Abstract: An exemplary light sensor (20) includes a supporting base, a light-sensing unit (21) provided at at least one first location of the supporting base where ambient light is received, and a compensating unit (22) provided at a second location of the supporting base shielded from ambient light, the compensating unit having a structure that is the same as the light-sensing portion. The light-sensing portion includes at least one amorphous silicon thin film transistor (TFT) (210) configured for sensing light, and the compensating unit is configured for providing a reference value current for the light-sensing unit. A display device using the light sensor is also provided.

Abstract: A universal serial bus connector includes a main body and at least one indicator. The main body is formed from an insulator material, and has a plug inserting side and a board mounting side. The plug inserting side is formed with at least one plug slot that has a set of conductive contact terminals mounted therein. The contact terminals have solder tails that extend through the board mounting side. The indicator is mounted on the main body, and has power terminals separate from the contact terminals. When the contact terminals and the power terminals are mounted on a circuit board, the indicator can be controlled via the power terminals to indicate the status of signal transmission through the contact terminals.
