DESCRIPTION The DLR/DLO/DLG2416 is a four digit 5 x 7 dot matrix display module with a built-in CMOS integrated circuit. This display is X/Y stackable. The integrated circuit contains memory, ASCII ROM decoder, multiplexing circuitry and drivers. Data entry is asynchronous and can be random. A display system can be built using any number of DLX2416s since each digit can be addressed independently and will continue to display the character last stored until replaced by another. System interconnection is very straightforward. The least significant two address bits (A0, A1) are normally connected to the like-named inputs of all displays in the system. With two chip enables (CE1 and CE2) four displays (16 characters) can easily be interconnected without a decoder. Data lines are connected to all DLX2416s directly and in parallel, as is the write line (WR). The display will then behave as a write-only memory. The cursor function causes all dots of a digit position to illuminate at half brightness. The cursor is not a character, and when removed the previously displayed character will reappear. The DLX2416 has several features superior to competitive devices. True "blanking" allows the designer to dim the display for more flexibility of display presentation. Finally the CLR clear function will clear the cursor RAM and the ASCII character RAM simultaneously.

Loading Data Setting the chip enable (CE1, CE2) to their true state will enable data loading. The desired data code (D0-D6) and digit address (A0, A1) must be held stable during the write cycle for storing new data. Data entry may be asynchronous and random. Digit 0 is defined as right hand digit with A1=A2=0.` To clear the entire internal four-digit memory hold the clear (CLR) low for 1.0 s. All illuminated dots will be turned off within one complete display multiplex cycle, 1.0 msec minimum. The clear function will clear both the ASCII RAM and the cursor RAM. Loading Cursor Setting the chip enables (CE1, CE2) and cursor select (CU) to their true state will enable cursor loading. A write (WR) pulse will now store or remove a cursor into the digit location addressed by A0, A1, as defined in data entry. A cursor will be stored if D0=1 and will removed if D0=0. The cursor (CU) pulse width should not be less than the write (WR) pulse or erroneous data may appear in the display. If the cursor is not required, the cursor enable signal (CUE) may be tied low to disable the cursor function. For a flashing cursor, simply pulse CUE. If the cursor has been loaded to any or all positions in the display, then CUE will control whether the cursor(s) or the characters will appear. CUE does not affect the contents of cursor memory. Display Blanking lanking the display may be accomplished by loading a blank or space into each digit of the display or by using the (BL) display blank input. Setting the (BL) input low does not affect the contents of either data or cursor memory. A flashing circuit can easily be constructed using a 555 as table multivibrator. Figure 4 illustrates a circuit in which varying R2 (100K~10K) will have a flash rate of 1.0 Hz~10 Hz. The display can be dimmed by pulse width modulating the (BL) at a frequency sufficiently fast to not interfere with the internal clock. The dimming signal frequency should be 2.5 kHz or higher. Dimming the display also reduces power consumption. An example of a simple dimming circuit using a 556 is illustrated in Figure 5. Adjusting potentiometer R3 will dim the display by changing the blanking pulse duty cycle.
