Seiko Epson had six patents in internet of things during Q1 2024. The display device described in the patent includes a substrate, a lens layer with a lens, a pixel electrode, and a color filter. The color filter overlaps part of the pixel electrode and is located between the substrate and the lens layer. The pixel electrode is in the display region, with the lens overlapping part of it. The distance between the center of the pixel electrode and the display center is shorter than the distance between the center of the lens and the display center.

Application: Display device having lens corresponding to pixel, and electronic apparatus (Patent ID: US20240090301A1)
The patent filed by Seiko Epson Corp describes a display device with a unique configuration that includes a substrate, a lens layer with a lens, a pixel electrode, and a color filter. The color filter overlaps part of the pixel electrode and is positioned between the substrate and the lens layer. The pixel electrode is located in the display region where images are displayed, with the lens also overlapping part of the pixel electrode. The positioning of the lens and pixel electrode in relation to the display center is specified to optimize display performance.
The patent claims detail the specific components and their positioning within the display device, including multiple pixel electrodes, lenses, colored portions, and transmissive layers. The claims outline the arrangement of these elements in relation to each other and the display region, emphasizing the shift amounts and positions of the lenses and colored portions with respect to the pixel electrodes. Additionally, the claims introduce variations in refractive indices of different materials used in the device, as well as the thickness differences in colored portions and transmissive layers. The patent also extends to cover an electronic apparatus incorporating the described display device.
