AI Technical Summary
Existing optical sheets for light guide plate type liquid crystal displays face reduced light utilization efficiency due to the use of low refractive index layers that are not sufficiently low, leading to inadequate total reflection and increased optical characteristics when integrating optical films without air layers.
Incorporating a low refractive index layer with a refractive index of 1.25 or less, integrated via pressure-sensitive adhesive layers, which maintains optical characteristics and reduces thickness without a base, while protecting the layer from physical damage.
Enhances optical performance, reduces thickness, and improves assembly yield by integrating optical films without air layers, maintaining transparency and strength through adhesive layers.
