Diversified technology paths for dimming glass, each with its own strengths

There are many technical paths for dimming glass, and currently, there are still multiple paths running side by side. Each technical path also has its own advantages and disadvantages. The four technical paths are PDLC, EC, SPD, and LC/Dye LC. PDLC is the earliest dimming glass technology. Its advantages are relatively mature development, low cost, fast color change response speed, and the ability to achieve zoned color adjustment.
