[0002] Virtual pixel technology uses algorithms to control the light source in the screen, allowing it to participate in the imaging of multiple adjacent pixels, achieving higher display resolution. Virtual pixels create a proportional relationship between the number of physical pixels on the screen and the number of pixels actually displayed, allowing the display to display a greater number of image pixels than the actual physical number.

[0003] Virtual pixel technology has the advantages of improving screen display performance and reducing costs, and also improves the user's viewing experience to a certain extent.

[0004] However, in practice, due to factors such as technology and light source characteristics, screens using virtual technology may have color differences when displaying the same color, and cannot accurately display images, affecting the user experience. Summary of the Invention

[0040] Various exemplary embodiments, features, and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0041] In the description of the present disclosure, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present disclosure.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the present disclosure, "plurality" means two or more, unless otherwise specifically defined.

[0043] In this disclosure, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on specific circumstances.

[0044] The term "and / or" herein simply describes an association relationship between associated objects, indicating that three relationships can exist. For example, "A and / or B" can represent the existence of three situations: A alone, A and B simultaneously, and B alone. Furthermore, the term "at least one" herein refers to any combination of at least two of any one or more of a plurality of items. For example, "at least one of A, B, and C" can represent any one or more elements selected from the set consisting of A, B, and C.

[0045] On a screen using virtual technology, a single pixel corresponds to a single light-emitting component. A single component can include two light sources: a primary light source and an auxiliary light source. For example, a single light-emitting component can include three primary light sources and one auxiliary light source. The color emitted by the auxiliary light source can be displayed in two ways: directly using the auxiliary light source for display, or by mixing the light emitted by the primary light sources.

[0046] Due to factors such as manufacturing process, luminous efficiency, and the luminescent properties of inorganic luminescent materials, the actual brightness of the light source (primary color light source and auxiliary light source) may not match the theoretical brightness. Consequently, the colors displayed by these two methods are not exactly the same. This results in different display effects for the same color across the entire screen, making it difficult to accurately display images and affecting the user experience.

[0047] Figure 1 Schematic diagram of the process of eliminating screen color difference provided by the embodiment of the present disclosure. Figure 1 As shown, the method is applied to a screen, wherein the screen includes multiple primary color light sources and at least one auxiliary light source. The method includes:

[0048] S11 , obtaining the display brightness of the color to be displayed and the expected auxiliary brightness of the auxiliary light source.

[0049] The color to be displayed can be the color that needs to be displayed by the pixel in the screen. The pixel here refers to the screen pixel. The light-emitting component corresponding to the pixel emits light to obtain the color to be displayed. The display brightness of the color to be displayed can be the brightness of the light emitted by the light-emitting component. A single color can be mixed from three primary colors, so the display brightness can include three primary color components. For ease of description, the brightness of the primary color component is named the first brightness. For example: the display brightness can be expressed as: (140, 160, 20), and the single number in the bracket represents the first brightness of a primary color component. The brightness to be displayed can be calculated according to an algorithm, or it can be determined according to the color of the image pixel in the image to be displayed.

[0050] The expected auxiliary brightness may be the brightness that the auxiliary light source should emit, and may be specified according to an algorithm or determined according to the color of image pixels in the image to be displayed.

[0051] S12 : Obtain a first mixing ratio of the primary color lights emitted by the at least two primary color light sources, when the at least two primary color light sources as a whole emit the same visible light as the at least one auxiliary light source.

[0052] The same visible light here can be visible light with the same color and brightness. In the related art, the primary color lights emitted by at least two primary color light sources can be mixed in equal proportions to obtain the light emitted by the auxiliary light source. Equal proportion means that the brightness of the two primary color lights is the same, that is, they are mixed in equal brightness proportions. Moreover, the brightness of the light emitted by the auxiliary light source is the same as the brightness of the two primary color lights. However, due to factors such as the process, luminous efficiency, and the luminous properties of inorganic luminescent materials, the light obtained by mixing at least two primary color lights in equal proportions cannot be the same as the light emitted by the auxiliary light source. Therefore, it is necessary to redefine the first mixing ratio.

[0053] The first mixing ratio can reduce the difference between the light obtained by mixing the primary lights and the light emitted by the auxiliary light source. This can be achieved by using a measuring device to measure the mixed light after the primary lights are mixed, comparing it with the light emitted by the auxiliary light source, and then adjusting the brightness of the primary light source. When the difference between the mixed light and the light emitted by the auxiliary light source is less than a brightness threshold, the brightness of each primary light source that is mixed to form the mixed light is recorded, thereby obtaining the first mixing ratio. The above is merely an example, and the presently disclosed embodiments do not limit the method for determining the first mixing ratio. Another method for determining the first mixing ratio will be described below.

[0054] In a possible implementation, the primary color light sources include: a red light source, a green light source, and a blue light source; and the auxiliary light source includes: a white light source, or a yellow light source, or a purple light source, or a cyan light source.

[0055] Mixing the light from red, green, and blue light sources in equal proportions produces white light. Mixing the light from green and red light sources in equal proportions produces yellow light. Mixing the light from green and blue light sources in equal proportions produces cyan light. Mixing the light from red and blue light sources in equal proportions produces violet light.

[0056] In the embodiments of the present disclosure, the primary color light source and the auxiliary light source can cover the vast majority of screens on the market, thereby improving the universality of the present disclosure.

[0057] S13 , determining the primary color brightness of each of the primary color light sources based on the display brightness, the expected auxiliary brightness, and the first mixing ratio, to generate a virtual pixel.

[0058] In the disclosed embodiment, the first mixing ratio is determined by the process of mixing the primary color light with the light emitted by the auxiliary light source. In fact, the first mixing ratio can indirectly represent the difference between the actual brightness of the light source and the theoretical brightness during this process. Subsequently, the first mixing ratio can be used to reduce this difference to obtain the primary color brightness.

[0059] For example, a first mixing ratio can be used to eliminate the difference between the actual brightness of the auxiliary light source and the theoretical brightness to obtain the actual brightness of the auxiliary light source. The actual brightness of the auxiliary light source is then subtracted from the displayed brightness to obtain the primary color brightness of each primary light source. Furthermore, the primary color brightness and the actual brightness of the auxiliary light source can be used to generate virtual pixels.

[0060] In the embodiment of the present disclosure, the primary color light sources are no longer mixed in equal proportions, but a first mixing ratio of the primary color light sources is determined. The first mixing ratio can reduce the difference in display colors of the two display modes (the color displayed by the mixed primary color light sources and the color displayed by the auxiliary light source alone). The display brightness, the expected auxiliary brightness and the first mixing ratio are then used together to determine the brightness of each primary color to generate a virtual pixel. Therefore, the method of the present disclosure can eliminate the uneven color display of the screen caused by factors such as process, luminous efficiency, and luminous characteristics of inorganic luminescent materials, thereby improving the uniformity and accuracy of the screen display and enhancing the user experience.

[0061] In one possible implementation, the primary lights are mixed to obtain the auxiliary light actually emitted by the auxiliary light source, and a plurality of lights of specified wavelengths are mixed to obtain the primary lights and the auxiliary light. The obtaining of a first mixing ratio of the primary lights emitted by the at least two primary light sources, when at least two primary light sources as a whole emit the same visible light as the at least one auxiliary light source, includes: determining a first response intensity of cone cells to the multiple lights of specified wavelengths in the auxiliary light; determining a second response intensity of cone cells to the multiple lights of specified wavelengths in each primary light mixed to obtain the auxiliary light; and determining each first mixing ratio based on each of the first response intensities and each of the second response intensities.

[0062] The three primary colors of light can be red, green, and blue. Theoretically, at least two primary colors can be mixed in equal proportions to produce auxiliary light. The disclosed embodiments do not limit the use of multiple designated wavelengths of light. Multiple designated wavelengths of light can be mixed in different proportions to produce light of different colors. These multiple designated wavelengths of light can at least produce the primary colors and auxiliary light.

[0063] The intensity of a cone's response to a single color can be the intensity of the cone's response to each of the specified wavelengths that make up that single color. This intensity of response can quantify the human eye's perception of color.

[0064] In one possible implementation, the multiple specified wavelengths of light are wavelengths corresponding to three imaginary primary colors in the Commission Internationale de l'Eclairage (CIE) XYZ colorimetry system. For example, the multiple specified wavelengths may be: 700 nanometers, 546.1 nanometers, and 435.8 nanometers. The response intensities of cone cells to the specified wavelengths may be tristimulus values. Tristimulus values ​​can be obtained by lookup in a table; that is, the response intensities can be obtained by lookup in the table.

[0065] For ease of distinction, the cone cell response intensity to each designated wavelength of light constituting the auxiliary light is designated as the first response intensity. A single designated wavelength can correspond to at least one first response intensity. The cone cell response intensity to each designated wavelength of primary light is designated as the second response intensity. If there are n primary light sources, a single designated wavelength can correspond to n second response intensities, where n is a positive integer.

[0066] The first response intensity may represent the perception of the human eye to the auxiliary light emitted by the auxiliary light source, and the second response intensity may represent the perception of the human eye to the mixed light obtained by mixing the primary color lights.

[0067] Illustratively, the first response intensity may be directly measured using a colorimeter. For example, a colorimeter CA410 may be used to measure the auxiliary light emitted by the auxiliary light source.

[0068] For example, the brightness of each primary color component of the auxiliary light emitted by the auxiliary light source can be derived based on the first response intensity. Then, based on the brightness of each primary color component, the brightness of the light of the specified wavelengths of the three primary colors can be inferred, thereby obtaining the second response intensity corresponding to each specified wavelength.

[0069] For users, visual perception is the key to determining whether the screen display is uniform. Therefore, in the disclosed embodiment, the first mixing ratio is determined based on the first response intensity and the second response intensity. This makes the colors displayed on the screen more visually uniform, improving the user experience.

[0070] In one possible implementation, determining each first mixing ratio based on each first response intensity and each second response intensity includes: establishing a first mixing ratio model with the first response intensity and the second response intensity corresponding to a single specified wavelength of light as dependent variables and each first mixing ratio as an independent variable; and obtaining the first mixing ratio based on each first mixing ratio model.

[0071] For a single specified wavelength of light, a first mixing ratio model is established with the goal of achieving a sum of a first response intensity corresponding to the specified wavelength of light and a second response loudness corresponding to the specified wavelength of light being equal (ie, with a goal of response intensity balance).

[0072] Assuming that the auxiliary light emitted by the auxiliary light source can be obtained by mixing various primary color lights according to a first mixing ratio, then the balance between the second response intensity and the first response intensity must also be achieved under the first mixing ratio.

[0073] For ease of understanding, the first mixing ratio model established for each specified wavelength light is expressed using formula (1). For example, there are three specified wavelength lights, namely, the first specified wavelength light, the second specified wavelength light, and the third specified wavelength light; the primary color lights include: the first primary color light, the second primary color light, and the third primary color light.

[0074]

[0075] Among them, X W Characterizes the first response intensity corresponding to the first specified wavelength light constituting the auxiliary light, X r Characterizes the second response intensity corresponding to the first specified wavelength light constituting the first primary color light, X g Characterizes the second response intensity corresponding to the first specified wavelength light constituting the second primary color light; Z b Characterizes the second response intensity corresponding to the first specified wavelength light constituting the third primary color light; Y W Characterizes the first response intensity corresponding to the second specified wavelength light constituting the auxiliary light, Y r Characterizes the second response intensity corresponding to the second specified wavelength light constituting the first primary color light, Y g Characterizes the second response intensity corresponding to the second specified wavelength light constituting the second primary color light; Y b Characterizes the second response intensity corresponding to the second specified wavelength light constituting the third primary color light; Z W Characterizes the first response intensity corresponding to the third specified wavelength light constituting the auxiliary light, Z r Characterizes the second response intensity corresponding to the third specified wavelength light constituting the first primary color light, Z g Characterizes the second response intensity corresponding to the third specified wavelength light constituting the second primary color light; Z b Characterizes the second response intensity corresponding to the third specified wavelength light constituting the third primary color light; a represents the first mixing ratio corresponding to the first primary color light, g represents the first mixing ratio corresponding to the second primary color light, and b represents the first mixing ratio corresponding to the third primary color light.

[0076] In the disclosed embodiment, a first mixing ratio model corresponding to each designated wavelength is established with the goal of balancing response intensity. The first mixing ratio corresponding to each primary color in the first mixing ratio model serves as the model's independent variable. By combining these first mixing ratio models, each first mixing ratio can be determined. This ensures that each first mixing ratio is determined with the goal of enhancing visual quality, resulting in visually enhanced display uniformity and accuracy.

[0077] In one possible implementation, the display brightness includes the first brightness of each primary color component of the color to be displayed, and determining the primary color brightness of each primary color light source based on the display brightness, the expected auxiliary brightness, and the first mixing ratio includes: determining the second brightness of each primary color component of the auxiliary light based on the expected auxiliary brightness and each first mixing ratio; and determining each primary color brightness based on each second brightness and the first brightness corresponding to each second brightness.

[0078] The expected auxiliary brightness can also be represented by each primary color component, and the representation form will not be repeated here. For ease of description, the brightness of each primary color component in the expected auxiliary brightness can be named as the second brightness. For a single primary color component, the weighted second brightness obtained by weighting the first mixing ratio corresponding to the primary color component can be removed from the first brightness to obtain the primary color brightness of the primary color component. For ease of understanding, the brightness of each primary color is expressed using formula (2). For example: the primary color light includes: the first primary color light, the second primary color light, and the third primary color light.

[0079]

[0080] Among them, R ′ Indicates the primary color brightness of the first primary color light, G ′ Indicates the primary color brightness of the second primary color light, B ′ R represents the first brightness of the first primary color light, G represents the first brightness of the second primary color light, and B represents the first brightness of the third primary color light.

[0081] In the embodiment of the present disclosure, the first mixing ratio can be used to reduce the difference between the actual brightness and theoretical brightness of each light source (primary color light source, auxiliary light source), thereby improving the accuracy of the brightness of each primary color and making the generated virtual pixel color more uniform.

[0085] The primary color brightness unit 23 is configured to determine the primary color brightness of each of the primary color light sources based on the display brightness, the expected auxiliary brightness, and the first mixing ratio, so as to generate a virtual pixel.

[0086] In a possible implementation, the primary color lights are mixed to obtain the auxiliary light actually emitted by the auxiliary light source, and a plurality of lights of specified wavelengths are mixed to obtain the primary color lights and the auxiliary light. The first mixing ratio acquisition unit 22 is further configured to:

[0087] determining a first response intensity of cone cells to the plurality of specified wavelengths of light in the auxiliary light;

[0088] determining a second response intensity of the cone cells to the multiple specified wavelengths of light in each primary color light mixed to form the auxiliary light;

[0089] The first mixing ratios are determined based on the first response intensities and the second response intensities.

[0090] In a possible implementation, determining each first mixing ratio based on each first response intensity and each second response intensity includes:

[0091] Establishing a first mixing ratio model with the first response intensity and the second response intensity corresponding to the single light of the specified wavelength as dependent variables and the first mixing ratios as independent variables;

[0092] The first mixing ratio is obtained based on each of the first mixing ratio models.
