    • A timepiece and chronometer with a superimposed analog/digital display arrangement. The timepiece comprises a watch case with a back and a display area, a transparent crystal, an electrically-driven digital LCD display, a superimposed analog display comprising an hour hand, minute hand, and interior bezel, an electrical analog watch movement, and a digital display driver. The digital LCD display indicates passing seconds by incrementally displaying either digits 00 through 59 or digits 01 through 60 for one second each, either in dark numerals over a light background, or vice versa. The analog display is driven by an electrical watch movement located beneath the LCD display that comprises a battery, a timing standard, timing circuitry, a stem and crown assembly, and a hand moving assembly that extends upward through the center aperture of the LCD display and couples to the analog watch hands. The digital display driver, also located behind the LCD display, couples to the digital LCD display and comprises a second battery, a timing standard, and timing and display driving electronic components and circuitry. The analog movement and the digital display driver may share the same electrical ground, but otherwise are electrically isolated from one another.
    • 具有叠加的模拟/数字显示装置的钟表和计时表。 该钟表包括具有背面和显示区域的表壳,透明晶体,电驱动数字LCD显示器,包括时针,分针和内饰板的叠加模拟显示器,电模拟手表机芯和 数字显示驱动。 数字LCD显示器通过逐渐显示数字00至59或数字01至60,每次显示一秒钟,以浅色背景中的深色数字显示通过秒数,反之亦然。 模拟显示器由位于LCD显示器下方的电气手表驱动器驱动,该电子手表机构包括电池,定时标准,定时电路,杆和冠组件以及向上延伸穿过LCD显示器的中心孔的手动组件, 情侣到模拟手表手。 也位于LCD显示器后面的数字显示驱动器耦合到数字LCD显示器,并且包括第二电池,定时标准以及驱动电子元件和电路的定时和显示。 模拟运动和数字显示驱动器可以共享相同的电接地,但是否则彼此电隔离。

    • A system and method for driving a liquid crystal display (LCD) having at least one segment. The system includes an LCD driver connected to a segment of the LCD. A processor is connected to the LCD driver. The processor may be selectively configured into any of at least two multiplexing modes, where the at least two multiplexing modes produce at least three voltage levels for driving the at least one segment of the LCD. Another embodiment includes a system and method for driving an LCD having a segment including a first and second electrode. An LCD driver is coupled to the first and second electrode. A processor is coupled the LCD driver. The processor initiates a substantially periodic signal on the first electrode and a delay signal having a time delay relative to the substantially periodic signal. The signals on the first and second electrodes form an RMS voltage to drive the segment of the LCD to any of at least three display voltage levels.
    • 一种用于驱动具有至少一个段的液晶显示器(LCD)的系统和方法。 该系统包括连接到LCD的一部分的LCD驱动器。 处理器连接到LCD驱动器。 处理器可以被选择性地配置成至少两种复用模式中的任何一种,其中至少两个复用模式产生用于驱动LCD的至少一个段的至少三个电压电平。 另一个实施例包括用于驱动具有包括第一和第二电极的段的LCD的系统和方法。 LCD驱动器耦合到第一和第二电极。 处理器与LCD驱动器相连。 处理器在第一电极上启动基本上周期性的信号,以及具有相对于基本周期性信号的时间延迟的延迟信号。 第一和第二电极上的信号形成RMS电压,以将LCD的段驱动到至少三个显示电压电平中的任何一个。
