OPTICAL IMAGING SYSTEM CAPABLE OF PREVENTING OVEREXPOSURE

摘要

An optical imaging system capable of preventing overexposure includes a display panel, at least one light source, at least one reflective unit, at least one image capturing module and a control module. The at least one image capturing module is disposed on an outer side of the display panel and is spaced from the at least one reflective unit in a predetermined distance. The at least one reflective unit reflects light reflected from a touch object to the at least one image capturing module, and the at least one image capturing module captures the light reflected from the touch object to generate a corresponding touch signal. The control module is coupled to the at least one image capturing module and for calculating a coordinate value of the touch object on a coordinate detecting area of the display panel according to the touch signal.

1. An optical imaging system capable of preventing overexposure, and the optical imaging system comprising:
a display panel, whereon a coordinate detecting area is formed; at least one light source module disposed on an outer side of the display panel and for emitting light so as to illuminate an touch object within the coordinate detecting area; at least one reflective unit disposed on an outside corner of the display panel; at least one image capturing module disposed on an outer side of the display panel and being spaced from the at least one reflective unit in a predetermined distance, the at least one reflective unit reflecting light reflected from the touch object to the at least one image capturing module, the at least one image capturing module capturing the light reflected from the at least reflective unit so as to generate a touch signal corresponding to the touch object; and a control module coupled to the at least one image capturing module and for calculating a coordinate value of the touch object on the coordinate detecting area of the display panel according to the touch signal.
