Abstract:
PURPOSE: A flexible substrate for a display panel and a method for manufacturing the same are provided to secure the reduction of thermal expansion through a first film and improve the surface toughness through a second film. CONSTITUTION: A flexible substrate for a display panel comprises: a first film which includes a glass cloth(100) recessed in a first heat-resistant resin(110); a second film(200) which is made of a second heat-resistant resin and includes a laminate on at least one surface of the first film; and an intermediate material(120) which is applied onto the upper portion of the first film and bonds the first film with the second film.
Abstract:
The present invention relates to a composite sheet which comprises a matrix and a reinforcement impregnated in the matrix, wherein the matrix comprises a polysiloxane-polycarbonate copolymer, and the refractive index difference between the matrix and the reinforcement is less than 0.01, and to a display device comprising the composite sheet.
Abstract:
The present invention relates to a battery cover including a matrix and a reinforcing member inserted on the matrix, and a mobile terminal thereof. The reinforcing member includes a fabric composite formed by fabric with an aspect ratio between 50 × L and 250 × L, wherein the L is the millimeter unit conversion value of the length of the mobile device in which the battery cover will be used.
Abstract:
The present invention relates to a composite sheet which comprises: a matrix and a stiffening member impregnated in the matrix and has a surface roughness (Rt) of 1200 nm or less whereby the matrix includes a cured material of a composition containing a polyfunctional (meth)acrylate monomer or an oligomer thereof; to a method to manufacture the same; and to a flexible display device comprising the same.
Abstract:
The present invention relates to a manufacturing method and an apparatus of a composite film, which is characterized by comprising a step of squeezing a matrix impregnated body in which a reinforcing material is impregnated and hardening the matrix impregnated body and using a squeezing member disposed in an oblique direction to a moving direction of the matrix impregnated body in which the reinforcing material is impregnated, a composite film using the same, and a flexible substrate and a display device using the same.
Abstract:
An optical film of the present invention comprises a matrix resin and a reinforcing material impregnated in the matrix resin, wherein the reinforcing material includes a first direction glass cloth on which a plurality of glass yarns is disposed unidirectional on the same plane. The optical film can improve surface illumination because warp thread and weft does not intersect and can increase the efficiency of the process and improve productivity because the optical film does not undergo the process of removing an air gap of an orthogonal portion which is formed during the weaving.
Abstract:
PURPOSE: A flexible substrate for a display panel is provided to prevent the light leakage phenomenon occurring on a bonding surface through a thermal expansion coefficient of a resin and a metal mask. CONSTITUTION: A flexible substrate(100) for a display panel is made of a metallic material and comprises: a metal mask(110) in which plural openings are formed in grid pattern; and a heat-resistant resin(120) including an inorganic particle metal mask recesses, wherein the inorganic particle filler has the particles which are less than 150nm and ceramic powers having thermal expansion coefficient lower than 8ppm.
Abstract:
The present invention relates to a fiber laminate, a widow sheet and a flexible display device including the same. The fiber laminate includes: a plurality of single yarns; a first fiber substrate including a plurality of second single yarns crossed by the first single yarns and a first air gap formed by crossed the first single yarns and the second single yarns; and a second fiber substrate including a plurality of third single yarns, a plurality of fourth single yarns crossed by the third single yearns, and a second air gap. The first fiber substrate is arranged on the second fiber substrate to prevent the first air gap from being overlapped by the second air gap. A final air gap of the fiber laminate that penetrates the first air gap and the second air gap has an average area of 0.1 mm^2 or less.
