Abstract

The invention discloses a mobile terminal and a method for controlling positive and negative voltage output of a display screen based on the mobile terminal. In the method, the negative voltage power supply terminal and the positive voltage power supply terminal of the mobile terminal display screen are connected to the battery through the intermediate circuit in advance; When the user's instruction to turn on the screen is detected, the intermediate circuit is controlled to output positive and negative voltages at the same time; and then the display-related initialization program is executed. The positive voltage and negative voltage of the display screen are output at the same time to speed up the initialization of the display screen and avoid unnecessary delay waiting time, so as to speed up the display performance of the display screen and provide convenience for users.

Description

technical field [0001] The present invention relates to the field of mobile terminals, in particular to a mobile terminal and a method for controlling positive and negative pressure output of a display screen based on the mobile terminal. Background technique [0002] Mobile terminal display has always been a battleground among mobile terminal manufacturers; at present, mobile terminals all use large-screen, high-definition, high-resolution display screens, so as to achieve the best display effect and meet users' increasing demand for display screens. Increased requirements. For the display screen, its display often requires a positive voltage and a negative voltage. In the prior art, the power management chip of the mobile terminal outputs two voltages (one positive voltage and one negative voltage respectively) by setting the positive voltage and the negative voltage respectively. voltage, a negative voltage) to supply power to the display. [0003] In the existing techn...
