AI Technical Summary

Technical Problem

PDLC display devices suffer from decreased light transmittance and brightness due to light absorption by the common electrode and pixel electrodes.

Method used

The display device incorporates a pixel electrode layer with apertures and a common electrode layer with matching apertures, arranged in specific directions, to minimize light absorption and enhance transparency and brightness.

Benefits of technology

This configuration maintains uniform transparency and increases scattered light intensity, reducing absorption losses and enhancing overall brightness.
