According to one embodiment, a display device comprises a display panel and a polarizing plate. The display panel comprises a display area, a non-display area surrounding the display area, and a light-shielding layer arranged in the display area and the non-display area. The polarizing plate is provided on a surface of the display panel, and including an end portion located in the non-display area. In this display device, the light-shielding layer opposite to the end portion of the polarizing plate is at least partially removed.

There is provided an information input and display device for use underwater, comprising a housing, a touch screen accommodated in the housing, electronic components to provide operation of the screen, wherein the touch screen has an upper flexible layer sensitive to a mechanical stimulus sufficient to depress the flexible layer at the stimulus location, and the housing has a window for access to the upper flexible layer and is sealed with a dielectric sealant such that at least a portion of the upper flexible layer remains uncovered with the dielectric sealant to allow contact with water.

A display device and its formation method are provided in the present disclosure. The display device includes a flexible display panel; a bending auxiliary layer fixed on a first surface of the flexible display panel; a support plate at a side of the bending auxiliary layer away from the flexible display panel; and an adhesive layer, between the bending auxiliary layer and the support plate, configured to fix the bending auxiliary layer to the support plate. A region where the bending auxiliary layer overlaps the support plate includes a first region and a second region. A sum of thicknesses of the bending auxiliary layer and the support plate in the first region is less than a sum of thicknesses of the bending auxiliary layer and the support plate in the second region. The adhesive layer is in the first region and not in the second region.

A display module includes a display panel, a first optical adhesive layer disposed on a side of a display surface of the display panel, a touch panel disposed on a side of the first optical adhesive layer away from the display panel, and at least one isolation film between the display panel and the touch panel. The display panel includes a display region and a peripheral region that is provided with at least one alignment mark. The touch panel includes a plurality of peripheral signal lines. An orthographic projection of the peripheral signal lines on a plane where the display panel is located at least partially overlaps with an orthographic projection of the at least one alignment mark on the plane.

An electronic device includes: a battery, a mainboard, and a housing. The battery is connected to the mainboard, the mainboard is provided with a first controller, the battery and the mainboard are installed in a cavity of the housing, and the housing includes a rear cover. The rear cover includes an electrochromic layer, the electrochromic layer is connected to the mainboard, the first controller is configured to control whether to power on the electrochromic layer, and a color displayed on the electrochromic layer when the electrochromic layer is powered on is different from a color displayed when the electrochromic layer is not powered on. The rear cover can change, by controlling a power-on and power-off status of the electrochromic layer, a color displayed on the electrochromic layer, and further change a color displayed on the rear cover, without changing a decorative film.

Described herein are liquid crystal (LC) assemblies that are dimmable and techniques for manufacturing LC assemblies. In some embodiments, an LC assembly includes a Guest-Host (GH) liquid crystal layer containing nematic liquid crystals, dye molecules, and a chiral dopant. The GH liquid crystal layer is located between a pair of substrates. The LC assembly is a film assembly, with each of the substrates including a flexible film and a conductive layer formed on the flexible film. The substrates are separated by spacers that define a cell gap. The GH liquid crystal layer is configured to transition the LC assembly between darkened and lightened states depending on the voltage across the conductive layers. The flexible films allow the LC assembly to conform to the surface of a window or other rigid surface to which the LC assembly is attached. The LC assembly can be attached via a liquid or film-based adhesive.
