emitting element 10 and the infrared light receiving element 20 is mounted, and then the upper case 50 is fastened with screws using a guide 60. At this time, the guide 60 is bonded to the edge of the transparent or transparent plate 30 through the adhesive member.

As described above, in the conventional infrared touch screen filter manufacturing process, when the glass or transparent plate is attached, it may be attached with the sense of the assembler, or the controller PCB may not be attached due to the design dimension. Work rate frequently occurred.

In addition, when a glass or transparent plate, which is often mounted upright when it is applied to an actual product, is fixed only by a double-sided tape, the transparent plate is sagged due to its weight. There is a problem that an additional frame processing process is performed in which additional cost is incurred to prevent such sagging phenomenon.

The solution of the above-mentioned problems does not list all features of the present invention. Various means for solving the problems of the present invention can be understood in detail with reference to specific embodiments of the following detailed description.

In the infrared touch screen filter according to an embodiment of the present invention, a transparent plate may be fixedly disposed at a specific position of a lower frame through a guide for supporting an upper frame and a transparent plate therein, It is possible to suppress the transparent plate pressing phenomenon due to the impact or the subsequent process.

Further, during the manufacturing process of the touch screen filter, the adhesive or the waterproof sealant used in the process of attaching the transparent plate and the lower frame can be easily performed.

1 is a vertical sectional view of a conventional infrared touch screen filter.
2 is a vertical cross-sectional view of an infrared touch screen filter according to an embodiment of the present invention.
Figure 3 is a perspective view of the guide of Figure 2;
4 is an enlarged view of the guide shown in Fig.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. In the drawings, the same reference numerals are used throughout the specification to refer to the same or like parts.

Throughout the specification, when a part is referred to as being "connected" to another part, it includes not only "directly connected" but also "electrically connected" with another part in between . Also, when an element is referred to as "including" an element, it is to be understood that the element may include other elements as well as other elements, And does not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof.

Before describing the infrared touch screen filter of the present invention, the touch screen will be briefly described.

A touch screen is a device capable of inputting an input signal through the transmission of position coordinates on a touched screen when a specific position on the screen is directly or indirectly touched.

Such a touch screen is variously divided into an infrared sensor type, a capacitive type, and a resistive film type according to the recognition method of the touched position on the screen.

In particular, in the case of an infrared (IR) sensor system, a touch is sensed by using an infrared light emitting element and a light receiving element, and an input signal can be input through position coordinate transmission on the screen.

Hereinafter, an infrared touch screen filter according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a vertical sectional view of an infrared touch screen filter according to an embodiment of the present invention, FIG. 3 is a perspective view of the guide of FIG. 2, and FIG. 4 is an enlarged view of the guide shown in FIG.

Referring to FIG. 2, an infrared touch screen filter 100 according to an embodiment of the present invention includes an upper frame 110 having a hollow portion, a lower frame 120 having a hollow portion coupled to the upper frame 120, A guide 140 for fixing the transparent plate 130 to a specific position of the lower frame 120 by binding the upper frame 110 and the transparent plate 130, ).

The guide 140 is bonded to the edges and side surfaces of the transparent plate 130 through a binding member (for example, an adhesive).

Referring to FIGS. 3 and 4, the guide 140 may include a body 141, a first support 142, and a second support 143.

The body 141 may have a shape of a tetrahedron with one side of a vertical section having an inclined surface and the first support section 142 may have a vertical section such that the body section 141 is inserted into the binding groove (not shown) 141 projecting upwardly.

Here, the length? Of the first support portion 142 may be the same as the depth of the coupling groove (not shown) of the upper frame 110.

The second support portion 143 has a vertical cross section perpendicularly protruded downward at one end of the lower end of the body 141 and is formed to be in contact with a side surface of the transparent plate 130.

Here, the length (?) Of the second support portion 143 may be equal to or less than the side height of the transparent plate 130.

The lower surface of the body 141 is formed with a plurality of adhesive receiving grooves 144 at predetermined intervals so as to prevent the adhesive from being exposed to the outside when the transparent plate 130 is adhered. The shape of the adhesive receiving groove 144 is not specified.

Meanwhile, the guide 140 may be generally manufactured by an injection molding method. For example, a mold simulating the outer shape of a guide is prepared, and at least a pair of upper and lower cores is filled with a plastic-based raw material to manufacture a guide according to the mold.

Therefore, since the transparent plate 130 is fixedly disposed at a specific position of the lower frame 120 through the guide 140 when installed in the lower frame 120, The jumping phenomenon can be suppressed.

Further, during the manufacturing process of the touch screen filter, the adhesive or the waterproof sealant used in the process of attaching the transparent plate and the lower frame can be easily performed.

The embodiment of the present invention described above is not implemented only by the apparatus and the method, but may be implemented by a program realizing a function corresponding to the configuration of the embodiment of the present invention or a recording medium on which the program is recorded. The embodiments can be easily implemented by those skilled in the art from the description of the embodiments described above.
