    • Disclosed is a liquid crystal display panel driving circuit for driving a liquid crystal display panel with a resolution of N bits. N-bit digital data including upper X bits and lower Y bits is inputted. The liquid crystal display panel driving circuit includes a resistor string unit according to areas, a DAC converter switching unit according to areas, and an interpolation amplifier. The resistor string unit outputs analog reference voltages at different ratios according to three areas. The DAC converter switching unit receives the N-bit digital data, selects (Y+1) analog voltages from the analog reference voltages based on the upper X bits, outputs the (Y+1) analog voltages, and outputs the (Y+1) analog voltages of different combinations based on the lower Y bits. The interpolation amplifier receives the (Y+1) analog voltages and generates an interpolated output voltage by setting weights for the (Y+1) analog voltages by using multi-factors.
    • 公开了一种以N位分辨率驱动液晶显示面板的液晶显示面板驱动电路。 输入包括高X位和低Y位的N位数字数据。 液晶显示面板驱动电路包括根据区域的电阻串单元,根据区域的DAC转换器切换单元和内插放大器。 电阻串单元根据三个区域输出不同比例的模拟参考电压。 DAC转换器切换单元接收N位数字数据,从模拟参考电压基于高X位选择(Y + 1)模拟电压,输出(Y + 1)模拟电压,并输出(Y + 1) )基于较低Y位的不同组合的模拟电压。 内插放大器通过使用多因素设置(Y + 1)模拟电压的权重,接收(Y + 1)模拟电压并产生内插输出电压。
