The present embodiment relates to a DC-DC converter including: a housing; a plurality of electronic components disposed inside the housing; and a flow path disposed on a lower plate of the housing. The flow path includes an expanding portion. The horizontal width of the expanding portion is greater than the horizontal width of a flow path on the front end of the expanding portion, and the vertical width of the expanding portion is less than the vertical width of the flow path on the front end of the expanding portion. The differential between the part wherein the surface area of the vertical cross section of the flow path is the biggest and the part wherein the surface area of the vertical cross section of the flow path is the smallest is 10% or less.

The disclosure provides a back film structure, a method for manufacturing the back film structure, a display panel and a display device. The back film structure is divided into a bending region and a non-bending region. The back film structure includes a thin film layer and a barrier structure on a side of the thin film layer. An orthographic projection of the barrier structure on the thin film layer at least overlaps an orthographic projection of a boundary line between the bending region and the non-bending region on the thin film layer.

A multifunctional base includes a flexible member and a base connected to an end of the flexible member. The base includes a rigid shell, a connecting edge extends along a periphery of the rigid shell, the flexible member is connected to the base via the connecting edge, and the connecting edge is made of flexible material. A connecting structure and an electronic device are also provided.

The present disclosure relates to a method for fabricating a rear cover glass and a flexible display device including a first body, a second body configured to be movable relative to the first body, a flexible display disposed on a front surface of the first body and a rear surface of the second body and configured such that a size of an area exposed to the front surface of the first body and a size of an area exposed to the rear surface of the second body vary as the first body and the second body are moved relative to each other, and a rear cover glass mounted on the second body and disposed to cover at least a part of the rear surface of the second body.

A receiver or transmitter designed for a broad range of frequencies requires a pre-select filter for incoming signals or a post-select filter for outgoing signals to minimize spurious signal responses. In conventional receivers, several discrete RF filters are used and a switched filter bank is created utilizing a large amount of space. A filter bank comprising a plurality of stacked shielded filters would enable different filter technologies and topologies to be used together, as other passive and active circuits may be combined into the one surface mountable component in order to save on PCB space.

A method of fixing a flexible printed circuit (FPC) and a mobile terminal are provided. The mobile terminal includes: a rear cover; a first FPC fixedly connected to the rear cover; a front housing provided with a battery accommodation compartment; in case that a battery is installed in the battery accommodation compartment, there is a gap between the battery and the first FPC.

The present invention discloses an electronic device and a cable organizing assembly. The electronic device includes a main structure with a body and the cable organizing assembly. The body has a penetration hole passing through the body and extends from a bottom surface to form a wall having a notch. The cable organizing assembly includes a cable fastening member fixed at the wall and correspondingly sealing the notch. The cable fastening member includes multiple cable grooves for fastening at least one cable. The central axis of each cable groove is not parallel to the central axis of the penetration hole. Cables pass through the penetration hole from one side of a top surface, become bent, and are fixed on one side of the bottom surface of the body by the cable organizing assembly. Thus, a liquid from the exterior is unlikely to enter along the cables into the interior.

Disclosed is a modular housing for drivers used for LED lamps. The housing includes connectors for AC in from a power source, DC out to the lamps, and also has connectors allowing for control lines to be received from a control box. The housing includes an arrangement for creating two opposite stacks of drivers. The fronts of the drivers are cooled by circulating air through the space between the stacks, and heat is also dissipated through the side walls of the housing, which acts as a heat sink. The number and specifications of the drivers in the housing are configured such that every module is able to serve a number of LED lamps.
