Abstract:
1. A method for driving LCD subpixels located within a first subsection of an LED backlight being driven at a first luminance and also within the tail portion of a second subsection of an LED backlight being driven at a second luminance, the method comprising the steps of: providing original subpixel voltages; providing a relative luminance versus subpixel position relationship which accepts subpixel positions and returns relative luminance values for the first and second subsections of the LED backlight; applying the relative luminance versus subpixel position relationship to the first luminance and second luminance to produce virtual backlight data for each subpixel; dividing the original subpixel voltages by a ratio of virtual backlight data to a maximum luminance to produce re-scaled subpixel voltages; and driving the subpixels with the re-scaled subpixel voltages.
