Patent number: 10983482Abstract: An electronic device such as a wristwatch device or other device may have a display. The display may be used to continuously display information such as watch face information. A watch face image on the display may contain watch face elements such as watch face hands, watch face indices, and complications. To reduce burn-in risk for watch face elements, control circuitry in the electronic device may impose burn-in constraints on attributes of the watch face elements such as peak luminance constraints, dwell time constraints, color constraints, constraints on the shape of each element, and constraints on element style. These constraints may help avoid situations in which static elements such as watch face indices create more burn-in than dynamic elements such as watch face hands.Type: GrantFiled: February 15, 2019Date of Patent: April 20, 2021Assignee: Apple Inc.Inventors: Tae-Wook Koh, Yiqiang Nie, Yifan Zhang, Giovanni M.

Patent number: 10930710Abstract: A display may have an array of pixels. Each pixel may have a light-emitting diode such as an organic light-emitting diode or may be formed from other pixel structures such as liquid crystal display pixel structures. The pixels may emit light such as red, green, and blue light. An angle-of-view adjustment layer may overlap the array of pixels. During operation, light from the pixels passes through the angle-of-view adjustment layer to a user. The viewing angle for the user is enhanced as the angular spread of the emitted light from the pixels is enhanced by the angle-of-view adjustment layer. The angle-of-view adjustment layer may be formed from holographic structures recorded by applying laser beams to a photosensitive layer or may be formed from a metasurface that is created by patterning nanostructures on the display using printing, photolithography, or other patterning techniques.Type: GrantFiled: November 2, 2017Date of Patent: February 23, 2021Assignee: Apple Inc.Inventor: Paul S.
