    • A liquid crystal display is constructed so that the representative gray scale levels are extracted and set at close intervals in the gray scale transition areas where the optical response characteristics of the LCD panel are poor while the representative gray scale levels are set at dispersed intervals in the gray scale transition area where the optical response characteristics of the LCD panel is relatively good, to thereby allot the selected representative gray scale levels to the addresses of the OS table. A write gray scale determining portion, referring to compensation signal data values stored in correspondence with the combinations of the respective representative gray scale levels, determines the write gray scale data to the LCD panel, whereby the optical response characteristics of the LCD panel can be compensated with high precision.
    • 液晶显示器被构造成使得代表性的灰度级别被提取并且在灰度级过渡区域中以紧密的间隔设置,其中LCD面板的光学响应特性差,而代表性灰度级别以分散间隔设置在 灰度级过渡区域,其中LCD面板的光学响应特性相对较好,从而将所选择的代表性灰度级别分配给OS表的地址。 写入灰度级确定部分,参考与各代表性灰度级别的组合相对应存储的补偿信号数据值,将写入的灰度数据确定到LCD面板,由此可以补偿LCD面板的光学响应特性 精度高。

    • A light modulating device, such as a ferroelectric liquid crystal display (FLCD) comprises an addressable matrix and modulating elements or pixels and associated circuitry for selectively addressing each element in a series of addressing frames in order to vary the transmission level of each element relative to the transmissions levels of the other elements. Such addressing utilises a temporal dither addressing scheme for addressing at least part of each element within each frame with different combinations of temporal dither signals applied to separately addressable temporal bits within the frame to produce different transmission levels. In order to enable a large number of grey levels to be produced whilst limiting the perceived errors at transitions between different grey levels, the temporal bits are addressed in a first order in a first frame (or in a first spatial location) and in a second order, which is different to the first order, in a second frame (or in a second spatial location). The order in which the temporal bits are addressed may be varied according to a prescribed sequence, for example alternating between successive frames, along each line or between corresponding frames on adjacent lines.
    • 诸如铁电液晶显示器(FLCD)的光调制装置包括可寻址矩阵和调制元件或像素和相关联的电路,用于选择性地寻址一系列寻址帧中的每个元件,以便改变每个元件相对于 其他元素的传输级别。 这样的寻址使用时间抖动寻址方案,用于将时域抖动信号的不同组合施加到帧内的可分别寻址的时间位以产生不同的传输电平来寻址每个帧内的每个元件的至少一部分。 为了能够在限制不同灰度级之间的转换处的感知误差的同时产生大量的灰度级,在第一帧(或在第一空间位置)和第二帧 在第二帧(或第二空间位置)中与第一顺序不同的顺序。 时间位被寻址的顺序可以根据规定的顺序而变化,例如在连续的帧之间沿着每条线或在相邻行上的相应帧之间交替。

    • The device includes: a write-gray scale level determining means (2), (3) for determining the write-gray scale level data for input image data that compensates the optical response characteristic of a liquid crystal display panel (4), in accordance with, at least, the combination of the gray scale level transitions from a previous vertical period to a current vertical display period; and an achievable gray scale level determining means (5), (6) for generating the achievable gray scale level data for input image data after a lapse of one vertical display period of the liquid crystal display panel, in accordance with, at least, the combination of the gray scale level transitions from one vertical display period to the next. The write-gray scale level determining means (2), (3) determines the write-gray scale level data to be supplied to the liquid crystal display panel (4), based on the achievable gray scale level data of the liquid crystal display panel (4), corresponding to the input image data at the previous vertical display period, output from the achievable gray scale level determining means (5), (6) and the input image data at the current vertical display period. In this way, it is possible to correctly inhibit generation of afterimages and present correct display of half gray scales even for motion pictures containing any kind of gray scale level transition, by implementing overshoot drive of the liquid crystal display panel using actual achievable gray scale levels within the one vertical display period, even if any type of gray scale level transition occurs from one vertical display period to the next.
    • 该装置包括:写入 - 灰度级确定装置(2),(3),用于根据对应于液晶显示面板(4)的光学响应特性的输入图像数据确定写入 - 灰度级数据 至少具有从先前垂直周期到当前垂直显示周期的灰度级转换的组合; 以及可实现的灰度级判定装置(5),(6),用于在至少液晶显示面板的一个垂直显示周期经过了一个垂直显示周期之后,生成用于输入图像数据的可达到的灰度级数据 从一个垂直显示周期到下一个垂直显示周期的灰度级转换的组合。 写入 - 灰度级确定装置(2),(3)基于液晶显示面板(4)的可实现的灰度级数据确定要提供给液晶显示面板(4)的写灰度级数据 (4),对应于在先前垂直显示周期的输入图像数据,从可实现的灰度级确定装置(5),(6)输出的输入图像数据和当前垂直显示周期的输入图像数据。 以这种方式,通过使用实际可实现的灰度级来实现液晶显示面板的超调驱动,可以正确地抑制残影的产生,并且即使对于包含任何种类的灰度级转换的运动图像也能正确显示半灰度级 在一个垂直显示周期内,即使从一个垂直显示周期到下一个垂直显示周期发生任何类型的灰度级别转换。
