Active matrix display
First Claim
1. An active matrix display comprising:
- an array of picture elements comprising a first set of first picture elements and at least one second set of second picture elements;
a first refreshing arrangement for refreshing the first picture elements with arbitrary first image data supplied via data line and scan line drivers coupled to the array; and
at least one second refreshing arrangement for refreshing the second picture elements of the second set or a respective one of the second sets with constant image data which is predetermined wherein the or each second refreshing arrangement may be disabled and the second pixels of the or each second set are arranged to be refreshed by the first refreshing arrangement with arbitrary image data when the or the respective second refreshing arrangement is disabled.

Abstract
An active matrix display comprises an active matrix array of pixels divided into first and second sets, the pixels 35 of the first set are refreshed in the conventional active matrix way by a first refreshing arrangement M1, 6, 7. Pixels 36 for displaying a graphical feature such as an icon overlaid on the active matrix display image have a second refreshing arrangement M2, 6, 37 to allow the icon pixels of each icon to be switched to the same state, such as maximum back or maximum white. The icon pixels 36 may also have the first refreshing arrangement M1, 6, 7 so that they can be used either as part of the active matrix for displaying arbitrary data or when selected as such, for overlaying the icon image on the arbitrary image data.

- an array of picture elements comprising a first set of first picture elements and at least one second set of second picture elements;
-
20. A display as claimed in 17, in which the at least one second refreshing arrangement comprises means for charging data lines of the array connected to the second picture elements to a constant predefined value and the second switches are arranged selectively to connect the optical elements of the second picture elements to the data lines.
