Abstract: A scan-type display apparatus includes an LED array and a data driver. The LED array has a common anode configuration, and includes multiple scan lines, multiple data lines and multiple LEDs. The data driver includes multiple data driving circuits, each of which includes a current driver and a detector. The current driver has an output terminal connected to the data line corresponding to the data driving circuit, and outputs one of a drive current and a clamp voltage at the output terminal of the current driver based on a pulse width control signal. The detector is connected to the current driver, and generates a detection signal that indicates whether any one of the LEDs connected to the data line corresponding to the data driving circuit is short circuited based on a detection timing signal and a feed-in voltage related to a voltage at the output terminal of the current driver.

Abstract: A scan-type display apparatus includes an LED array and a scan driver. The LED array has a common anode configuration, and includes multiple scan lines, multiple data lines and multiple LEDs. The scan driver includes multiple scan driving circuits. Each scan driving circuit includes a voltage generator and a detector. The voltage generator has an output terminal that is connected to the scan line corresponding to the scan driving circuit, and is configured to output one of an input voltage and a clamp voltage at the output terminal of the voltage generator. The detector is connected to the output terminal of the voltage generator, and generates a detection signal that indicates whether any one of the LEDs connected to the scan line corresponding to the scan driving circuit is short circuited based on a voltage at the output terminal of the voltage generator and a detection timing signal.

Abstract: A webcam apparatus and a monitoring system are provided. The webcam apparatus includes a camera, a processor, and a first communication module. The camera is configured to obtain a video screen. The processor is coupled to the camera. The processor analyzes the video screen. The first communication module is coupled to the processor. When the first communication module communicates with an electronic device, the first communication module outputs the video screen to the electronic device. When the processor determines that a moving object moves to a specific screen block in the video screen, the processor outputs a warning signal.
