Page 5: General Information
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 S3858–21–205. Description The Daystar Nova module is a self–contained 1/16 multiplexed unit. -
Page 6: Logical Structure And Function
LOGICAL STRUCTURE AND FUNCTION LCD Module 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 Adj.) at Pin 4, and connections for optional BIAS RESET and self–test switches at Pins 3 and 5. -
Page 7: Lcd Controller
LCD Controller The LCD Controller includes all of the circuitry necessary to take parallel input data and create the necessary control functions and characters. The block diagram of the controller is shown in Figure 2 below. The remaining subparagraphs of Section 2 describe the major function blocks. Address Timing Generation Counter (AC) -
Page 8: Character Generator Rom (Cg Rom)
2.2.6 Character Generator ROM (CG ROM) The CG ROM generates character patterns of 5 X 7 dots from 8 bit character codes. The 192 5 X 7 dot matrix characters are illustrated in Figure 3. Figure 3 Correspondence Between Character Codes and Character Patterns Note: Addresses 00h through 0Fh are reserved for CG RAM Addressing. -
Page 9: Character Generator Ram (Cg Ram)
2.2.7 Character Generator RAM (CG RAM) The CG RAM allows the user to define 8 types of 5 X 7 character patterns. Figure 4 shows the relationship between CG RAM addresses and data patterns (Refer to Set CG RAM Address and Write to CG or DD RAM instructions). -

Page 11: Power Up Instructions Sequence
Power Up Instructions Sequence Upon power up, the Daystar Nova module is set to a default mode of operation. Under some power up circumstances, the default mode may be improperly set. Consequently, the following instructions should always be executed in the host systems initialization routine. Step Operation Function Set for 8 bits... -

Page 20: El Backlighting
EL BACKLIGHTING EL Backlight Description The module contains an AC EL backlight which enables the LCD to read under low lighting conditions. The EL lamp provides uniform lighting across the entire display surface. Since the lamp is a cold light source, no heat is added to the module during operation. -
Page 21: Intermittent Operation
7.3.2 Brightness, Voltage and Frequency Characteristics (Continued) 25ºC, 115 VRMS, Aviation Green Frequency (Hertz) Figure 20 Initial Brightness vs. Frequency 7.3.3 Intermittent Operation The EL backlight is intended for intermittent usage only. Continuous operation will result in greatly reduced life of the lamp. -
Page 22: Electromagnetic Interference (Emi)
7.5. The brightness values are measures of the lamp surface brightness. The transmitted light through the LCD is approximately 8% of the lamp surface brightness. 25ºC, Aviation Green Time (Hours, 000's) Figure 21 Brightness vs. Time Electromagnetic Interference (EMI) Electroluminescent lamps have been shown to radiate negligible interference through UHF when operated by quasi–sinusoidal waveforms. -
Page 23: Installation Note
INSTALLATION NOTE To protect the front polarizer from accidental damage it is highly recommended that the LCD be mounted behind a clear glass or polycarbonate window material. It is also recommended that an air gap of at least .030" to .050" minimum be provided between the window material and the surface of the LCD to prevent the transfer of static charges to the front surface of the LCD. -
