AI Technical Summary
Technical Problem
Microdisplay devices suffer from high dead lamp rates, insufficient brightness, and inadequate display contrast, primarily due to short circuits caused by metal enclosures and optical crosstalk between pixels.
Method used
In a microdisplay device, a light-blocking component is set up so that it is suspended above the bottom conductive layer and insulated from it. At the same time, a recess in the top conductive layer is located between adjacent sub-pixels to block light and prevent short circuits.
Benefits of technology
It effectively reduces the dead lamp rate, improves display brightness and contrast, enhances luminous efficacy, prevents optical crosstalk, and improves device reliability.
