Please refer to FIG. 3 , which is a schematic diagram of selecting a first specific display parameter combination according to an embodiment of the present invention.

In Scenario 1, in response to determining that the foreground application program is the first application program P1 and the current color gamut of the display 106 is the first color gamut G1, the processor 104 may select the first display parameter combination CO1 as the first specific display parameter combination .

In scenario 2, in response to determining that the foreground application program is the second application program P2, and the current color gamut of the display 106 is the second color gamut G2, the processor 104 may select the second display parameter combination CO2 as the first specific display parameter combination .

In scenario 3, in response to determining that the foreground application program is the first application program P1 and the current color gamut of the display 106 is the second color gamut G2, the processor 104 may select the third display parameter combination CO3 as the first specific display parameter combination .

In step S230, the processor 104 sets display parameters of the display 106 according to the first specific display parameter combination. For example, assume that the first specific display parameter combination is selected as the first display parameter combination CO1, and the first display parameter combination CO1 may include contrast A1 (for example, 50), color temperature A2 (for example, 5000K), Gamma A3 (for example, 0.5) , Hue A4 and Saturation A5. In this case, the processor 104 can set the display parameters such as contrast, color temperature, Gamma, hue, and saturation of the display 106 as contrast A1, color temperature A2, Gamma A3, hue A4, and saturation based on the first display parameter combination CO1. A5, but not limited to this.

As another example, assume that the first specific display parameter combination is selected as the second display parameter combination CO2, and the second display parameter combination CO2 may include contrast B1 (for example, 60), color temperature B2 (for example, 4000K), Gamma B3 (for example, 0.6), hue B4 and saturation B5. In this case, the processor 104 can set the display parameters of the display 106 as contrast B1, color temperature B2, Gamma B3, hue B4 and saturation respectively based on the second display parameter combination CO2. B5, but not limited to this.

In one embodiment, in response to determining that at least one of the foreground application and the current color gamut of the display 106 is changed, the processor 104 may select from the plurality of displays based on the changed foreground application and/or the current color gamut. A second specific display parameter combination is selected from the parameter combinations, and display parameters of the display 106 are set according to the second specific display parameter combination.

For example, when the current color gamut of the display 106 is the first color gamut G1, if the current foreground application program is the first application program P1, the processor 104 may correspondingly use the first display parameter combination CO1 as the first color gamut. A combination of display parameters is specified, and the display parameters of the display 106 are set accordingly. Afterwards, if the user switches the foreground application program from the first application program P1 to the second application program P2 (for example, manually selecting the second application program P2), the processor 104, for example, can correspondingly select the fourth display parameter combination CO4 as the second application program P2. Two specific display parameter combinations, and set the display parameters of the display 106 accordingly.

In addition, when the foreground application program is the second application program P2, if the current color gamut of the display 106 is the first color gamut G1, the processor 104 can correspondingly use the fourth display parameter combination CO4 as the first specific display parameter combination, and set the display parameters of the display 106 accordingly. Afterwards, if the user switches the current color gamut of the display 106 from the first color gamut G1 to the second color gamut G2, the processor 104 may correspondingly select the second display parameter combination CO2 as the second specific display parameter combination, And set the display parameters of the display 106 accordingly.

As can be seen from the above, the embodiment of the present invention can adjust the display parameters of the display 106 accordingly according to the current foreground application and the current color gamut of the display 106 when the user switches between different foreground applications. In this way, the display situation of the display 106 can be automatically adjusted to meet the user's use situation, thereby improving user experience.

In addition, the present invention further proposes a mechanism for modifying the contents of the above-mentioned mapping table according to the user's habit, so as to make more appropriate adjustments to the display situation of the display 106 . The relevant instructions are as follows.

For ease of description, it is assumed that the first display parameter combination CO1 is the first specific display parameter combination selected by the processor 104 in step S220 , but it is not limited thereto.

In step S410, the processor 104 accumulates a first accumulated usage time of the first display parameter combination CO1. In the embodiment of the present invention, the first cumulative use time of the first display parameter combination CO1 is, for example, the sum of the use time since the first display parameter combination CO1 was established, but it is not limited thereto.

Afterwards, in step S420, in response to determining that the display parameters of the display 106 are set to correspond to another display when the foreground application is the first application P1 and the current color gamut of the display 106 is the first color gamut G1 For a parameter combination, the processor 104 accumulates a second accumulated usage time of the other display parameter combination.

For example, assume that the first display parameter combination CO1 includes contrast A1, color temperature A2, Gamma A3, hue A4, and saturation A5, and the user's foreground application is the first application P1, and the current color gamut of the display 106 is In the case of the first color gamut G1, the display parameters of the display 106 are adjusted to contrast A1 ′, color temperature A2, Gamma A3, hue A4, and saturation A5. In this case, the processor 104 may regard the contrast A1', the color temperature A2, the Gamma A3, the hue A4 and the saturation A5 as the other display parameter combination (hereinafter referred to as the display parameter combination CO1'), and accumulate the other display parameter combination One displays the second accumulated usage time of the parameter combination CO1'.

Next, in step S430, in response to determining that the second cumulative usage time exceeds the first cumulative usage time, the processor 104 replaces the first display parameter corresponding to the first application program AP1 and the first color gamut G1 with the display parameter combination CO1' Combine CO1. Specifically, if the second cumulative usage time exceeds the first cumulative usage time, it means that when the foreground application program is the first application program P1 and the current color gamut of the display 106 is the first color gamut G1, the user It may be more preferable to use the display parameter combination CO1 ′ to set the display parameters of the display 106 .

Therefore, the processor 104 can correspondingly replace the first display parameter combination CO1 originally corresponding to the first application program AP1 and the first color gamut G1 with the display parameter combination CO1 ′. In this case, the contents of Table 1 can be updated accordingly to the contents exemplified in Table 2 below. Show parameter combination CO1' 1st App + 1st Color Gamut The second display parameter combination CO2 2nd App + 2nd Color Gamut The third display parameter combination CO3 1st app + 2nd gamut The fourth display parameter combination CO4 2nd app + 1st gamut … … Table 2

Based on this, when the processor 104 later determines that the foreground application program is the first application program P1, and the current color gamut of the display 106 is the first color gamut G1, the processor 104 can select the display parameter combination CO1' to set the display of the display 106 parameter.

It can be known from the above that the embodiment of the present invention can further update the contents of the mapping table according to the user's operating preference/habit, so that the display parameters of the display 106 can be adjusted to be more in line with the user's preference/habit.

In addition, although it is assumed in FIG. 4 that the first display parameter combination CO1 is the first specific display parameter combination selected by the processor 104 in step S220, in other embodiments, those skilled in the art should follow the above teachings And correspondingly, the operation mechanism when the first specific display parameter combination selected by the processor 104 in step S220 is another display parameter combination.

To sum up, the embodiment of the present invention can adjust the display parameters of the display accordingly according to the current foreground application and the current color gamut of the display when the user switches between different foreground applications. In this way, the display situation of the display can be automatically adjusted to meet the user's use situation, thereby improving user experience. In addition, the embodiment of the present invention can further update the content of the mapping table according to the user's operating preference/habit, so that the display parameters of the display can be adjusted to be more in line with the user's preference/habit.
