Meanwhile as function of the user to liquid crystal display is put forward higher requirements, existing liquid crystal display can be for User carries out the switching of different display modes, under specified display pattern, in each pixel of the liquid crystal display of terminal at least The gap of the turnover voltage loaded in two sub-pixels is greater than specified disparity threshold, wherein turnover voltage is for controlling liquid The maximum drive voltage of crystalline substance overturning, that is to say that turnover voltage is the defined maximum rated voltage that can be loaded on liquid crystal.? Under this specified display pattern, if the picture that liquid crystal display is shown is black and white interface, due at least two son in each pixel The gap of the turnover voltage loaded in pixel is larger, therefore in liquid crystal overturning, the reversal rate of the sub-pixel in pixel is different, Lead to the trailing phenomenon for black and white interface occur.For example, the overturning loaded on the blue subpixels of display screen is electric under eyeshield mode Pressure is usually less than the turnover voltage loaded in red sub-pixel and green sub-pixels.Due to the turnover voltage of blue subpixels load It is smaller, so that its liquid crystal reversal rate is delayed, black and white interface is caused to occur showing for picture lag in liquid crystal display screen display As that is to say trailing phenomenon.
The embodiment of the present disclosure provides a kind of interface display method, can solve the above problem, as shown in Figure 1, this method is answered For terminal, this method comprises:
Step 101 is specified under display pattern when terminal is in, and when terminal display black and white interface, judges black and white interface Whether content can change, wherein under specified display pattern, at least two in each pixel of the liquid crystal display of terminal The gap of the turnover voltage loaded on sub-pixel is greater than specified disparity threshold, and turnover voltage is used to control the maximum of liquid crystal overturning Driving voltage.
Step 102, when the content for determining black and white interface can change, determine that content can change in black and white interface Target area.
Step 103, in the content change of target area, adjust in target area at least one sub-pixel in each pixel The turnover voltage of upper load, so that the difference of the turnover voltage loaded on any two sub-pixel in target area in each pixel Away from no more than disparity threshold.
In conclusion the interface display method that the embodiment of the present disclosure provides, is specified under display pattern, and eventually when terminal is in When the display black and white interface of end, determine in the black and white interface content can changed target area, the content in the target area When variation, the turnover voltage loaded at least one sub-pixel in each pixel in the target area is adjusted, so that the target area The gap of the turnover voltage loaded on any two sub-pixel in domain in each pixel is not more than disparity threshold, due to target area The gap of the turnover voltage loaded on any two sub-pixel in domain in each pixel is smaller, therefore, in liquid crystal overturning, The reversal rate of sub-pixel in pixel is close, effectively reduces the trailing phenomenon of black and white interface appearance.
The embodiment of the present disclosure provides a kind of interface display method, and this method can be applied to the end with liquid crystal display End, the terminal can also have other assemblies, as shown in Fig. 2, the terminal 20 includes liquid crystal display 201, panel driving chip 202 And its internal buffer 2021 and application processor (English: ApplicationProcessor；Referred to as: AP) 203, wherein Liquid crystal display 201 is for showing image, and panel driving chip 202 is for driving liquid crystal display to show image, using processing Data of the device 203 for the application program (for example, game application or Web page application program etc.) on processing terminal.Certainly, Fig. 2 is a kind of optional realization structure of the terminal, and the disclosure is not defined the structure of terminal.As shown in figure 3, the boundary Plane display method includes:
Step 301 is specified under display pattern when terminal is in, and whether detection terminal shows black and white interface.
Wherein, black and white interface can be text interface and/or graphic interface, can be the application program installed in terminal In interface.
As previously mentioned, under specified display pattern, if the interface that liquid crystal display is shown is black and white interface, due to each picture The gap of the turnover voltage loaded at least two sub-pixels in element is greater than specified disparity threshold, exemplary, the disparity threshold Value range can be 0.5V-1V, in liquid crystal overturning, the reversal rate of the sub-pixel in each pixel is different, black and white circle Face will appear the phenomenon that picture lag during display, therefore, when the current display pattern of liquid crystal display is specified display When mode, whether the display interface that can detecte terminal is black and white interface, to be performed corresponding processing for the black and white interface, from And the picture hysteresis occurred when picture being avoided to show.
Fig. 2 is referred to, terminal 20 generally comprises liquid crystal display 201, panel driving chip 202 and application processor 203, The panel driving chip 202 includes buffer 2021 again, in general, the buffer is for caching the next of the picture frame currently shown The data of a picture frame that is to say the data for the picture frame that buffer will be shown.In the embodiments of the present disclosure, the data It can be pixel value (such as rgb value) or gray value.
Since the picture frame in terminal continuously displays, there is usually no jumps for the display of image, therefore, can detecte Next picture frame of the picture frame currently shown, if next picture frame corresponds to black and white interface, it is determined that currently show Picture frame corresponds to black and white interface.Due to being cached with the data of next picture frame of the picture frame currently shown in buffer, then Terminal can detect whether display interface is black and white interface based on the data cached in buffer, and the disclosure is examined with following two It is illustrated for survey mode:
The first detection mode, terminal detect the display interface of terminal by comparing the data of adjacent two field pictures frame It whether is black and white interface.Optionally, which is the picture frame currently shown and its next picture frame. Which includes:
Step A1, the data of the picture frame cached in buffer are detected.
Terminal can read the data of the picture frame cached in its buffer by panel driving chip, which can Think pixel value or gray value.
Step A2, when the data of the picture frame of caching are made of the first data and the second data, determine that terminal shows black and white The difference of interface, the first data and white corresponding data is less than the first difference threshold, the difference of the second data and black corresponding data Value is less than the second difference threshold.
Whether terminal close to black corresponding data or white corresponding data can determine end based on the data in picture frame Whether end shows black and white interface.For example, terminal can be respectively by the data of the picture frame cached in buffer number corresponding with white Accordingly and black corresponding data makes the difference, when the difference of a certain data x1 and white corresponding data is less than the first difference threshold, by this A certain data x1 is determined as the first data；When the difference of a certain data x2 and black corresponding data is less than the second difference threshold, general The a certain data x2 is determined as the second data.It wherein, is accordingly pixel when white corresponding data is that pixel is integrally displayed in white Brightness value is also labeled as RGB for example, white corresponding data is R=255, G=255 and B=255 when the data are pixel value (255,255,255)；When the data are the gray value of pixel, white corresponding data is 255；Black corresponding data is that pixel is whole When showing black, the brightness value of corresponding pixel.For example, the data be pixel value when, black corresponding data be R=0, G=0 and B=0 is also labeled as RGB (0,0,0)；When the data are the gray value of pixel, black corresponding data is 0.First difference threshold It can be pre-set fixed threshold with the second difference threshold, be also possible to the variable thresholding being dynamically determined.Exemplary, this The value range of one difference threshold and the second difference threshold can be 1-5.First difference threshold and the second difference threshold can phases It is same to can also be different.
It is exemplary, it is assumed that the first difference threshold and the second difference threshold are 2, white corresponding data are as follows: gray value is 255, black corresponding data are as follows: gray value 0, a certain data x1 is gray value 254, due to the gray value of a certain data x1 254 with the difference 1 of the gray value 255 of white corresponding data less than the first difference threshold 2, then a certain data x1 is determined as the One data；A certain data x2 is gray value 0, due to a certain data x, 2 gray value 0 and the gray value 0 of black corresponding data Difference 0 less than the second difference threshold 2, then a certain data x2 is determined as the second data.
When terminal display black and white screen, then the process of subsequent step 302 to step 305 is executed.
Step A3, when the data of the picture frame of buffer include third data, determine that terminal does not show that black and white is drawn Face, third data are the data in addition to the first data and the second data.
It is exemplary, it is assumed that in the embodiment of the present disclosure, the first difference threshold and the second difference threshold are 2, the corresponding number of white According to being 255, black corresponding data is 0, and a certain data x3 is gray value 240, then a certain data x3 has both been not belonging to the first number According to being also not belonging to the second data, belong to third data.
When terminal does not show black and white screen, then without executing the process of subsequent step 302 to step 305.
It should be noted that buffer can also cache at least two adjacent picture frames, two adjacent picture frames It can be the picture frame and its next picture frame that currently show, next picture frame of the picture frame also currently shown, with Next picture frame under and its, terminal can be come the display interface for detecting terminal by comparing the data of adjacent two field pictures frame No is black and white interface.Its process can refer to the first above-mentioned detection mode, and the disclosure repeats no more this.
Second of detection mode, terminal establish histogram based on the data cached in buffer to detect display circle of terminal Whether face is black and white interface.Which includes:
Step B1, the data based on the picture frame cached in buffer generate histogram.
First axle in the histogram indicates that different colours corresponding data, the second axis indicate point of different colours corresponding data Cloth situation.Wherein, first axle is horizontal axis, and the second axis is the longitudinal axis；Alternatively, first axle is the longitudinal axis, the second axis is horizontal axis.The histogram The distribution situation of different colours corresponding data for reflecting in the picture frame cached in buffer.It is exemplary, above-mentioned difference face Color corresponding data may include white corresponding data and/or black corresponding data.The data can be pixel value or gray value.
Step B2, the distribution situation based on black corresponding data in the histogram and white corresponding data, detection terminal are No display black and white interface.
In implementation process, above-mentioned steps B2 can be there are many optional implementation, and the embodiment of the present disclosure is with following two It is illustrated for the achievable mode of kind:
The first optional implementation, when there was only black corresponding data and white corresponding data distribution in histogram, really Determine terminal and shows black and white interface.When removing black corresponding data and white corresponding data in histogram, there are also other color corresponding datas Distribution, determines that terminal does not show black and white interface.
For example, buffer is stored with the gray value of the pixel in picture frame.Second axis of the histogram in step B1 indicates Pixel gray value distribution situation, can be reflected by the corresponding number of pixels of gray value.As shown in figure 4, horizontal axis Indicate that gray value, the longitudinal axis indicate the number of pixels of corresponding grey scale value, it is assumed that the liquid crystal display there are 5,000,000 pixels, wherein ash Angle value is pixel totally 350 ten thousand of 255, gray value is pixel totally 150 ten thousand of 0, then illustrates that the liquid crystal display is shown The image that pixel is shown is non-black i.e. white, it is determined that terminal shows black and white interface.
Second of optional implementation, when the distribution accounting of black corresponding data in histogram and white corresponding data it Accounting threshold value is specified with being greater than, determines that terminal shows black and white interface.When black corresponding data in histogram and white corresponding data The sum of distribution accounting no more than specified accounting threshold value, determine that terminal does not show black and white interface.
For example, buffer is stored with the gray value of the pixel in picture frame.Optionally, as shown in figure 4, it is straight in step B1 The distribution situation of gray value represented by second axis of square figure can be reflected by the corresponding number of pixels of gray value.Then base In the summation of the respective pixel number of the statistics with histogram black corresponding data and white corresponding data, by the summation and picture frame The ratio of the total number of middle pixel is determined as the sum of the distribution accounting of black corresponding data and white corresponding data in histogram, when The sum of the distribution accounting is greater than specified accounting threshold value, determines that terminal shows black and white interface.
Optionally, the distribution situation of gray value represented by second axis of the histogram in step B1 can also be by not Reflect with the distribution accounting of gray value.It that is to say the ratio that the second axis indicates that different gray values occur in picture frame.
As shown in figure 5, horizontal axis indicates that gray value, the longitudinal axis indicate the distribution accounting of different gray values, it is assumed that the liquid crystal display Screen has 5,000,000 pixels, and the summation for the pixel that wherein gray value is 255 accounts for the 40.5% of all pixels number, the picture that gray value is 0 The summation of element accounts for the 59% of all pixels number, and the summation of the pixel of other gray values accounts for the 0.5% of all pixels number, it is assumed that accounting Threshold value is 99%, then since the sum of black corresponding data in histogram and the distribution accounting of white corresponding data are 99.5%, really Determine terminal and shows black and white interface.
It should be noted that Fig. 4 and Fig. 5 are the drafting mode of two kinds of schematical histograms, the disclosure is to histogram Drafting mode do not limit.
It is worth noting that terminal can also specially store the data of the picture frame shown certainly, it is then based on the data Determine whether the picture frame currently shown is black and white interface, for example, caching the picture frame currently shown in the buffer of terminal, then Terminal can detect whether display interface is black and white interface, detection side based on the data of the picture frame cached in buffer Two kinds of detection modes that formula can be provided with reference to above-mentioned steps 301 that is to say with the data of the picture frame of buffer to be to work as The data of the picture frame of preceding display, to execute above two detection mode, the embodiment of the present disclosure repeats no more this.
Step 302, when terminal show black and white interface when, judge whether the content at black and white interface can change.
In the first optional implementation, terminal can detecte the figure cached in the buffer of its panel driving chip Whether the data of row corresponding as picture frame of each row of data of frame shown in currently are identical；When the data that there is corresponding row are different When, determine that the content at black and white interface can change；When there is no the data difference of corresponding row, the content at black and white interface is determined It will not change.
It is exemplary, it is assumed that the line n data and the next image frame (figure cached in buffer of the picture frame currently shown As frame) line n data it is as shown in table 1, which is any a line in picture frame, by comparing it is found that the current display Picture frame line n data and next image frame line n data it is different, then the data that there is corresponding row are different, and terminal is true The content for determining black and white interface can change.It is illustrated so that the data being compared is the gray values of pixel as an example in table 1.
Table 1
In second of optional implementation, referring to FIG. 2, since terminal includes application processor, and apply processing Data of the device for the application program on processing terminal, therefore, terminal can be by application processors to directly determining black and white circle Whether the content in face can change.
Step 303, when the content for determining black and white interface can change, determine that content can change in black and white interface Target area.
In the embodiments of the present disclosure, determine target area mode can there are many, the embodiment of the present disclosure is with following a variety of It is illustrated for mode.
Target line data corresponding region in the picture frame cached in buffer is determined as target by the first optional way Region, each target line data are different from the data of the corresponding row of the picture frame currently shown.
As shown in table 1, since the line n data of the picture frame currently shown are different with the line n data of next image frame, Then the corresponding region of line n data of the next image frame can be determined as target area, that is to say, by line n location Domain is determined as target area.
Second of optional way, by the data in the picture frame cached in buffer and data in the picture frame that currently shows Different pixels are determined as target area.
As shown in table 1, since the line n data of the picture frame currently shown are different with the line n data of next image frame, And generate variation be respectively line n data in pixel 1, pixel 4 and pixel 6 gray value, then target area be pixel 1, 6 region of pixel 4 and pixel.
It should be noted that if the optional implementation of the first in above-mentioned steps 302 is taken to determine white and black displays interface Content change, then the comparison result of row data can be corresponded in the first optional implementation based on this, is come direct The first optional way or second optional way for taking above-mentioned steps 303 determine target area.It in this way can quickly really Set the goal region.
The third optional way, referring to FIG. 2, since terminal includes application processor, and application processor is for handling The data of application, therefore, terminal directly can determine that content can changed target in black and white interface by application processor Region.
Step 304, in the content change of target area, adjust in target area at least one sub-pixel in each pixel The turnover voltage of upper load, so that the difference of the turnover voltage loaded on any two sub-pixel in target area in each pixel Away from no more than disparity threshold.
Optionally, when specified display pattern be eyeshield mode when, each pixel include red sub-pixel, green sub-pixels and Blue subpixels, under eyeshield mode, the turnover voltage phase that is loaded in the red sub-pixel and green sub-pixels in each pixel Deng and be the first turnover voltage, the gap of the second turnover voltage and the first turnover voltage that load on blue subpixels is greater than gap Threshold value makes at this point, terminal just will increase the turnover voltage loaded on the blue subpixels of the target area determined by step 304 The gap of the turnover voltage and the first turnover voltage that load on blue subpixels is obtained no more than disparity threshold, so that three sub-pixels The turnover voltage of upper load is identical or almost the same, it is ensured that almost overturning having the same is fast for the liquid crystal in three sub-pixels Degree, to alleviate the trailing phenomenon that black and white interface will appear during display.
It is exemplary, it is assumed that the target area determined by step 303 is the 300th row of liquid crystal display to the 600th row and the In 765 behavior black and white interfaces content can changed target area, under eyeshield mode, preset disparity threshold be 0.4V, The first turnover voltage loaded in red sub-pixel and green sub-pixels is equal and is 5V, and second loaded on blue subpixels turns over Turning voltage is 4.5V, at this point, being greater than 0.4V since the difference of the first turnover voltage 5V and the second turnover voltage 4.5V are 0.5V. In order to avoid trailing phenomenon, terminal just be will increase on the 300th row to the 600th row and the 765th row blue subpixels of liquid crystal display The turnover voltage of load, for example, 4.9V or 5V can be increased to, the turnover voltage loaded on blue subpixels at this time and The difference of one turnover voltage is less than above-mentioned disparity threshold, at this point, liquid crystal display the 300th row to the 600th row and the 765th row is red The liquid crystal turnover voltage loaded on sub-pixels, green sub-pixels and blue subpixels is almost equal, and the reversal rate of liquid crystal is several Identical, alleviating content in black and white interface can the picture lag that occurs during interface display of changed target area Phenomenon, that is, trailing phenomenon.It should be noted that terminal can be different to the increased turnover voltage in different target region, only Guarantee that the gap of the target area the second turnover voltage adjusted and the first turnover voltage is less than disparity threshold, this public affairs Embodiment is opened to be merely illustrative.
Step 305, when the content for determining black and white interface does not change, by the turnover voltage on an at least sub-pixel Restore the turnover voltage to before adjusting.
It after step 304 is performed, can will be in above-mentioned steps 304 when determining that the content at black and white interface does not change The turnover voltage occurred at least one sub-pixel of variation restores the turnover voltage to adjustment, can continue to guarantee in this way Specified display pattern performs effectively.
For example, when specified display pattern is eyeshield mode, since in step 304, terminal has adjusted target area The turnover voltage loaded on blue subpixels, in order to guarantee that the display pattern of liquid crystal display of terminal is continually maintained in eyeshield mould Whether formula, the content that terminal can detect black and white interface continue to change, and can preset the detection frequency of terminal, work as determination When the content at black and white interface does not change, the turnover voltage on the blue subpixels of target area is restored to the overturning to adjustment Voltage.
It is exemplary, it is assumed that the target area determined by step 303 is the 300th row of liquid crystal display to the 600th row and the In 765 behavior black and white interfaces content can changed target area, the liquid crystal display of terminal is this specified in eyeshield mode The first turnover voltage loaded in red sub-pixel and green sub-pixels under display pattern is equal and is 5V, on blue subpixels plus The second turnover voltage carried is 4.5V, preset disparity threshold 0.4V, and the overturning loaded on the blue subpixels after increase is electric Pressure is 4.9V or 5V, at this point, whether terminal can become according to the content at the Data Detection black and white interface cached in buffer To change, it is assumed that detection frequency is 50 each seconds, when terminal detects that the display content at black and white interface does not change, terminal meeting The turnover voltage loaded on the blue subpixels for the target area determined by step 303 is reduced to 4.5V by 4.9V or 5V, So that the display pattern of the liquid crystal display of terminal is continuously maintained at eyeshield mode, the usage experience of user is not influenced.
