Mainboard device of three-rear-camera mobile phone

Abstract

The invention discloses a mainboard device of a three-rear-camera mobile phone. The mainboard device comprises a PCB (Printed Circuit Board); a through hole area arranged at the right end of the PCB,and a color lens and a telephoto lens arranged on the through hole area; a black-and-white area arranged above the through hole area, and a black-and-white lens arranged in the black-and-white area; an antenna area arranged above the black and white area; and an antenna control chip arranged on the back surface of the PCB and matched with the black and white area, wherein the color lens, the telephoto lens, the black and white lens and the antenna control chip are electrically connected with the PCB respectively, and the antenna area is electrically connected with the antenna control chip. Byadopting the design, the distance from the antenna to the control chip is greatly reduced through the adjustment of the camera, the path loss of the antenna is effectively reduced, the component areaof the PCB is increased, and the antenna can be effectively applied to the design of mobile phones with more functions and higher integration at present.

Description

technical field [0001] The invention relates to a mobile phone, in particular to a mainboard device of a three-rear-camera mobile phone. Background technique [0002] Most of the LCD screens of mobile phones now use the beautiful water drop screen design, and most camera models have also been changed to three rear cameras with higher pixels, larger angles, and better imaging (color lens + a black and white lens + A telephoto lens) design. On the left and right sides of the phone, one side is the card holder for the TFLASH / SIM card, and the three rear cameras are placed on the other side. Due to the height of the three rear cameras, in order not to protrude too much from the back shell of the mobile phone, a piece of the motherboard PCB will be hollowed out, and the cameras will be sunk into the PCB motherboard. Above the three cameras and on the corners of the mobile phone, this area is the antenna area of ​​the mobile phone. The WIFI / GPS control chip can only be set on on...

Problems solved by technology

Above the three cameras and on the corners of the mobile phone, this area is the antenna area of ​​the mobile phone. The WIFI / GPS control chip can only be set on one side of the three rear cameras, so that the WIFI / GPS control chip and the antenna area The distance between them is long, there will be a length of 10-20mm, which will cause the antenna gain to lose 1-2dB on this path
