Abstract: An adjustable clamping device is provided. The adjustable clamping device includes: a clamping component, configured as a removable clamping object; and a support member, one end of which is movably connected to the clamping component. The support member has a first state in which angle support is formed with the clamping component and a second state in which the clamping component is attached, and the support member is rotated, so that the support member switches between the first state and the second state. According to the adjustable clamping device, angle support may be selectively formed with the clamping component by using the support member, thereby effectively solving a problem that an angle of an existing book clamping device cannot be adjusted.

Abstract: This application provides a display panel and an electronic device. A display region of the display panel is divided into at least two pixel regions. The pixel region includes at least two subpixels. The display region includes a first display region and a second display region. Subpixel density of the first display region is less than that of the second display region. In the first display region, at least some adjacent pixel regions have different structures. By changing structures of at least some pixel regions in the first display region, an arrangement rule of structures in pixel regions in the first display region is changed to some extent, and form a long-period diffraction grating or an aperiodic diffraction grating, so that a diffraction phenomenon caused by light passing through the display panel can be mitigated.

Abstract: This application provides a display assembly and an electronic device. The display assembly includes a display screen and a support member. The support member is fastened to a non-display side of the display screen. A first metal plate is disposed facing a first non-bending region. A second metal plate is disposed facing a bending region. A third metal plate is disposed facing a second non-bending region. The second metal plate is capable of being bent. At least two first elongated through hole groups of the second metal plate are arranged in a first direction. Each first elongated through hole of each first elongated through hole group extends in the first direction. A plurality of first elongated through holes in a same first elongated through hole group are arranged at intervals in a second direction. In the first direction, a sum of lengths of a first end part and a second end part of the first elongated through hole is less than a length of the middle part of the first elongated through hole.

Abstract: This application provides a support, a display assembly, and an electronic device. The support includes a hard plate layer. At least one gap is disposed on a part that is of the hard plate layer and that corresponds to a bending area. A flexible strip is disposed in each gap. A length direction of the flexible strip is the same as an extension direction of the gap, so that when the display is disposed on the support. There is also a support structure at a position corresponding to the gap of the hard plate layer on a flexible display, to avoid a failure problem such as a black spot that occurs because the display is squeezed at the position corresponding to the gap of the hard plate layer, and improve reliability of the display assembly.
