Among them, the photosensitive display function of air conditioners has become widespread. Air conditioners use photosensitive sensors to read the brightness parameters of the environment and control the brightness of the display based on the ambient brightness. However, traditional photosensitive display functions have many drawbacks. The data collected is too singular and easily affected by various factors such as time and environment.

[0029] This embodiment provides a brightness adjustment method for a display panel running on a mobile terminal, computer terminal, or similar computing device. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0030] Figure 2 This is a flowchart of a brightness adjustment method for a display panel according to an embodiment of this application. The display panel is mounted on an air conditioner, such as... Figure 2 As shown, the method includes the following steps:

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

[0032] Specifically, the air conditioner's internal software or firmware stores a fixed preset display brightness value. When brightness adjustment is needed, the program first reads this fixed value as the starting point for adjustment. The preset display brightness may be stored in the air conditioner's non-volatile memory (such as EEPROM or flash memory) so that the user's last set brightness value can be retained after a power outage. When the air conditioner starts, the program reads this value from the memory.

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

[0034] Specifically, while using a photosensor to collect ambient light intensity, the output display brightness is corrected by comprehensively considering factors including the ambient light coefficient, panel aging level, and user adaptation coefficient. The ambient light coefficient is calculated as the ratio of the current average light intensity to the standard light intensity value; the panel aging level is calculated and converted from the air conditioner's usage time; and the user adaptation coefficient is obtained from user feedback via the app. The display brightness control logic is then used to control the display brightness based on the light intensity collected by the sensor and the aforementioned three correction values.

[0035] The brightness correction data includes the ambient daylight factor. Obtaining the brightness correction data includes the following steps:

[0036] Step S301: Obtain multiple actual ambient light intensities within a preset time period. The actual ambient light intensity is the actual ambient light intensity of the air conditioner as collected by the photosensitive sensor.

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

[0038] Step S303: Calculate the ratio of the current average light intensity to the standard light intensity value to obtain the initial daylight factor;

[0039] Step S304: Determine the ambient daylight factor based on the relationship between the initial daylight factor and the lower limit and upper limit of the light intensity threshold, respectively.

[0040] Specifically, this allows for the accurate determination of the ambient light coefficient, which is then used to correct the brightness of the air conditioner's display panel. This can solve the problems of inaccurate photosensitive data collection caused by poor ambient lighting angles and dirty panels.

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

[0042] In some instances, after the air conditioner is turned on, it collects the ambient light intensity β through a photosensitive sensor (the collection frequency is determined by the main loop running time of the program; each main loop performs AD sampling once and records the sampling results to a temporary array). It calculates and records the average light intensity Da_β for that hour once per hour and records it to the memory chip. After the air conditioner turns on the automatic brightness adjustment function, it reads all the average light intensities Da_β from the memory chip and determines the average value of all the average light intensities Da_β as the current average light intensity.

[0043] In some cases, it is not necessary to record the average light intensity per hour; instead, the average value of all average ambient light intensities collected over a preset time period can be directly calculated.

[0044] The determination of the ambient daylight factor, based on the relationship between the initial daylight factor and the lower and upper limits of the light intensity threshold, includes the following steps:

[0045] Step S3031: If the initial daylight factor is less than the lower limit of the light intensity threshold, the initial daylight factor is determined as the ambient daylight factor.

[0046] Step S3032: If 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: If 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, this approach comprehensively considers the impact of weather, time, and other factors on indoor light intensity. The initial daylight factor e = Da_β / Z, where Z is the standard light intensity value measured in the laboratory. The ratio of the current average ambient light intensity to the standard light intensity value is used as a weighted value to correct the display brightness. If the initial daylight factor 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 indicates poor ambient lighting, requiring adjustment of the display brightness based on the ambient lighting conditions. In this case, the initial daylight factor e is determined as the ambient daylight factor E, which is corrected according to the current environment. If the initial daylight factor e is between the comfortable light intensity [f1, f2] (i.e., between the lower and upper limits of the light intensity threshold), it indicates suitable ambient lighting, and the ambient daylight factor E = 1, requiring no correction. If the initial daylight factor 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 indicates that the environment is too bright, and the ambient daylight factor E = f2, at which point the ambient daylight factor reaches its upper limit.

[0049] In addition, light intensity is usually measured in lux. For bedrooms, the suitable light intensity range is generally between 100 lux and 300 lux. In actual programs, the values ​​of f1 and f2 are also around 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] The brightness correction data includes the panel transmittance coefficient. Obtaining the brightness correction data includes the following steps:

[0051] Step S401: Obtain the initial light transmittance of the display panel and the usage time of the air conditioner. The initial light transmittance is at least related to the material of the display panel.

[0052] Obtaining the initial transmittance of the display panel includes the following steps:

[0053] Step S4011: Obtain 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: Obtain the target mapping relationship, which is the mapping relationship between the panel material, the panel processing technology, the panel color and the panel transmittance.

[0055] Step S4013: Determine the initial light transmittance of the display panel of the air conditioner based on the material of the display panel, the processing technology of the display panel, the panel color of the display panel, and the target mapping relationship.

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

[0057] Step S402: Obtain the formula for determining the light transmittance. Where S is the brightness correction data, S0 is the initial transmittance of the display panel, t is the usage time of the air conditioner, and k is the attenuation constant;

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

[0059] Specifically, this solves the problem of inaccurate photosensitivity caused by panel and mask aging after prolonged use. Since air conditioner panels are mostly injection-molded, their light transmittance gradually decreases over time due to aging, UV exposure, and other factors. The attenuation constant represents the rate of decrease in light transmittance over time; e is the base of the natural logarithm, approximately 2.71828, and t is the cumulative usage time of the air conditioner. The formula for determining the light transmittance coefficient shows that the panel's light transmittance decays exponentially with time. Therefore, S can also be referred to as the panel's aging degree and used as a weighted value for correcting display brightness.

[0060] The brightness correction data includes the photosensitive adaptation coefficient. Obtaining the brightness correction data includes the following steps:

[0061] Step S501: Obtain the initial photosensitivity coefficient set by the user;

[0062] Step S502: If the initial photosensitivity coefficient is less than the first photosensitivity coefficient, the first photosensitivity coefficient is determined as the photosensitivity adaptation coefficient.

[0063] Step S503: If 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.

[0064] Step S504: If the initial photosensitivity coefficient is greater than the second photosensitivity coefficient, the initial photosensitivity coefficient is determined 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 slid by the user 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 only allows the user to set the lowest brightness to 60% at most, to prevent the user from setting it too low and resulting in a poor display effect during the day. When the user sets the initial photosensitive coefficient a lower than A1, a prompt "Do you want to turn off the light?" will pop up on the mobile phone APP side 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 around 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: The preset display brightness of the display panel is corrected 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 is finally established for the target display brightness X, ambient light coefficient, panel aging degree, and user experience value. The correction formula is X=X0×E×A×S. This formula indicates that the brighter the ambient light, the darker the user's perception, and the higher the panel aging degree (the lower the light transmittance), the brighter the display output brightness should be.

[0073] The brightness adjustment method for the display panel described in this 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, it obtains brightness correction data, which includes at least one of the following: ambient light coefficient, panel transmittance coefficient, and photosensitive adaptation coefficient. The ambient light coefficient represents the ambient light intensity at the current moment, the panel transmittance coefficient represents the light transmittance of the display panel, and the photosensitive 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. This method corrects the output display brightness based on the external light intensity, considering the ambient light coefficient, panel aging degree, and user adaptation coefficient. It solves the problem that traditional air conditioner brightness display control is easily affected by environmental factors, resulting in inaccurate brightness adjustment, and addresses the problem that the photosensitive display function of existing air conditioners collects too little data and has inaccurate brightness.

[0074] To enable those skilled in the art to better understand the technical solution of this application, the implementation process of the brightness adjustment method of the display panel of this application will be described in detail below with reference to specific embodiments.

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

[0076] Step S1: First, enable the automatic 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 cumulative air conditioning usage time t from the memory chip. Then, use the WiFi module to obtain the photosensitive adaptation coefficient A, light intensity standard value Z and panel factory transmittance S0 set on the user's APP.

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

[0078] Step S3: If the initial daylight factor is less than the lower limit of the light intensity threshold, the initial daylight factor is determined as the ambient daylight factor; if 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; if 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.

[0079] Step S4: If the initial photosensitivity coefficient is less than the first photosensitivity coefficient, the first photosensitivity coefficient is determined as the photosensitivity adaptation coefficient; if 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; if 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 modified formula X=X0×E×A×S, where X is the target display brightness, X0 is the preset display brightness, E is the ambient light coefficient, A is the photosensitive adaptation coefficient, and S is the panel transmittance coefficient.
