Abstract: A method of sub-field drive can display with a mode of placing emphasis on responsiveness and display with a mode of placing emphasis on gray-scale reproductiveness. A field is divided into plural sub-fields on a time axis, and each of such sub-fields is a control unit of driving a pixel. A code storing ROM stores a code that controls sub-fields to collecting on-voltage intensively in a former part of a field based on display data. Another code storing ROM stores a code that controls sub-fields to increase levels of gray scale based on display data. A data encoder determines whether each pixel of display data is an edge part of a moving image or not, selects a code that enables superior display in responsiveness at the edge part of a moving and selects a code that enables superior display in gray scale reproductiveness in other parts from the ROMs.

Abstract: A coordinate input device is associated with a liquid crystal display to detect a touch or contact thereon. A transparent board is arranged on the screen of the display to provide a coordinate input surface having a substantially rectangular shape. At least one vibration detector (e.g., a microphone or piezoelectric element) is attached onto the board to detect vibration or sound that occurs when a position input member is brought into contact with the coordinate input surface at an arbitrary input position. The input position is represented as one-dimensional coordinate based on outputs of two vibration detectors, or it is represented as two-dimensional coordinates based on outputs of three vibration detectors. Thus, the manually designated input position is detected and is electronically displayed on the screen of the display. As the position input member, it is possible to use a pen, a fingernail, etc.

Abstract: The invention provides a system and methods for driving an electrooptic device where one field is divided into a plurality of subfields on a time base, thereby to set the subfields as control units for driving a pixel. A liquid crystal that exhibits such a low response rate that the saturation response time thereof is longer than one subfield period. Accordingly, even when an ON voltage is applied to the liquid crystal in only one predetermined subfield by way of example, the transmission factor of the liquid crystal does not reach 100%. That is, the change of the transmission factor in each subfield can be finely controlled in the transitional period of the transmission factor of the liquid crystal. Accordingly, the number of gradations can be remarkably enlarged as compared with the number of the subfields within one field, and displays at multiple gradations can be accomplished.

Abstract: A display provided to reduce flicker by a driving method of using a sub field drive. One field is divided into plural sub fields on a time axis, each of which is a control unit to drive a pixel. A code storing ROM stores a code to give a sub field drive pattern based on display data. With respect to adjacent pixels within a control area, a data encoder writes pixel data by using a sub field drive pattern read from the code storing ROM and a pattern delayed by the predetermined sub field period. Hence, adjacent pixels are driven by different sub fields drive patterns each other so that timing of flickering among adjacent pixels is differentiated.

Abstract: Exemplary embodiments of the present invention provide an image rearranging unit that synthesizes an input image with a delayed signal thereof and arranges an image having a horizontal frequency n times larger than a horizontal frequency of the input image in a signal arrangement according to scanning of a scanning driver, to thereby obtain a write image. The scanning driver selects n scanning lines spaced apart from each other in one horizontal period of the input image and drives pixels with image signals having the same polarity between most adjacent lines. Thus, a horizontal electric field can be reduced or prevented by a plane inversion driving. Adjacent to a blanking period having a polarity, a write operation by an image signal having an opposite polarity is performed. In this case, however, a low level blanking signal, for example, is also used, instead of a blanking signal. Thus, in the blanking period, the write operation of the image signal is not affected by a high black level ghost.
