Abstract: An object of the present invention is to provide a small-sized active matrix type liquid crystal display device that may achieve large-sized display, high precision, high resolution and multi-gray scales. According to the present invention, gray scale display is performed by combining time ratio gray scale and voltage gray scale in a liquid crystal display device which performs display in OCB mode. In doing so, one frame is divided into subframes corresponding to the number of bit for the time ratio gray scale. Initialize voltage is applied onto the liquid crystal upon display of a subframe.

Abstract: A monitor provides analog conditioning circuitry for supplying a symmetrical high speed analog output signal generated from inverted and non-inverted digital data to imagers for a display of the monitor. The circuitry includes an upper bias amplifier for generating a precision upper DC offset signal. a lower bias amplifier for generating a precision lower DC offset signal, a switch for alternating selection of a precision DC offset signal with each frame, and a summing amplifier for adding the selected precision DC offset signal to a high speed analog signal provided by a digital-to-analog converter. Selection of the precision DC offset signal is controlled by an inversion signal provided to the switch from an inversion bit of a display controller. The digital data inversion is controlled by inversion circuitry within the display controller. The analog conditioning circuitry thus provides a single gain path and also provides low speed signal paths decoupled from a high speed signal path.
