White light emitting device and display device using the same

Disclosed herein is a display panel capable of avoiding a wire grid polarizer (WGP) process requiring a high temperature process and preventing deformation of a film polarizer by replacing a WGP with a film polarizer and by separately filming a transparent electrode and an alignment layer, a display apparatus having the display panel and a method of manufacturing the display panel. The display panel comprises a quantum dot color filter layer configured to convert a color of light emitted from a light source, a common electrode spaced apart from the quantum dot color filter layer, and a film polarizer arranged between the quantum dot color filter layer and the common electrode, and configured to be laminated with the quantum dot color filter layer after being laminated with the common electrode.

Display panel and display apparatus having the same

The present disclosure relates to a display apparatus including a display panel, a light guide plate disposed in the rear of the display panel, and at least one light source package disposed on one side of the light guide plate to supply light. The light source package includes a light source generating light, a package housing disposed to be spaced apart from a circumference of the light source, an encapsulation member disposed between the light source and the package housing and having an accommodation space on one side thereof, and a cover glass disposed in the accommodation space to face a light exit surface of the light source and configured to be equal to or larger than an area of the light exit surface.

Display apparatus

A display device includes a light source to emit light, a light guide plate on which the light emitted from the light source is incident and which irradiates light through a first and a second surface of the light guide plate, a quantum dot sheet on which the light irradiated through the first surface of the light guide plate is incident and which irradiates blue light, green light and red light, a reflective sheet for reflecting the irradiated light to the light guide plate, and a light-converting material at an edge portion of the light guide plate, the quantum dot sheet and the reflective sheet, for converting the light into a yellow light, green light or red light. The light incident on the quantum dot sheet includes the light emitted from the light source and the yellow light, the green light or the red light.

Display device and backlight unit included therein

A display panel, including a light source configured to emit blue light; and a quantum dot color filter layer including: a red light converter including a red quantum dot particle configured to convert the blue light into red light, a green light converter including a green quantum dot particle configured to convert the blue light into green light, a light transmitting portion configured to transmit the blue light, and a white light generator including a first region and a second region, wherein the first region comprises a plurality of yellow quantum dot particles configured to convert the blue light into yellow light, wherein the second region transmits the blue light.

The display panel includes a light emitting device, three quantum dot converters including quantum dot particles and converting light of a first color emitted from the light emitting device to light of a different color and emitting the light of the different color, a transmission part transmitting light of the first color emitted from the light emitting device, and a transparent substrate disposed on one side of the three quantum dot converters and the transmission part. One of the three quantum dot converters emits a white light to the transparent substrate.

Display panel and display apparatus using the same

Disclosed is a display apparatus including a display panel, a light guiding plate disposed behind the display panel, a light source disposed to oppose a side of the light guiding plate, a dichroic filter that selectively transmits blue light disposed to cover a front side of a space between the light source and the side of the light guiding plate, and a black member disposed in front of the dichroic filter. Here, since light emitted forward from the light source toward the dichroic filter is generally absorbed by the black member or incident on the light guiding plate, the occurrence of bright parts caused by light leakage is suppressed.

Display apparatus including dichroic filter

The display assembly includes: a light source configured to emit light; a light guide plate disposed to receive light emitted from the light source on a lateral side; and a color transformer disposed proximate to an edge of the light guide plate, and configured to change a color of light incident to the color transformer.

Display assembly and display apparatus using the same

A liquid crystal display (LCD) includes a cover assembly; a liquid crystal panel; a light guide plate configured to guide light to the liquid crystal panel; a printed circuit board (PCB) to which the light guide plate is mounted; and a light emitting diode (LED) package which is mounted on the PCB and emits light to a lateral side of the light guide plate. The PCB includes a base substrate; a connecting hole which is formed in the base substrate to couple the base substrate to the cover assembly with a connecting member; an insulating layer which is coated on the base substrate while avoiding a head part of the connecting member; and a spacer tape which is provided on an upper side of the insulating layer so that the light guide plate is evenly mounted on the PCB.

Liquid crystal display and LED module thereof

A display apparatus includes: a display panel; and a backlight configured to supply light to the display panel, wherein the backlight includes a light source configured to emit light; and a light guide plate provided on a rear side of the display panel and configured to guide the light emitted by the light source toward to the display panel; and a plurality of optical sheets provided between the light guide plate and the display panel, an optical sheet of the plurality of optical sheets being attached to a front surface of the light guide plate.

Disclosed is a display apparatus having a liquid crystal panel to display images; a light source to supply light to the liquid crystal panel; and a printed circuit board having a light source embedding unit in which the light source is embedded, and a connector mounting unit at which a connector configured to connect to an outside circuit is mounted. The printed circuit board is bent such that the connector mounting unit may be positioned lower than or offset from the light source embedding unit. The printed circuit board may be bent such that the connector may not be protruded further upward than the height of an upper surface of the light source embedding unit, and thus the thickness of the display apparatus may be improved.

A display apparatus including a dichroic filter is provided. The display apparatus includes a display panel including a liquid crystal layer and a quantum dot color filter disposed on the liquid crystal layer; a light source configured to emit light; a light guide plate configured to guide the light emitted from the light source towards the display panel; and a dichroic filter provided on a first side the light guide plate that is opposite to a second side of the light guide plate on which the display panel is provided, the dichroic filter being configured to concentrate the light emitted from the light source.
