    • A power generating module is provided in an LCD where the power generating module includes a first driving voltage generator, a second driving voltage generator and an output deviation controller. The first driving voltage generator generates and outputs a first set of LCD driving voltages including a first liquid crystal driving voltage and a first gate-on-voltage. The second driving voltage generator generates and outputs a similar second set of LCD driving voltages. The output deviation controller controls the first and second driving voltage generators using one or more feedback signals each corresponding to a potential difference between counterpart output voltages of the first driving voltage and the second driving voltage to reduce output deviations between those counterpart output voltages.
    • 发电模块设置在LCD中,其中发电模块包括第一驱动电压发生器,第二驱动电压发生器和输出偏差控制器。 第一驱动电压发生器产生并输出包括第一液晶驱动电压和第一栅极导通电压的第一组LCD驱动电压。 第二驱动电压发生器产生并输出类似的第二组LCD驱动电压。 输出偏差控制器使用一个或多个反馈信号来控制第一和第二驱动电压发生器,每个反馈信号各自对应于第一驱动电压和第二驱动电压的对方输出电压之间的电位差,以减小这些对应输出电压之间的输出偏差。

    • The present invention discloses a manufacturing method and apparatus of artificial human teeth using dental CT. The method comprises the steps of: removing a damaged part of human teeth; obtaining surface coordinates of the teeth using a dental CT machine located at a dental clinic for a medical checkup; converting the surface coordinates of the actual teeth to CAD/CAM data; manufacturing artificial teeth by cutting metal or ceramic with a three-dimensional N/C machine using the converted data; obtaining shape data of upper or lower actual teeth corresponding to the artificial teeth; changing the shape of the artificial teeth by direct surface processing according to the shape data of the upper or lower teeth; and coating ceramic to the artificial teeth after sintering the processed artificial teeth for a predetermined period.
    • 本发明公开了使用牙科CT的人造人牙的制造方法和装置。 该方法包括以下步骤:去除人牙齿的损伤部分; 使用位于牙科诊所进行体检的牙科CT机来获得牙齿的表面坐标; 将实际齿的表面坐标转换为CAD / CAM数据; 通过使用转换的数据用三维N / C机器切割金属或陶瓷来制造人造牙齿; 获得对应于人造牙齿的上或下实齿的形状数据; 根据上下牙齿的形状数据,通过直接表面加工改变人造牙齿的形状; 并在预定时间内烧结加工的人造牙后将陶瓷涂覆到人造牙齿上。
