Abstract: A scan-type display apparatus includes a light emitting module, a display module, a control module and a driver module. The light emitting module includes an LED array having a common cathode configuration. The control module generates a synchronization control (SC) signal. The driver module generates a plurality of switching signals and an image refresh signal based on the SC signal. The switching signals cause the LED array to emit light in a line scan manner. The image refresh signal is related to one of the switching signals that corresponds to a last line of the line scan in each line scan cycle, and is further related to refreshing of images on a display constituted by the light emitting module and the display module.

Abstract: A method for sensing a biometric object using an electronic device includes the steps of: (a) emitting a sensing light from a backlight unit upon the biometric object contacting a sensing region on a display surface, and allowing the sensing light to pass through a color filter unit and then reach and be reflected by the biometric object to return as a reflected light; and (b) controlling arrangement of liquid crystal molecules located in a first region of a liquid crystal layer to define a first light path, and allowing the reflected light having predetermined wavelengths to pass through the color filter unit and the first light path to reach and be detected by the optical sensing unit.

Abstract: A light emitting diode (LED) failure detecting device is operatively associated with an LED array, and includes a driving circuit and a determining circuit The driving circuit drives LED units of the LED array through scan lines and data lines of the LED array in such a way that a current flows through one of the LED units. The determining circuit selects a voltage at the data line that is coupled to said one of the LED units, and generates, based on a difference between a first sample voltage that is related to at least the selected voltage at a first time point and a second sample voltage that is related to at least the selected voltage at a second time point, a determination output indicating whether said one of the LED units is determined to have failed.
