Description
Technical Field
The invention relates to the technical field of electrochromic device color change response time detection, in particular to a method and a device for detecting electrochromic device color change response time and a computer readable storage medium.
Background
Electrochromic devices have begun to be increasingly used, such as exterior wall glass of buildings, color-changing housings for electronic devices, and the like. Among them, several most important index tests of electrochromic devices such as response time, color change efficiency, etc. are mainly tested and analyzed by transmittance change of devices in academic and industrial fields. Taking the response time as an example, the response time of an electrochromic device is roughly defined in terms of the difference between the peak transmittance and the valley transmittance.
The test solutions based on transmittance changes are only applicable to transparent devices, but are not applicable if there are other opaque films or light transmitting non-uniform media, such as electrochromic devices and combined structures with textured films, frosted glass, etc. as substrates. Under the condition, the performance of the product to be monitored can be tested only at the middle stage of the manufacturing process and when the electrochromic device is not attached with other film layers, the performance test of a semi-finished product is carried out, and the test of the finished product is useless.
Moreover, the optical performance of the semi-finished product cannot represent the real use scene of the electrochromic device (after the electrochromic device is matched with other film layers, the overall color effect of the electrochromic device changes), so that the optical performance of the finished product of the electrochromic device (after the electrochromic device is matched with other film layers) cannot be reflected by the performance test of the semi-finished product when the electrochromic device is not matched with other film layers, and the detection of the optical performance (especially the response time) of the finished product of the electrochromic device cannot be realized by the transmittance scheme in the conventional technology.
In addition, the whole production efficiency of the device can be seriously influenced by detecting the response time performance of the electrochromic device in the semi-finished product stage, and meanwhile, whether the whole response time performance of the device is changed after the device is finished has uncontrollable performance and uncertainty. The semi-finished electrochromic device membrane is not attached to a protective layer (a glass cover plate or a protective layer membrane) so that the exposure time is long, namely the open-time is long, and the reliability is influenced by large water inflow of the device in the early stage. When the semi-finished electrochromic device diaphragm is detected in the middle section, due to the fact that the diaphragm is not supported by structures such as cover plate glass, ITO cracks, folds and other adverse effects are generated by possible operation bending in the testing process, and therefore the overall yield of the device is reduced.

A cellular phone is an electronic device equipped with a cellular communication module.
Referring to fig. 1, fig. 1 is a schematic flow chart of an embodiment of a method for detecting a color-changing response time of a color-changing device according to the present application, and the detection method in the embodiment of the present application can be used for detecting color-changing response times of transparent, translucent, and opaque color-changing devices. The semitransparent and opaque color-changing device can be specifically a color-changing device structure which adopts a base material with low transmittance, a color-changing material and the like to cause the low transmittance or even complete opacity of the color-changing device; the color-changing device can also be a shell assembly formed by matching a transparent color-changing device and other films with low transmittance or non-transparency (such as the color-changing device, a texture film, ground glass, a color film and the like) or other color-changing devices. The color-changing device in the embodiment of the present application may be an electrochromic device, a photochromic device, a magneto-chromic device, and the like.
One application of the color-changing device or the assembly thereof is on a casing of an electronic device, and the color-changing device or the assembly thereof is used for realizing a color-changing effect of the casing of the electronic device. The electronic device may include a mobile phone, a tablet computer, a notebook computer, a wearable device, etc., which are not listed here. The method for detecting the color change response time of the color change device in the present embodiment includes, but is not limited to, the following steps. It should be noted that, in the flow method in this embodiment, the order of each step does not represent that there is a certain sequential execution relationship, and some steps without a causal relationship may be performed synchronously or sequentially.
The detection method comprises the following steps: step S100, a constant voltage square wave signal with a fixed period is applied to the electrochromic device.
In this step, referring to fig. 2, fig. 2 is a schematic diagram of applying a constant voltage square wave signal to the electrochromic device, wherein a fixed period T of the constant voltage square wave signal is greater than a full color-changing period of the electrochromic device. That is, the period T of the constant voltage square wave signal is such that the electrochromic device can realize a complete color change process. Optionally, the constant voltage value of the constant voltage square wave signal is greater than or equal to the standard voltage value of the electrochromic device capable of realizing complete color change. Generally, in the process of color changing of the electrochromic device, a minimum voltage value, namely a standard voltage value, which can realize complete color changing exists, and the electrochromic device can realize complete color changing only when the voltage value is reached. The constant voltage value of the constant voltage square wave signal needs to be greater than or equal to the standard voltage value of the electrochromic device capable of realizing complete color change. For example, the standard voltage value for achieving complete color change of the electrochromic device in the present embodiment is 1.2V, and the constant voltage value of the constant voltage square wave signal may be 1.2V, 1.3V, or 1.5V in the illustrated embodiment.
The detection method further comprises the following steps: step S200, emitting light with specific wavelength to the electrochromic device.
In step S200, the specific wavelength of the light is adapted to the color-changing color of the electrochromic device. Specifically, the sensitivity of light with different wavelengths to different electrochromic devices (colored states) is different, i.e. the reflectivity of the electrochromic device to be detected at a specific wavelength needs to be characterized. For example, an electrochromic device in the magenta colored state preferably corresponds to light having a wavelength of about 550nm, and an electrochromic device in the blue colored state preferably corresponds to light having a wavelength of about 600 nm.
The detection method further comprises the following steps: step S300, obtaining the waveform of the light after the light is reflected by the electrochromic device.
In this step, data acquisition may be performed by a reflectance instrument. Wherein the light scattering and light absorption of the selected test area should not be too strong. Optionally, the time interval of sampling is no greater than 0.1 s. Specifically, the number may be 0.1s, 0.05s, 0.02s, or the like, and is not particularly limited herein. The continuity of data acquisition can be made better. Referring to fig. 3, fig. 3 is a waveform diagram of the reflected light obtained in the embodiment of the present application. In the waveform of the embodiment shown in fig. 3, the reflectance of the reflected light substantially fluctuates between 4% and 8%.
The detection method further comprises the following steps: in step S400, the color change response time of the electrochromic device is determined based on the time interval between adjacent peaks and valleys of the waveform.
In this step, please continue to refer to fig. 3, in which the time interval between the dotted line a and the dotted line b in fig. 3 is the fading response time in one color cycle. And the time interval between the dotted line c and the dotted line d in fig. 3 is the coloring response time in one color-changing period.
The method for detecting the color-changing response time of the electrochromic device is based on a reflection principle, obtains a reflected light waveform of light passing through the electrochromic device, and determines the color-changing response time of the electrochromic device based on a time interval between adjacent wave crests and wave troughs of the reflected light waveform. The detection method can solve the testing difficulty of the light-tight and non-uniform light-transmission electrochromic device without testing at the semi-finished product stage, thereby improving the production efficiency and the product quality, and has the characteristics of simple detection flow and high detection accuracy and reliability.
In addition, the step of calculating the time interval between adjacent peaks and troughs of the waveform as the color-changing response time of the electrochromic device may specifically include the following steps. Referring to fig. 4, fig. 4 is a schematic block diagram of a process of calculating a time interval between adjacent peaks and troughs of the reflected light waveform as a color change response time of the electrochromic device according to an embodiment.
Step S410, obtaining a color-changing response interval corresponding to a preset percentage of the difference value between adjacent wave crests and wave troughs of the waveform. Referring to fig. 3, a dashed line X in fig. 3 is shown as a color-changing response interval (specifically, a color-fading response interval in the present embodiment), and a dashed line Y is shown as another color-changing response interval (specifically, a coloring response interval in the present embodiment). The difference between the top and the bottom of the dotted line frames X and Y may be a preset percentage of the difference between the adjacent peaks and troughs of the waveform, the preset percentage may be 80-90% of the difference between the adjacent peaks and troughs of the waveform, and the preset percentage may specifically be 80%, 82%, 85%, 90%, and other numerical values of the difference between the adjacent peaks and troughs of the waveform, which is not specifically limited herein. By setting the preset percentage of the difference value between the adjacent wave crest and the adjacent wave trough, compared with the method that the difference value between the adjacent wave crest and the adjacent wave trough is directly defined as a color-changing response interval, the waveform noise can be reduced, and the accuracy is improved.
And step S420, taking the time interval corresponding to the color-changing response interval as the color-changing response time of the electrochromic device.
Referring to fig. 3, the time interval corresponding to the width between the left and right sides of the dashed line frames X and Y in fig. 3 is the color change response time of the electrochromic device. Wherein, the time interval corresponding to the width of the dotted line frame X is the fading response time of the electrochromic device; the time interval corresponding to the width of the dashed box Y is the coloration response time of the electrochromic device.
In addition, in some other embodiments, color-changing response intervals in multiple periods of the waveform may also be obtained, please refer to fig. 5, fig. 5 is another waveform diagram of the reflected light obtained in the embodiment of the present application, and in this embodiment, 6 color-changing response intervals in three periods of a dashed frame X, Y, Z, W, P, Q may be obtained, where the dashed frame X, P, W may be represented as a color-changing response interval, and the dashed frame Y, Q, Z may be represented as a color-changing response interval.
Optionally, the step of taking the time interval corresponding to the color-changing response interval as the color-changing response time of the electrochromic device may include: and taking the average value or the median value of the time intervals corresponding to the color change response intervals in the multiple periods as the color change response time of the electrochromic device. Specifically, the following description will take, as an example, 6 color-change response intervals in three periods of the dashed box X, Y, Z, W, P, Q in fig. 5. For example, the time intervals corresponding to the fade response interval boxes X, P, W are 1.3s, 1.4s and 1.5s, respectively, the time intervals corresponding to the inter-dashed boxes X, P, W are averaged, that is, (1.3+1.4+1.5)/3 is 1.4s, and the value of 1.4s is used as the fade response time of the electrochromic device. In addition, the median of the time intervals corresponding to the dotted line boxes X, P, W may be taken as the fading response time of the electrochromic device, and the median of 1.3s, 1.4s, and 1.5s may be 1.4 s. Similarly, the time intervals corresponding to the colored response interval dashed boxes Y, Q, Z may be 1.2s, 1.4s, and 1.3s, respectively, and then the time intervals corresponding to the inter-dashed boxes Y, Q, Z may be averaged, that is, (1.2+1.4+1.3)/3 is 1.3s, and the value of 1.3s is taken as the fading response time of the electrochromic device. In addition, the median of the time intervals corresponding to the dotted line boxes Y, Q, Z may be taken as the fading response time of the electrochromic device, and the median of 1.2s, 1.4s, and 1.3s may be 1.3 s.
The method for detecting the color change response time of the electrochromic device based on the reflectivity principle in the embodiment of the application can be mutually verified with detection schemes based on other principles, such as a Lab principle and a RGB color system principle. The embodiments of the present application will not be described in detail with respect to the other principles of the method for detecting the color change response time of the electrochromic device.
