The present disclosure relates to communication technology, and more particularly, to a method for determining a compensation value for a local display region, a screen display method, and a terminal device.
With the development of terminal, an under-screen camera appears. The under-screen camera is a camera formed by reducing a pixel density of a screen region over the camera to improve transmittance of the screen region, which does not require a hole for mounting the camera in the screen.
However, since the pixel density of the screen region over the camera is lower, an effective display pixel area of the screen region will be reduced, thereby causing a significant display effect difference between the screen region and other screen regions.
In view of the above, an embodiment of the present disclosure provides a method for determining a compensation value for a local display region, wherein the method is applied to a terminal device equipped with a screen to be compensated, and comprises:
An embodiment of the present disclosure provide a screen display method applied to a terminal device comprising a screen to be compensated, the screen display method comprising:

Thus, a feature that limited by “first”, “second”, or the like may expressly or implicitly include one or more of the features. In the description of the present disclosure, the meaning of “a/the plurality of” is two or more, unless otherwise specifically defined.
Embodiments of the present disclosure are directed to a method and an apparatus for determining a local display region compensation value, a storage medium, and a terminal device.
Referring to
At Step S101, a screen to be compensated is turned on, and the screen to be compensated includes an aperture region and a non-aperture region.
Referring to
In an embodiment of the present disclosure, Step S101 includes turning on the screen to be compensated, and displaying a same content in both the aperture region and the non-aperture region. For example, both the aperture region and the non-aperture region display a pure color. In this way, the subsequent step of determining display ratio between the aperture region and the non-aperture region and calculating the compensation value may be made more accurate without being disturbed by the difference in the display content.
At Step S102, a first display data of the aperture region and a second display data of the non-aperture region when the screen to be compensated is turned on are obtained.
In some embodiments, Step S102 may include:
Specifically, the present disclosure is described by using the display data in the Lxy color space as an example. First, the obtained image data may be converted from the RGB color space to the XYZ color space, and then from the XYZ color space to the Lxy color space. Since the RGB color space, the XYZ color space, and the Lxy color space are all well-known color spaces, the conversion formula between the RGB color space, the XYZ color space, and the Lxy color space is a well-known technique, and details are not described herein.
At Step S103, based on the first display data and the second display data, display ratio between the aperture region and the non-aperture region is determined.
The display data in the Lxy color space includes luminance L and chromaticity coordinates (x, y). Therefore, in an embodiment, the first display data includes a first luminance value L1 and a first chromaticity coordinate (x1, y1), and the second display data includes a second luminance value L2 and a second chromaticity coordinate (x2, y2). Step S103 may include Substep 1-1 and Substep 1-2.
At Substep 1-1, based on the second luminance value and the first luminance value, a luminance ratio of the non-aperture region to the aperture region when the screen to be compensated is turned on is determined.
In an embodiment, the luminance ratio of the non-aperture region to the aperture region is identified in a linear relationship, that is, a L1=L2. Substep 1-1 may include: dividing the first luminance value L1 by the second luminance value L2 to obtain the luminance ratio of the non-aperture region to the aperture region.
At Substep 1-2, based on the first chromaticity coordinate and the second chromaticity coordinate, a chromaticity ratio of the non-aperture region to the aperture region when the screen to be compensated is turned on is determined.
The chromaticity ratio of the non-aperture region to the aperture region may be obtained by the equation √{square root over ((x1−x2)2+(y1−y2)2)}.
At Step S104, based on the display ratio, a compensation value for performing display compensation on the aperture region is calculated.
In an embodiment, Step S104 may include Substep 2-1 to Substep 2-4:
At Substep 2-1, It is determined whether the luminance ratio is smaller than a preset luminance ratio.
The preset luminance ratio is a critical value for determining whether the difference between the displayed luminance of the aperture region and the displayed luminance of the non-aperture region is obvious, and is affected by the type of the screen to be compensated and the pixel density. Therefore, the present disclosure is not limited thereto. It will be readily appreciated that if the luminance ratio is less than the preset luminance ratio, it may be considered that the luminance difference between the aperture region and the non-aperture region is not obvious, that is, visual difference between the aperture region and the non-aperture region cannot be perceived by naked eyes. Therefore, there is no need to compensate the luminance data of the aperture region. If the luminance ratio is not less than the preset luminance ratio, it is considered that there is an obvious luminance difference between the aperture region and the non-aperture region, that is, the visual difference between the aperture region and the non-aperture region may be obviously perceived by the naked eye, so that the luminance data of the aperture region needs to be compensated.
At Substep 2-2, If the luminance ratio is not less than the preset luminance ratio, the luminance ratio is logarithmically calculated according to the preset logarithmic function to obtain a luminance compensation value.
The luminance compensation value is a compensation value for the red component in the image data.
The preset logarithmic function is a logarithmic function for converting the display data from the RGB color space to the Lxy color space, and is not enumerated herein.
At Substep 2-3, it is determined whether the chromaticity ratio is smaller than a preset chromaticity ratio.
The preset chromaticity ratio is a critical value for determining whether the difference between the displayed chromaticity of the aperture region and the displayed chromaticity of the non-aperture region is obvious, and is affected by the type of the screen to be compensated and the pixel density. Therefore, the present disclosure is not limited thereto. It will be readily appreciated that if the chromaticity ratio is less than the preset chromaticity ratio, it may be considered that the chromaticity difference between the aperture region and the non-aperture region is not obvious, that is, the visual difference cannot be perceived by the naked eye. Therefore, it is not necessary to compensate the chromaticity data of the aperture region. If the chromaticity ratio is not less than the preset chromaticity ratio, it is considered that there is an obvious chromaticity difference between the aperture region and the non-aperture region, that is, the visual difference between the aperture region and the non-aperture region can be obviously perceived by the naked eye, so that the display data of the aperture region needs to be compensated.
At Sub step 2-4, if the chromaticity ratio is not less than the preset chromaticity ratio, a chromaticity compensation value is determined from the first chromaticity coordinate and the second chromaticity coordinate.
In some embodiments, Substep 2-4 may include:
Substep 2-4-1: calculating a first ratio of a second horizontal coordinate in the second chromaticity coordinate to a first horizontal coordinate in the first chromaticity coordinate, and performing a logarithmical calculation on the first ratio according to a preset logarithmic function to obtain a first chromaticity compensation value; and
Substep 2-4-1: calculating a second ratio between a second vertical coordinate in the second chromaticity coordinate and a first vertical coordinate in the first chromaticity coordinate, and performing a logarithmical calculation on the second ratio according to a preset logarithmic function to obtain a second chromaticity compensation value.
The first chromaticity coordinate is (x1, y1), and the second chromaticity coordinate is (x2, y2). Therefore, the first ratio (x2/x1) of the second horizontal coordinate in the second chromaticity coordinate to the first horizontal coordinate in the first chromaticity coordinate is calculated, and then the logarithmical calculation is performed on the first ratio (x2/x1) according to a preset logarithmic function. The second ratio (y2/y1) between the second vertical coordinate in the second chromaticity coordinate and the first vertical coordinate in the first chromaticity coordinate, and then the logarithmical calculation is performed on the second ratio (y2/y1) according to a preset logarithmic function to obtain the first and second chromaticity compensation values. The first chromaticity compensation value is a compensation value for the green component in the image data, and the second chromaticity compensation value is a compensation value for the blue component in the image data.
It should be noted that Substep 2-4-1 and Substep 2-4-2 may be performed in parallel or sequentially, and this is not limited in the present disclosure.
In some embodiments, the method may further include: after step S104, performing screen display, that is, displaying contents in the screen, according to the compensation value, and returning to the Step S102 of obtaining the first display data of the aperture region and the second display data of the non-aperture region when the screen to be compensated is turned on, until the luminance ratio is less than the preset luminance ratio, and the chromaticity ratio is less than the preset chromaticity ratio.
Since the pixel difference between the aperture region and the non-aperture region is larger, the display difference is also larger. After one calculation, a certain display difference may still occur in the actual display. For better display effect, the screen display is performed according to the compensation value, and then Step S101 to Step S104 are repeated until the luminance ratio is smaller than the preset luminance ratio and the chromaticity ratio is smaller than the preset chromaticity ratio. In this way, the actual difference between the aperture region and the non-aperture region is small enough to be discernible to the naked eye during the actual display of the aperture region and the non-aperture region.
After the compensation value is calculated, the method may further include programming the compensation value in the screen to be compensated for being read by the terminal device and for screen display according to the compensation value.
As can be seen from the above, the method for determining compensation value for the local display region according to the present embodiment is applied to a terminal device equipped with a screen to be compensated. A screen to be compensated is turned on, and the screen to be compensated includes an aperture region and a non-aperture region. A first display data of the aperture region and a second display data of the non-aperture region when the screen to be compensated is turned on are obtained. Based on the first display data and the second display data, display ratio between the aperture region and the non-aperture region is determined. Based on the display ratio, a compensation value for performing display compensation on the aperture region is calculated. The compensation value for performing the display compensation on the aperture region is calculated, so that the aperture region may be used to display an image after compensated according to the compensation value during display of the aperture region, thereby reducing the display ratio between the aperture region and the non-aperture region, and improving the display effect.
The present disclosure further provides a screen display method applied to a terminal device. Referring to
At Step S201: when a screen of the terminal device is initialized, a compensation value for compensating for display of an aperture region in the screen is obtained.
When the terminal device is powered on, the terminal device needs to be initialized, and the compensation for display of the aperture region may be performed during the initialization process, to compensate for the display difference of the aperture region. In the present embodiment, the definition of the “aperture region” is the same as the definition of the aperture region 101 in the foregoing embodiments, and details are not described herein. Reference may be made to the related description of the foregoing embodiments.
Specifically, the compensation value may be calibrated before the terminal screen is shipped, and programmed in the screen of the terminal device.
In the present embodiment, a method for calculating the compensation value may include: turning on a screen to be compensated; obtaining a display data of the aperture region and a display data of the non-aperture region in the screen of the terminal device; determining display ratio between the aperture region and the non-aperture region based on the display data of the aperture region and the display data of the non-aperture region; and calculating a compensation value for performing display compensation on the aperture region, based on the display ratio between the aperture region and the non-aperture region. The definition of the “non-aperture region” is the same as the definition of the non-aperture region in the foregoing embodiments, and details are not described herein. Reference may be made to the related description of the foregoing embodiments.
Further, the obtaining of the display data of the aperture region and the display data of the non-aperture region in the screen of the terminal device may include: obtaining image data displayed in the aperture region and image data displayed in the non-aperture region, the image data being represented in the RGB color space, that is, represented by primary color components of red, green, or blue; and converting the image data in the RGB color space to display data in the Lxy color space or the Luv color space. Here, the display data in the Lxy color space includes luminance L and chromaticity coordinates (x, y).
Further, the calculating of the compensation value for performing display compensation on the aperture region based on the display ratio between the aperture region and the non-aperture region may include: calculating a ratio in the luminance L of the aperture region and the non-aperture region, and ratios in x value and y value in the chromaticity coordinates (x, y), respectively. If the ratios are larger, a luminance compensation value a, and a first chromaticity compensation value b for the x value and a second chromaticity compensation value c for the y value in the chromaticity coordinates (x, y) are obtained from the luminance L and the chromaticity coordinates (x, y).
The luminance compensation value a is a compensation value for the red component in the displayed image data, the first chromaticity compensation value b is a compensation value for the green component in the displayed image data, and the second chromaticity compensation value c is a compensation value for the blue component in the displayed image data.
At Step S202, current display data of the aperture region is obtained.
The current display data of the aperture region in Step S202 is image data in the RGB color space, i.e., represented by three primary color components of red, green, or blue.
At Step S203, display compensation is performed on the current display data of the aperture region according to the compensation value, to perform screen display.
For example, if the current display data of the aperture region is (R0, G0, BO) and the compensation values are a, b, c, the actual display data is (aR0, bG0, cBO).
In view of the above, the screen display method according to the present embodiment is applied to a terminal device. When a screen of the terminal device is initialized, a compensation value for compensating for display of an aperture region in the screen is obtained, current display data of the aperture region is obtained, and display compensation is performed on the current display data of the aperture region according to the compensation value, to perform screen display. Therefore, the display data of the aperture region is compensated to reduce the display difference between the aperture region and the non-aperture region, thereby improving the overall display effect.
In the method according to the above embodiment, the present embodiment will be further described with respect to the apparatus for determining compensation value for local display region, which may be embodied as a separate entity or may be integrated in a terminal device.
