Dynamic update of display pixels
A system and method of driving images on displays includes receiving image content in a processing unit. When a peak data condition is identified, pixel rows of at least one display are updated in a non-sequential order in response to identifying the peak data condition.
1. A multi-panel display system comprising:
an array of pixel regions, wherein each pixel region in the array includes pixels arranged in pixel rows and pixel columns;
peak data logic coupled to receive image content and configured to analyze the image content for a peak data condition in the image content and output an enable signal in response to the peak data condition; and
scrambling circuitry coupled to receive the enable signal from the peak data logic and coupled to cause the pixel rows to be driven in a non-sequential order scan in response to receiving the enable signal, wherein the pixel rows are refreshed in a sequential raster scan when the peak data condition is not present, wherein the scrambling circuitry is coupled to transition one or more of the pixel regions between the sequential raster scan and the non-sequential order scan in response to a change of the enable signal indicating a change in the peak data condition.
2. The multi-panel display system of claim 1 , wherein the peak data logic is included in a display panel that includes at least one of the pixel regions.
3. The multi-panel display system of claim 1 , further comprising a processing unit coupled to drive multiple display panels arranged as a multi-panel display, wherein the peak data logic is included in the processing unit and the processing unit is external to the display panels.
4. A multi-panel display system comprising:
an array of pixel regions, wherein each pixel region in the array includes pixels arranged in pixel rows and pixel columns;
peak data logic coupled to receive image content and configured to analyze the image content for a peak data condition in the image content and output an enable signal in response to the peak data condition;
scrambling circuitry coupled to receive the enable signal from the peak data logic and coupled to cause the pixel rows to be driven in a non-sequential order scan in response to receiving the enable signal, wherein the pixel rows are refreshed in a sequential raster scan when the peak data condition is not present;
timing and controller processing logic coupled to receive the image content; and
pixel driving circuitry coupled to drive the pixel regions, wherein the scrambling circuitry is coupled between the timing and controller processing logic and the pixel driving circuitry.
