Plastic cover lens and display for vehicle including the same
Disclosed is a display for a vehicle including a plastic cover lens including a lens, a front film disposed on a front surface of the lens, and a rear film disposed on a rear surface of the lens, a super retardation film (SRF) adhered to a rear surface of the plastic cover lens using an optically clear adhesive (OCA), a liquid crystal display module adhered to a rear surface of the super retardation film using the optically clear adhesive, a panel-front assembled at the rear of the plastic cover lens, in close contact with and supporting the liquid crystal display module, and preventing deformation of the plastic cover lens, and a rear cover assembled at the rear of the panel-front.
1 . A display for a vehicle, comprising:
a plastic cover lens including a lens, a front film disposed on a front surface of the lens, and a rear film disposed on a rear surface of the lens;
a liquid crystal display (LCD) module disposed at a rear of the plastic cover lens;
an optical bonding layer disposed between the plastic cover lens and the LCD module, the optical bonding layer comprising a super retardation film (SRF) and an optically clear adhesive (OCA) disposed between and in direct contact with the rear film and the SRF;
a panel-front disposed at a rear of the plastic cover lens, in contact with and supporting the LCD module, and configured to prevent deformation of the plastic cover lens; and
a rear cover disposed at a rear of the panel-front,
wherein the rear film of the plastic cover lens includes a black masking layer printed on the rear surface of the lens excluding an active area corresponding to a position of the LCD module, and
wherein the OCA is in direct contact with a portion of the black masking layer adjoining the active area.
2 . The display of claim 1 , wherein the front film includes an anti-reflection (AR) coating layer and an anti-fingerprint (AF) coating layer formed at a front surface of the plastic cover lens via vacuum deposition.
3 . The display of claim 1 , wherein the plastic cover lens includes the front film and the rear film pre-molded in a shape of the plastic cover lens and is formed via insert mold labeling (IML).
4 . The display of claim 3 , wherein the plastic cover lens is formed such that a residual stress resulted from injection is minimized as the front film is disposed in an upper core of a mold and the rear film is disposed in a lower core of the mold and are pressurized to simultaneously perform injection-compression molding (ICM) during in-mold molding.
5 . The display of claim 1 , wherein the plastic cover lens includes a first area disposed on a side of a driver, a second area disposed on an opposite side of the first area, and a bent portion disposed between the first area and the second area.
6 . The display of claim 5 , wherein a first radius of curvature of the plastic cover lens is applied such that a radius of curvature of the bent portion is greater than a radius of curvature of the first area and a radius of curvature of the second area is greater than the radius of curvature of the bent portion.
7 . The display of claim 6 , wherein the plastic cover lens is formed in a shape having a 3 D curvature as the first radius of curvature is applied to the plastic cover lens in a horizontal direction, a second radius of curvature is applied to the plastic cover lens in a vertical direction for the plastic cover lens to become a concave lens, and a third radius of curvature is applied to a corner of the plastic cover lens.
8 . The display of claim 7 , wherein the corner of the plastic cover lens is formed to be rounded with a radius in a range from 2 mm to 3 mm.
9 . The display of claim 1 , further comprising a carrier-bezel mechanically coupled to an edge of the plastic cover lens to firmly maintain a shape of the plastic cover lens.
10 . The display of claim 9 , further comprising an adhesive tape adhered to at least a portion of the rear surface of the plastic cover lens to couple the plastic cover lens and the carrier-bezel to each other.
