[0068] figure 2 It is a schematic diagram of a touch module (touch module) according to the first embodiment of the present invention, wherein figure 2 The top of is the cross-sectional view of the touch module, while figure 2 Below is the top view of the touch module. Please refer to figure 2The touch module 200 of this embodiment includes a light guide plate 210 , an optical glue 220 , a touch sensing module 230 and a retro-reflector 240 . The light guide plate 210 has an end surface S2 and a plurality of optical surfaces S3. The touch sensing module 230 is disposed on the end surface S2 , and the touch sensing module 230 includes a sensing component 232 and a light source 234 . In addition, the light guide plate 210 further has a top surface S9, and the end surface S2 and the optical surface S3 are substantially perpendicular to the top surface S9. Additionally, if figure 2 As shown below, the end surface S2 is an inclined plane. In detail, the end surface S2 of...

[0077] Figure 5 It is a schematic diagram of a touch module according to the second embodiment of the present invention, wherein Figure 5 The top of is the cross-sectional view of the touch module, while Figure 5 Below is the top view of the touch module. Please refer to Figure 5 , the touch module 400 of this embodiment and figure 2 The touch module 200 is similar, but the main difference between the two is: the touch module 400 does not use figure 2 Instead, the light source 234' is directly disposed on the optical surface S3, wherein the light source 234' is a plurality of light bars.

[0078] Such as Figure 5 As shown, the light source 234' is adapted to provide light L2 into the light guide plate 210, and the sensing element 232' is adapted to receive the light L2 transmitted through the light guide plate 210. When the user touches the light guide plate 210 with a finger F or a stylus, the light L2 near the touch point P will be scattered, and the above-menti...

Description

【Technical field】 [0001] The present invention relates to a touch module and a sensing device, and in particular to an optical touch module and a sensing device. 【Background technique】 [0002] According to different sensing methods, touch panels can be roughly divided into resistive touch panels, capacitive touch panels, optical touch panels, acoustic touch panels, and electromagnetic touch panels. Since the touch mechanism of the optical touch panel is suitable for large-size display panels, the touch function of the large-size display panel is mostly achieved through the optical touch mechanism. [0003] Most of the current optical touch display panels use infrared light as a light source, and use a complementary metal oxide semiconductor photosensor (CMOS optical sensor) to sense the infrared light. For example, manufacturers have integrated infrared light-emitting diodes (IR-LEDs) capable of emitting infrared light and complementary metal oxide semiconductor photosenso...
