Smart LED display

Avago Technologies expands its line of smart dot-matrix 5-by-7 LED alphanumeric displays to include what it touts as the industry's first smart displays with eye-catching blue characters in a thin rectangular 8-character package. The HCMS-2919 and HCMS-2976 LED displays are about the width of a AAA battery.

Targeting designers who are looking to enhance the appearance of their products with blue display characters that are easy to see in all lighting conditions, the HCMS-2919 and HCMS-2976 smart dot-matrix LED products are available in eight character packages that can be stacked vertically or horizontally for displays that need high character counts. A transistor-transistor logic (TTL)-compatible serial interface is said to allow for the higher character count with a minimum of data lines.

The gallium nitride (GaN) blue (460nm dominant wavelength) smart displays are available in a 5-by-7pixel format that can display upper and lower case Roman letters, Katakana, and a wide range of user-defined characters. Typical brightness is 170cd per character (all pixels illuminated). It also features easy brightness control and operation over the extended temperature range of -40C to 85C.

The HCMS-2919 and HCMS-2976 displays are driven by on-board low-power CMOS ICs, and can be directly interfaced with a microprocessor, which eliminates the need for interface components, said the company. These displays can be used in a variety of consumer, industrial and communications applications such as remote battery-powered instruments, copy machines, printers, gaming machines, routers, audio/video applications and test and measurement equipment.

The HCMS-2919, 0.15-inch character height blue smart display is priced at $56.89, and the HCMS-2976, 0.20-inch character height smart display at $59.53, both in quantities of 10,000. Samples and production quantities are currently available.
