  • Patent number: 12259612
    Abstract: A light control film and a display panel are provided. Light blocking members of the light control film are disposed on a side of a first base material layer, and light transmissive regions are defined between the light blocking members. Light transmissive members are filled in the light transmissive regions. Light control members are disposed on the light transmissive members corresponding to the light transmissive regions and are configured to decrease light emission angles of light passing through the light transmissive members. Therefore, when a specific light emission angle is realized, an area of the light transmissive regions can be increased to remedy a problem that a low light transmittance rate exists in current anti-peep films.

  • Patent number: 12259618
    Abstract: A display panel and a display module are provided. The display panel includes a non-display area, a central display area, and a peripheral display area arranged between the two areas. A counterpart substrate is arranged opposite to an array substrate, with a liquid crystal layer positioned between the array substrate and the counterpart substrate. A meta-surface structure layer of the counterpart substrate is arranged in the peripheral display area. Light emitted from the peripheral display area is at least partially deflected by the meta-surface structure layer and then emerges from the non-display area. The meta-surface structure layer in the peripheral display area alters the propagation path of light, allowing at least part of the light emitted from the peripheral display area to enter the non-display area. This approach overcomes the limitations imposed by a frame, enlarges the display area of the display panel, and achieves a narrow-frame display panel.
