[0098] Here, the exemplary embodiments will be described in detail, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0099] Currently, the dark mode of a terminal device is usually achieved by inverting the L color channel in the Lab color space. For example, black text is inverted into white text, or a white background is inverted into a black background. And there is usually only one display mode in the dark mode, and it cannot be adaptively adjusted according to the ambient light intensity. However, the present disclosure can convert the brightness of the display screen according to the light intensity of the environment where the terminal device is currently located, so as to obtain a target screen suitable for the current environment in a specified display mode, which can improve the flexibility of display adjustment and the comfort of the display interface.

[0100] Figure 1 It is a flowchart of a display control method shown according to an exemplary embodiment. As Figure 1 shown, the method may include the following steps:

[0101] In step S101, when the terminal device turns on a specified display mode, detect the light intensity of the environment where the terminal device is currently located.

[0102] For example, the execution subject of the present disclosure may be a terminal device. Among them, the terminal device may include, but is not limited to, mobile terminals such as mobile phones, laptop computers, digital broadcast receivers, PDAs (Personal Digital Assistants), PADs (Tablet Computers), PMPs (Portable Multimedia Players), vehicle-mounted terminals (such as vehicle-mounted navigation terminals), etc., and fixed terminals such as digital TVs, desktop computers, etc. First, it is possible to detect whether the terminal device has enabled a specified mode, where the specified mode may be, for example, the dark mode. If it is detected that the terminal device has enabled the specified display mode, then the light intensity of the environment where the terminal device is currently located can be directly detected through the photosensitive component provided on the terminal device, or the light intensity of the environment where the terminal device is currently located can be indirectly obtained based on the screen backlight brightness of the terminal device. The present disclosure does not make specific limitations on this.

[0103] In step S102, according to the preset corresponding relationship, determine the conversion parameter corresponding to the light intensity.

[0104] Exemplarily, the corresponding relationship between the light intensity and the conversion parameter can be preset. After obtaining the light intensity of the environment where the terminal device is currently located, the conversion parameter corresponding to the light intensity can be obtained according to the preset corresponding relationship. It should be noted that the corresponding relationship can be a corresponding relationship table established in advance between the intensity interval and the conversion parameter. For example, it can be as shown in Table 1, where DBV is used to indicate the screen backlight brightness of the terminal device, and K and B are conversion parameters. After detecting the light intensity, it is possible to first determine the intensity interval to which the light intensity belongs, and then look up the conversion parameter corresponding to the intensity interval to which the light intensity belongs in the corresponding relationship table. The corresponding relationship can also be a corresponding relationship function established in advance between the light intensity and the conversion parameter. After detecting the light intensity, the light intensity can be substituted into the corresponding relationship function to obtain the conversion parameter corresponding to the light intensity. The corresponding relationship can also be a corresponding relationship model trained in advance between the light intensity and the conversion parameter. After detecting the light intensity, the light intensity can be used as the input of the corresponding relationship model, and the conversion parameter corresponding to the light intensity is output.

[0105] Strength range Illumination intensity (lux) DBV K B 1 0-5 0-160 0.7059 0 2 5-25 160-600 0.5882 0.1961 3 25-800 600-1200 0.6471 0.2549 4 800-2000 1200-2400 0.6275 0.3137 5 2000+ 2400-8191 0.6863 0.3137

[0106] Table 1

[0107] In step S103, according to the conversion parameter, convert the value of the picture to be displayed in the HSV (English: Hue, Saturation, Value; Chinese: Hue, Saturation, Brightness) color space to obtain the target picture corresponding to the specified display mode, and draw the target picture on the display interface of the terminal device.

[0108] Exemplarily, after obtaining the conversion parameter corresponding to the light intensity, the lightness of the picture to be displayed can be converted in the HSV color space according to the conversion parameter, so as to obtain the target picture corresponding to the specified display mode. The picture to be displayed can be understood as the picture that the terminal device currently needs to display. Specifically, the lightness of the picture to be displayed can be reduced by converting the V color channel of the picture to be displayed in the HSV color space according to the conversion parameter, or the gray level of the picture to be displayed can be directly changed according to the conversion parameter to reduce the lightness of the picture to be displayed. The present disclosure does not make specific limitations on this. After that, the target picture can be drawn on the display interface of the terminal device. Specifically, the target picture can be drawn by means of hardware acceleration drawing or software drawing. The target picture can include multiple layers, and each layer can correspond to different controls. Correspondingly, the corresponding layers can be drawn on the display interface of the terminal device through the controls corresponding to each layer to display the target picture on the display interface.

[0109] In this way, when the terminal device is in the specified display mode, the lightness of the picture displayed on the display interface can be changed according to the light intensity of the environment where the terminal device is located, which can improve the flexibility of display adjustment and the comfort of the display interface.

[0110] In summary, the present disclosure first detects the light intensity of the environment where the terminal device is currently located when the terminal device enables the specified display mode, and obtains the conversion parameter corresponding to the light intensity according to the preset corresponding relationship. After that, the lightness of the picture to be displayed is converted according to the conversion parameter, so as to obtain the target picture corresponding to the specified display mode, and the target picture is drawn on the display interface of the terminal device. The present disclosure converts the lightness of the picture to be displayed according to the light intensity of the environment where the terminal device is currently located, so as to obtain the target picture that adapts to the current environment in the specified display mode, which can improve the flexibility of display adjustment and the comfort of the display interface.

[0111] Figure 2 It is a flowchart of another display control method shown according to an exemplary embodiment. As Figure 2 shown, step S103 can be implemented through the following steps:

[0112] In step S1031, the picture to be displayed is converted from the RGB color space to the HSV color space to obtain the first intermediate picture.

[0113] In step S1032, the V color channel of the first intermediate picture is converted according to the conversion parameter to obtain the second intermediate picture.

[0114] In step S1033, the second intermediate picture is converted from the HSV color space to the RGB color space to obtain the target picture.

[0115] Exemplarily, usually, the terminal device uses the RGB (English: Red, Green, Blue; Chinese: Red, Green, Blue) color space. In order to directly adjust the brightness of the picture to be displayed, after obtaining the conversion parameters, the picture to be displayed can be converted from the RGB color space to the HSV color space to obtain a first intermediate picture. Then, the V color channel of the first intermediate picture can be converted according to the conversion parameters to change the brightness of the first intermediate picture to obtain a second intermediate picture. Finally, the second intermediate picture is converted from the HSV color space back to the RGB color space to obtain the target picture.

[0116] In an application scenario, the conversion parameters include: a first conversion parameter and a second conversion parameter. One implementation of step S1032 can be:

[0117] Invert the value of the first intermediate picture on the V color channel.

[0118] Multiply the inversion result by the first conversion parameter, and use the sum of the multiplication result and the second conversion parameter as the value of the second intermediate picture on the V color channel.

[0119] Exemplarily, the conversion parameters can include: a first conversion parameter and a second conversion parameter. After converting the picture to be displayed from the RGB color space to the HSV color space, the value of the first intermediate picture on the V color channel can be obtained, and the value of the first intermediate picture on the V color channel can be inverted to obtain an inversion result. Then, the inversion result can be multiplied by the first conversion parameter, and the sum of the multiplication result and the second conversion parameter can be used as the value of the second intermediate picture on the V color channel. The above steps can be represented by formula 1, for example:

[0120] V′ = K(1 - V) + B (Formula 1)

[0121] Where, V′ is the value of the second intermediate picture on the V color channel, V is the value of the first intermediate picture on the V color channel, K is the first conversion parameter, and B is the second conversion parameter.

[0122] Specifically, taking the first conversion parameter K = 0.6, the second conversion parameter B = 0.2, and the value of the first intermediate picture on the V color channel V = 0.7 as an example, the value of the second intermediate picture on the V color channel V′ = 0.6*(1 - 0.7) + 0.2 = 0.38.

[0123] It should be noted that as shown in Table 2, the preset gray level of black in the specified display mode and the preset gray level of white in the specified display mode can be determined through experiments in each intensity interval, so that the contrast between black and white in the specified display mode is within the preset range, thus ensuring the comfort of the display interface. Among them, when the values of the R color channel, G color channel, and B color channel of a certain color in the RGB color space are equal and all are X, the gray level of this color is X. For example: the values of the R color channel, G color channel, and B color channel of white in the RGB color space are equal and all are 255, then the gray level of white is 255. Among them, the preset range of the contrast can be 7 - 12. For example: in the first intensity interval in Table 2, the preset gray level of white in the specified display mode is 0, and the preset gray level of black in the specified display mode is 180, then the contrast between black and white in the specified display mode in the first intensity interval can be obtained as 10, which is within the preset range. Another example: in the second intensity interval in Table 2, the preset gray level of white in the specified display mode is 50, and the preset gray level of black in the specified display mode is 200, then the contrast between black and white in the specified display mode in the second intensity interval can be obtained as 7.6, which is also within the preset range.

[0124] After that, for each intensity interval, the gray level of black in the normal mode can be converted to the HSV color space to obtain the value of the V color channel of black in the normal mode (i.e., the V value in Formula 1), and the preset gray level of black in the specified display mode can be converted to the HSV color space to obtain the value of the V color channel of black in the specified display mode (i.e., the V' value in Formula 1). And the gray level of white in the normal mode can be converted to the HSV color space to obtain the value of the V color channel of white in the normal mode (i.e., the V value in Formula 1), and the preset gray level of white in the specified display mode can be converted to the HSV color space to obtain the value of the V color channel of white in the specified display mode (i.e., the V' value in Formula 1). Further, the value of the V color channel of black in the normal mode and the value of the V color channel of black in the specified display mode can be substituted into Formula 1 to obtain Relationship 1. And the value of the V color channel of white in the normal mode and the value of the V color channel of white in the specified display mode can be substituted into Formula 1 to obtain Relationship 2. According to Relationship 1 and Relationship 2, the conversion parameters corresponding to this intensity interval can be obtained, that is, K and B in Formula 1.

[0125]

[0126] Table 2

[0127] Taking the first intensity range in Table 2 as an example, the gray level of black in the normal mode is 0. After converting to the HSV color space, the value of the corresponding V color channel is 0 (i.e., V = 0). As can be seen from Table 2, the gray level of black in the specified display mode is 180. After converting to the HSV color space, the value of the corresponding V color channel is 0.7059 (i.e., V' = 0.7059). Substituting the value of the V color channel of black in the normal mode (i.e., V = 0) and the value of the V color channel in the specified display mode (i.e., V' = 0.7059) into Equation 1, we can get:

[0128] 0.7095 = K(1 - 0) + B (1)

[0129] The gray level of white in the normal mode is 255. After converting to the HSV color space, the value of the corresponding V color channel is 1 (i.e., V = 1). As can be seen from Table 2, the gray level of white in the specified display mode is 0. After converting to the HSV color space, the value of the corresponding V color channel is 0 (i.e., V' = 0). Substituting the value of the V color channel of white in the normal mode (i.e., V = 1) and the value of the V color channel in the specified display mode (i.e., V' = 0) into Equation 1, we can get:

[0130] 0 = K(1 - 1) + B (2)

[0131] According to Equation (1) and Equation (2), we can get: K = 0.7095, B = 0.

[0132] Figure 3 is a flowchart of another display control method shown according to an exemplary embodiment. As Figure 3 shown, step S102 can be implemented through the following steps:

[0133] In step S1021, in multiple intensity ranges, determine the current intensity range to which the light intensity belongs.

[0134] In step S1022, determine the duration for which the light intensity remains in the current intensity range.

[0135] In step S1023, if the duration is greater than or equal to the specified duration threshold, determine the conversion parameter according to the corresponding relationship and the current intensity range.

[0136] Exemplarily, the light intensity can be divided into multiple intensity intervals in advance. After detecting the light intensity of the environment where the terminal device is currently located, the current intensity interval to which the light intensity belongs can be determined among the multiple intensity intervals, and further, the duration for which the light intensity remains in the current intensity interval can be determined. If the duration is greater than or equal to the specified duration threshold, indicating that the light intensity is stable in the current intensity interval, then the conversion parameter can be determined according to the corresponding relationship and the current intensity interval. If the duration is less than the specified duration threshold, indicating that the light intensity is not stable, then the current conversion parameter can be kept unchanged. Among them, the specified duration threshold can be, for example, 2s.

[0137] Specifically, taking the intensity intervals including 0 - 800 lux and 800 - 2000 lux, the light intensity of 300 lux, and the specified duration threshold of 2s as an example, it can be determined that the current intensity interval is 0 - 800 lux. If the duration for which the light intensity remains within 0 - 800 lux is 3s, indicating that the light intensity is stable within 0 - 800 lux, then the conversion parameter can be determined according to the corresponding relationship and the current intensity interval. If the duration for which the light intensity remains within 0 - 800 lux is 1s, indicating that the light intensity has not yet stabilized within 0 - 800 lux, then the current conversion parameter can be kept unchanged.

[0138] Figure 4 is a flowchart of another display control method shown according to an exemplary embodiment, as Figure 4 shown, step S102 can also be implemented through the following steps:

[0139] In step S1024, among the multiple intensity intervals, determine the current intensity interval to which the light intensity belongs, and the historical intensity interval to which the historical light intensity belongs. The historical light intensity is the light intensity of the environment where the terminal device was previously located.

[0140] In step S1025, if the current intensity interval is different from the historical intensity interval, and the light intensity does not belong to the protection interval of the current intensity interval, determine the conversion parameter according to the corresponding relationship and the current intensity interval.

[0141] In step S1026, if the current intensity interval is different from the historical intensity interval, and the light intensity belongs to the protection interval of the current intensity interval, determine the conversion parameter according to the corresponding relationship and the historical intensity interval.

[0142] Exemplarily, the light intensity can be divided into multiple intensity intervals in advance, and a protection interval can be set in each intensity interval. Taking the intensity intervals including 0 - 800 lux and 800 - 2000 lux as an example, 700 - 800 lux can be set as the protection interval for 0 - 800 lux, and 800 - 1000 lux can be set as the protection interval for 800 - 2000 lux. After detecting the light intensity of the environment where the terminal device is currently located, in multiple intensity spaces, the current intensity interval to which the light intensity belongs and the historical intensity interval to which the historical light intensity belongs can be determined. Among them, the historical light intensity can be understood as the light intensity of the environment where the terminal device was previously located.

[0143] If the current intensity interval is different from the historical intensity interval, and the light intensity does not belong to the protection interval of the current intensity interval, it means that the light intensity is stable in the current intensity interval. Then, the conversion parameter can be determined according to the corresponding relationship and the current intensity interval. If the current intensity interval is different from the historical intensity interval, and the light intensity belongs to the protection interval of the current intensity interval, it means that the light intensity has not yet stabilized in the current intensity interval and may jump between the current intensity interval and the historical intensity interval. Then, the conversion parameter is determined according to the corresponding relationship and the historical intensity interval. In this way, by setting a protection interval in each intensity interval, the problem that the light intensity jumps at the boundary between intensity intervals, resulting in frequent switching of the brightness of the displayed screen, can be avoided, and the display stability can be improved.

[0144] Specifically, taking the intensity intervals including 0 - 800 lux and 800 - 2000 lux, 700 - 800 lux as the protection interval for 0 - 800 lux, 800 - 1000 lux as the protection interval for 800 - 2000 lux, and the historical light intensity being 1000 lux as an example, the historical intensity interval can be determined to be 800 - 2000 lux. If the light intensity is 500 lux, the current intensity interval can be determined to be 0 - 800 lux, which is different from the historical intensity interval, and the light intensity does not belong to the protection interval 700 - 800 lux of 0 - 800 lux. Then, the conversion parameter can be determined according to the corresponding relationship and the current intensity interval 0 - 800 lux. If the light intensity is 750 lux, the current intensity interval can be determined to be 0 - 800 lux, which is different from the historical intensity interval, and the light intensity belongs to the protection interval (700 - 800 lux) of 0 - 800 lux. Then, the conversion parameter can be determined according to the corresponding relationship and the historical intensity interval 800 - 2000 lux.

[0145] Figure 5 is a flowchart of another display control method shown according to an exemplary embodiment, as Figure 5 shown, step S102 can also be implemented through the following steps:

[0146] In step S1027, among multiple intensity ranges, determine the current intensity range to which the light intensity belongs and the historical intensity range to which the historical light intensity belongs, where the historical light intensity is the light intensity of the environment where the terminal device was previously located.

[0147] In step S1028, determine the current conversion parameter according to the correspondence relationship and the current intensity range, and determine the historical conversion parameter according to the correspondence relationship and the historical intensity range.

[0148] In step S1029, according to the preset rule, determine multiple conversion parameters arranged in sequence between the historical conversion parameter and the current conversion parameter.

[0149] Correspondingly, an implementation manner of step S103 can be:

[0150] Successively convert the lightness of the screen to be displayed in the HSV color space according to each conversion parameter to obtain the target screen, and draw the target screen on the display interface.

[0151] Exemplarily, after detecting the light intensity of the environment where the terminal device is currently located, it is possible to determine the current intensity range to which the light intensity belongs and the historical intensity range to which the historical light intensity belongs among multiple intensity ranges. Here, the historical light intensity can be understood as the light intensity of the environment where the terminal device was previously located. Then, the current conversion parameter can be determined according to the correspondence relationship and the current intensity range, and the historical conversion parameter can be determined according to the correspondence relationship and the historical intensity range. Among them, the current conversion parameter can include the first current conversion parameter and the second current conversion parameter, and the historical conversion parameter can include the first historical conversion parameter and the second historical conversion parameter.

[0152] Furthermore, it is possible to determine multiple conversion parameters arranged in sequence between the historical conversion parameter and the current conversion parameter according to the preset rule. Among them, each conversion parameter includes the first conversion parameter and the second conversion parameter. Specifically, the preset rule can extract multiple conversion parameters at a specified step value within the range from the historical conversion parameter to the current conversion parameter, where the specified step value can be, for example, 0.05. The preset rule can also be to extract a specified number of conversion parameters at equal intervals within the range from the historical conversion parameter to the current conversion parameter, where the specified number can be, for example, 29. Multiple conversion parameters can be obtained, for example, according to Formula 2 and Formula 3:

[0153]

[0154]

[0155] where, K n is the nth first conversion parameter, K N+1is the first current conversion parameter, K0 is the first historical conversion parameter, and N is the specified quantity. B n is the nth second conversion parameter, B N+1 is the second current conversion parameter, and B0 is the second historical conversion parameter.

[0156] Taking the specified quantity as 9, the first historical conversion parameter as 0.5, the second historical conversion parameter as 0.2, the first current conversion parameter as 0.6, and the second current conversion parameter as 0.1 as an example, the 3rd first conversion parameter is Correspondingly, the 3rd second conversion parameter is

[0157] Finally, the brightness of the picture to be displayed can be sequentially converted in the HSV color space according to each conversion parameter to obtain the target picture corresponding to each conversion parameter, and the target picture is drawn on the display interface. Specifically, the brightness of the picture to be displayed can be sequentially converted according to each conversion parameter at a preset frequency to obtain the target picture corresponding to each conversion parameter, and the target picture is drawn on the display interface. Among them, the preset frequency can be, for example, 1s, that is, the brightness of the picture to be displayed is adjusted once per second. It is also possible to sequentially convert the brightness of the picture to be displayed according to each conversion parameter at the same time interval within a specified duration according to a specified number of times to obtain the target picture corresponding to each conversion parameter, and the target picture is drawn on the display interface. Among them, the specified duration can be, for example, 30s, and the specified number of times can be, for example, 10 times, that is, within 30s, at a time interval of 3s, through 10 adjustments, the conversion of the brightness of the picture to be displayed corresponding to the historical conversion parameter to the picture to be displayed corresponding to the current conversion parameter is completed. The present disclosure does not make specific limitations on this. In this way, the brightness of the picture to be displayed is sequentially converted according to multiple conversion parameters, so that the brightness of the picture to be displayed gradually changes according to a certain gradient, and the transition of the brightness of the picture to be displayed can be realized more naturally, improving the comfort of the display interface.

[0158] Figure 6 is a flowchart of another display control method shown according to an exemplary embodiment, as Figure 6 shown, step S103 can also be implemented through the following steps:

[0159] In step S1034, determine the value of the text part in the picture to be displayed in the RGB color space.

[0160] In step S1035, if the values of the text part on the R color channel, the G color channel, and the B color channel are all less than the preset threshold, adjust the text part according to the minimum value of the text part on the R color channel, the G color channel, and the B color channel to obtain the adjusted picture to be displayed.

[0161] In step S1036, the brightness of the adjusted display screen to be displayed is converted in the HSV color space according to the conversion parameters to obtain the target screen.

[0162] Exemplarily, before converting the brightness of the display screen to be displayed according to the conversion parameters, the values of the text part in the display screen to be displayed in the RGB color space can be obtained first. If the values of the text part on the R color channel, the G color channel, and the B color channel are all less than the preset threshold, it means that the color of the text part is close to black but may not be black or gray. If the brightness of the text part is directly converted according to the values of the text part in the RGB color space, the converted text may become a color other than white or gray, affecting the user's reading. Among them, the preset threshold can be 50, for example. Therefore, the text part can be adjusted according to the minimum value of the text part on the R color channel, the G color channel, and the B color channel to obtain the adjusted display screen to be displayed. Then, the brightness of the adjusted display screen to be displayed is further converted according to the conversion parameters to obtain the target screen.

[0163] Specifically, the minimum value of the text part on the R color channel, the G color channel, and the B color channel can be determined first, and the values of the text part on the R color channel, the G color channel, and the B color channel are all adjusted to this minimum value. Taking the preset threshold as 50, the value of the text part on the R color channel as 23, the value on the G color channel as 27, and the value on the B color channel as 32 as an example, then the minimum value can be determined as 23, and the values of the text part on the R color channel, the G color channel, and the B color channel are all adjusted to 23. In this way, when the values of the text part on the R color channel, the G color channel, and the B color channel are all less than the preset threshold, the values of the text part on the R color channel, the G color channel, and the B color channel are first adjusted to the minimum value of the text part on the R color channel, the G color channel, and the B color channel, and then the brightness of the adjusted display screen to be displayed is converted according to the conversion parameters, which can ensure that the converted text is gray or white and will not show other colors, improving the accuracy of the conversion.

[0164] Figure 7 It is a flowchart of another display control method shown according to an exemplary embodiment. As Figure 7 shown, one implementation manner of step S102 can be:

[0165] According to the corresponding relationship, determine the conversion parameters and the picture mask layer corresponding to the light intensity.

[0166] Correspondingly, step S103 can be implemented in the following manner:

[0167] In step S1037, determine the picture part and other parts in the picture to be displayed.

[0168] In step S1038, process the picture part according to the picture mask layer, and convert the brightness of other parts according to the conversion parameters to obtain the target picture.

[0169] In step S1039, draw the target picture on the display interface.

[0170] Exemplarily, after detecting the light intensity of the environment where the terminal device is currently located, the conversion parameters and the picture mask layer corresponding to the light intensity can be determined according to the corresponding relationship. Among them, the picture mask layer can be understood as a pre-set mask layer that can reduce the brightness of the picture. It should be noted that the corresponding relationship can be a pre-established corresponding relationship table between the light intensity, the conversion parameters, and the picture mask layer, as shown in Table 3. After detecting the light intensity, the conversion parameters and the picture mask layer corresponding to the light intensity can be found in the corresponding relationship table. The corresponding relationship can also be a pre-trained corresponding relationship model between the light intensity, the conversion parameters, and the picture mask layer. After detecting the light intensity, the light intensity can be used as the input of the corresponding relationship model, and the conversion parameters and the picture mask layer corresponding to the light intensity can be output. The present disclosure does not make specific limitations on this.

[0173] Furthermore, the picture part and other parts in the picture to be displayed can be determined, and then the picture mask layer can be covered on the picture part to reduce the brightness of the picture part, and the brightness of other parts can be converted according to the conversion parameters, so as to obtain the target picture after processing the picture part and other parts respectively. Finally, draw the target picture on the display interface to make the brightness of the picture displayed on the display interface uniform, which can improve the comfort of the display interface.

[0174] In summary, the present disclosure first detects the light intensity of the environment where the terminal device is currently located when the terminal device turns on the specified display mode, and obtains the conversion parameters corresponding to the light intensity according to the preset corresponding relationship. Then, the brightness of the picture to be displayed is converted according to the conversion parameters, so as to obtain the target picture corresponding to the specified display mode, and the target picture is drawn on the display interface of the terminal device. The present disclosure converts the brightness of the picture to be displayed according to the light intensity of the environment where the terminal device is currently located, so as to obtain the target picture adapted to the current environment in the specified display mode, which can improve the flexibility of display adjustment and the comfort of the display interface.
