  • Patent number: 11555951
    Abstract: A display device includes a cover structure, a light guide plate, and a display panel. The cover structure includes an anti-glare layer, a light blocking frame, and an adhesive layer. The anti-glare layer has a display region and an non-display region. The light blocking frame surrounds a receiving space. An orthogonal projection of the light blocking frame on the anti-glare layer is located within the non-display region. An adhesive layer is located in the receiving space of the light blocking frame. The light guide plate is located on the surface of the adhesive layer facing away from the anti-glare layer. The display panel is adjacent to the light guide plate.

  • Patent number: 11042070
    Abstract: A cover plate structure includes a first light transmitting layer, a second light transmitting layer, and a light shielding layer. The first light transmitting layer includes a top surface and a bottom surface opposite the top surface. The second light transmitting layer is on the top surface of the first light transmitting layer. A refractive index of the first light transmitting layer is greater than a refractive index of the second light transmitting layer. The light shielding layer is on the bottom surface of the first light transmitting layer.
