A glass plate structure includes: a glass plate having first and second major surfaces; an antireflection film; and a print portion. The first major surface includes: a curved surface region that is a region of an end portion of the glass plate, is curved convexly, and has a radius of curvature r that is 50% or more of a thickness t of the glass plate; and a flat surface region that is connected to the curved surface region. The antireflection film is a laminate in which a high refractive index layer and a low refractive index layer are laminated alternately. The number of layers of the antireflection film is 12 or smaller. A total thickness of the antireflection film in the flat surface region is 400 nm or smaller. A thickness of an outermost layer of the antireflection film in the flat surface region is 90 nm or larger.

A color developing structure that exhibits good color development and ensures a desired transmittance while diffusing reflected light in multiple directions. A color developing structure includes a concave-convex layer in which a first surface has a concave-convex structure, and a reflective layer formed on the first surface to extend along the concave-convex structure. A convex surface of the concave-convex structure has a first pattern composed of a plurality of strip portions in plan view. The strip portion has a width in a first direction and a length in a second direction perpendicular to the first direction. The width is smaller than the wavelength of the incident light, and a standard deviation of the lengths of the plurality of strip portions is larger than a standard deviation of the widths.

Various embodiments provide a method for fabricating a couplable electro-optical device. In an example embodiment, the method includes fabricating at least one raw electro-optical device on a substrate; applying lens material to a working stamp; aligning the substrate and the working stamp; pressing the substrate onto the lens material until the distance between the substrate and the working stamp is a predetermined distance; and curing the lens material to form an integrated lens secured to the at least one electro-optical device on the substrate. An anti-reflective coating layer may be optionally applied on top of the molded lens. The couplable electro-optical device may be incorporated into a receiver, transmitter, and/or transceiver using passive alignment to align the couplable electro-optical device to an optical fiber.

An optical laminate is provided. When the optical laminate is applied to an OLED display device, the problem of visibility due to reflection of external incident natural light of the device can be solved, and simultaneously its display quality can also be improved.

Provided is an optical laminate produced by disposing an anti-glare layer on at least one side of a light-transmitting substrate, the anti-glare layer having a surface that has the arithmetic mean peak curvature Spc of 1.5 mm.sup.−1 or less in absolute value, the optical laminate has the adjusted transmission image clarity of 85% or less. On the anti-glare layer, further disposed is a low refractive index layer. The optical laminate including the low refractive index layer may have a luminous reflectance of 1.4 or less. The optical laminate improves the anti-glare properties.

Disclosed are RCLED lamp bead packaging process and RCLED lamp bead, which comprises steps of: dispensing a die-bonding glue, mounting a chip, baking, welding a bonding wire, dispensing a first layer of anti-reflection adhesive, baking, dispensing a second layer of anti-reflection adhesive, baking, and testing. Anti-reflection adhesive is dispensed in corresponding area to cover part capable of reflecting light in RCLED lamp bead and eliminate reflection effect effectively. The first layer of anti-reflection adhesive fills in specified area rapidly to achieve high production efficiency. The second layer of anti-reflection adhesive flows slowly after glue dispensing, so that the glue dispensing precision is improved and the light-emitting hole is prevent from being covered. When bonding wire is welded, a bracket is the first welding spot and a PAD of the chip is the second welding spot to achieve a lower radian of the bonding wire.
