Abstract
A low power standby driving mode is obtained by using extra columns (14) (or rows) by which only a small area of the display is driven. For standby driving, a separate driver (11) is used at the edge of the panel, or this driver is combined with the normal driver. In another embodiment, the standby driving mode is obtained by splitting columns (6) (or rows (5)) so that only a defined area (12) of the display is driven during standby driving. For normal driving, an additional row (16) and switches (17) may be used to interconnect separate parts of a split electrode via switches.
Claims9
A display device (1) comprising, on a substrate, a matrix of selection electrodes (5) and data electrodes (6) with a pixel (8) at the area of a crossing of the selection electrodes and data electrodes, and at least one switching element and drive means (3, 9, 10, 11) for driving the selection electrodes and data electrodes, characterized in that the display device comprises means for reducing the capacitance for a part of the group of selection electrodes (5) or the group of data electrodes (6) with respect to that of further selection electrodes (5) or data electrodes (6).
A display device (1) comprising, on a substrate, a matrix of selection electrodes (5) and data electrodes (6) with a pixel at the area of a crossing of the selection electrodes and data electrodes, and at least one switching element and drive means for driving the selection electrodes and data electrodes, characterized in that the display device comprises means (16, 17) for temporarily reducing the capacitance for at least a part of the group of selection electrodes (5) or the group of data electrodes (6).
