Abstract
Disclosed is a display device for use of a surface display of an arbitrary shape, including a plural number of display element units, each made up of a circuit that forms a single stage of a scanning circuit and a pixel circuit connected to an output of the scanning circuit, are arranged in a unicursal fashion on a display substrate.
Claims5
A TFT display device comprising:
- a plurality of stages of unit circuits arranged in a cascade connection to form a scanning circuit,
- each of the unit circuits including an input node to receive a scanning signal and an output node to output the scanning signal, each of the unit circuits, responsive to a clock signal, transferring the scanning signal received at the input signal thereof to a succeeding unit circuit from the output node thereof and supplying the scanning signal from the output node thereof to a pixel circuit arranged in a stage corresponding to each of the unit circuits, the unit circuit arranged in a first stage receiving the scanning signal supplied from an scanning signal input terminal of the device and remaining unit circuits each receiving the scanning signal output from the output node of a preceding unit circuit;
- and
- a plurality of the pixel circuits, each of the pixel circuits including:
- a display element;
- and
- a pixel switch transistor adapted to be turned on and off by the scanning signal supplied thereto from the output node of a corresponding unit circuit, the pixel switch transistor arranged between a terminal to which a data signal is supplied and one end of the display element,
- each of the unit circuits and each of the pixel circuits corresponding to each of the unit circuit constituting one display device element,
- wherein a plurality of the display device elements are arranged in one stroke to form a display area having a plurality of the display elements arranged in two dimensional directions, and
- wherein each of the unit circuits includes a switch controlled by the clock signal to be turned on and off, the switch, when turned on, transferring the scanning signal.
