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: The present disclosure provides a display panel, including: a first base substrate; a color conversion layer; a light-emitting device layer; and a liquid crystal layer. The liquid crystal layer includes a first optical path adjustment portion and a second optical path adjustment portion spaced apart from each other. Orthographic projections of the first optical path adjustment portion and a light-emitting device on the first base substrate at least partially overlaps with each other, and orthographic projections of the second optical path adjustment portion and the light-emitting device on the first base substrate are spaced apart from each other. In response to the second optical path adjustment portion being in a first state, in light emitted by the light-emitting device, light incident to the second optical path adjustment portion through the first optical path adjustment portion is refracted, or is scattered for at least once.
