7-segment LED Displays with High Energy Efficiency, Long Life Span

Seven-segment displays, which show numerical information, offer the benefits of LED technology such as energy efficiency and long life span. They are widely used in home appliances, audio equipment, digital clocks and timers, and electronic meters and instruments, including in the automotive industry.

To cater to this diverse application market, manufacturers of this optoelectronic component in China will continue to highlight customization of digit number and height, emitted color and display dimensions. This is while ensuring products meet industry standards such as high luminous intensity, wide viewing angle, low power consumption, and overall enhanced stability and performance.

Their typical selections of common-anode and -cathode types have one to eight digits, digit height of 0.28 to 0.8in, white segments and black or gray faces. In terms of emitted color, red, green, yellow, white, blue, amber and orange are common. These display modules usually have a life span of about 50,000 hours.

The key components and materials used in the production of 7-segment LED displays include LED chips, pins and cases. They are sourced from domestic or foreign providers, depending on the preferences of buyers.

The supply and costs of manufacturing inputs did not change much in the past 12 months, keeping product prices generally stable. This trend is expected to continue in the months ahead.
