  • Patent number: 10955602
    Abstract: The present disclosure provides a reflective polarizer module characterized by comprising: a first light collecting sheet including a first structuring pattern having a first unit light collector, the cross-sectional area of which is reduced progressively upward, which is disposed continuously in a repetitive manner, and collecting a light transmitted from below; a reflective polarizer sheet disposed in a stacked configuration on the top of the first light collecting sheet, and selectively transmitting the light by having a plurality of stacked layers having mutually different refractive indices; and a light recycling improving sheet disposed at the bottom of the reflective polarizer sheet, and randomly changing the polarized direction of the light which is not transmitted through the reflective polarizer sheet but is reflected downward.

  • Patent number: 10690839
    Abstract: The present invention provides a reflective polarizing module for enabling bending reduction, comprising: a reflective polarizing sheet having a cooling surface in which a plurality of stacks having different refractive indices from each other are laminated to selectively transmit light and which is cooled by being in contact with a separate cooling roll in a heated state, and an outer exposed surface which is placed in a stacked form on an upper portion of the cooling surface and is exposed to air to thereby slowly cool, wherein the reflective polarizing sheet has a shrinkage rate of the cooling surface by means of a temperature rise which is relatively higher than the shrinkage rate of the outer exposed surface; and an adhesive layer which is provided to at least any one of the cooling surface or the outer exposed layer to thereby bond a separate optical module and the reflective polarizing sheet, and reduce shrinkage and bending of the reflective polarizing sheet according to a temperature rise due to a sh

  • Patent number: 10506707
    Abstract: A flexible display device including; a base film; a display sheet formed over the base film; and a structural pattern formed below the base film for moving a neutral plane with respect to a bending stress applied to the display sheet to a layer having relatively low rupture point among the layers consisting of the display sheet. The neutral plane is moved to a layer having a relative low rupture point in a flexible display device by forming the structural patterns so that the bending stress applying to the layer having a relative low rupture point can be minimized.

  • Patent number: 10302843
    Abstract: Provided is a light concentrating module capable of reducing bending, comprising: a reflective polarization sheet layered with a plurality of stacks having different refractive indexes, so as to selectively transmit light, and having both sides of which the contraction rates are different; and a first light concentrating sheet having a first structural pattern in which first unit light concentrating bodies, of which cross-sectional areas gradually decrease towards an upper part thereof, are successively repeated, wherein the first unit light concentrating bodies are attached to one surface of the reflective polarization sheet, thereby reducing the contracting and bending of the reflective polarization sheet according to a rise in the temperature, caused by a difference between the contraction rate of the first light concentrating sheet and the contraction rate of one surface of the reflective polarization sheet.
