The pixel arrangement direction of the linear infrared sensor 13 is defined as the X-axis, the direction perpendicular to the pixel arrangement-direction defines the axis, and the intersection of the X-axis and the γ-axis is the center 中间 of the intermediate pixel of the linear infrared detector 13. , ~'. When the fixed-size object 17 is located at the defect of the x-axis, the image A' imaged on the linear infrared sensor 13 is located at the defect; the object 17 moves from the point A to the point B in the direction of the parallel X-axis. The image B imaged in the linear infrared sensor 13 is offset from the defect by a distance, but the size of the image B' is the same as the size of the image A' (because the distance between the point a and the point b is linear infrared sensor) The distance of 13 is equal); when the object 17 moves closer to the linear infrared sensor 13 in the direction of the parallel γ axis to the point C, the image C' imaged on the linear infrared sensing cries will also deviate from the 0 point by a distance, Since the point c is relative to the point of the person plus g near the linear infrared sensation, the area of the pixel occupied by the image C' is larger than the area of the image occupant, and the area of the pixel is far away from the linear direction of the object 17; When the infrared sensor 13 moves to the D point, the image 成像 imaged on the linear infrared ray sensor 13 will also deviate from the 〇 point by a distance, since the point D is away from the linear infrared ray sensor 13 with respect to the point A, Therefore, the area occupied by the image D' is smaller than the image A, and the occupied pixel Product. In short, when the object 17 moves left and right relative to the linear infrared sensor 13, the image position of the image on the linear infrared sensor 13 will be different but the image size is the same, that is, the position of the object 17 The coordinates are related to the distance from the defect; when the object 前后 moves back and forth relative to the linear infrared sensor 13, the image size (ie, the number of pixels occupied) imaged on the linear infrared sensor 13 will be Different but the image positions are the same, that is, the coordinates of the position of the object 17 are related to the image size, and the image closer to the linear infrared sensor 13 is larger, and the far image is smaller. In this embodiment, the touch system 10 pre-determines the size of the coordinates of the point A and the image A as reference materials and stores them in the reduced position, as long as the object ιγ is imaged on the linear infrared sensor 13, according to the The reference and the image signal of the linear infrared sensor 13 can be used to derive the coordinates of the position of the object 17. 6 201039215 Assume that the center line of the broad side of the display panel 11 coincides with the Y axis, and the coordinates of the eight points are A, Κ, . The image Α 'size is &, then the coordinates of the position of the object 可由 can be obtained by the following expression: = Χ ί + like U + , where ", ύ is a constant 'X is the position where the object 17 is imaged on the linear infrared sensor 13, and s is the size of the image of the object 17 in the linear infrared sensor 13. As shown in FIG. 3 and FIG. 4, the infrared light L emitted from the infrared light source 12 is covered on the display panel u. When the fixed-size stylus 17 is touched on the display panel η, the infrared ray is reflected/reflected by the leather stylus ❹17. The light L, after passing through the lens 14, is imaged on the linear infrared sensor 13. The signal processor 15 receives the image signal of the linear infrared sensor 13, and performs the above operation according to the parameters of the image (for example, the size and position of the image) to calculate the position of the pressing point (ie, the touch of the stylus 17) The position is then output to the controller 16' and finally the sugar control 16_ should react and complete the corresponding press command. Since the touch system 10 includes only one linear infrared sensor 13, the size of the touch, 17 should be fixed. Of course, the touch system can (4) first store the size and size of the stylus, and the relationship between the size of the image formed in the online sensor when the size of the control pen is at the predetermined position of the sensor, so as to These data are used to calculate the actual coordinates of the size of the control pen application in this type of tumbling system. The infrared light emitted by the infrared light source 12 covers the surface of the display panel u, and the user touches the _ control button _ a point with the stylus 17 , and the pen tilts the infrared ray passing through the position and reflects it. The stylus 17 is imaged in the linear infrared ray. On the sensor 13, 'the position of the touch point can be calculated according to the position and size of the image on the linear infrared sensor ^, so that the structure of the closed material is fresh; (4) the infrared light is not affected by current, voltage and static electricity. Therefore, it is suitable for harsh environmental conditions. The touch system 2 of the second embodiment of the present invention is not shown in FIG. The display panel 21, the di-infrared source 22a, the second infrared source, the first linear infrared sensing 201039215 23a, the second linear infrared sensor 23b, the first lens 24a, the second lens 24b, and the signal processor 25 and controller 26. The display panel 21 has a rectangular shape, and the first infrared light source 22a, the first linear infrared sensor 23a and the first lens 24a and the second infrared light source 22b, the second linear infrared sensor 23b and the second lens 24b are located. The display panel 21 is opposite to both sides. The reflected light L1′ reflected by the touch unit 27 (for example, a finger or a stylus pen) emitted by the first infrared light source 22a passes through the first lens 24a and is imaged on the first linear infrared sensor 23a; the second infrared The reflected light L2 reflected by the light source 22b and reflected by the touch unit 27 passes through the second lens 24b and is imaged on the second linear infrared sensitizer 23A. The signal processor 15 can obtain the touch position of the touch unit 27 by processing the images of the first linear infrared sensor 23a and the second infrared sensor 23b, and the corresponding touch is performed by the controller 26 Control the reaction and complete the corresponding press command. Since the touch system 20 includes two sets of infrared light sources and sensors, a coordinate can be obtained by the linear infrared sensors 23a/23b, and the two coordinates can be calculated to obtain coordinates of the touch position. Therefore, the touch unit is The size of 27 does not need to be fixed (for example, the touch system can be touched with a finger). As shown in FIG. 6 , the touch control system 3 of the third embodiment of the present invention is substantially the same as the touch control system 20 of the second embodiment, and also includes a display panel 3 , a first infrared light source 3 , and a second The light source 32b, the first linear infrared sensor 33a, the second linear infrared sensor 33b, the first lens 34a, the second lens 34b, the signal processor 35, and the controller 36 are different in that: the first infrared The light source 32a, the first linear infrared sensor 33a and the first, the mirror 34a and the third infrared light source 32b, the second linear infrared sensing g 33b, and the second lens 34b are located on adjacent sides of the display panel 31. The coordinates of the touch position of the touch unit 37 can be obtained by the calculation method of the second embodiment. In summary, the present invention has indeed met the requirements of the invention patent, and the patent application is filed according to law. However, the above description is only a preferred embodiment of the present invention, and the scope of the patent application of the present invention cannot be limited thereby.
