    Abstract: Embodiments of the present disclosure provide a display panel and a drive method thereof, and a display device. The display panel includes a plurality of sets of pixel columns and a plurality of drive circuits. Each of the sets of pixel columns includes a plurality of subpixel columns. The plurality of drive circuits correspond to the plurality of sets of pixel columns respectively. Each of the drive circuits is further configured to send, to an adjacent drive circuit, a source data signal for the subpixel column in the set of pixel columns of the drive circuit, and/or receive, from the adjacent drive circuit, a source data signal for the subpixel column in the set of pixel columns of the adjacent drive circuit and generate a data signal for driving the subpixel column in the set of pixel columns of the drive circuit, based on the received source data signal.

    Abstract: The disclosure provides a liquid crystal display panel and a display apparatus. The liquid crystal display panel of the disclosure includes: first and second substrates assembled to form a cell, a plurality of main spacers therebetween, and an auxiliary spacer around at least a portion of the main spacers. Height of the auxiliary spacer is greater than or equal to that of the main spacer. The display panel further includes: pillows on side of the first substrate close to the second substrate and each abutting against a corresponding main spacer. An orthographic projection of the main spacer on the first substrate falls within an orthographic projection of the pillow on the first substrate, and an orthographic projection of the auxiliary spacer on the first substrate does not overlap with the orthographic projection of the pillow on the first substrate.

    Abstract: A display panel includes: a base; a pixel defining layer disposed on a side of the base; a plurality of light-emitting devices disposed on a side of the base; and at least one connection portion disposed on a side of the pixel defining layer away from the base. The pixel defining layer has a plurality of first openings. At least a portion of each light-emitting device is located in a first opening. An orthogonal projection of a connection portion on the base is located within an orthogonal projection of the pixel defining layer on the base. A surface of the connection portion away from the base has a plurality of protrusions, and the connection portion is configured to diffusely reflect external ambient light incident into the display panel.

    Abstract: Provided is an array substrate. The array substrate includes: a base substrate, and a plurality of gate lines, a plurality of data lines, a plurality of sub-pixels and a plurality of touch signal lines disposed on the base substrate. The data lines have a plurality of first extending parts and a plurality of second extending parts which are in an alternating arrangement. When the array substrate is used to prepare a liquid crystal display panel and the liquid crystal display panel is displaying, in each column of the sub-pixels, the voltage polarities of the two adjacent sub-pixels which respectively belong to two adjacent first pixel regions are opposite.
