Symbol Description
Vcc2 Supply voltage (+11...+30V) converted
to required internal high voltages (see
J2).
Vcc1 Supply voltage (+5 V) for the logic (see
J2).
Reserved, do not connect.
GND Signal return.
TVID Second data input for two bit parallel
mode. The TVID input is for odd columns
and the VID for even ones.
VS The vertical sync signal VS controls the
vertical position of the picture.
HS The horizontal sync signal HS controls the
internal row counter and the horizontal
position of the picture.
VCLK The VCLK signal shifts data present on
the VID and TVID lines into the display
system. VCLK is active on the rising edge.
VID Signal that supplies the pixel information
to the system.
GND Signal return.
Vcc2 Same as J1, Pins 1, 2 (not necessary to
connect if power is supplied via J1).
GND Same as J1 Pins 6, 8, 10, 12, 14, 16 (not
necessary to connect if power is supplied
via J1).
Vcc1 Same as J1 Pins 3, 4 (not necessary to
connect if power is supplied via J1).
_LOWPWR The power consumption of the display is
lowered to LOWPWR values if the
_LOWPWR is low, internally pulled high if
left disconnected.
ENABLE The operation of the display unit is
disabled if the ENABLE input is low,
internally pulled high if left disconnected.
LUMPOT1 Input for external luminance control (see
page 8). Can be left disconnected.
LUMPOT2 Input for external luminance control. Can
be left disconnected.
Reserved, do not connect.
