DETAILED DESCRIPTION

Herein, the exemplary embodiments will be explained in detail, and the examples thereof are shown in the figures. When the following description relates to the figures, the same number in different figures indicates the same or similar elements, except for other indications. The embodiment method described in the following exemplary embodiments does not represent all the embodiment methods that are consistent with the present disclosure. In contrast, they are only examples of the device and the method described in the attached claims and consistent with some aspects of the present disclosure.

FIG. 1 is a scene schematic diagram provided by an embodiment of the present disclosure. A television 1 is included in FIG. 1. An external device interface (e.g., a USB interface) is arranged on the television 1, through which a user can connect an external device 2 and expand functions of the television 1, such as receiving some particular channel signals or video sources, etc.

Wherein, FIG. 1 merely is a scene schematic diagram of the present disclosure. The specific type, number and correspondence of the television 1 and the external device 2 connected to the television 1 are not limited to the specific methods disclosed in FIG. 1. For instance, the number of the external device 2 may be two or more than two, a method to connect the external device 2 and the television 1 can be a wireless connection, etc, which can be selected by one of ordinary skilled in the art according to his/her own requirements, and are not limited in the present disclosure.

FIG. 2 is a flow schematic diagram of a method for controlling television energy efficiency provided by an embodiment of the present disclosure. As shown in FIG. 2, the method for controlling energy efficiency of the television includes the following steps.

In step S100, a cache address of frame data input by an external device is acquired from an application layer.

In the embodiment of the present disclosure, after the external device is connected to the television through the external device interface, frame data in the external device is transmitted to an external device adaptation layer via the external device interface, wherein the external device adaptation layer transmits the frame data to a buffer to perform cache and transmits the cache address of the frame data in the buffer to the application layer. The cache address is transmitted to a display adaptation layer after the application layer receives the cache address of the frame data, and the display adaptation layer searches for frame data corresponding to the cache address in the buffer according to the cache address, thereby displaying a corresponding image on a display screen according to the frame data.

Although according to the program set by the external device, frame data output by the external device cannot be directly acquired in a hardware layer and an adaptation layer since the frame data is in a packaging state in the hardware layer and the adaptation layer, the cache address in the buffer will be transmitted to the application layer after the external device adaptation layer transmits the frame data to the buffer to perform cache. Therefore, in the embodiment of the present disclosure, the cache address of the frame data input by the external device can be acquired from the application layer.

In step S200, frame data corresponding to the cache address is searched for.

Since the frame data in the buffer has a one-to-one mapping relationship with the cache address, the frame data can be uniquely determined after the cache address is determined. At this time, since the cache address of the frame data has been acquired in the application layer, the corresponding frame data can be searched for in the buffer according to the cache address. Wherein, the method to search for the frame data is not specifically limited in the embodiment of the present disclosure, and thus one of ordinary skilled in the art can select different search methods according to actual requirements, which should fall into the protection scope of the present disclosure.

In step S300, energy consumption parameter information is extracted from the frame data.

The energy efficiency of the television is a ratio of the area of the display screen to the energy consumption. In a case where the area of the display screen is fixed, only the energy consumption of the television is reduced to improve the energy efficiency of the television. Since the quality of the image displayed on the display screen can influence the energy consumption of the television (the higher the quality of the image, the higher the energy consumption of the television), the energy consumption of the television can be determined according to information (i.e., frame data) of the image displayed on the display screen, so as to execute a corresponding energy efficiency control strategy for the television.

In the embodiment of the present disclosure, the frame data includes detailed information of the image, including luminance, contrast, resolution, pixel value, etc. Since it needs to control the energy efficiency of the television according to the frame data in the embodiment of the present disclosure, information (i.e., energy consumption parameter information) related to the energy consumption is extracted from the frame data.

In step S400, energy efficiency control is performed for the television according to the energy consumption parameter information.

In the embodiment of the present disclosure, the corresponding energy efficiency control strategy can be executed for the television according to energy consumption parameter information only after the energy consumption parameter information is determined.

For instance, if the energy consumption parameter information is larger than the preset energy consumption parameter information threshold value, it is indicated that the current energy consumption of the television has exceed the set energy consumption standard, and thus the current energy consumption of the television is reduced to realize energy efficiency control for the television. If the energy consumption parameter information is equal to or smaller than the preset energy consumption parameter information threshold value, it is indicated that the current energy consumption of the television does not exceed the set energy consumption standard, and thus the current energy consumption state of the television is maintained. Wherein, the specific method to reduce the current energy consumption of the television is not limited in the embodiment of the present disclosure, and thus one of ordinary skilled in the art can reduce the power consumption of the corresponding devices of the television according to actual requirements, which should fall into the protection scope of the present disclosure.

In another embodiment of the present disclosure, as shown in FIG. 3, step S300 of the embodiment shown in FIG. 2 may include the following step:

- In step S301, luminance data in the frame data is extracted as the energy consumption parameter information.

The frame data includes detailed information of the image displayed on the display screen, including luminance, contrast, resolution, pixel value, etc. Since the luminance of the image has a great influence on the energy consumption of the television, luminance data in the frame data can be extracted as the energy consumption parameter information in the embodiment of the present disclosure.

Of course, the above content is only a specific implementation method illustrated in the present disclosure. One of ordinary skilled in the art can extract other information in the frame data as energy consumption parameter information according to actual requirements, which should fall into the protection scope of the present disclosure. For example, resolution data in the frame data can be extracted as energy consumption parameter information.

In another embodiment of the present disclosure, as shown in FIG. 4, step S400 of the embodiment shown in FIG. 3 may include the following step:

- In step S401, whether the luminance data is larger than a preset luminance threshold value is determined.

It is easily understood that if the current energy efficiency of the television conforms to the energy efficiency standard, it does not need to perform energy efficiency control for the television; if the current energy efficiency of the television does not conform to the energy efficiency standard, it needs to reduce the current energy consumption of the television. That is, the energy efficiency control is performed for the television to make it meet the energy efficiency standard.

In the embodiment of the present disclosure, a luminance threshold value is set according to the energy efficiency standard of the television, i.e., serving the luminance threshold value as a standard to determine whether it is necessary to perform energy efficiency control for the television. Specifically, it is determined whether the luminance data is larger than the preset luminance threshold value, and if the luminance data is larger than the preset luminance threshold value, step S402 is performed; otherwise, the flow ends.

In step S402, energy efficiency control is performed for the television.

The energy efficiency of the television is a ratio of the area of the display screen to the energy consumption. In a case where the area of the display screen is fixed, only the energy consumption of the television is reduced to improve the energy efficiency of the television. In the embodiment of the present disclosure, the energy efficiency of the television can be improved by a method of reducing the energy consumption of the television, thereby controlling the energy efficiency of the television in a standard level and realizing the energy efficiency control for the television. Wherein, the specific method to reduce the energy consumption of the television is not limited in the embodiment of the present disclosure, and thus one of ordinary skilled in the art can use different technical means according to actual requirements, which should fall into the protection scope of the present disclosure.

Since the luminance of the image has a great influence on the energy consumption of the television, the accuracy of the energy efficiency control can be improved by using luminance data in the frame data as a standard to determine whether it is necessary to perform the energy efficiency control.

In another embodiment of the present disclosure, as shown in FIG. 5, step S402 of the embodiment shown in FIG. 4 may include the following step:

- In step S4021, luminance data in the frame data is adjusted to the luminance threshold value.

As for the television, the energy consumption mainly depends on the display screen, i.e., reduction of the whole energy consumption of the television means to reduction of the energy consumption of the display screen. Wherein, the energy consumption of the display screen is mainly used for displaying an image, and thus the energy consumption of the display screen can be reduced by adjusting the image displayed by the display screen.

In addition, since the luminance of the image has a great influence on the energy consumption, the energy consumption of the display screen can be reduced by adjusting the luminance of the image in the embodiment of the present disclosure, specifically, adjusting luminance data in the frame data to the luminance threshold value. Wherein, the frame data represents data of the image to be displayed by the display screen, and luminance data in the frame data represents a luminance of the image.

For instance, the current luminance of the image is 500 cd/m², and the preset luminance threshold value is 450 cd/m². After comparison, if it is determined that the current luminance (500 cd/m²) of the image is larger than the preset luminance threshold value (450 cd/m²), the luminance of the image is adjusted to the luminance threshold value, i.e., adjusting the luminance of the image to 450 cd/m². Since the luminance threshold value is a luminance value set in accordance with the energy efficiency standard, the energy efficiency of the television can be enabled to meet the energy efficiency standard by adjusting the luminance data to a size of the luminance threshold value.

In the embodiment of the present disclosure, the luminance threshold value is used as a standard to adjust the luminance of the image, so as to improve the accuracy of the energy efficiency control for the television.

In another embodiment of the present disclosure, as shown in FIG. 6, step S402 of the embodiment shown in FIG. 4 may include the following step:

- In step S4022, luminance data in the frame data is adjusted to 70%-80% of current luminance data.

The embodiment of the present disclosure is basically similar with the above embodiments, which also reduces the energy consumption of the television by reducing the luminance of the image. The difference is that if it is determined that the luminance data is larger than the preset luminance threshold value in the embodiment of the present disclosure, the luminance of the image displayed by the display screen is directly adjusted to 70%-80% of current luminance, specifically, adjusting luminance data in the frame data to 70%-80% of the current luminance data. Wherein, the adjustment ratio of the luminance data can be arbitrary data among 70%-80%, which is not limited in the present disclosure.

For instance, the current luminance of the image is 500 cd/m², the preset luminance threshold value is 450 cd/m², and the adjustment ratio of the luminance data is 80%. After comparison, if it is determined that the current luminance (500 cd/m²) of the image is larger than the preset luminance threshold value (450 cd/m²), the luminance of the image is adjusted to 80% of the current luminance, i.e., adjusting the luminance of the image to 400 cd/m². Since the adjusted image luminance is lower than the luminance threshold value, the energy efficiency control for the television can be realized by adjusting the luminance of the image to make the television meet the energy efficiency standard.

That is to say, in the embodiment of the present disclosure, the data processing amount of the television is reduced by equal-proportionally reducing directly according to the current luminance of the image, rather than taking the luminance threshold value as a standard to adjust the luminance of the image any more, which is easily implemented.

In another embodiment of the present disclosure, as shown in FIG. 7, step S402 of the embodiment shown in FIG. 4 may include the following step:

- In step S4023, a backlight luminance of the television is adjusted to 70%-80% of current backlight luminance.

The display screen provides the backlight luminance by the backlight, and the backlight is always in a lightening state after the television is opened. Therefore, in the embodiment of the present disclosure, the energy consumption of the television can be reduced by adjusting the luminance of the backlight, thereby realizing the energy efficiency control for the television.

Wherein, one of ordinary skilled in the art can select an arbitrary numerical value among 70%-80% as an adjustment ratio of the backlight according to actual requirements, which is not limited in the present disclosure.

Since the backlight is merely a light-emitting device in the television, the energy efficiency control can be performed for the television by adjusting the luminance of the backlight, which is easily implemented.

In another embodiment of the present disclosure, as shown in FIG. 8, step S200 of the embodiment shown in FIG. 2 may include the following step:

- In step S201, frame data of two or more frames corresponding to the cache address is searched for, wherein the frame data of two or more frames is continuous frame data.

Since the frame data is a continuous data stream, frame data of two or more frames can be searched for according to the cache address, in order to determine types of the frame data in the subsequent step. Wherein, the number of the frame data may be an arbitrary numerical value of more than two frames, e.g. three frames, four frames, five frames, etc., which is not limited in the present disclosure.

In another embodiment of the present disclosure, as shown in FIG. 9, step S300 of the embodiment shown in FIG. 8 may include the following step:

- In step S311, whether the frame data is a dynamic frame is determined.

In a normal case, the screens played in the television include a dynamic screen (such as television play or movie) and a static screen (such as static pictures), wherein the data frame corresponding to the dynamic screen is a dynamic frame, and the data frame corresponding to the static screen is a static frame.

Since the television has a higher energy consumption while playing the dynamic screen, and has a lower energy consumption while playing the static screen, it merely needs to perform energy efficiency control for the television when the television plays the dynamic screen. In the embodiment of the present disclosure, it is first determined whether the frame data is the dynamic frame after the frame data corresponding to the cache address is searched for. If it is determined that the frame data is the dynamic frame, the procedure advances to step S312, otherwise, the procedure ends.

In step S312, luminance data in the frame data is extracted as energy consumption parameter information.

In the embodiment of the present disclosure, luminance data in the frame data is extracted as the energy consumption parameter information if the frame data is the dynamic frame. That is to say, the luminance data in the frame data can be extracted only if the frame data is the dynamic frame, so as to perform energy efficiency control for the television in the subsequent step. If the frame data is the static frame, it does not need to perform energy efficiency control for the television, and thus it is unnecessary to extract the luminance data in the frame data.

In the embodiment of the present disclosure, the type of the frame data is used as an energy efficiency control condition of the television, thereby using different energy efficiency control strategies for different frame data and thus improving the energy efficiency control accuracy of the television.

In another embodiment of the present disclosure, as shown in FIG. 10, step S311 of the embodiment shown in FIG. 9 may include the following step:

- In step S3111, the frame data of two or more frames is compared two by two.

In the embodiment of the present disclosure, the frame data of each frame represents one image, and comparing the frame data two by two means to comparison of the images represented by respective frames two by two.

For example, if the frame data has two frames (i.e., first frame data and second frame data), the first frame data is compared with the second frame data. As another example, if the frame data has three frames (i.e., first frame data, second frame data and third frame data), the first frame data is compared with the second frame data, the first frame data is compared with the third frame data and the second frame data is compared with the third frame data.

In step S3112, whether there is difference among the frame data with two frames is determined.

If the frame data with two frames are identical, it is represented that two images are identical, i.e., the images played in the television are static images. If the frame data with two frames are different, it is represented that two images are different, i.e., the images played in the television are dynamic images. Thus, the type of the frame data can be determined according to a result of comparison among different frames.

In the embodiment of the present disclosure, if there is difference among the frame data with two arbitrary frames, the procedure advances to step S3113, otherwise, the procedure ends.

For instance, if the frame data includes three frames (i.e., first frame data, second frame data and third frame data), it is determined that the frame data is the dynamic frame if the frame data with two arbitrary frames therein are different, and the procedure advances to step S3113.

In step S3113, the frame data is determined as the dynamic frame.

If there is difference among the frame data with two frames, it is indicated that two images played in the television are different, such that the images played in the television are dynamic images, and the frame data corresponding to the dynamic image is the dynamic frame.

In the embodiment of the present disclosure, the type of the frame data is determined by comparing the frame data with two arbitrary frames, and the determination result is accurate and reliable.

It should be pointed out that, taking a buffer as an example in the embodiment of the present disclosure, the cache position of the frame data is exemplarily explained, which should not be used as limitation for the protection scope of the present disclosure. One of ordinary skilled in the art can use other storage devices to cache the frame data according to actual requirements, which should fall into the protection scope of the present disclosure.

The cache address is transmitted to a display adaptation layer after the application layer receives the cache address of the frame data, and the display adaptation layer searches for frame data corresponding to the cache address in the buffer according to the cache address, thereby displaying a corresponding image on a display screen according to the frame data.

A frame data searching module 11200 is configured to search for frame data corresponding to the cache address.

Since the frame data has a one-to-one mapping relationship with the cache address, the frame data can be uniquely determined after the cache address is determined. At this time, since the cache address of the frame data has been acquired in the application layer, the corresponding frame data can be searched for according to the cache address.
