Abstract: Provided are a lighting device, a backlighting device, and a display device that comprise a radiation source such as LED and wavelength converting members comprising phosphors. In one embodiment, self-absorption within the devices is suppressed or reduced by placing a selective reflector between two wavelength converting members, and the wavelength converting member emitting light with longer peak wavelength is substantially isolated from the irradiation of another wavelength converting member emitting light with shorter peak wavelength. In other embodiments, the wavelength converting members are arranged in strip configuration; or in adjacent hexagons configuration.

Abstract: A display panel assembly includes a first substrate having an effective display region for displaying an image and a non-effective display region positioned at a peripheral region outside of the effective display region, a second substrate facing the first substrate, a sealing member disposed along a boundary between the effective display region and the non-effective display region between the first and second substrates, the sealing member including a thermosetting material, and an exothermic member interposed between the sealing member and the first substrate to generate heat for curing the sealing member.

Abstract: In an axial fan (1), equipped with a frame (13), a motor (2) and an impeller (3) whose hub (15) is rotationally driven by the motor (2) and where the hub (15) is cup-shaped, with an end wall (16) and an annular side wall (17) to partially contain the motor (2), the motor (2) protrudes from the hub (15) with its longitudinal end (23) which is supported and laterally surrounded by a crown (12) of the frame (13) and the crown (12) has an annular end strip (21) facing the hub (15) and laterally surrounding an annular end strip (22) of the hub (15) which faces the crown (12).

Abstract: A metering body for a chemical injection system comprises a free piston having a pair of mechanically-actuated poppet valves which may individually open to permit fluid to pass from one side of the free piston to the other. The free piston slides within a cylinder having cylinder heads at opposing ends. Input/output ports are provided in the cylinder heads. In a preferred embodiment, the poppet valves have actuators that extend beyond the opposing faces of the free piston. If one face of the piston moves to within a predetermined distance of a cylinder head, the actuator contacts the cylinder head and further movement of the piston causes the corresponding poppet valve to open, permitting fluid to flow through the piston. In this way, a fault-tolerant system may be implemented. If a power interruption or other failure of the controller occurs, the system will continue to supply fluid at the most recently selected flow rate.

Abstract: An organic light emitting device, which includes a first substrate, scan lines and data lines arranged on the first substrate, and at least an unit pixel comprising a R sub-pixel corresponding to a Red color, a G sub-pixel corresponding to a Green color, and a B sub-pixel corresponding to a Blue color positioned in a region on the first substrate defined by a crossing of the scan and data lines.

Abstract: A pump element includes a pump element housing defining a pump chamber having an inlet and an outlet, and at least a first movable element movable in the pump chamber between a first and a second position. During a movement of the first movable element in the direction from the first to the second position, a flow resistance of a flow path from the first movable element through the inlet is larger than a flow resistance of a flow path between the pump element housing and the first movable element. During a movement of the first movable element in the direction from the second position to the first position, a flow resistance of a flow path from the first movable element through the outlet is smaller than a flow resistance of the flow path between the pump element housing and the first movable element. Thus, during a reciprocating movement of the first movable element between the first and the second position, a net flow through the outlet takes place.
