A method and an apparatus for operating an LED display are provided. The method includes: storing Nth scan line data in a line buffer; storing the Nth scan line data in a frame buffer; displaying the Nth scan line data stored in the line buffer; during the displaying of the Nth scan line data stored in the line buffer, storing (N+1)th scan line data in the line buffer; storing the (N+1)th scan line data in the frame buffer; displaying the (N+1)th scan line data stored in the line buffer; repeating the above steps until (N+M)th scan line data stored in the line buffer is displayed; and displaying scan line data stored in the frame buffer from the Nth scan line data to the (N+M)th scan line data.

Light emitting diode (LED) display driver utilizing ping pong line buffer to reduce hardware costs and latency

An LED display device includes an LED array and a driver system thereof. The LED display device is configured so that LEDs in the LED array can switch between receiving scan signals at their anodes or receiving scan signals at their cathodes.

Channel-scan switchable LED driving

An LED panel has an interleaved topology in which two adjacent LED rows in the LED panel are driven by different drivers. A delay time can be implemented between starting times two adjacent LED rows. Such an LCD panel can be employed to backlight an LCD panel in an LCD display. Implementing a delay time in driving the LED panel can reduce visual artifacts in the LCD display.
