The electronic device can comprise a display screen and an electrochromic layer arranged on the display screen, wherein the electrochromic layer mainly refers to a film layer with an electrochromic function, and the electrochromic layer refers to a phenomenon that optical properties (such as reflectivity, light transmittance, absorptivity and the like) of a material generate stable and reversible color change under the action of an external electric field. Electrochromism is represented by reversible changes of color and transparency of materials in appearance, materials with electrochromism performance can be called as electrochromism materials, and film layers made of the electrochromism materials can be called as electrochromism layers.
Referring to fig. 1, the electrochromic layer may include two conductive layers stacked, 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 Antimony Tin Oxide (ATO).
The color-changing layer is a core layer of the electrochromic layer and is also a layer where a color-changing reaction occurs. The material of the color-changing layer may be classified into an inorganic electrochromic material and an organic electrochromic material according to types. The inorganic electrochromic material may be tungsten trioxide (WO)3) Or nickel oxide (NiO). The organic electrochromic material mainly comprises polythiophene and derivatives thereof, viologen, tetrathiafulvalene, metal phthalocyanine compounds and the like.
The electrolyte layer is composed of a special conductive material such as a liquid electrolyte material containing a solution of lithium perchlorate, sodium perchlorate, or the like, or may be a solid electrolyte material.
The ion storage layer plays a role in storing charges in the electrochromic layer, 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 layer is ensured.
As shown in fig. 2, when a certain voltage is applied between the two transparent conductive layers, the material of the color-changing layer of the electrochromic layer undergoes an oxidation-reduction reaction under the voltage, and thus a color change occurs.
For example, when a voltage applied between two transparent conductive layers of the electrochromic layer is changed from 0V to 1V, the electrochromic layer may be changed from white to red. When a voltage applied between the two transparent conductive layers is changed from 0V to 1.2V, the electrochromic layer 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 layer may be changed from black to white, and so on.
As shown in fig. 3, fig. 3 is a schematic flowchart of a display adjustment method provided in an embodiment of the present application, and is applied to an electronic device, where the electronic device includes a display screen and an electrochromic layer disposed on the display screen, and a specific flowchart may be as follows:
101. an aging area of the display screen and an aging level of the aging area are determined.
In this embodiment, the aging area mainly refers to an area where display is affected when the light emitting elements (i.e., display pixels) of the display screen are aged, and the aging level reflects the degree of the affected display, and generally, the higher the aging level is, the poorer the display effect of the aging area is. The aging area detection method includes various methods, for example, the display screen can be controlled to display a pure color picture, such as pure white or pure blue, and the aging area is found out through the difference of the display effect between adjacent display pixels, or the aging area is found out through the difference between the actual display effect and the ideal display effect of each display pixel.
For example, the step 101 may specifically include:
1-1, controlling the display screen to display according to a first preset input condition, wherein the first preset input condition is set according to a preset display parameter, and the preset display parameter comprises display brightness and/or display color.
In this embodiment, the first preset input condition and the preset display parameter may be both set manually, the preset display parameter mainly refers to an ideal parameter when the display screen is a pure color, and the first preset input condition may be input of current or voltage on each display pixel, for example, when the display screen displays a full white or full black screen, current or voltage that should be theoretically applied to each display pixel.
1-2, acquiring the current display parameters of the display pixels in the display screen.
In this embodiment, the actual display parameters (i.e., the current display parameters) of the display pixels may be detected by a sensor, for example, the actual display brightness is detected by a light sensor, and the actual display color is detected by a color sensor.
1-3, determining an aging area of the display screen and an aging grade of the aging area according to the current display parameter and a preset display parameter.
For example, the steps 1 to 3 may specifically include:
determining the display error of the corresponding display pixel according to the current display parameter and the preset display parameter;
judging whether a display pixel with the display error exceeding a preset threshold exists or not;
if so, taking the display pixel with the display error exceeding a preset threshold value as a target pixel;
and taking the area where the target pixel is as an aging area, and determining the aging grade of the corresponding aging area according to the display error of the target pixel.
In this embodiment, the preset threshold may be set manually, and a reasonable variation range may exist between the actual display parameter and the ideal real parameter in consideration of a certain error in the detection of the display parameter by the sensor. The display screen may have a plurality of aging areas, and the aging grade corresponding to each aging area may be different, for the display pixels which have aged, a certain difference may exist between the actual display parameter and the theoretical display parameter, and the larger the aging degree is, the larger the difference is.
Further, the step of "determining the display error of the corresponding display pixel according to the current display parameter and the preset display parameter" may specifically include:
when the preset display parameter comprises display brightness or display color, calculating a difference value between the current display parameter and the preset display parameter as a display error of the corresponding display pixel;
when the preset display parameters comprise display brightness and display color, calculating a difference value between the current display parameters and the preset display parameters of the same parameter type; and performing weighted calculation on the difference value according to the preset weight corresponding to each parameter type to obtain the display error of the corresponding display pixel.
In this embodiment, when determining the display error through a plurality of parameters, a weight may be set for each parameter in advance as a preset weight, and the preset weight may be obtained according to a large amount of experimental data, and generally, the larger the preset weight value is, the larger the aging influence of components on the corresponding type parameter is represented.
Further, the step of "determining the aging level of the corresponding aging area according to the display error of the target pixel" may specifically include:
determining a preset grade corresponding to the display error of the target pixel as an aging grade of a corresponding aging area; or,
controlling the display screen to display according to a second preset input condition, and detecting the temperature rising rate of the target pixel within a preset time length;
and determining the aging grade of the corresponding aging area according to the temperature rising rate and the display error of the target pixel.
In this embodiment, the aging level may be determined directly according to the display error, or may be determined by combining the temperature change condition, for example, the aging level may be determined by performing weighted calculation on the temperature rise rate and the display error and using the weighted result. The preset level and the second preset input condition may be set manually, the preset level may be multiple, each preset level is usually associated with an error range, at this time, it is required to determine which error range the display error of the target pixel belongs to, and the preset level corresponding to the error range is the aging level. The second preset input condition is mainly used for rapidly raising the temperature of the display screen in a short time, and may be adjustment of the brightness of the display screen, the number of running applications, the color of a display screen, and the like, for example, the brightness of the display screen is maximized, a plurality of running applications with high power consumption are all started, or the display screen displays bright colors, and the like, so that the temperature of the display screen can be rapidly raised. Generally, the higher the aging region, the faster the temperature rise and the greater the magnitude of the temperature rise.
102. And acquiring the driving voltage corresponding to the aging grade as a target voltage.
In this embodiment, when the preset levels are set, a driving voltage may be associated with each preset level, where the driving voltage is mainly used for being applied to the electrochromic layer to display a color of the electrochromic layer, and the magnitude of the driving voltage determines the depth of the color displayed by the electrochromic layer.
103. Applying the target voltage to the electrochromic layer on the aged region to perform display adjustment on the aged region, wherein the electrochromic layer on the aged region displays a color corresponding to the target voltage.
In this embodiment, the electrochromic layer is a film layer made of an electrochromic material, and the film layer is covered on the display screen in a coating manner. When the aging area exists in the display screen, the color compensation can be carried out by utilizing the electrochromic layer in the area, so that the color displayed by the electrochromic layer in the area is superposed with the color displayed by the display pixels, and the influence of the aging of components on the display effect of the screen is eliminated.
It can be known from the foregoing that, the display adjusting method provided in this embodiment is applied to an electronic device, where the electronic device includes a display screen and an electrochromic layer disposed on the display screen, and the aging region of the display screen and the aging level of the aging region are determined, and a driving voltage corresponding to the aging level is obtained as a target voltage, and then the target voltage is applied to the electrochromic layer on the aging region to perform display adjustment on the aging region, where the electrochromic layer on the aging region displays a color corresponding to the target voltage, so that color compensation can be performed on the aging screen by using characteristics of an electrochromic material, and a good display effect is still maintained when the display screen is aged.
In the present embodiment, a description will be made from the perspective of a display adjustment device, and in particular, the display adjustment device will be integrated into an electronic apparatus, which includes a display screen and an electrochromic layer provided on the display screen.
Referring to fig. 4, a specific flow of a display adjustment method may be as follows:
201. the electronic equipment controls the display screen to display according to a first preset input condition, wherein the first preset input condition is set according to a preset display parameter, and the preset display parameter comprises display brightness and/or display color.
For example, the first predetermined input condition may be a current or a voltage that should theoretically be applied to each display pixel when the display screen displays a full white or full black picture. The user may click a designated key to trigger the aging area detection, or the electronic device may automatically trigger the aging area detection periodically.
202. The electronic equipment acquires the current display parameters of the display pixels in the display screen and determines the display errors of the corresponding display pixels according to the current display parameters and the preset display parameters.
For example, when the display screen displays a full white or full black picture, the actual display brightness may be obtained by the light sensor, the actual display color may be obtained by the color sensor, and the display error between the actual display brightness and/or the display color and the ideal display brightness and/or the display color may be calculated.
For example, the step of "determining the display error of the corresponding display pixel according to the current display parameter and the preset display parameter" may specifically include:
when the preset display parameter comprises display brightness or display color, calculating a difference value between the current display parameter and the preset display parameter as a display error of the corresponding display pixel;
when the preset display parameters comprise display brightness and display color, calculating a difference value between the current display parameters and the preset display parameters of the same parameter type;
and performing weighted calculation on the difference value according to the preset weight corresponding to each parameter type to obtain the display error of the corresponding display pixel.
For example, for different numbers of parameters, the display error may be calculated in different manners, for example, for a single parameter, the difference between the ideal parameter and the actual parameter may be directly used as the display error, for a plurality of parameters, each difference may be calculated first, and then the total difference may be calculated as the display error by using a weighting algorithm, such as a T1+ bT2, where T1 is the difference between the ideal display brightness and the actual display brightness, a is a preset weight value of the display brightness, T2 is the difference between the ideal display color and the actual display color, and b is a preset weight value of the display color.
203. The electronic device determines whether there is a display pixel with the display error exceeding a preset threshold, if so, the following step 204 is executed, and if not, no operation may be executed.
204. The electronic equipment takes the display pixel with the display error exceeding a preset threshold value as a target pixel and takes the area where the target pixel is located as an aging area.
For example, the predetermined threshold may be determined according to the detection accuracy of different sensors, and the higher the accuracy, the smaller the predetermined threshold may be set.
205. And the electronic equipment controls the display screen to display according to a second preset input condition, detects the temperature rising rate of the target pixel within a preset time length, and then determines the aging grade of the corresponding aging area according to the temperature rising rate of the target pixel and the display error.
For example, the second preset input condition may be that the brightness of the display screen reaches a maximum value, a plurality of running applications with higher power consumption are all started, and/or a display screen displays a brighter color, the preset time duration may be 2 minutes set manually, and the electronic device may detect the temperature of the aging area in real time through the temperature sensor to determine the temperature increase rate. Generally, the greater the error value, the greater the rate of temperature rise, and the higher the corresponding level of aging.
206.
