[Embodiment] Simultaneously, referring to FIG. 1, FIG. 1 is a schematic diagram showing the structure of the display of the present invention. As shown in FIG. 1, an optical touch module 1A includes a plurality of light guide bars 11, a plurality of light sources 13, a plurality of light covers 15, and a plurality of optical sensors 12. The light guiding strip 11 has a long axis structure, and the light guiding strip u includes a light incident surface 11A and a light emitting surface 11B. The light incident surface iiA is located at an axial end of the light guiding strip 11, and the light emitting surface 11B is located on the side of the light guiding strip. In the preferred embodiment, the light incident surface 11A is perpendicular to the light exiting surface. The light source 13 can be a Light Emitting Diode (LED) for emitting an invisible light in the infrared frequency band and the light source 13 is disposed on the light guiding surface of the light incident surface 11A. The end portion 11 is used to project the invisible light emitted to the inside of the light guiding strip. The light cover 15 covers the other three sides of the light guiding strip 11 different from the light emitting surface 11B. The purpose of the light cover 15 is to reflect the invisible light, so that the invisible light leaving the other three sides re-enters the light guiding light. The inside of the strip 1 1 can be used to guide a plurality of light rays from the light exit surface 11B of the light guide strip 11 through the light guide strip 11 and the cover 15 . In the preferred embodiment, the lamp cover 15 is clamped and fixed by the tight fit (interference fit). Thus, the light guide bar 11 and the lamp cover 15 can be tightly clamped. The optical sensor 12 is respectively located at the axial end of the two light guiding strips 11 and is fixedly connected to the lamp cover 15 through a fixing plate 14 and the optical sensor 12 is adjacent to the lamp. Source 13 is set. Therefore, the optical touch module 1 has a modular structure, which facilitates the installation and assembly of the optical touch module 1 by a factory operator. In addition, in the embodiment of the preferred form number A0101, the light source 13 is in close contact with the axial end of the light guiding strip 11, so that the light source 13 can be invisible. The light is directly projected into the interior of the light guiding strip 11 to reduce the loss of light energy that is dissipated and to improve the utilization of light energy. As shown in FIG. 1 'When a plurality of light rays exit the light guiding strip 11 from the light emitting surface 11B, a plurality of light rays can be defined as a light projection surface (not labeled), and the optical sensor 12 can be photographed instantaneously. A non-transparent body around the light projection surface. Generally, the optical sensor 12 can be a camera, a camera, a Complementary Metal Oxide Semiconductor (CMOS) or a Charge Coupled Device (CCD), so that the optical sensor can be transmitted through the optical sensor. To shoot and manipulate images. In addition, the optical touch module 1 further includes a transparent plate 16 at the lower side thereof, and the corner of the transparent plate 16 is cut by a truncated angle 1 61. Therefore, the truncated angle 1 '61奚ιί optical sensor 12 is adjacent to each other. And corresponding. When the optical touch module 1 including the transparent board 16 is assembled and combined with other electronic devices (in the present embodiment, the display structure), the wearing angle 161 of the transparent plate 16 can follow the optical sensing. The fixing plate 14 is adjacent to the contour of the lamp cover 15 and does not occupy extra space. [0018] The optical touch module 1A is mounted in a display structure, the display structure 1 includes a front frame 21, a rear case 22, a liquid crystal panel 23, and an optical module. 24, the optical touch module 1 〇, the liquid crystal panel 23 and the backlight module 24 are sequentially arranged from front to back; here, the top of the figure is. In front of the display structure 1, the lower side of the figure is the rear of the display structure 1. Then, the front frame 21 and the rear case 22 are respectively clamped back and forth, and the optical touch module 10, the liquid crystal panel 23, and the backlight module 24 are fixed in the display structure 1. The module 24, that is, the form number Α0101, page 7 / total 20 pages, M408047, can provide the liquid crystal panel 23 as a backlight, so that the image video or picture presented by the liquid crystal panel 23 can be seen from the front of the display structure 1. Moreover, the optical touch module 10 is located above the liquid crystal panel 23, so that the display structure 1 can have a touch control function, and the transparent plate 16 can be used to prevent people from being overpowered when touched. The fragile liquid crystal panel 23 is crushed and damaged. [0019] Next, the touch principle of the display structure 1 will be described. Please refer to FIG. 2 and FIG. 3 at the same time. FIG. 2 is a schematic diagram of optical sensing of the structure of the creation display, and FIG. 3 is a perspective view of the optical sensing of the structure of the creation display. As shown in FIG. 2 and FIG. 3 , the liquid crystal panel 23 of the display structure 1 has a rectangular shape (which may of course be designed as a square). The optical touch module 1 includes four light guiding strips 11 and a plurality of light sources 13 . Four light guides 15 and four optical sensors 12 are disposed on the four sides of the liquid crystal panel 23 respectively. The four optical sensors 12 are respectively disposed at four corners of the liquid crystal panel 23, and therefore, The axial directions of the four light guiding strips 11 are respectively attached to the four sides of the liquid crystal panel 23. Thus, the 'four optical sensor 12 can be used to instantly capture the non-transparent body around the light projection surface. In general, the target of touch is usually achieved by the human fingers HI, H2, and H3. Therefore, as shown in FIG. 2 and FIG. 3, the non-transparent body of the present embodiment is a human finger H1, H2 'H3. The positions pressed by the fingers HI, H2, and H3 are the purpose of the touch points P1, p2, and p3, respectively, and the positions of the human fingers HI, Η 2 ' Η 3 are detected by optical sensing. In turn, the displacement changes and speed changes of the touch points Ρ1, ρ2, and ρ3 are obtained, and used to control the software or hardware of the operating electronic device (for example, the display structure 1 of the present invention). Therefore, the principle of the sensing is: using the optical sensor 12 to immediately capture the light projection surface; because the form number A0101, page 8 of 20, the human fingers HI, H2, H3 are opaque, Therefore, the occlusion effect of the light blocking can be generated, so that the optical sensor 12 can detect the instantaneous coordinates of the touch points P1 and P2 ′ P3, and the touch point PI can be further obtained through a simple calculus operation. 'P2, P3 movement speed and acceleration. Further, since the light rays 92 emitted from the plurality of light guiding strips 11 are perpendicular to each other, any finger HI, H2, H3 can be detected regardless of any position on the display structure i. [0020] Generally speaking, more touch points are generally more likely to cause inaccurate detection and misjudgment of coordinates. As shown in FIG. 2 and FIG. 3, since the touch point P2 of the finger H2 and the touch point p3 of the finger H3 have the same abscissa, if only the single side optical sensor 12 is used, there will inevitably be The situation of misjudgment' may not distinguish the touch points P2 and P. Therefore, in this embodiment, the error is compensated by the sum of the four light guiding strips 11, the probability of misjudgment or unrecognizable is eliminated, the accuracy is improved, and the coordinates of the interpretation are more accurate. In other words, a plurality of light guiding strips 11 can be installed in a display structure 1 to make the plurality of light guiding strips u emit invisible light, and at the same time, the plurality of optical sensors 12_ multiple touch points can be overcome. Multi-touch, overlap of touch points or "detecting dead angles", so it has higher accuracy 'lower chance of false positives, very convenient. Therefore, the display structure 1 of the present invention solves the problem of the calculation delay of the traditional triangular operation because of the function of simultaneous detection of the triangle, and does not need to set a high-order processing and operation chip, thereby saving the hard of the high-order processor (processing the wafer). Body cost. [0021] Therefore, the function of the display structure 1 of the present invention is: a. multi-touch with the same time, b extremely fast reflecting time, and detecting two touch points at different times. Therefore, based on the above-mentioned effects, the display form number of the creation A0101 page 9 / 20 pages M408047 structure 1 can develop the following applications; please refer to FIG. 4, FIG. 4 shows the first application of the structure of the creation display Schematically, the display structure 1 can load a touch keyboard function, so that the liquid crystal panel 23 presents the appearance of a keyboard. When people quickly press the surface of the liquid crystal panel 23 with the ten fingers of both hands (the speed may be as high as 5 to 8 times per second), the four optical sensors 12 can be quickly detected and learned. The position of each finger pressing, through its fast reflection time to determine the letter or keyboard button corresponding to the individual finger, to achieve the purpose of "virtual touch keyboard". [0022] Please refer to FIG. 5. FIG. 5 is a schematic diagram of a second application of the structure of the creation display. As shown in Figure 5, when the computer needs to be warm booted, it can simultaneously press the three buttons "Ctrl", "Alt" and "Delete" of the ¥ on the LCD screen 23 with three fingers; The structure 1 detects a plurality of touch points through the four optical sensors 12, so that even if the two buttons "Ctrl" and "Alt" are at the same horizontal position, they can be compensated by the plurality of optical sensors 12. The hidden light, so the display structure 1 can detect multiple touch points at the same time, and there is no longer the disadvantage that the "touch point overlap" can not be detected. [0023] Referring to FIG. 6, FIG. 6 is a schematic diagram of a third application of the structure of the creation display. As shown in Fig. 6, the display structure 1 can also be loaded with a function of a video telephone or a network telephone, so that the liquid crystal panel 23 exhibits the appearance of a telephone. Thus, when the display structure 1 is connected to an earphone 81 and a microphone 82, one can press the liquid crystal panel 23 of the display structure 1 and detect the telephone number dialed by the four optical sensors 12. Then communicate through the earphone 81 and the microphone 82; very convenient form number A0101 page 10/total 20 pages [0024] Thereby, the display structure of the present invention can solve the multi-touch problem of the traditional optical touch. Overcoming the problem of “touch point overlap” or “detecting dead angles”, the display structure of this creation can be more diversified, and more application software can be developed, which has enormous commercial interests [0025] Although the present invention has been disclosed in the above embodiments, the specific embodiments disclosed herein are not intended to limit the present invention, and those skilled in the art can make various changes without departing from the spirit and scope of the present invention.
