Abstract: A drive method for a display panel, and a display apparatus. The drive method includes: when current original gray-scale values corresponding to sub-pixels in the same region are the same in a plurality of continuous display frames, converting the current original gray-scale values into a first target gray-scale value and a second target gray-scale value; in a current display frame of the plurality of continuous display frames, controlling a data voltage corresponding to the first target gray-scale value to be input to a first sub-pixel unit in the region, and controlling a data voltage corresponding to the second target gray-scale value to be input to a second sub-pixel unit in the region, where each of the first sub-pixel unit and the second sub-pixel unit includes at least one sub-pixel.

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 light-emitting substrate includes a substrate, a first metal layer, a first insulating layer, a second metal layer and a conductive adhesive. A bonding region is proximate to a selected side edge of a first surface of the substrate. The first metal layer on the first surface includes first bonding electrodes. The first insulating layer is on the first metal layer, and a border thereof proximate to the edge is closer to the edge than a border of the first bonding electrodes facing the edge. The second metal layer includes second bonding electrodes. The conductive adhesive in the bonding region covers portions of the second bonding electrodes. A ratio of a dimension of an edge portion of the first insulating layer in a second direction to a dimension of a first bonding electrode in same direction is greater than or equal to ⅕ and less than or equal to ½.
