Other companies are exploring the possibility of packaging 3 LEDs: one red, one green and one blue LED into a single package to reduce mass transfer costs. [ 63 ] [ 64 ] Quantum dots are being researched as a way to shrink the size of microLED pixels, while other companies are exploring the use of phosphors and quantum dots to eliminate the ...
The size of the Mini Small Outline Package is only 3mm × 3mm for the 8 and 10 pin versions [1] and 3mm × 4mm for the 12 and 16 pin version. [2] [3] The small package offers a small footprint, short wires for improved electrical connections, and good moisture reliability. [1] Some versions have an exposed pad on the bottom side.

While the company makes various proprietary and industry-standard connectors, they are best known for a small coaxial connector which has become known as "the" Microdot connector. In its most common version, called the S-50 series, it uses a 10-32 (0.190-32 UNF2B) thread.
The Worth Four Light Test is relatively simple to undertake. First you must place the red/green goggles over the patients eyes, with the red goggle traditionally placed over the right eye. Red Green Goggles used in the Worth Four Light Test. Next you must dim the room lighting. This allows the patient to see the lights better.
