    摘要: 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. Therefore, superior sight recognition of a moving image can be attained and reproduction of multi-levels gray scale in a still image can be available simultaneously.

    摘要: 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.

    摘要: 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. As a result, display quality can be reduced or prevented from deteriorating.

    摘要: A polymer dispersed liquid crystal (PDLC) display element for use in an electronic apparatus wherein the display element operates in a PDLC mode or reverse PDLC mode providing for reduction of visual display haze, improved display contrast. The particular medium includes a liquid crystal portion and a polymer portion and may include a chiral component. In cases where visual display haze and contract is a particular problem in the utility of the reverse PDLC display element, such as in the case where the display element is combined with a solar battery, a sufficient amount of dichroic dye is added to the liquid crystal portion of the medium, and, further, a compound showing no fluorescence emission with respect to a liquid crystal portion, or a polymer or a chiral polymer precursor portion of the medium, is employed. The resulting electronic apparatus can, therefore, incorporate a reverse PDLC type display element in combination with a solar battery or other component that affects display quality in such elements to improve the overall visual quality and contrast in the display rendering the display more useful in more miniaturized applications.

    摘要: A polymer dispersed liquid crystal display device includes a top substrate and a bottom substrate. First electrodes are provided on the top substrate and second electrodes are provided on the bottom substrate. Orientation are provided on the top and the bottom substrates. The orientation films are respectively rubbed in predetermined directions. A polymer material, a liquid crystal material and a predetermined amount of a chiral agent are interposed between the top and bottom substrates. The polymer material is separated from the liquid crystal material through irradiation by ultraviolet rays. The liquid crystal material and polymer material have a mutually orientated and dispersed structure. The liquid crystal material has a predetermined twisting angle in a predetermined twist direction. As a result, light is scattered when substantially normal to the liquid crystal display device and the surface of the top substrate. Thus, a polymer dispersed liquid crystal display device is obtained that is particularly bright in a specific direction.
