A pad for lamination includes a first pad which applies a first pressure to a first area of a display panel, and a second pad which is at least partially surrounded by the first pad in a plan view and which applies a second pressure to a second area different from the first area of the display panel. After the first pad fixes at least a portion of the first area of the display panel, the second pad stretches the second area of the display panel, such that a display device may be manufactured in which defects such as, for example, wrinkles of the display panel which may occur in a lamination process are minimized in quantity or reduced in size.

A display includes a first housing portion having graphic openings and a second housing portion spaced apart from the first housing portion. A first circuit board has LEDs and is disposed between the first and second housing portions. A first side wall and a second side wall define photon recycling cavities in a sequence wherein adjacent photon recycling cavities have a shared end wall an LED. The first side wall has a first angular surface and the second side wall has a second angular surface. The first angular surface and the second angular surface redirecting light from an associated LED of the plurality of LEDs so that light from the plurality of light emitting diode is indirectly communicated through the graphic openings after reflecting from the first angular surface and the second angular surface.

A light emitting apparatus is provided including a light emitting unit and a substrate in which the light emitting unit is disposed, wherein the light emitting unit generates light so that a main emission direction faces a horizontal direction parallel to the substrate.

A display device includes a substrate, a light-emitting element, and an encapsulation layer. The light-emitting element is disposed on the substrate, the encapsulation layer is disposed on the substrate and covers the light-emitting element, the light-emitting element has a first width in a first direction, the encapsulation layer has a top surface, the top surface includes a first trench, the first trench has a second width in the first direction, and the second width is greater than the first width.

The disclosure relates to the coating of a Light Emitting Diode (LED) lighting tube or the like to diffuse and reduce spotting along with glare that is produced by the individual LEDs within the unit. More specifically, the disclosure relates to coating intended for use with LED light sources and for allowing the transmission of radiation in the ultra-violet (UV) range of 315 to 400 mm (UV-A), 280-315 mm (UV-B) and 100-280 nm (UV-C) wavelengths, also suitable for visible lights LEDs at 400 to 700 nm wavelengths.

An electronic device includes a substrate, multiple light-emitting elements, and multiple barrier walls. The light-emitting elements are arranged in an array on the substrate. The barrier walls are disposed on the substrate and surround the light-emitting elements, wherein the barrier walls include multiple first barrier walls extending along a first direction and multiple second barrier walls extending along a second direction. In a top view of the electronic device, at least one of the multiple first barrier walls and at least one of the multiple second barrier walls surround one of the multiple light-emitting elements, and the terminal end of at least one of multiple first barrier walls is adjacent to and spaced apart by a distance from the terminal end of at least one of the multiple second barrier walls. The electronic device provided herein may possess relatively good display quality and/or relatively low manufacturing costs.

The present invention relates to the technical field of LED display devices, in particular to a latch assembly, an LED display screen cabinet, and an LED display screen. The latch assembly is configured to assemble two connected pieces into a single unit and includes a connecting base, a locking housing, a locking rod, and a handle. A stroke groove is formed on a side wall of the locking housing, and a first limiting groove and a second limiting groove, which are in communication with the stroke groove, are formed on a top wall of the locking housing; when the handle moves from the first limiting groove through the stroke groove to the second limiting groove, the locking rod is in a locked state; when the handle moves from the second limiting groove through the stroke groove to the first limiting groove, the locking rod is in an unlocked state.

A light-emitting module includes a housing and light-emitting units. The housing includes a bottom board. The light-emitting units are separately disposed on the bottom board and are arranged along a first direction and a second direction which intersects with the first direction to form an array. Each of the light-emitting units includes a first light-emitting element and two second light-emitting elements which respectively have upper surfaces away from the bottom board. The second light-emitting elements are disposed at two opposite sides of the first light-emitting element. A ratio of a length of any one of the second light-emitting elements parallel to the first direction to a length of the first light-emitting element parallel to the first direction ranges from 0.35 to 0.55. A sum of areas of the upper surfaces of the second light-emitting elements is not greater than an area of the upper surface of the first light-emitting element.

A light emitting apparatus including at least one light emitting device, a light transmissive layer disposed on the light emitting device, and a cover layer disposed on the light transmissive layer and partially covering an upper surface of the light transmissive layer.
