3、LCDs(AMLCD)DATA DRIVERSSCAN DRIVERS產品及生產流程簡介產品及生產流程簡介FIn an AMLCD display,each pixel has a TFT.The gate is attached to a horizontal row electrode and the drain is attached to a vertical column electrode.The source is attached to the LC electrode.FThe display is activated one row at a time,by activat

4、ing the gate lines.The column electrodes carry the data voltages.When a TFT is turned on,the data line charges up the LC capacitor to the appropriate voltage.Then the TFT is turned off,so that the charge is held on the capacitor until the next refresh time.(Typical refresh rates are 60-70 Hz)FThe da

5、ta voltage is isolated from the other rows of the display by the TFT,so that cross talk is very low,even when the number of rows is large.FThe overall effect is almost the same as being able to control the voltage at each pixels.Thus,any point on the transmission curve is accessible,leading to good
