Abstract: A scan-type display apparatus includes an LED array, a display module, a control module and a driver module. The LED array has a common cathode configuration. The control module generates a synchronization control (SC) signal. Based on the SC signal, the driver module outputs an input voltage to scan lines of the LED array sequentially without overlapping in time so as to drive LEDs of the LED array to emit light in a line scan manner, and generates an image refresh signal that is related to the output of the input voltage to one of the scan lines which corresponds to a last line of the line scan in each line scan cycle and that is further related to refreshing of images on a display constituted by the LED array and the display module.

Abstract: A backlight driving method is provided to include generating switching signals based on an internal synchronization control (ISC) signal related to refreshing of images on the display, a clock signal, and delay commands contained in a serial input signal that further contains an image stream. A time delay of each switching signal with respect to the ISC signal is determined by the clock signal and a respective delay command, and the time delays of the switching signals are different from one another. The method further includes generating driving signals based on the ISC signal, the clock signal and the serial input signal; and outputting the signals thus generated, to drive the backlight module to emit light in a line scan manner.

Abstract: A backlight driving method includes steps of: (A) generating an original synchronization control (SC) signal, and a serial input signal that contains multiple predetermined delay values;
(B) generating multiple internal SC signals based on the original SC signal and the delay values, such that respective time delays of the internal SC signals with respect to the original SC signal are respectively dependent on the delay values;
and (C) generating multiple backlight driving outputs based on the internal SC signals to respectively drive multiple backlight sources, such that the backlight sources emit light in an order dependent on the delay values.

Abstract: A driving device includes a control unit, a switch unit and a driver unit. The control unit is configured to generate a gray scale output and a synchronization signal. The switch unit is coupled to an LED array, and switches among different conduction states based on a switching output. The driver unit is coupled to the control unit, the switch unit and the LED array. The driver unit generates the switching output based on a clock signal and the synchronization signal, and generates drive outputs for receipt by the LED array based on the clock signal, the gray scale output and the synchronization signal, so as to drive the LED array to emit light.
