摘要： A backlight dimming method for backlighting an LCD panel having a variable refresh rate with an LED module, the variable refresh rate having a maximum refresh rate, the LED module having at least one LED sub-zone, the LED sub-zone including a plurality of LEDs, and the method including: using a controller to generate a secondary synchronizing signal having a frequency higher than the maximum refresh rate; and using the controller to update dimming values for the at least one LED sub-zone at one or more pulses of the secondary synchronizing signal with current dimming data after the controller has received the current dimming data from a scaler.

摘要： A control system for a light emitting device includes N number of drive circuits that are connected in series, N number of transmission lines, a common transmission line, a control line electrically connected to the N number of transmission lines and the common transmission line, and a control circuit electrically connected to the control line for outputting a command signal, where N≥2. The command signal is configured for address setting, brightness control or data fetch. The N number of transmission lines are electrically connected to the N number of drive circuits, respectively. Each of the N number of drive circuits has a state setting operable to switch between a transmission state and a non-transmission state. When the state setting of every single one of the N number of drive circuits is in the transmission state, the N number of drive circuits form a pass-through signal transmission path.

摘要： A control system for a light emitting device is provided. The control system includes a control circuit, a common transmission line and a drive circuit string. The control circuit includes a control terminal. The drive circuit string includes N number of drive circuits, where N≥2. The drive circuit string is electrically connected to the control terminal of the control circuit through the common transmission line. Each of the drive circuits has a state setting. The state setting is in a transmission state when a setting of an assigned address of the drive circuit is completed. The control terminal transmits a command signal to each of the drive circuits via the common transmission line. The drive circuits read a command data piece or command data pieces within the command signal based on the assigned address.
