Thermal management of display screens
First Claim
1. A computer-implemented method comprising:
- dividing a video frame into two or more frame regions, wherein;
each of said two or more frame regions correspond to a selectively coolable region of a display;
said selectively coolable region of said display includes a plurality of light emitting diodes; and
a plurality of microfluidic circuits surround said plurality of light emitting diodes;
determining, for each of said two or more frame regions, a heat value based, at least in part, on said one or more frame characteristics for each of said two or more frame regions, wherein said heat value is an estimation of an electrical input power of said plurality of light emitting diodes included in said selectively coolable region of said display at a time said video frame is displayed;
determining a cooling intensity to be applied to each said selectively coolable region of said display based, at least in part, on said heat value; and
proactively altering a volume and a flow rate of a coolant through said plurality of microfluidic circuits included in each said selectively coolable region based, at least in part, on said cooling intensity for each said selectively coolable region at an effective time prior to an appearance of said video frame on said display.

Abstract
A computer-implemented method includes receiving a video frame. The computer-implemented method further includes dividing the video frame into two or more frame regions, each of the two or more frame regions corresponding to a selectively coolable region of a display. The computer-implemented method further includes identifying one or more frame characteristics for each of the two or more frame regions. The computer-implemented method further includes determining a cooling intensity to be applied to each selectively coolable region for displaying the video frame on the display based on the one or more frame characteristics. The computer-implemented method further includes applying the cooling intensity to each selectively coolable region at an effective time before displaying the video frame on the display. A corresponding computer system and computer program product are also disclosed.
