The circuit in Figure 1 uses only five I/O lines to drive a dot- or bar-graph display of 20 LEDs. Although this version of the design uses a small and inexpensive one-time-programmable microprocessor, ...

This circuit uses two National Semiconductor LM3914 dot/bar-display-driver ICs to implement a two-digit, 0 to 5V LED voltmeter that mimics a subranging flash ADC. An LED bar graph comprising five LEDs ...

Choosing the appropriate digital display form is one of the most important decisions made by a B2B retail technology manager, ...

When it comes to big, bright visuals, nothing beats direct-view LED. Long relegated to select high-profile applications like stadium jumbotrons and Times Square billboards, recent years have seen ...
