Problems solved by technology

However, this solution has the following defects: First, additional hardware support is required, which not only increases the manufacturing cost, but also makes the hardware circuit more complicated; secondly, when the time of the mobile phone is reset during use, it is necessary to update the time of the additional electronic watch synchronously, which is more troublesome ; Again, when the mobile phone is turned off for a long time, since it cannot be corrected according to the time of the mobile phone, the error between the electronic watch circuit and the mobile phone clock circuit will make the time displayed by the electronic watch inconsistent with the mobile phone time

Embodiment Construction

[0017] see figure 1 , figure 1 It is a flow chart of knowing the time after shutdown according to the present invention. First, when the power-off button of the mobile phone is pressed, the system judges whether the function of displaying the time in the power-saving mode is activated. If not activated, the mobile phone is normally shut down; if the function is activated, Then the system reserves the power supply of the processor and the basic circuit, where the basic circuit includes the clock circuit and the screen display control circuit; then the clock circuit sends time data signals to the processor at regular intervals, because the time displayed on the screen of the mobile phone is usually accurate to the minute , so this time interval can be set to one minute; after the processor receives the time data signal, it transmits the time data signal to the screen display control circuit; then the screen display control circuit displays the time on the screen; at the same tim...

Abstract

The method to display time on mobile phone comprises: (1) once pressing the shut-down button, the system decides whether it is success to show time on power-saving mode; (2) if yes, system turns to power-saving mode, and keeps power supply as well as control circuit for processor and screen; (3) the clock circuit sends time data signal to the processor periodically; (4) the processor sends said signal to the control circuit; (5) it shows time on screen. Compared with normal state, this invention reduces power consumption effectively.

Description

【Technical field】 [0001] The invention relates to the field of mobile phone applications, more specifically, to a method for displaying time when the mobile phone is in a power-saving state. 【Background technique】 [0002] For the prior art related to the present invention, please refer to the Chinese Patent No. 200420042983.7 issued on February 16, 2005. This utility model is provided with an additional electronic watch circuit and a switch electronic circuit in the mobile phone display circuit, so that after the mobile phone is turned off, The time can also be displayed on the low-power screen of the attached electronic watch, which saves the power of the mobile phone on the one hand and brings convenience to the user on the other hand. However, this solution has the following defects: First, additional hardware support is required, which not only increases the manufacturing cost, but also makes the hardware circuit more complicated; secondly, when the time of the mobile p...
