Abstract: An information handling system display backlight illuminates an image with plural strings of LEDs driven by a backlight driver integrated circuit with pulse width modulation. A string detection module detects the number of active LED strings and divides the time period by number of active LED strings into an equal number of time delays or shifts so that the backlight driver sequentially turns on an LED string at a predetermined time period. The active number of LED strings is detected by reading a total number of LED strings from a management interface and subtracting from the total number any detected failed LED strings or any LED strings powered down to reduce power consumption.

Abstract: In accordance with embodiments of the present disclosure, an information handling system is provided. The information handling system may include a processor; a display coupled to the processor, the display comprising a pixel clock source configured to generate a pixel clock frequency; a memory device coupled to the processor, the memory device having a lookup table stored thereon; and a controller coupled to the processor and configured for: receiving frequency information associated with wireless transmissions of the information handling system; and dynamically adjusting the pixel clock frequency by selecting a frequency from the lookup table in response to a determination that the received frequency information is approximately equal to the pixel clock frequency.

Abstract: A Red, Green, Blue Light Emitting Device (RGB LED) backlight color control system includes an RGB LED backlight comprising a red LED, a green LED, and a blue LED. A driving current regulator is coupled to each of the red LED, the green LED, and the blue LED. A backlight power control is coupled to each of the driving current regulators and operable to receive adjustment data and use the adjustment data to adjust the driving current supplied by at least one of the driving current regulators to at least one of the red LED, the green LED, and the blue LED. By adjusting the driving current supplied to the red LED, green LED, and/or the blue LED, color pallet points on a color triangle (associated with a display that uses the RGB LED backlight) are shifted to achieve the color desired by the user, avoiding the loss of color pallet points in the color triangle that occurs with conventional re-mapping techniques.
