Abstract: Exemplary subpixel structures include a directional light-emitting diode structure characterized by a full-width-half-maximum (FWHM) of emitted light having a divergence angle of less than or about 10°. The subpixel structure further includes a lens positioned a first distance from the light-emitting diode structure, where the lens is shaped to focus the emitted light from the light-emitting diode structure. The subpixel structure still further includes a patterned light absorption barrier positioned a second distance from the lens. The patterned light absorption barrier defines an opening in the barrier, and the focal point of the light focused by the lens is positioned within the opening. The subpixels structures may be incorporated into a pixel structure, and pixel structures may be incorporated into a display that is free of a polarizer layer.

Abstract: The present disclosure is generally related to 3D imaging capable OLED displays. A light field display comprises an array of 3D light field pixels, each of which comprises an array of corrugated OLED pixels, a metasurface layer disposed adjacent to the array of 3D light field pixels, and a plurality of median layers disposed between the metasurface layer and the corrugated OLED pixels. Each of the corrugated OLED pixels comprises primary or non-primary color subpixels, and produces a different view of an image through the median layers to the metasurface to form a 3D image. The corrugated OLED pixels combined with a cavity effect reduce a divergence of emitted light to enable effective beam direction manipulation by the metasurface. The metasurface having a higher refractive index and a smaller filling factor enables the deflection and direction of the emitted light from the corrugated OLED pixels to be well controlled.

Abstract: The present invention is a pallet strapping device having a platform, a lower guiding strap portion, an upper guiding strap portion, a first frame portion, a second frame portion and a central guiding strap portion. By controlling a first guiding strap portion, a second guiding strap portion, and the central guiding strap portion that is moved to a retracted position, a first guiding strap circulation path can be formed. In addition, by controlling the first frame portion, the second frame portion and the central guiding strap portion that is moved to an extended position, a second guiding strap circulation path is formed. The present invention is capable of switching to different strapping paths corresponding to different pallets for strapping. Besides, it is quite convenient to conduct strapping tasks under the condition that the corresponding pallets is not needed to depart from the platform of the pallet strapping device.

Abstract: The present invention includes a housing, multiple conveyors, and a driving system. The conveyors are provided for a working object to be moved on the conveyors. The driving system has a horizontal moving portion and a vertical moving portion. As the horizontal moving portion moves from the second position toward the first position, when a first detector detects a rear edge of the working object, a controller is able to stop the horizontal moving portion and to set an actual pushing position. Then, it can reset that the horizontal only can move between the actual pushing position and the second position for shortening a moving time and a moving distance of the horizontal moving portion. So, this invention can shorten the horizontal moving time of the horizontal moving portion. It can shorten the vertical moving time. Plus, it can increase the total processing efficiency.

The chute has an upper chute portion and a lower chute portion. The movable working assembly which is in the storing space includes a horizontal movable portion, a vertical movable portion, a working device, and an operation linkage mechanism. When the vertical movable portion moves to the move-down position, the lower chute portion is separated from the upper chute portion. Then, the movable working assembly can be moved out for easy maintenance. So, it is quick and easy to repair any internal device or part inside the strapping machine. The repairer does not need to stoop or squat down for repairing it. In addition, it saves strength and time to move out the working device or related part.

Abstract: A cross-strapping device includes a base, a lateral strapping mechanism, and a longitudinal strapping mechanism. This base has a working surface. The lateral strapping mechanism has a lateral chute, a first strap supplying assembly, and a first sealing/cutting assembly. A first strap is guided by the lateral chute and is strapped around the object to finish a lateral strapping procedure. The longitudinal strapping mechanism has a longitudinal guider, a second strap supplying assembly, and a second sealing/sealing assembly. A second strap is guided by the longitudinal guider and be strapped around the object to finish a longitudinal strapping procedure. So, this object is placed on a fixed working surface without rotation. The lateral strapping procedure and the longitudinal strapping procedure are completed on the same working surface. Hence, both the lateral strapping procedure and the longitudinal strapping procedure can be done in only one machine. In addition, the turn table is not required.

Abstract: A device having a liftable strap supply reel includes a housing, a liftable mechanism and a pushing force generator. The liftable mechanism is pivoted on the housing and it has a first arm that is disposed with a rotatable strap supply reel. The liftable mechanism contains a home position, a critical position, and a lift-up position. When this lifting mechanism is positioned at the lift-up position, the pushing member generates a force to create a torque so that the strap supply reel stays at a height near a waist of a human. So, the strap supply reel can be lifted up to a height approximately near a waist of a human. It can be operated by one hand. In addition, it is convenient to repair or replace the strap.

Abstract: A strapping machine automatically adjusting the strap tension includes a sensor to interact with two sense members fixed on a subordinate wheel of an advance and retreat device, which consists of a main wheel and the subordinate wheel. The sensor and the sense members sense the advanced and the retreated rounds of the subordinate wheel when a strap is moved through a gap between the main wheel and the subordinate wheel.
