印刷電路板’亦可係為銦錫氧化物(jjjdiumTinOxideJTO)玻璃。於 此實施例’感測器300、觸控區域400與透鏡500可係位於液晶面 板700上。其中液晶面板700可係由ITO玻璃、液晶與濾光片等所 12 MJ/9764 組成。發光元件100可位於ITO玻璃(基板6〇〇)面向觸控區域400 的表面上。波導70件200可係鄰接發光元件1〇()，用以將發光元件 100所發出之光線經由入光面21〇入射至波導元件2〇〇内由波導 元件200將光線傳導至觸控區域4〇〇的一側邊上。由於ιτ〇玻璃上 具有傳導線路與電晶體以㈣液晶面板巾驗晶鋪。因此發 光元件100可係於ΙΤΟ玻璃的製程中一併製作於ΙΤ〇玻璃上。再利 用波導7L件200將波導元件200戶斤發出之光線傳導至液晶面板7〇〇 上，袁後使光線離開波導元件2〇〇並射出至觸控區域4〇〇。 根據本創作所揭露之光學觸控模組，將發光元件1〇〇製作於液 晶面板的ΙΤΟ玻璃(基板_)上，再利用波導元件將發光元件 100所發出之光線限制於波導元件200内傳遞’最後光線會出射離 開波導元件200並分佈於觸控區域4〇〇内。再由感測器3〇〇結合透 鏡5〇〇來接收觸控區域4〇〇内的所有光線。當手指或其他接觸物體 位於觸控區域400時，會遮斷部分由出光面22〇射出至觸控區域 的光線，感測器300在接收不到被遮斷光線後，會進而判斷手指或 其他接觸物體位於觸控區域400的相對位置。於此，藉由將發光元 件100製作於基板600上，再利用波導元件2〇〇將發光元件1〇〇所 發出之光線均勻分佈至觸控區域400，可降低光學觸控模組的厚 度，同時減少將發光元件另行製作於印刷電路板上等的成本。 第5圖係為根據本創作第五實施例之波導元件與發光元件鄰接

200b將光線傳導至觸控區域的相鄰兩側邊。於此，藉 由將發光元件1〇〇製作於基板_上，並由波導元件的入光面 210接收發光元件100所發出之光線。光線在波導元件2⑻内會分 別由兩子波導元件200a、200b將光線傳導至觸控區域4〇〇的相鄰兩 側邊並射出至觸控區域4〇〇。如上所述，可降低光學觸控模組的厚 度，同時減少將發光元件另行製作於印刷電路板上等的成本。根據 本創作所揭露之光學觸控模組，藉由波導元件2〇〇將發光元件1〇〇 所發出之光線均勻分佈至觸控區域400，可增加光學觸控模組對環 境光源的抵抗能力、降低發光元件1〇〇的發光亮度、減少電流損耗 以及光學觸控模組的對位精準度。 請參考第6圖。第6圖係為說明根據本創作之第六實施例之波 導模組800之示意圖。波導模組800可應用於本創作所述之光學觸 控模組。波導模組800係根據前述之波導元件200加以改良，以將 發光疋件1〇〇所提供之光線作更有效率的利用，並同時將光線均勻 分佈至觸控區域4〇〇。波導模組800包含一波導元件81〇，以及—聚 光兀件820。波導元件810之結構以及工作原理與前述之波導元件 2〇〇類似。波導元件81〇用來引導光線沿著波導元件81〇擴散，波 M379764 導元件810包含一入光面811以及-出光面812，入光面811面向 發光7G件100以接收光線。出光面812面向觸控區域4〇〇。聚光元 件820，用來匯聚從出光面812所射出之光線，以使光線集中散佈 於觸控區域。此外，#發光耕勘係為紅外光發光二極體(也 就是說，發光元件1〇〇發出紅外光時），聚光元件㈣係為可透紅外 ^ 光之透鏡。 ' 聲 請參考第7圖、第8圖、第9圖、第1〇圖，以及第u圖。第 7圖係為說明當光線從波導元件·直接射出至觸控區域之示 意圖。第8圖、第9圖、第1〇圖，以及第u圖係為說明藉由不同 結構之聚光元件820，波導模組800可將發光元件1〇〇所提供之光 線作更有效率的利用之工作原理之示意圖。·由第7圖可看出，由於 當發光元件100所提供之光線直接從波導元件200射出時，光線之 強度係大約呈朗伯分佈(lambertiandistribution)，也就是說，當光線 從波導元件200射出時，光線會在各方向上皆均勻散射。然而，由 •於從波導元件2〇〇射出之光線會均勻分佈於垂直方向上，因此表示 部份光線直接遠離觸控區域4〇〇(舉例而言，如第7圖所示之光線 LA) ’以及部份光線被基板600反射後，而遠離觸控區域4〇〇(舉例而 言，如第7圖所示之光線LB)。換句話說，發光元件1〇〇所提供之 光線無法集中於觸控區域400。如此，感測器3〇〇可接收到之光線 之能量較少’因此表示感測器300所接收之訊號之訊雜比降低，而 造成光學觸控模組較不易判斷手指或接觸物之位置。如第8圖、第 9圖、第10圖’以及第11圖所示，聚光元件82G可為凸凹透鏡、 15 MJ/y/04 平透i凸凸透鏡，或是平喊鏡。更明確地說 1-凸凹透鏡時(如第8 _示），該凸凹透鏡响 犯，且該凸凹透鏡之凹面面向觸控區面 =;=82°為，透鏡時(如第11心： 且ΓΓ

也不會因被基板600反射後，而遠離觸控區域4〇〇。如此一來，發 光το件100所提供之光線可集中於觸控區域4〇〇,而提高感測器· 所接收到之光線之能量，也就是說，提高感測器3〇〇所接受之訊號 之訊雜比。因此’光箱減組可更正確地騎手指或接觸物之位 置。 請參考第12圖。第12圖係為說明根據本創作之第七實施例之 波導模組900之示意圖。相較於波導模組8〇〇，波導模組9〇()另包 含有一固定元件(holder)930，耦接至聚光元件820。固定元件930 係用來包覆波導元件810,以將波導模組900固定於基板600之上。 16 M379764 此外’在第12 ®之聚光元件82〇係以凸凹透鏡作為舉例，然而聚光 元件820也可為凸平透鏡、凸凸透鏡，或是平凹透鏡。 請參考第13圖。第13圖係為說明藉由如前述之波導元件包含 反射面之設計，波導模組800可引導發光元件1〇〇所提供之光線從 觸控區域400之多個不同之侧邊射入觸控區域4〇〇之示意圖。在第 13圖中’波導模组8〇〇之波導元件⑽另包含一反射面。反射 面815之結構與工作原理與反射面25〇類似。反射面815位於波導 兀件810之轉折處。反射面815，用來使光線能經由反射面815以 在波導元件810内反射而不經由波導元件81〇之轉折處射出。換句 話說，藉由反射面815之設計’波導模組800可設置於觸控區域4〇〇 的多個側邊。舉例而言，在第13圖中，波導模組8〇〇係設置於觸控 區域400之三個側邊。如此一來，表示在光學觸控模組中，僅需要 一發光元件(1〇〇)以及一波導模組(8〇〇)，即可將光線從觸控區域4〇〇 之多個不同之侧邊導入觸控區域4〇〇，而使光線均勻地散佈至觸控 區域中。此外，與波導元件2〇〇類似，波導元件81〇的形狀，可為 一楔型結構(如第1圖〜第3圖所示，靠近發光元件100的一端較厚， 遠離發光元件100的一端較薄），也可為一平板結構(如第13圖所示)。 請參考第14圖。第14圖係為說明波導元件81〇之結構之示意 圖。波導元件810另包含一導光條813，以及一反射元件814。如第 14圖所不，導光條813之表面8131用來作為入光面811。因此，導

反射回導光條813。因此，最後，光線Lc從出光面812(導光條813 之表面8132)射出。 請參考第15圖。第15圖係為說明波導元件之結構之另一實施 例1000之示意圖。相較於第14圖之波導元件810，波導元件1〇〇〇 另包含一轉向結構1010。轉向結構1〇1〇係用來將入光面8ιι轉置 為面向基板600，並將自入光面811所接收之光線轉向為平行於基 板’以將光線引導至導光條813。更明確地說，藉由轉向結構ι〇ι〇， 在波導元件1000中，入光面811可面向基板6〇〇。因此，發光元件 1〇〇可直接設置在基板600上，而不需透過其他連接器以將發光元 件1〇〇所提供之光線轉向。舉例而言，在第15圖中，轉向結構ι〇ι〇 係為將反射元件814與導光條813轉折以形成一三角形之結構，當 發光兀件100所提供之一光線Ld向上方射入轉向結構1〇1〇時，光

New description: [New technology field] The wave of the optical touch module is related to a waveguide module. In particular, it is applicable [previous technology] In recent years, touch screen (also known as touch panel) Because you can directly use the object or hand threat _, and directly touch the direct directly in the county to hide and cut. When using the program, turn to various county settings, and display vivid video effects by recording the picture.算 算 ΓΓ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ When in use, the upper and lower electrodes are turned on by using pressure to measure the voltage change on the camp=============================== Capacitor Extraction Control is the change of capacitance generated by the electrostatic combination between the transparent electrode and the human body, and the coordinates are detected from the induced current generated. The acoustic wave touch wire is converted into ultrasonic waves by using the electric signal in advance, and directly transmits the surface of the manuscript control panel. When the touch panel is used, the gambling age is supersonic and the silk is reduced, and the sisters use the amount of sorrow before and after use. The exact position is obtained after calculation. Optical touch recording is the principle of receiving light from the paste source. When the light is blocked, it can know that the position of the signal receiver is not received, and then the precise position is determined. The components of the optical touch screen include a glass substrate, a light emitting device, a light receiver, and a lens. The device is arranged to arrange the light-emitting device and the light receiver on the upper right corner of the glass substrate, and to reflect the strip on the left side and the lower side of the glass substrate. Illuminating the distal reflective strip via the illumination device, the light receiver can collect through the lens when the finger or contact blocks the light* to the relative position of the finger or contact on the glass substrate. The optical touch screen of S knows that it is easy to be affected by the ambient light source because the reflective strip is used to reflect the light emitted by the light-emitting device to detect the relative position of the finger or the contact on the glass substrate. The light reflected by the same reflective strip and the light emitted by the illumination device can have an interactive effect on the optical receiver. In addition, since the illuminating device placed on the upper right corner of the glass substrate must illuminate the reflective strip at the far end, a more accurate alignment and a large output brightness and output current are required.

[Embodiment] FIG. 1 is a plan view of an optical touch module according to a first embodiment of the present invention. Referring to FIG. 1, in this embodiment, the optical touch module can be located on a display screen such as a screen of a liquid crystal display, a screen of a cathode ray tube display, an electronic whiteboard, or the like. The optical touch module includes a touch area 4A, a sensor 300, a light emitting element 100', and a waveguide element 200. The sensor 300 is disposed at a corner of the touch area 400. The number of the light-emitting element 100, the waveguide element 200, and the sensor 300 may be one or two or more. For convenience of explanation, in this embodiment, the number of the light-emitting elements ι is one, the number of the waveguide elements 2GG is two, and the number of sensing n 300 is one', but is not limited thereto. The waveguide element 2 is disposed on at least one side of the touch area. The touch area 400 may be a polygon (such as a quadrangle, a pentagon or a hexagon), and the waveguide element 2 is disposed on a side of the touch area 4〇〇 of the polygon. The waveguide τ 2 member 2 can include a light incident surface 21 〇 and a light exit surface 22 。. The incident light 'face 210 may be facing the light-emitting element 1'. In other words, the light incident surface 21 can be adjacent to the optical light element 1 , that is, the light incident surface 210 can be attached to the light emitting surface of the light emitting element 1 • or the light incident surface 210 and the light emitting element The hairline of 100 is correspondingly spaced. The light exit surface 220 can face the touch area 4〇〇. The optical touch module may further include a lens 5 () (). The lens pass may correspond to the sensor 300. The lens 500 can be located between the corresponding sensor 3〇〇 and the touch area 4〇〇. The lens 500 can be adjacent to the sensor 3, that is, the lens 5 can be connected to the wire receiving surface of the sensor, or the lens, the squirrel. The light emitting element 100 can be located at a corner of the touch area 400 opposite to the sensor 3〇〇. The touch area 400 of this embodiment may be rectangular (quadrilateral). The sensor 3A can be disposed at a corner of the touch area 400. At this time, the light-emitting element 1A can be disposed at the same or different corners of the touch area 400 as the sensor 300. In other words, the sensor 3A can be disposed at a corner of the touch area 400, and the light emitting element 1 can be disposed at a corner of the touch area 400 opposite to the sensor 300, wherein the light emitting element 1 is disposed at The corner position of the touch area M379764 400 relative to the sensor 300 may be that the light-emitting element 1 is disposed at an adjacent angular position adjacent to the sensor 300, or the light-emitting element may be disposed opposite to the sensor. Corner position. When the light-emitting elements 1 are disposed at opposite diagonal positions from the sensor 3, the two waveguide elements 2 (8) may be respectively disposed on both sides of the touch area 4 相邻 adjacent to the light-emitting element drain. on. The shape of the waveguide element 2'''''''''''''''''''''''''''''''' The touch area 4〇〇 may also be a polygon of a pentagon or more. In this case, the light-emitting element may be disposed at an adjacent position adjacent to the sensor 300, or may be disposed and sensed by the light-emitting element hall. H 3 (8) spaced adjacent corners, more preferably the light-emitting element is just placed at a diagonal position opposite to the sensing benefit 300. The illuminating element 100 can be used to generate light and provide light to exit the illuminating element (10). The light emitted by the light-emitting element 100 may be infrared light visible light or the like. The light-emitting element 100 can be an infrared light-emitting diode, a light-emitting diode, or the like. Luguang 210 can be used to receive light emitted by the illuminating elements. The shape of the light incident surface 210 may correspond to the shape of the light emitting element i (8). Wherein, the light-incident surface 21 can be used as a light/moon surface to prevent the light emitted by the light-emitting element (10) from being emitted by the light surface 21〇, which may cause light scattering due to the coarse wheel on the surface of the light-incident surface 210. The efficiency of light incident on the light surface 210 is reduced. 8 After entering the waveguide element by the light entrance surface 210, her light is passing. Light surface _ to provide light leaving the wave == structure. When the diffused junction system is a grating structure or an irregular structure and is emitted from a clear light to a diffused structure, it is no longer due to total reflection =! ,, but the light is emitted from the waveguide through the diffusion structure. The structure may be such that when the waveguide component is fabricated, the shape of the diffusion structure and the position of the diffusion structure are designed on the mold. Therefore, when the waveguide element 200 is injection molded or formed, the diffusion structure is located on the light exit surface 22〇. The diffusion structure may also be formed by forming a brazing element 2 into a bump, processing (sanding, etc.) to form a diffusion structure thereon. The lens is used to increase the light-receiving angle A' of the sensor 3', that is, the lens 5's original light-receiving angle can receive light of a larger angle range. Taking the embodiment as an example, the touch area is a rectangle (quadrilateral), and the four corners of the touch area 4 are all 9 degrees. Generally, the light receiving angle of the sensor 3〇〇 is less than 90 degrees. Therefore, when the sensor 3 is disposed at a corner of the touch area 4〇〇, only the light within a local angle range can be received, and the touch cannot be received. Control all the light in the area 4〇〇. Therefore, when the finger or other contact object is located in the touch area 4〇Cj and is outside the range of the light receiving angle of the sensor 300, the sensor 3〇〇 cannot sense the relative position of the finger or other contact object in the touch area 400. Therefore, by providing the lens 500 between the sensor 300 and the touch area 400, the range of the light receiving angle of the sensor 30 is increased. In this embodiment, the sensor 3 can pass through the lens 5.感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感 感The light is received at a wide angle of 9 degrees, so that all the light in the touch area 400 can be received by a sensor in combination with the lens 5 . According to the optical touch module disclosed in the present invention, when the light-emitting element emits light, the light-emitting surface 210 of the two waveguide elements 200 facing the light-emitting element 100 is first received by the light-emitting element. The light is confined to the two waveguide elements by the difference in refractive index between the waveguide element and the outside air. Finally, the left light is separated from the two waveguide elements 2 by the diffusion structure of the light exit surface 220 and distributed in the touch area 400. Inside. Then, the sensor 3 is combined with the lens 5 to receive all the light in the touch area. When the finger or other contact object is located in the touch area 4 (8), the light emitted from the light exit surface 220 to the touch area 4〇〇 is blocked, and the sensor 3 is not received after the blocked light is received. Further, it is determined that the finger or other contact object is located at a relative position of the touch area 400. Herein, the light emitted by the light-emitting element 1 (nine) is evenly distributed to the touch area 4〇〇 by the two waveguide elements 2〇〇, instead of using the light-reflecting strip to reflect the light emitted by the light-emitting element 7C. The optical touch module can increase the resistance to the ambient light source, and avoid the interaction between the light emitted by the conventional light-emitting element 1 and the light reflected by the reflective strip on the sensor 300. At the same time, the brightness of the light-emitting element 100 can be reduced, the current loss can be reduced, and the alignment accuracy of the optical touch module can be achieved. 2 is a top view of the optical touch module according to the second embodiment of the present invention. Please refer to Fig. 2 for reference to the foregoing embodiment. In this embodiment, the two waveguide elements 2 can also be disposed on one side of the touch M379764 region 400 adjacent to the light-emitting element 1A. The other of the two waveguide elements is disposed on the other side of the touch area 4A adjacent to the light-emitting element 100, wherein the end away from the light-emitting element 100 extends along the corner of the touch area 40 (four) A diagonal position opposite the brain spacing of the illuminating element. In the waveguide element in which the turning extends to a diagonal position opposite to the light-emitting element 100, a reflecting surface 250 can be formed at the position of the turning, and the light can be transmitted to the light-emitting element through the reflection surface in the fine reflection of the waveguide element. • Diagonal positions relative to each other. In this case, the light emitted by the illuminating element is transmitted to the three sides of the touch area 400 by the two waveguide elements 200, and the light is emitted by the waveguide element and evenly distributed in the touch area to replace the light. It is known that using the reflective strip to reflect the light emitted by the 2 element 100 can increase the resistance of the optical touch module to the ambient light source, and avoid the light emitted by the conventional light-emitting element (10) and the light reflected by the reflective strip to the sensor 300. The interaction caused. At the same time, it can achieve the reduction of the luminous party of the light-emitting element touch, reduce the current loss and the accuracy of the light_holding_alignment. Figure 3 is a plan view of the optical touch module according to the third embodiment of the present invention. Please refer to Fig. 3' for reference to the foregoing embodiment. In this embodiment, the optical touch module can include two light emitting elements 100 and three waveguide elements 200. In this embodiment, the touch area 4〇0 can be rectangular (quadrilateral). The sensor 3 is disposed at a corner of the touch area, and one of the two light-emitting elements is disposed at a corner of the touch area 400 opposite to the sensor 300, and the other of the two light-emitting elements 100 is set. The touch area 400 is adjacent to a corner of the sensor 300. The three waveguide elements 200 can be disposed on the side of the touch area between the two light-emitting elements. Two of the three waveguide elements 2〇0 are respectively disposed on the other side 11 of the touch area 400 adjacent to the light emitting element 100. According to the present invention, the silk touch module, t, will be directed to face each of the light-emitting elements 10. The second input " face 210 receives the light emitted by the parent-light-emitting element. By the difference of the refractive index of the external component of the waveguide element, the light is confined to the three waveguide elements, and finally the light leaves the three waveguide elements through the diffusing structure of the light exiting surface and is distributed in the touch area gamma. All the light in the touch area 400 is received by the sensor in combination with the lens. When the finger or other contact object is located in the touch area, the light that is emitted from the light exit surface 22 to the touch area is blocked. After sensing the light of the task, the sensor 300 will reduce the relative position of the other contact objects in the touch area 4GG. Here, the light emitted by the two light-emitting elements 100 is uniform by the three waveguide elements. Distributed to the touch area · for use. It is known that the use of reflective strips to reflect the light emitted by the light-emitting elements can increase the resistance of the optical touch module to the ambient light source, and avoid the conventional light-emitting elements. The interaction between the emitted light and the light reflected by the reflective strip on the sensor 3 。. At the same time, the illuminating brightness of the illuminating element 1 降低 is reduced, the current loss is reduced, and the optical The alignment accuracy of the touch module. Fig. 4 is a side view of the optical touch module according to the fourth embodiment of the present invention. Please refer to Fig. 4 for the reference to the foregoing embodiment. In this embodiment, the optical touch The control module includes a substrate 600. The substrate 600 can be located under the touch area 400. The substrate 600 can be a printed circuit board or can be an indium tin oxide (JJJdium TinOxide JTO) glass. In this embodiment, the sensor 300, The touch area 400 and the lens 500 can be located on the liquid crystal panel 700. The liquid crystal panel 700 can be composed of 12 MJ/9764, such as ITO glass, liquid crystal and filter. The light emitting element 100 can be located on the ITO glass (substrate 6 〇〇). ) facing the surface of the touch area 400. The waveguide 70 piece 200 may be adjacent to the light emitting element 1 〇 ( ) for injecting light emitted by the light emitting element 100 into the waveguide element 2 through the light incident surface 21 由 by the waveguide The component 200 conducts light to one side of the touch area 4. The light-emitting element 100 can be attached to the glass-lined process because of the conductive line and the transistor on the glass. Also produced in Yubo Then, the waveguide 7L member 200 is used to conduct the light emitted from the waveguide element 200 to the liquid crystal panel 7〇〇, and the light causes the light to leave the waveguide element 2 and emit the light to the touch region 4〇〇. In the disclosed optical touch module, the light-emitting element 1 is fabricated on the glass substrate (substrate_) of the liquid crystal panel, and the light emitted by the light-emitting element 100 is confined in the waveguide element 200 by the waveguide element to transmit the last light. The light exits the waveguide element 200 and is distributed in the touch area 4〇〇. The sensor 3〇〇 combines the lens 5〇〇 to receive all the light in the touch area 4〇〇. When the finger or other contact object is located When the area 400 is controlled, the light emitted from the light-emitting surface 22 to the touch area is blocked. After receiving the blocked light, the sensor 300 further determines that the finger or other contact object is located in the touch area 400. relative position. In this case, by forming the light-emitting element 100 on the substrate 600 and then distributing the light emitted by the light-emitting element 1 to the touch region 400 by using the waveguide element 2, the thickness of the optical touch module can be reduced. At the same time, the cost of separately manufacturing the light-emitting element on the printed circuit board or the like is reduced. Fig. 5 is a schematic view showing a vicinity of a waveguide element and a light-emitting element according to a fifth embodiment of the present invention. As shown in Fig. 5, reference is made to the fourth embodiment. In this embodiment, the wave 13 guiding member 200 may have a receiving area for accommodating the leakage of the light emitting element at one end, and the other end is divided into two sub-waveguide elements 2〇〇a and 2〇〇b respectively facing the touch area. The shape of the accommodating area in which the light-emitting elements 1 谷 are disposed on the two sides of the adjacent side may correspond to the shape of the light-emitting element and the inner wall of the accommodating area is the light-incident surface 21 〇. The light line b emitted from the light-emitting element 1 is transmitted through the light-incident surface 21 to the waveguide element 2, and the two sub-waveguides a 200b of the waveguide element conduct light to the adjacent side edges of the touch area. Here, the light-emitting element 1 is fabricated on the substrate_, and the light emitted from the light-emitting element 100 is received by the light-incident surface 210 of the waveguide element. The light rays are conducted by the two sub-waveguide elements 200a, 200b in the waveguide element 2 (8) to the adjacent two sides of the touch area 4A and are emitted to the touch area 4A. As described above, the thickness of the optical touch module can be reduced, and the cost of separately manufacturing the light-emitting element on the printed circuit board can be reduced. According to the optical touch module disclosed in the present invention, the light emitted by the light-emitting element 1 is evenly distributed to the touch area 400 by the waveguide element 2, thereby increasing the resistance of the optical touch module to the ambient light source. The illumination brightness of the light-emitting element 1 降低 is reduced, the current loss is reduced, and the alignment accuracy of the optical touch module is reduced. Please refer to Figure 6. Fig. 6 is a schematic view showing a waveguide module 800 according to a sixth embodiment of the present invention. The waveguide module 800 can be applied to the optical touch control module described in the present application. The waveguide module 800 is modified in accordance with the waveguide element 200 described above to more efficiently utilize the light provided by the illuminating element 1 while distributing the light evenly to the touch area. The waveguide module 800 includes a waveguide element 81A and a collector element 820. The structure and operation of the waveguide element 810 are similar to those of the waveguide element 2 described above. The waveguide element 81 is used to guide the light to diffuse along the waveguide element 81. The wave M379764 is provided with a light incident surface 811 and a light exiting surface 812. The light incident surface 811 faces the light emitting 7G member 100 to receive light. The light emitting surface 812 faces the touch area 4〇〇. The concentrating element 820 is configured to converge the light emitted from the light emitting surface 812 to concentrate the light on the touch area. In addition, the illuminating illuminating system is an infrared light emitting diode (that is, when the illuminating element 1 〇〇 emits infrared light), and the concentrating element (4) is an infrared permeable lens. ' Sound Please refer to Figure 7, Figure 8, Figure 9, Figure 1, and Figure u. Fig. 7 is a view for explaining the direct emission of light from the waveguide element to the touch area. 8 , 9 , 1 , and u are diagrams illustrating that the waveguide module 800 can more efficiently illuminate the light provided by the light-emitting element 1 by using the concentrating element 820 of different structures. A schematic diagram of the working principle of utilization. As can be seen from Fig. 7, since the light provided by the light-emitting element 100 is directly emitted from the waveguide element 200, the intensity of the light is approximately a lamberian distribution, that is, when the light is emitted from the waveguide element 200. When the light is evenly scattered in all directions. However, the light emitted from the waveguide element 2 is uniformly distributed in the vertical direction, so that part of the light is directly away from the touch area 4 (for example, the light LA as shown in FIG. 7). And some of the light is reflected by the substrate 600 away from the touch area 4 (for example, the light LB as shown in Fig. 7). In other words, the light provided by the light-emitting element 1〇〇 cannot be concentrated on the touch area 400. In this way, the energy of the light received by the sensor 3〇〇 is less, thus indicating that the signal-to-noise ratio of the signal received by the sensor 300 is reduced, and the optical touch module is less likely to determine the position of the finger or the contact object. . As shown in Fig. 8, Fig. 9, Fig. 10, and Fig. 11, the concentrating element 82G may be a convex-concave lens, a 15 MJ/y/04 translucent i convex lens, or a flat mirror. More specifically, when a convex-concave lens is used (as shown in FIG. 8), the convex-concave lens is slammed, and the convex surface of the convex-concave lens faces the touch area == 82° is the lens (such as the 11th heart: ΓΓ 12, and the concave surface of the plano-concave lens faces the touch area 400. As can be seen from FIG. 8, FIG. 9 and FIG. H), and the U-picture, the concentrating element _ concentrating from the waveguide element 810 The light emitted by the light-emitting surface 812 can cause the first line to be close to the right of the touch area. Therefore, compared with the waveguide element 200, the waveguide module 800 converges the light emitted from the light-emitting surface 812 by the concentrating element 82, so that the light provided by the illuminating element 1 is not directly away from the touch area. It is also away from the touch area 4〇〇 after being reflected by the substrate 600. In this way, the light provided by the illuminating device 100 can be concentrated on the touch area 4〇〇, and the energy of the received light of the sensor is improved, that is, the sensor 3 is improved. The signal ratio of the signal. Therefore, the light box reduction group can more accurately ride the position of the finger or the contact object. Please refer to Figure 12. Figure 12 is a schematic view showing a waveguide module 900 according to a seventh embodiment of the present invention. The waveguide module 9A () further includes a holder 930 coupled to the concentrating element 820. The fixing member 930 is used to cover the waveguide member 810 to fix the waveguide module 900 on the substrate 600. 16 M379764 Further, the concentrating element 82 of the 12th is exemplified by a convex-concave lens, but the concentrating element 820 may also be a convex flat lens, a convex convex lens, or a plano-concave lens. Please refer to Figure 13. FIG. 13 is a view showing that the waveguide module 800 can guide the light provided by the light-emitting element 1 to be touched from a plurality of different sides of the touch area 400 by using a design of the waveguide element as described above. A schematic diagram of the area 4〇〇. In Fig. 13, the waveguide element (10) of the waveguide module 8 further includes a reflecting surface. The structure and working principle of the reflecting surface 815 is similar to that of the reflecting surface 25〇. The reflecting surface 815 is located at the turning point of the waveguide element 810. Reflecting surface 815 is used to enable light to be reflected within waveguide element 810 via reflective surface 815 without exiting through the corners of waveguide element 81. In other words, the waveguide module 800 can be disposed on the plurality of sides of the touch area 4 by the design of the reflective surface 815. For example, in FIG. 13, the waveguide module 8 is disposed on three sides of the touch area 400. In this way, in the optical touch module, only one light-emitting element (1〇〇) and one waveguide module (8〇〇) are needed, so that the light can be separated from the touch area 4 by a plurality of different ones. The side is introduced into the touch area 4〇〇, and the light is evenly distributed into the touch area. Further, similar to the waveguide element 2〇〇, the shape of the waveguide element 81〇 may be a wedge-type structure (as shown in FIGS. 1 to 3, the one end near the light-emitting element 100 is thicker, away from the end of the light-emitting element 100. Thinner) can also be a flat structure (as shown in Figure 13). Please refer to Figure 14. Fig. 14 is a schematic view showing the structure of the waveguide element 81. The waveguide element 810 further includes a light guide strip 813 and a reflective element 814. As shown in Fig. 14, the surface 8131 of the light guiding strip 813 is used as the light incident surface 811. Therefore, the surface 8131 of the light guiding strip 813 faces the light emitting element 1A. The surface 8132 17 M379764 of the light guiding strip 813 is used as the light emitting surface m. The reflective element _ is covered with a light guide strip. The reflecting element is configured to reflect the light emitted from the surface (10) of the light-emitting surface light guiding strip 813 back to the light guiding strip 813' so that the light guiding material of the waveguide element (4) is called the surface 8132 of the light guiding strip 813 from the light emitting surface. ) into the touch area 4〇〇. For example, when the light ray LC in Fig. 14 is incident on the surface 8133 of the light guiding strip 813, the light & is reflected back to the light guiding strip 813 by the reflecting element 814. Therefore, finally, the light ray Lc is emitted from the light-emitting surface 812 (the surface 8132 of the light guiding strip 813). Please refer to Figure 15. Fig. 15 is a schematic view showing another embodiment 1000 of the structure of the waveguide element. The waveguide element 1 〇〇〇 further includes a steering structure 1010 as compared to the waveguide element 810 of FIG. The steering structure 1 〇 1 用来 is used to transpose the light-incident surface 8 ι to face the substrate 600 and divert the light received from the illuminating surface 811 parallel to the substrate ‘ to guide the light to the light guiding strip 813. More specifically, in the waveguide element 1000, the light incident surface 811 can face the substrate 6A by the steering structure ι〇ι〇. Therefore, the light-emitting element 1 can be directly disposed on the substrate 600 without passing through other connectors to steer the light provided by the light-emitting element 1 . For example, in FIG. 15, the steering structure ι〇ι〇 is a structure in which the reflective element 814 and the light guiding strip 813 are turned to form a triangular structure, and one of the light rays Ld provided by the light emitting element 100 is incident upward. When the steering structure is 1〇1〇, the light LD passes through the light guiding strip 813 first, and then is reflected by the portion of the steering structure 1〇1 that belongs to the reflecting element 814, and turns to the right. Further, since the waveguide element is in a flat shape, the area of the surface 8131 (light incident surface 811) of the light guiding strip 813 in Fig. 14 is extremely small. Thus, the light supplied from the light-emitting element 100 cannot be efficiently incident on the surface 8131 (light-incident surface 811) of the light guiding strip 813. However, in Fig. 15, since the light incident surface 811 of the steering structure 1_ can be faced to the substrate _ by 18, even if the waveguide element is drawn in a flat shape, the area of the light incident surface 811 is not limited. Thus, the area of the light incident surface 811 can be designed to be large enough to effectively receive the light provided by the light-emitting element. Referring to Figure 16 and Figure 16 of the month, the pure _ of the hard-to-face surface of the optical touch module using the waveguide module is illustrated. The wire-hard module brain includes a touch area 161G, a sensor 162A, a light-emitting element 163(), and a waveguide module 1640. The sensor 162 is located at one of the first corners of the touch area 161 (in the fourth (in the fourth), the upper right corner is taken as an example). The light-emitting element 163 is disposed on one of the first side of the touch area 161 (in the 16th figure, the left side is exemplified) for providing light. The waveguide module 1640' is disposed on three sides of the touch area 161 to uniformly distribute the light provided by the light-emitting element 至 to the touch area 161. The waveguide module 640 is implemented by using the structure of the waveguide module described in FIG. 6 to FIG. 15 , and the light incident surface of the waveguide component of the waveguide module 1640 can face the substrate below, so that the light emitting element 163 can be directly disposed on The substrate corresponds to the position of the light incident surface of the waveguide element of the waveguide module 1640. In this manner, the light provided by the light-emitting element 1630 can be concentrated by the waveguide element 164 and the concentrating element to concentrate on the touch area 1610, thereby increasing the signal-to-noise ratio of the signal received by the sensor 1620. Therefore, the optical touch module 16 can more accurately determine the position of the finger or the contact. In addition, in FIG. 6 , the optical touch module 16 〇〇 includes only one light-emitting element 1630 as an example. By the design of the reflective surface 815 of the waveguide element 810 , the waveguide module 1640 can provide the light-emitting element 1630 . The light guides the three sides of the touch area 161 into the touch area 161 (however, when the position of the light element 19 M379764 of the optical touch module 16 changes, the optical touch group The number of positions of the lion scale pool can also be correspondingly designed according to the foregoing description. For example, the optical touch module 1_ can be implemented in a manner similar to the 帛i diagram, that is, the two waveguide mode components are set in touch. Controlling both sides of the area, and receiving the light provided by the same light-emitting element to guide the light from the two (four) of the touch area; the wire touch-laying surface can also be implemented by means of Figure 2, that is, The three waveguide modules are respectively disposed on the three sides of the touch area to guide the three sides of the personal touch area provided by the two light-emitting elements; or the optical touch module 1600 can also be simplified (4) Method implementation, that is, a first waveguide module set The first side (left side), the second waveguide module is designed by the reflective surface to set the second side (lower side) and the third side (right side) of the Wei domain - Receiving light from the same light-emitting element with the second waveguide module and directing light from the first, second, and third sides of the touch area to the touch area. Chi, can be thinner than the silk touch module. The waveguide of this creation, the light emitted from the material component by the concentrating component can be concentrated on the touch area of the optical touch module. The light provided by the illuminating element can effectively increase the signal-to-noise ratio of the signal of the ❹m. Therefore, the optical touch module can more accurately determine the position of the finger or the contact object. The group, by the design of the steering structure, can make the human silk face the substrate. Therefore, the area of the human filament is relatively free of _, and the light provided by the illuminating element can be effectively received, and the component can be woven on the button. More convenient. The above is only for reading good _, Fan Yiyi creation ^ The equal changes and modifications made in the scope of patents 20 shall fall within the scope of this creation.
