AI Technical Summary
Technical Problem
In OLED display products that use color filter technology, display defects caused by the encapsulation layer structure, especially the bright streaks in the aperture structure that appear in dark conditions.
Method used
By setting a first vacancy structure in the second sub-part of the first electrode and a second vacancy structure in the second electrode layer, the reflection and diffraction effects of ambient light are reduced, and the bright fringe phenomenon of the aperture structure in the dark is improved.
Benefits of technology
It effectively reduces the bright lines phenomenon of the aperture structure in dark conditions, and improves the display efficiency and contrast of the display substrate.
