Pin Name
Output pins for sampled analog image signals. When driven with V
11.5 V
This pin reads the start pulse at the rising of CLK and starts sampling of analog
display signals in 12 channels simultaneously. The active edges of CLK are all
rising edges.
Analog image signal input pins. Please input analog display signals by inverting the
polarity for each display line.
The shift direction of the shift register is as follows.
R/L = H (right shift) ;
R/L = L (left shift)
R/L = H (right shift) ;
R/L = L (left shift)
R/L = H (right shift) ;
R/L = L (left shift)
S/D = L; When PL/NL = H, Both odd number pin and even number pin samples
S/D = H; When PL/NL = H, Odd number pin samples negative analog display signals
S/D = H; Complying with one side arrangement dot inverting.
S/D = L; Complying with both sides arrangement dot inverting.
This pin shuts off the output at the falling edge and then outputs analog display
signals at the rising. When HS = L, after the driver output pin goes to high impedance
this pin switches PL/NL and resets the internal hold capacity and output buffer to the
V
This pin shuts off the output buffer low current supply and increases the output
impedance. The LPC = “H” mode allows the static current consumption to be
reduced by approximately 20 %.
These pins control the current consumption of the output buffer by applying a
stabilized external power supply.
