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, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic flow chart of a display frame compensation method according to an embodiment of the present disclosure. As shown in fig. 1, an embodiment of the present application provides a display image compensation method for compensating a display image of a display panel. The display picture compensation method comprises the following steps:
s101, acquiring an initial video signal, and identifying a time sequence relation of the initial video signal, wherein the time sequence relation comprises the length of a non-data updating period V-blk.
S102, judging whether the length of the non-data updating period V-blk meets the detection conditions of threshold voltage and mobility.
And S103, if the threshold voltage and the mobility are not satisfied, adjusting the timing relationship to obtain a new timing relationship which satisfies the detection conditions of the threshold voltage and the mobility.
And S104, compensating the initial video signal according to the new time sequence relation.
In step S101, please refer to fig. 2, and fig. 2 is a specific schematic diagram of a timing relationship of an initial video signal before adjustment according to an embodiment of the present application. Referring to fig. 1 and 2, the timing relationship includes a frame frequency f, a resolution, a length of the non-data update period V-blk, and a length of the data update period V-act of the video signal. The frame frequency f, the resolution, the length of the non-data updating time period V-blk and the length of the data updating time period V-act of the video signal are identified and then automatically stored.
In step S102, the shortest time period required for detecting the threshold voltage Vth and the mobility u for compensating the video signal is the length of the non-data updating period V-blk. Therefore, the step S102 is specifically: and judging whether the length of the non-data updating period V-blk is larger than or equal to the detection time required for detecting the threshold voltage and the mobility. Of course, if the length of the non-data update period V-blk is greater than or equal to the detection time required for detecting the threshold voltage and the mobility, the threshold voltage and the mobility may be directly detected and then compensated.
In step S103, if the length of the non-data update period V-blk is less than the detection time required for detecting the threshold voltage and the mobility, the length of the non-data update period V-blk needs to be adjusted. Referring to fig. 3, fig. 3 is a specific diagram illustrating the timing relationship of the initial video signal after adjustment according to the embodiment of the present application. As shown in fig. 3, in the specific adjustment operation, the frame rate and the resolution are kept unchanged, and the length of the non-data updating period V-blk is changed, so that the length of the non-data updating period V-blk is greater than or equal to the detection time required for detecting the threshold voltage and the mobility. Preferably, the length of the non-data update period V-blk is slightly larger than the detection time.
In step S104, after obtaining the new timing relationship, the initial video signal may be adjusted according to the new timing relationship, and then compensation operation is performed.
Specifically, this step S104 includes the following substeps: s1041, adjusting the initial video signal according to the new time sequence relation to obtain a target video signal with adjusted time sequence; s1042, detecting the threshold voltage and the mobility of the target video signal to obtain the threshold voltage and the mobility required by the compensation of the target video signal; and S1043, compensating the target video signal according to the threshold voltage and the mobility.
In step S1041, when the initial video signal is adjusted, the frame frequency f is kept unchanged, and the ratio of the length of the non-data updating period V-blk to the length of the data updating period V-act is adjusted, so that the initial video signal is converted into a target video signal whose length of the non-data updating period V-blk is greater than or equal to the detection time.
In step S1042, the threshold voltage and the mobility of the target video signal are detected during a non-data update period V-blk.
It is understood that, in some embodiments, in order to improve the compensation effect, a still picture and a non-still picture can be distinguished, and the step S1042 may include the following steps:
s10421, judging whether a display picture corresponding to the target video signal is a static picture;
s10422, if the display picture is a static picture, preprocessing the static picture to reduce the power consumption of the display picture, thereby obtaining a preprocessed target display picture;
s10423, detecting the target display picture to acquire threshold voltage data and mobility; s10423, if the display picture is a non-static picture, directly detecting the display picture to obtain a threshold voltage and a mobility rate; and S10424, compensating the target video signal according to the threshold voltage and the mobility parameter.
The manner of determining whether the display screen is still includes, but is not limited to, the current frame being consistent with the previous consecutive frames of display screen data, and if the (n + m) th frame is consistent with the (n + m-1) th to (n + m-1) th frames of display screen data, the display screen is determined to be a still display screen at this time. The preprocessing mode can be to reduce the brightness of the display picture, thereby reducing the power consumption of the display picture. Of course, the way of reducing the brightness of the display screen can be many.
In some embodiments, the brightness of the display image may be gradually decreased to a preset brightness value according to the increase of the frame number of the still image, so as to obtain the preprocessed target display image.
In some embodiments, the target display picture after the preprocessing may be obtained by directly decreasing the brightness of the display picture to a preset brightness value after increasing the frame number of the still picture to a preset frame number.
As can be seen from the above, in the embodiment of the present application, an initial video signal is obtained, and a timing relationship of the initial video signal is identified, where the timing relationship includes a length of a non-data update period V-blk; judging whether the length of the non-data updating period V-blk meets the detection conditions of threshold voltage and mobility or not; if not, adjusting the timing relationship to obtain a new timing relationship meeting the detection conditions of the threshold voltage and the mobility; compensating the initial video signal according to the new time sequence relation; therefore, the compensation of the video signal is realized, and the time sequence relation is adjusted before the compensation, so that the condition that the threshold voltage and the mobility cannot be detected due to the fact that the length of the non-data updating time period V-blk is smaller than the detection time is avoided; thereby improving the reliability of compensation and improving the uniformity of the brightness of the display picture.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a display frame compensation apparatus according to an embodiment of the present disclosure. As shown in fig. 4, the display picture compensation apparatus includes: the device comprises an acquisition module 201, a judgment module 202, an adjustment module 203 and a compensation module 204.
The acquiring module 201 is configured to acquire an initial video signal and identify a timing relationship of the initial video signal, where the timing relationship includes a length of a non-data update period V-blk; as shown in fig. 2, the timing relationship includes a frame frequency f, a resolution, a length of the non-data update period V-blk, and a length of the data update period V-act of the video signal. The frame frequency f, the resolution, the length of the non-data updating time period V-blk and the length of the data updating time period V-act of the video signal are identified and then automatically stored.
The determining module 202 is configured to determine whether the length of the non-data updating period V-blk satisfies the detection conditions of the threshold voltage and the mobility; since the shortest time period required for the detection of the threshold voltage Vth and the mobility u for compensating the video signal is the length of the non-data update period V-blk. Therefore, the determining module 202 is specifically configured to: and judging whether the length of the non-data updating period V-blk is larger than or equal to the detection time required for detecting the threshold voltage and the mobility. Of course, if the length of the non-data update period V-blk is greater than or equal to the detection time required for detecting the threshold voltage and the mobility, the threshold voltage and the mobility may be directly detected and then compensated.
The adjusting module 203 is configured to adjust the timing relationship if the threshold voltage is not satisfied, so as to obtain a new timing relationship that satisfies the detection conditions of the threshold voltage and the mobility. If the length of the non-data updating period V-blk is less than the detection time required for detecting the threshold voltage and the mobility, the length of the non-data updating period V-blk needs to be adjusted, as shown in fig. 3, during the adjustment operation, the frame frequency and the resolution are kept unchanged, and the length of the non-data updating period V-blk is changed, so that the length of the non-data updating period V-blk is greater than or equal to the detection time required for detecting the threshold voltage and the mobility. Preferably, the length of the non-data update period V-blk is slightly larger than the detection time.
The compensation module 204 is configured to compensate the initial video signal according to the new timing relationship. After the new timing relationship is obtained, the initial video signal can be adjusted according to the new timing relationship, and then compensation operation is performed.
Specifically, the compensation module 204 includes: the adjusting unit is used for adjusting the initial video signal according to the new time sequence relation so as to obtain a target video signal with the adjusted time sequence; the detection unit is used for detecting the threshold voltage and the mobility of the target video signal so as to acquire the threshold voltage and the mobility required by compensating the target video signal; and the compensation unit is used for compensating the target video signal according to the threshold voltage and the mobility. When the initial video signal is adjusted, the frame frequency f of the initial video signal is kept unchanged, and the proportion of the length of the non-data updating period V-blk and the length of the data updating period V-act is adjusted, so that the initial video signal is converted into a target video signal of which the length of the non-data updating period V-blk is greater than or equal to the detection time. Wherein, the detection of the threshold voltage and the mobility of the target video signal is performed in a non-data updating period V-blk.
It is understood that, in some embodiments, in order to improve the compensation effect, a still picture and a non-still picture can be distinguished, and the detection unit can be configured to: judging whether a display picture corresponding to the target video signal is a static picture or not; if the display picture is a static picture, preprocessing the static picture to reduce the power consumption of the display picture so as to obtain a preprocessed target display picture; detecting the target display picture to acquire threshold voltage data and mobility; and if the display picture is a non-static picture, directly detecting the display picture to acquire the threshold voltage and the mobility.
The manner of determining whether the display screen is still includes, but is not limited to, the current frame being consistent with the previous consecutive frames of display screen data, and if the (n + m) th frame is consistent with the (n + m-1) th to (n + m-1) th frames of display screen data, the display screen is determined to be a still display screen at this time. The preprocessing mode can be to reduce the brightness of the display picture, thereby reducing the power consumption of the display picture. Of course, the way of reducing the brightness of the display screen can be many.
In some embodiments, the brightness of the display image may be gradually decreased to a preset brightness value according to the increase of the frame number of the still image, so as to obtain the preprocessed target display image.
In some embodiments, the target display picture after the preprocessing may be obtained by directly decreasing the brightness of the display picture to a preset brightness value after increasing the frame number of the still picture to a preset frame number.
As can be seen from the above, in the embodiment of the present application, an initial video signal is obtained, and a timing relationship of the initial video signal is identified, where the timing relationship includes a length of a non-data update period V-blk; judging whether the length of the non-data updating period V-blk meets the detection conditions of threshold voltage and mobility or not; if not, adjusting the timing relationship to obtain a new timing relationship meeting the detection conditions of the threshold voltage and the mobility; compensating the initial video signal according to the new time sequence relation; therefore, the compensation of the video signal is realized, and the time sequence relation is adjusted before the compensation, so that the condition that the threshold voltage and the mobility cannot be detected due to the fact that the length of the non-data updating time period V-blk is smaller than the detection time is avoided; thereby improving the reliability of compensation and improving the uniformity of the brightness of the display picture.
