Notes:
1. If CLKC=Hi, this terminal outputs horizontal sync. signal in phase with VBS.
If CLKC=Lo, this terminal will be external horizontal sync. input terminal.
2. If CLKC=Hi, this terminal outputs vertical sync. signal in phase with VBS.
If CLKC=Lo, this terminal will be external vertical sync. input terminal.
3. PWM signal is used for the PWM dimming frequency and it is easy to get PWM signal dimming by combining both HSY and PWM signal. But
use this PWM signal in case of input standard NTSC or PAL signal.
4. This terminal is to switch the display mode, and it is NTSC mode when NTP is High and is PAL mode when NTP is Low.
5. When this terminal is High, it will be normal and when it is Low, it will display reversely on the horizontal direction.
6. When this terminal is High, it will be normal and when it is Low, it will display reversely on the vertical direction.
7. This terminal is to switch input for groups of RGB color video signals, and Input 1 (No. 13 to 15) is selected when VSW is High and Input 2
(No. 17 to 19) is selected when VSW is Low.
8. This terminal switches the sampling mode. It is the independent data-sampling timing at RGB dots when SAM is High and it is the
simultaneous data-sampling timing at RGB dots when SAM is Low.
9. This terminal is applicable to the DC bias voltage adjusting terminal of the common electrode driving signal. If power supply voltage is typical, it
is not necessary to re-adjust it. So, use it in the open condition. However, in the case that the power supply voltage is changed, or power
supply voltage is reduced, adjust it externally to get the best contrast with a resistor that is added to this terminal, or semi-fixed
resistor, VCDC in module. A recommended circuit is shown in Fig. 5.
10. The sync. signal which will be input, is negative polarity and is applicable to standard composite sync. signal, negative one in the same pulse level.
11. DC voltage supplied to this terminal, makes the brightness of the screen adjustable, which is the black level of the video signal. Although this
is adjusted in the time of delivery to get the best display in the condition of the open terminal, it is also able to be re-adjusted externally with a
resistor that can be added to this terminal, or a semi-fixed resistor, BRT, in module. A recommended circuit is shown in Fig. 5.
12. CLKC=Hi, CLK.HSY.VSY terminals are output mode. CLKC= Lo : CLK. HSY. VSY terminals are input mode.
13. If CLKC=Hi, this terminal outputs the clock for source drivers. If CLKC=Lo, this terminal will be the external clock input terminal.
