Abstract: A sounding device, a manufacturing method thereof and a display device are provided. The sounding device includes at least two sounding units. Each of the sounding units includes: a transparent structural layer, including a recess and a supporting member located around the recess; and a piezoelectric vibrating film covering the recess, a cavity is formed by the piezoelectric vibrating film and the supporting member. The piezoelectric vibrating film includes a base film covering the recess; and at least one piezoelectric structure located on a side of the cavity away from the transparent structural layer. Each of the at least one piezoelectric structure includes: a first electrode; a piezoelectric material layer located on a side of the first electrode away from the cavity; and a second electrode located on a side of the piezoelectric material layer away from the first electrode.

Abstract: A display panel, a display assembly, a display apparatus and a drive method therefor are disclosed. The display panel includes a first display area and at least one second display area. The first display area includes first sub-pixels, and the first sub-pixels are non-transparent sub-pixels. The at least one second display area includes second sub-pixels, and the second sub-pixels are transparent sub-pixels.

Abstract: The present invention provides a curved display panel and a manufacturing method thereof. The curved display panel comprises a first substrate and a second substrate which are aligned to form a cell, wherein a plurality of first spacers are arranged on the first substrate, a plurality of second spacer groups respectively corresponding to the first spacers are arranged on the second substrate, each of the second spacer groups includes at least one pair of second spacers, a gap is formed between each pair of second spacers, and each of the first spacers is engaged in the gap between the corresponding pair of second spacers so that accurate alignment between the first substrate and the second substrate is maintained.
