Referring to fig. 4, the electrochromic cell may include two conductive layers stacked on each other, and a color-changing layer, an electrolyte layer, and an ion storage layer disposed between the two conductive layers.
The conductive layer may be a transparent conductive layer, and has excellent conductivity and good optical transmittance. The transparent conductive layer can be Indium Tin Oxide (ITO) or tin oxide (SnO)2) And oxidation ofTin Antimony (ATO).
The color-changing layer is a core layer of the electrochromic unit and is also a generation layer of color-changing reaction.

The ion storage layer plays a role in storing charges in the electrochromic unit, namely corresponding counter ions are stored when the material of the electrochromic layer undergoes an oxidation-reduction reaction, so that the charge balance of the whole electrochromic unit is ensured.
As shown in fig. 5, when a certain voltage is applied between the two transparent conductive layers, the material of the color-changing layer of the electrochromic cell undergoes an oxidation-reduction reaction under the action of the voltage, thereby undergoing a color change.

When the voltage applied between the two transparent conductive layers is changed from 0V to 1.2V, the electrochromic cell may be changed from white to black. When the voltage applied between the two transparent conductive layers is changed from 1.2V to-0.2V, the electrochromic cell may change from black to white, and so on.
When the fingerprint identification module 15 is in an idle state (i.e., a non-operating state), the electrochromic device 16 may display the same color as the adhesive layer 113, so that the color of the electrochromic device 16 is consistent with the color of the entire electronic device 10. When detecting that need start fingerprint identification module 15 collection fingerprint, electrochromic subassembly 16 can show the colour different with adhesion layer 113 to indicate the regional position of fingerprint identification.
When carrying out the fingerprint unblock, the user can see through apron 111 that electrochromic subassembly 16 shows the colour different with the organism, and then can input fingerprint information in the position area that apron 111 corresponds to electronic equipment 10 passes through electrochromic subassembly 16 and apron 111 collection user's fingerprint in proper order through fingerprint identification module 15, and carries out identification processing to this user's fingerprint, in order to be used for carrying out the unblock to 10 electronic equipment's screen.

One side of the cover plate 211 close to the fingerprint identification module 25 is provided with a groove 2111 extending to the outside of the electronic device 10, and the electrochromic component 26 is arranged in the groove 2111.
Fingerprint identification module 25 is located electrochromic subassembly 26 below, for example, fingerprint identification module 25 is located directly below electrochromic subassembly 26. The electrochromic element 26 may completely cover the fingerprint identification module 25.
When the fingerprint identification module 25 is in the idle state, the electrochromic device 26 may display the same color as the adhesion layer 213, so that the color of the electrochromic device 26 is consistent with the color of the whole electronic device 10.

Therefore, a predetermined voltage is required to be supplied to the electrochromic device.
The preset voltage can be preset, and the color of the electrochromic component can be distinguished from the original color of the electrochromic component after the voltage is applied.
204. The electronic equipment controls the electrochromic component to display a color corresponding to the preset voltage based on the preset voltage, wherein the color is different from the original color of the electrochromic component.
Specifically, due to the physical characteristics of the dot-to-color change composition, different colors can be displayed and different transparencies can be achieved by applying different voltages.
205. Electronic equipment passes through the fingerprint information of fingerprint identification module collection user input.
Specifically, the user can be under electrochromic subassembly's colour suggestion, accurately at the regional fingerprint information of fingerprint identification input to carry out fingerprint collection by the fingerprint identification module.
206. The electronic equipment verifies the fingerprint information and judges whether the fingerprint information passes the verification; if yes, go to step 207, otherwise go to step 201.
In practical application, need prestore sample fingerprint among the electronic equipment to fingerprint information based on this sample fingerprint is gathered to the fingerprint identification module carries out the check-up.
207. The electronic device unlocks the screen and stops providing the preset voltage to the electrochromic assembly so that the electrochromic assembly restores the original color.
Specifically, after the screen is successfully unlocked, the electrochromic assembly is not required to prompt the fingerprint identification area. Therefore, the supply of the preset voltage to the electrochromic component can be stopped, so that the electrochromic component restores the original color and the integrity of the whole machine is maintained.
Referring to fig. 10, when the electronic device is in the screen-locking state, the back of the body is black, and the corresponding rear fingerprint identification area is also black, that is, the electrochromic component currently covering the fingerprint identification module is black. After receiving the fingerprint collection instruction, electronic equipment can apply preset voltage to the electrochromic subassembly that covers on the fingerprint identification module to make electrochromic subassembly's colour become red by black. Then, the user can be based on the suggestion in red region, here input fingerprint information to fingerprint identification module collection fingerprint carries out fingerprint identification and verifies. After the fingerprint verification is passed, the screen locking can be released. At this time, the electronic device stops applying the preset voltage to the electrochromic assembly, the color of the electrochromic assembly is reversibly changed, and the current red color is restored to the original black color.
Therefore, according to the information reminding method provided by the embodiment of the application, the color-changing material is added between the cover plate and the fingerprint identification module, and when the cover plate is unlocked or not unlocked, the color of the color-changing material is consistent with that of the rear cover of the electronic device. When the electronic equipment is detected to be unlocked through fingerprints, the color-changing material is changed into a color inconsistent with the color of the rear cover of the electronic equipment, so that the position of the fingerprint identification area is prompted, and a user can conveniently input fingerprint information in the fingerprint identification area to unlock the screen. The position of fingerprint identification area is reminded to this scheme accessible electrochromic subassembly, and need not to do the recess design in apron department, has promoted the wholeness of complete machine.
