Description

This sunlight viewable 5 x 7 LED four-character display is contained in 12 pin dual-in-line packages designed for displaying alphanumeric information. The display is designed with on-board CMOS integrated circuits. Two CMOS ICs form an on-board 28-bit serial-in/parallel-out shift register with constant current output LED row driv- ers. Decoded column data is clocked into the on-board shift register for each refresh cycle. Full character display is achieved with external column strobing.
