The invention discloses a display device and a manufacturing method thereof. The display device comprises a first flexible substrate layer, at least one buffer layer and a second flexible substrate layer. The second flexible substrate layer is formed on the buffer layer. The buffer layer is formed on the first flexible substrate layer. A patterned pattern is formed in a bending area of the bufferlayer, so that the first flexible substrate layer is attached to the second flexible substrate layer through the pattern.

The invention relates to an air inlet duct (60) for a nacelle (26) of an aircraft propulsion assembly (10). The duct (60) comprises an annular body (50) and an annular air inlet lip (40) comprising two coaxial annular walls (41, 42), respectively an inner wall (41) and an outer wall (42), the inner wall (41) defining part of an inner annular surface of the air inlet duct (60), and the outer wall (42) defining part of an outer annular surface of the air inlet duct (60). The air inlet duct (60) further comprises a control system (70) for axially translating the lip (40) relative to the body (50) from a first position in which the lip (40) is attached to the body (50) to a second position in which the lip (40) is axially spaced from the body (50). According to the invention, the duct (60) further comprises an annular row of grilles (90) fixed in translation to the lip (40), the annular row of grilles is configured to be housed within the body in the first position (50) and to extend from the body (50) in the second position such that an air flow (100) entering the air inlet duct (60) travels through the annular row of grilles.

The invention discloses an expressway expansion joint maintenance and reinforcement method which comprises the following steps: shooting an image of a damaged position of an expansion joint, and inputting the image and related parameters of the expansion joint into an analysis module; enabling the analysis module to callscorresponding maintenance parameters from a pre-stored maintenance parametercontrast data set by utilizing an analysis result after analysis; manufacturing a new expansion joint device according to the maintenance parameters; manufacturing a new fixed connection beam according to the maintenance parameters; dismounting the damaged expansion joint according to the maintenance parameters; fixing the fixedly-connected beams to the side walls of the mounting groove through anchor rods anchored to the two side walls of the mounting groove, and spraying the side walls and the bottom face of the mounting groove with concrete mortar; placing the expansion joint device in themounting groove and connecting the expansion joint device with the fixedly-connected beams; welding the connecting beam to the expansion joint supporting cross beam; and opening the traffic after thecover plate is repaired. The damage degree of the expansion joint is accurately judged according to the surface damage degree of the expansion joint, and the damaged expansion joint is replaced by theexpansion joint device manufactured in advance, so that the traffic influence is small, and the maintenance is convenient and fast.

A liquid crystal display panel and a preparation method therefor. The liquid crystal display panel comprises an array substrate (1), and a passivation layer (2), a planarization layer (3), a BPS material layer (4) and a first alignment layer (6) which sequentially stacked on the array substrate (1). A projection of the first alignment layer (6) on the BPS material layer (4) does not exceed an area of the BPS material layer (4). A plurality of grooves (41) is formed in the BPS material layer (4), and distributed along the inner side of the edge of the BPS material layer (4), and a sealant (5) is further formed on the BPS material layer (4), wherein the sealant (5) and the first alignment layer (6) are located at both sides of the plurality of grooves (41), respectively. The flow of the sealant (5) and the first alignment layer (6) can be blocked without preparing a retaining wall on the array substrate (1), and the situation that the sealant (5) and the first alignment layer (6) on the array substrate (1) exceed specifications in preparation is avoided.
