First Claim
Patent Images
1. A panel controller for use with a display panel, the panel controller comprising:
- interface logic for connecting the panel controller to the display panel;
a pixel engine coupled to the interface logic for generating output pixel data to be sent to the display panel; and
an output configurator coupled to the interface logic and the pixel engine, to configure at least one operating characteristic of the pixel engine in response to at least one parameter received from the display panel.

Abstract
A panel controller is brought closer to the graphics controller and other components of the video subsystem. The panel controller is reconfigurable, such as by parameters received from the display panel, and is thus useable with multiple different species of display panel.
