摘要： An LED control circuit comprises a driver, a counter, and a controller and is configured to control a plurality of light-emitting units, each of which comprises at least one LED and a switch. The driver receives an alternating-current signal to output a driving signal whereby the light-emitting units are enabled. The counter begins a count from a start number when a voltage value of the driving signal equals a base value. When the count reaches a predetermined number, the controller controls the switch of at least one of the light-emitting units, causing the LED of the light-emitting unit to receive the driving signal. When the LED of the light-emitting unit receives the driving signal, the controller detects whether the light-emitting unit is enabled and adjusts the predetermined number accordingly.

摘要： The present disclosure relates to a display apparatus and a method for monitoring the same. A display apparatus is provided. The display apparatus comprises a display unit, a backlight module, a light sensor, and a controller. The backlight module is located on a first side of the display unit. The light sensor is located on a second side of the display unit different from the first side. The light sensor faces away from the display unit for detecting light comprising ambient light and reflected light from the display unit and generates a first brightness value. The controller determines the display apparatus malfunction based on the first brightness value.

摘要： A method for sending commands to display devices connected in series includes sending a command to the first display device of N display devices connected in series. The command has a header and each of the N display devices has a same preset identification code. The first display device of N display devices receives the command and determines whether the header is corresponding to the preset identification code. When the header of the command is corresponding to the preset identification code, the first display device executes the command. When header of the command is different from the preset identification code, the first display device generates a modified command by adding an adjustment to the header of the command and sends the modified command to the next display device.

摘要： A display system with fan control which includes a display module, a fan, a temperature detector and a fan controller is provided. The fan is configured to generate an air flow in the display system. The temperature detector is configured to detect temperature within the display system. The fan controller is configured to generate a control signal to control a rotational speed of the fan based on the detected temperature and a first time period since the detected temperature reaches a first threshold and in which the detected temperature remains equal to or higher than the first threshold. The fan controller remains the rotational speed of the fan unchanged when the detected temperature is lower than the first threshold.
