AI Technical Summary

⚠Technical Problem

In the prior art, the adhesive sheet used for the display body cannot simultaneously achieve both light shielding and light concealment in terms of the visibility and design of the displayed image, especially in display devices with direct-lit backlights, where the thermal effect of the light-emitting body leads to component deterioration.

⚗Method used

An adhesive sheet is provided, comprising a colored adhesive layer, having a brightness L* of 90 or less, a total light transmittance of 3% or more, and a thermal conductivity of 0.1 W/m·K or more. When used in a display, it can improve design when the light is off and ensure image visibility when the light is on, and suppress thermal degradation through excellent heat dissipation.

🎯Benefits of technology

It achieves improved aesthetic harmony and design when the display is off, while ensuring image visibility when the display is on, and suppresses thermal degradation near the light source through excellent heat dissipation.
