[0029] In this embodiment, a method for adjusting the brightness of a display panel running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0030] Figure 2 FIG. 1 is a flow chart of a method for adjusting the brightness of a display panel according to an embodiment of the present application. The display panel is installed on an air conditioner, such as Figure 2 As shown, the method comprises the following steps:

[0031] Step S201, obtaining a preset display brightness of the display panel, wherein the preset display brightness is a default display brightness of the display panel at the current moment;

[0032] Specifically, a fixed preset display brightness value is stored in the software or firmware inside the air conditioner. When brightness adjustment is required, the program will first read this fixed value as the starting point for adjustment. The preset display brightness may be stored in the non-volatile memory (such as EEPROM or flash memory) of the air conditioner so that the brightness value last set by the user can be retained after power failure. When the air conditioner is started, the program will read this value from the memory.

[0033] Step S202, obtaining brightness correction data, wherein the brightness correction data includes at least one of the following: an ambient light coefficient, a panel light transmittance coefficient, and a photosensitivity adaptation coefficient, wherein the ambient light coefficient represents the ambient light intensity at the current moment, the panel light transmittance coefficient represents the light transmittance of the display panel, and the photosensitivity adaptation coefficient represents the display brightness required by the user;

[0034] Specifically, while using the photosensitive sensor to collect the external light intensity, the output display brightness is corrected by comprehensively considering the ambient light factor, panel aging degree and user adaptation coefficient. The ambient light factor is calculated by the ratio of the current average light intensity to the standard light intensity value, the panel aging degree is calculated and converted by the use time of the air conditioner, and the user adaptation coefficient is obtained by the user's modification feedback on the APP. The display brightness function control logic is controlled according to the light intensity collected by the sensor and the above three correction values.

[0035] Wherein, the brightness correction data includes the ambient lighting coefficient, and obtaining the brightness correction data includes the following steps:

[0036] Step S301, obtaining a plurality of actual ambient light intensities within a preset period of time, wherein the actual ambient light intensity is the actual ambient light intensity of the air conditioner collected by a photosensitive sensor;

[0037] Step S302, calculating the average value of all the actual ambient light intensities to obtain the current average light intensity;

[0038] Step S303, calculating the ratio of the current average light intensity to the standard light intensity value to obtain an initial daylighting factor;

[0039] Step S304, determining the ambient daylight coefficient according to the magnitude relationships between the initial daylight coefficient and the lower limit of the light intensity threshold and the upper limit of the light intensity threshold.

[0040] Specifically, this can accurately determine the ambient light coefficient, and then use the ambient light coefficient to correct the brightness of the air conditioner display panel, which can solve the problem of inaccurate photosensitivity collection caused by poor ambient lighting angles and dirty panels.

[0041] The preset time period is the time period from when the air conditioner is turned on to the current moment, that is, the current average light intensity is the average value of all light intensities collected from when the air conditioner is turned on to the current moment.

[0042] In some instances, after the air conditioner is turned on, the ambient light intensity β is collected through a photosensor (the collection frequency is determined by the running time of the main loop of the program, each main loop executes an AD sampling and records the sampling result in a temporary array), and the average light intensity Da_β within the hour is calculated and recorded once every hour and recorded in the memory chip. After the air conditioner turns on the automatic brightness adjustment function, the air conditioner reads all the average light intensities Da_β from the memory chip and determines the average of all the average light intensities Da_β as the current average light intensity.

[0043] In some examples, the average light intensity per hour may not be recorded, and the average value of all average ambient light intensities collected during a preset period of time may be directly calculated.

[0044] According to the magnitude relationship between the initial daylight coefficient and the lower limit of the light intensity threshold and the upper limit of the light intensity threshold, the ambient daylight coefficient is determined, including the following steps:

[0045] Step S3031, when the initial daylight coefficient is less than the lower limit of the light intensity threshold, determining the initial daylight coefficient as the ambient daylight coefficient;

[0046] Step S3032, when the initial daylight factor is greater than or equal to the lower limit of the light intensity threshold and less than or equal to the upper limit of the light intensity threshold, a preset correction value is determined as the ambient daylight factor; the preset correction value is 1;

[0047] Step S3033: When the initial daylight factor is less than the upper limit of the light intensity threshold, the upper limit of the light intensity threshold is determined as the ambient daylight factor.

[0048] Specifically, the influence of weather, time, etc. on indoor light intensity can be comprehensively considered in this way. Among them, the initial daylight coefficient e=Da_β / Z, where Z is the standard light intensity value measured in the laboratory. The ratio of the current average light intensity to the standard light intensity value is used as the weighted value for correcting the display brightness. If the initial daylight coefficient e is lower than the lower limit of the comfortable light intensity threshold f1 (i.e., the lower limit of the light intensity threshold), it means that the ambient lighting is poor and the display brightness needs to be adjusted according to the ambient lighting conditions. At this time, the initial daylight coefficient e is determined as the ambient daylight coefficient E, and the ambient daylight coefficient is corrected according to the current environment; if the initial daylight coefficient e is between the comfortable light intensity [f1, f2] (i.e., between the lower limit of the light intensity threshold and the upper limit of the light intensity threshold), it means that the ambient lighting is suitable, then the ambient daylight coefficient E=1 and no correction is required. If the initial daylight coefficient e is higher than the upper limit of the comfortable light intensity threshold f2 (i.e., the upper limit of the light intensity threshold), it means that the environment is bright, then the ambient daylight coefficient E=f2, and the ambient daylight coefficient reaches the upper limit value at this time.

[0049] In addition, light intensity is usually measured in lux. For a bedroom, the appropriate light intensity range is generally between 100 lux and 300 lux. In the actual program, the values ​​of f1 and f2 are also near this range, that is, the lower limit of the light intensity threshold is around 100 lux, and the upper limit of the light intensity threshold is around 300 lux.

[0050] Wherein, the brightness correction data includes the panel transmittance coefficient, and obtaining the brightness correction data includes the following steps:

[0051] Step S401, obtaining the initial light transmittance of the display panel and the usage time of the air conditioner, wherein the initial light transmittance is at least related to the material of the display panel;

[0052] Wherein, obtaining the initial light transmittance of the display panel comprises the following steps:

[0053] Step S4011, obtaining the material of the display panel of the air conditioner, the processing technology of the display panel of the air conditioner, and the panel color of the display panel of the air conditioner;

[0054] Step S4012, obtaining a target mapping relationship, wherein the target mapping relationship is a mapping relationship between the material of the panel, the processing technology of the panel, the panel color of the panel, and the light transmittance of the panel;

[0055] Step S4013, determining the initial light transmittance of the display panel of the air conditioner according to the material of the display panel of the air conditioner, the processing technology of the display panel of the air conditioner, the panel color of the display panel of the air conditioner and the target mapping relationship.

[0056] Specifically, by comprehensively considering the influence of factors such as the display panel material, processing technology and panel color on the panel transmittance, a more accurate panel transmittance can be calculated. Different panel materials have different transmittances, different panel processing technologies (spraying, frosting, engraving, multi-layer spraying, etc.) have different transmittances, and different panel colors have different transmittances.

[0057] Step S402: Obtaining a formula for determining the transmittance coefficient , where S is the brightness correction data, S0 is the initial light transmittance of the display panel, t is the use time of the air conditioner, and k is the attenuation constant;

[0058] Step S403, determining the light transmittance coefficient of the panel according to the light transmittance determination formula.

[0059] Specifically, this can solve the problem of inaccurate photosensitivity collection caused by aging of panels and masks after long-term use. Since most air-conditioning panels are injection molded parts, the light transmittance of plastic panels will gradually decrease over time due to factors such as aging and ultraviolet radiation. The attenuation constant represents the rate of decrease of transmittance over time, e is the base of the natural logarithm, which is approximately equal to 2.71828, and t is the cumulative usage time of the air conditioner. The formula for determining the transmittance coefficient shows that the transmittance of the panel decays exponentially over time. Therefore, S can also be referred to as the degree of aging of the panel here, and it can be used as a weighted value to correct the display brightness.

[0060] Wherein, the brightness correction data includes the photosensitivity adaptation coefficient, and obtaining the brightness correction data includes the following steps:

[0061] Step S501, obtaining the initial photosensitivity coefficient set by the user;

[0062] Step S502, when the initial photosensitivity coefficient is less than the first photosensitivity coefficient, determining the first photosensitivity coefficient as the photosensitivity adaptation coefficient;

[0063] Step S503, when the initial photosensitivity coefficient is greater than or equal to the first photosensitivity coefficient and less than or equal to the second photosensitivity coefficient, determining a preset photosensitivity coefficient as the photosensitivity adaptation coefficient;

[0064] Step S504: when the initial photosensitivity coefficient is greater than the second photosensitivity coefficient, determine the initial photosensitivity coefficient as the photosensitivity adaptation coefficient.

[0065] Specifically, this can solve the problem of poor experience caused by the mismatch between the program settings and the user's habits. Since everyone has different sensitivities to light intensity, simply using the environmental lighting coefficient and the panel light transmittance coefficient to correct the display brightness of the panel may still not conform to the user's usage habits. Therefore, a photosensitive adaptation coefficient A is added. The user can input the current light intensity experience of being too dark or too bright on the mobile phone APP in the form of a percentage slider. The darker the user feels the display is, the larger the A value is, and the brighter, the smaller the A value is. The air conditioner controller communicates with the user's mobile phone through the WiFi module to obtain the photosensitive adaptation coefficient A feedback by the user and uses it to correct the display brightness.

[0066] In some embodiments, the percentage slider that the user slides on the mobile phone corresponds to a display brightness of 0% to 150%, that is, the initial photosensitive coefficient a feedback by the user's mobile phone takes values in [0, 1.5]. When the user feedbacks that a < A1 (the first photosensitive coefficient), the photosensitive adaptation coefficient A = A1, and A1 takes a value of about 0.6. That is, when the user feels that the display brightness is too bright and hopes to be as dark as possible, but the user is only allowed to set the minimum to 60% brightness at the lowest to prevent the user from setting it too low, resulting in a poor display effect during the day. When the user sets the initial photosensitive coefficient a lower than A1, the mobile phone APP side will pop up a prompt "Do you want to turn off the light?" to facilitate the user to decide whether to turn off the display. When the user feedbacks that the initial photosensitive coefficient a > A2 (the second photosensitive coefficient), A = a, and A2 takes a value of about 1.1. That is, when the user feels that the display is darker and hopes to increase the brightness, the maximum value of A is 1.5, that is, 150% display brightness. When the user feedbacks that the initial photosensitive coefficient a is between A1 and A2, the program determines that the display brightness is still executed according to 100%.

[0067] Step S203, use the brightness correction data to correct the preset display brightness of the display panel to obtain the target display brightness of the display panel.

[0068] Specifically, this can solve the problem that the traditional air conditioner automatic brightness display control is easily affected by environmental factors, resulting in inaccurate brightness adjustment, and improves the user's usage experience.

[0069] Among them, the brightness correction data includes the environmental lighting coefficient, the panel light transmittance coefficient, and the photosensitive adaptation coefficient. Using the brightness correction data to correct the preset display brightness of the display panel to obtain the target display brightness of the display panel includes the following steps:

[0070] Step S2031, obtain the correction formula X = X0 × E × A × S, where X is the target display brightness, X0 is the preset display brightness, E is the environmental lighting coefficient, A is the photosensitive adaptation coefficient, and S is the panel light transmittance coefficient;

[0071] Step S2032: Correct the preset display brightness of the display panel using the correction formula and the brightness correction data to obtain the target display brightness of the display panel.

[0072] Specifically, based on the above correction values, a data model of the target display brightness X, the ambient lighting coefficient, the panel aging degree and the user experience value is finally established, that is, the correction formula X=X0×E×A×S. This formula shows that the brighter the ambient lighting, the darker the user's perception, and the higher the panel aging degree (the lower the transmittance), the brighter the display output brightness should be.

[0073] The brightness adjustment method of the display panel mentioned above in the present application first obtains the preset display brightness of the display panel, which is the default display brightness of the display panel at the current moment; then obtains brightness correction data, which includes at least one of the following: ambient light coefficient, panel light transmittance coefficient and photosensitivity adaptation coefficient, the ambient light coefficient represents the ambient light intensity at the current moment, the panel light transmittance coefficient represents the light transmittance of the display panel, and the photosensitivity adaptation coefficient represents the display brightness required by the user; finally, the preset display brightness of the display panel is corrected using the brightness correction data to obtain the target display brightness of the display panel. The method corrects the output display brightness according to the external light intensity, the comprehensive ambient light coefficient, the panel aging degree and the user adaptation coefficient, so as to solve the problem that the brightness display control of the traditional air conditioner is easily affected by environmental factors, resulting in inaccurate brightness adjustment, and the problem that the photosensitive display function of the air conditioner in the prior art collects too single data and the photosensitive display brightness is inaccurate.

[0074] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the brightness adjustment method of the display panel of the present application will be described in detail below in combination with specific embodiments.

[0075] This embodiment relates to a specific method for adjusting the brightness of a display panel. Figure 3 As shown, the following steps are included:

[0076] Step S1: First, turn on the automatic display brightness control function, then use AD sampling to obtain the current ambient light intensity β, and read the current average light intensity Da_β and the accumulated air conditioner usage time t from the memory chip, and obtain the photosensitivity adaptation coefficient A, light intensity standard value Z, and panel factory transmittance S0 set on the user APP through the WiFi module;

[0077] Step S2: Calculate the initial daylight factor and panel aging degree;

[0078] Step S3: When the initial daylight coefficient is less than the lower limit of the light intensity threshold, the initial daylight coefficient is determined as the ambient daylight coefficient; when the initial daylight coefficient is greater than or equal to the lower limit of the light intensity threshold and less than or equal to the upper limit of the light intensity threshold, the preset correction value is determined as the ambient daylight coefficient; when the initial daylight coefficient is less than the upper limit of the light intensity threshold, the upper limit of the light intensity threshold is determined as the ambient daylight coefficient.

[0079] Step S4: When the initial photosensitivity coefficient is less than the first photosensitivity coefficient, the first photosensitivity coefficient is determined as the photosensitivity adaptation coefficient; when the initial photosensitivity coefficient is greater than or equal to the first photosensitivity coefficient and less than or equal to the second photosensitivity coefficient, the preset photosensitivity coefficient is determined as the photosensitivity adaptation coefficient; when the initial photosensitivity coefficient is greater than the second photosensitivity coefficient, the initial photosensitivity coefficient is determined as the photosensitivity adaptation coefficient.

[0080] Step S5: Calculate the target display brightness of the display panel according to the correction formula X=X0×E×A×S, wherein X is the target display brightness, X0 is the preset display brightness, E is the ambient lighting coefficient, A is the photosensitivity adaptation coefficient, and S is the panel transmittance coefficient.
