Embodiment
Here will be described exemplary embodiment in detail, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or analogous key element.Execution mode described in following exemplary embodiment does not represent all execution modes consistent with the disclosure.On the contrary, they only with as in appended claims describe in detail, the example of apparatus and method that aspects more of the present disclosure are consistent.
Fig. 1 is a kind of flow chart adjusting the method for video screen brightness according to an exemplary embodiment, and the method is applied on television, and as shown in Figure 1, the method for this adjustment video screen brightness comprises the following steps.
In step S101, detect the test brightness value of video screen under the test condition preset.
The method of the present embodiment is applied in the test phase of television set, and TV all needed to test before dispatching from the factory, and test condition presets, and test condition defines the back facet current of the backlight that test uses, the picture of test use.The object of the present embodiment test makes the screen intensity between the multiple stage TV of same model basically identical, therefore, in test process, each TV arranges identical test condition, under same test condition, detect the test brightness value of video screen, namely test brightness value measures the brightness value of the video screen obtained under test conditions.
In the present embodiment, the optical sensor that can be arranged by the screen periphery of TV, detects the test brightness value of video screen under test conditions.If itself is provided with optical sensor around video screen, so directly utilize this light sensors, if there is no optical sensor around video screen, so will use method of the present disclosure, need to increase optical sensor at the screen periphery of TV.
In step s 102, the brightness range whether test brightness value belongs to default is judged.
The brightness range preset is the brightness value that the screen intensity of TV should have in this test condition, test condition measures the brightness value obtained under the test condition preset, if test brightness value does not belong to default brightness range, then perform step 103, if test brightness value belongs to default brightness range, then determine that the screen intensity of TV meets default brightness range, do not need the back facet current adjusting backlight.
In step s 103, when test brightness value does not belong to default brightness range, the back facet current of the backlight of adjustment TV, makes the screen intensity of TV meet default brightness range.
The back facet current of backlight determines therefore, to adjust the screen intensity of TV the back facet current of backlight in the present embodiment, make the screen intensity of TV meet default brightness range.Usual test brightness value lower than the brightness range preset, can now need the back facet current increasing backlight, to increase screen intensity.Certainly, test brightness value also may be greater than default brightness range, and test needs the back facet current reducing backlight, to reduce screen intensity.In the present embodiment, when there being the TV of multiple stage same model, for the brightness range that multiple stage TV arranges identical test condition and presets, can ensure that the screen intensity of multiple stage TV is consistent by adjustment, by consistent for the adjustment of the screen intensity of multiple stage TV, can to the unified optimization doing display aspect of multiple stage TV.
The method of the present embodiment, by detecting the test brightness value of video screen under the test condition preset, judge the brightness range whether test brightness value belongs to default, when test brightness value does not belong to default brightness range, the back facet current of the backlight of adjustment TV, makes the screen intensity of TV meet default brightness range.In described method, when there being the TV of multiple stage same model, being the brightness range that multiple stage TV arranges identical test condition and presets, can ensureing that the screen intensity of multiple stage TV is consistent.
Fig. 2 is a kind of flow chart adjusting the method for video screen brightness according to an exemplary embodiment, and as shown in Figure 2, the method for the adjustment video screen brightness of the present embodiment comprises the following steps:
In step s 201, the test brightness value of video screen under the test condition preset is detected.
In step S202, judge the brightness range whether test brightness value belongs to default.
In step S203, when test brightness value does not belong to default brightness range, the back facet current of the backlight of adjustment TV, makes the screen intensity of TV meet default brightness range.
The specific implementation of step S201-S203, with reference to associated description embodiment illustrated in fig. 1, repeats no more here.
In step S204, detect the intrinsic brilliance value of video screen.
What step S201-S203 described is how to adjust video screen brightness at test phase, after TV is sold, the operational phase of user, along with the increase of service time, the screen intensity of TV also can reduce, therefore, in the present embodiment, also in the operational phase of user, the intrinsic brilliance value of video screen can be detected.TV can according to the sense cycle preset, and periodically detect the intrinsic brilliance value of video screen, this sense cycle can be such as one month or one week.Or, when user thinks that video screen brightness is lower, control by remote controller etc. the intrinsic brilliance value that TV detects video screen.
In this step, the optical sensor that also can be arranged by the screen periphery of TV, detects the intrinsic brilliance value of video screen.
In step S205, judge that whether intrinsic brilliance value is lower than the brightness value preset.
If the intrinsic brilliance value of video screen is lower than the brightness value preset, then performs step S206, if the intrinsic brilliance value of video screen is not less than default brightness value, then determine not adjust the screen intensity of TV.
In step S206, when the low default brightness value of intrinsic brilliance value, increase the back facet current of the backlight of TV, make the screen intensity of TV meet default brightness range.
Because the intrinsic brilliance value of TV is lower than the brightness value preset, then need to increase back facet current, to increase the screen intensity of TV.
In the present embodiment, in the operational phase of TV, detect the intrinsic brilliance value of video screen, judge that whether intrinsic brilliance value is lower than the brightness value preset, when intrinsic brilliance value is lower than the brightness value preset, increase the back facet current of the backlight of TV, make the screen intensity of TV meet default brightness range.Described method, can make the screen intensity of TV remain at optimum range, bring user and better experience.
