Description

Technical Field

[0001] The present invention relates to the technical field of display screens, and particularly relates to a method and system for adjusting the picture of a liquid crystal display screen. Background Art

[0002] Currently, most liquid crystal display screens are placed in the user's usage environment at a fixed position and in a fixed posture, resulting in a fixed display angle for the display picture of the liquid crystal display screen. Thus, when a user views the liquid crystal display screen, the user needs to adjust the viewing posture according to the display angle of the display picture of the liquid crystal display screen. However, the adjusted viewing posture of the user may not be the most comfortable posture, resulting in a poor user experience. Secondly, even if the user adjusts the viewing posture to the most comfortable posture, the process of adjusting the viewing posture may delay the progress of viewing the display picture in the liquid crystal display screen, etc., which will also lead to a poor user experience.

[0003] Therefore, there is an urgent need for a solution. Summary of the Invention

[0073] Other features and advantages of the present invention will be set forth in the following description, and in part will be obvious from the description, or may be learned by practice of the present invention. The objectives and other advantages of the present invention may be realized and attained by the structure particularly pointed out in the written description, claims, as well as the drawings.

[0074] The technical solution of the present invention will be further described in detail below with reference to the drawings and embodiments. Description of the Drawings

[0075] The drawings are used to provide a further understanding of the present invention, and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention, but do not constitute a limitation to the present invention. In the drawings:

[0076] Figure 1 It is a schematic diagram of a method for adjusting the screen of a liquid crystal display in an embodiment of the present invention;

[0077] Figure 2 It is a schematic diagram of a system for adjusting the screen of a liquid crystal display in an embodiment of the present invention. Detailed Embodiments

[0078] The following describes the preferred embodiments of the present invention with reference to the drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0079] An embodiment of the present invention provides a method for adjusting the screen of a liquid crystal display, as Figure 1 shown, including:

[0080] S1. When the user is viewing the liquid crystal display, obtain multiple viewing postures of the user that exceed the duration threshold within the first time period;

[0081] S2. Based on each viewing posture, adjust multiple display screens displayed by the liquid crystal display within the second time period;

[0082] Wherein, the second time period starts after the first time period, and the second time period is adjacent to the first time period.

[0083] The first time period can be the last 5 minutes; the second time period is the next 10 minutes; the duration threshold can be 30 seconds; the viewing posture refers to the body posture of the user viewing the liquid crystal display; based on each viewing posture, adjust multiple display screens displayed by the liquid crystal display within the second time period until the display screen is suitable for the user to continue viewing the liquid crystal display in the viewing posture. For example: if the viewing posture is that the user is sitting obliquely to view, then in the liquid crystal display, a virtual display screen is created, and the virtual display screen is controlled to display the display screen and is controlled to face the user sitting obliquely.

[0084] The display screen of the present application can adaptively adjust according to the user's viewing posture. The user does not need to adjust the viewing posture according to the display angle of the display screen of the liquid crystal display, and can directly make the most comfortable posture to view the liquid crystal display, improving the user experience and not delaying the progress of the user viewing the display screen in the liquid crystal display.

[0085] In one embodiment, the adjustment of multiple display screens displayed by the liquid crystal display in the second time period based on each viewing posture includes:

[0086] Sort each display screen according to the display sequence to obtain a picture sequence;

[0087] Determine multiple local sequences that meet the local sequence conditions from the picture sequence;

[0088] Traverse each local sequence in turn. Each time it is traversed, determine the picture adjustment strategy of the traversed local sequence, and based on the picture adjustment strategy, adjust multiple display screens in the traversed local sequence;

[0089] Among them, the local sequence conditions include:

[0090] The local sequence contains at least two display screens; and,

[0091] The first and last of the local sequence are the first target pictures; and,

[0092] The ratio of the number of the first target pictures to the number of the second target pictures in the local sequence is greater than or equal to the ratio threshold;

[0093] Among them, the first target picture is a display screen that meets at least one adjustment object range of each viewing posture; the second target picture is a display screen other than the first target picture.

[0094] The display order is the order in which the liquid crystal display sequentially displays each display screen in the second time period; the local sequence meets the local sequence conditions, indicating that all the display screens in the local sequence need to be adjusted simultaneously; the screen adjustment strategy is a strategy for simultaneously adjusting all the display screens in the local sequence; based on the screen adjustment strategy, multiple display screens in the traversed local sequence are adjusted; in the local sequence conditions, the adjustment object range of the viewing posture refers to the range of the screen content that needs to be adjusted when the user makes this adjustment posture. For example, if the viewing posture is the posture of following the teacher to do yoga, the adjustment object range is the demonstration posture content of the teaching teacher in the display screen; restricting the local sequence to only contain two display screens can enable the simultaneous adjustment of multiple display screens, improve the rationality of the use of adjustment resources, and improve the adjustment efficiency; secondly, restricting that the first and last of the local sequence are the first target screens means that the display screens at the first and last fall within the adjustment object range. However, the display screens that are not at the first and last can be either the first target screen or the second target screen. If they are the second target screen, since they are adjacent to the first target screen in the local sequence and will be played continuously together, they also need to be adjusted. In this way, the rationality and applicability of the adjustment can be improved; finally, restricting that the ratio of the number of the first target screens to the number of the second target screens in the local sequence is greater than or equal to the ratio threshold, and the ratio threshold can be 1 / 3. This can ensure that there are as many first target screens as possible in the local sequence, making it more necessary to simultaneously adjust all the display screens in the local sequence and improving the rationality of the division of the local sequence.

[0095] In one embodiment, the screen adjustment strategy for the traversed local sequence includes:

[0096] Extract features from the traversed local sequence to obtain multiple first feature values;

[0097] Based on each first feature value, construct a first feature representation vector;

[0098] Determine multiple applicable strategy conditions corresponding to the first feature representation vector from the applicable strategy condition library;

[0099] Determine the target candidate adjustment strategy that meets all the applicable strategy conditions from the multiple candidate adjustment strategies for each viewing posture;

[0100] Determine the relevant strategy items that each display screen in the traversed local sequence has in the target candidate adjustment strategy;

[0101] When the display screen in the traversed local sequence has only one relevant strategy item, use the corresponding relevant strategy item as the direct strategy and associate it with the corresponding display screen;

[0102] When there are more than two relevant policy items in the same display screen of the traversed local sequence, perform policy fusion on the relevant policy items of the corresponding display screen to obtain a fusion policy and associate it with the corresponding display screen;

[0103] When the display screen in the traversed local sequence does not have relevant policy items, determine a supplementary policy based on the relevant policy items of the previous and next preset number of display screens of the corresponding display screen in the traversed local sequence, and associate it with the corresponding display screen;

[0104] Integrate the direct policy, fusion policy, and supplementary policy associated with each display screen in the traversed local sequence to obtain a screen adjustment policy.

[0105] The first eigenvalue includes: the content type of each display screen in the local sequence, the total number of display screens in the local sequence, etc.; based on each first eigenvalue, a first feature representation vector is constructed in vector form; in the applicable policy condition library, there are applicable policy conditions corresponding to different first feature representation vectors, and the applicable policy condition is a condition representing that the to-be-selected adjustment policy is applicable to adjusting the display screens in the traversed local sequence. For example, if the first eigenvalue that makes up the first feature representation vector is that the content type of the display screen in the local sequence is a yoga teaching demonstration action, then the corresponding applicable policy condition is that the to-be-selected adjustment policy needs to be an adjustment to the yoga teaching demonstration action; the multiple to-be-selected adjustment policies for the viewing posture are preset policies that can adjust the display screen according to the viewing posture; when the to-be-selected adjustment policy meets all the applicable policy conditions, it means that it can be used to adjust the display screens in the traversed local sequence, and it is used as the target to-be-selected adjustment policy; the relevant policy item refers to the sub-policy in the target to-be-selected adjustment policy that adjusts a single display screen; when the display screen has only one relevant policy item, the corresponding relevant policy item can be directly used as the direct policy and associated with the corresponding display screen; when the same display screen has more than two relevant policy items, in order to avoid unreasonable situations such as contradictions and repetitions when the more than two relevant policies it has are executed, the relevant policy items of the corresponding display screen are fused to obtain a fused policy and associated with the corresponding display screen; when the display screen does not have a relevant policy item, based on the relevant policy items of the display screens before and after the corresponding display screen in the traversed local sequence with a preset number, a supplementary policy is determined and associated with the corresponding display screen; the preset number can be 2; the direct policy, fused policy, and supplementary policy associated with each display screen in the traversed local sequence are integrated to obtain a screen adjustment policy. When determining the screen adjustment policy for the traversed local sequence in the embodiment of the present invention, applicable policy conditions are introduced, the target to-be-selected adjustment policy is determined based on the applicable policy conditions, and according to the different situations of the relevant policy items of the display screens in the traversed local sequence, the direct policy, fused policy, and supplementary policy are respectively determined, and finally integrated to obtain the screen adjustment policy, which improves the rationality, accuracy, and comprehensiveness of the determination of the screen adjustment policy, and greatly improves the applicability of the system.

[0106] In one embodiment, the fusing the relevant policy items of the corresponding display screen to obtain a fused policy includes:

[0107] Performing feature extraction on the relevant policy items of the corresponding display screen to obtain a plurality of second eigenvalues;

[0108] Based on each second eigenvalue, constructing a second feature representation vector;

[0109] Determine multiple policy fusion rules corresponding to the second feature representation vector from the policy fusion rule library;

[0110] Based on each policy fusion rule, perform policy fusion on the relevant policy items of the corresponding display screen to obtain a fusion policy.

[0111] The second feature values include: the policy types, adjustment objects, etc. of the relevant policy items of the display screen; based on each second feature value, construct a second feature representation vector in vector form; there are policy fusion rules corresponding to different second feature representation vectors in the policy fusion rule library, and the policy fusion rule is a rule for performing policy fusion on relevant policy items. For example: if the second feature values that make up the second feature representation vector are that the policy type of the relevant policy item of the display screen is to adjust the display screen color and to adjust the demonstration angle of the yoga teaching demonstration action in the display screen, then the two do not conflict when executed, and the corresponding policy fusion rule is to combine the relevant policy items of the display screen and execute them together; based on each policy fusion rule, perform policy fusion on the relevant policy items of the corresponding display screen to obtain a fusion policy.

[0112] In one embodiment, the determining of the supplementary policy based on the relevant policy items of the previous and next preset number of display screens in the traversed partial sequence corresponding to the display screen includes:

[0113] Determine target policy items with the policy type of the standard policy type from the relevant policy items of the previous and next preset number of display screens in the traversed partial sequence corresponding to the display screen;

[0114] Extract features from the target policy items and the sequence position relationship between the display screen with the target policy items and the corresponding display screen in the traversed partial sequence to obtain multiple third feature values;

[0115] Based on each third feature value, construct a third feature representation vector;

[0116] Determine a supplementary policy formulation rule corresponding to the third feature representation vector from the supplementary policy formulation rule library;

[0117] Formulate a supplementary policy based on the supplementary policy formulation rule.

[0118] When the policy type of the relevant policy item is the standard policy type, it means that the display screens without the relevant policy item need to be adjusted in coordination. For example, if the standard policy type is screen brightness adjustment, then if the brightness of a display screen is adjusted alone without adjusting the brightness of the adjacent display screen, the user may feel uncoordinated when watching. Therefore, it means that the display screens without the relevant policy item need to be adjusted in coordination. The third eigenvalue includes: the adjustment type of the target policy item, the adjustment object, the number of interval display screens between the display screen with the target policy item and the display screen without the relevant policy item, etc. Based on each third eigenvalue, a third feature representation vector is constructed in the form of a vector. There are supplementary policy formulation rules corresponding to different third feature representation vectors in the supplementary policy formulation rule library. The supplementary policy formulation rules are execution rules for formulating supplementary policies for screen adjustment for display screens without the relevant policy items. For example, if the third eigenvalue constructed into the third feature representation vector is the adjustment type of the target policy item to increase the screen brightness by 10%, then the corresponding supplementary policy formulation rule is to increase the screen brightness of the display screen without the relevant policy item by 10%.

[0119] The embodiment of the present invention provides a picture adjustment system for a liquid crystal display screen, such as Figure 2 As shown, including:

[0120] An acquisition module 1 is used to acquire, when a user views a liquid crystal display screen, a plurality of viewing postures maintained by the user for a period exceeding a threshold within a first time period;

[0129] The first and last frames of the local sequence are the first target frames; and,

[0131] Wherein, the first target frame is a display screen that conforms to at least one adjusted object range for each viewing posture; the second target frame is a display screen other than the first target frame.

[0139] When the same display screen in the traversed local sequence has more than two relevant strategy items, fuse the relevant strategy items that the corresponding display screen has to obtain a fused strategy and associate it with the corresponding display screen;

[0140] When the display screen in the traversed local sequence has no relevant strategy item, determine a supplementary strategy based on the relevant strategy items that the corresponding display screen has in the previous and next preset number of display screens in the traversed local sequence and associate it with the corresponding display screen;

[0141] Integrate the direct strategy, the fused strategy, and the supplementary strategy associated with each display screen in the traversed local sequence to obtain a frame adjustment strategy.
