[0020] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0021] See also Figure 1 , Figure 1A flow chart of a control method for a lifting transparent display screen provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the control method of the lifting transparent display screen provided in the embodiment of the present application includes steps S1 to S4.

[0022] Step S1: acquiring an initial image, and performing spectral characteristic correction on the initial image based on a preset spectral characteristic correction algorithm to obtain a target image.

[0023] Specifically, for each initial pixel of the initial image, spectral characteristic correction is performed on the initial pixel based on the spectral characteristic correction algorithm; the initial pixels after each correction constitute the target image; The step of performing spectral characteristic correction on the initial pixel based on the spectral characteristic correction algorithm comprises the following steps: Acquire initial primary color light mixing information of the pixel; wherein the initial primary color light mixing information includes initial color components of each primary color light; the initial primary color light mixing information is initial RGB color space information of the pixel, including an initial red component, an initial green component, and an initial blue component; For each of the primary color lights, the initial color component of the primary color light is corrected based on the transmittance and reflectance of the primary color light relative to the lifting transparent display screen to obtain the corrected color component of the primary color light, and the corrected color component is processed for validity to obtain the first intermediate color component corresponding to the primary color light; specifically, for each of the primary color lights, the ratio of the initial color component of the primary color light to the sum of the transmittance and the reflectance is calculated, and the ratio is rounded to obtain the corrected color component; it is determined whether the corrected color component is greater than 255; if the corrected color component is greater than 255, the first intermediate color component of the primary color light is determined to be 255; if the corrected color component is not greater than 255, the first intermediate color component of the primary color light is determined to be the corrected color component; for example, the transmittance is 0.6, the reflectance is 0.1, and the initial color component of the primary color light is 200, then the ratio of the initial color component of the primary color light to the sum of the transmittance and the reflectance is , the correction color component is 286, and the first intermediate color component of the primary light is 255; for another example, the transmittance is 0.65, the reflectance is 0.08, and the initial color component of the primary light is 150, then the ratio of the initial color component of the primary light to the sum of the transmittance and the reflectance is , the correction color component is 205, and the first intermediate color component of the primary color light is 205.

[0024] The initial pixel is color corrected based on the first intermediate color components corresponding to the primary color lights.

[0025] It can be understood that when a transparent display screen transmits light, due to the absorption and scattering of light by the display screen, the intensity of light passing through the display screen will be weakened, the transmittance is less than 1, and part of the incident light is reflected on the surface of the display screen and cannot pass through the display screen, and the reflectivity is greater than 0. Therefore, directly displaying the original image on the transparent display screen will cause the actual light signal intensity reaching the audience's eyes to decrease, the color to become darker and distorted. Step S1 is used to reversely compensate the initial primary color light mixing information corresponding to each pixel to ensure that after optical loss, the output light signal intensity meets expectations.

[0026] Step S2: optimizing the transparency of the target image based on a preset transparency optimization algorithm to obtain a transparency optimized image.

[0027] Specifically, step S2 includes the following steps: For each target pixel of the target image, the transparency of the target pixel is optimized based on the transparency optimization algorithm; the target pixels after each optimization constitute the transparency optimized image; The step of optimizing the transparency of the target pixel based on the transparency optimization algorithm includes: Calculating the significance value corresponding to each first intermediate color component of the target pixel based on the first intermediate primary color mixing information of each target pixel adjacent to the target pixel; specifically, for each first intermediate color component of the target pixel, calculating the average value of the first intermediate color components corresponding to each target pixel adjacent to the target pixel, calculating the absolute value of the difference between the first intermediate color component of the target pixel and the average value, and taking the ratio of the absolute value to the maximum color component as the significance value of the first intermediate color component; wherein the maximum color component is 255; For each first intermediate color component of the target pixel, the transparency corresponding to the first intermediate color component is determined based on the significance value corresponding to the first intermediate color component, the minimum transparency and the maximum transparency of the lifting transparent display screen, and the optimized color component corresponding to the first intermediate color component is determined based on the transparency, and the optimized color component is processed for validity to obtain the second intermediate color component corresponding to the first intermediate color component; specifically, the significance value is multiplied by the difference between the maximum transparency and the minimum transparency to obtain a target product; the average value of the maximum transparency and the minimum transparency is subtracted from the target product to obtain the transparency; the transparency is multiplied by the first intermediate color component to obtain the optimized color component; the optimized color component is rounded to obtain the second intermediate color component; The target pixel is color optimized based on each second intermediate color component corresponding to the target pixel.

[0028] It can be understood that step S2 calculates each significance value of the target pixel through the neighborhood color information of the target pixel for each target pixel, and performs color optimization on the target pixel based on the significance values ​​corresponding to the target pixel, thereby achieving transparency optimization processing of the target pixel, effectively improving the color reproduction and clarity of the image, while taking into account the transparency of the screen.

[0029] Step S3: performing color compensation on the transparency-optimized image based on a preset color compensation algorithm to obtain an image to be displayed.

[0030] Specifically, step S3 includes the following steps: For each optimized pixel of the transparency optimized image, color compensation is performed on the optimized pixel based on the color compensation algorithm, and the optimized pixels after each color compensation constitute the image to be displayed; The step of performing color compensation on the optimized pixel based on the color compensation algorithm includes: The second intermediate primary color light mixing information corresponding to the optimized pixel is converted into the LAB color space to obtain the first LAB color space information; wherein the first LAB color space information includes brightness , the color component between the positive red direction and the negative green direction , the color component between the positive yellow direction and the negative blue direction ; The initial primary color light mixing information corresponding to the optimized pixel is converted into the LAB color space to obtain the ideal LAB color space information corresponding to the optimized pixel; the ideal LAB color space information includes brightness , the color component between the positive red direction and the negative green direction , the color component between the positive yellow direction and the negative blue direction ; Obtain a first difference value between the first LAB color space information and the ideal LAB color space information; specifically, using Obtaining the first difference value; wherein, is the first difference value; The first LAB color space information is color compensated based on the first difference value to obtain the first LAB color space information after color compensation; specifically, using Performing color compensation on the first LAB color space information, wherein: is the first LAB color space information after color compensation, is the first LAB color space information; Convert the first LAB color space information after color compensation into RGB color space to obtain the first target primary color light mixing information corresponding to the optimized pixel; The first target primary color light mixing information is converted into a LAB color space to obtain second LAB color space information; wherein the second LAB color space information includes brightness , the color component between the positive red direction and the negative green direction , the color component between the positive yellow direction and the negative blue direction ; Obtain a second difference value between the second LAB color space information and the ideal LAB color space information; specifically, using Obtain the second difference value; wherein, is the second difference value; comparing the second difference value with a preset difference threshold; If the second difference value is less than the preset difference threshold, color compensation is performed on the optimized pixel based on the first target primary color light mixing information; If the second difference value is not less than the preset difference threshold, color compensation is performed on the second LAB color space information based on the second difference value to obtain the second LAB color space information after color compensation; specifically, using Performing color compensation on the first LAB color space information, wherein: It is the second LAB color space information after color compensation. is the second LAB color space information; Convert the second LAB color space information after color compensation into RGB color space to obtain the second target primary color light mixing information corresponding to the optimized pixel; Performing LAB color space conversion on the second target primary color light mixing information to obtain third LAB color space information; Obtaining a third difference value between the third LAB color space information and the ideal LAB color space information; iterating the steps after obtaining the second difference value between the second LAB color space information and the ideal LAB color space information until final target primary color light mixing information is obtained, and the difference value corresponding to the final target primary color light mixing information is less than the preset difference threshold; The optimized pixel is color compensated based on the final target primary color light mixing information.

[0031] It can be understood that step S3 performs iterative color compensation processing on the transparency optimized image based on a preset color compensation algorithm, which significantly improves the color restoration and display quality of the image and helps to improve the color distortion problem caused by transparency optimization.

[0032] Step S4, obtaining the position and rising speed of the liftable transparent display screen, and displaying the image to be displayed on the liftable transparent display screen based on the position and the rising speed.

[0033] Specifically, step S4 includes the following steps: Constructing a mapping function between display content and time corresponding to the image to be displayed based on the position and the rising speed; The image to be displayed is displayed on the lifting transparent display screen based on the mapping function.

[0034] The method provided in this embodiment achieves compatibility of high color reproduction and transparency of the lifting transparent display screen by correcting the spectral characteristics, optimizing transparency and color compensation of the initial image, which not only improves the display quality of the image, but also enhances the user's visual experience.
