Abstract:
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.
