Description

光学触控装置 The optical touch device

技术领域 FIELD

[0001] 本发明是关于一种触控装置,且特别是关于一种光学触控装置。 [0001] The present invention relates to a touch device, and more particularly relates to an optical touch device.

背景技术 Background technique

[0002] 光学触控装置是常用的实现触控功能所需的电子元件之一。 [0002] The optical touch device is one of the electronic components required to achieve the common touch function. 图1是现有的一种具有三个影像感测元件的光学触控装置的结构示意图。 FIG 1 is a schematic view of a conventional optical touch device having three image sensing elements. 请参照图1,现有的光学触控装置100包括沿矩形轨迹的四个边依次排列的反光条112a、112b、112c、112d。 Referring to FIG. 1, a conventional optical touch device 100 includes a reflective tape along four sides of the rectangular trajectory sequentially arranged 112a, 112b, 112c, 112d. 光学触控装置100还包括发光元件122a、122b、122c,用以提供光线至反光条112a、112b、112c、112d,其中发光元件122a设置于反光条112a与反光条112b的相邻两端之间,发光元件122b设置于反光条112b与反光条112c的相邻两端之间,而发光元件122c设置于反光条112a与反光条112d的相邻两端之间。 The optical touch device 100 further includes a light emitting element 122a, 122b, 122c, for providing light to the reflective strips 112a, between 112b 112c, 112d, wherein ends of adjacent light-emitting element 122a and 112a provided in the reflective tape is reflective strip 112b , disposed between the light emitting element 122b adjacent reflective tape ends 112b and 112c of reflective strips, and between the light emitting element 122c disposed at both ends of an adjacent reflective strips 112a and 112d of the reflective strip. 反光条112a、112b、112c、112d用以反射发光元件122a、122b、122c提供的光线。 Reflective strips 112a, 112b, 112c, 112d for reflecting the light emitting elements 122a, 122b, 122c provided light. 另外,光学触控装置100还包括影像感测元件132a、132b、132c,其中影像感测元件132a设置于反光条112a与反光条112b的相邻两端之间,且发光元件122a配置于影像感测元件132a上。 Further, the optical touch device 100 further includes an image sensing element 132a, 132b, 132c, 132a in which the image sensing element disposed between adjacent reflective tape ends 112a and 112b of the retroreflective article, and the light emitting element 122a disposed on the image sensor sensing element 132a. 影像感测元件132b设置于反光条112b与反光条112c的相邻两端之间,且发光元件122b配置于影像感测元件132b上。 Image sensing element 132b is disposed between the ends of adjacent reflective tape strip 112b and 112c of the reflector, and the light emitting element 122b disposed on the image sensing element 132b. 影像感测元件132c设置于反光条112a与反光条112d的相邻两端之间,且发光元件122c配置于影像感测元件132c上。 Image sensor 132c disposed between adjacent ends with reflective tape reflective strips 112d, 112a, 122c and the light emitting element is disposed on the image sensing element 132c.

[0003] 但是,光学触控装置100存在一定的盲区(blind zone)。 [0003] However, the optical touch device 100 there is a certain blind (blind zone). 举例来说,如图1所示,影像感测元件132b的视野(field of view, FOV)涵盖反光条112a、112d,但反光条112a与反光条112d之间存有间隙以设置影像感测元件132c。 For example, as shown in FIG. 1, the image sensing element 132b of the field of view (field of view, FOV) covering reflective strips 112a, 112d, 112d, but a gap between the reflective tape there and reflective strips 112a is provided to the image sensing device 132c. 由于影像感测元件132c无法反射光线,导致影像感测元件132b无法感测到在区域150内的触控点C,所以区域150即为所谓的盲区。 Since the image sensing element 132c can not reflect light, resulting in an image sensing element 132b can not sense touch point C in region 150, region 150 is the so-called blind spot. 另外,影像感测元件132c在感测时也有类似的盲区问题。 Further, in the image sensing element 132c is sensed blind have similar problems.

[0004] 为了解决上述问题,现有的常用的解决办法是利用影像感测元件轮流感测并搭配发光元件进行补光。 [0004] In order to solve the above problems, a conventional solution is to use conventional image sensing element and the sensing wheel with the light emitting element fill light. 举例来说,当影像感测元件132b进行感测时,发光元件122a、122b提供正常亮度的照明光线,而发光元件122c则提供亮度较暗的补偿光线,以进行补光,进而使反光条112a与反光条112d之间的间隙的亮度与反光条112a、112d的亮度相似,如此可解决盲区的问题。 For example, when the image sensing element 132b for sensing the light emitting elements 122a, 122b to provide normal luminance illuminating light, and the light emitting element 122c provides a darker luminance compensation light to fill light, thereby enabling the reflective strips 112a and the gap between the luminance and reflective strips similar brightness reflective strips 112a 112d, 112d, and thus solve the problem of the blind spot. 同理,当影像感测元件132c进行感测时,则通过发光元件122b进行补光。 Similarly, when the image sensing element 132c is sensed, the fill light by the light emitting element 122b.

[0005] 但是,为了使发光元件122b、122c能视情况提供正常亮度的照明光线或亮度较暗的补偿光线,需要设计复杂的驱动电路,这导致光学触控装置100成本增加。 [0005] However, in order to make the light emitting elements 122b, 122c can optionally provide normal brightness of illumination light or dark luminance compensation light, need to design complicated driving circuit, which leads to increased cost of the optical touch device 100.
