Patent ID: 8179336

Claim:
A tiled display having an emissive image area that causes light emission, comprising: a. a plurality of display tiles aligned so that they provide the emissive image area; each display tile including: i. a plurality of light-emitting pixels arranged in groups of pixels in the emissive image area; ii. a plurality of sequentially arranged pixel drive circuits and each pixel drive circuit being electrically connected to a particular group of pixels for controlling the light emission of such pixels; iii. a data source that is separate from the display tiles and configured to receive image information and to produce data, the data source including a plurality of parallel signal communication line(s) that provide the data for controlling the operation of each pixel drive circuit and one or more first in-series signal communication lines so as to provide information to the first one of the sequentially arranged pixel drive circuits; and iv. each pixel drive circuit being configured to: receive, via the plurality of parallel communication lines, a portion of the data from the data source so as to control the light emission of its corresponding group of pixels, provide, via one or more second in-series communication lines, information to the next sequential pixel drive circuit to cause such next sequential pixel drive circuit to respond to its corresponding data to control the operation of its group of light-emitting pixels, and repeat this operation until a predetermined number of pixel drive circuits have caused the desired light emission from the emissive area, wherein each display tile includes first edges which are parallel to each other and a second edge perpendicular to the first edges, wherein the sequence of pixel drive circuits of each display tiles is aligned along the first edges, wherein the plurality of parallel signal communication lines and the one or more first in-series communication lines are connected through the second edge to the data source, and wherein each display tile includes its own substrate.
