    • A liquid crystal display apparatus includes an LCD having a plurality (N) of row electrodes and a plurality (M) of column electrodes which intersect to each other orthogonally. A plurality (n) of row electrodes of the plurality (N) of row electrodes are individually and simultaneously driven by a plurality (n) of row drivers with voltages which are determined according to Walsh functions. A VGA controller which receives a video signal outputs display data of one frame. A plurality (n) of storages individually store the display data of each of n rows which are simultaneously driven. The display data from respective storages are applied to a plurality (m) of calculation circuits. Respective calculation circuits calculate driving voltage values for respective column electrodes in accordance with the Walsh function and the display data so as to apply the same to a plurality (m) of column drivers, respectively. Respective column drivers drive the column electrodes included in each of a plurality (m) column electrode groups with the driving voltage values.
    • 液晶显示装置包括具有多个(N)行电极和多个垂直于彼此相交的(M)列电极的LCD。 多个(N)行电极中的多个(n)行电极由具有根据沃尔什函数确定的电压的多个(n)行驱动器单独并且同时驱动。 接收视频信号的VGA控制器输出一帧的显示数据。 多个(n)个存储器分别存储同时驱动的n行中的每一个的显示数据。 来自各个存储器的显示数据被应用于多个(m)个计算电路。 相应的计算电路根据沃尔什函数和显示数据分别计算各列电极的驱动电压值,以分别将它们应用于多个列驱动器。 各列驱动器驱动包括在多个(m)列电极组中的每一个中的列电极与驱动电压值。

    • A liquid crystal display (LCD) 1 according to an embodiment of the present invention includes a liquid crystal panel having a TFT substrate 2, a CF substrate 25, and a liquid crystal layer 14 interposed between the two substrates; a TFT ambient light photosensor having a semiconductor layer 19L for detecting external light; a photodetector unit LS1 having a capacitor Cw in which a predetermined reference voltage is charged and a voltage charged by leakage current of the TFT ambient light photosensor is lowered; and an ambient light photosensor reader unit Re1 for reading a voltage charged in the capacitor for a predetermined read period. The photodetector unit is disposed on a first surface of the TFT substrate 2 that is in contact with the liquid crystal layer, and the surface of the photodetector unit except for the semiconductor layer 19L and its periphery is covered by a light-shielding layer 21. It is therefore possible to provide an LCD in which malfunction or reduced sensitivity of its ambient light photosensor due to light from its backlights is prevented with a simple structure.
    • 根据本发明实施例的液晶显示器(LCD)1包括具有TFT基板2,CF基板25和插入在两个基板之间的液晶层14的液晶面板; 具有用于检测外部光的半导体层19L的TFT环境光传感器; 具有预定参考电压被充电的电容器Cw和TFT环境光电传感器的漏电流充电的电压的光检测器单元LS1降低; 以及环境光光传感器读取器单元Re1,用于读取在预定读取周期内在电容器中充电的电压。 光检测器单元设置在与液晶层接触的TFT基板2的第一表面上,除了半导体层19L及其周边之外的光检测器单元的表面被遮光层21覆盖。 因此,可以提供一种LCD,其中以简单的结构防止由于其背光的光而导致的环境光传感器的故障或降低的灵敏度。
