Abstract
A conformable matrix display device is provided with row conductors on the conformable carrier, each for a respective row of the matrix of pixel circuits. Each row conductor has serpentine trajectories in spaces between the pixel circuits in the respective row. Power supply voltage and selection pulse signals are transmitted over the same row conductors. Each row conductor is connected to supply voltage and selection inputs of the pixel circuits in the respective row. Each pixel circuit has a pulse transmission circuit coupled between the selection input and the control input of a de-multiplexing circuit for de-multiplexing data signals on column conductors. In this way the power supply voltage and the selection signal can be supplied making shared use of space between the pixel circuits. Thus the number of conductors in the matrix display device is reduced, which enables a greater distance between the conductors and/or bends in the conductors, which makes the circuit more stretchable and/or bendable.
