AI Technical Summary
The display panel failed to meet the High Dynamic Range (HDR) 500 specification requirements in optical testing, and the black level brightness value could not reach the standard value, resulting in extremely poor display effect and reduced user experience.
Nanoscale spherical microcavities are set on the carrier film of the touch panel, and light-absorbing materials are deposited in some areas of the inner wall of the microcavities to reduce light reflection and scattering. Black ink is deposited through chemical vapor deposition to improve the light focusing effect, and blackening treatment is applied to the surface of the touch signal lines to absorb stray light.
It improves the accuracy of black state brightness value testing, meets HDR testing standards, improves display effect, and enhances user experience.
