摘要： An optical path structure, an optical path system, and a transfer method. The optical path structure includes a beam adjustment module configured to adjust a diameter of a laser beam and output a first beam; a beam shaping module configured to perform energy homogenization on the first beam to obtain a second beam; and a beam focusing module configured to focus the second beam and output a target light spot; the target light spot is used for irradiating a device substrate, so that a bonding material in the device substrate changes after being irradiated by the target light spot, and a target device is separated from a carrier substrate; where the bonding material is disposed between the target device and the carrier substrate.

摘要： A display panel, a manufacturing method of the display panel, and a display device including the display panel are provided. The display panel includes an insulating substrate; a first circuit at a first side of the insulating substrate; and a second circuit at a second side of the insulating substrate. The first side and the second side of the insulating substrate are opposite to each other in a first direction perpendicular to a display surface, and the first circuit and the second circuit on opposing sides of the insulating substrate are electrically connected by tapered through hole and tapered pad.

摘要： Provided are a display panel, a preparation method thereof, and a display apparatus. The display panel includes an array substrate and a color filter substrate aligned and combined into a cell. The color filter substrate includes a first base substrate and a plurality of color resist blocks arranged at intervals on the first base substrate. The array substrate includes a second base substrate and a plurality of pixel electrodes arranged at intervals on the second base substrate. The pixel electrodes are in one-to-one correspondence with the color resist blocks. The display panel includes a bending area and a non-bending area located at least on one side of the bending area. A density of the pixel electrodes in the bending area is less than that in the non-bending area, and a density of the color resist blocks in the bending area is less than that in the non-bending area.
