According to an embodiment of the disclosure, a housing of an electronic device may include a first surface including a first portion having an irregularity formed thereon and a second portion spaced apart from the first portion and having an irregularity formed thereon. The irregularities formed on the first surface may be formed by etching. A maximum height of the irregularity formed on the first portion may be different from a maximum height of the irregularity formed on the second portion. The maximum height of irregularities formed on the first surface may gradually increase or decrease from the first portion to the second portion.

Electronic device including housing and method for manufacturing the same

According to various embodiments of the disclosure, an electronic device may include: a housing, a processor disposed inside the housing, the housing may include a metal member comprising a metal and including a first convex and concave pattern formed in a shape corresponding to a shape of a second convex and concave pattern formed on a jig, wherein the jig is formed for use in electro chemical machining (ECM), and the first convex and concave pattern may have at least a portion formed at a substantially uniform pitch and a substantially uniform height.

Electronic device including housing

A display apparatus includes a light source which generates a first light, a display module which displays an image, a light guide plate disposed under the display module, and an optical filter disposed under the light guide plate to face the display module. The optical filter includes a filter layer which transmits a portion of the first light from the light guide plate and reflects a remaining portion of the first light except for the portion and an absorbing layer disposed under the filter layer to absorb the first light transmitted thereto through the filter layer. As an incident angle of the first light incident to the filter layer with respect to a normal line of an upper surface of the filter layer increases, an overlapping bandwidth between a reflection wavelength bandwidth of the filter layer and a wavelength bandwidth of the first light increases.

Display apparatus

A display apparatus includes a display module including a light conversion member including a plurality of quantum dots, a backlight unit providing a first light to the display module, and an optical filter disposed between the display module and the backlight unit. The optical filter includes a transmission filter layer transmitting a light in the first wavelength range and a second wavelength range, reflecting a light in a third wavelength range, and having a first effective refractive index and a viewing angle control layer disposed between the transmission filter layer and the display module to couple the transmission filter layer and the display module and having a second effective refractive index equal to or smaller than the first effective refractive index.

A light emitting device includes a light emitting chip which generates a first light having a first color, a first cavity layer disposed on the light emitting chip and which generates a second light having a second color and has a first refractive index, a second cavity layer disposed on the first cavity layer and which generates a third light having a third color and has a second refractive index, a first half mirror layer disposed between the first cavity layer and the light emitting chip and which reflects at least a portion of the second light, a second half mirror layer disposed between the first cavity layer and the second cavity layer and which reflects at least a portion of the third light, and a third half mirror layer disposed on the second cavity layer and which transmits the first light.

Light emitting device

A backlight unit includes a printed circuit board; a light source on the printed circuit board; a light guide plate that receives light emitted from the light source on one surface and directs light outwards through another surface; and a light blocking unit between the light source and the light guide plate. The light blocking unit may be spaced apart from the light guide plate.

Backlight unit

A display apparatus includes a backlight unit which generates light and provides the light to a display panel which displays an image with the light, a first polarizer disposed on the backlight unit, a third polarizer disposed on the first polarizer, a second polarizer disposed between the first polarizer and the third polarizer, a light transmittance layer which blocks or transmits the light therethrough to display the image, disposed between the first polarizer and the second polarizer, and a color conversion layer disposed between the second polarizer and the third polarizer, and including a color conversion material which converts a color of light transmitted through the light transmittance layer and the second polarizer. A polarizing axis of the third polarizer is different from a polarizing axis of the second polarizer.

A display device includes a display panel receiving light and displaying an image, a light guide plate guiding the light to the display panel, a printed circuit board disposed adjacent to one side of the light guide plate and including first and second areas alternately defined therein, light sources mounted on the printed circuit board to correspond to the first area and to supply the light to the light guide plate, a first barrier wall disposed on the printed circuit board and extending in a direction in which the light sources are arranged, and a second barrier wall facing the first barrier wall such that the light sources are disposed between the first and second barrier walls, the second barrier wall disposed on the printed circuit board, and extending in the direction.

Display device

A light emitting diode package includes a light emitting diode which emits a first light having a first color; a body member defining a planar part thereof on which the light emitting diode is mounted, and a side part thereof which is extended upward from the planar part, the planar and side parts defining an inner cavity in which the light emitting diode is disposed; and a filling member which fills the inner cavity and includes a base part in which a plurality of first phosphors is dispersed, the plurality of first phosphors absorbing a portion of the first light and generating a second light having a second color different from the first color. The body member which defines the planar and side parts thereof has a third color different color from the second color, and the body member having the third color absorbs light having the second color.

Light emitting diode package including color absorbing body member
