Abstract: A desktop stapler includes a base portion. A lever is pivotally coupled to the base portion at a pivot point. A gap is defined between the base portion and a distal end of the lever opposite the pivot point. A biasing member is coupled to the lever and biases the lever away from the base portion. A solenoid is operable with a first actuation to move the lever relative to the base portion to decrease the gap and with a second actuation to drive a staple from the lever. A controller is programmed to sequentially initiate the first actuation and the second actuation.

Abstract: This application discloses a display device. The display device includes a display module, a frame surrounding the sides of the display module, a backlight module stacked with the display module, and a backplane. The frame includes holes. The backplane includes a main plane, side walls, and protrusions. The main plane is located on a side of the backlight module away from the display module. The side walls extend from the edges of the main plane toward the display module and are perpendicular to the main plane. The protrusions are located on the side walls and each of the protrusions is embedded in a corresponding one of the holes of the frame.

Abstract: The present disclosure provides a display module and a backlight module. The display module includes a back plate, a light source disposed on the inner side of the back plate, and a heat pipe, wherein the back plate is provided with vertically bent walls bent inwards around thereof, and wherein one side of a portion of the heat pipe is configured to abut against the light source, and the other side thereof is configured to abut against the vertically bent walls of the back plate.

Abstract: The present disclosure provides a light guide plate, a backlight module assembly and a liquid crystal display device, which are of a liquid crystal display technical field. The light guide plate includes a plate body and a retaining wall. One surface of the plate body is a light-emitting surface of the light guide plate, and the retaining wall is an annular structure arranged along an edge of the plate body, and protrudes to the light-emitting surface. The plate body and the retaining wall together form a groove for receiving a display panel and an optical film. The present disclosure solves a problem of poor polarizer as a result that the plastic frame shrinks and presses the display panel at a low temperature.

Abstract: A backlight module is disclosed. The backlight module includes: a back plate; an LED light strip arranged on a side of the back plate and along an edge of the back plate; a plurality of heat pipes each of which is disposed on the back plate at the same side as the LED light strips; wherein one end of the heat pipe is respectively adapted to be connected with the LED light strip, and at least part structure of each heat pipe is arranged along a temperature gradient direction of heat on the back plate when the LED light strip is in working state. In the backlight module when the backlight module is dissipating heat, the overall temperature distribution is uniform and local overheating does not occur.

Abstract: Methods of forming metal matrix nanocomposites are provided. The methods include the steps of introducing a master metal matrix nanocomposite into a molten metal at a temperature above the melting temperature of the master metal matrix nanocomposite, allowing at least a portion of the master metal matrix nanocomposite to mix with the molten metal and, then, solidifying the molten metal to provide a second metal matrix nanocomposite.
