For example, the touch screen needs to make it easy for people to operate computers, mobile phones, stereos, refrigerators or other electronic devices. With its screen display and screen press control, people can abandon complex keyboards and buttons. Operation, through the clearly marked pattern on the screen and the user-friendly interface to achieve the purpose of display and touch operation. [0004] At present, large-size touch screens (generally larger than 10.1 inches) are gradually replacing the traditional resistive or capacitive touch with optical touch. The optical touch module requires many components and is not easy to achieve the requirements of thinning; and if you want to overcome the multi-form number A0101 by the commonly used "triangulation method", page 3 of 19 M408077 Controlled "contact point overlap" or "detecting dead angle" problems require multiple optical sensors (which can be cameras, cameras) and higher-level microcontrollers or computing chips to accurately calculate Touch points, to avoid misjudging the touch points that people press; therefore, the cost required is higher.

Or "detect dead angle" problem, and at a lower cost to achieve accurate calculation of touch points, to avoid misjudging people to press the touch point. [0015] In order to familiarize the person skilled in the art with the purpose, features and functions of the present invention, the present invention will be described in detail by the following specific embodiments and with the accompanying drawings. [Embodiment] [0016] Please refer to FIG. 1 and FIG. 2 at the same time. FIG. 1 is a schematic diagram of the optical touch module of the present invention, and FIG. 2 is a perspective view of the optical touch module. As shown in FIG. 1 and FIG. 2, an optical touch module 11 includes a lamp cover form number A0101, page 5/19 pages of M408077 112, a lamp cover 112', a light guide bar 113, and a light guide bar. ! 13, a plurality of light sources 11 4, two optical sensors 111 and a transparent plate 丨 2. The two light guiding strips 113 and 113' are both long-axis type structures, and the two lampshades 112 and 112 are respectively wrapped on the sides of the two light guiding strips 113 and 113. Each of the optical sensors n1 is disposed at an axial end of any of the light guiding strips 113, 113'. Therefore, the optical sensor 111 on the left side is adjacent to the two light guiding strips 113, 113' at the same time, and is also adjacent to the two lampshades 112, 12, respectively. In addition, each of the light sources 114 is located at one of the axial ends of the light guiding strips 113, 113 adjacent to the light guiding strips 113, 113. Thus, the light source 114 can directly emit light to the light source 114. The light guide strips 113, 113' are internal; that is, there is no blockage between the light source 114 and the light guide strips Π3, 4i3, and there is no blocking structure. Or the shielding material, and the light source 114 is disposed close to the light guiding strips jig, 113, so that the light emitted by the light source 114 does not have light loss 'can directly enter the light guiding strip 113, 113' In the preferred embodiment, the light source Η 4 may be a Light Emitting Diode (LED), and the light emitting diode system emits an infrared (Inf rared) frequency band. Invisible light. In addition, between the optical sensor 111 and the lamp cover 112 (or the lamp cover 112), it can also be coupled and fixed through a fixing frame 14; when the optical sensor U1 and the lamp cover 112 (or the lamp cover 112' The light source 114 is located in the fixed frame 14 and is covered by the fixed truss 14 through the fixed frame η, and thus the light energy leakage of the light source 114 can be further prevented. The transparent plate 12 is parallel to the two light guiding strips 113, 113 and is disposed adjacent to the optical sensor 111. The light guiding strip 113 includes a light exiting surface 113A'. The light guiding strip 113' includes a light emitting surface H3A'. The lampshade form number A0101, page 6 of 19, is closely wrapped around the light guide bar 113, and is different from the three sides of the light-emitting surface 113A. The lamp cover 112' is tightly wrapped around the light guide bar 113. Different from the three sides of the light-emitting surface 113A', and the surface adjacent to the light-shielding strips 113, 113' of the lampshade 112, 112' may be a coated reflective paint layer, a white surface layer or an electric meter. Metal layer. Thus, the light rays emitted from the three sides of the light guiding strips 113, 113' can be reflected by the globes 112, 112' and re-entered into the light guiding strips 113, 113' to prevent loss of light energy. In addition, after the plurality of light sources 114 emit light of invisible light, the light is transmitted and advanced in the axial direction inside the light guiding strip 113' 113', gradually away from the light source 114, and then emitted from the light emitting surface 113A '113A'. And the emitted light is parallel to the transparent plate 12. Again, the experiment by the creator of the case has been repeated for a long time. The ratio of the length (L) and width (W) of the illuminating surface is between 79.95:1~53. 3:1, the light loss is low. The effect of optical touch is more sensitive. [0017] In addition, as shown in FIG. 2, the left lamp cover 112 further includes a reflective plate body 112A disposed at another axial end of the light guiding strip 113 not adjacent to the light source 114. Therefore, the left side of the light guiding strip 11 3 is directly adjacent to the light source 114 on the right side of the reflecting plate body 112A′. In a preferred embodiment, the light guiding strip 113 is in close contact with the reflecting plate body 112A, and the reflecting plate body 112A may include a coated reflective coating layer and a white surface on the surface in contact with the light guiding strip 113. The surface layer or the plated metal layer, when the light exits the axial end of the light guiding strip 113 and touches the reflecting plate body ii2A, it can be totally reflected by the reflecting plate body 112A, and enters the light guiding strip 113 again. Internal 'reduces light energy loss. Further, based on the manufacturing convenience, the reflecting plate body 112A and the lamp cover 112 are preferably integrally formed. Form No. A0101 Page 7 of 19 M408077. Further, as shown in Figs. 1 and 2, the axial length of the light guiding strip 113' is larger than the axial length of the light guiding strip 113. In general, if the axial length of a light guiding strip is too long (that is, the length (L) is large), the luminous flux at the end portion is small and the brightness is insufficient; therefore, the light guiding strip 113 of the present embodiment is The light source 丨丨 4 is respectively disposed at the left and right ends of the light guiding strip 11 3 ′, and the two light sources 114 are respectively adjacent to the two axial ends of the light guiding strip 113 ′, so the two lamps The source 114 can directly emit light to the inside of the light guiding strip 113, preventing the excessively long axial length and causing the disadvantage of insufficient brightness. Further, as shown by the light guiding strip 113, since the axial length is short (that is, the length is small), the light flux at the end of the light guiding strip 113 is sufficient, and only the reflecting plate body 112 is required to reflect light to prevent light leakage. can. Therefore, the lamp cover of the optical touch module n is configured by using the reflector body 112A (ie, the lamp cover 112), or the structure in which the lamp source 114 is disposed at both axial ends (ie, the lamp cover 112), which should be regarded as The length of the light guide bar depends. [0018] Thereby, the optical touch module u of the present invention guides the light through the light guide strip 113, and the light cover 112, 112, to reflect the light, so that the plurality of light rays are respectively perpendicular to the two light exiting surfaces. 113A, n3A, and shot, so multiple shots of light can form a light projection surface (not labeled) 〇 [0019] 凊 See also 圊 3, Figure 3 shows the creative optical touch module used Schematic diagram of the structure of the display. A display structure 1 can be constructed by mounting the optical touch module 11 on a liquid crystal panel 15 and a backlight module 16. The backlight module 16 can be a "direct-lit backlight module" or a "side-lit backlight module". In the figure, the backlight module 16 includes a light guide plate 163 and a diffusion film 162'. The brightness enhancement film 161 and the multi-form number A0101 page 8/a total of 9 pages of visible light source 164, and the visible light source 丨 64 are located on the left side of the backlight module 16, thus being a "sidelight type backlight module" group". The backlight module 16 is configured to provide a backlight of the liquid crystal panel 15 so that the video image presented on the liquid crystal panel 15 can be seen. Then, the transparent board 12 and the optical touch module 11 are placed above the liquid crystal panel 15. The display structure 1 can have a touch function, and the transparent board 12 aims to prevent people from contacting. The liquid crystal panel 15 is pressed too hard and is weak. The material of the transparent plate 12 is generally made of glass, acrylic, plastic knee resin or other transparent polymer. [0020] Please refer to FIG. 4 and FIG. 5 at the same time. FIG. 4 is a schematic diagram of the light concealing principle of the optical touch module of the present invention, and FIG. 5 illustrates the light shielding principle of the optical touch module of the present invention. As shown in FIG. 4 and FIG. 5, an optical touch module 11 is placed above the display structure ,, and another optical touch module u is placed under the display structure 1 and the optical touch mode is above. The group includes a horizontally disposed light guiding strip 113, a vertically disposed light guiding strip 113 and two optical sensors 111; the lower optical touch module includes a horizontally disposed light guiding strip 113 and an optical The sensor 丨丨丨; therefore, a plurality of optical sensors 111 are disposed at each corner of the display structure ,, and can be used to instantly capture an opaque object around the light projection surface. Generally, the target of the touch is usually achieved by the human finger H1. Therefore, as shown in FIG. 4 and FIG. 5, the opaque object of the embodiment is a human finger, and the finger H1 is pressed. The position is the touch point ρι. The purpose of this creation is to detect the position of the human finger H1 by means of optical sensing, thereby obtaining the displacement change and speed change of the touch point P1, and for controlling and operating the form number A0101. Page 19 M408077 is the software or hardware of the electronic device; therefore, the principle of its sensing is: a using the optical sensor to instantly capture the light projection surface around the display structure 1, b. the human finger H1 is impenetrable The occlusion effect of light-induced light blocking, and c. the multiple light-emitting directions are perpendicular to each other; therefore, the plurality of optical sensors 111 can detect the corresponding ordinate of the touch point P Cross-coordinate. Therefore, whether the finger Η 1 is moved to any position around the transparent plate 12 can be detected. In the preferred embodiment, the optical sensor 111 can be a camera, a camera, a complementary metal oxide semiconductor ( Complementary Metal Oxide Semicon_ ductor, CMOS) or charge coupled component (Charge coupled
