In a pixel matrix subdivided into clusters, the clusters are connected to a control circuit outside the pixel matrix (2) by way of a point-to-point connection (18). Each cluster is an active matrix structure made of row and column lines and pixel TFTs. Chains of analog (14) and digital (16) shift registers are provided for the local row and column lines. Further, clusters can be used that have a hierarchical set-up in which N local shift registers branch off of global shift registers (18). Data values are conveyed within the local shift register at a lower cycle time than the global shift register until the data values arrive at the outputs of the shift register for controlling the pixels. This control mechanism can be integrated into the pixel matrix of a display and avoids non-transparent areas.
