That is, the second color-changing display area 3-3 may entirely cover other areas except the display area in the electronic ink screen, or may partially cover the other areas, which is not specifically limited herein. In order to avoid shielding of the first color-changing display area 3-2 on commodity information displayed by the electronic ink screen, the first color-changing display area 3-2 can be controlled to be in a transparent state when the commodity information is required to be displayed, the first color-changing display area 3-2 can display other colors or patterns when the commodity information is not displayed, and the second color-changing display area 3-3 covers other areas except the ink screen display area, so that the front face of the electronic price tag can display colors or patterns appointed by a user by changing the color state or pattern state of the second color-changing display area 3-3.
The second flexible circuit board 3-1 is electrically connected with the control circuit board and is used for receiving a second display instruction sent by the control circuit board, wherein the second display instruction can comprise a display instruction for controlling the first color-changing display area and a display instruction for controlling the second color-changing display area, the second color-changing display area adjusts the color or pattern state according to the second display instruction so that the front surface of the electronic price tag presents the color or pattern appointed by a user, and the first color-changing display area is in a transparent state according to the second display instruction.
In the embodiment, the structure of the color-changing device is designed according to actual needs, and an optional implementation mode is that the first color-changing display area is hollowed, namely the color-changing device comprises a second flexible circuit board, a hollowed area and a second color-changing display area surrounding the hollowed area, wherein after the color-changing device is arranged above the electronic ink screen, the hollowed area is located right above the display area of the electronic ink screen, the coverage area of the hollowed area is larger than or equal to the coverage area of the display area of the electronic ink screen, the coverage area of the hollowed area is optionally the vertical projection area of the hollowed area on the electronic ink screen, the second color-changing display area is located right above other areas except the display area in the electronic ink screen, the coverage area of the second color-changing display area is smaller than or equal to the coverage area of the other areas, and the second flexible circuit board is electrically connected with the control circuit board and is used for receiving a second display instruction sent by the control circuit board so that the second color-changing display area can conveniently adjust the color state according to the second color-changing display instruction.
In another alternative implementation scheme, a first color-changing display area in the color-changing device is replaced by a transparent component, namely the color-changing device comprises a second flexible circuit board, the transparent component and a second color-changing display area surrounding the transparent component, wherein after the color-changing device is installed above the electronic ink screen, the transparent component is located right above the display area covering the electronic ink screen, the coverage area of the transparent component is larger than or equal to the coverage area of the display area of the electronic ink screen, the coverage area of the transparent component is optionally the vertically projected area of the transparent component on the electronic ink screen, the second color-changing display area is located right above the other areas except the display area in the electronic ink screen, the area of the second color-changing display area is smaller than or equal to the coverage area of the other areas, and the second flexible circuit board is electrically connected with the control circuit board and is used for receiving a second display instruction sent by the control circuit board so that the second color-changing display area can adjust the color state according to the second display instruction.
It should be noted that, for the case that the color-changing device is mounted on the inner surface or the outer surface of the casing, because there is no shielding problem, the color-changing device can adopt a structure in which the first color-changing display area and the second color-changing display area exist simultaneously, so long as the first color-changing display area and the second color-changing display area are ensured to display the same color.
For the purpose of describing the color change device 3 in detail, the first/second color change display regions of the color change device will be described. Exemplary, referring to fig. 4, a schematic structural diagram of the first/second color-changing display region is shown. The first/second color-changing display area comprises five layers, namely a first transparent substrate 4-1, a first transparent conductive layer 4-2, a bistable or multistable display layer 4-3, a second transparent conductive layer 4-4 and a second transparent substrate 4-5 from top to bottom.
Wherein the first transparent conductive layer 4-2 is located above the bistable or multistable display layer 4-3, and is used for driving an upper electrode of an electric field;
A second transparent conductive layer 4-4 positioned below the bistable or multistable display layer 4-3 for driving a lower electrode of an electric field;
The bistable or multistable display layer 4-3 is used for displaying different color states or pattern states according to different applied electric fields, namely, the bistable or multistable display layer 4-3 displays different color states or pattern states by adjusting the electric field between the first transparent conductive layer 4-2 and the second transparent conductive layer 4-4. For example, the bistable or multistable display layer 4-3 may have four selectable color states, defined as A, B, C and D, respectively, which may be switched and displayed by varying the electric field between the first transparent conductive layer 4-2 and the second transparent conductive layer 4-4. For four colors A, B, C, D, respectively coded into 00, 01, 10 and 11, corresponding to four different voltages in sequence, the codes are digital IDs in four states, and the electronic price tag control system can realize the transmission of instructions through retrieval and calling. Meanwhile, by continuously switching between various colored states, a flickering effect can be achieved, visually appearing as a dynamic display of colors and patterns.
Alternatively, the voltages corresponding to the different color states may be seen in table 1.
TABLE 1
| Color state | Encoding | Voltage (V) |
| A | 00 | +15V |
| B | 01 | +5V |
| C | 10 | -5V |
| D | 11 | -15V |
It will be appreciated that if the user does not specify a color state, the color shifting device defaults to a transparent state, i.e., the first/second color shifting regions do not display a color or pattern. The subsequent user can control the electronic price tag to switch between the colored state and the transparent state according to the requirement.

And the second transparent substrate 4-5 is positioned below the second transparent conductive layer 4-4 and is used for bearing and protecting the bistable or multistable display layer, the first transparent conductive layer and the second transparent conductive layer.
Further, other components of the electronic price tag will be further described.
In the embodiment of the utility model, the energy storage battery is a secondary battery, wherein the secondary battery is a battery which can be continuously used by activating an active material in a charging mode after the battery is discharged. I.e. the energy storage battery is a rechargeable battery. For this case, in order to be able to guarantee the charging of the energy storage battery, at least one solar membrane is also provided in the electronic price tag, optionally the solar membrane may be mounted at the bottom or at the upper part of the color-changing device. Specifically, the solar membrane is mounted above or at the bottom of the second color-changing display area of the color-changing device. When the solar energy membrane is realized, the shape of the solar energy membrane can be customized according to the range of the second color-changing display area of the color-changing device, so that the customized solar energy membrane can be just partially covered on the second color-changing display area or just at the bottom of the second color-changing display area after being installed. In addition, the solar membrane can be arranged at the inner edge of the second color-changing display area of the color-changing device, for example, the solar membrane is arranged between the first color-changing display area of the color-changing device and the second color-changing display area, so long as the solar membrane is ensured not to shade the display area of the ink screen.
After the solar membrane is installed according to any installation mode, the solar membrane can be electrically connected with the control circuit board, and then the energy storage battery is charged through the control circuit board. For an example, a schematic view of the structure of an electronic price tag with two solar membranes 7 mounted thereon is shown in fig. 5.
It should be noted that, for the case that the solar membrane is installed at the bottom of the color-changing device, in order to ensure that the solar membrane can convert solar energy into electric energy, when charging is required, the second color-changing device of the color-changing assembly needs to be switched from a colored state to a transparent state.
In an alternative implementation, the energy storage battery can also be provided directly as a primary battery, i.e. as a battery which cannot be charged.
In yet another alternative implementation, the energy storage battery is provided as a rechargeable secondary battery, while one primary battery is provided as an alternative. The primary battery can be arranged at the bottom, the upper part or the side edge of the control circuit board and is used for supplying power to the electronic price tag when the solar membrane cannot charge the energy storage battery and the electric quantity of the energy storage battery is lower than a preset threshold value. Therefore, the electronic price tag can be ensured not to stop working due to the lack of electric quantity.
Further, in order to better introduce the electronic price tag, the functional modules included in the control circuit board in the electronic price tag are explained.
First, the control circuit board comprises a series-parallel control circuit module, which is used for carrying out series connection or parallel connection on electric energy converted by the solar energy membrane when the solar energy membrane is more than or equal to two. It should be noted that the preferred embodiment is parallel connection.
Further, the control circuit board also comprises an energy management module, a microcontroller module, a color changing device controller and a near field coupling module.
The energy management module is respectively and electrically connected with the series-parallel control circuit module and the energy storage battery, and can receive the electric energy converted by the solar membrane transmitted by the series-parallel control circuit module and store the electric energy converted by the solar membrane into the energy storage battery. This is the process of charging the energy storage battery.
In addition, the energy management module is electrically connected with the microcontroller module and can also be used for managing the discharging process of the energy storage battery. When the color-changing device and the electronic ink screen are used for brushing the screen or the electric energy consumption is required, the microcontroller module is used for carrying out instruction receiving and transmitting, the required energy is provided by the energy management module, and particularly, the energy management module is used for controlling the energy storage battery to output electric quantity and providing required current and voltage for the microcontroller module, so that the discharging process of the energy storage battery is realized.
In order to further explain the charge and discharge process, a scene where the electronic price tag is located is described. When the electronic price tag is in a standby state, the power consumption of the whole system is very low, and the energy management module is used for providing the required electric quantity for the electronic price tag by controlling the electric energy output by the energy storage battery. Taking the actual use scene of the electronic price tag in a shop as an example, when the shop is in business, the shop is in an illumination environment, at the moment, the solar membrane collects light energy and converts the light energy into electric energy, the energy storage battery is charged through the energy management module, and the power consumption of the whole electronic price tag mainly comes from a color changing device, a screen brushing process of the electronic ink screen and a standby process of the electronic price tag. After business is finished, the shop turns off the light source in the shop, at the moment, the solar membrane can not charge the energy storage battery, and the power consumption of the electronic price tag mainly comes from the system standby process. In order to realize self-supply of energy of the electronic price tag, the solar battery is required to collect enough energy and store the energy into the energy storage battery under the condition of light, namely the stored energy needs to at least reach all the energy consumed by the electronic price tag in business hours and non-business hours within 24 hours. The solar membrane adopted by the utility model is a solar cell suitable for indoor illumination, and preferably a perovskite solar cell.
In the embodiment of the utility model, a microcontroller module in a control circuit board is electrically connected with a first flexible circuit board of the electronic ink screen and is used for generating the first display instruction (namely, a commodity information display instruction) according to commodity information to be displayed, which is sent by a server, and sending the first display instruction to the first flexible circuit board of the electronic ink screen so that the first flexible circuit board can forward the first display instruction to the driving chip;
