MULTIPLE DISPLAY SYNCHRONIZATION

Abstract:

A device (100) includes a plurality of display panels (102), a plurality of display controllers (116), each display controller of the plurality of display controllers being configured to control a corresponding display panel of the plurality of display panels, each respective display controller of the plurality of display controllers being configured to generate a timing indication (134), and a processor (136) coupled to the plurality of display controllers to receive the timing indications from the plurality of display controllers. Each timing indication is indicative of the respective display controller residing in a state ready for refresh of the corresponding display panel. The processor is configured to delay a refresh of the plurality of display panels until the timing indication is received from each respective display controller of the plurality of display controllers to synchronize the plurality of display panels.
