[0002] Flexible screens expand the screen area of ​​mobile phone terminals, allowing the screen to expand and display content in a larger space. Currently, flexible screens on the market include scroll screens and folding screens. For scroll screen mobile phone terminals, there are two forms: retracted state and extended state. In the retracted state, the expanded screen is hidden inside the terminal by the scroll. In the extended state, the extended screen is unfolded and presented to the user by rotating the scroll, thereby achieving the expansion of the display screen.

[0047] Regarding the problem that the unfolded state of the existing scroll screen involved in the background technology will lead to an increase in screen energy consumption, resulting in a low terminal battery life and reduced terminal usage life.

[0048] The present application provides a solar-powered flexible screen terminal 1, which includes a main screen 11, a flexible screen, a connecting mechanism, a supporting mechanism, a solar cell panel 19, an ambient light sensor and a central processing unit.

[0049] The main screen 11 and the flexible screen are connected by a connecting mechanism, which includes a scroll mechanism or a hinge mechanism 15. Depending on the connection mechanism, the connection method between the main screen 11 and the flexible screen also varies. Specifically, when the connection mechanism is a scroll mechanism, the support mechanism is arranged on the back of the main screen 11 and is connected to the scroll mechanism and the flexible screen respectively.

[0050] When the connecting mechanism is a hinge mechanism 15, the supporting mechanism is arranged on the back of the flexible screen and is connected to the hinge mechanism 15. When the hinge mechanism 15 drives the supporting mechanism to rotate, the flexible screen rotates and moves around the length direction of the main screen 11, and the flexible screen is unfolded on one side of the main screen 11. The solar cell panel 19 is arranged on the back of the supporting mechanism and the main screen 11, so that photoelectric energy conversion can be performed when the flexible screen is unfolded.

[0051] The central processing unit is connected to the solar panel 19 and the ambient light sensor respectively, and is used to obtain the output voltage of the solar panel 19 and the light intensity detected by the ambient light sensor, and to determine whether to charge the flexible screen terminal 1 based on the obtained data.

[0052] The flexible screen terminal 1 can be a mobile phone with a foldable screen, a tablet computer, a laptop computer with a touch-sensitive surface (such as a touch panel), or other portable electronic devices. The solar cell panel 19 can be a crystalline silicon cell panel, an amorphous silicon cell panel, a chemical dye cell panel, or a flexible solar cell.

[0053] In a specific application scenario, see Figure 1-2 The connecting mechanism includes a scroll mechanism, and the scroll mechanism includes a scroll body provided on one side or both sides of the length direction of the main screen 11, and the flexible screen is wound around the scroll body. The supporting mechanism is provided on the back of the main screen 11, and the supporting mechanism includes a supporting column parallel to the scroll body and a plurality of mutually interlocking parallel supporting bars provided perpendicular to the supporting column. The scroll mechanism includes a scroll drive provided at both ends of the scroll body, and the scroll drive is movably connected to the supporting column. The scroll drive is used to drive the supporting column to make the support bar move translationally relative to the main screen 11, so that the flexible screen is unfolded along the support bar on one side or both sides of the main screen 11. The solar cell panel 19 is provided on the surface of the support bar so that it performs photoelectric energy conversion when the flexible screen is unfolded. Specifically, the scroll drive can be a gear drive or a belt drive.

[0054] In a preferred embodiment, Figure 1 It is a schematic diagram of the back structure of the flexible screen terminal 1 of the present application, in which the flexible screen is unfolded on both sides of the main screen 11. The scroll body includes a first scroll body 12 and a second scroll body 13 arranged on both sides of the length direction of the main screen 11, and the flexible screen is wound on the first scroll body 12 and the second scroll body 13 respectively. The support column includes a first support column 16 and a second support column 17 respectively arranged on the outside of the first scroll body 12 and the second scroll body 13, and the support bar includes a first support bar 161 and a second support bar 171 respectively connected to the first support column 16 and the second support column 17, and the scroll drive is connected to the first support column 16 and the second support column 17 respectively, and drives the first support column 16 and the second support column 17 to move in a translational motion away from the main screen 11 in opposite directions, so that the flexible screen is unfolded on both sides of the main screen 11 along the first support bar 161 and the second support bar 171 respectively.

[0055] In a preferred embodiment, in order to reduce the power loss and complex design caused by the reel mechanism.

[0056] The support column includes a third support column 18 arranged on the outside of the third scroll body 14, and the support bar includes a third support bar 181 connected to the third support column 18. The scroll drive is connected to the third support column 18 and drives the third support column 18 to move translationally away from the main screen 11, so that the flexible screen can be unfolded along the third support bar 181 on one side of the main screen 11.

[0057] like Figure 3 As shown, it is a schematic diagram of the back structure of the flexible screen of the flexible screen terminal 1 in this application when the main screen 11 is unfolded. When the connecting mechanism includes a hinge mechanism 15, the flexible screen is arranged on the supporting mechanism, and the supporting mechanism is connected to the main screen 11 through the hinge so that the flexible screen can be unfolded relative to the main screen 11 or folded back.

[0058] The solar cell panel 19 is arranged on the back of the supporting mechanism and the main screen 11 and performs photoelectric energy conversion when the flexible screen is unfolded. The hinge mechanism 15 can be a damping hinge.

[0059] Corresponding to the above-mentioned solar-powered flexible screen terminal, please refer to Figure 4 The present application also provides a solar power supply method, which is applied to the flexible screen terminal. The method comprises a central processor performing the following steps:

[0060] Step S41: determining the expanded or contracted state of the flexible screen, and obtaining the first ambient light detected by the ambient light sensor when the flexible screen is in the expanded state.

[0061] The expanded or contracted state of the flexible screen indicates its position relative to the main screen. When the flexible screen overlaps the main screen or is rolled up, it is determined to be in the contracted state; when the flexible screen and the main screen are in the same plane, it is determined to be in the expanded state.

[0062] Step S42: when the first ambient light exceeds a first light threshold and lasts for a specific time, obtaining a first output voltage of the solar panel.

[0063] Step S43: When the first output voltage exceeds a power supply voltage threshold, controlling the solar panel to supply power to the battery of the terminal.

[0064] The ambient light sensor is used to detect ambient light intensity. The greater the light intensity, the more photoelectric energy the solar panel converts, and the greater the output voltage provided. The first ambient light and the first output voltage are positively correlated. The supply voltage is the minimum voltage value required to stably power the flexible screen terminal, and the first light threshold is the minimum light intensity value required for the solar panel to stably convert the output supply voltage. This specific time ensures the stability of the light intensity, and thus the stability of the output voltage.

[0065] Therefore, when the flexible screen is unfolded, the solar panel is exposed to the external environment. The ambient light enables the solar panel to convert photoelectric energy and charge the flexible screen terminal when the above conditions are met, thereby reducing the power loss of the flexible screen terminal and improving the stability of solar charging.

[0066] Typically, the expanded or contracted state of the flexible screen is determined by angle sensors provided on the flexible screen and the main screen. When the angle obtained by the angle sensor is zero or 180 degrees, it is determined that the flexible screen is expanded relative to the main screen. However, the present application can determine that the flexible screen is in the contracted state when the solar panel is hidden inside the terminal. In a preferred embodiment, determining the expanded or contracted state of the flexible screen includes:

[0067] Acquire second ambient light detected by the ambient light sensor.

[0068] When the second ambient light exceeds a second light threshold and lasts for a specific time, a second output voltage of the solar panel is obtained, wherein the second light threshold is less than the first light threshold.

[0069] When the second output voltage exceeds the display voltage threshold, it is determined that the flexible screen is in the unfolded state, wherein the display voltage threshold is less than the power supply voltage threshold.

[0070] The second light threshold is used to indicate the light intensity of the flexible screen terminal in dark or low-light conditions. The flexible screen terminal can distinguish whether it is currently in dark or low-light conditions. This avoids the situation where the solar panel outputs a weak voltage when the flexible screen is in the unfolded state in dark or low-light conditions, and the flexible screen is mistakenly judged to be in the folded or retracted state. The display voltage threshold is used to indicate the minimum voltage value of the solar cell when it is exposed to the external environment.

[0071] As the flexible screen moves with the support bars, the solar panel is exposed to the outside world. At this point, the solar panel's output voltage is greater than the display voltage threshold. Conversely, if the solar panel's output voltage is less than the display voltage threshold, it indicates that the solar panel is hidden within the flexible screen terminal and the flexible screen is in a retracted state.

[0072] In a preferred embodiment, the method further comprises:

[0073] The working state of the connecting mechanism is determined according to the expanded or contracted state of the flexible screen.

[0074] The operating status of the connection mechanism indicates whether the scroll mechanism and hinge mechanism are operating abnormally. For example, it can indicate whether the scroll mechanism has reached its upper limit for scrolling, or whether the hinge mechanism has reached its upper limit for rotation. Wear and tear of the connection mechanism in flexible screen terminals also affects the user experience. Therefore, the above method can provide timely information on the operating status of the connection mechanism, allowing users to provide feedback and make adjustments.

[0075] Corresponding to the above-mentioned solar power supply method for a flexible screen terminal, as Figure 5 As shown, the present application also provides a solar power supply device 500 for a flexible screen terminal, comprising:

[0076] A first ambient light acquisition module 510 is configured to acquire first ambient light detected by the ambient light sensor when the flexible screen is in the unfolded state;

[0077] A first output voltage acquisition module 520 is configured to acquire a first output voltage of the solar panel when the first ambient light exceeds a first light threshold and lasts for a specific time;

[0078] The power supply module 530 is configured to control the solar panel to supply power to the battery of the terminal when the first output voltage exceeds a power supply voltage threshold.

[0079] In an optional embodiment, the apparatus 500 further includes:

[0080] The second ambient light acquisition module is configured to acquire the second ambient light detected by the ambient light sensor.

[0081] The second output voltage acquisition module is configured to acquire a second output voltage of the solar panel when the second ambient light exceeds a second light threshold and lasts for a specific time, wherein the second light threshold is less than the first light threshold.

[0082] The unfolding state acquisition module is used to determine that the flexible screen is in the unfolded state when the second output voltage exceeds the display voltage threshold, wherein the display voltage threshold is less than the power supply voltage threshold.

[0083] In an optional example, the apparatus 500 further includes:

[0084] The working state determination module is used to determine the working state of the connecting mechanism according to the expanded or contracted state of the flexible screen.

[0085] This application sets a solar panel on a flexible screen terminal so that when the flexible screen terminal is in the unfolded state, the solar panel can perform photoelectric conversion and supply power to the terminal. At the same time, the power supply method provided by this application monitors the ambient light and the output voltage of the solar panel in real time, and judges whether the terminal is in the unfolded state and whether it can continue to meet the stable charging requirements of the terminal battery based on the current light intensity and the output voltage of the solar panel. The solution of the present invention can realize the replenishment of terminal power when the screen is in the expanded state, and at the same time, the screen expansion state can be fed back and detected by the voltage output of the solar panel, thereby improving the user experience.
