Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

It should be noted that, if not conflicting, the various features in the embodiments of the present application may be combined with each other, which is within the protection scope of the present application. In addition, while functional block division is performed in a device diagram and logical order is shown in a flowchart, in some cases, the steps shown or described may be performed in a different order than the block division in the device, or in the flowchart. Moreover, the words "first," "second," "third," and the like as used herein do not limit the data and order of execution, but merely distinguish between identical or similar items that have substantially the same function and effect.

Before describing the present application in detail, the terms and terminology involved in the embodiments of the present application will be described, and the terms and terminology involved in the embodiments of the present application are suitable for the following explanation:

(1) Electrochromic refers to a phenomenon that optical properties (reflectivity, transmissivity, absorptivity and the like) of a material change in color stably and reversibly under the action of an applied electric field, and is expressed as reversible changes in color and transparency in appearance. Materials having electrochromic properties are referred to as electrochromic materials, and devices made from electrochromic materials are referred to as electrochromic devices. The electrochromic material has bistable property, and the electrochromic display device made of the electrochromic material does not need a backlight lamp, and after displaying a static image, the display content is not changed, so that power consumption is avoided, and the aim of saving energy is fulfilled. Compared with other displays, the electrochromic device has the advantages of blind angle, high contrast, low manufacturing cost, wide working temperature range, low driving voltage, rich colors and the like, and has great application prospects in the fields of instrument display, outdoor advertisements, static display and the like.

The memory comprises a solid-state memory, and can record or update the current state or fault in real time in a fixed storage area configured internally during operation, and the host can access the information through a port appointed in advance. For a user or administrator, if such information is desired, the port may be invoked by the host to view such information. In some memory product designs, one or more of these information items, important or commonly used, are visually displayed by placing an indicator light or LED screen on the surface of the housing.

Currently, due to lack of visual display of memory status or failure, it is inconvenient to view or manage; or even if such functions and components are present, their operation requires a memory power-up state.

On the one hand, if the memory has no visual display of status or failure, although the user or administrator can call the corresponding port to acquire the information through the host, the method is inconvenient, low in efficiency and easy to miss (such as tens or even millions of disks in a large-scale data center and a cloud computing center), and a certain failed disk is found and confirmed, so that a plurality of steps are needed.

On the other hand, in the design of some memory products, one or more important or common items of information are visually displayed by arranging an indicator lamp or an LED screen on the surface of the shell; however, once powered down, this information is likewise not visible. In some situations, such as power-down maintenance of a data center, fault return to factories, etc., users and staff want to be able to screen and judge the state or fault of a memory in the power-down state, but the prior art still cannot be satisfied.

Based on the above, the embodiment of the application provides a storage device, which improves the state detection efficiency of the storage device.

The following specifically describes the technical scheme of the present application with reference to the drawings of the specification:

referring to fig. 1, fig. 1 is a schematic structural diagram of a storage device according to an embodiment of the present application;

as shown in fig. 1, the storage device 100 includes: a main control module 110, a color change control module 120, and an electrochromic device 130, wherein,

the main control module 110 is connected with the color change control module 120 and is used for monitoring state information generated in the storage device 100 to send a control signal to the color change control module 120 so as to wake up the color change control module 120; wherein the status information includes, but is not limited to: fault information, usage status information, for example: available space information, available capacity information, health index information, last usage time information, bad block number information.

The color change control module 120 is connected with the main control module 110 and the electrochromic device 130, and is used for receiving the control signal sent by the main control module 110, generating a pulse signal, and sending the pulse signal to the electrochromic device 130 so as to control the electrifying voltage and/or electrifying time of the electrochromic device 130;

the electrochromic device 130 is disposed on the housing of the storage device 100, and is connected to the color change control module 120, and is configured to change its display color according to the power-on voltage and/or the power-on time, so as to adjust the display color of the housing of the storage device 100.

Referring to fig. 2 again, fig. 2 is a schematic structural diagram of a memory device according to an embodiment of the present application;

as shown in fig. 2, the storage device 100 is in communication connection with a host in a wired or wireless manner for implementing data interaction, where the storage device 100 may be a storage device such as a mechanical Hard Disk (HDD), a solid state Disk (Solid State Drives, SSD), a mobile Hard Disk, a fixed Hard Disk, and the like, and the storage device is provided with a housing.

Specifically, the storage device 100 includes: a main control module 110, a color change control module 120, an electrochromic device 130, a dynamic memory module 140 and a plurality of flash memories 150.

The main control module 110 is a main controller or an SSD controller, and includes a processor 111, a host interface controller 112, a cache controller 113, a flash memory controller 114, a cache unit 115, and a data codec unit 116.

Specifically, the processor 111 is connected to the host interface controller 112, the cache controller 113 and the flash memory controller 114, where the processor 111 and the host interface controller 112, the cache controller 113 and the flash memory controller 114 may be connected by buses or other manners, and the processor is configured to run nonvolatile software programs, instructions and modules to implement data processing or command processing of the main control module 110.

In the embodiment of the present application, when the storage device 100 operates, the main control module 110 monitors the operation states of all components including the main control module 110, for example: the operating state of one or more of the processor 111, the host interface controller 112, the cache controller 113, the flash memory controller 114, the cache unit, the data codec unit 116, and the flash memory 150 in the main control module 110. When one or more states associated with the color change control module 120 are found to change or change, i.e., a predefined fault or state occurs, the processor 111 sends a hardware reset signal to the color change control unit 121 of the color change control module 120 to wake up the color change control unit 121 of the color change control module 120, for example: the singlechip sends state information or fault information corresponding to the fault to the color change control unit 121, so that the color change control unit 121 enters a working mode after being awakened, receives the state information or fault information sent by the processor 111, and sends a pulse signal to the signal conversion unit 122 according to the state information or fault information so as to control the electrifying voltage and/or electrifying time of the transparent conductive layer of the electrochromic device 130, so that the shell of the storage device is partially or completely changed.

Specifically, the host interface controller 112 is connected to the processor 111, the cache controller 113, and the flash memory controller 114, and is used for controlling interfaces for interfacing with a host, where the interfaces are used for receiving data sent by the host, or receiving data sent by the processor 111, and implementing data transmission between the host and the processor 111, where the interfaces include SATA-2 interfaces, SATA-3 interfaces, SAS interfaces, MSATA interfaces, PCI-E interfaces, NGFF interfaces, CFast interfaces, SFF-8639 interfaces, and interfaces of m.2nvme/SATA protocols.

Specifically, the cache controller 113 is connected to the processor 111, the cache unit 115, and the dynamic storage module 140, and is configured to control data in the cache unit 115, for example: and reading or writing data sent by the host.

Specifically, the flash memory controller 114 is connected to the processor 111, the cache controller 113, the data codec unit 116, and the plurality of flash memories 150, and is configured to access the plurality of flash memories 150 at the back end, and manage various parameters and data I/O of the flash memories 150; or, the interface and the protocol for providing access are used for realizing a corresponding SAS/SATA target protocol end or NVMe protocol end, acquiring an I/O instruction sent by the host, decoding and generating an internal private data result, and waiting for execution; or for taking care of the core processing of the flash translation layer (Flash translation layer, FTL). The flash controller 114 uses flash commands conforming to the ONFI and Toggle standards of the flash memory to manage the reading and writing of data from the cache memory to the flash memory. The flash controller is connected and communicates with the flash memory, and from a single flash perspective, a Die/LUN is the basic unit of flash command execution.

Specifically, the buffer unit 115 is mainly used for buffering a read/write command sent by a host and read data or write data obtained from the flash memory 150 according to the read/write command sent by the host.

Specifically, the data encoding and decoding unit 116 includes an ECC module for performing ECC check. It can be appreciated that since the flash memory stores an error rate naturally, for the correctness of data, an ECC check protection should be added to the original data during the data writing operation, which is an encoding process. When reading data, it is also necessary to detect and correct errors by decoding, and if the number of bits in error exceeds the ECC error correction capability, the data is uploaded to the host in a "non-error-correctable" form. The ECC encoding and decoding process is performed by the data codec unit 116. ECC algorithms in SSDs are mainly BCH and LDPC, which are increasingly becoming the mainstream.

The color change control module 120 is connected to the processor 111 and the electrochromic device 130, and is configured to receive a control signal sent by the processor 111, so as to control a display color of the electrochromic device 130.

The color change control module 120 includes: the color change control unit 121 and the signal conversion unit 122, the color change control module 121 is connected to the signal conversion unit 122, and the color change control unit 121 is configured to receive the control signal sent by the processor 111, generate a pulse signal, and send the pulse signal to the signal conversion unit 122, so that the signal conversion unit 122 controls the display color of the electrochromic device 130 according to the pulse signal.

Specifically, the color change control unit 121 is connected to the processor 111 of the main control module 110, and is configured to receive a control signal sent by the processor 111 of the main control module 110 and generate a pulse signal;

specifically, the signal conversion unit 122 is connected to the color change control unit 121 and the electrochromic device 130, and is configured to receive the pulse signal sent by the color change control unit 121, and control the power-on voltage and/or the power-on time of the electrochromic device 130 according to the pulse signal, so as to control the display color of the electrochromic device 130. The signal conversion unit is used for controlling the energizing voltage and/or energizing time of the transparent conductive layer so as to enable the electrochromic device to generate color change.

In the embodiment of the present application, the color-change control unit 121 includes a single-chip microcomputer, for example: the AT89S52 single-chip microcomputer is configured to receive a control signal sent by the processor 111 of the main control module 110, so as to output a pulse signal, where the pulse signal includes a pulse width modulation signal (Pulse Width Modulation, PWM), and the signal conversion unit 122 includes a digital-to-analog converter or an analog filter, where the digital-to-analog converter or the analog filter converts the pulse width modulation signal output by the single-chip microcomputer into a continuous voltage value.

In this embodiment of the present application, after the corresponding external color display control operation is performed, the color change control unit 121, for example, a singlechip, enters the power-down mode or enters the sleep mode again by setting a register, and when entering the power-down mode, the power consumption can be reduced to below 0.1 μa due to the fact that the power consumption is reduced to 2mA when entering the sleep mode, and the power consumption is different by tens of thousands times. It will be appreciated that since the external color control does not work frequently, the color change control unit is preferably controlled to enter the power-down mode after adjusting the display color of the housing of the storage device. In the embodiment of the present application, the color change control unit 121 includes, but is not limited to, a processing unit with data processing capability, such as a single-chip microcomputer, a microprocessor, a central processing unit, and the like. Wherein, the singlechip includes 51 singlechip.

The electrochromic device 130 is disposed on the housing of the storage device, may be an integral housing or a partial housing, and the electrochromic device 130 may change its own color according to status information or fault information of the current status of the operation of the storage device 100, so as to change the color of the housing of the storage device 100.

It will be appreciated that since the electrochromic device 130 is reversible, when one or more states associated with the color change control module 120 are reversible, i.e., reversible faults, such as: the working temperature is too high, the available capacity is too low, and the like, so that the possible fault state can be restored to the normal state along with the operation of the storage device, and at the moment, the color change of the shell of the storage device also changes reversely, and the processing process is similar to that of the forward change. Specifically, the main control module, for example: the main controller or the SSD controller sends out a hardware reset signal to wake up the color change control unit 121 of the color change control module 120, and sends state information or fault information corresponding to one or more states which are reversely changed to the color change control unit 121; after the color change control unit 121 is awakened, it enters a normal operation mode, receives fault information or status information sent by the processor 111, determines external color control according to the fault information or status information, and outputs a pulse signal, and the signal conversion unit 122, for example: a digital-to-analog converter (DAC) or an analog filter, according to the color change control unit 121, for example: the pulse width modulation output (PWM) of the single chip microcomputer controls the energizing voltage and energizing time of the transparent conductive layer in the electrochromic device 130 such that the housing color of the memory device changes. After the singlechip performs the corresponding external color control operation, the power-down mode is entered again through setting a register.

It will be appreciated that if the above state does not reverse during operation of the memory device or after a restart, the housing color of the memory device will remain, depending on the characteristics of the electrochromic material.

It should be noted that there is another type of status related to the storage device, which cannot implement self-inversion, such as bad block proportion exceeding a threshold value, wear life reaching a dangerous period, and the like. At this time, after the color of the shell corresponding to the state or fault is changed, the self-inversion cannot be realized, and even if the storage equipment is powered down, the storage equipment is kept all the time, so that the classification, screening and other works of the storage can be realized by relevant personnel of users or factories. It can be understood that if the storage device with irreversible failure is maintained or returned to the factory for maintenance, the corresponding failure problem is solved, and the shell color of the storage device can be reversely changed into the original normal color through an external circuit or an internal interface instruction of the storage device.

Specifically, referring to fig. 3 again, fig. 3 is a schematic structural diagram of an electrochromic device according to an embodiment of the present application;

as shown in fig. 3, the electrochromic device includes: a transparent protective layer, a transparent conductive layer, an electrochromic layer, an electrolyte layer, an ion storage layer, and a substrate layer.

Wherein, the transparent protective layer, namely the transparent insulating protective layer, is arranged on the uppermost layer or the outermost layer of the electrochromic device;

the substrate layer is disposed on the lowermost layer or the bottommost layer of the electrochromic device, and may be a colored material or a transparent material, but black or a material close to black is not used in view of contrast enhancement.

The transparent conducting layer is arranged below the transparent protective layer and above the substrate layer, and the electrochromic device comprises two transparent conducting layers, wherein one transparent conducting layer is grounded, each transparent conducting layer at least has two points, namely a good electronic conductor and high light transmittance. Two common transparent conductive glasses, fluorine (F) doped tin oxide (SnO ₂ ) A transparent conductive layer serving as conductive glass, abbreviated as FTO glass; tin doped indium oxide (In ₂ O ₃ ) A transparent conductive layer serving as conductive glass, namely ITO glass;

and the electrochromic layer is arranged below the upper transparent conductive layer, wherein the electrochromic layer is made of electrochromic materials such as transition metal oxide and organic conductive polymer. Under the action of an external electric field, charge transfer occurs, and the performance of the electrochromic device is mainly determined by the electrochromic layer.

And the electrolyte layer is arranged in the middle of the electrochromic device and is used for providing a transmission channel of ions for electrochromic effect, the complex of polyethylene oxide and alkali metal salt has good ion conduction characteristics, and the polymer electrolyte is an excellent ion transmission layer substance.

And the ion storage layer is arranged below the electrolyte layer and is used for storing and providing ions required by the electrochromic material. Under the action of an external electric field, releasing ions to be injected into the electrochromic layer; ions ejected from the electrochromic layer are stored when a reverse electric field is applied.

It can be understood that the electrochromic layer and the ion storage layer undergo opposite oxidation or reduction processes under the action of an electric field, namely, the electrochromic layer undergoes oxidation reaction and the ion storage layer undergoes reduction reaction, so that after the display color of the shell of the storage device is changed, the singlechip can be powered down, and the display color of the shell can still be maintained after the storage device is powered down.

The dynamic memory module 140 is used as a memory unit of the main control module 110, and is used for storing data of the main control module, or is used for loading programs and data for the processor 111 of the main control module 110 to directly run and operate. In an embodiment of the present application, the dynamic memory module 140 includes dynamic random access memory (Dynamic Random Access Memory, DRAM).

The Flash memory 150, which is a storage medium of the storage device 100, is also called a Flash memory, a Flash memory, or Flash particles, is a type of a storage device, is a nonvolatile memory, and can store data for a long time even without current supply, and has storage characteristics equivalent to a hard disk, so that the Flash memory 150 becomes a base of storage media of various portable digital devices.

In some embodiments, the main control module further includes a data converter (not shown) connected to the processor and the flash memory controller, respectively, for converting binary data into hexadecimal data and vice versa. Specifically, when the flash memory controller writes data to the flash memory, binary data to be written is converted into hexadecimal data by the data converter, and then written to the flash memory. When the flash memory controller reads data from the flash memory medium, hexadecimal data stored in the flash memory is converted into binary data by the data converter, and then the converted data is read from the binary data page register. The data converter may include a binary data register and a hexadecimal data register, among others. Binary data registers may be used to hold data converted from hexadecimal to binary, and hexadecimal data registers may be used to hold data converted from binary to hexadecimal.

In the embodiment of the application, the storage device comprises a main control module, a color change control module and an electrochromic device, wherein the main control module is connected with the color change control module and is used for monitoring fault information in the storage device so as to send a control signal to the color change control module and wake up the color change control module; the color change control module is connected with the main control module and the electrochromic device and is used for receiving the control signal sent by the main control module, generating a pulse signal and sending the pulse signal to the electrochromic device so as to control the electrifying voltage and/or electrifying time of the electrochromic device; the electrochromic device is arranged on the shell of the storage device, is connected with the color change control module and is used for changing the display color of the electrochromic device according to the energizing voltage and/or the energizing time, and then adjusting the display color of the shell of the storage device.

Referring to fig. 4 again, fig. 4 is a flow chart of a control method of a storage device according to an embodiment of the present application;

as shown in fig. 4, the control method of the storage device includes:

step S401: monitoring status information occurring in the storage device;

specifically, the storage device includes a main control module, and the main control module monitors the operation states of all components including the main control module, for example: the running states of one or more of the processor, the host interface controller, the cache controller, the flash memory controller, the cache unit, the data encoding and decoding unit and the flash memory in the main control module include, but are not limited to: fault information, usage status information, for example: available space information, available capacity information, health index information, last usage time information, bad block number information, for example: and if a certain component fails, sending a control signal to the color change control module according to the state information corresponding to the failure.

Step S402: and sending a control signal to the color change control module according to the state information so as to wake up the color change control module to enter a normal working mode, and further controlling the electrifying voltage and/or electrifying time of the electrochromic device so as to adjust the display color of the shell of the storage device.

Specifically, a control signal is sent to the color change control module according to the state information to wake up the color change module to enter a normal working mode, and then the electrifying voltage and/or electrifying time of the electrochromic device are controlled to adjust the display color of the shell of the storage device.

For example: when it is found that one or more states associated with the colour change control module change or change, i.e. a predefined state information occurs, the processor sends a hardware reset signal to the colour change control unit of the colour change control module to wake up the colour change control unit of the colour change control module, for example: the single chip microcomputer sends state information or fault information corresponding to the faults to the color change control unit, so that the color change control unit enters a working mode after being awakened, receives the state information or the fault information sent by the processor, and sends pulse signals to the signal conversion unit according to the state information or the fault information so as to control the electrifying voltage and/or electrifying time of the transparent conductive layer of the electrochromic device, so that the shell of the storage device is partially or completely color changed.

In this embodiment of the present application, the color change control module includes a color change control unit and a signal conversion unit, and according to state information, sends a control signal to the color change control module, including:

determining whether the status information belongs to predefined status information, wherein the status information includes, but is not limited to: fault information, usage status information, for example: available space information, available capacity information, health index information, latest use time information and bad block number information;

if so, a control signal is sent to the color change control unit so that the color change control unit generates a pulse signal, and a voltage signal is generated by the signal conversion unit based on the pulse signal so as to control the energizing voltage and/or energizing time of the electrochromic device, wherein the control signal comprises a hardware reset signal and a digital signal corresponding to the state information.

Specifically, a first state information set is predefined, wherein the first failure information set includes state information related to the electrochromic device, that is, any one of the state information included in the first state information set is used for changing the color of the electrochromic device. If the processor of the main control module judges whether certain state information belongs to predefined state information, namely, judges whether certain state information belongs to a first state information set, if yes, the processor determines that the state information belongs to the predefined state information, the processor sends a control signal to a color change control unit of the color change control module, wherein the control signal comprises a hardware reset signal and a digital signal corresponding to the state information, the hardware reset signal is used for waking up the color change control unit in the color change control module, the digital signal corresponding to the state information is used for enabling the color change control unit to output a calculation result according to a prefabricated program and sends the calculation result to a signal conversion unit, so that the signal conversion unit converts the calculation result into a voltage signal and applies the voltage signal to a transparent conductive layer of the electrochromic device, and the electrochromic device is enabled to generate color change.

Specifically, referring to fig. 5 again, fig. 5 is an overall flow chart of a control method of a storage device according to an embodiment of the present application;

the control method of the storage device is applied to the storage device in the embodiment.

As shown in fig. 5, the overall flow of the control method of the storage device includes:

step S501: the main control module monitors the state change of the storage device;

specifically, the processor of the main control module monitors the operation states of all components of the storage device, for example: the host computer comprises a main control module, a processor, a host interface controller, a cache controller, a flash memory controller, a cache unit, a data encoding and decoding unit and one or more running states of the flash memory.

If a certain state change belongs to predefined state information, the step S502 is entered;

step S502: the main control module sends a hardware reset signal to the color change control module to wake up the color change control module to enter a normal working mode;

specifically, the processor of the main control module sends a hardware reset signal to the color change control unit of the color change control module to wake up the color change control unit and the signal conversion unit of the color change control module, so that the color change control module enters a normal working mode;

Step S503: the main control module sends a digital signal corresponding to the state information to the color change control module;

specifically, the processor of the main control module sends a digital signal corresponding to the state information to the color change control unit of the color change control module, so that the color change control unit receives the digital signal corresponding to the state information.

Step S504: the color change control module outputs a calculation result based on a preset program according to the digital signal corresponding to the state information;

specifically, after the color change control module receives the digital signal corresponding to the state information, the digital signal corresponding to the state information is calculated based on a preset program according to the digital signal corresponding to the state information, so as to output a calculation result.

For example: the state change includes fault information, if there is only one fault definition, then a bit

binary information

0 or 1 is used to indicate that the fault occurs, 0 is no fault, otherwise there is a fault. When a fault occurs, 8'b00000001 (complement 8 bits) is input, indicating that a fault occurs, and the output is 8' b01111111.

Step S505: the signal conversion unit converts the calculation result into a voltage signal and applies the voltage signal to the electrochromic device so as to cause the electrochromic device to generate color change;

specifically, the color change control unit sends the calculation result to the signal conversion unit, through the signal conversion unit, for example: a digital-to-analog converter converting a digital signal into a voltage signal, for example: is converted to +5v voltage and applied to the transparent conductive layer of the electrochromic device to cause the electrochromic device to change color, which in turn causes the housing of the memory device to change color.

Step S506: the color change control unit of the color change control module enters a power-down mode;

specifically, after the shell of the storage device generates color change, the register is set to enable the color change control unit of the color change control module to enter a power-down mode, so that the electrochromic device still keeps displaying in a power-down state.

In an embodiment of the present application, by providing a method for controlling a storage device, the method is applied to the storage device of the foregoing embodiment, and the method includes: monitoring fault information occurring in the storage device; and sending a control signal to the color change control module according to the state information so as to wake up the color change control module to enter a normal working mode, and further controlling the electrifying voltage and/or electrifying time of the electrochromic device so as to adjust the display color of the shell of the storage device.

By monitoring the state change occurring in the storage device to control the energizing voltage and/or energizing time of the electrochromic device to adjust the display color of the housing of the storage device, the state detection efficiency of the storage device can be improved.

In an embodiment of the present application, a memory device includes at least two electrochromic devices, each electrochromic device including: the device comprises a transparent protective layer, a transparent conductive layer, an electrochromic layer, an electrolyte layer, an ion storage layer and a substrate layer, wherein at least two electrochromic devices are in a superposition structure.

It will be appreciated that colour rendering is largely dependent on the choice of electrochromic material, although polychromatic variation can be achieved by controlling voltage, and power-on time, contrast is not strong, and sometimes is difficult to distinguish; some metal organic complexes, such as phthalocyanine and lutetium (Lu) complex, the electrochromic range can be changed among red, green, blue and purple, but the problem that the multicolor change range is small, and even the contrast ratio among some colors is not strong and is difficult to distinguish still exists.

At present, a wide color switching problem is difficult to realize by using one electrochromic material, so that the memory device has more excellent color changing performance, such as higher color purity and wider color range by using a multi-electrochromic stacking mode, such as stacking three electrochromic devices respectively corresponding to three primary colors, so that richer color expression is realized.

Specifically, referring to fig. 6 again, fig. 6 is a schematic diagram of a stacked structure of electrochromic devices according to an embodiment of the present disclosure;

as shown in fig. 6, a superimposed structure of two electrochromic devices is shown, wherein each electrochromic device corresponds to a different color, and each electrochromic device includes: the device comprises a transparent protective layer, a transparent conductive layer, an electrochromic layer, an electrolyte layer and an ion storage layer, wherein the two electrochromic devices share one substrate layer.

In the embodiment of the application, at least two electrochromic devices are in a superposition structure so as to realize superposition of colors, and therefore, the shell of the storage device presents a better display effect.

It will be appreciated that, as the integration of solid state storage is now higher and higher, the required volume and circuit area are smaller and smaller, if a superposition of multiple electrochromic devices is used, the use of one color change control module for each electrochromic device increases the cost overhead, and in some cases the circuit area and power consumption are limited.

Therefore, the embodiment of the application further provides a storage device, and the data distributor is added to realize one color change control module to control at least two electrochromic devices.

Wherein, the level shifter adjusts the output voltage range to [ -v ] through an external power supply _out ,v _out ](e.g., [ -5V, 5V)]) The external power supply comprises a negative power supply for outputting negative voltage.

It will be appreciated that since digital to analog converters generally only enable digital to positive voltage conversion of digital signals, for example: 0-5V, so, in order to achieve a reversal of the current direction, such as a range of [ -5V,5V ], a level shifter is used to amplify the positive voltage, for example: amplifying 0-5V to 0-10V, and adding a reverse compensation of-5V via external power supply to make the final output voltage fall in the interval of [ -5V,5V ].

For example: for part (a) of fig. 14, one number corresponds to seven number components, two numbers correspond to fourteen number components, one punctuation mark is added, 15 electrochromic devices are needed to perform display processing in total, and control is needed through a 1:16 data Distributor (DMUX), wherein one electrochromic device corresponds to one number component or one punctuation mark of one number, so that display of digital information of two numbers and one punctuation mark is achieved, and one number is displayed by seven number components.
