PHN.11.740 13 14.7.1986 ABSTRACT Colour display device. In a colour display device colour elements (17, 18, 19, 21, 22, 23) are built up with the aid of picture cells (2) from juxtaposed rows of picture cells which are driven by line electrodes (3). The resolving power in the horizontal sense is increased by building up the colour ele- ments from picture cells of different rows of picture cells. The period t1 which is required for driving a colour element is split up into sub-periods 1/2t1 during which period samples of the signal to be displayed (length t0) are presented to the column electrodes (4). Since notably for LCD-TV there applies that t1 > t0, these samples can be presented during a period which is longer than 1/2t0.
