EMAN patent to be published soon

Microdisplay with reduced pixel size and method of forming same
 
Notice of Allowance on 1/15/20
 
 
and fees paid on 2/4/21 .
 
A couple interesting things about this one .
 
1. It will allow reduced pixel sizes -  
 
Thus, the present invention enables the fabrication of OLED-based microdisplays with higher pixel densities than prior microdisplays. 
 
The present invention enables an OLED microdisplay having pixels that include small sub-pixel areas as small as 2 μm×2 μm (an area of 4 μm2) or smaller. 
 
For Apple to make an 8K per eye HMD they need a display with smaller pixels . 
 
2.  2 of the Patents Cited by the EMAN patent are by TSMC -
 
 
 
- working from the same script ? 
 
This is also interested from the EMAN patent -
 
"The uniformity compensation circuitry preferably includes low voltage transistors (not shown) used for generating a local correction signal to the input data to ensure identical brightness performance among pixels despite process or aging related variations in drive transistors 206 and/or OLEDs 208 between different pixels." 
 
I remember Guttag recently saying brightness uniformity with micro LED was a big problem. 
 
@ 1:48:54 -
 

"Poor pixel to pixel brightness uniformity"
