Display with solar module and power supply method thereof

Abstract

The invention relates to a display with solar module and a power supply method thereof. The display comprises a battery, a main circuit, a maintaining circuit, a panel, a backlight module and a solar module, wherein the battery supplies power to the main circuit in order to lighten the backlight module and display images on the panel, the backlight module is arranged between the panel and the solar module, external lights outside of the display body can be received by the solar module through the panel or internal lights generated by the backlight module are received by the solar module when the display opens the panel and the backlight module, and when the external lights or the internal lights are received by the solar module, the solar module generates solar voltage to supply power to the maintaining circuit to maintain standby function. With the help of the display with the solar module, both the time of maintaining standby function and the working time of the battery can be prolonged.

Description

technical field The present invention relates to a display with a solar module and a power supply method thereof, in particular to a display in which a solar module circuit that can receive external light or internal light of the display supplies power to some circuits inside the display, and the application of the solar module method. Background technique With the advancement of technology, the use of various personal devices has become more and more common. Various small and battery-powered displays: for example, digital photo frame (DPF), mobile phone, handheld computer (PDA), mobile Internet device (MID), etc. It will be limited by battery capacity, and its display time or talk time will be more and more tested. Especially in outdoor places, it is difficult to find a socket for charging and maintain the normal power supply of the battery. For this reason, people try to utilize solar module to charge battery. The solar module can receive sunlight or artificial light, ...

AI Technical Summary

Problems solved by technology

For example: maintaining the real time (Real Time Clock), time display and maintaining the remote control line standby; when the battery 14 is removed for power supply, the panel 11 and the backlight module 12 stop operating at the same time, and the maintenance circuit 16 is still powered by the energy storage component. Supplying electric energy to maintain the operation of specific functional circuits; when the battery 14 is installed in the display 10, the battery 14 will charge the energy storage component and consume the electric energy in the battery,

In addition, the solar module 13 and the mains can be coupled to the charging unit 17. For detailed operation content, please refer to the content of US Pat. But if the battery is not installed in the state of the display or the switch completely cuts off the power supply of the battery, the maintenance circuit 16 can only be supplied with electric energy by the energy storage component to maintain the operation of the specific function circuit. The energy storage component is usually a gold capacitor (button type) or wound capacitors) have a limited storage capacity, and when the power is exhausted, the function to be maintained will be interrupted, causing inconvenience to the user

In addition, the solar modules in the prior art are usually installed on the outside of the electronic device, and the charging unit is connected to the terminal. It is inconvenient to carry the solar module in addition, or it can be installed on the outer surface of the electronic device, but it is not convenient for the electronic device. the appearance of the installation can cause visual disturbance
