  • Patent number: 11983848
    Abstract: Aspects of the disclosure provide a frame processor for processing frames with aliasing artifacts. For example, the frame processor can include a super-resolution (SR) and anti-aliasing (AA) engine and an attention reference frame generator coupled to the SR and AA engine. The SR and AA engine can be configured to enhance resolution and remove aliasing artifacts of a frame to generate a first high-resolution frame with aliasing artifacts and a second high-resolution frame with aliasing artifacts removed. The attention reference frame generator can be configured to generate an attention reference frame based on the first high-resolution frame and the second high-resolution frame.

  • Patent number: 11947215
    Abstract: A backlight module includes a housing, a light source, at least one supporting member, a diffuser plate, and an optical film. The housing includes a backplate portion, a sidewall portion, and a panel mounting platform. The sidewall portion is arranged along a periphery of the backplate portion. The panel mounting platform is connected and bent relative to the sidewall portion, such that the panel mounting platform, the sidewall portion, and the backplate portion form a concavity. The light source is disposed on the backplate portion. The supporting member is disposed in the housing and at least partially located in the concavity. The optical film and the diffuser plate are stacked on the supporting member. The supporting member has a reflective incline structure that is configured to directly reflect light traveling towards an inner side surface of the housing towards the diffuser plate.
