Abstract: A manufacturing method of a splicing display panel and the splicing display panel are provided. Front surfaces of backplates are encapsulated to form first encapsulation layers. Then, at least two backplates are fixed on a transparent substrate to make grooves be formed between lateral surfaces of two adjacent backplates and the transparent substrate. Next, second encapsulation layers are formed in the grooves to obtain an encapsulation semi-finished product. Finally, a third encapsulation layer is formed on a peripheral side of the encapsulation semi-finished product, thereby obtaining the splicing display panel. Technical problems that encapsulation of lateral surfaces of the display panel is difficult and seams of the splicing display panel are obvious can be solved.

Abstract: Provided are pyrimidine aromatic ring compounds. Specifically provided is a compound as represented by formula (II) or a pharmaceutically acceptable salt thereof.

Abstract: A driving method of an electronic paper display apparatus, including: inputting, by a controller, a first driving signal to a pixel electrode of a pixel driving circuit corresponding to a pixel which is required to display black, according to an image to be displayed; and inputting, by the controller, a second driving signal to a pixel electrode of a pixel driving circuit corresponding to a pixel which is required display white, according to the image to be displayed. A driving stage of the electronic paper display apparatus comprises a first homogenization stage which comprises a plurality of homogenization sub-stages. At a last homogenization sub-stage, the first and second driving signals comprise first and second driving sub-signals, respectively. Voltages of the first driving sub-signal and the second driving sub-signal have polarities opposite to polarities of the black particles and the white particles, respectively.

Abstract: A liquid cooling apparatus and a liquid cooling device. The liquid cooling apparatus includes a rigid tube and a flexible tube, where the rigid tube is securely disposed in a cabinet and communicates with a liquid cooling source, and a through hole is opened in a side wall of the rigid tube and passes through the side wall, and one end of the flexible tube is in contact with the rigid tube and communicates with the rigid tube in a sealed manner by using the through hole, and the other end of the flexible tube communicates with a cooling tube in a blade server.

Abstract: A chassis includes a main body having a backplane, a top cover plate, a bottom cover plate and left and right side plates connected with each other. An upper slide rail and a lower slide rail for securing single boards are provided in the main body, a fan is arranged at the upper position of the main body and a power distribution unit is arranged at the lower position of the main body, and a coupling element for coupling the fan with the power distribution unit is provided in the chassis. The coupling element may be a groove extending from the upper position to the lower position for accommodating cables and formed in the inner side of the side plate of the chassis, or may be two openings for passage of cables respectively provided at an upper position and a lower position of the side plate of the chassis.

Abstract: A chassis includes a main box body. The said main box body includes a back panel, an upper cover panel, a lower cover panel, a left side panel and a right side panel connected with each other. An upper single panel slideway and a lower single panel slideway are provided in the main box body for fixing single panels. A fan is provided on the top of the main box body. A power distribution unit is provided on the bottom of the main box body. A connection portion is provided in the chassis for connecting the fan and the power distribution unit. The connection portion is a groove provided from the top to the bottom of the side panel for holding acable or two holes provided on the upper and the lower locations of the side panel for guiding the cable.
