近年來，觸控式面板(TouchPanel)的應用愈來愈廣泛，例 如個人數位助理褽置（Personal Digital Assistant )、遊客導覽系 統、自動櫃員機、銷售點終端機等。而目前觸控式面板依其使 用技術的不同，可區分為電阻式觸控面板、電容式觸控面板、 以及紅外線式觸控面板等種類。 以電容式觸控面板來說，主要的做法是在玻璃板上鍍上氧 化銻錫薄膜(ATOFilm)及銀漿線等導電材料，外側再覆上防刮 塗膜。玻璃板周圍的電極會在外側導電層上產生均勻的低壓電 場。内侧導電層則可以提供電磁屏蔽，並減低雜訊。每當手指 接觸到螢幕時，就會與外侧導電層上的f懸生電_合，而 吸去微小的電流，藉由各電極負責測量來自各個祕的電流大 士來定出手指的座標。電容式觸控面板的優點為穩定性高、透 光度佳S面硬度強，但缺點為價格較高且製程較為複雜。 πτοΐη摘f面板㈣’主要是透魏化_導電薄膜 1 m)及-片氧化錮錫導電玻璃（IT〇 Giass)而形成 玻璃與導電_之間，則—層聚g旨製成的微小分隔點隔開。 沿著玻璃的X軸，以及導電薄膜的¥轴，各有一個控 施加微小的電壓梯度。备备丰扣鎞 ° θ 板的優點為製造成本較低、構造較簡易，但透光度‘面; 201030580 均差於電.容_控面板。 ^ ^卜線式觸控面板則利用光源遮斷原理，在顯示器 ❿In recent years, touch panels have become more widely used, such as Personal Digital Assistants, visitor navigation systems, automated teller machines, point-of-sale terminals, and the like. Currently, the touch panel can be classified into a resistive touch panel, a capacitive touch panel, and an infrared touch panel depending on the technology used. In the case of a capacitive touch panel, the main method is to plate a conductive material such as a bismuth oxide film (ATOFilm) and a silver paste line on the glass plate, and the outer side is coated with a scratch-resistant coating film. The electrodes around the glass plate produce a uniform low voltage field across the outer conductive layer. The inner conductive layer provides electromagnetic shielding and reduces noise. Whenever the finger touches the screen, it will collide with the f on the outer conductive layer, and absorb a small current. The electrodes are responsible for measuring the coordinates of the finger from each of the current currents. The advantages of the capacitive touch panel are high stability and good transparency. The S surface is strong, but the disadvantage is that the price is high and the process is complicated. Πτοΐη extract f panel (four) 'mainly through the Weihua _ conductive film 1 m) and - sheet yttria conductive glass (IT 〇 Gias) to form a thin separation between glass and conductive _ Point separated. Along the X-axis of the glass, and the ¥ axis of the conductive film, each has a small applied voltage gradient. The advantage of the 丰 ° θ plate is that the manufacturing cost is lower and the structure is simpler, but the transmittance is 'face; 201030580 is worse than the electric capacity _ control panel. ^ ^Wire-type touch panel uses the light source to interrupt the principle, in the display ❿

For example, the "Location Detection Device" disclosed in 2〇_5123 uses the principle of infrared to detect a specific location. Please refer to the first f'. This figure is a conventional positional device - the appearance of the specific embodiment is not intended. As shown in the first figure, the position detecting device 1 includes a frame U, an infrared light source 13 133, 135, 137, and a light receiver 132: 13 hearts 136, 138. The infrared light sources 131, 133, i35, 137 and the light receivers 132, 134, 136, 138 are disposed on the frame 11, and the light receivers 32, 134, 136, 138 are used to receive the infrared light sources 131, 133' Light emitted by 135 '137. The position detecting device 1 is used in conjunction with a screen 111 on which the frame 11 is broken around the screen 111. When a finger or other object is placed at a certain position inside the frame 11 to block the infrared rays, part of the light receivers 132, 134, 136, 138 will not receive the light emitted by the infrared light sources 13i, 133, 135, 137. The position of the light receivers 132, 134, 136, 138 interrupted by light can determine the χ coordinates and 丫 coordinates of the object within the frame u. Specifically, when a certain object 15 is placed at a certain position in the frame η, the optical signals emitted by the infrared light source 13 133, 135 will be blocked, so that part of the light receivers 132, 134, 136 The intensity of the received optical signal at 138 is reduced. The intensity of the optical signals received by each of the light receivers 132, 134, 136, 138 is analyzed by a processor (not shown) and is based on the position of each of the light receivers 132, 134, 136, 138 and the received The intensity of the optical signal changes, and the position of the object under test 15 in the frame 11 is determined. As can be seen from the first figure, the intersection of the light lines 5 201030580 line receivers 132, 134, 136, 138 and the four sets of lines formed between each of the infrared light sources 13 133, 135 can determine the object to be tested 15 The position within η. SUMMARY OF THE INVENTION [0009] The object of the present invention is to provide a position detecting device and a detecting method thereof, which are capable of analyzing each image by capturing images of various angles in front of the screen.

": = (V :1 7,)..............................Formula (1) 0.03] ~(1) Vu (3) · ^(3) ] = [ 0.32 - 0.25 0.78 - 0.75 ] = [ 0.07 201030580 Formula (2) L1 = LsI7+AL1 ....................... ..... = [0.25 + 0.07 0J5 + 0.03 ] = t 〇32 〇?8] In the present invention - a method of using the sensing plane object 31 for $_^de image finding by the generator 27 is controlled. Image extraction unit ^K238 outside: You can also use the frequency to capture the position image of different angles. Therefore, the position image of the latest captured periodically and the previous one will be stored at the same time. The processing unit 25 compares the position image acquired by the second front, and according to the difference between the two, the position measured by the two time points ===2, the figure is the position detection disclosed in the present invention. Open the second to the seventh figure. The relevant method of measuring the system is as follows: · The position detection first uses 'the objects to be tested 33, 35 respectively at the specific position L1, L2 _ S8Q1) Click on 231~238 to treat the object 33, % mother-image operation unit according to the specific position U, L2 and plane (4) Like 'And come again, at 2 fc (step _)' · Yang Fan 25 will use the quantized bit sample position image conversion (4) value iSi to listen, like - the closest to the mother, Gui Si ((4)' $ and the object to be tested 25 can be processed from the corresponding relationship table 7 = the point of the point, the single-position image is processed, and the formula (1) is used = and the sampled sample is read), and finally, the image of the phase position in the processing unit (5) (The step image is calculated as 2::==” The corrected position is 疋伹罝L1, U (step S8〇9). 11 201030580 and its actual description of the position of the invention, the location of the test device, = one to 'can reduce the conventional Leiyang 々 hammer cover" know the road design, the hard panel in the eDonkey image The unit senses the image of each location, and the 'table correction' can achieve simultaneous detection of multiple touch bits J, who has more control modes. Further, the details of the specific embodiments are described in the following claims. All the scopes of the present invention should be clarified in the field of patents defined by the skilled person in the present invention.
