Abstract: A metal-oxide semiconductor module includes multiple metal-oxide semiconductor components separated from one another by at least one first trench. Each of the metal-oxide semiconductor components includes a heavily doped semiconductor layer which includes a drain region, an epitaxial layer which is formed with an indentation such that the drain region is partially exposed from the epitaxial layer, and a metallic patterned contact unit. The epitaxial layer also includes a source region and a gate region that are spaced-apart formed therein. The metallic patterned contact unit includes source, gate, and drain patterned contacts which are electrically connected to the source, gate, and drain regions, respectively. A light-emitting diode display device including the metal-oxide semiconductor module is also disclosed.

Abstract: A method of building a model of defect inspection for a light-emitting diode (LED) display is adapted to be implemented by a model-building system. The model-building system stores captured images respectively of LED displays that were displaying images. Each of the captured images corresponds to a status tag that indicates a status of the image being displayed by the respective one of the LED displays. The method includes: performing data preprocessing on the captured images to result in pieces of pre-processed data that respectively correspond to the captured images; and building a model of defect inspection by using an algorithm of machine learning based on the pieces of pre-processed data and the status tags.

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 display device includes a substrate, a drive power circuit, a gate circuit unit, multiple LEDs and a power switch unit. The power switch unit includes multiple first transistor switches and at least one second transistor switch that cooperatively control current flows through the LEDs. The first transistor switches are respectively connected to first terminals of the LEDs. The at least one second transistor switch is connected to second terminals of the LEDs. The first transistor switches are further connected to the drive power circuit to receive multiple drive currents, and are further connected to the gate circuit unit to receive a timing input. The at least one second transistor switch is further connected to the gate circuit unit to receive a timing input. The light emitting display device can have reduced parasitic capacitance effect, and thus reduced power consumption and have improved display quality.
