Shanghai-based Micro-LED microdisplay developer JBD unveiled two new Micro-LED microdisplay prototypes. First up is the JBD5UM720P-G, a 0.31" 720p (1780x720, 5,000 PPI) display that features a typical brightness of 3 million nits (!). This is a monochrome green (530 nm) display.
The second display, the JBD25UMFHD-B is a higher density display, at 10,000 PPI it achieves a 2560x1440 resolution in the same 0.31" size. This is a monochrome blue (455 nm) display that has a brightness of 150,000 nits. The display's refresh rate is 360Hz.

Ok what is going on with
Ok what is going on with these contrast ratios?
10000:1 seems low. Isn't MicroLED supposed to be Infinite:1 like OLED?
Meaning that if a display is let's say 300 nits contrast ratio should be 300000:1 or something like that?
Also I see colors other than Blue or Green there such as White as well so how is it Monochrome Green and Monochrome Blue?
