摘要： An optical touch module includes a display panel, an optical sensor and a light emitting unit. The optical sensor is disposed on a corner of the display panel. The light emitting unit is disposed on the optical sensor and includes a light emitting member and a compensating member. The light emitting member emits light with a first light strength along a first direction and light with a second light strength along a second direction, wherein the first light strength is greater than the second light strength. The compensating member is disposed on a side of the light emitting member. After the lights pass through the compensating member, the second light strength is increased.

摘要： An optical touch system includes a substrate, at least one sensor, a processing unit and an analysis unit. The substrate has a touch region. The at least one sensor is used for capturing a full-size image of the touch region, wherein the full-size image includes a central region image near a light axis of the at least one sensor, and a side region image. The processing unit is used for sampling the central region image to obtain a central compressed image and transmitting the central compressed image and the side region image under a normal mode. The analysis unit is used for analyzing the central compressed image and the side region image to obtain a touch point coordinate.

摘要： An optical touch system includes a first light source, a second light source, a sensing module and a processing module. The lighting timing of the second light source differs with the lighting timing of the first light source by a phase. The sensing module is for capturing a sensing image related to a touch point on a panel, and receiving a first bounce light of the touch point corresponding to the first light source and a second bounce light of the touch point corresponding to the second light source. The processing module is for obtaining angle information according to the sensing image, calculating a phase difference between the first bounce light and the second bounce light to obtain distance information, and determining a coordinate corresponding to the touch point according to the angle information and the distance information.
