20100059658 | LIGHT SOURCE DETECTION DEVICE AND METHOD FOR DETECTING LIGHT SOURCE - A light source detection device includes first photo sensors disposed on a reference plane along a first direction and a control unit. Each first photo sensor has a first sensing surface for detecting a photo intensity of a light source to output a photo intensity signal. The first sensing surfaces are back to back or face to face. An included angle between a normal vector of one of the first sensing surfaces and a normal vector of the reference plane is equal to an included angle between a normal vector of another one of the first sensing surfaces and the normal vector of the reference plane. The normal vectors are coplanar. The control unit is adapted to receive the photo intensity signals and normalize the difference of the photo intensities of the light source sensed by the first photo sensors, so as to detect a position of the light source. | 03-11-2010 |
20100224758 | DISPLAY DEVICE AND LIGHT SENSING SYSTEM - A display device is applied to a light sensing system. The display device includes a display module and a pattern layer. The pattern layer is made of optical material and formatted on the display module. The pattern layer includes patterned optical material and gaps without optical material. The pattern layer selectively reflects or absorbs invisible light with specific wavelength emitted from the display module, such that a light sensor cannot sense the invisible light reflected or absorbed by the optical material or just can sense a little invisible light through the optical material. However, the invisible light can be emitted out of the gaps without the optical material, such that the light sensor can selectively sense the invisible light. Based on the light sensing result, the light sensor can recognize the corresponding pattern. | 09-09-2010 |
