New Description: [New Technology Field] [0001] The present invention relates to a touch module, and more particularly to an optical touch module applied to a display. [Prior Art] [0002] In recent years, since the manufacturing cost of a flat panel display has been remarkably lowered, a flat panel display has gradually become the mainstream of home televisions and computer screens. In addition, because flat-panel displays are lighter and thinner than TVs that traditionally use cathode ray tubes (CRTs), more and more can be found in public places such as train stations, hospitals, convenience stores, or movie theaters. Flat panel display, which can be used not only for the display of messages, but also for advertising purposes, and its commercial application can be said to be more and more extensive. [0003] As people's functional requirements for electronic devices or flat-panel displays become more diverse, their related technology research and development and manufacturing technologies are also changing with each passing day. 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 conventional resistive and capacitive types with optical ones. The optical touch module requires many components, which is not easy to achieve the requirements of thinning. Moreover, it is necessary to overcome the multi-touch by the commonly used "triangulation method".

As shown in FIG. 5B and FIG. 5C , the optical touch module 2 实施 of the embodiment of FIG. 2 a is mounted on the upper left corner of the display 8 , and the optical touch module 1 of the embodiment of FIG. 1 is mounted on the lower right corner of the display 8 . The two optical sensors 12 can be disposed at a corner of the inner portion of the front frame 81 for instantly capturing an opaque object around the light projection surface. In general, the target of the touch is usually achieved by the human fingers HI, H2, and H3. Therefore, as shown in FIG. 5B and FIG. 5C, the opaque object of the embodiment is the human finger HI, H2. H3 'The positions pressed by the fingers HI, H2, and H3 are touch points PI, P2, and P3, respectively. The purpose of this creation is to detect the position of the human finger Hi, H2, H3 by means of optical sensing, and then obtain the displacement change and velocity change of the touch points P1, P 2, P 3 and use Controls the software or hardware that operates an electronic device, such as a computer. Therefore, the principle of sensing is: using the optical sensor 12 to immediately capture the light projection surface; since the human fingers Η 1, H2, and H3 are opaque, an occlusion effect of light blocking can be generated. The optical sensor 丨2 detects the instantaneous coordinates of the touch points PI, Ρ2, Ρ3, and further obtains the moving speed and acceleration of the touch points pi, Ρ2, Ρ3 by a simple calculus operation. Further, since the light rays 92 emitted from the plurality of light guiding strips 11 are perpendicular to each other, any of the positions on the display 8 can be detected regardless of whether the fingers HI, Η2, Η3 are moved. [0013] In general, more touch points are generally more likely to cause inaccurate detection and misjudgment of coordinates. As shown in FIG. 5A and FIG. 5C, since the touch point Ρ1 of the finger hi has the same abscissa as the touch point Ρ2 of the finger Η2, if only the optical sensor 丨2 on the upper side is inevitable, There is a misjudgment of the form number Α0101 page 9 / a total of 22 pages M406218, or the touch points P1, P2 can not be clearly distinguished. Therefore, in this embodiment, the second or even the third light guiding strip 11 compensates for the error, eliminates the chance of misjudgment or unrecognizable, improves the accuracy, and makes the coordinates of the interpretation more precise. In other words, a plurality of optical touch modules can be installed in a display 8, so that the plurality of light guide bars 11 emit invisible light, and at the same time, the plurality of optical sensors 12 detect multiple touch points, thereby overcoming many Point touch "overlap point overlap" or "detect dead angle" problem, so it has higher precision and lower chance of misjudgment, which is very convenient. In addition, the detection principle of this creation does not use the traditional homing mother and method, so there is no need to use high-speed computing micro-control iron to save costs [0014] Of course, in other meal examples, the can be made into No, can be stem, the teacher 23⁄4 select the round 1 ~ solid 4 to find the: Ά Ά to match and combine with each other, so that the optical group of this creation is more flexible in application. / ' [0015] In this way, the shortcomings of the optical touch thinning of the present invention can overcome the problem of multiple touch points or "detecting dead angles", and lower the score; The present invention has a large commercial interest.
