简 介:The DLO4135/DLG4137 5 x 7 Dot Matrix Intelligent Display Appnote 28
This application note is intended to serve as a design and application guide for users of the DLO4135 and DLG4137 OSRAM Intelligent Displays. This appnote covers device electrical description, operation, general circuit design considerations, and interfacing to microprocessors. Electrical Description The DLO4135/DLG4137 Intelligent Alphanumeric 5x7 Dot Matrix Display contains memory, character generator, multiplexing circuits, and drivers built into a single package. Figure 1 is a block diagram of DLO4135/DLG4137. The unit consists of 35 LED die arranged in a 5x7 pattern and a single CMOS integrated circuit chip. The IC chip contains the column drivers, row drivers, 128 character generator ROM, memory, multiplex and blanking circuitry. Figure 1. DLO4135/DLG4137 block diagram
