An optical fiber plate manufacturing apparatus using vibration, includes: an optical fiber supply unit configured to supply an optical fiber; an optical fiber cutting unit configured to cut the optical fiber, supplied from the optical fiber supply unit, to a preset size; an optical fiber storage case configured to collect and store optical fibers, cut to the preset size, in a predetermined direction; and an optical fiber arranging unit configured to arrange the optical fibers, stored in the optical fiber storage case, using vibration so as to minimize a gap between the optical fibers.

Optical fiber plate manufacturing apparatus and method using vibration

Disclosed are a curved display manufacturing apparatus, comprising: a curved surface suction mold comprising a panel seat surface having a curved shape corresponding to a curved shape of the curved display to be formed, and air sucking holes formed through the panel seat surface; an air sucking unit for sucking air through the air sucking holes; a main frame for supporting the curved surface suction mold, to space the curved surface suction mold from a bottom of the main frame; and a pressing roller unit for pressing a curvature maintaining member to maintain the display panel in a bent state while sliding along a curved surface of the display panel under a condition that the curvature maintaining member overlaps with the display panel, for pressed attachment of the curvature maintaining member to the display panel.

Curved display manufacturing device and curved display manufacturing method

A backlight unit of a curved display device to irradiate a curved display panel with light comprises: a light source configured to emit light to the display panel; and a back plate including a plurality of planar sections, each having a predetermined width, arranged in a circumferential direction of the display panel on a concentric circle, the center point of which coincides with the center point of a virtual circle defined by the curved display panel, the planar sections of the back plate being bent relative to each other into a curved form such that the light source is installed to the respective bent sections of the bent curved back plate.

Backlight unit comprising bent curve-shaped back plate, and curved display device using the same

A method of etching a display panel for manufacturing a curved display device comprises the steps of: applying a masking ink in a manner of immersing a non-etched portion of a display panel into an ink reservoir, which contains the masking ink, in order to protrude the non-etched portion from the display panel; curing the masking ink coated on the non-etched portion of the display panel; etching the display panel to reduce the thickness of the display panel by coating an etching liquid onto the display panel on which the masking ink is cured; and removing the masking ink from the etched display panel with a solvent, which dissolves the masking ink.
