Description

Technical Field

[0001] This disclosure relates to the field of display technology, and in particular to a screen display method, apparatus, readable storage medium, and electronic device. Background Technology

[0002] Currently, high-end devices (such as smartphones and tablets) all use screens made of Organic Light-Emitting Diode (OLED) material. OLED screens have advantages such as high color gamut and high contrast. Because the color gamut of OLED screens exceeds the standard red-green-blue (sRGB) color gamut and the wide color gamut P3, system-level color gamut calibration is required before user use. This calibrates the non-standard OLED screen color gamut to the standard sRGB and P3 color gamut to achieve accurate color display. However, current color gamut calibration is performed in dark environments. Users typically use these devices in bright environments, such as indoors or outdoors. In these conditions, the screen usually has about 5% reflection. Therefore, the color entering the human eye is a combination of the screen's own emitted color and the color of reflected ambient light. This results in the color seen by the human eye not being the color used during calibration in dark environments, leading to inaccurate screen colors. Summary of the Invention

[0045] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0046] Figure 1 This is a flowchart illustrating a screen display method according to an exemplary embodiment, wherein the screen display method can be applied to terminals with screens such as smartphones and tablets. Figure 1 As shown, the screen display method may include the following steps S101 to S103.

[0047] In S101, the current ambient light illuminance and current ambient light color temperature of the screen are obtained.

[0048] In this disclosure, the current ambient light illuminance can be collected by an illuminance sensor installed on the terminal, and the current ambient light color temperature can be collected by a color temperature sensor installed on the terminal.

[0049] In S102, the target RGB value of each pixel in the image to be displayed is determined based on the current ambient light illuminance and the current ambient light color temperature.

[0050] In this disclosure, ambient light refers to the ambient light of the environment in which the terminal's screen is located, and ambient light includes, but is not limited to, artificial ambient light and natural ambient light. For example, artificial ambient light includes artificial light, and natural ambient light includes sunlight, moonlight, etc. The target RGB value is the RGB value of the image that the screen will display under the current ambient light, adapted to that ambient light, i.e., the actual RGB value output by the screen.

[0051] In S103, the image to be displayed is shown according to the target RGB value of each pixel.

[0052] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: First, the current ambient light illuminance and current ambient light color temperature of the screen are obtained; then, the target RGB value of each pixel in the image to be displayed is determined based on the current ambient light illuminance and current ambient light color temperature; finally, the image to be displayed is displayed according to the target RGB value of each pixel. Specifically, when determining the target RGB value of each pixel in the image to be displayed, the current ambient light information is incorporated, thereby mitigating the influence of screen-reflected ambient light on the displayed color and ensuring accurate screen color. Thus, even in bright environments, users can experience an excellent visual experience brought by accurate screen color.

[0053] The following is a detailed description of the specific implementation method for determining the target RGB value of each pixel in the image to be displayed based on the current ambient light intensity and current ambient light color temperature in S102. Specifically, it can be achieved by... Figure 2 This is achieved through S1021 and S1022 shown.

[0054] In S1021, the corrected RGB value is determined based on the current ambient illuminance and the current ambient color temperature.

[0055] In this disclosure, a target corrected RGB value corresponding to the current ambient illuminance and the current ambient color temperature can be determined based on a pre-established second correspondence between ambient illuminance, ambient color temperature, and corrected RGB value.

[0056] In S1022, for each pixel in the image to be displayed, the target RGB value of the pixel is determined based on the corrected RGB value and the original RGB value of the pixel.

[0057] In this disclosure, the original RGB value refers to the RGB value of the image to be displayed without color gamut calibration, and it is related to the image to be displayed on the screen. For example, if the image to be displayed is a pure red image, then the original RGB value of any pixel on the display screen is (255, 0, 0).

[0058] Specifically, the target RGB value of a pixel can be determined by combining the corrected RGB value and the original RGB value of the pixel in the following way:

[0059] The actual RGB value corresponding to the target expected RGB value in the pre-built three-dimensional color look-up table (3D-LUT) is determined as the target RGB value of the pixel. The target expected RGB value is the sum of the corrected RGB value and the original RGB value of the pixel.

[0060] In this disclosure, the 3D-LUT includes a first correspondence between desired RGB values ​​and actual RGB values. This first correspondence is constructed based on the condition of shielded ambient light and serves as the basis for color gamut calibration in dark scenes. Using the 3D-LUT, a set of RGB values ​​(i.e., desired RGB values) can be output as another set of RGB values ​​(i.e., actual RGB values), thereby changing the color of the image. The desired RGB values ​​are the original RGB values ​​of the image to be displayed, and the actual RGB values ​​are the RGB values ​​actually output and displayed on the screen.

[0061] For example, the original RGB value of a pixel A in an image to be displayed is (125, 125, 234), which is the expected RGB value. The actual RGB value corresponding to this expected RGB value is (123, 123, 243). Thus, by adjusting the output RGB value of pixel A from (125, 125, 234) to (123, 123, 243), the screen can ensure that the color of pixel A actually seen by the human eye in a dark environment is the color corresponding to the original RGB value (125, 125, 234) of pixel A, thereby achieving color gamut calibration in dark scenes.

[0062] The following section details the method for establishing the second correspondence between ambient illuminance, ambient color temperature, and corrected RGB values ​​in S1021 above. Specifically, it can be achieved through... Figure 3 This is achieved through steps S301 to S303 shown in the diagram.

[0063] In S301, with ambient light blocked, the control screen sequentially displays each color calibration screen in a plurality of color calibration screens, and acquires the first XYZ data of each displayed color calibration screen.

[0064] In this disclosure, shielding from ambient light refers to a dark environment. Multiple color calibration screens may include at least two of a white calibration screen, a red calibration screen, a green calibration screen, a blue calibration screen, a low-grayscale red calibration screen, a low-grayscale green calibration screen, and a low-grayscale blue calibration screen.

[0065] Specifically, in the absence of ambient light, the screen can be controlled to sequentially display each color calibration screen from multiple color calibration screens, and the first XYZ data of each color calibration screen displayed on the screen can be obtained through a sensing module facing the screen. This sensing module can be a camera, illuminance meter, integrating sphere, etc., and can be integrated into the terminal or exist independently of the terminal and connected to it via a wireless or wired network.

[0066] In S302, under different ambient light illuminance and ambient light color temperature, the control screen sequentially displays each color calibration screen and acquires the second XYZ data of each displayed color calibration screen.

[0067] Specifically, under different ambient light levels and different ambient light color temperatures, the screen can be controlled to sequentially display each color calibration image in each color calibration image, and the second XYZ data of each color calibration image displayed on the screen can be obtained through the sensing module facing the screen.

[0068] In S303, based on each first XYZ data and each second XYZ data, a second correspondence between ambient illuminance, ambient color temperature, and corrected RGB values ​​is determined.

[0069] Specifically, based on each first XYZ data obtained in S301 and each second XYZ data obtained in S302, through... Figure 4 S3031 to S3033 shown here determine the second correspondence between ambient light illuminance, ambient light color temperature and corrected RGB values.

[0070] In S3031, based on each first XYZ data and each second XYZ data, a third correspondence is determined between ambient light illuminance, ambient light color temperature, XYZ data under ambient light, and XYZ data under shielded ambient light.

[0071] Specifically, based on each first XYZ data and each second XYZ data, a functional correspondence between the XYZ data under ambient light and the ambient light illuminance, ambient light color temperature, and XYZ data under shielded ambient light can be obtained through data fitting. This functional correspondence is then determined as the third correspondence between ambient light illuminance, ambient light color temperature, XYZ data under ambient light, and XYZ data under shielded ambient light.

[0072] In S3032, based on the mapping matrix from XYZ color space to RGB color space and the third correspondence, the fourth correspondence between ambient light illuminance, ambient light color temperature, RGB values ​​under ambient light, and RGB values ​​under shielded ambient light is determined.

[0073] Specifically, based on the mapping matrix from the XYZ color space to the RGB color space, the XYZ data under ambient light in the third correspondence can be converted into RGB data under ambient light, and the XYZ data under shielded ambient light in the third correspondence can be converted into RGB data under shielded ambient light. This yields a fourth correspondence between ambient light illuminance, ambient light color temperature, RGB values ​​under ambient light, and RGB values ​​under shielded ambient light.

[0074] For example, the functional correspondence (i.e., the third correspondence) between the XYZ data under ambient light and the ambient light illuminance, ambient light color temperature, and XYZ data under shielded ambient light is f([X1, Y1, Z1]) = f([X0, Y0, Z0]) * f(lux) * f(cct). The fourth correspondence between the ambient light illuminance, ambient light color temperature, RGB values ​​under ambient light, and RGB values ​​under shielded ambient light is f([R1, G1, B1]) = f([R0, G0, B0]) * f(lux) * f(cct), where (X1, Y1, Z1) are the XYZ data under ambient light, (X0, Y0, Z0) are the XYZ data under shielded ambient light, lux is the ambient light illuminance, cct is the ambient light color temperature, (R1, G1, B1) are the RGB values ​​under ambient light, and (R0, G0, B0) are the RGB values ​​under shielded ambient light.

[0075] In S3033, based on the fourth correspondence, the second correspondence between ambient illuminance, ambient color temperature, and corrected RGB values ​​is determined.

[0076] In this disclosure, the RGB value is corrected to be the difference between the RGB value under ambient light and the RGB value under shielded ambient light, corresponding to the same ambient light illuminance and ambient light color temperature.

[0077] Specifically, the difference between the R value under ambient light with the same ambient illuminance and ambient color temperature and the R value under shielded ambient light can be determined as the corrected R value, ΔR, for the same ambient illuminance and ambient color temperature; the difference between the G value under ambient light with the same ambient illuminance and ambient color temperature and the G value under shielded ambient light can be determined as the corrected G value, ΔG, for the same ambient illuminance and ambient color temperature; and the difference between the B value under ambient light with the same ambient illuminance and ambient color temperature and the B value under shielded ambient light can be determined as the corrected B value, ΔB, for the same ambient illuminance and ambient color temperature.

[0078] This disclosure also provides a screen display device, such as Figure 5 As shown, the screen display device 500 includes:

[0079] The first acquisition module 501 is configured to acquire the current ambient light illuminance and current ambient light color temperature of the screen;

[0081] Display module 503 is used to display the image to be displayed according to the target RGB value of each pixel determined by the first determining module 502.

[0082] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: First, the current ambient light illuminance and current ambient light color temperature of the screen are obtained; then, the target RGB value of each pixel in the image to be displayed is determined based on the current ambient light illuminance and current ambient light color temperature; finally, the image to be displayed is displayed according to the target RGB value of each pixel. Specifically, when determining the target RGB value of each pixel in the image to be displayed, the current ambient light information is incorporated, thereby mitigating the influence of screen-reflected ambient light on the displayed color and ensuring accurate screen color. Thus, even in bright environments, users can experience an excellent visual experience brought by accurate screen color.
