INTERFACE IC FOR ACTIVE MATRIX LIQUID CRYSTAL PANEL

F11

Frequency characteristics 1

In inputting sync+sweep waveform (500mVP-P), measure the

cutoff frequency of each channel when pin022 is grounded.

Also, measure in the same way as above when pin 7 is

connected to GND and the mode is changed to EXT.

F21

Frequency characteristics 2

In inputting sync+sweep waveform (500mVP-P), measure the

cutoff frequency of each channel when voltage at pin 22 is 4.5V.

Also, measure in the same way as above when pin 7 is

connected to GND and the mode is changed to EXT.

CC1

Crosstalk among channels

Input sync+1.0MHz (500mVP-P) only to pin 1 and measure the

amplitude of output waveform, VR, VG, and VB, at pins 17 , 19 ,

and 21 respectively. Crosstalk is calculated as follows.

M=20

CS1 MAIN/EXT crosstalk

Input sync+1.0MHz (500mVP-P) only to pin 7 and measure the

amplitude of output waveform at pin 21 (VMR). Then, connect

pin 7 to GND and measure the output amplitude when the

same signal is input (VER). Crosstalk is calculated as follows.

Note 4:

When contrast and sub contrast parameters are measured, input

signal is set to 0.2VP-P because a limiter may work when normal

input signal is input.
