This errata specification provides additional information and corrections for interfacing and
programming the Optrex DMC-50747NF-AK display.
It is preferred the display is run as a 3.0 V device. The display is operable with logic levels of up
to 5.5 V.
Section 2.2 DC characteristics states the reader should refer to Section 3.1 for the Vlcd value.
Vlcd is based upon the difference between Vdd and the Vout voltage which must be externally
supplied.
For a 3.3 V system, supply, please supply at least -2.4 V to -4.0 V at the Vout pin to meet the
Vdd-Vout range of 5.6 V to 7.3 V over the operating temperature range.
For a 5.0 V system, supply, please supply at least -0.7 V to –2.3 V to Vout.
A source for inverting DC to DC converters can be found at www.linear.com.
The display does not use the internal DC to DC inverting boost circuit for the LCD drive voltage.
Note 1 in Section 2.2 regarding triple boost should not be construed to imply the drive voltages
are generated onboard.
The display uses a Seiko Epson S1D12303 LCD controller-driver. The programming of this
device is not covered in the
www.optrex.com. To program the display, please download reference (c) at:

The Section 4.2 Example of Power Supply is not correct. Please refer to Figure 1 for the correct
hookup. By varying the potentiometer, LCD contrast can be controlled. Please note that this
setup is shown at the bottom of page 4-20 of reference (c) for the instance of ‘External Power
Supply.’
