High-brightness amber output on a 0.12-inch platform with a 3.75 μm pixel pitch

Hongshi has introduced a 585 nm amber MicroLED microdisplay, developed in response to customer demand for this specific wavelength and color. Built on the company’s 0.12-inch platform with a 3.75 μm pixel pitch, the new product expands the color options available in Hongshi’s microdisplay portfolio.

Achieving high brightness at the requested wavelength was a key development challenge. Hongshi has demonstrated high-brightness amber output and image display on the device, bringing the requested color from material development to a working microdisplay.

The product uses quantum dot (QD) materials formulated and prepared in-house by Hongshi. A quantum dot photoresist (QDPR) color-conversion process produces the target amber emission, combining the company’s proprietary quantum dot technology with its existing microdisplay platform.

The development connects material formulation and preparation with device integration, providing a new option for microdisplay projects with specific spectral requirements.
