    • A laser beam recording method and apparatus are constituted for recording a continuous tone image by scanning a laser beam emitted by a semiconductor laser on a photosensitive material by a beam scanning system, and controlling a drive current for the semiconductor laser based on a light emission level instructing signal corresponding to an image signal, thereby to modulate the intensity of the laser beam. The laser beam intensity is detected, and a feedback signal corresponding to the detected intensity is fed back to the light emission level instructing signal. The light emission level instructing signal is corrected by a correction table to compensate for nonlinearity of drive current-optical output characteristics of the semiconductor laser and/or nonlinearity of incident light intensity-optical transmittance characteristics of an optical element of the beam scanning system, thereby to make linear the relationship between the intensity of the laser beam based on the corrected light emission level instructing signal and the uncorrected light emission level instructing signal.
    • 一种激光束记录方法和装置,用于通过用光束扫描系统扫描由半导体激光器发射的激光束在感光材料上记录连续色调图像,并且基于发光水平控制半导体激光器的驱动电流 指示对应于图像信号的信号,从而调制激光束的强度。 检测激光束强度,将与检测出的强度对应的反馈信号反馈给发光电平指示信号。 通过校正表校正发光电平指示信号,以补偿半导体激光器的驱动电流 - 光输出特性的非线性和/或光束扫描系统的光学元件的入射光强度 - 光透射特性的非线性,从而 基于校正的发光电平指示信号和未校正的发光电平指示信号来使激光束的强度之间的关系成线性。

    • In the case where one horizontal period becomes shorter as a high frame rate drive of 120 Hz or higher is introduced or the resolution is increased, the time for the writing in of a voltage to the holding capacitor of pixels cannot be sufficiently secured.Two data lines are provided to an electrode for supplying a data voltage to a group of pixels in the vertical direction in such a manner that one data line of the two data lines is connected to one of the two pixels in the vertical direction and the other data line of the two data lines is connected to the other pixel, while one gate line shared by two horizontal lines formed of two pixels, to which different data lines adjacent in the vertical direction are connected, is provided and connected to the electrode for controlling the turning ON/OFF, the data line driving portion has outputs of which the number is two times greater than the number of horizontal pixels in order to make it possible to apply a voltage simultaneously to the pixels for two horizontal lines, and the gate line driving portion has outputs of which the number if ½ the number of vertical pixels by connecting one gate line to two horizontal lines.
    • 在引入120Hz以上的高帧率驱动或分辨率增加的情况下,一个水平周期变短,不能充分确保向像素的保持电容器写入电压的时间。 两个数据线被提供给电极,用于以垂直方向的一组像素提供数据电压,使得两条数据线的一条数据线连接到垂直方向上的两个像素之一,另一条数据线连接 两条数据线的数据线连接到另一个像素,而由垂直方向相邻的不同数据线连接的两个像素构成的两条水平线所共用的一条栅极线被连接到用于控制的电极 打开/关闭时,数据线驱动部分具有数字是水平像素数量的两倍的输出,以便能够同时向两条水平线的像素施加电压,并且栅极线 驱动部分具有通过将一个栅极线连接到两条水平线的数量,如果是垂直像素数量的1/2的输出。
