    • An optical scanner system and method having a light source, a first mirror rotatable along a first torsion axis to reflect light from the light source, a first vibrator to vibrate the first mirror, a second mirror positioned adjacent to the first mirror and rotatable along a second torsion axis different from the first torsion axis, a second vibrator to vibrate the second mirror, and a mirror reflecting the light reflected from the first mirror to the second mirror. In addition, microminiaturization may be further embodied by applying an MEMS technology. Further, a vibrating body may be designed to vibrate with high frequencies by reducing the size and mass of the vibrating body. Through embodiments of the present invention, it is also possible to prevent interference between light entering a mirror package and the finally reflected light.

    • Disclosed is a common voltage regulating circuit of a liquid crystal display device which can be adjusted by software, comprising: a pulse signal generating means for outputting a pulse width modulation signal in response to up/down signal for adjusting a common voltage; a smoothing means for smoothing a pulse width modulation signal to a direct current level provided from the pulse signal generating means; and an amplifying means for amplifying the signal smoothed by the smoothing means to a predetermined level and then outputting a common voltage signal. Accordingly, since a common voltage can be adjusted by software by means of a surplus pulse width modulation signal generated in an integrated board without installing a separate hardware, the common voltage can be easily adjusted. Further, since a variable resistor has not been used, not only manufacturing cost but also possibility of breakage can be reduced.
    • 公开了一种可通过软件调节的液晶显示装置的公共电压调节电路,包括:脉冲信号发生装置,用于响应用于调节公共电压的上/下信号输出脉宽调制信号; 平滑装置,用于将脉冲宽度调制信号平滑到从脉冲信号发生装置提供的直流电平; 以及放大装置,用于将由平滑装置平滑的信号放大到预定电平,然后输出公共电压信号。 因此,由于可以通过软件通过在集成电路板中产生的多余的脉冲宽度调制信号来调整公共电压而不安装单独的硬件,所以可以容易地调整公共电压。 此外,由于不使用可变电阻器,不仅可以降低制造成本,而且可以降低断线的可能性。
