DISPLAY PANEL DRIVING DEVICE FOR REDUCEING THE DIFFERENCE IN SLEW RATE AMONG DATA LINES

摘要

PURPOSE: A display panel operating device reducing a slew rate deviation between data lines is provided to reduce a slew rate deviation between data lines by operating the data lines by using the same reference current. CONSTITUTION: A main source driver chip(MCHP) receives image data(DIM) provided from the outside of a driver package(PKG). The main source driver chip operates a data line(DL) included in a line group(GDLM). The main source driver chip generates reference currents(IR) having the same value. A plurality of slave source driver chips(SCHP) receive the image data. The slave source driver chips operate the data line included in another line group(GDLS).
