However, it will be apparent to those skilled in the art that the present application can be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0021] In order to illustrate the technical solutions described in the present application, the following will be described by specific embodiments.

[0022] Figure 1 A display screen control method based on artificial intelligence provided by the embodiment of the application is shown, and the display screen control method based on artificial intelligence comprises:

[0023] S1: receiving a video to be displayed;

[0024] S2: for each pixel, determining a frame color corresponding to each frame in the video;

[0025] S3: for each two adjacent frame colors of the pixel, taking the former frame color as a first frame color and the latter frame color as a second frame color;

[0026] S4: determining a color value change of each color component of the pixel in the process of the pixel from the first frame color to the second frame color, thereby determining a process molecular angle and a rotation angle of a liquid crystal molecule corresponding to the color value component;

[0027] S5: determining a target rotation speed of the corresponding liquid crystal molecule according to the determined process molecular angle and rotation angle, wherein making each liquid crystal molecule rotate at the determined target rotation speed can minimize the color change degree of the pixel in the process of the pixel from the first frame color to the second frame color;

[0028] S6: when playing the video, for each pixel, when the current frame color of the pixel is converted into the next frame color each time, controlling the corresponding liquid crystal molecule to rotate according to the determined target rotation speed.

[0029] In the embodiment, the method is executed in a terminal device with an LCD display screen, such as a television, a desktop computer, a tablet computer, a notebook computer, a mobile phone, etc.

[0030] In the embodiment, the video to be displayed can be a video stored in the terminal device itself or a video transmitted to the terminal device by another device.

[0031] In the embodiment, the pixel is a pixel of the LCD display screen, and each pixel corresponds to three color value components of red, green and blue. In the display screen, a corresponding liquid crystal molecule is provided for each color value component. When a driving voltage is applied to the terminal device, the liquid crystal molecule rotates to a different molecular angle (the initial molecular angle can be regarded as 0, and the other molecular angle is obtained by adding the rotation angle to 0), and the light transmittance of the corresponding light changes, thereby changing the color value of the corresponding color value component and changing the color of the pixel.

[0032] In the embodiment, the current color is the first frame color and the next frame color is the second frame color when the color of the current frame of the pixel is converted to the color of the next frame.

[0033] In the embodiment, the rotation angle is the angle by which the liquid crystal molecule rotates from one molecular angle to another molecular angle, and the process molecular angle is the other molecular angle presented by the liquid crystal molecule in the process of rotation. Each color corresponds to specific color values of three color components, and the specific color values of the three color components correspond to specific molecular angles of three liquid crystal molecules. Therefore, in order to convert the pixel from one color to another color, the three groups of liquid crystal molecules need to be driven to rotate from one specific molecular angle to another specific molecular angle. However, in the process of rotation of the liquid crystal molecule, the liquid crystal molecule also presents other molecular angles (i.e. process molecular angles), which makes the corresponding color components present other colors, and the color formed by the color components may change suddenly compared with the previous color, thereby affecting the user's viewing experience.

[0034] In the present application, when playing a video, for each pixel, the liquid crystal molecules corresponding to each color component are cooperatively adjusted in the process of converting the current frame color to the next frame color, so that the degree of process color change due to the rotation of the liquid crystal molecules is minimized, thereby reducing the color mutation of the pixel as much as possible and ensuring the user's viewing experience.

[0035] As a preferred embodiment, determining the color value change of each color component of the pixel in the process of converting the pixel from the first frame color to the second frame color, thereby determining the process molecular angle and the rotation angle of the liquid crystal molecule corresponding to the color value component include:

[0036] For each color component of the pixel, a first color value corresponding to a first frame color and a second color value corresponding to a second frame color of the color component are identified, and a first molecular angle corresponding to a molecular angle of a liquid crystal molecule of the first color value and a second molecular angle corresponding to a molecular angle of a liquid crystal molecule of the second color value are determined;

[0037] Each molecular angle between the first molecular angle and the second molecular angle is identified as a process molecular angle, and an angle range from the first molecular angle to the second molecular angle is a process molecular angle range;

[0038] The rotation angle is calculated by the following formula:

[0039]

[0040] wherein, is the rotation angle, is the second molecular angle, is the first molecular angle.

[0041] In the embodiment, the color value of each color component is one of 0-255; the range of the molecular angle is 0-120 or other ranges, which is determined according to the type of the liquid crystal material of the display screen; so that each molecular angle corresponds to a specific color value, for example, the molecular angle is 100, and the corresponding color value is 213, and a mapping table of the color component and the molecular angle can be determined in advance and stored in the terminal device, so that the terminal device can be called at any time to determine that the molecular angle of the liquid crystal molecule corresponding to the first color value is the first molecular angle, and the molecular angle of the liquid crystal molecule corresponding to the second color value is the second molecular angle.

[0042] As a preferred embodiment, determining the target rotation speed of the corresponding liquid crystal molecule according to the determined process molecular angle and the rotation angle comprises:

[0043] S51: identifying the size of each process molecular angle range, and determining the division number according to the largest process molecular angle range;

[0044] S52: dividing each process molecular angle range into a plurality of sub-ranges according to the division number, and numbering each sub-range, wherein the number of sub-ranges in each process molecular angle range is consistent with the division number;

[0045] S53: grouping the sub-ranges with the same number in each process molecular angle range into a same sub-range set, wherein the number of the sub-range set is consistent with the number of the sub-ranges in the sub-range set;

[0046] S54: Select the first sub-range set as the base set, and determine a target molecular angle from each sub-range in the base set so that the color change between the process color obtained by fusing the target color value corresponding to the target molecular angle and the color of the first frame is minimized;

[0047] S55: Determine the rotation angle of the liquid crystal molecules corresponding to each color component of the pixel to convert them into the corresponding target molecule angle, and then determine the target sub-rotation speed of the liquid crystal molecules corresponding to each color component. The liquid crystal molecules rotate according to the corresponding target sub-rotation speed so that each color component can simultaneously reach the corresponding target color value.

[0048] S56: Select the next sub-range set as the base set, and determine a target molecular angle from each sub-range in the base set so that the color change between the process color obtained from the target color value corresponding to the target molecular angle and the previous process color is minimized. Execute steps S55 to S56 until the target sub-rotation speed corresponding to each color component of each sub-range set is determined.

[0049] S57: For each color component of the pixel, the set of all target sub-rotations of the determined color component is determined as the target rotation speed.

[0050] In this embodiment, a molecular angle range is defined for each color component (e.g., Figure 2 The molecular angle ranges are defined as: molecular angle range 1, molecular angle range 2, and molecular angle range 3. A maximum span for each sub-range is pre-defined, such as 2°. This means the span of each sub-range cannot exceed the maximum span. For example, the maximum molecular angle range could be 60°~70° (e.g., ...). Figure 3 As shown in the diagram, the total span is 10°. Dividing the total span by the maximum span of the sub-ranges, i.e., 10° / 2° = 5 divisions, allows for the division of the molecular angle range of 60°~70° into five sub-ranges: 60°~62°, 62°~64°, 64°~66°, 66°~68°, and 68°~70°. By setting the maximum span, each molecular angle range can be refined as much as possible. This allows for the subdivision of large-scale rotations of molecules from frame to frame into multiple micro-rotations (i.e., rotation from one target molecular angle to the next). Furthermore, by controlling the speed of each liquid crystal molecule's micro-rotation, the process color change caused by adjacent micro-rotations can be minimized. This makes the process color change of pixels during frame color conversion more continuous (the more sub-ranges there are, the more obvious this continuity becomes), thus ensuring a better viewing experience for the user.

[0051] As a preferred embodiment, determining one target molecular angle from each of the sub-ranges in the base set respectively, so that the color change degree between the process color obtained by the target color value corresponding to the target molecular angle and the last process color is minimum, includes:

[0052] determining all molecular angle combinations in the base set, wherein three molecular angles of each molecular angle combination are selected from three sub-ranges in the base set respectively; the three molecular angles of any two molecular angle combinations are not completely same;

[0053] for each molecular angle combination, calculating the color change degree between the color composed of the color values of the color components corresponding to the molecular angles in the molecular angle combination and the last process color;

[0054] determining the three molecular angles in the molecular angle combination with the minimum color change degree as the target molecular angles.

[0055] calculating the color change degree between the color composed of the color values of the color components corresponding to the molecular angles in the molecular angle combination and the last process color includes:

[0056] determining the Lab value of the color composed of the color values of the color components corresponding to the molecular angles in the molecular angle combination as a first Lab value;

[0057] determining the Lab value of the last process color as a second Lab value;

[0058] calculating the color change degree by the following formula:

[0059]

[0060] wherein D is the color change degree, L1 is the lightness of the first Lab value, L2 is the lightness of the second Lab value, a1 is the a channel value of the first Lab value, a2 is the a channel value of the second Lab value, b1 is the b channel value of the first Lab value, b2 is the b channel value of the second Lab value.

[0061] In the embodiment, in order to ensure that the number of process molecular angles is limited, the process molecular angles of each sub-range take integer multiples of 0.1°, such as 80.1°, 80.2°, but not 80.15°;

[0062] In the embodiment, the Lab value (i.e. Lab color space) is composed of 3 components; wherein L represents lightness, which generally ranges from 0 to 100, 0 represents black, and 100 represents white; the a component (i.e. a channel value) represents a range from dark green (greenish) to dark red (magenta), which generally ranges from -128 to 127 (slightly different in different implementations), a negative value represents a green direction, and a positive value represents a red direction; the b component (i.e. b channel value) represents a range from dark blue (blue-violet) to dark yellow (yellow), which also ranges from -128 to 127, a negative value represents a blue direction, and a positive value represents a yellow direction; it is designed based on the visual perception of the human eye; compared with other color spaces (such as RGB), the Lab color space has better perceptual uniformity; in simple terms, the coordinate distance of two colors in the Lab space can better reflect the degree of human eye perception of the difference between the two colors; for example, in the RGB space, the difference between two color values can be large, but the human eye hardly perceives the difference; but the difference in the Lab space can more accurately correspond to the actual visual perception of the human eye; therefore, the embodiment uses Lab color values to determine the degree of color change, which is more in line with the perception ability of the human eye and has higher accuracy.

[0063] As a preferred embodiment, determining the rotation angle of the liquid crystal molecule corresponding to each color component of the pixel to the corresponding target molecular angle, and then determining the target sub-rotation speed of the liquid crystal molecule corresponding to each color component includes:

[0064] For each color component corresponding to the liquid crystal molecule, identifying the molecular angle corresponding to the last process color of the liquid crystal molecule, identifying the angle difference between the molecular angle and the target molecular angle, and obtaining the rotation angle of the liquid crystal molecule corresponding to the corresponding target molecular angle;

[0065] Obtaining the fastest rotation speed of the liquid crystal molecule;

[0066] Identifying the largest rotation angle, and determining the fastest rotation speed as the target sub-rotation speed of the liquid crystal molecule corresponding to the rotation angle;

[0067] Dividing the largest rotation angle by the fastest rotation speed to obtain the rotation time;

[0068] For each other rotation angle corresponding to the liquid crystal molecule, dividing the rotation angle by the determined rotation time to obtain the target sub-rotation speed of the liquid crystal molecule corresponding to the rotation angle;

[0069] Binding the three determined target sub-rotation speeds with the rotation time.

[0070] The target sub-rotation speeds in the target sub-rotation speed set are sorted according to the determined time sequence; and the rotation of the liquid crystal molecules is controlled according to the determined target rotation speeds, that is, for the liquid crystal molecules of each color component, the rotation speed of the liquid crystal molecules is adjusted according to the sequence of the target sub-rotation speeds in the set, wherein when the liquid crystal molecules are adjusted to any target sub-rotation speed, the rotation time length of the liquid crystal molecules bound to the target sub-rotation speed is maintained.

[0071] In the embodiment, each target sub-rotation speed is the rotation speed of the corresponding liquid crystal molecules from the target molecular angle of the previous process color to the target molecular angle of the current process color (if the previous process color is the first frame color, the target molecular angle is the molecular angle corresponding to the first frame color); the terminal device has a maximum limit value for the driving voltage applied to the liquid crystal molecules, and therefore the liquid crystal molecules also have a maximum limit value for the rotation speed, that is, the fastest rotation speed (which can be preset in the terminal device after being detected); the rotation time length of the liquid crystal molecules from one molecular angle to another molecular angle mainly depends on the maximum rotation angle, in order to ensure the rotation efficiency of the molecules, the fastest rotation speed is determined as the target sub-rotation speed of the liquid crystal molecules corresponding to the maximum rotation angle, and the rotation time length is determined by the maximum rotation angle and the fastest rotation speed in the embodiment, since the rotation angles of other liquid crystal molecules are known, the target sub-rotation speeds of the other liquid crystal molecules can also be determined;

[0072] In addition, since after step S56, only the target sub-rotation speeds before the target molecular angle of the last sub-range are determined, and the target sub-rotation speed corresponding to the rotation angle between the target molecular angle and the molecular angle of the second frame color has not been determined, the target sub-rotation speed corresponding to the rotation angle can be obtained in the same manner as in the embodiment (taking the molecular angle corresponding to the second frame color as the current target molecular angle, and taking the target molecular angle of the last sub-range as the previous target molecular angle), and the target sub-rotation speed is also added to the target sub-rotation speed set to participate in speed adjustment; or since the rotation angle is too small, the visual impact caused by the rotation angle is not easy to be perceived, and each liquid crystal molecule can be directly adjusted from the last target molecular angle to the molecular angle corresponding to the second frame color at the fastest rotation speed.

[0073] In the embodiment, the target rotation speed is a variable rotation speed, and the variation manner is to change according to the sequence of the corresponding target sub-rotation speeds (the change of the driving voltage can control the change of the rotation speed of the liquid crystal molecules), and the rotation time length of the liquid crystal molecules at each target sub-rotation speed is the rotation time length bound to the target sub-rotation speed.

[0074] The terminal device provided in Embodiment Two of the present application comprises a memory and a processor, the memory stores a computer program, and the computer program is executed by the processor to make the processor execute the steps of the display screen control method based on artificial intelligence, specifically including:

[0079] S5: determining a target rotation speed of the corresponding liquid crystal molecule according to the determined process molecule angle and the rotation angle, wherein making each liquid crystal molecule rotate according to the determined target rotation speed can minimize a color change degree of the pixel in the process from the first frame color to the second frame color;

[0080] S6: when playing the video, for each pixel, when a current frame color of the pixel is converted into a next frame color each time, controlling the corresponding liquid crystal molecule to rotate according to the determined target rotation speed.

[0081] Embodiment three of the present application provides a storage medium, and the storage medium has a computer program stored thereon. When the computer program is executed by a processor, the processor executes the steps of the display screen control method based on artificial intelligence, and specifically includes the following steps:

[0082] S1: receiving a video to be displayed;

[0083] S2: determining, for each pixel, a frame color of the pixel corresponding to each frame in the video;

[0084] S3: for each two adjacent frame colors of the pixel, taking a former frame color as a first frame color and a latter frame color as a second frame color;

[0085] S4: determining a color value change of each color component of the pixel in a process of the pixel from the first frame color to the second frame color, so as to determine a process molecule angle and a rotation angle of a liquid crystal molecule corresponding to the color value component;

[0086] S5: determining a target rotation speed of the corresponding liquid crystal molecule according to the determined process molecule angle and the rotation angle, wherein making each liquid crystal molecule rotate according to the determined target rotation speed can minimize a color change degree of the pixel in the process from the first frame color to the second frame color;
