A display device includes a display panel including a light emitting region and a peripheral region adjacent to the light emitting region; an organic layer disposed on the display panel and having an opening that overlaps the light emitting region; and an adhesive layer disposed on the organic layer. The adhesive layer includes a first adhesive layer including a first base resin and having a first refractive index; and a second adhesive layer disposed on the first adhesive layer and having a second refractive index less than the first refractive index.

Provided is a PSA sheet having limited light transmission, an increased refractive index and good adhesive properties. The PSA sheet provided by this invention has a PSA layer. The PSA sheet has a total light transmittance below 80%. The PSA layer has a first face and a second face on the opposite side to the first face. The PSA layer comprises high-refractive-index particles. In the PSA layer, the high-refractive-index particles are concentrated in a range that extends from the first face towards the second face side and has a thickness of at least 100 nm, accounting for less than 50% of the PSA layer thickness.

An aerospace component may comprise a fiber reinforced composite material. The fiber reinforced composite material includes a plurality of fiber layers and a carbon matrix surrounding the plurality of fiber layers. A plurality of ceramic particles is dispersed in the carbon matrix. A first fiber layer of the plurality of fiber layers may include a carbon fiber, and a second fiber layer of the plurality of fiber layers may include a non-carbon fiber. A hardness of the non-carbon fiber is greater than a hardness of carbon fiber.

Disclosed is a method for preparing an eye-protecting screen protector, which aims to address the issues of reduced luminous efficiency, color fading and shortened life of nano-luminous materials in existing products due to moisture and oxygen penetration. This method involves binding inorganic nanoparticles with surface hydroxyl groups with nano-luminescent materials through cross-linking materials. After raw material preparation, adhesive mixing, coating and curing, and glass lamination, a dense microscopic barrier structure is formed after UV curing, effectively blocking moisture and oxygen. Nano-luminescent materials can absorb 400 nm-480 nm harmful blue light and convert it into 500 nm-750 nm beneficial spectra to achieve eye protection. The product structure from outside to inside consists of tempered glass, a light conversion layer, a PET transparent film, a silicone layer and a release film, and is suitable for electronic devices including mobile phones and tablets, combining long-term stability with efficient eye-protecting performance.
