Figure 4As shown, the system is divided into four layers, from top to bottom: the Applications layer (referred to as the "Application Layer"), the Application Framework layer (referred to as the "Framework Layer"), the Android runtime and system library layer (referred to as the "System Runtime Layer"), and the kernel layer.

The image adjustment application allows users to adjust the brightness and color of the image display in the light reflection area through touch operations, thus adjusting the effect of the displayed image.
[0069] In existing technologies, each LED pixel in a reflective display has a square reflector cup with a light-emitting aperture. This enlarges the pixel area, reduces the pixel pitch, and improves the pixel aperture ratio or fill factor, eliminating the graininess problem of LED displays. This results in a softer image, reducing eye strain from prolonged viewing and effectively protecting eyesight. Reflective displays achieve their display effect by reflecting ambient light; therefore, they are highly susceptible to changes in ambient light. When strong light shines around a reflective display, it will produce brighter reflective areas with uneven brightness and color, affecting the image display quality.
[0070] To address the problem of uneven brightness and color in the displayed image caused by light reflection in existing reflective display devices, this application provides a display device, a method and apparatus for adjusting the reflectivity of a display screen. The method determines the coordinates of a target reflection point based on the obtained three-dimensional coordinates of the target human eye image and the target light source image, where the target reflection point is the reflection point of the target light source image on the display screen. A target reflection area is determined with the target reflection point as the center based on a preset radius parameter. The reflectivity of all pixels in the target reflection area is reduced, and an adjusted image is generated based on the reduced reflectivity of all pixels in the target reflection area. This improves the problem of uneven brightness and color in the displayed image caused by light reflection, thereby enhancing the image display effect of the reflective display.
[0071] The technical solutions of this application will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0072] Figure 6 This is a schematic diagram of the structure of a display device provided in an embodiment of the present invention, such as... Figure 1As shown, the display device includes an image acquisition device 100, a central processing unit (CPU) 200, and a display screen 300. The image acquisition device 100 can acquire images of the external environment of the display device. When the image acquisition device 100 also includes a processor, an Artificial Intelligence (AI) algorithm is pre-installed in the processor. Based on the AI algorithm, the acquired environmental image is identified. When a target human eye image and a target light source image are identified in the external environment image, the distance to the target human eye image and the target light source image is obtained through a distance testing sensor integrated in the image acquisition device 100. The three-dimensional angles of the target human eye image and the target light source image are obtained through a rotation angle adjustment process. According to the pre-installed program in the processor, the three-dimensional coordinate values of the target human eye image and the target light source image are obtained based on their distance, three-dimensional angle, and three-dimensional angle. The image acquisition device 100 sends the obtained three-dimensional coordinate values of the target human eye image and the target light source image to the CPU 200. The central processing unit (CPU200) determines the coordinates of the target reflection point based on the obtained three-dimensional coordinates of the target human eye image and the target light source image, where the target reflection point is the reflection point of the target light source image on the display screen. It then determines the target reflection area centered on the target reflection point according to a preset radius parameter. The CPU200 reduces the reflection level of all pixels in the target reflection area and generates an adjusted image based on the reduced reflection level of all pixels in the target reflection area. The CPU200 sends the adjusted image to the display screen for display.
[0073] For example, the image acquisition device is a smart camera. The smart camera integrates a depth-measuring sensor and has a pre-installed AI recognition algorithm for images in its processor. This algorithm can identify the target image (human eye image) and the target light source image in the image. The depth-measuring sensor then obtains the distance between the smart camera and the target corresponding to the human eye image and the target corresponding to the target light source image. For example, the target light source image can be a lamp or other light source device. After identifying the target image or target light source image, the image acquisition device adjusts the angle to restore the camera angle to its original position. During the angle adjustment process, the change in angle is recorded, and the three-dimensional angle of the target image or target light source image is obtained based on this change. The smart camera also has a pre-installed program that can obtain the three-dimensional coordinates of the target image and the target light source image based on the distance between the target image and the target light source image, and the three-dimensional angle of the target image and the target light source image. In this invention, the methods of measuring the distance between the target human eye image and the target light source image by the image acquisition device, identifying the target human eye image and the target light source image in the image according to the artificial intelligence recognition algorithm, and calculating the three-dimensional coordinate values and the three-dimensional coordinate values of the target light source image are all methods that have been implemented in the prior art, and will not be described in detail here.
[0074] Figure 7 A flowchart illustrating the display screen reflectance adjustment method provided in this embodiment of the invention. Figure 1 The execution entity in this embodiment can be Figure 6 The controller in the illustrated embodiment. (As shown) Figure 7 As shown, the method includes:
[0075] S701: Receives the three-dimensional coordinates of the target human eye image and the target light source image, and determines the coordinates of the target reflection point based on the obtained three-dimensional coordinates of the target human eye image and the target light source image.
[0076] In this embodiment of the invention, after receiving the three-dimensional coordinates of the target human eye image and the target light source image sent by the image acquisition device, the coordinates of the reflection points of the target human eye image and the target light source image on the display screen are determined according to the principle of light reflection. For example, Figure 8 This is a schematic diagram of the target reflection point provided in an embodiment of the present invention. Figure 8 As shown, with the lower right corner of the display screen as the origin of the three-dimensional coordinate axis, when the three-dimensional coordinates of the target human eye image A point are (x1, y1, z1) and the three-dimensional coordinates of the target light source image B point are (x2, y2, z2), the coordinate values of the target reflection point C (x, y, 0) are obtained according to the three-dimensional coordinates of the target human eye image A and the three-dimensional coordinates of the target light source image B point, as shown in formula (1):
[0077]
[0078] Specifically, by substituting the three-dimensional coordinates (x1, y1, z1) of point A and the three-dimensional coordinates (x2, y2, z2) of point B into formula (1), the relationship between x and y in the three-dimensional coordinates of the target reflection point C can be obtained. For example, the expression for the relationship between x and y is y = f(x).
[0079] For example, the display area of the screen is divided into M*N display points, with the lower right corner of the screen as the origin of the three-dimensional coordinate axis, and the coordinate values of each display point are obtained. If the coordinate value of point Q is (x4, y4) among all display points, the x-coordinate value x4 of point Q is substituted into f(x) to obtain the corresponding y-coordinate value y5. If the difference y4 between y5 and the y-coordinate value of point Q itself is the smallest among all display points, that is, point Q is the display point that best fits the relationship y = f(x) among all display points, the x-coordinate x4 and y4 of point Q are used as the x-coordinate and y-coordinate of the target reflection point C(x, y, 0).
[0080] S702: Determine the target reflection zone with the target reflection point as the center based on the preset radius parameter.
[0081] In this embodiment of the invention, the center point of the light reflection area is the target reflection point. Therefore, after determining the coordinates of the target reflection point on the display screen, the target reflection area can be determined with the target reflection point as the center according to the preset radius parameter. Figure 9 Schematic diagram of the target reflection area provided in the embodiments of the present invention Figure 1 Specifically, such as Figure 9 As shown, the circular area is defined as the target reflection zone, with the target reflection point as the center and a preset radius parameter as the radius.
[0082] For example, the radius of the target reflective area can also be adjusted by allowing the user to set a preset radius parameter. Specifically, a display image adjustment application is pre-installed in the display device. The user can input the target radius of the reflective area through the display image adjustment application, which then generates a reflective area radius confirmation command based on the user-input target radius. After the controller receives the reflective area radius confirmation command, it determines the target reflective area with the target reflection point as the center based on the target radius.
[0083] S703: Reduce the reflectance of all pixels in the target reflective area, and generate an adjusted image based on the reduced reflectance of all pixels in the target reflective area.
[0084] In this embodiment of the invention, after determining the range of the target reflective area, the brightness and chromaticity of the image displayed in the light reflective area can be adjusted by reducing the reflectance of all pixels in the target reflective area. For example, the reflectance of all pixels in the target reflective area can be reduced according to a target reflectance reduction magnitude, where the target reflectance reduction magnitude is a pre-stored reflectance reduction magnitude. Specifically, the target reflectance reduction magnitude is set according to the hardware characteristics of the display device and preset in the display device. Different models of display devices may have different target reflectance reduction magnitudes. Specifically, by determining the grayscale value variable corresponding to the preset reflectance, the grayscale value of all pixels in the target reflective area is adjusted according to the determined grayscale value variable to achieve the purpose of reducing the reflectance of all pixels. In this embodiment of the invention, an adjusted image is generated based on the reduced reflectance of all pixels in the target reflective area, and the generated adjusted image is sent to the display screen for display, improving the display effect of the light reflective area.
[0085] For example, the reduction in reflection in the target reflective area can also be adjusted by allowing the user to set the target reflection reduction magnitude. Specifically, a display image adjustment application is pre-installed in the display device. The user can input the target reflection reduction magnitude through the display image adjustment application, which then generates a reflection reduction magnitude confirmation command based on the user-input target reflection reduction magnitude. After the controller receives the reflection reduction magnitude confirmation command, it reduces the reflection of all pixels in the target reflective area according to the target reflection reduction magnitude.
[0086] In this embodiment of the invention, after determining the target reflection area, the brightness and chromaticity of the light reflection area can be adjusted by reducing the reflection amount of all pixels contained in the target reflection area. For example, the reflection amount of all pixels in the target reflection area can be reduced by a preset reflection reduction amplitude.
[0087] The display screen reflectance adjustment method provided in this embodiment determines the coordinates of the target reflection point based on the obtained three-dimensional coordinates of the target human eye graphic and the target light source graphic, wherein the target reflection point is the reflection point of the target light source graphic on the display screen; the target reflection area is determined with the target reflection point as the center according to a preset radius parameter; the reflectance of all pixels in the target reflection area is reduced, and an adjusted image is generated based on the reduced reflectance of all pixels in the target reflection area, thereby adjusting the brightness and chromaticity of the image displayed in the light reflection area and improving the display effect of video and images.
[0088] Figure 10 A flowchart illustrating the display screen reflectance adjustment method provided in this embodiment of the invention. Figure 2 In this embodiment of the invention, in Figure 7Based on the provided embodiments, another method for reducing the reflectivity of all pixels in the target reflective area in S702 is described in detail. For example... Figure 10 As shown, the method includes:
[0089] S1001: Obtain the target distance between all pixels contained in the target reflection area and the target reflection point.
[0090] In this embodiment of the invention, considering that the brightness of light refraction gradually decreases from the center point to the edge area within the light reflection area, the target reduction magnitude of the reflection amount corresponding to pixels at different positions in the target reflection area can be adjusted according to the changing trend of the light reflection amount. Specifically, the target reduction magnitude of the reflection amount is adjusted based on the distance between the pixel and the target reflection point. Specifically, the target distance corresponding to the pixel is determined based on the coordinate values of the pixel and the target reflection point, thereby obtaining the target distances corresponding to all pixels in the target reflection area.
[0091] S1002: Determine the target reduction magnitude corresponding to the target distance of each pixel according to the preset relationship function, and reduce the reflection of each pixel according to the target reduction magnitude corresponding to each pixel.
[0092] In this embodiment of the invention, the target reduction magnitude corresponding to the target distance of each pixel can be determined according to a preset relationship function. For example, according to the preset relationship function, when the target distance of a pixel is greater than n times the distance threshold and less than or equal to n+1 times the distance threshold, the target reduction magnitude is set to the (n+1)th reduction magnitude, where n is 0 or a positive integer, and the (n+1)th reduction magnitude is less than or equal to the nth reduction magnitude. Figure 11 Schematic diagram of the target reflection area provided in the embodiments of the present invention Figure 2 .like Figure 11 As shown, when the target distance of a pixel is greater than 0 and less than or equal to a distance threshold (i.e., the pixel is located in the first ring), the target reduction magnitude of that pixel is set to a first reduction magnitude. When the target distance is greater than the distance threshold and less than or equal to twice the distance threshold (i.e., the pixel is located in the second ring), the target reduction magnitude of that pixel is set to a second reduction magnitude. For example, the second reduction magnitude is less than or equal to the first reduction magnitude. When the second reduction magnitude equals the first reduction magnitude, the target reduction magnitude corresponding to pixels in each ring is the same. When the second reduction magnitude is less than the first reduction magnitude, the target reduction magnitude corresponding to pixels in the outer ring is less than that corresponding to pixels in the inner ring, and the target reduction magnitude is larger for rings closer to the center.
[0093] In this embodiment of the invention, the horizontal axis of the preset relationship function is the target distance between each pixel and the target reflection point, and the vertical axis is the target reduction magnitude corresponding to that pixel. When the (n+1)th reduction magnitude is less than the nth reduction magnitude (i.e., the target reduction magnitude corresponding to the pixels in the outer ring is less than the target reduction magnitude corresponding to the pixels in the inner ring), and when the (n+1)th reduction magnitude is equal to the nth reduction magnitude (i.e., the target reduction magnitude corresponding to the pixels in each ring is the same), the target reduction magnitude is equal to the target reduction magnitude.
[0094] The display screen reflection adjustment method provided in this embodiment analyzes the characteristics of light reflection variation, adjusts the reflection reduction amplitude corresponding to pixels at different positions, improves the accuracy of the determined reflection reduction amplitude, improves the problem of uneven brightness and color of the displayed image caused by light reflection, and improves the image display effect of the reflective display.

Figure 3 In this embodiment of the invention, in Figure 7 Based on the provided embodiments, the image acquisition device also integrates a brightness sensor for acquiring the brightness of the target light source corresponding to the target light source image, and sends the acquired brightness of the target light source to the controller. In this embodiment of the invention, another method for reducing the reflection of all pixels in the target reflection area in S703 is described in detail. For example... Figure 12 As shown, the method includes:
[0096] S1201: Receive the brightness of the target light source corresponding to the target light source pattern, and determine the magnitude of the reduction in reflection corresponding to the brightness of the target light source according to a preset brightness function.
[0097] In this embodiment of the invention, considering the influence of the light source's brightness on the brightness of the image displayed in the light reflection area, the magnitude of the reduction in reflection corresponding to the brightness of the target light source can be determined according to a preset brightness function. For example, the preset brightness function can be set to a linear function, meaning the brightness of the light source and the magnitude of the reduction in reflection are linearly related. For example, the preset brightness function can be set to a non-linear function, meaning the magnitude of the reduction in reflection decreases as the brightness of the light source increases.
