Fig. 1 illustrates a schematic structural diagram of an electronic device according to an embodiment of the present application, where the electronic device is a mobile phone, a tablet computer, a smart watch, or the like. As shown in fig. 1, the electronic apparatus includes: casing 1, display module 2, control circuit 3 and battery module 4.

The housing 1 includes a back cover and a bezel, and the back cover is hermetically connected to one side of the bezel to form the housing 1 having one side opened.

In addition, under the condition that the solar power generation layer charges the battery module, the electronic equipment charged by the power adapter and the charging seat is prevented from being used, so that potential safety hazards are reduced, and meanwhile, the design of a charging interface on the electronic equipment is avoided for the electronic equipment charged by the power adapter, so that the attractiveness of the electronic equipment is improved; for the electronic equipment charged by the solar cell arranged on the back cover, the solar cell arranged on the back cover is avoided, and the attractiveness of the electronic equipment is improved.

The transparent cover 211, the display body layer 212 and the transparent substrate 213 are adhered by an insulating transparent adhesive, and may be fixedly connected in other ways as long as light transmission can be ensured. When the transparent display layer 21 and the solar power generation layer 22 are fixedly connected, the transparent base 213 included in the transparent display layer 21 is bonded to the solar power generation layer 22.

In the embodiment of the present application, as shown in fig. 3 or fig. 4, the display body layer 212 includes at least one pixel region 2121 and at least one hollow region 2122, and the at least one pixel region 2121 is fully covered on the entire display body layer 212 to ensure that the displayed image is fully covered on the display module 2. The at least one hollowed-out area 2122 is configured to allow transmission of external ambient light, thereby ensuring that the external ambient light can sequentially pass through the transparent cover 211, the display body layer 212, and the transparent subbase 213 to irradiate onto the solar power generation layer 22.

Each pixel region 2121 includes a display region corresponding to at least one pixel unit, and each pixel unit includes three sub-pixels R, G, and B, or includes four sub-pixels R, G, B, and W. The arrangement of the plurality of sub-pixels included in the pixel unit may refer to the related art.

In the embodiment of the present application, the specific structure of the display body layer 212 may refer to the specific structure of the transparent display screen in the related art, for example, refer to the structure of the transparent LED display screen in the related art or refer to the structure of the transparent OLED display screen in the related art. Next, an explanation will be given of a display body layer 212, taking the structure of the transparent OLED display panel as an example.

As shown in fig. 5, the display body layer 212 includes an anode layer 2123, a hole transport layer 2124, a light emitting layer 2125, an electron transport layer 2126 and a cathode layer 2127, and the anode layer 2123, the hole transport layer 2124, the light emitting layer 2125, the electron transport layer 2126 and the cathode layer 2127 are sequentially stacked and fixed in a direction from the transparent cover 211 to the transparent base 213.

The positive output electrode of the battery module 4 is electrically connected to the positive electrode layer 2123 through the control circuit 3, and the negative output electrode of the battery module 4 and the cathode layer 2127 are both grounded, so that under the stimulation of the current provided by the battery module 4, the positive electrode layer 2123 releases holes and transmits the holes to the light-emitting layer 2125 along the hole transport layer 2124, the cathode layer 2127 releases electrons and transmits the electrons to the light-emitting layer 2125 along the electron transport layer 2126, the holes and the electrons are combined in the light-emitting layer 2125 to generate excitons, and the excitons are radiated and jump to emit photons to realize light emission.

The anode layer 2123, the hole transport layer 2124, the light emitting layer 2125, the electron transport layer 2126 and the cathode layer 2127 each have a hollow area 2122, and the hollow areas 2122 of the layers overlap in the thickness direction of the display body layer 212, so that external ambient light can sequentially pass through the anode layer 2123, the hole transport layer 2124, the light emitting layer 2125, the electron transport layer 2126 and the cathode layer 2127.

In some embodiments, as shown in fig. 6, the solar power generation layer 22 includes a transparent insulating layer 221, a solar cell sheet 222, and a back sheet 223, the solar cell sheet 222 is located between the transparent insulating layer 221 and the back sheet 223, and a lighting surface of the solar cell sheet 222 faces the transparent insulating layer 221.

The transparent insulating layer 221, the solar cell sheet 222, and the back sheet 223 are laminated and fixed, and when the solar power generation layer 22 and the light-transmitting display layer 21 are fixed, the transparent insulating layer 221 is bonded to the light-transmitting display layer 21. The transparent insulating layer 221 is used for realizing insulation between the solar cell and the light-transmitting display layer 21, and the back plate 223 is used for realizing support of the solar cell 222.

The transparent insulating layer 221 is made of transparent insulating glue or transparent insulating glass, or may be made of transparent insulating plastic, as long as it can transmit external ambient light and realize insulation between the solar cell 222 and the light-transmitting display layer 21. The back plate 223 is a glass substrate or a plastic substrate.

As shown in fig. 7, the solar cell 222 includes at least one crystalline silicon solar cell 2221 and at least one thin film solar cell 2222. In this way, the solar cell 222 formed by the crystalline silicon solar cell 2221 and the thin-film solar cell 2222 can not only convert the light energy with high illumination intensity into electric energy, but also convert the light energy with low illumination intensity into electric energy, so that the charging of the battery module 4 by the solar power generation layer 22 can be conveniently ensured under different environments (outdoor and indoor).

Alternatively, the solar cell 222 includes a plurality of crystalline silicon solar cells 2221 and a plurality of thin film solar cells 2222. As shown in fig. 7, each of the crystalline silicon solar cells 2221 and the thin-film solar cells 2222 is in a strip structure, and the plurality of crystalline silicon solar cells 2221 and the plurality of thin-film solar cells 2222 are distributed in a staggered manner; or, the crystalline silicon solar cells 2221 and the thin-film solar cells 2222 are rectangular in structure, the plurality of crystalline silicon solar cells 2221 and the plurality of thin-film solar cells 2222 are arranged in a matrix, and the crystalline silicon solar cells 2221 and the thin-film solar cells 2222 are distributed in a staggered manner.

Optionally, the solar cell 222 includes a crystalline silicon solar cell 2221 and a plurality of thin film solar cells 2222, the plurality of thin film solar cells 2222 are arranged in a matrix, and the crystalline silicon solar cells 2221 are distributed among different thin film solar cells 2222 to form a crystalline silicon solar cell 2221 with a grid structure.

In combination with the structure of the light-transmitting display layer 21, if the transparent substrate 213 included in the light-transmitting display layer 21 is made of an insulating material, the transparent substrate 213 can insulate the solar cell 222 from the display main body layer 212, and thus the solar power generation layer 22 may not include the transparent insulating layer 221. If the material of the transparent insulating layer 221 is transparent insulating glass or transparent insulating plastic, the transparent insulating layer 221 can support the display body layer 212, and thus the transparent display layer 21 may not include the transparent base 213.

Next, the battery module 4 and the control circuit 3 in the embodiment of the present application will be explained in detail.

As shown in fig. 8, the battery module 4 includes a first battery 41 and a second battery 42, and the first battery 41 and the second battery 42 are electrically connected to the control circuit 3 respectively.

Since the control circuit 3 is electrically connected to the first battery 41 and the second battery 42, respectively, the state of the first battery 41 and the state of the second battery 42 can be controlled, respectively, so as to realize mutual backup of the first battery 41 and the second battery 42. For example, the control circuit 3 controls the solar power generation layer 22 to charge the first battery 41, and controls the second battery 42 to supply power to the light-transmitting display layer 21; or the control circuit 3 controls the solar power generation layer 22 to charge the second battery 42 and controls the first battery 41 to supply power to the light-transmitting display layer 21.

For the first battery 41, there are a case of charging to near full charge and a case of discharging to near empty charge. Therefore, the control circuit 3 detects the electric quantity of the first battery 41, then judges the electric quantity of the first battery 41, controls the solar power generation layer 22 to stop charging the first battery 41 when the first battery 41 is determined to be charged to be close to full electric quantity, and controls the second battery 42 to discharge when the first battery 41 is determined to be discharged to be close to empty electric quantity.

Optionally, the control circuit 3 is configured to, when the power of the first battery 41 gradually increases to be greater than or equal to the first power threshold, place the electrical connection between the first battery 41 and the solar power generation layer 22 in a disconnected state; when the electric quantity of the first battery 41 is gradually decreased to be less than or equal to the second electric quantity threshold value, the electrical connection between the first battery 41 and the light-transmitting display layer 21 is set to be in a disconnected state, the electrical connection between the first battery 41 and the solar power generation layer 22 is set to be in a connected state, the electrical connection between the second battery 42 and the solar power generation layer 22 is set to be in a disconnected state, and the electrical connection between the second battery 42 and the light-transmitting display layer 21 is set to be in a connected state.

The first electric quantity threshold is an electric quantity value when the first battery 41 is close to a full electric quantity, or an electric quantity value when the first battery 41 is close to an empty electric quantity, and the second electric quantity threshold is an electric quantity value when the first battery 41 is close to a full electric quantity. Illustratively, the first charge threshold is 95% or 100% of the rated charge of the first battery 41, and the second charge threshold is 3% or 5% of the rated charge of the first battery 41.

Wherein, the electric quantity of the first battery 41 gradually increases to be greater than or equal to the first electric quantity threshold value, which indicates that the first battery 41 is charged to be close to full charge, and no other operation is performed after the control circuit 3 disconnects the electrical connection between the first battery 41 and the solar power generation layer 22, that is, the second battery 42 continues to discharge to be close to empty electric quantity; alternatively, after the control circuit 3 sets the electrical connection between the first battery 41 and the solar power generation layer 22 to the disconnected state, the electrical connection between the first battery 41 and the transparent display layer 21 is set to the on state, the electrical connection between the second battery 42 and the transparent display layer 21 is set to the disconnected state, and the electrical connection between the second battery 42 and the solar power generation layer 22 is set to the on state, that is, the power supply from the first battery 41 is directly switched to the on state, and the second battery 42 is charged.

When the power of the first battery 41 is gradually decreased to be less than or equal to the second power threshold, the electrical connection between the second battery 42 and the solar power generation layer 22 is in a disconnected state, and the electrical connection between the second battery 42 and the solar power generation layer 22 does not operate; or the electrical connection between the second cell 42 and the solar power generation layer 22 is in a conducting state, and at this time, the controller switches the electrical connection between the second cell 42 and the solar power generation layer 22 to a disconnecting state.

The second battery 42 may be charged to a nearly full charge and then stopped, or may be discharged to a nearly empty charge. Therefore, the control circuit 3 detects the electric quantity of the second battery 42, then judges the electric quantity of the second battery 42, controls the solar power generation layer 22 to stop charging the second battery 42 when the second battery 42 is determined to be charged to be close to full electric quantity, and controls the first battery 41 to discharge when the second battery 42 is determined to be discharged to be close to empty electric quantity.

Optionally, the control circuit 3 is configured to place the electrical connection between the second battery 42 and the solar power generation layer 22 in a disconnected state when the power of the second battery 42 gradually increases to be greater than or equal to the first power threshold; when the electric quantity of the second battery 42 is gradually decreased to be less than or equal to the second electric quantity threshold value, the electrical connection between the second battery 42 and the light-transmitting display layer 21 is set to be in a disconnected state, the electrical connection between the second battery 42 and the solar power generation layer 22 is set to be in a connected state, the electrical connection between the first battery 41 and the solar power generation layer 22 is set to be in a disconnected state, and the electrical connection between the first battery 41 and the light-transmitting display layer 21 is set to be in a connected state.

When the electric quantity of the second battery 42 gradually increases to be greater than or equal to the first electric quantity threshold, it indicates that the second battery 42 is charged to be close to full charge, and no other operation is performed after the control circuit 3 disconnects the electrical connection between the second battery 42 and the solar power generation layer 22, that is, the first battery 41 continues to discharge to be close to empty; alternatively, after the control circuit 3 sets the electrical connection between the second battery 42 and the solar power generation layer 22 to the off state, the electrical connection between the second battery 42 and the light-transmitting display layer 21 is set to the on state, the electrical connection between the first battery 41 and the light-transmitting display layer 21 is set to the off state, and the electrical connection between the first battery 41 and the solar power generation layer 22 is set to the on state, that is, the power is directly switched to be supplied by the second battery 42, and the first battery 41 is charged.

When the electric quantity of the second battery 42 is gradually decreased to be less than or equal to the second electric quantity threshold, the electrical connection between the first battery 41 and the solar power generation layer 22 is in a disconnected state, and the electrical connection between the first battery 41 and the solar power generation layer 22 does not operate; or the electrical connection between the first cell 41 and the solar power generation layer 22 is in an on state, and at this time, the controller switches the electrical connection between the first cell 41 and the solar power generation layer 22 to an off state.

As shown in fig. 9, the control circuit 3 includes a voltage regulating circuit 31, a PMIC4 and a processor 33, the solar power generation layer 22 is electrically connected to the voltage regulating circuit 31, the voltage regulating circuit 31 is electrically connected to a power supply input terminal of the PMIC4, the first battery 41 is electrically connected to a connection terminal of the first battery 41 of the PMIC4, the second battery 42 is electrically connected to a connection terminal of the second battery 42 of the PMIC4, a signal terminal of the processor 33 is electrically connected to a signal terminal of the PMIC4, and the power supply input terminal of the processor 33 and the light-transmitting display layer 21 are both electrically connected to a power supply output terminal of the PMIC 4.

Thus, when the solar power generation layer 22 charges the first battery 41 or the second battery 42, the output voltage of the solar power generation layer 22 can be adjusted by the voltage adjusting circuit 31 to ensure that the output voltage of the voltage adjusting circuit 31 is greater than the voltage of the battery, and for the adjusted output voltage, the stability of charging the first battery 41 and the second battery 42 can be ensured under the mutual cooperation of the PMIC4 and the processor 33, so as to avoid the situation that the electric quantity of the first battery 41 or the second battery 42 flows backwards.
