[Prior Art] In recent years, 3C products tend to be light and thin, such as hand-held mobile phones, PDA's tablet computers, etc., and the original physical keyboard is discarded, and the pen control or finger touch control panel is used instead. The current technology can be divided into resistive, capacitive and optical touch panels, of which resistive and capacitive have been successfully applied to the product. However, since the optical touch panel is simple in structure and process, it is not easily affected by the ambient temperature and humidity, and does not need to directly conform to the original panel, does not interfere with the structure and process of the original panel, and can be applied to a large panel. So I received great attention. Most of the prior art utilizes an image capture system with a combination of circular, spherical or aspherical three-dimensional optical lenses that cannot be directly integrated with the panel, and generally cannot be reduced in thickness, limiting its range of applications. Therefore, the present invention discloses a thin and light optical sensing device to solve the above problems. [New Content] Compared with the previous technology, this creation features a two-dimensional thin wide-angle optical unit and image sensor combined into a thinner optical sensing device, and two or more opticals. The sensing device can be respectively disposed on the side or corner of the display panel or the input board to capture the dynamic touch action, and the processing unit estimates the coordinate of the touch position, the touch force track or the touch time, and completes the input action. 4r At mouth child Jr e 1 丨 之 — — 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 特色 J 丝 J 丝 J J J A piece of optical thin lens combination, which can expand the light source to the angle range of the display panel or the input board.
