DATA DRIVING CIRCUIT OF LIQUID CRYSTAL DISPLAY PANEL, LIQUID CRYSTAL DISPLAY PANEL, AND LIQUID CRYSTAL DISPLAY APPARATUS

摘要

A data driving circuit of a liquid crystal display panel comprises a data driving chip (30). The data driving chip (30) comprises multiple data driving modules (21) for driving data lines of the liquid crystal display panel. Each data driving module (21) comprises a port (26) for defining a working voltage range of the data driving module (21). The data driving circuit of the liquid crystal display panel also comprises at least two isolation driving modules (10). Each isolation driving module (10) outputs a preset reference voltage to the port (26) of the corresponding data driving modules (21).
