Abstract:
A luminous display includes pixels arranged in rows and columns. Control signals that are used for controlling first switches for measuring parameters of pixel cells in a first row are also used to control second switches for programming pixel cells in a second row. In this way it is possible to use a single control signal for selecting one pixel cell for programming and simultaneously selecting another pixel cell for measuring. Programming and measuring are thus performed in a time staggered manner, while the addressing is moved to the respective next row. The programming is preferably voltage programming. In one embodiment the current through the pixel cell that is currently programmed is interrupted. In another embodiment the measuring is performed only after the transient current into signal holding means coupled to current control means has set.
