    • PURPOSE: An LCD panel driver for reducing cross-talk is provided to improve a contrast of an LCD panel by preventing cross-talk. CONSTITUTION: An LCD driver(20) receives processed information from a host(10) such as a system unit of a personal computer. The LCD driver(20) is composed of a voltage divider(22), an LCD controller(24), a row driver(26) and a column driver(28). The voltage divider(22) generates one group of divided voltages(V0,V1,V4,V5) provided to the row driver(26) and the other group of divided voltages(V0,V2,V3,V5) provided to the column driver(28). The LCD controller(24) generates control signals(COM_Cj,SEG_Ck) and inversion signals(IV) for controlling the row driver(26) and the column driver(28). The row driver(26) outputs one group of divided voltages(V0,V1,V4,V5) as common output signals(COMj). The column driver(28) outputs the other group of divided voltages(V0,V2,V3,V5) as segment output signals(SEGk). The common output signals(COMj) are used for selecting a row of an LCD panel(30).
    • 目的:提供用于减少串扰的LCD面板驱动器,以通过防止串扰提高LCD面板的对比度。 构成:LCD驱动器(20)从诸如个人计算机的系统单元的主机(10)接收处理的信息。 LCD驱动器(20)由分压器(22),LCD控制器(24),行驱动器(26)和列驱动器(28)组成。 分压器(22)产生提供给行驱动器(26)的一组分压电压(V0,V1,V4,V5)和提供给列驱动器的另一组分压电压(V0,V2,V3,V5) (28)。 LCD控制器(24)产生用于控制行驱动器(26)和列驱动器(28)的控制信号(COM_Cj,SEG_Ck)和反相信号(IV)。 行驱动器(26)输出一组分压(V0,V1,V4,V5)作为公共输出信号(COMj)。 列驱动器(28)输出另一组分压(V0,V2,V3,V5)作为段输出信号(SEGK)。 公共输出信号(COMj)用于选择LCD面板(30)的行。

    • PURPOSE: A liquid crystal display driver is provided to increase an application degree by inputting/outputting data by the usage of less input/output terminals. CONSTITUTION: A liquid crystal display system comprises a liquid crystal display, a micro controller, and a liquid crystal display driver. The liquid crystal display(300) displays an electrical signal by predetermined number or character and by a predetermined symbol. The micro controller(100) outputs a first group of control signals, serial data of plural bits, and a second group of control signals for the usage in the control of the liquid crystal display. The liquid crystal display driver(200) has the predetermined number of data input/output terminals. The driver receives the serial data of the plural bits to drive the liquid crystal display in response to the control signals of the second group.
    • 目的:提供液晶显示驱动器,通过使用较少的输入/输出端子输入/输出数据来增加应用程度。 构成:液晶显示系统包括液晶显示器,微控制器和液晶显示驱动器。 液晶显示器(300)以预定的数字或字符和预定的符号显示电信号。 微控制器(100)输出第一组控制信号,多位的串行数据和用于控制液晶显示器的第二组控制信号。 液晶显示驱动器(200)具有预定数量的数据输入/输出端子。 驱动器接收多个位的串行数据,以响应于第二组的控制信号来驱动液晶显示器。
