6.2 Circuit Operation Theory 

I. Introduction: 

 

           X193HQL  is  a  18.5  inch  Wide  and  24bits  color  TFT  LCD  monitor,  which  can 

support  the  resolution  up  to  1366  x  768.  It  has  VGA  input  and  compliant  with  VESA 

specification to offer a smart power management. The monitor has DDC/CI function to 

make  the  monitor  communicate  with  PC  by  Acer  ADM  DDC/CI  software,  and  also  it 

has ACM function to let the monitor contrast ratio up to  ?:1. It also offers OSD Menu 

for users to control the adjustable items and get some information about this monitor. 

 

II.

 

Block diagram 

X193HQL consists of a main body and a stand (base). The main body contains a AUO/ 

LGD/SEC  TFT  LCD  module  with  LED  Backlight,  a  power  board  (includes  AC/DC

、

 

DC/DC

、

  inverter  and  panel  power  source),  a  control  board  and  an  interface  board.
