APPARATUS FOR CONTROLLING CONTROL SIGNAL OF LIQUID CRYSTAL DISPLAY, IN WHICH A CONTROL SIGNAL IS CONTROLLED FROM EXTERNAL

摘要

PURPOSE: An apparatus for controlling a control signal of a liquid crystal display is provided to enable users to control the control signal easily and to correct a problem in a LCD module at any processing and fabrication step. CONSTITUTION: A LCD module device(400) comprises a liquid crystal panel(408) displaying a screen, and a timing controller unit(404) controlling data supply and a driving signal of the liquid crystal panel, and a voltage generator unit(406) generating a driving voltage, and an input unit(402) which is installed with a plurality of control signal pins controlled by an external control signal. A converter board device(300) comprises a scaler unit(302) and a power supply unit(304) supplying data and supply power required in the LCD module device. The scaler unit comprises a micom GPIO port which controls a plurality of control signal pins installed in the input unit.
