The video processor includes: a receiving module, configured to receive source video display data and parse the source video display data as valid video display data; a pre-processing module, configured to generate valid video display data in a predetermined video format; an image quality processing module, configured to adjust image quality parameters to output a first video screen; a post-processing module, configured to extract video parameters, generate a blended screen, and blend the blended screen on the first video screen; and a video output module, configured to perform data format conversion on valid video display data of the first video screen and valid video display data of the blended screen to encapsulate as output video display data, and output the output video display data to an external display to blend the blended screen on the first video screen.

Abstract: A new antenna array of the invention which has simple structure, small volume and can adopt a variety of realization forms, it can be easily integrated in the PCB of the mobile terminal using surface mount technology (SMT) or multi-layer PCB integration and other forms of technology. The antenna array is compact and can be configured with different number of antenna elements to meet the gain requirements. The antenna array is small in size and has a wide antenna bandwidth that can cover multiple 5G millimeter-wave bands while maintaining a directional high antenna gain and a stable radiation pattern. The antenna array can satisfy the millimeter-wave 5G communication requirements such as high gain, beam forming characteristics, beam scanning characteristics, and can be easily integrated into a portable mobile terminal.

Abstract: A novel antenna element includes a PCB, a radiating element disposed on the surface of the PCB, and a feed structure. The radiating element is constituted by a magnetic dipole and an electric dipole. The magnetic dipole comprises a first magnetic dipole conductive part disposed on the first surface, a second magnetic dipole conductive part disposed on the second surface, and a first metal via array which penetrates the PCB and is connected with edges of the first and second magnetic dipole conductive parts. The electric dipole is constituted by a first electric dipole conductive part which is connected with the first magnetic dipole conductive part and a second electric dipole conductive part which is connected with the second magnetic dipole conductive part. The feed structure is connected with the first magnetic dipole conductive part and the magnetic dipole extends to the ground.

Abstract: An antenna system applied in the metal back cover of a 5G mobile terminal contains a metal back cover, a feeder line and at least one antenna element. The metal back cover is composed of a bottom case & a frame. The antenna element is composed of a feed screw, a pillar, a insulating sleeve and a reflecting cavity.
