Abstract
本公开实施例公开模数转换电路、集成芯片、显示装置及模数转换方法,第一转换电路对原始模拟信号进行转换,得到第一位宽的数字信号,分压电路对第一级模拟信号进行分压,得到第二级模拟信号,第一级模拟信号为原始模拟信号或与分压电路相邻的上一个分压电路得到的第二级模拟信号,第二转换电路根据预设算法对接收到的第二级模拟信号进行转换,得到第二位宽的第二数字信号,控制计算电路根据第一数字信号和第二数字信号,得到第三位宽的目标数字信号,由于目标数字信号的位宽大于第一转换电路得到的第一数字信号的位宽,也大于第二转换电路得到的第二数字信号的位宽,因此比现有技术中输出的数字信号的位宽高,从而能够提高输出的数字信号的精度。
