    • A method and apparatus for providing a column driver circuit for an electroluminescent display panel including a column driver with a column driver including a direct analog interface with an input buffer with an input for accepting an external analog signal and an output for outputting an analog signal for said electroluminescent display panel. The buffer includes a polarity inverter and an adder for selectively inverting the external analog signal and adding a DC voltage. The column driver further includes an output demultiplexer, a plurality of sample and hold circuits, and an output driver employing negative feedback techniques for comparing the feedback signal to a preselected external variable voltage and selecting the appropriate drive signal.
    • 一种提供用于电致发光显示面板的列驱动电路的方法和装置,包括具有列驱动器的列驱动器的列驱动器,列驱动器包括与输入缓冲器的直接模拟接口,其具有用于接受外部模拟信号的输入端和用于输出模拟信号的输出, 所述电致发光显示面板。 缓冲器包括极性反相器和用于选择性地反转外部模拟信号并添加DC电压的加法器。 列驱动器还包括输出解复用器,多个采样和保持电路,以及采用负反馈技术的输出驱动器,用于将反馈信号与预选的外部可变电压进行比较并选择适当的驱动信号。
