Abstract

A two-dimensional panel, particularly a liquid crystal display device, has a maximum display area with a width of (T×M) addressable channels. The addressable channels are addressed through a plurality of T source channel integrated circuits (ICs), with each source channel IC having M source channels. The number of addressable channels exceeds the number of channels of data in an image display data array having a width of W pixels, each pixel comprising P subpixels in the width dimension. The excess addressable channels are distributed symmetrically across the width dimension of the displayed image. In other embodiments the number of addressable channels is less than the number of channels of data and excess channels of data are excluded symmetrically across the width dimension of the displayed image. Further embodiments distribute excess addressable channels symmetrically across the height dimension or exclude excess channels of data symmetrically across the height dimension.
