Abstract: A wearable device capable of recognizing a human face and a license plate includes a camera, an image capturing unit, a database, a central processing unit and a display unit. The camera receives external light to generate an image, and the image is captured by the image capturing unit. The captured image is transmitted to the central processing unit and recognized whether the image includes human faces or license plate of a car. The recognized data of human faces or license plate are compared with pre-stored data of human faces and license plate in the data base. When the recognized data matches the pre-stored data, the recognized data is shown in the display unit.

Abstract: In order to provide open-lamp protection to a backlight module, a pseudo open-lamp voltage is first generated according to the current flowing through a light source. If the backlight module receives a mode signal corresponding to a high contrast mode, a compensation voltage is added to the pseudo open-lamp voltage for generating a reference voltage. If the reference voltage is larger than a feedback voltage received from an input node of the light source, a driving voltage is outputted to the light source.
