Display device and display substrate thereof

The invention provides a display device and a display substrate thereof. The display substrate comprises a display area, a porose area, and a partition area between the display area and the porose area. The partition area is provided with at least one partition ring surrounding the porose area, and is used for partitioning an organic light-emitting material layer. The partition ring comprises at least a support portion and a partition portion. The partition portion is provided with a tensile stress layer used for applying tensile stress to the partition portion. When the organic light-emittingmaterial layer is vapor-deposited, partial section of the partition portion in the partition ring is suspended. The partitioning effect on the organic light-emitting material layer is good, and external water and oxygen can be prevented from entering the display area from the opening. In addition, the partition portion can automatically block the organic light-emitting material layer. The use oflaser burning to remove the organic light-emitting material layer around the porose area is avoided. A hot process is omitted. The spacing between the porose area and the display area is shortened. The border of the porose area is reduced. Third, the tensile stress layer can apply tensile stress to the partition portion to prevent the suspended partition portion from collapsing and falling off. The partitioning performance of the partition portion is reliable.

The invention discloses a multi-target measurement and control communication antenna array optical fiber closed-loop calibration method, and aims to solve the problems of multiple antenna error calibration test parameters, inconsistency of receiving channels including antenna unit mutual coupling and large test quantity. The method provided by the technical scheme of the invention comprises the steps that a calibration signal generation unit generates receiving and transmitting calibration baseband signals based on a starting instruction; the receiving calibration baseband signal is subjectedto up-conversion to a radio frequency through the calibration frequency conversion unit, is transmitted to optical transmission equipment, is transmitted to the optical receiving/transmitting module of an antenna subarray through an optical fiber, is coupled to each receiving channel, and is transmitted to an amplitude-phase consistency measurement unit through the optical fiber after being processed, so that closed-loop calibration of receiving channels is realized; the transmitting calibration baseband signal is output to a receiving/transmitting calibration switch network through a switch network and a coupler and transmitted to rear-end optical transmission equipment; and the transmitting calibration baseband signal is obtained through down conversion and transmitted to the amplitude-phase consistency measurement unit, and closed-loop calibration of transmitting channels is achieved.

Complex three-dimensional multi-layer structure and manufacturing method thereof

The present invention relates to a 3-dimensional complex multilayer structure. The 3-dimensional complex multilayer structure includes a first pattern and a second pattern having different thicknesses formed on one or both surfaces of a plate. The first pattern is selected from the group consisting of parallel lines, parallel curves, parallel zigzag lines, and combinations thereof which do not meet each other. The second pattern is not parallel to the first pattern and is selected from the group consisting of parallel lines, parallel curves, parallel zigzag lines, and combinations thereof which do not meet each other. The interfaces between the first pattern and the second pattern form figures selected from the group consisting of polygons, circles, ellipses, and combinations thereof. The figures are repetitively formed on one or both surfaces of the plate. The 3-dimensional complex multilayer structure includes different complex patterns, whereas a conventional device has a kind of simple pattern. The 3-dimensional complex multilayer structure of the present invention can be manufactured by a simple process. Therefore, the 3-dimensional complex multilayer structure of the present invention can find application in various fields, including optical components for displays (e.g., light guide plates, diffusion plates, prisms, and color filters), next generation displays and display devices (e.g., TFTs, OTFTs, oxide TFTs, flexible displays, and transparent displays), next generation 3-dimensional semiconductors, dry adhesion based on the use of fine ciliary structures, micro/nano piezoelectric devices, lighting optical components, and biocell/virus research using micropatterns.
