I. The edge system uses a thin optical component or a surface acoustic wave touch panel to have a good light transmission. At the same time, it does not require the installation of sophisticated touch signals, so the structure is simple. The present invention is further described in detail with reference to the accompanying drawings, and is not limited by the current, voltage, and static. Referring to FIG. 1 and FIG. 2, the touch system of the first embodiment of the present invention does not have a panel: a straight mirror 12, an infrared light source 13, an infrared image sensor 14, and a right angle 稜鏡I2 including a first surface. m, second surface m and third surface (2). The second surface 122 is perpendicular to the third surface 123, and the angle between the first surface 121 and the second surface 122 and the second surface 123 is 45 degrees. The red light source 13 and the infrared image sensor 14 are disposed adjacent to the first surface 121. The illumination light source 15 is adjacent to the second surface 122' to display the surface of the surface of the third surface 123. The display panel u has an opposite outer surface U1 and an inner surface, and the inner surface is closer to the third surface of the third surface of the third surface 123 than the display surface 11 is deformed to generate _, so that the deformed age panel u can be the third 5 201040811 * Surface 123 contact. The infrared light L2 emitted from the infrared light element 13 can be incident on all regions ' of the third surface 123' and the incident angle of the infrared light L2 at the third surface 123 is greater than or equal to the critical angle at which total reflection occurs. The infrared light L2 emitted from the infrared light source 13 enters the right angle edge through the first surface 121, and the inside of the second surface 123 is totally reflected by the second surface 123 and then incident on the second surface 122 and then emitted by the first surface 121, and all the outgoing light L2' are in Imaging is performed on the infrared image sensor 14. Since the second surface 122 is perpendicular to the third surface 123', therefore, the totally reflected infrared light L2 at the third surface 123 is also totally reflected at the second surface 122, and the outgoing light L2' is parallel to the incident light L2. After the infrared light L2 incident on different regions of the third surface 123 is totally reflected, the emitted light L2' will be emitted from different regions of the first surface 121 and then imaged in different regions of the infrared sensor 14, that is, the infrared sensor The different areas on the 14 can correspond to different pixels on the display panel ^. The 'infrared light source 13 is a light emitting diode or a laser diode, and the infrared image sensing device 14 is a charge coupled device (CCD) sensor or a complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor ' CMOS) sensor. The light LI emitted by the illumination source 15 enters the right angle 稜鏡12 经由 via the second surface 122, and then exits from the third surface 123 to illuminate the display panel 11 to perform the function of displaying the fascia. Of course, if the touch system 10 does not need to display the facet, the illumination source 15 can be omitted. The signal processor 16 is electrically connected to the infrared image sensor 14 and the controller π, respectively, and the signal processor 16 receives the infrared image sensor. The image signal of w is processed and processed, and the processing result is output to the controller 17. As shown in FIG. 3, 'the finger or the stylus touches the outer surface 1U of the display panel ^ to deform the display panel 11' because the distance between the inner surface 1; 12 and the third surface 123 is smaller than the shape variable, so that the display panel is inside the display panel The surface 112 is in contact with the third surface 123 of the right angle 稜鏡12, which in turn causes a slight deformation of the third surface 123; at this time, the incident light L2 entering the right angle 稜鏡 22 from the first surface 121 from 6 201040811 reaches the contact surface In the light, the incident angle changes such that the incident angle of some of the infrared light L2 at the third surface 123 is smaller than the critical angle, so that the magnitude of the reflected light signal at the contact surface is abrupt. The abrupt reflected light signal reaches the first surface 121 and produces an image signal on the image sensor 14 that is different from the degree of shading of the unpressed area. The image signal on the image sensor 14 is processed by the signal processor 16 to detect the position of the pressed point, that is, the pixel point, and finally the controller 17 reacts to the corresponding touch and completes the corresponding pressing instruction. Since the touch system 1 is configured by an optical element right angle 稜鏡12 and an infrared light source 13, the touch body has good performance compared with a common resistive touch panel, a capacitive touch panel or a surface acoustic wave touch panel. The light transmission is not afraid of external factors such as static electricity; at the same time, it is not necessary to install sophisticated touch circuits to calculate the coordinates of the touch points', thus the structure is simple and the cost is low; and, since the infrared rays are free from current, voltage and static electricity Interference, so it can be suitable for harsh environmental conditions. As shown in FIG. 4, the touch system 2 of the second embodiment of the present invention is applicable to a display device of a large screen, which includes a display panel 21 of a larger size, a signal processor 26, and a controller 27, and the number is five. Right angle 稜鏡 22, infrared light source 23, infrared image sensor 24 and illumination source 25. Since the size of the display panel 21 is larger than that of the display panel u, if a right angle 〇稜鏡22 is used for a large-sized touch display device, the required right angle 稜鏡 size is large, so that the thickness and volume of the touch system 20 are increased. Large, therefore, in order to reduce the thickness and volume, the present embodiment employs five right-angled turns 22 of relatively small size. Of course, the right angle, the number of mirrors 22 = is not limited to five, and an appropriate number I can be selected according to the size of the display panel 21, such as two, three or each pixel of the display panel 21 facing a right angle 稜鏡22. The straight corner 22 has a first surface 221 and a second surface 222 and a third surface 223 which are perpendicular to each other. The angle between the first surface 221 and the second surface 222 and the third surface 223 is 45 degrees. Wherein, the five right angles 22 are arranged in a straight line, and the five third surfaces 223 are located on the same plane, and the second surface is close to the first - 201040811 * surface 221 of the adjacent straight ribs. The infrared source 23 and the infrared image sensor 24 are disposed adjacent to the first surface 221, the illumination source 25 is adjacent to the second surface 222, and the display panel 21 is positioned above the third surface 223. When not pressed, the light emitted by the infrared light source 23 enters the right-angle prism 22 through the first surface 221, is totally reflected on the third surface 223 and the second surface 222, and finally exits from the first surface 221, and the emitted light is sensed in the infrared image. The image is formed on the device 24; when pressed, the light signal from the infrared light source 23 enters the right angle 稜鏡22 and the light signal to the pressing portion is abruptly changed, so that the infrared image sensor 24 is distinguished from the untouched area. The image signal on the infrared image sensor 24 is processed by the signal processing device 26 to detect the position of the pressing point, and finally the controller 27 reacts to the corresponding touch' and completes the corresponding pressing command. Of course, the number of right angles 稜鏡 22 is not limited to five, and may be arranged in a matrix corresponding to the number of pixels of the display panel 21; or, each row of pixels or pixels corresponds to a right angle 稜鏡22. = The above mentioned 'the present hair meets the requirements of the invention patent, and is submitted according to law = Shen.
