Detailed Description
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a color-changing control method applied to a wrist-worn device having an electrochromic device according to an embodiment of the present invention, the method including the following steps:
s101, the wrist-worn device with the electrochromic assembly acquires a color control command.
The wrist-worn device can be specifically a bracelet, a watch, a telephone watch and other devices which can be worn on the wrist.
The electrochromic assembly is an assembly with electrochromic materials, and in this embodiment, the electrochromic assembly may specifically be an assembly such as a watch band, a display screen, and a camera cover film of the wrist-worn device.
The color control instruction may be embodied as a user input instruction, or a self-generated instruction. The color control instruction can specifically regulate whether the color is colorless or a specific color, or change the color according to a certain rule, and the like.
The following describes in detail the manner of acquiring the color control command for a specific shape structure of the electrochromic element in combination with a specific application scenario:
mode 1: the electrochromic assembly is specifically worn by a wrist, and the color control instruction acquisition process comprises:
step one, acquiring a wrist strap color setting parameter input by a user;
determining a color control instruction by utilizing the wrist strap color setting parameters;
wherein the electrochromic component is a wrist strap; the wrist band includes: an electrochromic layer, a transparent conductive layer, and a transparent substrate layer.
The above two steps will be described below in combination for convenience of description.
In the wrist-wearing device, the watchband not only has a fixing function, but also has the leading effect of fashion trend, and the watchband with gorgeous color and comfortable material can greatly improve the interest of consumers in the wrist band product. But the watchband is mainly by silica gel, cladding material at present, and the colour is fixed, and along with the time lapse, consumer's fresh sense also can reduce gradually.
With the development of the flexible screen technology, a scheme is provided for extending the flexible screen to the watchband, so that the color of the watchband is changed. Although the scheme has novel idea, the scheme has the problem of low realizability, and the main reasons include: 1. the flexible screen technology is not completely mature, and the batch, the yield, the bending degree and the like are limited to a certain extent; 2. the flexible screen consumption is big, and the wrist-worn device is sensitive to the consumption, if the watchband part also comprises display module assembly, then can cause very big consumption, leads to user's high frequency to charge, very big influence user experience.
In the embodiment of the invention, the electrochromic component is adopted, the softness is increased by adding the ITO flexible electrodes at the two ends of the electrochromic material in the electrochromic component, and the electrochromic component is connected with a circuit, so that a user can independently define favorite colors through software APP, and different colors are displayed on a watchband; the electrochromic material consumes electricity and does not affect endurance.
Electrochromic materials are generally classified into inorganic and organic types according to the type of the material. Researches show that the organic electrochromic material can realize colorful possibility. In the embodiment of the invention, the color is changed by adopting an organic electrochromic material. The organic electrochromic material has the advantages of low cost, capability of changing color in multiple colors, capability of optimizing performance through molecular design and the like.
But the chemical stability is relatively poor, the bonding force with a substrate material is weak, and the bonding is poor. Therefore, a special laminated structure needs to be designed to be more stable. Fig. 2 is a schematic view of a stacked structure of a high transmittance electrochromic device according to the characteristics of the wrist-worn apparatus in the embodiment of the present invention, where the structure is as follows from left to right: transparent glass (or other transparent substrate material), transparent conductive layer (i.e., electrode), electrochromic layer, transparent conductive layer, transparent glass. Among them, the electrochromic layer may be preferably controlled within 0.08mm thickness to avoid a retardation of color change.
Mode 2: specifically, electrochromic subassembly is the display screen, and the acquisition process of colour control instruction includes:
acquiring an environment image, and determining the safety state of the current use environment by using the environment image;
generating a color control instruction matched with the safety state; wherein the electrochromic component is a display screen of the wrist-worn device;
the display screen includes: the display comprises a glass cover plate, a numerical control layer, an electrochromic layer and a liquid crystal display layer.
For convenience of description, the above two steps will be described in combination.
In the embodiment, in order to effectively protect the user information, the information can be displayed when the current use environment is determined to be safe; and hiding the screen information when the current use environment is determined to be unsafe.
Specifically, an environment image can be collected by the aid of the camera, the environment image is identified, and the safety state of the current use environment is determined. If the multiple human face images are judged to appear, if so, the possibility that the current use environment is peeped can be determined, and the current use environment is determined to be unsafe. At this point, color control instructions corresponding to an environmentally unsafe condition may be generated. Of course, if a secure environment is determined, no action may be required.
Referring to fig. 3, fig. 3 is a schematic view of a display screen hierarchy structure according to an embodiment of the present invention. The electrochromic layer corresponding to the safe environment can be set to be colorless and transparent, and the shop-site electrochromic layer corresponding to the non-safe environment can be set to be opaque (colored or colorless). That is, when the electrochromic layer is opaque, whatever the LCD (liquid crystal display layer, including the TFT layer and other optical fiber portions such as a light-shielding sheet, a resonator sheet, etc.) displays cannot be viewed through the electrochromic layer to the outside. The screen can be effectively hidden.
Mode 3: electrochromic subassembly still can cover the membrane for the camera, and the color control instruction obtains the process, includes:
step one, acquiring camera state information;
generating a color control instruction matched with the camera state information;
wherein, the electrochromic component covers the surface of the camera.
For convenience of description, the above two steps will be described in combination.
Taking a child watch as an example, in order to increase the front camera, a large forehead part is often required to be reserved, which is contrary to the mainstream trend of consumer electronics to continuously increase the screen occupation ratio. In this embodiment, the photographing can be realized by adding a part of electrochromic material inside the LCD, and when the needed camera is used, the electrochromic material changes to transparent color.
Specifically, a hole digging screen/water drop screen technology can be adopted, and an electrochromic array is added to the hole digging part of the LCD. In the electrochromic array, the unit of each electrochromic material can be minimized as much as possible, so that the display principle of the LCD can be simulated to the maximum extent through a control circuit, and the camera can be covered to the maximum extent; when the camera is required to work, similarly, the electrochromic material can be uniformly changed into a transparent state through the control circuit, and the camera can be photographed.
Mode 4: electrochromic subassembly constitutes the heart electrograph and gathers the return circuit, and color control instruction obtains the process, includes:
step one, utilizing an exposed transparent conducting layer in an electrochromic assembly to collect an electrocardiogram;
secondly, determining the health state of the target by utilizing the electrocardiogram;
and step three, generating a color control instruction matched with the target health state according to the corresponding relation between the health state and the color display.
For convenience of description, the above three steps will be described in combination.
Wherein the exposed transparent conductive layer serves as an electrode for electrocardiogram acquisition.
Electrocardiography (ECG or EKG) is a technique that uses an electrocardiograph to record from the body surface the pattern of electrical activity changes produced by the heart during each cardiac cycle.
By means of the expansion circuit, the ECG detection, the electric quantity display or the prompting of the temperature condition of the spare product are realized by using electrochromic materials: a circle of decorative piece made of electrochromic materials is added around an LCD of the wrist-wearing device, and the decorative piece can be two semi-circles or can be in a whole ring shape. As shown in fig. 4a, fig. 4a is a schematic diagram illustrating a position of an electrochromic device according to an embodiment of the present invention.
The principle of ECG is to form a loop through the heart of human body, so that 1-2 electrodes can be disposed on the bottom and 1-2 electrodes can be disposed on the top of the wrist-worn device (see the implementation structure of fig. 4 b), and when the wrist-worn device is used, the hand not wearing the wrist-worn device touches the top electrode to form a loop, thereby generating an electrocardiogram.
Referring to fig. 5, fig. 5 is a schematic diagram illustrating a position of an electrochromic electrode according to an embodiment of the invention. In consideration of the fact that the electrode material needs to be conductive, and therefore occupies a space and causes an overlarge dial, in this embodiment, the electrochromic electrode can be placed in an LCD (liquid crystal display) needs to be perforated) or in an ink screen printing area of the LCD, when the electrochromic electrode is not used, the electrode presents black according to an electrochromic principle and is consistent with surrounding colors, and when an ECG is used, a control instruction for controlling the color of the electrode is generated after a monitoring result is obtained, so that the electrode presents a striking color such as red (abnormal electrocardio) or orange (normal electrocardio) and the like, and is highlighted.
And S102, determining the target optical property of the electrochromic component by using the color control command.
In this embodiment, the optical property to be presented is referred to as a target optical property.
Specifically, the color control command can be analyzed to determine the target optical property of the electrochromic component; the target optical properties include: reflectivity, absorptivity, and transmittance.
That is, the transmittance, absorptance and reflectance. Three parameters can characterize the color condition, such as colorless transparency, colored opacity.
S103, determining a driving voltage corresponding to the target optical property.
Since electrochromism refers to a phenomenon that under the stimulation of external current or potential difference (i.e., an electric field), the chemical valence and chemical components of a compound are reversibly changed, i.e., oxidation or reduction reaction occurs, so that the absorption or reflection spectrum of the compound is changed easily. Under the action of an external electric field, electrons or ions are injected or extracted from the compound A to generate reversible redox reaction, and another compound A-or A + with different structures, optical properties or thermal properties is generated.
Therefore, in the present embodiment, the corresponding relationship between the optical property and the driving voltage can be stored in advance, so that the driving voltage can be determined directly based on the corresponding relationship.
And S104, controlling a driving circuit of the electrochromic component to output a driving voltage so as to change the current optical property of the electrochromic component to the target optical property.
The specific structure of the circuit can be referred to fig. 6, and fig. 6 is a schematic diagram of a driving circuit of an electrochromic device according to an embodiment of the present invention.
The drive circuit provides energy for oxidation-reduction reaction of electrochromic materials in the electrochromic assembly, and different colors have different voltage levels, so that multi-color adjustment is realized.
In practical application, different driving voltages can be periodically output, so that the color state of the electrochromic material can be continuously changed.
In particular, human skin tones may also be simulated and displayed by the electrochromic element to help hide the device, e.g. to help a hearing impaired patient hide a hearing aid.
By applying the method provided by the embodiment of the invention, the wrist-worn device with the electrochromic assembly acquires the color control instruction; determining a target optical property of the electrochromic assembly using the color control command; determining a driving voltage corresponding to the target optical property; and controlling a driving circuit of the electrochromic component to output a driving voltage so as to change the current optical property of the electrochromic component to the target optical property.
Since the electrochromic components exhibit different optical properties when different voltages are applied. Therefore, in the method, after the wrist-worn device with the electrochromic component acquires the control command, the corresponding target optical attribute is determined, then the driving voltage corresponding to the target optical attribute is determined, and the driving circuit is controlled to output the driving voltage. Thus, under the driving voltage, the electrochromic material changes the current optical property into the target optical property. Optical properties refer to transmittance, reflectance and absorbance. In other words, by controlling the output driving voltage in the method, the corresponding color of the electrochromic component in the wrist-wearing device can be changed, and the fashion sense and the decoration are enhanced.
