Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant application and are not limiting of the application. It should be noted that, for the convenience of description, only the parts related to the related applications are shown in the drawings.
The embodiment of the application provides a display method which is applied to a terminal. The terminal may be an electronic device such as a mobile phone and a tablet computer, and the specific terminal is not limited in the embodiment of the present application.
It should be noted that, in the embodiments of the present application, the terminal includes a display screen, and the display screen includes a light-transmitting display area and a normal display area. The brightness decay speed of the light-transmitting display area is higher than that of a normal display area.
It will be appreciated that in embodiments of the present application, the display screen may be divided into two regions, a transmissive display region and a normal display region. The light-transmitting display area is actually a display area corresponding to the front camera. The front camera is arranged below the transparent display area, the number of pixels arranged in the transparent display area is small, and the pixel density is low, so that incident light penetrating through gaps among the pixels in the transparent display area can be received by the front camera to form images. Since the transparent display area has fewer pixels and low density, and the normal display area has more pixels and high density, the brightness attenuation speed is higher than that of the normal display area, as shown in fig. 1, which is a contrast graph of brightness attenuation of displaying a pure white picture under the same brightness of the normal display area and the transparent display area.
Fig. 2 is a luminance decay curve of an exemplary normal display area according to an embodiment of the present disclosure. Fig. 3 is a luminance decay curve of an exemplary light-transmissive display region according to an embodiment of the present disclosure. As shown in fig. 2 and 3, 10 display screens are taken as test objects, that is, 10 series in the corresponding graph and fig. 3, corresponding brightness attenuation curves can be respectively determined, wherein the brightness attenuation speeds of the transparent display area and the normal display area are not consistent, but it can be seen from the comparison of multiple sets of data that the brightness attenuation curves are relatively stable in the transparent display area or the normal display area. I.e. uniformity and reliability of the display screen is guaranteed. This is the physical basis for correcting for brightness decay.
Based on the description of the display screen, the display method will be described in detail below.
Fig. 4 is a schematic flowchart of a display method according to an embodiment of the present application. As shown in fig. 4, in the embodiment of the present application, the display method mainly includes the following steps:
s101, converting first use time of the light-transmitting display area under standard brightness by using the acquired first use information of the light-transmitting display area, and converting second use time of the normal display area under the standard brightness by using the acquired second use information of the normal display area.
In the embodiment of the application, the terminal may convert the first use duration of the light-transmitting display area under the standard brightness by using the acquired first use information of the light-transmitting display area, and convert the second use duration of the normal display area under the standard brightness by using the acquired second use information of the normal display area.
It is understood that, in the embodiment of the present application, the standard brightness may be a preset brightness, and specifically may be the highest brightness that can be achieved by the display screen. When a user uses the terminal daily, the transparent display area is not always under the standard brightness, and may be under various brightness conditions, so that the historical use duration under different brightness conditions needs to be converted to obtain the use duration under the standard brightness.
Specifically, in an embodiment of the present application, before the terminal converts the first usage duration of the light-transmitting display area under the standard brightness by using the acquired first usage information of the light-transmitting display area, the method includes: acquiring used low gray scale brightness of a light-transmitting display area, and determining each acquired low gray scale brightness as a first low gray scale brightness to obtain at least one first low gray scale brightness; acquiring the use time of each first low gray scale brightness in at least one first low gray scale brightness of the light-transmitting display area to obtain at least one first historical time; at least one first low gray scale luminance and at least one first history duration are determined as the first usage information.
It should be noted that, in the embodiment of the present application, the terminal may continuously monitor the low gray-scale luminance of the transparent display area, so as to be able to obtain each used low gray-scale luminance of the transparent display screen, and determine each used low gray-scale luminance as a first low gray-scale luminance. In addition, the terminal can continuously count the use duration of different low gray scale brightness in the process of historical use of the light-transmitting display area, and each use duration is determined as a first historical duration, so that at least one first historical duration is obtained.
Specifically, in an embodiment of the present application, the method for converting, by a terminal, a first usage duration of a light-transmitting display area under standard brightness by using acquired first usage information of the light-transmitting display area includes: acquiring at least one first time length conversion parameter corresponding to at least one first low gray scale brightness; converting each time length in the at least one first historical time length into a first standard time length by using a corresponding parameter in the at least one first time length conversion parameter to obtain at least one first standard time length; the sum of the at least one first standard time duration is determined as the first usage time duration.
It should be noted that, in the embodiment of the present application, time length conversion parameters corresponding to different low gray-scale luminances are stored in the terminal. Therefore, the terminal can directly acquire the at least one first time length conversion parameter. The specific time length conversion parameter is not limited in the embodiments of the present application.
It should be noted that, in the embodiment of the present application, the terminal may multiply each duration in the at least one first historical duration by a corresponding parameter in the at least one duration conversion parameter to obtain a corresponding standard duration, and then add all the standard durations to obtain the first usage duration, that is, convert the usage duration of the transparent display screen at the standard brightness.
Specifically, in the embodiment of the present application, in a case that the transparent display area has used n low gray-scale luminances, n is a natural number greater than or equal to 1, and the terminal may convert the first usage duration of the transparent display area under the standard luminance by using formula (1), where the specific formula is as follows:
wherein, TStandard of meritFor a first duration of use, T, of the light-transmissive display region at standard brightnessiThe duration of the light-transmitting display area under the ith low gray scale brightness in the n low gray scale brightness, and K (i) is a duration conversion parameter corresponding to the ith low gray scale brightness.
Specifically, in an embodiment of the present application, before the terminal converts the second usage duration of the normal display area under the standard brightness by using the obtained second usage information of the normal display area, the method includes: acquiring used low gray scale brightness of a normal display area, and determining each acquired low gray scale brightness as a second low gray scale brightness to obtain at least one second low gray scale brightness; obtaining the use time of each second low-gray-scale brightness in at least one second low-gray-scale brightness of the normal display area to obtain at least one second historical time; and determining at least one second low gray scale brightness and at least one second historical duration as second usage information.
Specifically, in an embodiment of the present application, the converting, by the terminal, the second use duration of the normal display area under the standard brightness by using the obtained second use information of the normal display area includes: acquiring at least one second duration conversion parameter corresponding to at least one second low gray-scale brightness; converting each time length in the at least one second historical time length into a second standard time length by using a corresponding parameter in the at least one second time length conversion parameter to obtain at least one second standard time length; the sum of the at least one second standard time duration is determined as the second usage time duration.
It can be understood that, in the embodiment of the present application, the terminal uses the second usage information of the normal display area to convert the second usage duration of the normal display area under the standard brightness, which is completely the same as the way of using the first usage information of the transparent display area to convert the second usage duration of the transparent display area under the standard brightness, and is not described herein again.
S102, determining the brightness difference between the light-transmitting display area and the normal display area based on the first using time length and the second using time length.
In the embodiment of the application, after the terminal obtains the first using time length and the second using time length, the brightness difference between the light-transmitting display area and the normal display area is determined based on the first using time length and the second using time length.
Specifically, in an embodiment of the present application, the determining, by the terminal, the brightness difference between the transparent display area and the normal display area based on the first duration of use and the second duration of use includes: acquiring first brightness attenuation information corresponding to the first use duration and second brightness attenuation information corresponding to the second use duration; and determining the brightness difference according to the first brightness attenuation information and the second brightness attenuation information.
It should be noted that, in the embodiment of the present application, for the transparent display area and the normal display area, luminance attenuation information corresponding to different use durations of the transparent display area and the normal display area under standard luminance is counted in advance, so that after the terminal obtains the first use duration and the second use duration, the first luminance attenuation information and the second luminance attenuation information can be obtained.
And S103, under the condition that the brightness difference exceeds a preset difference threshold, performing brightness compensation processing on an image area corresponding to a light-transmitting display area in the target image based on the brightness difference to obtain a compensation image.
In the embodiment of the application, after the terminal determines the brightness difference, under the condition that the brightness difference exceeds a preset difference threshold, the brightness compensation processing is performed on an image area corresponding to a light-transmitting display area in the target image based on the brightness difference, so that a compensation image is obtained.
In the embodiment of the present application, the target image is an image that needs to be displayed on the display screen. The specific target image may be determined according to actual requirements, and the embodiment of the present application is not limited.
Specifically, in an embodiment of the present application, the method for performing brightness compensation processing on an image area corresponding to a transparent display area in a target image by a terminal based on a brightness difference to obtain a compensated image includes: acquiring preset correction parameters corresponding to the brightness difference; loading a preset correction parameter to a preset skin function to obtain a loaded skin function; and carrying out skinning processing on the image area by using the loaded skinning function to obtain a compensation image.
It can be understood that, in the embodiment of the present application, before the terminal controls the display screen to display the original image or video data, that is, the target image, a skinning function covering preset correction parameters is added to the image corresponding to the transparent display area in the target image, and after the skinning function covers, the information of each pixel point in the image area has been modified and adapted.
FIG. 5 is an exemplary compensated image after skinning according to an embodiment of the present disclosure. As shown in fig. 5, on an original target image, the terminal performs a skinning function on an image area corresponding to a fillet of a screen in a display screen and a display area corresponding to a camera under the screen, that is, a transparent display area, so as to obtain a compensated image.
And S104, controlling the display screen to display the compensation image.
In the embodiment of the application, after the terminal obtains the compensation image, the terminal can control the display screen to display the compensation image.
It can be understood that, in the embodiment of the present application, the terminal controls the display screen to display the compensation image, and since the compensation image is obtained by performing a skinning function on an image area corresponding to the transparent display area by using the target image, the compensation image displayed on the display screen will have an effect of no brightness difference, that is, visually, a user can see that the brightness of each part of the compensation image displayed in the transparent display area and the normal display area is consistent.
It can be understood that, in the embodiment of the present application, the terminal may control the driving circuit to correspondingly supply power to different pixels in the display screen according to the compensation image, so as to display the compensation image on the display screen. The compensation image is identical to the image content actually represented by the target image, except that the brightness effect displayed in accordance with the compensation image is consistent between the transparent display area and the normal display area.
It should be noted that, in the embodiment of the present application, in step S102, after the terminal determines the brightness difference between the transparent display area and the normal display area, the brightness difference may not exceed the preset difference threshold, and therefore, after the terminal determines the brightness difference between the transparent display area and the normal display area based on the first duration of use and the second duration of use, the method further includes: and controlling the display screen to display the target image under the condition that the brightness difference does not exceed the preset difference threshold value.
It can be understood that, in the embodiment of the present application, since the luminance decay rate of the display screen itself is relatively slow, the display correction of the light-transmitting display area does not need to be performed in real time, and the correction is performed when the luminance difference is selected to a certain extent.
The embodiment of the application provides a display method, which is applied to a terminal, wherein the terminal comprises a display screen, the display screen comprises a light-transmitting display area and a normal display area, the brightness attenuation speed of the light-transmitting display area is higher than that of the normal display area, and the method comprises the following steps: converting the first use time of the light-transmitting display area under the standard brightness by using the acquired first use information of the light-transmitting display area, and converting the second use time of the normal display area under the standard brightness by using the acquired second use information of the normal display area; determining the brightness difference between the light-transmitting display area and the normal display area based on the first use duration and the second use duration; under the condition that the brightness difference exceeds a preset difference threshold value, performing brightness compensation processing on an image area corresponding to a light-transmitting display area in the target image based on the brightness difference to obtain a compensation image; and controlling the display screen to display the compensation image.
