The present application relates to a spliced box and a spliced display screen. In the process of splicing and assembling a plurality of boxes, when there is a height difference between a second surface of a certain box and a second surface of other boxes, the first adjusting member at the box is adjusted to raise or lower the box so that the height of the second surface of the box is adjusted. As a result, the second surface of the box is on the same plane as the second surface of other boxes so that the display units on the second surface of the boxes are on the same plane.

The power module includes lead frames to be received in apertures formed on the PCB. The PCB configured with electronic components mounted thereon controls the electric motor. The inverter housing includes a front head and a cover. The cover in conjunction with the front head defines an enclosure for receiving the inverter. The inverter unit includes support elements to support the power module in a hanging configuration with respect to the PCB.

The present disclosure provides a sub-display panel assembly, including: a display substrate; a frame, including: a bottom plate having a support surface and a mounting surface arranged opposite to each other, where the support surface is configured to bear the display substrate; and a first circuit board on a side of the bottom plate away from of display substrate, including: a first circuit board body connected to the mounting surface of the bottom plate through an elastic component, where the elastic component is configured to support the first circuit board body and enable the first circuit board body to move relative to the bottom plate. An embodiment of the present disclosure further provides a tiled display apparatus.

An electronic device including a first base, a first conductive layer, an insulating layer, a first electronic element, a second base, and a second electronic element is provided. The first conductive layer is disposed on the first base. The insulating layer is disposed on the first conductive layer and has a first hole, wherein the first hole exposes at least a portion of the first conductive layer. The first electronic element is disposed on the first base. The second base is disposed between the insulating layer and the first electronic element, and has a second hole. The second electronic element is electrically connected to the first conductive layer. The first electronic element is electrically connected to the first conductive layer via the second hole and the first hole, and in a cross-sectional view of the electronic device, the second hole is different from the first hole in width.

A rollable digital blind comprises: a screen including a flexible display panel which displays an image and comprises a flexible material, and a flexible solar panel which is overlappingly disposed at one surface of the flexible display panel; a cylindrical-shaped roller which is rotated to wind the screen thereon or unwind the screen therefrom; a housing in which the roller is accommodated; a battery which is charged through the flexible solar panel; a drive unit which is supplied with power from the battery to rotate the roller; a composite photosensor which senses sunlight; and a control unit which, if the composite photosensor senses sunlight, controls the drive unit to unwind the screen and charge the battery through the solar panel. The rollable digital blind not only serves as a blind, but can also be used as a display for outputting an image.
