Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
In the liquid crystal display, the liquid crystal contains movable ions, and the movable ions can move to the electrode with the opposite polarity under the action of the driving voltage, and can be obtained by the orientation film interface of the liquid crystal over time, so that an internal electric field can exist in the liquid crystal under the condition of not applying external voltage, and the external voltage can not accurately drive the liquid crystal to display a preset gray scale picture, thereby causing the image sticking phenomenon. Accordingly, there is a need to provide a method for improving afterimage to solve the above-mentioned problems.
The method for improving the ghost can be applied to various terminals with liquid crystal displays, the terminals can be but are not limited to various personal computers, notebook computers, smart phones, tablet computers, internet of things equipment and portable wearable equipment, and the internet of things equipment can be smart sound boxes, smart televisions, smart air conditioners, smart vehicle-mounted equipment and the like. The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, and the like.
Referring to fig. 1, fig. 1 shows a flow chart of an embodiment of the method for improving residual image according to the present invention, and the method for improving residual image according to the embodiment of the present invention includes the following steps:
s1, acquiring information Zn of an nth frame of picture and information Zn +1 of an n +1 th frame of picture;
s2, judging whether the information Zn +1 is the same as the information Zn;
and step S31, if the two images are the same, controlling the polarity of the driving voltage to be reversed, and displaying the (n + 1) th frame image.
According to the method for improving the ghost, whether the information Zn +1 of the (n + 1) th frame is the same as the information Zn of the nth frame is judged, if the information Zn +1 of the (n + 1) th frame is the same as the information Zn of the nth frame, the polarity of the driving voltage is controlled to be reversed, and then the (n + 1) th frame is displayed, so that the polarity is timely changed when the same frame is continuously displayed, the phenomenon that ions in liquid crystal are acquired by an oriented film interface of the liquid crystal due to the fact that the distance of the ions in the liquid crystal moving along a certain direction is too large is avoided, and the ghost problem of liquid crystal display is improved.
Referring to fig. 2, in some embodiments, the method for improving the image sticking further includes the following steps:
step S32, if the information Zn +1 is judged to be different from the information Zn, whether the times of displaying the information Zn in positive polarity and the times of displaying the information Zn in reverse polarity are equal is further judged;
step S321, if the voltage is equal to the first frame, controlling the polarity of the driving voltage to be inverted, and displaying the (n + 1) th frame;
step S322, if the voltages are not equal, controlling the polarity of the driving voltage to reverse, and displaying the nth frame of picture first and then displaying the (n + 1) th frame of picture.
The method for improving the ghost image comprises the steps of obtaining information Zn of an nth frame and information Zn +1 of an n +1 th frame, and further judging whether the times of displaying the information Zn in a positive polarity and the times of displaying the information Zn in a reverse polarity are equal or not on the basis of judging that the information Zn +1 of the n +1 th frame is different from the information Zn of the nth frame, namely judging whether the distance of ions in the liquid crystal moving along the positive direction is equal to the distance of ions in the reverse direction or not. If the number of times of displaying the information Zn in the positive polarity is equal to the number of times of displaying the information Zn in the reverse polarity, the distance of the ions in the liquid crystal moving in the positive direction and the distance of the ions in the liquid crystal moving in the reverse direction are mutually offset, and if the number of times of displaying the information Zn in the positive polarity is not equal to the number of times of displaying the information Zn in the reverse polarity, the distance of the ions in the liquid crystal moving in the positive direction and the distance of the ions in the reverse direction are not offset.
In the method for improving the ghost, after the information Zn +1 is judged to be different from the information Zn, and the times of displaying the information Zn in the positive polarity and the times of displaying the information Zn in the reverse polarity are judged to be equal, the polarity of the driving voltage is controlled to be reversed, and the frame of the n +1 frame is displayed after the information Zn +1 is judged to be different from the information Zn, and the times of displaying the information Zn in the positive polarity and the times of displaying the information Zn in the reverse polarity are judged to be unequal, the polarity of the driving voltage is controlled to be reversed, the frame of the n is displayed firstly, and then the frame of the n +1 frame is displayed. When two continuous frames of pictures are different, whether the moving distance of ions in the liquid crystal along the positive direction and the moving distance of the ions in the liquid crystal along the negative direction are mutually counteracted is judged, if the moving distances of the ions in the liquid crystal along the positive direction and the moving distances of the ions in the liquid crystal along the negative direction are mutually counteracted, the (n + 1) th frame of picture can be directly displayed after the polarity of the control driving voltage is reversed, if the moving distances of the ions in the liquid crystal along the positive direction and the moving distances of the ions in the negative direction are not counteracted, the (n + 1) th frame of picture is displayed, and the effects of eliminating direct current residual images and improving the residual image problem of liquid crystal display are achieved.
It should be noted that, under the condition that the distance that the ions in the liquid crystal move in the forward direction and the distance that the ions move in the reverse direction are not offset, although the control driving voltage polarity is reversed, and then a frame of the nth frame of picture is displayed, in the currently common display device, the human eye cannot observe the delay time of displaying a frame of picture, therefore, after the distance that the ions in the liquid crystal move in the forward direction and the distance that the ions move in the reverse direction are not offset, the display effect is not negatively affected by displaying a frame of the nth frame of picture, so that the direct current ghost can be eliminated on the basis of ensuring the display effect, and the ghost problem of the liquid crystal display can be improved. In addition, the display of information with positive polarity and the display of information with reverse polarity in the above embodiments mean that the polarities of the driving voltages of two consecutive frames are reversed, and it is not limited that any one of the polarities is positive or negative.
In some embodiments, in the step of displaying the n +1 th frame, the time for displaying the n th frame is controlled to be 1/120 to 1/60 second, that is, when it is determined that the distance of the ions in the liquid crystal moving in the forward direction and the distance of the ions in the liquid crystal moving in the reverse direction are not offset, the time for displaying the n th frame is controlled to be 1/120 to 1/60 second, the frame delay time caused by displaying more than one frame of the n th frame after the polarity inversion of the driving voltage is controlled to be 1/120 to 1/60 second, the number of the visual frames in the human eye concentration state is 30 frames per second, and the number of the visual frames in the relaxed state is 24 frames per second.
In some embodiments, the step of determining whether the number of times of displaying the information Zn in the positive polarity is equal to the number of times of displaying the information Zn in the reverse polarity specifically includes:
s32a, acquiring the frame number a of information Zn continuously displayed;
step S32b, judging whether a is an even number;
step S32c, if a is an even number, judging that the number of times of displaying the information Zn in positive polarity is equal to the number of times of displaying the information Zn in reverse polarity;
and step S32d, if the a is not an even number, judging that the times of displaying the information Zn in positive polarity and the times of displaying the information Zn in reverse polarity are not equal.
Referring to fig. 3 and 4, in an embodiment, a method for improving image sticking includes:
s1, acquiring information Zn of an nth frame of picture and information Zn +1 of an n +1 th frame of picture;
s2, judging whether the information Zn +1 is the same as the information Zn;
step S32a, if the information Zn +1 is judged to be different from the information Zn, acquiring the frame number a of the information Zn in continuous display;
step S32b, judging whether a is an even number;
step S32c, if a is an even number, controlling the polarity of the driving voltage to be reversed, and displaying the (n + 1) th frame picture;
step S32d, if a is not an even number, controlling the polarity of the driving voltage to be reversed, firstly displaying the nth frame picture, and then displaying the (n + 1) th frame picture;
after the information Zn +1 is judged to be different from the information Zn, the frame number a is reset to 1 so as to record the frame number continuously displayed by the information Zn +1;
after the n +1 th frame picture is displayed, n = n +1 is noted, and the above steps are repeated until the last frame picture.
In the above embodiment, by acquiring the number of frames a of continuous display of the information Zn, and according to whether a is an even number, it is determined whether the number of times that the information Zn is displayed in the positive polarity is equal to the number of times that the information Zn is displayed in the reverse polarity, and only by acquiring the number of frames of continuous display of the information Zn and determining whether the number of times that the information Zn is displayed in the positive polarity is an even number, a complicated step is not required, so that the determination process of whether the number of times that the information Zn is displayed in the positive polarity is equal to the number of times that the information Zn is displayed in the reverse polarity is simple and quick.
In some embodiments, the method for improving afterimage further comprises the steps of: and step S32b1, resetting the frame number a to 1 after judging that the information Zn +1 is different from the information Zn, and recording the frame number continuously displayed by the information Zn +1. For example, in one embodiment, the display process of one screen has x different information, the number of frames displayed continuously on the screen corresponding to each information is sequentially marked as a1, a2 \8230;, ax, and the number of frames displayed continuously on the screen corresponding to two adjacent information Zn and Zn +1 in the display time sequence is an and an +1, respectively. In the process of continuously displaying the picture corresponding to the information Zn, the number of frames an continuously displayed on the picture corresponding to the information Zn increases frame by frame along with the display of the picture, after an frame is displayed on the picture corresponding to the information Zn, the information Zn +1 of the next frame picture is different from Zn, the number of frames an is not continuously increased when the number of frames is recorded, but the number of frames is reset to 1, the number of frames continuously displayed on the information Zn +1 is recorded by an +1=1, the independent counting of the number of frames continuously displayed on the picture corresponding to each kind of information is realized, namely, the number of frames continuously displayed on the changed picture is restarted when the picture information is changed, and the load of the calculated number of frames of the product is prevented from increasing due to the continuous accumulation of the number of frames continuously displayed on the pictures corresponding to different information. And the changed frame number of continuous display of the picture is restarted when the picture information is changed, so that the process of judging whether the times of displaying the information Zn in positive polarity and the times of displaying the information Zn in reverse polarity are equal or not according to whether a is an even number or not by acquiring the frame number a of continuous display of the information Zn does not need complicated calculation, and the steps required by the judging process are simplified.
In the above embodiment, the method for improving afterimage further includes the following steps: after the n +1 th frame picture is displayed, n = n +1 is noted, and the above steps are repeated until the last frame picture.
Referring to fig. 5, in an embodiment, the method for improving the image sticking includes:
s1, acquiring information Zn of an nth frame of picture and information Zn +1 of an (n + 1) th frame of picture;
s2, judging whether the information Zn +1 is the same as the information Zn or not;
s31, if the display images are the same, controlling the polarity of the driving voltage to be reversed, and displaying the (n + 1) th frame of image;
step S32a, if the information Zn +1 is judged to be different from the information Zn, acquiring the frame number a continuously displayed by the information Zn;
step S32b, judging whether the frame number a is an even number;
step S32c, if a is an even number, controlling the polarity of the driving voltage to be reversed, and displaying the picture of the (n + 1) th frame;
and step S32d, if the number a is not an even number, controlling the polarity of the driving voltage to be reversed, and displaying the nth frame picture and then displaying the (n + 1) th frame picture.
After the information Zn +1 is judged to be different from the information Zn, the frame number a is reset to 1 so as to record the frame number continuously displayed by the information Zn +1;
after the n +1 th frame picture is displayed, n = n +1 is noted, and the above steps are repeated until the last frame picture.
In the method for improving the afterimage, whether the information Zn +1 of the (n + 1) th frame is the same as the information Zn of the nth frame is judged, and if the information Zn +1 of the (n + 1) th frame is the same as the information Zn of the nth frame, the driving voltage is controlled to display the (n + 1) th frame after polarity inversion, and after the polarity inversion, the number of times of polarity inversion a = a +1 is recorded. When the same picture is continuously displayed, the polarity is timely changed, so that the overlarge moving distance of ions in the liquid crystal along a certain direction is avoided. If the information Zn +1 of the (n + 1) th frame picture is different from the information Zn of the (n) th frame picture, judging whether the polarity inversion frequency is an even number, if the polarity inversion frequency is the even number, showing that the positive and negative polarity display frequency is equal, namely the distance of the ions in the liquid crystal moving along the positive direction and the distance of the ions in the liquid crystal moving along the negative direction are mutually offset, directly displaying the (n + 1) th frame picture after the polarity inversion without generating direct current residual images, and recording the polarity inversion frequency a =1; if the number of times of polarity inversion is not even, it means that the number of times of positive and negative polarity display is not equal, i.e. the distance that the ions in the liquid crystal move in the positive direction and the distance that the ions move in the negative direction are not offset, the polarity inversion is controlled, firstly the nth frame of picture is displayed, the distance that the ions move in the positive and negative directions is offset, and then the (n + 1) th frame of picture is displayed. After the n +1 frame picture, note n = n +1, and repeat the above steps until the last frame picture. The method for improving the residual image can make the positive and negative moving distances of the ions offset by detecting whether the positive and negative polarity conversion times are equal or not, eliminate the direct current residual image and improve the residual image problem of the liquid crystal display.
