A display device is provided. The display device includes a display panel including a plurality of pixels, at least one flexible circuit board connected to one side of the display panel and including a first portion and a second portion around the first portion, a source driving chip on the first portion, and a plurality of adhesion patterns on the second portion and extending in a set or predetermined direction.

Display device

A backlight unit includes a light source unit having a light source configured to emit a first light, a quantum dot sheet configured to emit a second light having a different color from the first light, a light guide plate configured to guide a light exiting from the light source unit or the quantum dot sheet, and an optical member including a prism sheet and configured to control the light exiting from the light guide plate. The quantum dot sheet includes a polymer resin and a plurality of first and second quantum dots, which are dispersed in the polymer resin. The second light is a white light obtained by mixing a red light, green light, and a blue light, and the second light has a concordance rate with an Adobe RGB color space which is no less than by about 99.9%.

Backlight unit and display apparatus having the same

A backlight unit includes a light source that emits light and a light guide plate disposed adjacent to the light source. The light guide plate includes an incident surface to which light is incident, an exit surface from which light incident through the incident surface exits, a reflection surface facing the exit surface to reflect the incident light, and a plurality of lenticular protrusions disposed on the exit surface. The reflection surface includes an inclined surface proximal to the incident surface and inclined with respect to the exit surface.

A display device capable of accurately sensing object presence at lower power consumption is presented, as well as a method of driving the display device. The display device includes a sensing circuit that detects the presence of an object by sensing radiation, and a radiation source array that provides radiation to the sensing circuit. First signals are provided to the scan lines of the sensing circuit, sequentially activating the sensors during a frame period. Second signals are provided to a radiation source array to selectively activate different portions of the radiation source array. The first and second signals are synchronized in their timing such that the portion of the radiation source array that supplies radiation to the activated sensors are turned on.

Energy-efficient display apparatus with object-sensing capability

A backlight unit includes a light guide plate and a light source unit. The light guide plate includes an exit surface which has a polygonal shape, a lower surface which faces the exit surface, and side surfaces which connect the exit surface and the lower surface. The light guide plate guides a light such that that light exits from the exit surface. The light source unit includes a plurality of light sources which provide the light to the light guide plate. The light guide plate includes a protrusion which protrudes from an end of the lower surface in a direction opposite to the exit surface. The protrusion includes a first inclination surface which is connected to one of the side surfaces, and a second inclination surface which connects the first inclination surface and the lower surface to each other.

An optical sheet includes a light-passing base sheet, a plurality of light-passing first patterns formed on a front major surface of the base sheet, and a plurality of light-passing second patterns formed on a rear major surface of the base sheet. The first patterns protrude from the front surface of the base sheet, a top portion of each of the second patterns makes contact with the rear surface of the second patterns while a larger lower surface of each of the second patterns is exposed to serve as a light receiving surface. Voids having relatively low refractive indices are formed between the light-passing second patterns. The optical sheet employs just one base sheet in one embodiment, thereby reducing a manufacturing cost of the optical sheet.

A diffusion plate includes a base having a top surface and a bottom surface and a plurality of parallel convex ridges integrally formed on the top surface of the base while extending in one direction. Each convex ridge has a cross section shaped as a portion of an ellipse. The display apparatus includes a display panel, a light source and the diffusion plate.

Diffusion plate and display apparatus having the same

A three-dimensional ('3D') image display device includes a backlight unit. The backlight unit includes a light guide part including a plurality of light guide units. Each of the light guide units includes a light guide plate including a light emission surface through which supplied light is emitted, a bottom surface which faces the light emission surface, and side surfaces which connect the light emission surface to the bottom surface, a plurality of light sources which emit light toward at least one of the side surfaces, and a band pass filter between the side surface to which the light is emitted and the light sources.
