New Description: [New Technology Field] This creation is related to a kind of micro-optical touch panel, especially a micro-optical touch panel which has the advantages of reducing the dead angle of touch, reducing the influence of external light source and simple device. . The prior art optical touch device is as shown in the ninth figure. The display panel 72 of a display 71 is provided with a touch panel 73 for displaying at least one touch shirt image 721. A plurality of corresponding cultivating 74 and reducing members 75 are respectively disposed on the four edges of the display panel 72, and the sensing light 74A' emitted by each of the illuminating members 74 is received by the corresponding receiving member 75, so that The plurality of sensing light 74A intersects the display panel 72 with a plurality of touch sensing points % corresponding to the at least one side control image 72i. When the touch sensing point is touched, the block is blocked. The parent touches the two sensing lights 74 of the touch sensing point 76 to activate the corresponding touch image 721. The traditional device has the following problems: [1] The touch has a dead angle. Referring to the ninth figure, the touch sensing point 76 of the conventional device is formed by the intersection of the sensed light 74, and the number of the light emitting member and the receiving member is limited by the area (for example, a small-area mobile phone screen). Restricted, and the arbitrary two illuminating members % must have the same design distance between any two receiving members 7s) (the mounting distance is the touch dead angle A), if the touch The control image 721 is located on the touch dead angle a, and the root core method enters the touch operation of 3 M426081. Of course, the touch dead angle A can be flashed off, but the number of touch images 721 that can be displayed is relatively limited. [2] The influence of Yi Wen's external glare. If the sensed light and the external light emitted by the filaments of the filament are both visible light, once the outside light is too strong, it will interfere with the intensity of the light received by the receiving member, thereby causing misjudgment. [3] It is susceptible to interference from adjacent internal sources. If both sides of the traditional device

In particular, the problems of the scales include: the touch has a dead angle, the shadow of the external glare 9 and the interference of the adjacent light source of the _ part. The technical means for solving the above problems is to provide a micro-optical touch panel system for mounting on a display having a front edge portion, a pair of the first pair, and the pair of chambers. The display portion is between the air-like edge portions and is configured to display at least one touch signal, and the pair of first and second cargo terminals 4 are opposite to each other, and the pair of linear emission portions 4 are opposite to each other. A light guiding portion 10C is a light transmitting structure, and has a light guiding channel 101 and a light guiding portion 102. The original light 100 emitted by the semiconductor laser 10B is ', and is incident into the light guiding channel 1〇. After 1 , it is guided by the light guiding portion 1〇2 to become a 6-sea surface sensing light signal 11 (the two original lights of different colors become the first sense as shown in the fourth figure) The blue surface sensing optical signal of the measuring wavelength λ1 is irradiated with the red surface sensing optical signal having the second sensing wavelength, and the light guiding portion 102 is substantially saw-toothed, and along the light guiding channel 1〇1 The direction 'is distributed outside the light guiding portion 10C. The optical component 22 can be a filter. If the surface sensing optical signal u is red (that is, the sensing wavelength is the wavelength of red light), the corresponding optical component 22 is used to pass the wavelength of the light (filtering the external impurity). Light), and it is confirmed that the corresponding linear charge coupling device 21 is also a red square sensing light signal 11. The focusing element 23 can be a focusing lens group which is formed by a plurality of focusing lenses arranged in a line. The display 90 further includes a touch panel 95 (see FIG. 5), which is disposed on the display portion 93 and located in the pair of first and second edge portions 91 and 92. The touch panel 95 is for pressing. (ie, blocking) and clicking the touch signal 94. The display 90 can be a personal digital assistant (see the first embodiment shown in the first figure), a screen, a panel (see the second embodiment shown in Figure 7), and an associated image display device. The actual use of the present invention is as follows: Referring to the fourth and fifth figures, the pair of linear transmitting portions 10, the pair of linear receiving portions 20, and the control device 30 are activated, the pair of linear transmitting portions 1 respectively facing the pair The linear contact (four) 卩 20 emits the _ ❹ ❹ u, the surface sensing optical signal 11 intersects on the display portion 93 to form the virtual touch area 1 〇 A, and the plurality of virtual touch points 12 on the corresponding The at least one touch signal 94 displayed on the display unit 93 (for example, the first touch signal 941, the second touch signal 942, and the second touch signal 943) is assumed to be pressed (see the sixth figure). When the first touch signal 941 is clicked, the virtual touch point 12 ′ corresponding to the first touch signal 941 is blocked from being received by the two linear charge coupled devices 21 (or the amount of light is reduced). The surface of the virtual touch point 12 senses the optical signal 11 , and the detecting unit 31 detects the coordinate point of the virtual touch point 12 by two linear charge coupled devices 21 (assumed to be (not)). Further determining that the first touch signal 941 is selected and activated, when the first touch signal 9 is released 41. The detecting component 31 closes the first touch signal 942. Referring to the seventh figure, when the fourth touch signal 944 is pressed and touched, it is assumed that the virtual touch point 12 corresponding thereto is not only blocked, and the corresponding surface sensing optical signal 11 is taken from the virtual touch. The point 12 is reflected to the other non-corresponding linear charge coupling device 21, because the sensing wavelength 0 of the surface sensing optical signal u is set as the first sensing wavelength; U), the linear corresponding to the non-correspondence The optical element 22 in front of the charge coupled device 21 has a different wavelength (assuming the second sensing wavelength is 2), and therefore is blocked by the optical element 22 (of course, the external stray light is also filtered by the same wavelength of light. Blocked), will not cause the non-corresponding linear electric M426081 charge coupling device 21 to receive and misjudge. The advantages and functions of this creation can be summarized as follows: [1] Reduce the dead angle of the touch. In this creation, two kinds of miscellaneous emission parts emit two kinds of surface-sensing optical signals 'almost completely covering the display part (including the touch signals displayed by them)' and intersecting them to form a virtual touch area, and two linearities are set. The charge-coupled device subtracts two surface-sensing optical signals respectively, and any touch signal on the touch display unit can smoothly start the touch signal, which can reduce the position of the touch signal just before the transmitter is located at the transmitter. With the edge of the receiver dead angle (the number of single-point transmitters and receivers has a certain limit) 'there must be left and right to move the press to start the touch signal. Therefore, the touch dead angle can be reduced. [2] Reduce the impact of external light sources. The present invention controls the semiconductor laser pulse modulation to emit the original light having the sensing wavelength (becomes the surface sensing signal after being processed by the light guiding portion), and the optical element for filtering the wavelength of the wavelength is arranged before the linear charge coupled device. The stray light from different wavelengths of light from the outside, and only receiving the surface sensing signal with the corresponding sensing wavelength, can greatly reduce the external charge (or light from different sensing wavelengths on the adjacent side) to the linear charge The impact of the device. [3] The device is simple. In the present invention, the light guiding unit is configured to convert the original light (point source) emitted by the semiconductor laser into a surface sensing light signal (surface light source), and then a linear charge coupled device (known device) is used to receive the surface light source, so that the device is relatively simple. The above is only a detailed description of the preferred embodiments of the present invention. Any modifications and variations of the present invention will be made without departing from the spirit and scope of the present invention. From the above detailed description, it will be apparent to those skilled in the art that the present invention can indeed achieve the aforementioned objectives, which have been in compliance with the provisions of the Patent Law and have filed a patent application.
