Notes:
1. Power supply voltage should not be changed after adjusting VCDC.
2. VR1, VG1, VB1, VR2, VG2, VB2 terminals (Video signal)
3. VBS, VR1, VG1, VB1, VR2, VG2, VB2 terminals
4. HSY, VSY, NTP, VSW, HRV, VRV, SAM CLKC, CLK terminals
5. HSY, VSY, CLK terminals (output mode)
6. CLK terminals (output mode)
7. Duty cycle is defined as follows.
8. VBS (horizontal sync. component)
9. VBS (vertical sync. component)
10. CLK (input mode)
11. HSY (input mode)
12. VSY (input mode)
13. In case of CLKC=Lo, it shows the phase difference from HSY to
CLK. In that case, HSY will be taken at the rise timing of CLK.
14. In case of CLKC=Lo. it shows the phase difference from VSY to
HSY. In that case, VSY will be taken at the rise timing of HSY.
15. Adjusting the optimal voltage on every module at the typical value
of power supply voltage to get the maximum value of contrast.
However, in the case that the power supply voltage is changed, for
example the level of power supply voltage is reduced, adjust it
externally to get the best contrast with a resistor you add to this
terminal, or semifixed resistor, VCDC, in module. A recommended circuit
is shown in Fig. 5.

Circuit Diagram
The circuit block diagram of TFT-LCD module is shown
in Fig. 4.
BRT, VCDC, external adjusting recommended circuit is
shown in Fig. 5.
Caution: Turn the power supply on or off (VSH and V SL) at
the same time. Be careful to supply all power voltage
before inputting signals.
Input/Output Signal Waveforms (Fig. 6)
Caution: For the VBS signal, input standard composite
video (or sync.) signal applicable to the operating mode
which have NTSC (M) or PAL (B-G) and is selected by
the NTP signal.
Dimming Backlight by PWM Timing Chart
If using PWM mode, refer to the timing chart shown in
Fig. 7.
