A plurality of variable biasing devices (13, 15, 17) for controlling the deselect modes of operation of each stage (22, 24, 26) of the liquid crystal display panel assembly (11) to optimize substantially the contrast between each individual deselect state and corresponding select states. The devices include an isolation device (68) to enable the contrast between the select and deselect modes to be made, independently of the intensity adjustments for the select modes of operation. |
