In some embodiments of the present application, a display method is provided, the display method is performed by an electronic device, fig. 1A and 1B show schematic structural diagrams of the electronic device of some embodiments of the present application, and as shown in fig. 1A and 1B, the electronic device 100 includes a first folding screen 102 and a second folding screen 104. Fig. 2 shows a flowchart of a display method according to some embodiments of the present application, as shown in fig. 2, the display method includes:
Step 202, under the condition that the first folding screen and the second folding screen are in a folding state, obtaining folding angle information between the first folding screen and the second folding screen.
In this embodiment of the present application, the folding screen of the electronic device includes a first folding screen and a second folding screen, and, for example, as shown in fig. 1A, the folding manner of the first folding screen 102 and the second folding screen 104 is a left-right bending folding, or, as shown in fig. 1B, the folding manner of the first folding screen 102 and the second folding screen 104 is an up-down bending folding.
Under the condition that a first folding screen and a second folding screen of the folding screen mobile phone are in a folding state, the folding angles between the first folding screen and the second folding screen and between the second folding screen are obtained. Illustratively, the folding angle is an angle between a display side of the first folding screen and a display side of the second folding screen. Illustratively, the fold angle is angle α shown in FIG. 1B.
Step 204, determining first ambient light intensity information corresponding to the first folding screen and second ambient light intensity information corresponding to the second folding screen according to the folding angle information.
In this application embodiment, when first folding screen and second folding screen are in the folded state, first folding screen and second folding screen's orientation is different, therefore under the same ambient light source, like under sunshine, the incident angle when ambient light shines first folding screen and second folding screen is different, consequently probably can form different ambient light influences on first folding screen and second folding screen, and the ambient light intensity of first folding screen and the ambient light intensity of second folding screen are different promptly.
Therefore, according to the embodiment of the application, according to the folding angle of the folding screen mobile phone, the first ambient light intensity information on the first folding screen and the second ambient light intensity information on the second folding screen are respectively determined, and the real result of the influence of ambient light on each folding screen can be obtained.

In the embodiment of the present application, the color compensation parameters specifically include a color correction curve, a saturation correction curve, a contrast adjustment parameter, and the like.
Specifically, the X, Y, and Z values of the XYZ Color Space (CIE 1931 Color Space) are also referred to as tristimulus values, and the X, Y, and Z values can be obtained by 3×3 matrix conversion in the RGB Color Space (RGB Color Space), wherein the first column of the 3×3 matrix is a conversion coefficient of R corresponding to the target Color, the second column is a conversion coefficient of G corresponding to the target Color, and the third column is a conversion coefficient of B corresponding to the target Color.
After determining the tristimulus values X, Y and Z of the target colors, the display device may confirm the X ', Y' and Z 'values actually displayed by all colors according to the average picture level (Average Picture Level, APL) of the current screen display, where the Y' value may correspond to the brightness.
The color coordinates XY of the color can also be normalized according to the following formulas (1), (2), (3) and (4), when the three-dimensional XYZ color space becomes an "XY chromaticity diagram" (XY color diagram) of the two-dimensional XY plane:
Z＝1-X-Y(1)；
where X, Y, Z is the X, Y and Z values of the image in XYZ color space.
According to the ambient illuminance E, the brightness value of the ambient light received by the human eye when the ambient light is reflected by the screen can be calculated according to the formula (5):
Y0 ＝ E × R÷π (5)；
wherein Y0 is the brightness value of the ambient light received by the human eye, E is the ambient light intensity, R is the screen reflectivity, and pi is the circumference ratio.
According to the ambient light color coordinate xy and the Y value of the ambient light, the Yxy value of the ambient light can be obtained. After converting it back to the XYZ domain, the tristimulus values X ", Y" and Z "of the reflected light are obtained, the tristimulus values of the reflected light are added to the values of X ', Y ', Z ' actually displayed with the color, the tristimulus values after fading, i.e., X ' +X ', Y ' +Y ', and Z ' +Z ', which are actually accepted by the human eye, can be obtained and used as the basis for color display correction.
Optionally, the color compensation process includes:
1a, the display device determines a target color temperature from the color temperature of the ambient light and the color temperature compensation curve and adjusts the color temperature of the image to the target color temperature.
2a, the display device determines the target saturation according to the target brightness and the ratio of the brightness to the saturation, and adjusts the saturation of the image to the target saturation.
3a, the display device calculates R, G and B ranges of variation, respectively, based on RGB (Red, green, blue) values of ambient light, and adjusts RGB values of white balance of the image accordingly, based on R, G and B ranges of variation.
4a, the display device acquires the coordinates of R, G and B of the target color, and determines the coordinates of Cyan (Cyan, C), magenta (M) and Yellow (Y) of the target color; and determining the R coordinate, the G coordinate, the B coordinate, the C coordinate, the M coordinate and the Y coordinate of the target color according to the RGB variation range of the target color, so as to adjust to the RGB value corresponding to R, G, B, C, M, Y.
Optionally, the color compensation process includes:
1b, using a color compensation scheme in a uniform color space, such as IPT (Intensity Protan Tritan) space, using the resolved reflected light intensity and color information to compensate for color shifts due to bleaching effects. A compensation mode based on the tristimulus values of human eyes and the IPT space is more uniform in color perception.
2b, dynamically expanding the color gamut, e.g. from sRGB to Adobe RGB, based on the received ambient light intensity, and compensating the color to a more saturated position. The scheme is a color compensation scheme of Yxy domain for OLED (Organic Light-Emitting Diode) screen reflection problem, and the compensation based on color coordinates can simultaneously process hue and saturation offset.
3b, CNN (Convolutional Neural Networks, convolutional neural network) based on deep learning, DNN (Deep Neural Networ, deep neural network), transducer model or GAN (Generative Adversarial Networks, generating countermeasure network) and other AI (Artificial Intelligence ) algorithm schemes, which can be trained by a large amount of data according to the detected ambient light, and adaptively adjust the optimal display color of the image.

After the first ambient light intensity information is detected, the ambient light intensity information irradiated onto the second folding screen, that is, the second ambient light intensity information is calculated based on the folding angle between the first folding screen and the second folding screen.
The second angular threshold range is in particular an acute angular threshold range, i.e. a range of 0 ° to 90 °. Specifically, fig. 4 illustrates a schematic view of illumination of a folding screen according to some embodiments of the present application, as shown in fig. 4, when a folding angle α between a first folding screen 402 and a second folding screen 404 is an acute angle, light intensity of light source 406 irradiated onto the first folding screen is first ambient light intensity information, and light intensity of light source 406 irradiated onto the second folding screen is second ambient light intensity information.
