Abstract

An embodiment of the present invention provides a mobile terminal. The mobile terminal includes a display screen, a main board, and a photoelectric fingerprint identification module; , an upper substrate and a polarizer; the main board is provided with at least two groups of power interfaces; the driving circuit board includes at least two driving circuit sub-boards, and each driving circuit sub-board is connected to a different power interface group on the main board ; The photoelectric fingerprint recognition module is arranged below the lower substrate, in the area facing a single drive circuit sub-board, and the power supply voltage of the drive circuit sub-board of the photoelectric fingerprint recognition module is arranged below, which is higher than that of other drivers Power supply voltage for the daughter board. Through the mobile terminal provided by the embodiment of the present invention, it is possible to control the highlighted display of a local area of ​​the display screen.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a mobile terminal. Background technique [0002] The display screen of a mobile terminal is a window for consumers to sense the mobile terminal, so the design of the display window is particularly important for the mobile terminal. At present, 2D displays, 2.5D curved glass displays, and 3D curved screens can no longer meet the individual needs of users. Therefore, in order to bring consumers a better consumption experience, OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) full-screen Came into being. Full screen refers to a screen design with a screen-to-body ratio close to 100%. The upper, left, and right borders of the display module itself are less than 0.5mm, and the lower border is smaller than 3mm. The AA (Active Area, effective display) area far exceeds the current 80% screen-to-body ratio. design. In the full-screen design, since the fr...
