1.1
This specification describes the parallel interface Daystar Nova model 03875–21–0114, a 4–line supertwisted
liquid crystal display (LCD) with 40 characters per line.
Model Number Designation System
* Parallel standard, Serial optional
1.2
Daystar Nova modules provide alphanumeric information which is easily readable in high ambient light or in
darkness with Fiber Optic (FO) backlight activated. The low power requirements of the modules make them
suitable for portable battery operated equipment. The wide operating temperature range (–30° to +80°C) is
ideal for most outdoor applications. The choice of a preferential viewing hemisphere is not necessary because
of the excellent wide angle viewing characteristics of the new Super Bi–refringent Effect (SBE) liquid crystal cell
used in this display.
For applications where the display is remotely located up to 50 feet from the host processor, the serial data
input option should be used. The serial model is described in IEE specification S3875–21–0214.
1.3
The Daystar Nova module is a self–contained 1/16 multiplexed unit. A simple parallel interface is provided and
can be configured as either 4 or 8 bits. The on–board microprocessor controls the display, multiplexing and
character decoding. The temperature compensation circuitry guarantees that the viewing characteristics are
optimized for all temperatures.
The SBE liquid crystal cell used in this display has a golden–green background with dark blue–black
characters.
The on–board character generator ROM generates 192 types of alphanumeric, numeric, katakana characters
and symbols. In addition, a character generator RAM allows the user to define eight additional characters.
A variety of high level functions allow the programmer to operate the display with simple and straightforward
software routines. One such feature automatically increments the character display position after each
character is written.
A single +5 Volt nominal power supply is required for operation of the LCD module. The unit operates from 4.50
Volts to 5.50 Volts. The typical power requirement for the module is 75mW.
The module weighs 8.9 oz. (252 grams).

Figure 1 illustrates the major components of the serial option Daystar Nova module. The module provides
means for an external viewing angle adjustment potentiometer (V
RESET and self–test switches at Pins 3 and 5. The external viewing angle adjustment potentiometer should be
connected to the same +5 Volt supply as the display module. RESET and TEST pull down to ground to
activate the function. All three inputs may be left open if not used. The V
preset the viewing angle. The LCD Controllers are microprocessor units (MPU) designed specifically to control
all multiplexing and character decoding functions for the LCD display.
