Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application are within the scope of protection of the present application.
The present application provides a display image adjusting method, which is applied to a display panel 1, please refer to fig. 1 and fig. 2 together, and fig. 1 is a schematic flow chart of the display image adjusting method according to an embodiment of the present application; fig. 2 is a schematic top view of a display panel according to an embodiment of the present disclosure. The display picture adjusting method comprises the following steps: steps S101, S102, S103, S104, and S105, wherein the steps S101, S102, S103, S104, and S105 are described in detail as follows.
S101, acquiring an initial display picture of the display panel;
s102, dividing the initial display picture into a plurality of detection areas;
s103, calculating the static time of the unchanged display picture of each detection area;
s104, judging the relation between the static time and a first preset threshold value;
when the static time is less than a first preset threshold, S105, controlling the entire initial display frame to move towards a first direction or a direction opposite to the first direction.
It should be noted that the display panel 1 is an OLED display screen, as shown in fig. 2, the display panel 1 has a display area 1c and a non-display area 1d, the non-display area 1d is surrounded on the display area 1c, a plurality of pixel units 11 of an array subsection, a plurality of driving signal lines 12 and a plurality of data signal lines 13 are arranged in the display area 1c, and the corresponding pixel units 11 receive data signals transmitted by the data signal lines 13 under the excitation of driving signals transmitted by the driving signal lines 12, and operate under the loading of the data signals, so as to realize the display of a picture. The pixel unit 11 generally includes three color sub-pixels 111 of red (R), green (G), and blue (B), and the data signal received by each color sub-pixel 111 may be different, and it can be understood that, under the loading of the data signal, the larger the charging current provided for the color sub-pixel 111, the larger the light-emitting luminance of the color sub-pixel 111, and the lower the light-emitting efficiency of the blue color sub-pixel 111, the larger the current is required to achieve the same light-emitting luminance as the red and green color sub-pixels 111.
As can be understood, the display panel 1 generally includes an effective display area and a reserved display area, in this embodiment, even when the display panel 1 performs a full-screen display, the initial display screen 1a does not completely occupy the entire display area 1c, in other words, when the display panel 1 displays the initial display screen 1a, a part of the pixel units 11 are not operated, and there is no influence on the display of the initial display screen 1a, and in general, the pixel units 11 for displaying the initial display screen 1a are adjacent to the pixel units 11 that are not operated at least in a certain direction. In the present embodiment, the pixel cell 11 for displaying the initial display screen 1a is adjacent to the non-operating pixel cell 11 in the first direction D1. Accordingly, the initial display screen 1a can be controlled to be displaced in the first direction D1 or the opposite direction to the first direction D1 as a whole.
Specifically, before controlling the overall displacement of the initial display screen 1a, the step S103 and the step S104 calculate the stationary time and determine the relationship between the stationary time and the first preset threshold, so as to determine whether the display screen in the detection area 1b is stationary, that is, whether the data signal in the detection area 1b has not changed and whether the display screen has not changed. In this embodiment, if the first preset threshold is 10 seconds, that is, if the time during which the display screen in the detection area 1b does not change exceeds 10 seconds, it is determined that the display screen in the detection area 1b is still, and if not, it is determined that the display screen is dynamic. It is understood that, in other possible embodiments, the first preset threshold may also be other values, which are not limited in this application.
It can be understood that, for a static display screen, the display brightness may be high, and the current supplied to the pixel unit 11 by the data signal is also high, which may cause the pixel unit 11 in the detection area 1b to generate too high heat, which may affect the life of the pixel unit 11. Therefore, in the present embodiment, before controlling the initial display screen 1a to be entirely displaced in the first direction D1 or the direction opposite to the first direction D1, it is necessary to determine the display screen in each of the detection regions 1b, and if the display screen in the detection region 1b is still, it may be necessary to reduce the display luminance of the pixel cells 11 in the detection region 1 b; if the display screen in the detection area 1b is dynamic, the entire initial display screen 1a is controlled to be displaced in a first direction D1 or a direction opposite to the first direction D1.
It can be understood that, in the present embodiment, by moving the initial display screen 1a as a whole, the pixel units 11 in the display panel 1 can be prevented from displaying the same brightness for a long time, so that the blue sub-pixels in the pixel units 11 are prevented from operating for a long time, and the service life of the blue sub-pixels is improved. Meanwhile, as the initial display picture 1a moves integrally, the change of the display picture cannot be easily perceived by naked eyes of people, and the use experience of the display panel 1 is ensured.
In a possible implementation manner, referring to fig. 1 again, the display screen adjusting method further includes: steps S106 and S107, wherein the steps S106 and S107 are described in detail as follows.
When the static time is greater than or equal to the first preset threshold, S106, calculating the average display brightness in the detection area;
s107, judging the relation between the average brightness and a second preset threshold value;
when the average display luminance is less than a second preset threshold, S105, the entire initial display screen 1a is controlled to be displaced in a first direction D1 or a direction opposite to the first direction D1.
In the present embodiment, when the still time is greater than or equal to the first preset threshold, it is determined that the display screen in the detection area 1b is still, and step S106 calculates an average value of the display luminance of each pixel unit 11 in the detection area 1b, so as to obtain the average display luminance. When the average display brightness is smaller than the second preset threshold, it indicates that the display screen in the detection area 1b is still, but the average display brightness of the pixel units 11 is not too high, so that the pixel units 11 do not generate heat seriously, and the display brightness of the pixel units 11 does not need to be adjusted. Specifically, the second preset threshold is 75% of the target gray-scale luminance of the detection region 1b, and the target gray-scale luminance may be set manually according to the design of the pixel unit 11, the circuit, and the like of the display panel 1.
It is understood that the display brightness of the pixel unit 11 can be calculated by the magnitude of the current value charging the pixel unit 11, and can also be calculated by other manners, and the second preset threshold value can also be other values, which is not limited in this application.
In a possible implementation manner, referring to fig. 1 again, the display screen adjusting method further includes: step S108, wherein the detailed description of step S108 is as follows.
When the average display brightness is greater than or equal to the second preset threshold, S108, controlling the average display brightness to be less than or equal to a third preset threshold; wherein the third preset threshold is smaller than the second preset threshold.
In the present embodiment, when the average display luminance is greater than or equal to the second preset threshold, it means that the average display luminance of the pixel unit 11 in the detection region 1b is too high, which easily causes heat generation of the pixel unit 11 and affects the service life of the pixel unit 11. Therefore, by controlling the magnitude of the current for charging the pixel unit 11 in the detection area 1b, the average display brightness is controlled to be less than or equal to the third preset threshold, so that the average display brightness in the detection area 1b is reduced, excessive heat generation of the pixel unit 11 is avoided, and the service life of the pixel unit 11 is prolonged. Specifically, the third preset threshold is 50% of the target gray scale brightness of the detection area 1 b.
It is understood that, in other possible embodiments, the third preset threshold may also be other values as long as the third preset threshold is not affected to be smaller than the second preset threshold, which is not limited in the present application.
In one possible implementation, please refer to fig. 3, and fig. 3 is a schematic top view of a display panel according to another implementation of the present disclosure. The step of controlling the displacement of the entire initial display screen 1a in the first direction D1 or the direction opposite to the first direction D1, in which the display panel 1 includes a first display area 1e and a second display area 1f adjacent to each other in the first direction D1, and the initial display screen 1a is located in the first display area 1e, specifically includes:
controlling the initial display picture 1a to be entirely displaced to the second display area 1f by at least a part; alternatively, the first and second electrodes may be,
and controlling the whole displaced display screen to be displaced at least partially towards the first display area 1 e.
In this embodiment, the first display area 1e is an effective detection area 1b of the display panel 1, the second display area 1f is a reserved detection area 1b of the display panel 1, and reference is made to the above description for the description of the effective detection area 1b and the reserved detection area 1b, which is not repeated herein.
Specifically, since the initial display screen 1a is located in the first display area 1e and the pixel units 11 in the second display area 1f are not displayed, the initial display screen 1a may be controlled to be entirely displaced toward the second display area 1f by at least a portion. It is understood that, in the present embodiment, after the initial display screen 1a is entirely displaced toward the second display area 1f by at least a portion, a portion of the pixel unit 11 on a side of the first display area 1e away from the second display area 1f enters an inactive state from an active state, in other words, a portion of the first display area 1e on a side away from the second display area 1f is changed from the active detection area 1b to reserve the detection area 1 b. Therefore, the entire displaced display screen may be controlled to be displaced at least partially toward the first display area 1e, that is, only a small portion of the second display area 1f needs to be reserved, so that the initial display screen 1a may be displaced in multiple ways in the first direction D1, thereby achieving the purpose of improving the service life of the blue sub-pixel in the pixel unit 11.
For example, the whole initial display frame 1a may be controlled to be shifted to the second display area 1f by one unit, and then the whole initial display frame 1a may be controlled to be shifted to the first display area 1e by one unit, and so on; alternatively, the entire initial display screen 1a may be controlled to be shifted to the second display area 1f by one unit, then the entire initial display screen 1a may be controlled to be shifted to the first display area 1e by one unit … …, and so on, which is not limited in this application.
It is understood that, in other possible embodiments, if the display area 1c includes a reserved display area in the second direction D2, the initial display screen 1a may be controlled to be displaced in the second direction D2 or a direction opposite to the second direction D2 as a whole, which is not limited in the present application.
It can be understood that, in order to prevent the display frame from having the problem of image sticking, at least a certain time interval is required after the initial display frame 1a is displaced and before the next displacement is performed, and meanwhile, the time interval should be greater than the first preset threshold, otherwise, the initial display frame 1a is displaced before the display frame of the detection area 1b is determined to be still.
Specifically, in the present embodiment, the interval time is 15 seconds. In other possible embodiments, the interval time may also be other values as long as the interval time is not affected by being greater than the first preset threshold, which is not limited in the present application.
In one possible implementation, please refer to fig. 4, in which fig. 4 is a schematic diagram of displacement unit division according to an embodiment of the present disclosure. The display screen adjusting method further comprises the following steps:
dividing the display area 1c into n displacement units 1g extending in a second direction D2; wherein the second direction D2 is perpendicular to the first direction D1, n is a positive integer;
the step of controlling the initial display screen 1a to be entirely displaced to at least a part of the second display area 1f specifically includes:
traversing i displacement units 1g, and replacing the display picture of the ith displacement unit 1g to the display picture of the (i + 1) th displacement unit 1 g;
the step of controlling the displaced display screen to be displaced at least partially to the first display area 1e as a whole specifically includes:
traversing i displacement units 1g, and replacing the display picture of the ith displacement unit 1g with the display picture of the ith-1 displacement unit 1 g;
wherein i is a positive integer and 0< i < n.
In the present embodiment, as shown in fig. 4, a boundary between two displacement units 1g coincides with a boundary between the first display area 1e and the second display area 1 f. It can be understood that traversing i of the displacement units 1g means taking a value for i within a positive integer value range of 1 to n-1. The reason why i displacement units 1g are traversed instead of n displacement units 1g is that in the first direction D1, the displacement units 1g located on the side boundary of the first display area 1e facing away from the second display area 1f, or the displacement unit 1g located at the boundary of the second display area 1f on the side away from the first display area 1e may not have the displacement unit 1g replaceable in the replacement process of the display screen, and therefore, in the present embodiment, by traversing i displacement units 1g, the remaining displacement units 1g are displaced by one displacement unit 1g in the direction of the first display area 1e or the second display area 1f, except for the displacement unit 1g located at the boundary of the first display area 1e or the second display area 1 f.
It can be understood that, since the initial display screen 1a is located in the displacement unit 1g which is at least partially continuous, the overall displacement of the initial display screen 1a can be realized by traversing i displacement units 1g to replace the display screen.
Specifically, when the initial display screen 1a is controlled to be entirely shifted to the second display area 1f at least partially, the display screen of the i-th displacement unit 1g is replaced with the display screen of the i + 1-th displacement unit 1g by traversing the i displacement units 1g, so that the initial display screen 1a is entirely shifted to the second display area 1f by one displacement unit 1 g.
It is understood that, since the entire initial display screen 1a is shifted by one displacement unit 1g toward the second display area 1f and the initial display screen 1a is no longer adjacent to the boundary of the first display area 1e in the first direction D1, the entire initial display screen 1a can be shifted by one displacement unit 1g toward the first display area 1e by traversing i displacement units 1g and replacing the display screen of the i-th displacement unit 1g with the display screen of the i-1 th displacement unit 1g after controlling the entire shifted display screen to be shifted at least partially toward the first display area 1 e.
In a possible implementation manner, please refer to fig. 5, and fig. 5 is a partially enlarged schematic view of a display panel according to an embodiment of the present disclosure. The display panel 1 comprises a plurality of pixel units 11 distributed in an array, and an orthographic projection of the displacement unit 1g on the display panel 1 covers 1-3 columns of the pixel units 11 which are continuous in the first direction D1.
For example, when the orthographic projection of the displacement unit 1g on the display panel 1 covers 2 rows of the pixel units 11 which are continuous in the first direction D1, replacing the display screen of the ith displacement unit 1g with the display screen of the (i + 1) th displacement unit 1g may be replacing the display screen of the pixel unit 11 in the 1 st row with the display screen of the pixel unit 11 in the 3 rd row, and replacing the display screen of the pixel unit 11 in the 2 nd row with the display screen of the pixel unit 11 in the 4 th row; the display of the pixel unit 11 in the 3 rd column is replaced by the display of the pixel unit 11 in the 5 th column, the display of the pixel unit 11 in the 4 th column is replaced by the display … … of the pixel unit 11 in the 6 th column, and so on.
It can be understood that, in order to avoid that the displacement of the initial display frame 1a can be easily detected by human eyes, the number of columns of the pixel units 11 that are replaced at one time during each displacement of the initial display frame 1a is not too large. In the present embodiment, the orthographic projection of the displacement unit 1g on the display panel 1 covers 1-3 columns of the pixel cells 11 which are consecutive in the first direction D1.
In one possible implementation manner, referring to fig. 4 again, the display panel 1 includes a plurality of data signal lines 13 extending along the second direction D2, and the step of replacing the display frame of the ith displacement unit 1g with the display frame of the (i + 1) th displacement unit 1g specifically includes:
acquiring a data signal transmitted on the data signal line 13 correspondingly arranged on the ith displacement unit 1 g;
transmitting the data signals to the data signal lines 13 correspondingly disposed at the (i + 1) th displacement unit 1g, respectively;
the step of replacing the display screen of the ith displacement unit 1g with the display screen of the ith-1 displacement unit 1g specifically includes:
acquiring a data signal transmitted on the data signal line 13 correspondingly arranged on the ith displacement unit 1 g;
the data signals are transmitted to the data signal lines 13 correspondingly disposed at the i-1 th displacement unit 1g, respectively.
It is understood that there are various ways to control the displacement of the entire initial display screen 1a in the first direction D1 or the direction opposite to the first direction D1, for example, changing the driving signal transmitted on the corresponding driving signal line 12 or changing the data signal transmitted on the corresponding data signal line 13 can be achieved.
In addition, in a normal case, the voltage value of the driving signal is high, and the entire initial display screen 1a is controlled to be displaced in the first direction D1 or the direction opposite to the first direction D1 by switching between high and low levels of the driving signal, which causes high power consumption. However, the voltage value of the data signal is relatively low, and therefore, in the present embodiment, by changing the data signal transmitted corresponding to the data signal line 13, power consumption of the initial display screen 1a during the shifting process can be saved.
In a possible implementation manner, referring to fig. 1 again, the display screen adjusting method further includes: step S109, wherein step S109 is described in detail as follows.
S109, calculating the number of times of displacement of the initial display screen 1 a;
and when the number of times of displacement of the initial display picture 1a is greater than or equal to a preset number of times, restoring the initial display picture 1a to the initial position.
As shown in fig. 1, when the number of times of displacement of the initial display screen 1a is less than a preset number of times, the initial display screen 1a is still displaced at a certain time interval. Specifically, after the number of times of displacement of the initial display frame 1a is greater than or equal to a preset number of times, the initial display frame 1a is restored to an initial position, that is, in the present embodiment, the initial display frame 1a is restored to correspond to the first display area 1 e. It can be understood that resetting the position of the initial display frame 1a after the initial display frame 1a is displaced for a certain number of times can avoid unnecessary power consumption waste caused by the replacement of the display frame being performed all the time.
In this embodiment, the preset number of times is 3 times. It is understood that, in other possible embodiments, the preset number may be other values, which are not limited in the present application.

The display panel 1 comprises a first latch 14, a second latch 15, an inverter 16, a first switch unit 17, a second switch unit 18 and a processor 19, wherein a first end C1 of the first latch 14 is electrically connected with a first end C1 of the second latch 15 for receiving a counting signal, a second end D of the first latch 14 is electrically connected with an output end of the inverter 16, and a third end Q of the first latch 14 is electrically connected with a second end D of the second latch 15 and an input end of the inverter 16; a third terminal Q of the second latch 15 is electrically connected to the gate of the first switching unit 17 and the gate of the second switching unit 18; a first electrode of the first switch unit 17 is configured to receive a first voltage signal, and a second electrode of the first switch unit 17 is electrically connected to a first electrode of the second switch unit 18; the second electrode of the second switch unit 18 is used for receiving a ground signal; the second electrode of the first switch unit 17 or the first electrode of the second switch unit 18 is used for outputting a reset signal, and the processor 19 controls the display panel 1 to display an initial display frame 1a according to the reset signal.
In this embodiment, the first switch unit 17 is a P-type field effect transistor, and when the signal level received by the first switch unit 17 is a low level, the first electrode and the second electrode of the first switch unit 17 are turned on, so as to output the first voltage signal to the processor 19 through the second electrode of the first switch unit 17; the second switch unit 18 is an N-type field effect transistor, and when the signal level received by the second switch unit 18 is a high level, the first electrode and the second electrode of the second switch unit 18 are conducted, so that the ground signal is output to the processor 19 as the reset signal through the first electrode of the second switch unit 18.
Specifically, in an initial state, the third terminal Q of the second latch 15 outputs a low level, the first switching unit 17 is turned on, and the second switching unit 18 is turned off, so that the first voltage signal is output to the processor 19. Each time the initial display frame 1a moves as a whole, the count signal received by the first latch 14 generates a rising edge, i.e., the count signal changes from a low level to a high level. Next, the counting process of the first latch 14 and the second latch 15 will be described in detail.
When the count signal rises to the high level for the first time, the first terminal C1 of the first latch 14 receives the high level, and the third terminal Q of the first latch 14 outputs the low level, and is changed to the high level by the inverter 16, and is input to the second terminal D of the first latch 14; the first terminal C1 of the second latch 15 receives a high level, the second terminal D of the second latch 15 receives a low level outputted from the third terminal Q of the first latch 14, and the output from the third terminal Q of the second latch 15 is still a low level;
when the count signal rises to a high level for the second time, the first terminal C1 of the first latch 14 receives the high level, and the third terminal Q of the first latch 14 outputs the high level stored at the second terminal D of the first latch 14 last time, and the high level is converted to a low level by the inverter 16 and input to the second terminal D of the first latch 14; the first terminal C1 of the second latch 15 receives a high level, the second terminal D of the second latch 15 receives a high level outputted from the third terminal Q of the first latch 14, and the third terminal Q of the second latch 15 outputs a low level stored at the second terminal D of the second latch 15 last time;
when the count signal rises to the high level for the third time, the first terminal C1 of the first latch 14 receives the high level, and the third terminal Q of the first latch 14 outputs the low level stored at the second terminal D of the first latch 14 last time, and is changed to the high level by the inverter 16 and input to the second terminal D of the first latch 14; the first terminal C1 of the second latch 15 receives a high level, the second terminal D of the second latch 15 receives a low level output from the third terminal Q of the first latch 14, the third terminal Q of the second latch 15 outputs a high level stored in the second terminal D of the second latch 15 last time, at this time, the first switch unit 17 is turned off, the second switch unit 18 is turned on to output the ground signal to the processor 19 as the reset signal, and thus the processor 19 resets the position of the initial display frame 1a after every 3 times of the entire movement of the initial display frame 1a is completed.
In this embodiment, the display panel 1 further includes a current limiting resistor R for preventing an excessive current from breaking down the first switch unit 17 under the loading of the first voltage signal.
It can be understood that, in the present embodiment, by moving the initial display screen 1a as a whole, the pixel units 11 in the display panel 1 can be prevented from displaying the same brightness for a long time, so that the blue sub-pixels in the pixel units 11 are prevented from operating for a long time, and the service life of the blue sub-pixels is improved. Meanwhile, as the initial display picture 1a moves integrally, the change of the display picture cannot be easily perceived by naked eyes of people, and the use experience of the display panel 1 is ensured. After the initial display picture 1a is displaced for a certain number of times, the position of the initial display picture 1a is reset, so that unnecessary power consumption waste caused by the fact that the display picture is replaced all the time can be avoided.
