Abstract: A display apparatus includes a display module and a camera module. The camera module is within a display area of the display module, and the camera module is over a side of the display module distal to a light-emitting surface of the display module. The display area of the display module includes a light-incident region positionally corresponding to a lens of the camera module, wherein the light-incident region is configured to allow lights from a side of the display apparatus proximal to the light-emitting surface of the display module to pass therethrough to thereby enter the lens of the camera module. The display apparatus further includes a backlight portion over a side of the display module distal to the light-emitting surface of the display module, and the camera module is arranged inside a mounting hole in the backlight portion.

Abstract: Disclosed are a lead-free, high-sulphur and easy-cutting copper-manganese alloy and preparation method thereof. The alloy comprises the following components in percentage by weight: 52.0-95.0 wt. % of copper, 0.01-0.20 wt. % of phosphorus, 0.01-20 wt. % of tin, 0.55-7.0 wt. % of manganese, 0.191-1.0 wt. % of sulphur, one or more metals other than zinc that have an affinity to sulphur less than the affinity of manganese to sulphur, with the sum of the contents thereof no more than 2.0 wt. %, and the balance being zinc and inevitable impurities, wherein the metals other than zinc that have an affinity to sulphur less than the affinity of manganese to sulphur are nickel, iron, tungsten, cobalt, molybdenum, antimony, bismuth and niobium.

Abstract: A mobile terminal touch control display structure and a manufacturing method thereof, and a mobile terminal are disclosed.

Abstract: An outer ring of an inner joint of the constant speed transmission shaft is provided with a vehicle speed sensor rotating synchronously with the inner joint, and the drive axle is fixedly equipped with a signal collecting device opposite to the vehicle speed sensor and configured to monitor a rotation speed signal of the vehicle speed sensor. The inner joint of the constant speed transmission shaft transmits torque during the running of a vehicle, and through monitoring a rotation speed of the inner joint, the rotation data of rear wheels can be obtained. By mounting the vehicle speed sensor on the inner joint and fixing the signal collecting device on the drive axle for monitoring the rotation speed signal of the vehicle speed sensor, the signal reading is stable, which facilitates the maintenance, reduces the cost, and can satisfy the environmental requirements.

Abstract: Disclosed herein are compounds having the structure of Formula I and pharmaceutically suitable salts, esters, and prodrugs thereof that are useful as antibacterially effective tricyclic gyrase inhibitors. Related pharmaceutical compositions, uses and methods of making the compounds are also contemplated.

Abstract: A display device and a method for manufacturing the display device are provided.

Abstract: A quick disassembly tool for fixedly mounting a connection module is provided according to the present application, including a pressing block and a fixing block for press-fitting the connection module. A press-fitting end face of the fixing block is provided with a press-fitting hole, and a press-fitting post inserted into the press-fitting hole protrudes from the pressing block; the quick disassembly tool further includes a locking device respectively pressing on an end of the pressing block and an end of the fixing block, and the locking device includes an elastic pressing device configured to adjust a press-fitting space between the pressing block and the fixing block. The pressing block and the fixing block are connected and transversely position-limited through the press-fitting hole and the press-fitting post, the locking of the pressing block and the fixing block in a pressing direction is achieved by a locking device.
