A display panel and a display device are provided. At four corners of the display panel where a first inorganic layer and a second inorganic layer are attached, the display panel is defined with a through hole filled with a stress-buffering component. As a result, stresses on a bending area of the display panel are reduced by the stress-buffering component, and the display panel is prevented from breakage due to stress concentration.

Display panel and display device

A display device, and the display device includes a display panel is provided. The display panel includes a planar area, a first bending area, and a second bending area. The planar area includes a main display area and a peripheral area. The peripheral area includes a first peripheral area. The first peripheral area is located at a corner of the main display area, and the first peripheral area is located between the first bending area and the second bending area. A first alignment mark is provided in the first peripheral area.

Display device

A display panel and a display device are provided. The display panel includes a central portion having first sides and second sides alternately arranged, where each of the first sides extends in a direction away from the central portion to form a peripheral portion. The peripheral portion includes a third side and a fourth side respectively connected to both ends of a corresponding first side and extending to middle of the first side. The second side is located within a region defined by an extension line of a corresponding third side, an extension line of a corresponding fourth side, and two respective extension lines of two corresponding first sides.

A display panel and a manufacturing method thereof are provided. In the manufacturing method of the display panel, a corner-cutting area of a to-be-cut display panel is provided with a cutting groove. The cutting groove penetrates a buffer layer and extends into a flexible substrate. Furthermore, the cutting groove is provided with an inorganic encapsulation layer and a sacrificial layer. Therefore, when cutting the to-be-cut display panel along the cutting groove, cracks generated during a process can be reduced, thereby alleviating a problem of micro-cracks affecting a packaging effect of conventional display panels during a secondary cutting process.

Display panel with grooves and manufacturing method thereof

A display panel and a manufacturing method thereof are provided. The display panel includes a non-display area which is provided with a bending area. The bending area includes a substrate layer, a metal wiring layer, and a first planarization layer sequentially disposed. A groove is defined on a surface of the substrate layer away from the metal wiring layer, where a groove wall of the groove extends along a curved surface or a flat surface to a groove bottom of the groove to let an orthographic projection of the groove bottom of the groove on the substrate layer fall within an orthographic projection of an opening of the groove on the substrate layer, so that the metal wiring layer is located in a neutral layer or close to the neutral layer.

Display panel and manufacturing method thereof

The invention discloses a method for generating a row transposed architecture based on a two-dimensional FFT processor, comprising the following characteristic: the FFT processor includes an on-chip row transposition memory for storing an image row transposition result. When the size of the row transposition result exceeds the capacity of the on-chip memory, the first 2k data of a row of the two-dimensional array after row transformation is written into the on-chip row transposition memory, the remaining data is written into the off-chip SDRAM, and k is acquired through calculation according to the row transposition result and the capacity of the on-chip row transposition memory. The on-chip memory is divided into two memories A and B used for storing the row transposition partial result and temporarily storing data read from off-chip SDRAM. When data is read from the memory A or B column by column for FFT column transposition, SDRAM is accessed in a row burst manner and data is written into the empty memory A or B alternately, and finally SDRAM is empty through repetitive ping-pong switching between the memories A and B. The row transposed architecture is capable of substantially reducing cross-line accessing frequency of SDRAM and improving two-dimensional FFT execution speed.

A large mode field active optical fiber and manufacture method thereof is provided. The large mode field active optical fiber is formed by drawing a fiber core (), a quartz glass internal cladding (), a quartz glass outer cladding (), and a coating (). The quartz glass internal cladding (), the quartz glass outer cladding (), and the coating () are sequentially coated on the outer surface of the fiber core (). The fiber core () is formed by depositing, melting, and shrinking the tetrachlorosilane doped with rare earth ions in a quartz glass tube. The refractive index of the fiber core () is a graded refractive index, and the section parameter a thereof is 1&#x2266;&#x3b1;&#x2266;3. The appearance of the quartz glass inner cladding () is regular multi-prism shaped. The large mode field active optical fiber provides an approximate single mode output, increases the capacity of bearing the laser power for the active optical fiber, increases the quality of the light beam of the output laser, avoids the problem that there is a hollow ring in the output laser, increases the reliability of the high power fiber laser, increases the utilization efficiency of the raw materials, and reduces the manufacture cost.
