  • Publication number: 20250085583
    Abstract: Provided is a display panel, including: a base substrate, a display structure, a black matrix pattern, and a cylindrical lens structure layer. The black matrix pattern includes a plurality of first openings. The display panel is provided with a plurality of sub-pixel regions arranged in rows and columns. The first openings are disposed in the sub-pixel regions. The cylindrical lens structure layer includes a plurality of strip-shaped cylindrical lens structure and has a plurality of focal lines in an orthographic projection on the black matrix pattern. The focal lines are parallel to the length direction of the cylindrical lens structures. The focal lines partition each sub-pixel region into a plurality of regions. One of the plurality of regions is a non-crosstalk region. The black matrix pattern further includes second openings in the non-crosstalk regions. The second openings are disposed outside regions where the first openings are disposed.

  • Patent number: 10808761
    Abstract: A rolling bearing includes an inner ring, an outer ring, and rolling elements interposed between the inner ring and the outer ring. A surface layer portion, beneath a raceway surface (10a), of a base material of a raceway ring (10) which is the inner ring or the outer ring, is a wear-resistant layer (13) which has a higher hardness than a residual portion (12), beneath the surface layer portion, of the base material, and includes a minute-recess-and-projection surface. An oxide film (14) is provided which has such a film thickness (t) as to fill recesses of the minute-recess-and-projection surface of the wear-resistant layer (13), and includes recesses and projections existing along the minute-recess-and-projection surface, and the oxide film (14) coats the surface of the wear-resistant layer (13). The oxide film (14) is made from a material more fragile than the wear-resistant layer (13) of the base material.
