[0023] According to an embodiment of the present invention, a method for displaying an image on a display screen is provided.

[0024] Figure 1 FIG. 1 is a flow chart of an image display method applied on a display screen according to an embodiment of the present invention. Figure 1 As shown, the invention comprises the following steps:

[0025] Step S101, acquiring a target image displayed on a display screen and initial image information corresponding to the target image, wherein the initial image information at least includes the following information: initial backlight brightness of the target image, and initial pixel color of each pixel in the target image.

[0026] As mentioned above, due to the shape of the eye lens, the human visual field is more similar to a horizontal ellipse. The clearest part of the visual field is the overlapping part of the display screen seen by both eyes, which is approximately circular. Figure 2 As shown, Figure 2 It is a schematic diagram of the area corresponding to the target range in a display screen in an embodiment provided according to the present invention. The display screen is a white rectangular part, and the user's main visual range is an approximately circular part. The method of displaying an image on the display screen in the present application is to reduce the part that other people can see by squinting at the screen from the left and right sides.

[0027] As described above, a target image displayed on a display screen is acquired, for example, the target image is a target image with a resolution of 1920×1080, and initial image information corresponding to the target image is acquired.

[0028] Step S102, obtaining configuration information of the display screen, and determining a target range corresponding to the target image according to the configuration information, wherein the target range is a visible range with the highest priority corresponding to the front viewing angle of the display screen.

[0029] As described above, the target range corresponding to the target image is determined by the configuration information of the display screen. The target range is the highest priority visible range corresponding to the front viewing angle of the display screen. The display screen manufacturer or user can flexibly select the target range to be processed.

[0030] Step S103: Based on the initial image information, the initial image information is adjusted to obtain a target backlight brightness and a target pixel color.

[0031] As mentioned above, the initial image information includes: the initial backlight brightness of the target image and the initial pixel color of each pixel in the target image. The initial image information is adjusted to obtain the target backlight brightness and the target pixel color.

[0032] Step S104, controlling the image within the target range to be displayed according to the target backlight brightness, and controlling the target pixel to be displayed according to the target pixel color, wherein the target pixel is a pixel existing within the target range.

[0033] As described above, the image within the target range is controlled according to the target backlight brightness and the target pixel color and displayed on the display screen.

[0034] Through the above method, the existing display screen design and structure do not need to be changed, there is no increase in hardware cost, no additional power consumption, and the thickness of the display screen does not change. It can meet the trend of thin and light notebook computers. It is realized by digital logic and does not require large-capacity storage and other components. The cost and power consumption of the TCON chip increase very little, and it has strong scalability, low cost, and is easy to implement. The image processing effect is more flexible and the visual experience is better. In this application, since the backlight brightness is reduced, the image in the front visible range is greatly reduced in processing, and the red component part that the human eye is most sensitive to is greatly reduced, so the visual effect is greatly reduced at a side viewing angle, and the anti-peeping function is achieved.

[0035] In an optional example, before obtaining configuration information of a display screen and determining a target range corresponding to a target image based on the configuration information, the method includes: determining a center point of the screen of the display screen; determining the center point as the center of a circle and determining a preset radius, and determining a preset circular area position based on the center of the circle and the preset radius, wherein the preset radius is less than or equal to one half of the shortest side of the display screen; determining the preset circular area position as an information item in the configuration information, and storing the information of the preset circular area position in a preset register.

[0036] As described above, the preset circular area position of the display screen is determined, with the center point of the screen of the display screen as the center of the circle and a length less than or equal to half of the shortest side of the display screen as the radius. The multiple circles formed are the preset circular area positions of the display screen, and the information of the multiple preset circular area positions is stored in a preset register.

[0037] In an optional example, configuration information of the display screen is obtained, and a target range corresponding to the target image is determined according to the configuration information, including: obtaining a preset circular area position from a preset register, and determining the preset circular area position as the target range.

[0038] As described above, information on the positions of the plurality of preset circular areas is stored in a preset register, and the target range is determined based on obtaining the positions of the preset circular areas from the preset register.

[0039] In an optional instance, based on the initial image information, the initial image information is adjusted to obtain the target backlight brightness and the target pixel color, including: adjusting the initial backlight brightness to a preset brightness to obtain the target backlight brightness; based on the initial pixel color, adjusting the proportion of the red component in the target pixel to a preset proportion to obtain the target pixel color.

[0040] As described above, the target backlight brightness is obtained by reducing the initial backlight brightness. Based on the initial pixel color, color conversion is performed so that the target pixel within the target range still maintains the contrast under the initial backlight brightness, and the proportion of the red component in the target pixel is adjusted to a preset proportion to obtain the target pixel color, thereby achieving no visual difference for the user.

[0041] In an optional example, the initial backlight brightness is adjusted to a preset brightness to obtain a target backlight brightness, including: adjusting a duty cycle of a backlight control signal to a preset duty cycle so that the initial backlight brightness is adjusted to the preset brightness, wherein the backlight control signal is used to control the backlight brightness of a target image.

[0042] As mentioned above, the duty cycle refers to the proportion of the power-on time to the total time in a pulse cycle. To obtain the target backlight brightness, the duty cycle of the backlight signal needs to be reduced so that the initial backlight brightness is adjusted to the preset brightness.

[0043] An embodiment of the present invention provides an image display method for application on a display screen, by acquiring a target image displayed on the display screen and initial image information corresponding to the target image, the initial image information comprising at least the following information: an initial backlight brightness of the target image, an initial pixel color of each pixel in the target image; acquiring configuration information of the display screen, and determining a target range corresponding to the target image based on the configuration information, wherein the target range is a visible range with the highest priority corresponding to the front viewing angle of the display screen; adjusting the initial image information based on the initial image information to obtain a target backlight brightness and a target pixel color; controlling an image within the target range to be displayed according to the target backlight brightness, and controlling a target pixel to be displayed according to the target pixel color, wherein the target pixel is a pixel existing within the target range, thereby solving the problem in the related art of realizing the anti-peeping function of the display screen by usually adding additional hardware, thereby achieving a more flexible image processing effect and a better visual experience.
