Embodiment Construction

[0024] The main technical idea of ​​the present invention is that by adding a control module to the organic light-emitting display unit for mobile phones, when the OLED display screen does not need to display, the control module can cut off the battery voltage input to the booster module, thereby solving the problem that the mobile phone is in standby mode. Or in the shutdown state, the OLED driver module still has the problem of partial current consumption, which reduces the standby current of the mobile phone and improves the standby time of the mobile phone.

[0025] The specific implementation process of the present invention will be further described in detail below in conjunction with each accompanying drawing.

[0026] Please refer to Figure 3, which is a structural block diagram of the organic light-emitting display unit in the mobile phone of the present invention, which mainly includes an interface module, a control module, a boost module, an OLED drive module and an ...

Abstract

The present invention discloses an organic light-emitting display unit used in a mobile telephone, which comprises a boost module, an OLED driving module, an OLED display screen and a control module, wherein said control module is used for receiving battery voltage, inputting battery voltage to the boost module when OLED enable signal is put high and shutting off battery voltage input to the boost module when OLED enable signal is put low. The present invention further discloses a method used for lowering power consumption of a mobile telephone and comprising the follwong steps: judging states of the OLED enable singal, inputting battery voltage to the boost module when the OLED enable signal is put high and shutting off battery voltage input to the boost module when the OLED enable signal is put low. The present invention resolves the problem that part current consumption still exists in the OLED driving module when a mobile telephone is kept in standby or shutdown condition, reduces current in a mobile telephone in standby condition, and improves work time of a mobile telephone.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to an organic light-emitting display unit in a mobile phone and a method for reducing power consumption of the mobile phone. Background technique [0002] As a communication tool frequently used by modern people, mobile phones have become an indispensable necessity in daily life. As consumers gradually increase their demand for mobile phones as fashionable consumer goods, at the same time, in order to be able to meet the increasingly fierce demand for mobile phone products To establish an advantage in the competition, all mobile phone manufacturers are now actively adopting display screens with better display effects. [0003] OLED (Organic Light Emitting Display, Organic Light Emitting Display) unit does not need a backlight, and the overall structure thickness is relatively thin, so it has a good application prospect in ultra-thin mobile phones. Wider and more responsive...
