A sealing member for a light guide plate which has sufficient adhesive strength with a light guide member, suppresses embedding of the light guide member into concave-shaped portions, and provides high smoothness to a lid face of the concave-shaped portions, a light guide plate using the sealing member for a light guide plate, and a lighting device or a display device using the light guide plate are provided. A sealing member for a light guide plate, which is made of one layer or more to be laminated to a face having concave portions so as to seal at least any of gas, liquid and vacuum, which has a refractive index that is different from a refractive index of a light guide member, into insides of the concave portions of the light guide member having: an emission face in which light incident from an end face is bent and outgoes to a surface direction; and the plural concave portions on the emission face and/or an opposite face that faces the emission face, wherein a layer contact with the face having the concave portions of the sealing member for a light guide plate is made of a sealing layer which contains resin composed of a repeating unit derived from urethane (meth)acrylate having a saturated cycloaliphatic group.

An optical combiner lens includes a lens and a lightguide with a gap defined between the lens and the lightguide. Spacers are disposed in the gap to maintain the gap at a set height. A method of making the optical combiner lens and a wearable heads-up display including the optical combiner lens are disclosed.

The present disclosure provides a light-emitting module. The light-emitting module includes a light guide plate, a light source, and a brightness adjustment element. The light guide plate has a light incident surface, a front surface, and a back surface opposite the front surface. The light incident surface is located between the front surface and the back surface and is adjacent to the front surface and the back surface. The brightness adjustment element has a strip portion and at least one protruding portion. The strip portion has a first edge proximal to the light incident surface. The protruding portion is located on the first edge of the strip portion, and the protruding portion is aligned with the light source and extends away from the first edge.

A display apparatus includes a frame case to support four sides of a display panel. The frame case is formed by bending a bar-shaped member made of a metal into a rectangular ring shape. Opposite ends of the bar-shaped member facing each other are covered by a cover member, which prevents quality degradation of the appearance of the display.

A bio-sensor device, integrated with a display portion, includes a surface for touching by a body part, such as a finger. A light source, such as an array of LEDs, emit light through the surface so as to be reflected and partially absorbed by the body part An array of photodetectors detects light reflected back by the body part and generates signals corresponding to an image of the light reflection, which corresponds to the light absorption pattern in the body part. The light absorption pattern may correlate to a fingerprint, a blood vessel pattern, blood movement within the blood vessels, combinations thereof, or other biometric feature. A processor receives the signals from the photodetectors and analyzes the signals to determine a characteristic of the body part. The characteristic may be used to authenticate the user of the bio-sensor device by comparing the detected characteristic to a stored characteristic.

Provided is a refrigerator. The refrigerator includes a cabinet, a door configured to open and close the cabinet and having an opening, a panel assembly configured to shield the opening and including a see-through part, and a light provided further inward from the refrigerator than the panel assembly to illustrate a rear side of a door so that the inside of the refrigerator is visible through the see-through part. The wherein the panel assembly includes a transparent front panel defining a front surface thereof, a display disposed on a rear surface of the front panel, a light guide plate disposed to be spaced apart from the display, a backlight configured to emit light toward an end of the light guide plate, and a rear panel made of a transparent material, spaced apart from the front panel to define a heat insulation space in which the display, the light guide plate, and the backlight are accommodated. The light may emit light to a rear region of the light guide plate from the outside of the light guide plate and be disposed at an angle between a direction parallel to the light guide plate and a rear side crossing the light guide plate.

A display apparatus includes a display panel, a mold frame, and a plurality of cushioning sealing members in which: each cushioning sealing member includes a cushioning material, a first sealing material arranged on a surface of the cushioning material that faces the display panel, and a second sealing material arranged on a surface of the cushioning material that faces the mold frame; one end side in the longitudinal direction of the first sealing material extends to the mold frame so as to cover one end surface in the longitudinal direction of the cushioning material and one end surface in the longitudinal direction of the second sealing material; and one end portion in the longitudinal direction of the first sealing material is attached to the mold frame.

An optical member and a display device including the same. The optical member includes a light guide plate including a surface disposed on a plane defined by a first direction and a second direction crossing the first direction, a low refractive index pattern disposed on the surface of the light guide plate and including an opening for exposing the surface of the light guide plate, a wavelength conversion layer disposed on the low refractive index pattern, and a passivation layer disposed on the wavelength conversion layer and covering a side surface of the wavelength conversion layer and a side surface of the low refractive index pattern at least one side portion. The low refractive index pattern has a lower index of refraction than the light guide plate, and a ratio of an area occupied by the low refractive index pattern to an area of the surface of the light guide plate decreases in the first direction.

The present invention provides a clamper and a lighting fixture. An elastic layer for contacting a panel is disposed on a rotatable clamping portion. In addition to that, a distance from a lowest point of one end of the panel clamped by the rotatable clamping portion to a carrier plate supporting a polarizer at one side of the panel adjacent to a thin film transistor is greater than a thickness of the polarizer. Accordingly, the present invention prevents the panel and the polarizer at one side of the panel adjacent to the thin film transistor from being damaged from clamping.
