Abstract: An antenna device includes an insulating carrier and a first primary antenna having a first feeding-in section, a first auxiliary antenna having a second feeding-in section and a second grounding section, a second primary antenna having a third feeding-in section, a second auxiliary antenna having a fourth feeding-in section and a grounding face which are provided on a face of the carrier. The first primary and auxiliary antennas and the second primary and auxiliary antennas are positioned at two side edges of the carrier which are away from each other. The grounding face is positioned between both the first primary and auxiliary antennas and the second primary and auxiliary antennas. The grounding face is provided with a first grounding section adjacent to the first feeding-in section, a third grounding section adjacent to third feeding-in section and a fourth grounding section adjacent to the fourth feeding-in section.

Abstract: The present application discloses a device and a method for generating a look up table, and relates to the technical field of look up tables.

Abstract: The present disclosure describes methods of contrast enhancement and dual-cell display apparatus. The method includes receiving an RGB value of each second pixel of a displayed image, and determining a brightness value of each first pixel according to the RGB value of each second pixel. The method also includes determining a local brightness adjustment factor and a global brightness adjustment factor by performing statistics processing for local region brightness values and global image brightness values according to the brightness value of each first pixel; and calculating a brightness drive signal corresponding to the first pixel, according to the brightness value of each first pixel, the local brightness adjustment factor and the global brightness adjustment factor. The brightness drive signal adjusts a transmittance of a corresponding pixel of the first panel. The global brightness adjustment factor adjusts an output brightness value of a corresponding pixel of the first panel.

Abstract: Systems and methods are provided for managing navigation among applications installed on an electronic device. According to certain aspects, an electronic device receives (1502) a selection of a graphical item displayed by a source application and an instruction to copy the graphical item. The electronic device stores (1514) an identification of the source application in a data record and navigates (1522) to a destination application. Further, the electronic device receives (1538) a command to paste the graphical item within the destination application and return to the source application, examines (1560) the data record to identify the source application, and automatically navigates (1570) to the source application.

Abstract: An electronic device includes a main body, an installing assembly, a support, and a connecting assembly. The main body includes a shell and a display screen installed in the shell. The installing assembly is connected to a side of the shell opposite to the display screen. The connecting assembly is rotatably connected between the installing assembly and the support. The support includes a connecting pole and two opposite extending poles perpendicularly extending out from two opposite ends of the connecting pole. The connecting pole and the extending poles cooperatively bound a receiving space. The connecting assembly can be rotated to be received in the receiving space.
