[0056] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, like reference numerals refer to like elements, unless the context clearly dictates otherwise. The following description of exemplary embodiments is not representative of all possible embodiments consistent with the present application. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0057] Before the display effect control method of the display screen provided by the present disclosure is described, the concept of color temperature involved in the present disclosure is first described.

[0058] When a light source emits light, a set of spectra is generated, and a certain temperature needs to be reached when a pure black body produces the same spectrum. This temperature is the color temperature of the light source, and the unit of color temperature is Kelvin (K). Therefore, the color temperature can be understood as a fictitious black object that emits light of different colors when heated to different temperatures, and the object appears in different colors. Among them, the commonly used color temperature effects include D65 and D75, which can represent the color temperature effect of the display screen. When the color temperature effect of the display screen is D65, it can be considered that the display screen in the working process is a light source with a color temperature of 6500K; when the color temperature effect of the display screen is D75, it can be considered that the display screen in the working process is a light source with a color temperature of 7500K. When the color temperature exceeds 5000K, the light source is called a cold light source, and the display effect is blue; when the color temperature is lower than 3000K, the light source is called a warm light source, and the display effect is yellow.

[0059] Most terminal devices currently have a display screen color style adjustment function to meet the individual needs of users for display screen color temperature display. However, in the prior art, the brightness of the display screen is mostly adjusted according to the automatic backlight curve, that is, the ambient light value is collected by the light sensor, the backlight value corresponding to the collected ambient light value is found in the backlight curve table, and then the display brightness of the display screen is adjusted according to the backlight value. When adjusting the display brightness of the display screen, only the ambient light parameter is considered, and the influence of the color temperature of the display screen on the brightness of the display screen is not considered. When the display screen displays different color temperature effects, such as warm color temperature, standard color temperature, and cold color temperature, there is a relatively large difference in the display brightness of the display screen, for example, at the same physical backlight value, the brightness of the display screen with a cold color temperature is lower than that of the display screen with a standard color temperature. Referring to Figure 8 and Figure 9 , as shown in Figure 8 shows an interface effect diagram displayed with a warm color temperature effect in the related art, Figure 9 shows an interface effect diagram displayed with a cold color temperature effect in the related art, by Figure 8 and Figure 9It can be known by comparison that when the display screen displays at the same physical backlight value, the display interface displayed by the cold color temperature effect is obviously lower in display brightness than the display interface displayed by the warm color temperature effect, which is easy to give the user the feeling that the display interface is too dark and affects the user's visual experience.

[0060] To solve the above problems, the display effect control method of the display screen is provided in the present disclosure, which is applied to a terminal device with a display screen. When the display brightness of the terminal device does not match the color temperature information, the display brightness of the display screen is adjusted by using the current color temperature information, so that the display brightness of the display screen is adapted to the color temperature display effect of the display screen, avoiding the weakening of the display brightness caused by different color temperature display effects, affecting the user's visual experience, improving the accuracy of the display brightness of the display screen, and improving the user's visual use comfort.

[0061] The exemplary embodiments of the present disclosure provide a display effect control method of a display screen, which is applied to a terminal device with a display screen. The terminal device can be a mobile phone, a tablet computer, a smart robot, a smart wearable device, or other smart electronic devices with a display screen.

[0062] As shown in the display effect control method of the display screen in the present disclosure, the method is realized by a control device of the terminal device, and includes the following steps. Figure 1

[0063] S101, obtaining current color temperature information of the display screen;

[0064] S102, obtaining current display brightness information of the display screen;

[0065] S103, if the current display brightness information does not match the current color temperature information, obtaining target display brightness information matched with the current color temperature information based on the current color temperature information;

[0066] S104, adjusting the display brightness of the display screen based on the target display brightness information.

[0067] In step S101, the control device of the terminal device is always in communication connection with the display screen to control the display content and display effect of the display screen. The control device can obtain the current color temperature information of the display screen through the communication connection with the display screen. The current color temperature information can be automatically set by the control device according to the environmental color temperature information collected by the color temperature sensor, or can be set by the user according to personal preference. The current color temperature information is used to reflect the color temperature under the current display style of the display screen, and the unit of the color temperature information is K.

[0068] ​In step S102, the control device of the terminal device can acquire the current brightness information of the display screen through the communication connection between the display screen. The display brightness can be automatically set by the control device according to the ambient light value collected by the light sensor, or can be set by the user according to personal use habits. The current display brightness information is used to reflect the current brightness of the display screen in the bright screen state, and the unit of the display brightness information is lux.

[0069] In step 103, after acquiring the current color temperature information and the current display brightness information of the display screen, the control device compares the two to determine whether the current color temperature information matches the current display brightness information. If the two do not match, the display brightness of the display screen is adjusted according to the current color temperature information to match the display brightness with the color temperature effect, so that the display brightness does not become dim after the color temperature adjustment.

[0070] In some examples, the current color temperature information and the current display brightness information can be set to multiple gears respectively. For example, 1000K-4000K of the current color temperature information is set to the first gear, 4000K-7000K is set to the second gear, and 7000K-10000K is set to the third gear; 30%-50% of the maximum brightness value of the display screen is set to the first gear, 50%-70% of the maximum brightness value is set to the second gear, and 70%-90% of the maximum brightness value is set to the third gear. If the gear of the current color temperature information is inconsistent with the gear of the current display brightness information, it means that the current color temperature information and the current display brightness information do not match, and the display brightness of the display screen needs to be adjusted to adapt the color temperature display effect of the display screen to the display brightness.

[0071] In other examples, since the color temperature information and the brightness information contain different contents and units, it is difficult to directly compare whether the current color temperature information matches the current display brightness information. In order to facilitate comparison, a corresponding relationship between the color temperature information and the display brightness information can be established in advance. When step S103 is executed, the color temperature information corresponding to the current display brightness information is first determined based on the current display brightness information and the corresponding relationship between the color temperature information and the display brightness information, and then the color temperature information is compared with the current color temperature information. If the two are inconsistent, it means that the current display brightness information and the current color temperature information do not match, and the display brightness of the display screen needs to be adjusted to adapt the color temperature display effect of the display screen to the display brightness, thereby improving the visual experience of the user. For example, the user adjusts the color temperature effect of the display screen from the standard color temperature to the warm color temperature, but does not adjust the brightness of the display screen. At this time, since the color temperature effect has changed, but the display brightness of the display screen has not changed, the color temperature information corresponding to the current display brightness of the display screen is inconsistent with the current color temperature information, so the current color temperature information does not match the current display brightness.

[0072] If the current color temperature information and the current display brightness information do not match, it indicates that the setting of the display brightness of the display screen does not take into account the influence of the current color temperature display effect. For example, in a dim indoor scene, one user sets the display screen to a standard color temperature display effect (6500K), and another user sets the display screen to a bluish color temperature display effect (9300K). Two terminal devices only set the same display brightness according to the ambient light value collected by the light sensor. Then, the display brightness of the terminal device using the bluish color temperature display effect is lower than that of the terminal device using the standard color temperature display effect. In this case, the user watching the screen will cause eye discomfort. Therefore, in order to avoid the above problems, when the current color temperature information and the current display brightness information do not match, the display brightness of the display screen is adjusted based on the current color temperature information. The target display brightness information matched with the current color temperature information is obtained, and the current display brightness is compensated to improve the visual experience of the user.

[0073] In step S104, the display brightness of the display screen is adjusted according to the target display brightness information obtained based on the current color temperature information. It can be ensured that the display screen of the terminal device can be adjusted to a suitable display brightness whether in a standard color temperature display effect or in a cold or warm color temperature display effect. It should be noted that the standard color temperature refers to a color temperature display effect with better display effect, which is set according to the hardware parameters of the display screen of the terminal device when the terminal device is shipped. The numerical values of R (red), G (green), and B (blue) of each pixel point of the display screen during display are all taken as initial values in the standard color temperature state.

[0074] In the present disclosure, when the display brightness of the terminal device does not match the color temperature information, the current color temperature information is used to adjust the display brightness of the display screen, so that the display brightness of the display screen is adapted to the color temperature display effect of the display screen. This avoids weakening of the display brightness caused by different color temperature display effects, affects the visual experience of the user, improves the accuracy of the display brightness of the display screen, and improves the visual use comfort of the user.

[0075] According to an exemplary embodiment, as shown in Figure 2 The display effect control method of the display screen in the present embodiment includes:

[0076] S201, obtaining current color temperature information of a display screen;

[0077] S202, obtaining current display brightness information of the display screen;

[0078] S203, if the current display brightness information matches the current color temperature information, maintaining the current display brightness of the display screen.

[0079] The steps S201 and S202 are the same as the implementation in the above embodiment, and will not be described here again.

[0080] In step S203, if the current display brightness information matches the current color temperature information, it indicates that the color temperature display effect of displaying with the current color temperature information does not affect the display brightness of the display screen, and the display brightness does not need to be compensated, and the current display brightness of the display screen meets the visual needs of the user. Referring to the two examples shown in step S103 in the above embodiment, for example, the current color temperature information is the standard color temperature 6500K, which belongs to the second gear of the current color temperature information, and the current display brightness information is 50%, which belongs to the second gear of the current display brightness information, and the gear of the current color temperature information is consistent with the gear of the current display brightness information, which indicates that the current display brightness information matches the current color temperature information. For another example, if the color temperature information corresponding to the current display brightness information is consistent with the current color temperature information, it indicates that the current display brightness information matches the current color temperature information.

[0081] In the present disclosure, when the current display brightness information matches the current color temperature information, the current display brightness of the display screen can be maintained, and the display brightness of the display screen does not need to be compensated to obtain new brightness information, so as to meet the visual use needs of the user.

[0082] According to one example embodiment, as Figure 3 shown, the display effect control method of the display screen in the present embodiment comprises:

[0083] S301, obtaining a coefficient of the current color temperature of the display screen relative to a preset reference color temperature as current color temperature information;

[0084] S302, obtaining current display brightness information of the display screen;

[0085] S303, determining whether the current display brightness information matches the current color temperature information, if yes, performing step S304; if no, performing steps S305 and S306;

[0086] S304, if the current display brightness information matches the current color temperature information, maintaining the current display brightness of the display screen;

[0087] S305, if the current display brightness information does not match the current color temperature information, obtaining target display brightness information matching the current color temperature information based on the current color temperature information;

[0088] S306, adjusting the display brightness of the display screen based on the target display brightness information.

[0089] The steps S302, S304, S305 and S306 are the same as the implementation in the above embodiment, and will not be described here again.

[0090] In step S301, a ratio coefficient of the current color temperature of the display screen relative to a preset reference color temperature is taken as the current color temperature information, wherein the preset reference color temperature is the color temperature value under the display effect of the standard color temperature. Since the display brightness information and the color temperature information of the display screen are matched under the display effect of the standard color temperature, the display screen does not need to be compensated in brightness, and the current display brightness of the display screen can be maintained for the user, so the color temperature value under the display effect of the standard color temperature is a good reference value, and thus the color temperature value under the display effect of the standard color temperature is taken as the preset reference color temperature, so as to unify the calculation method of the color temperature information under different color temperature effects. The ratio coefficient of the current color temperature of the display screen relative to the preset reference color temperature can be well taken as the current color temperature information of the display screen to represent the current color temperature effect of the display screen. For example, if the coefficient of the current color temperature of the display screen relative to the preset reference color temperature is 1, it indicates that the current color temperature is the standard color temperature; if the coefficient of the current color temperature of the display screen relative to the preset reference color temperature is greater than 1, it indicates that the current color temperature is a blue display effect; and if the coefficient of the current color temperature of the display screen relative to the preset reference color temperature is less than 1, it indicates that the current color temperature is a yellow display effect.

[0091] In step S303, when judging whether the current display brightness information and the current color temperature information are matched, first, a reference color temperature coefficient corresponding to the current display brightness information is obtained based on the current display brightness information. The determination manner of the reference color temperature coefficient is the same as that of the current color temperature information in step S301, and the reference color temperature coefficient can represent the color temperature effect corresponding to the current display brightness information, or the preset reference color temperature can be directly taken as the reference color temperature coefficient. In one example, the display screen originally displays in the standard color temperature display effect and the standard brightness, the user adjusts the color temperature display effect to the cold color temperature display effect, but the display screen still displays in the standard brightness, and the standard brightness is the current display brightness. The color temperature information corresponding to the current display brightness is the reference color temperature coefficient. Since the color temperature parameter corresponding to the current display brightness information before adjustment is the color temperature parameter when displaying in the standard color temperature display effect, the preset reference color temperature is the reference color temperature coefficient. In another example, the display screen originally displays in the cold color temperature effect, and the display screen brightness at this time also matches the cold color temperature. At this time, the reference color temperature coefficient is the color temperature parameter corresponding to the cold color temperature effect. At this time, if the color temperature display effect of the display screen is modified from the cold color temperature display effect to the warm color temperature effect, but the user does not adjust the display screen brightness corresponding to the cold color temperature display effect, the reference color temperature coefficient corresponding to the current display brightness at this time is not equal to the preset reference color temperature.

[0092] Then, the control device judges that the current display brightness information and the current color temperature information are matched if the current color temperature information is the same as the reference color temperature coefficient, and judges that the current display brightness information and the current color temperature information are not matched if the current color temperature information is different from the reference color temperature coefficient.

[0093] The current color temperature information is compared with the reference color temperature coefficient. If the current color temperature information is the same as the reference color temperature coefficient, the current display brightness information matches the current color temperature information. If the current color temperature information is different from the reference color temperature coefficient, the current display brightness information does not match the current color temperature information. For example, if the current color temperature of the display screen in the current color temperature information is 1.25 times the preset reference color temperature, and the reference color temperature coefficient is also 1.25, the current color temperature information is the same as the reference color temperature coefficient, which indicates that the current display brightness information matches the current color temperature information, and the current display brightness 80% of the display screen can be maintained. If the current color temperature of the display screen in the current color temperature information is 1.25 times the preset reference color temperature, and the reference color temperature coefficient is 1, the current color temperature information is different from the reference color temperature coefficient, which indicates that the current display brightness information does not match the current color temperature information, and the current display brightness 50% of the display screen cannot meet the required brightness under the current color temperature information. The target display brightness information that matches the current color temperature information needs to be obtained based on the current color temperature information.

[0094] Due to different personal use requirements and use habits of users, there are many possibilities for adjusting the color temperature display effect of the display screen. The display effect can be adjusted from the preset reference color temperature to the blue display effect, or from the blue display effect to the yellow display effect. Under different color temperature display effects, the display brightness will also change. In order to facilitate the adjustment of the display brightness information of the display screen according to the current color temperature information, so that the display brightness of the display screen can be matched with the current color temperature information, a corresponding relationship between the display screen brightness and the color temperature information can be established in advance. For example, when the display brightness is 50%, the corresponding color temperature coefficient is 1; when the display brightness is 80%, the corresponding reference color temperature coefficient is 1.25. If it is determined that the current color temperature information is 1, but the display screen brightness is only 50% of the highest brightness, it indicates that the display brightness does not match the current color temperature effect, and the display brightness of the display screen is adjusted to 80% of the highest display brightness.

[0095] According to an example embodiment, as shown in Figure 4 the display effect control method of the display screen in the embodiment includes:

[0096] S401, obtaining a color value parameter of a white point in a state of displaying in a current color temperature;

[0097] S402, obtaining a preset color value parameter of a white point in a state of displaying in a preset reference color temperature;

[0098] S403, a ratio of the color value parameter of the white point to the preset color value parameter of the white point is taken as current color temperature information;

[0099] S404, obtaining current display brightness information of the display screen;

[0100] S405, determining whether the current display brightness information matches the current color temperature information, if yes, executing step S406; if no, executing steps S407 and S408;

[0101] S406, if the current display brightness information matches the current color temperature information, maintaining the current display brightness of the display screen;

[0102] S407, if the current display brightness information does not match the current color temperature information, obtaining target display brightness information matching the current color temperature information based on the current color temperature information;

[0103] S408, adjusting the display brightness of the display screen based on the target display brightness information.

[0104] In step S404, S405, S406, S407 and S408, the same as the above embodiment, which will not be repeated here.

[0105] In step S401, the white point refers to a part of the display screen displayed in white in the standard color temperature display state, and the color value parameter of the white point is represented by the RGB three-channel color parameter. The RGB color mode is a color standard in the industry, which is used to obtain various colors by changing the three color channels of red (R), green (G) and blue (B) and superimposing them on each other. RGB represents the three channels of red, green and blue. This standard includes almost all colors that can be perceived by human vision, and is one of the most widely used color systems. The color of all pixel points on the display interface can be represented by the RGB three-channel. Since the current color temperature display effect can be set to a blue-biased display effect or a yellow-biased display effect according to user's preference, the white point will appear blue-biased or yellow-biased in the above two non-standard color temperature display states, that is, the color value parameter of the white point is different from that of the white point in the standard color temperature. For example, in a blue-biased color temperature display effect, the color value parameter of the white point is (176, 224, 230), wherein the color value parameter of the white point is the color value of the white pixel point constituting the image in the standard color temperature. For convenience of description, in the subsequent description, when the color temperature changes from the standard color temperature to the non-standard color temperature, although the color displayed after the color value of the white point in the standard color temperature changes is no longer white, the point is still called the white point in the non-standard color temperature. By obtaining the color value parameter of the white point position in the current color temperature display effect, and based on the color value parameter of the white point position in the standard color temperature, the current color temperature information in the current color temperature display effect of the display screen can be inferred.

[0106] In step S402, the preset color value parameter of the white point in the preset reference color temperature display state is obtained, that is, the color value parameter of the white point in the display effect of the standard color temperature is obtained. Generally, the color value parameter of the white point in the standard color temperature is (255, 255, 255). When the color temperature of the display screen changes, the color value parameter of the white point in different color temperatures also changes accordingly, and the remaining color points also change based on the color value parameter of the white point in the current color temperature. For example, the color value parameter of the white point in the standard color temperature is (255, 255, 255), and as the color temperature changes, when the color temperature becomes a yellowish color temperature, the original white point in the yellowish color temperature is affected by the color temperature and changes from white to a yellowish color. Therefore, the color value parameter of the white point in the yellowish color temperature (even if the color of the white point changes from white to a yellowish color, it is still called a white point) changes and is displayed as (255, 255, 200).

[0107] In some embodiments, the color value parameter of the white point in the display state of the non-standard color temperature can be a product of the coefficient of one or two color channel values in the color value parameter of the white point in the standard color temperature. For example, the R value and the G value in the color value parameter of the white point in the display effect of the bluish color temperature (9000K) are 0.75 times the R value and the G value in the color value parameter of the white point in the standard color temperature. Therefore, the color value parameter of the white point in the display effect of the 9000K color temperature is (191, 191, 255). The R value and the G value in the color value parameter of the white point in the display effect of the yellowish color temperature (2000K) are 0.75 times the G value and the B value in the color value parameter of the white point in the standard color temperature. Therefore, the color value parameter of the white point in the display effect of the 2000K color temperature is (255, 191, 191).

[0108] In some embodiments, the color value parameter of the white point in the display state of the non-standard color temperature can be a product of the coefficient of one or two color channel values in the color value parameter of the white point in the standard color temperature. For example, the R value and the G value in the color value parameter of the white point in the display effect of the bluish color temperature (9000K) are 0.75 times the R value and the G value in the color value parameter of the white point in the standard color temperature. Therefore, the color value parameter of the white point in the display effect of the 9000K color temperature is (191, 191, 255). The R value and the G value in the color value parameter of the white point in the display effect of the yellowish color temperature (2000K) are 0.75 times the G value and the B value in the color value parameter of the white point in the standard color temperature. Therefore, the color value parameter of the white point in the display effect of the 2000K color temperature is (255, 191, 191).

[0109] The above embodiments only illustrate the color value parameter of the white point in the non-standard color temperature state. The values involved are only used to show the change rule of the color value parameter of the white point and do not limit the actual application and the content of the present application. In the actual application process, the color value parameter of the white point in the non-standard state can be set according to the requirements.

[0110] In step S403, since the preset color value parameter of the white point is obtained at the preset reference color temperature, the ratio of the color value parameter of the white point to the preset color value parameter of the white point is taken as the current color temperature information, which can reflect the difference between the current color temperature information and the preset reference color temperature, and provide accurate current color temperature information for subsequent judgment of whether to provide brightness compensation.

[0111] In the present disclosure, the ratio of the color value parameter of the white point to the preset color value parameter of the white point is taken as the current color temperature information, which is simple to obtain and can obtain accurate current color temperature information, so that the terminal device can finally adjust the display brightness of the display screen to be adapted to the color temperature, and the visual use comfort of the user is improved.

[0112] According to an example embodiment, as shown in Figure 5 The display effect control method of the display screen in the present embodiment includes:

[0113] S501, obtaining a coefficient of a current color temperature of the display screen relative to a preset reference color temperature as current color temperature information;

[0114] S502, obtaining current display brightness information of the display screen;

[0115] S503, judging whether the current display brightness information and the current color temperature information match, if yes, executing step S504; if no, executing steps S505, S506, S507 and S508;

[0116] S504, if the current display brightness information and the current color temperature information match, maintaining the current display brightness of the display screen;

[0117] S505, if the current display brightness information and the current color temperature information do not match, obtaining hardware parameter information of the display screen;

[0118] S506, obtaining brightness compensation information based on the current color temperature information, the hardware parameter information and the preset reference color temperature;

[0119] S507, obtaining target display brightness information based on the brightness compensation information and the current display brightness information;

[0120] S508, adjusting the display brightness of the display screen based on the target display brightness information.

[0121] Among them, steps S501, S502, S503, S504 and S508 are the same as the embodiments in the above embodiments, and will not be repeated here.

[0122] In step S505, if the current display brightness information does not match the current color temperature information, it indicates that the current color temperature deviates from the preset reference color temperature, and the current display brightness of the display screen cannot be kept unchanged, and the current display brightness of the display screen needs to be compensated. Since there are various terminal devices, there are great differences in the hardware devices of the display screens. In order to ensure that the final display brightness conforms to the terminal device, the hardware parameter information of the display screen needs to be considered to obtain the hardware parameter information of the display screen.

[0123] In step S506, the preset reference color temperature is denoted as T, and the hardware parameter information of the display screen is denoted as t1, t2 and t3. For different display screens, the values of t1, t2 and t3 of the display screen can be different. The hardware parameter information can affect the display brightness determined by the performance of the display screen itself. The hardware parameter information includes the size of the unit board of the display screen, the resolution of the unit board, the pixel spacing, the LED pipe core and the like. For example, if the performance of the LED pipe core is good, the display brightness is guaranteed, and the values of t1, t2 and t3 are small. If the performance of the LED pipe core is poor, the display brightness cannot be guaranteed, and the values of t1, t2 and t3 are large. The ratio of the current color temperature information to the preset reference color temperature is denoted as a, and the brightness compensation information can be obtained through the formula t1*((1+a)*T) 2 +t2*(1+a)*T+t3. The brightness compensation information takes into account the difference between the current color temperature information and the preset reference color temperature, and also takes into account the influence of the hardware devices of the display screen. Therefore, the brightness compensation information can well compensate for the influence of the change of the color temperature on the display brightness of the display screen.

[0124] In step S507, the target display brightness information is determined by the brightness compensation information and the current display brightness information. The target display brightness information can be the sum of the brightness compensation information and the current display brightness information. The current display brightness information is denoted as bl, and the target display brightness information bl_r=bl+t1*((1+a)*T) 2 +t2*(1+a)*T+t3. The target display brightness information can also be the weighted sum of the brightness compensation information and the current display brightness information. The method for obtaining the target display brightness information can be determined according to the performance of the terminal device, and no unified regulation is made.

[0125] In the present disclosure, the hardware parameter information is added to the brightness compensation information considering the hardware differences of the display screen, so that the finally obtained target display brightness information is more in line with the display brightness requirements of the display screen of the terminal device, which improves the accuracy of the display brightness information and also improves the visual use comfort of the user.

[0126] According to an example embodiment, the display effect control method of the display screen in the present embodiment comprises:

[0127] The correspondence between the target display brightness information and the current color temperature information is established and stored.

[0128] If the current display brightness information does not match the current color temperature information, it indicates that the setting of the display screen brightness does not consider the influence of the current color temperature display effect, and therefore the display brightness of the display screen needs to be adjusted based on the current color temperature information, the current display brightness information is compensated, and the target display brightness information is obtained. The terminal device establishes and stores the correspondence between the target display brightness information and the current color temperature information, so that when the terminal device obtains the same color temperature information again, the display brightness of the display screen can be adjusted directly according to the stored correspondence, without the need for repeated calculation, and the waste of resources of the terminal device is avoided.
