A display device control circuit

Abstract

The invention belongs to the technical field of mobile terminal display equipment, and in particular relates to a display device control circuit, which controls the system by setting a second control switch composed of a PMOS transistor and an NPN transistor between the system power supply and the OLED display module driving circuit When the power supply is in the on or off state of the OLED display module, the purpose of power saving is effectively achieved, the power consumption is reduced, and the use time of the mobile device is greatly extended.

Description

technical field [0001] The invention belongs to the technical field of mobile terminal display equipment, and in particular relates to a display device control circuit. Background technique [0002] With the development of electronic equipment, mobile terminals have been seen everywhere in people's lives. The biggest feature of mobile terminals is that they have extremely high requirements for power consumption, because it is difficult for users to get charged all the time. Therefore, it is necessary to extend the use time of the equipment. , can only reduce the power consumption of the mobile terminal as much as possible, which is also the pursuit of various mobile device companies at present. [0003] There are many ways to reduce mobile power consumption, but they are nothing more than software and hardware. At present, most of them are realized by software, or by combining software with hardware, or by using hardware. It is easier to reduce high power consumption, and th...

Problems solved by technology

[0003] There are many ways to reduce mobile power consumption, but they are nothing more than software and hardware. At present, most of them are realized by software, or by combining software with hardware, or by using hardware. It is easier to reduce high power consumption, and the effect is immediate. , but the management of weak leakage current is basically realized by software. For the mobile terminal display module, the existing technology is to turn off various unused circuits and modules, that is, to let some functional modules enter the dormant state. Power saving, but even so, these circuits are still in the energized state. Although the weak voltage is not enough to turn on the working mode, the electronic devices are in a weak leakage state, and software cannot fundamentally solve the problem of weak leakage from hardware
