Common-anode and -cathode 7-segment LED displays usually have 0.28 to 4in digit height. Customization is still widely accepted.
From a maximum of seven digits in 2017, mainland China's typical range of common-anode and common-cathode 7-segment LED displays now has as many as eight. Products have 0.28 to 4in digit height and come in emitted colors such as red, orange, yellow, green, white and blue. There are dual- and tricolor variants as well. As for surface colors, black and gray are the choices, while a white diffused lens is standard.
Specifications can be customized as required, and such displays account for 50 to 90 percent of shipments.
The key applications include home appliances, industrial control and military equipment, with products in the smart living and new energy trends added in recent years. Shenzhen Guangzhibao Technology Co. Ltd has integrated Wi-Fi access control in its models for smart water dispensers. Zhongshan Jewelly Optoeletric Technology Co. Ltd has a new model for home appliances and electric meters, which measure 2.2mm in thickness.
Local makers use InGaN, GaN and InGaAIP chips from Taiwan and US companies or homegrown providers such as San'an. LEDs, PCBs, cases and other inputs come from domestic sources.
The cost of materials, components and labor increased in 2018, which pushed up product prices by 5 to 10 percent. In the months ahead, rates are projected to stabilize.
The products in this gallery have been handpicked by our market analyst for representing current trends in 7-segment LED displays from mainland China makers.
