Abstract: Embodiments of the present application provide a flexible display panel and a display apparatus, the flexible display panel includes a display layer and a layer group; the layer group includes at least one layer; and at least one layer of the layer group has a length in a first direction greater than a length of the display layer in the first direction. The layer group includes an upper layer group located above the display layer and a lower layer group located below the display layer; the upper layer group includes at least one layer; the lower layer group includes at least one layer; at least one layer of the upper layer group and/or the lower layer group has a length in the first direction greater than the length of the display layer in the first direction.

Abstract: A support unit is arranged on a non-light-emitting surface of the display panel. The support unit includes a support plate and an isolation layer. The support plate is located on a side of the display panel. The isolation layer is located on a side of the support plate away from the display panel, and includes at least one of a moisture-isolating layer or a heat-isolating layer.

Abstract: A polarizer, an electronic device and a preparation method for the polarizer are provided, the polarizer including: a base film, having a side surface and defining a first region and a second region surrounding the first region on the side surface; a linear polarizing film, arranged on the side surface of the base film and covering the second region; a transparent filler, arranged in a same layer with the linear polarizing film and covering the first region; and a retardation film, covering a side of the linear polarizing film and a side of the transparent filler away from the base film.

Abstract: A support plate, including at least one bendable area and a non-bendable area connected to the bendable area. The bendable area includes a first bendable zone and a second bendable zone located between the first bendable zone and the non-bendable area. The first bendable zone includes a first etching pattern, and the second bendable zone includes a second etching pattern. The flexural rigidity of the second bendable zone is greater than the flexural rigidity of the first bendable zone, and is less than the flexural rigidity of the non-bendable area. In the first bendable zone, the closer a region to the second bendable zone, the greater the flexural rigidity of the region.

Abstract: A signal transmission circuit board includes a main body and a first connecting unit connected with the main body. The first connecting unit includes a test pin area and an avoidance area adjacent to the test pin area, and the avoidance area is free of test pins.

Abstract: One or more embodiments of the present application relate to a flexible display panel and a display apparatus, the flexible display panel includes a display layer, an upper layer group located above the display layer, and a lower layer group located below the display layer. The upper layer group includes at least one layer. The lower layer group includes at least one layer. The at least one layer of the upper layer group and/or the at least one layer of the lower layer group comprises at least one target layer. In response to a trigger condition, a characteristic parameter of at least partial region of the at least one target layer in the upper layer group and/or the lower layer group switches between a first range and a second range, and a minimum value in the second range is greater than a maximum value in the first range.
