Detailed Description

In order to facilitate the clear description of the technical solutions of the embodiments of the present application, the following simply describes some terms and techniques involved in the embodiments of the present application:

1. Smear phenomenon: when a moving object exists in an image displayed on a display screen (screen), the phenomenon that the moving object may generate a smear on the display screen is referred to, so that the viewing experience of a user is reduced.

It can be understood that in the case of low indoor brightness, the brightness of the mobile phone picture automatically dimmes to darkest. If the screen is slid to switch the picture; due to the hysteresis effect of the OLED, the first frame is dragged with lower brightness and accompanied with smear, and meanwhile, PWM dimming configuration of the device can cause smear phenomenon to aggravate the problems of glare and dizziness caused by long-time watching of a screen by eyes of a person, so that user experience is affected

2. Color accuracy (just noticeable color difference, JNCD) refers to the minimum unit in which the human eye can distinguish between color changes. It can be appreciated that the smaller the JNCD value, the better the effect of reducing the true color of the screen.

3. Gray scale: the brightness change between the brightest and darkest is divided into several portions. So as to facilitate the control of the screen brightness corresponding to the signal input. Each digital image is composed of a number of dots, also known as pixels (pixels), which typically each display a number of different colors, consisting of three sub-pixels, red, green, and blue (RGB). The light source behind each sub-pixel may exhibit a different brightness level. While gray scale represents the hierarchical level of different brightness from darkest to brightest. The more such intermediate levels, the finer the picture effect that can be presented.

Taking the 8bit panel as an example, it can represent the 8 th power of 2, which is equal to 256 brightness levels, we call 256 gray levels. Each pixel on the LCD screen is composed of red, green and blue with different brightness levels, and finally different color points are formed. That is, the color change of each point on the screen is actually brought about by the gray-scale change of the three RGB sub-pixels constituting the point.

It will be appreciated that the smear phenomenon may be more severe when the terminal device is used in a dark environment of the user.

Currently, smear color cast tests are used to determine the severity of smear by comparing with a visual inspection. The method can intuitively observe the smear phenomenon and the color cast phenomenon, but the picture is always in the degree that the dynamic blurring does not have standard judgment color cast in the dragging process, and the smear degree cannot be accurately and effectively judged. Moreover, due to the fact that the human eyes have different sensitivity to different colors in a dark environment, the original standard cannot cover all color cast problems.

In addition, when a target area of a next frame is brightly rendered in advance at the time of dragging according to the brightness of a pixel to reduce a smear phenomenon, an overcompensation problem may occur, so that power consumption of a terminal device increases.

In view of this, an embodiment of the present application provides a display method, which determines a smear degree according to brightness of a test object before and after sliding, and further determines a corresponding smear compensation parameter to compensate for display on a display screen. Therefore, interference of human factors is reduced, the smear degree is accurately and objectively determined, the accuracy of subsequent smear compensation is further improved, the problem of overcompensation is solved, the display effect of a display screen is improved, and the user experience is improved. In addition, the terminal equipment can evaluate and compensate the smear degree without using an additional camera for smear evaluation.

Illustratively, a first image of the test object before movement is displayed, and then a second image of the test object as it moves is displayed. In other embodiments, the terminal device displays the first image and the second image simultaneously. The left region of the terminal device displays a first image before movement, and the right region displays a second image of the test object when movement is performed.

For example, the terminal device may control the test object to move according to a preset moving speed and a preset direction. The preset moving speed may be set according to actual situations or experience, and the embodiment of the present application is not limited herein with respect to a specific value of the preset moving speed. The preset direction may be up, down, left, right, etc., which is not particularly limited in the embodiment of the present application.

In other embodiments, the terminal device may control the movement of the test object based on a sliding operation of the user. The moving speed and moving direction of the test object are related to the sliding operation of the user.

S402, the terminal equipment respectively processes the pixel parameters corresponding to the first image and the pixel parameters corresponding to the second image to obtain a first color coordinate and a second color coordinate.

The pixel parameter may be a luminance corresponding to a pixel, a driving voltage applied to the pixel, or the like, and is not limited herein.

The terminal device may process pixel parameters corresponding to a partial region in the image. It can be understood that the terminal device can determine the monochrome gray scale of red, green and blue (R/G/B) according to the brightness corresponding to the pixel or the applied driving voltage, and further calculate the color coordinates based on the conversion relationship between the gray scale and the color coordinates.

For ease of understanding, the process of converting pixel to color coordinates is described below in conjunction with fig. 5.

It will be appreciated that the image displayed by the display screen is composed of pixels, each of which may take on a number of different colours, which are composed of three sub-pixels, red, green and blue (RGB). Illustratively, the pixel corresponding to the test object may be as shown as a in fig. 5.

The light source behind each sub-pixel may exhibit a different brightness level. By way of example, the different brightnesses from darkest to brightest can be divided into 256 brightness levels (shown as b in fig. 5).

The terminal device may obtain the color coordinates (shown as c in fig. 5) corresponding to the test object in the chromaticity space according to the brightness levels of the three sub-pixels of red, green and blue (RGB).

S403, the terminal equipment determines a first smear compensation parameter based on the first gray level difference and a corresponding relation, wherein the corresponding relation is the relation between the smear compensation parameter and the gray level difference.

The gray scale difference refers to the difference between the color coordinates. The first gray scale difference is the difference between the first color coordinate and the second color coordinate.

It will be appreciated that the extent of smear of the terminal device is related to the brightness of the display screen, the moving speed of the object, etc. For example, when the moving speed (sliding speed) of the terminal device is fast and slow, the user cannot see or can see a very slight smear color cast phenomenon; when slid at a certain suitable speed, the user can see a significant color cast problem.

S404, the terminal equipment displays the image based on the first smear compensation parameter.

The first smear compensation parameter adjusts the display parameter of a display screen corresponding to the terminal equipment when the terminal equipment is at the first brightness and the object moves at the first moving speed; and when the terminal equipment is at the first brightness and the object moves at the first moving speed, displaying the image based on the adjusted display parameters.

The object may be any object, may be a list, or may be a picture, a text, or the like displayed in a moving manner, which is not limited herein.

The first smear compensation parameter may be used to perform current adjustment of a light emitting element, driving time adjustment of the light emitting element, driving voltage adjustment, and the like in the display screen.

It will be appreciated that the terminal device may determine smear compensation parameters at a plurality of brightness, a plurality of movement speeds. The specific flow may refer to S401 to S403, which are not described herein.

And the terminal equipment obtains smear compensation parameters corresponding to the first brightness and the second moving speed under the first brightness and the second moving speed.

Taking the smear compensation parameter under 7 brightness as an example, the 7 brightness may be 2 nit (nit), 4 nit, 10 nit, 20 nit, 50 nit, 90 nit, respectively. The embodiment of the application is not limited to the value of the brightness, the interval between the brightness and the like.

In some embodiments, the terminal device may determine and store N smear compensation parameter values corresponding to the movement speeds at each brightness. N may be 100 or any number, and is not limited herein. In this way, the terminal device can adjust the smear compensation parameter based on different moving speeds, thereby reducing the smear phenomenon.

The N moving speeds may be uniformly divided speed intervals. Illustratively, the speed interval is 0 pixels per millisecond to 100 pixels per millisecond, N is 5, and the N moving speeds are 20 pixels per millisecond, 40 pixels per millisecond, 60 pixels per millisecond, 80 pixels per millisecond, 100 pixels per millisecond, respectively.

The N moving speeds may also be non-uniform division of the speed interval based on terminal device usage. Illustratively, the speed interval is 0 pixels per millisecond to 100 pixels per millisecond, N is 5, and the N moving speeds are 20 pixels per millisecond, 30 pixels per millisecond, 40 pixels per millisecond, 70 pixels per millisecond, 100 pixels per millisecond, respectively. In the embodiment of the application, the value and the number of the moving speeds of the terminal equipment are not particularly limited under the same brightness.

The N moving speeds may also take values of moving speeds (sliding speeds) based on the use situation of the terminal device. For example, the movement speed range frequently used by the user corresponds to more movement speed values.

In conclusion, the terminal equipment can accurately evaluate the smear degree, and carry out smear compensation aiming at smear phenomena of different degrees, so that the smear phenomena of the terminal equipment are reduced, and the user experience is improved. The pertinence is strong, and the accuracy is high. In addition, the over-compensation problem can be reduced, and the power consumption of the terminal equipment can be reduced. The electric signal is converted into readable and measurable color coordinates by capturing the gray scale of the regional pixels of the test object, and the evaluation and compensation of the smear degree can be realized without the participation of other equipment.

It is understood that the terminal device may perform the above-described S401-S403 only when the smear calibration is first turned on. After the terminal device starts the smear calibration, S401-S403 may also be executed periodically. The period duration is three months or one month, and the period duration of the smear calibration is not limited in the embodiment of the application.

The subsequent smear calibration process is similar to the process shown in fig. 4, and will not be described again here.

The smear calibration process is as follows: the terminal equipment displays a fifth image, wherein the fifth image is an image displayed by the terminal equipment under the first brightness; the terminal equipment displays a sixth image, wherein the sixth image is displayed when the terminal equipment moves at the first brightness and the first moving speed of the test object; the terminal equipment processes the pixel parameters corresponding to the fifth image and the pixel parameters corresponding to the sixth image to obtain fifth color coordinates corresponding to the fifth image and sixth color coordinates corresponding to the sixth image; the terminal equipment determines a third smear compensation parameter based on a third gray scale difference and a corresponding relation, wherein the third gray scale difference is related to a fifth color coordinate and a sixth color coordinate.

Therefore, the smear compensation parameters can be adjusted according to the use condition of the terminal equipment, the color cast fluctuation caused by the light-emitting efficiency attenuation of the display screen light-emitting material is reduced, and the user experience is improved.

On the basis of the above embodiment, the terminal device also calculates the execution result S405.

And S405, the terminal equipment obtains obvious color difference values (just noticeable color difference, JNCD values) of the image according to the first color coordinates and the second color coordinates.

In the embodiment of the application, when JNCD values are larger than or equal to a preset threshold, the terminal equipment adjusts the smear compensation parameter based on the gray level difference and the corresponding relation. And when JNCD values are smaller than a preset threshold value, the terminal equipment does not adjust the smear compensation parameter.

In this way, the frequency of the terminal device adjusting the smear compensation parameter can be reduced.

In a possible implementation manner, the terminal device may calculate a distance Δuv between the first color coordinate and the second color coordinate, and calculate JNCD according to the distance Δuv between the color coordinates. In some embodiments JNCD meets Δuv/0.004.

For example, as shown by d in fig. 5, two color coordinates correspond to the coordinate point 1 and the coordinate point 2, respectively, and the distance between the coordinate point 1 and the coordinate point 2 may be the distance between the color coordinate 1 and the color coordinate 2 of the line segment 501.

In this way, the amount of computation of the terminal device can be reduced.

In some embodiments, the terminal device further performs S406 before performing S404.

S406, the terminal equipment acquires the brightness of the display screen.

In some embodiments, the terminal device obtains backlight and ambient light parameters of the display screen to determine brightness of the display screen.

When the brightness of the display screen is less than or equal to the first threshold, the terminal device performs S404. And when the brightness of the display screen is larger than the first threshold value, the terminal equipment does not carry out smear compensation.

It will be appreciated that the bias, smear and color bias are related to the brightness of the terminal device. The lower the brightness displayed by the terminal device, the heavier the degree of bias. When the brightness of the display of the terminal equipment is higher, the degree of bias, smear and color cast is lower.

In this way, the terminal equipment performs smear compensation in a scene with low brightness, so that the smear phenomenon of the terminal equipment can be reduced, and the problem of image color cast caused by the luminous efficiency difference of the display device can be reduced. In a scene with high brightness, the terminal equipment does not carry out smear compensation, so that the calculated amount displayed by the terminal equipment can be reduced.

On the basis of the above embodiment, the terminal device also acquires the moving speed of each object in the image before displaying the image. The terminal equipment respectively determines the smear compensation parameters of each object based on the brightness of the display screen and the moving speed of each object, and further displays images based on the smear compensation parameters of each object. It will be appreciated that the terminal device may default to initiate automatic calibration of the smear compensation parameter. Automatic calibration of smear compensation parameters may also be defaulted not to be turned on.

The interface shown as e in fig. 6 displays a test object in a first position, and the interface shown as f in fig. 6 displays a test object in a second position, the first position and the second position being different. The test object may be a picture, a text, or a combination of a picture and a text, which is not limited herein.

In some embodiments, the terminal device may adjust the brightness of the display screen and the moving speed of the test object when performing the smear calibration, so as to perform the smear calibration on the display with different brightness and different moving speed.

In some embodiments, the terminal device performs the smear calibration every time the smear calibration function is turned on. In some embodiments, the terminal device may further perform smear calibration when receiving an operation for indicating smear calibration. For example, a click operation by the user to turn on the smear calibration 604 is received, or a voice operation of "perform smear calibration" is received.

In other embodiments, the terminal device performs the smear calibration when the smear calibration function is first turned on. The smear calibration is performed again after a while. The period of time may be one month or three months, which is not limited in the embodiment of the present application.

In a possible implementation, the terminal device performs smear calibration when the device is idle. The device may be idle, when no foreground application is running, device dormant, etc. In this way, the disturbance to the user can be reduced.

In other embodiments, the terminal device is provided with an application for smear calibration. Smear calibration is performed by this application.
