Abstract:
A plasma-addressed colour display device comprising:a layer of electro-optical material (42) sandwiched between elongated data electrodes (18) and plasma channels (20) to obtain a matrix structure of pixelelements (16), and colour filters being associated with the pixelelements (16) for obtaining groups (G) of adjacent pixelelements (16) representing different colours enabling display of a colour picture, characterized in that the display device is adapted to comprise groups (G) of pixelelements (16) each being constituted with a common data electrode (18) cooperating with a group of plasma channels (20), the colour filters being aligned with the plasma channels (20); wherein the plasma-addressed colour display device further comprises:a plasma driver circuit (28) coupled to selectively activate the plasma channels (20) in a group for selecting pixelelements (16) associated with the activated plasma channel (20), and a data driver circuit (24) receiving a video information V, and supplying colour data signals each representing one of a group of primary colours to the common data electrode (18) one by one, wherein a colour data signal being supplied to the common data electrode (18) represents the primary colour corresponding to a colour of the colour filter of the activated plasma channel (20).
