Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, are intended to fall within the scope of the present application.
The application provides a display picture adjusting method, which is applied to a display panel 1, please refer to fig. 1 and fig. 2 together, fig. 1 is a flow chart of a display picture adjusting method according to an embodiment of the application; fig. 2 is a schematic top view of a display panel according to an embodiment of the application. The display screen adjusting method comprises the following steps: steps S101, S102, S103, S104, S105, wherein the steps S101, S102, S103, S104, S105 are described in detail below.
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 rest time of the display picture of each detection area without change;
s104, judging the relation between the rest time and a first preset threshold value;
and when the rest time is smaller than a first preset threshold value, S105, controlling the whole initial display picture to be displaced 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 enclosed in the display area 1c, a plurality of pixel units 11, a plurality of driving signal lines 12 and a plurality of data signal lines 13 distributed in an array are disposed in the display area 1c, and the corresponding pixel units 11 receive the data signals transmitted by the data signal lines 13 under the excitation of the 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 the 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 is understood that the greater the charging current provided to the color sub-pixel 111 under the loading of the data signal, the greater the light emitting brightness of the color sub-pixel 111, and the lower the light emitting efficiency of the blue color sub-pixel 111, the greater the current required to achieve the same light emitting brightness as the red and green color sub-pixels 111.
It will be understood that the display panel 1 generally includes an effective display area and a reserved display area, and in this embodiment, even when the display panel 1 performs "full screen display", the initial display screen 1a does not fully occupy the entire display area 1c, in other words, when the display panel 1 displays the initial display screen 1a, some of the pixel units 11 do not operate, and the display of the initial display screen 1a is not affected, and in general, the pixel units 11 for displaying the initial display screen 1a are adjacent to the pixel units 11 that do not operate at least in a certain direction. In the present embodiment, the pixel unit 11 for displaying the initial display screen 1a is adjacent to the pixel unit 11 that is not operated in the first direction D1. Accordingly, the displacement of the entire initial display screen 1a in the first direction D1 or the direction opposite to the first direction D1 can be controlled.
Specifically, before controlling the overall displacement of the initial display screen 1a, step S103 and step S104 calculate the rest time and determine the relationship between the rest 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, the first preset threshold is 10 seconds, that is, the time when the display screen in the detection area 1b is unchanged exceeds 10 seconds, and the display screen in the detection area 1b is determined to be stationary, otherwise, it is determined to be dynamic. It will be appreciated that in other possible embodiments, the first preset threshold may be other values, which the present application is not limited to.
It will be appreciated that for a still display, the display brightness may be high, and the corresponding current provided by the data signal to the pixel unit 11 is also high, which easily causes the pixel unit 11 in the detection area 1b to generate too high heat, and affects the lifetime of the pixel unit 11. Therefore, in the present embodiment, before the initial display screen 1a is controlled to be 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 detection area 1b, and if the display screen in the detection area 1b is stationary, it is necessary to reduce the display brightness of the pixel unit 11 in the detection area 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 the first direction D1 or a direction opposite to the first direction D1.
It can be appreciated that in the present embodiment, by moving the whole initial display screen 1a, the pixel unit 11 in the display panel 1 can be prevented from displaying the same brightness for a long time, so that the blue sub-pixel in the pixel unit 11 is prevented from operating for a long time, and the service life of the blue sub-pixel is improved. Meanwhile, the initial display screen 1a moves integrally, so that the change of the display screen cannot be easily perceived by naked eyes of a person, and the use experience of the display panel 1 is ensured.
In one possible embodiment, referring to fig. 1 again, the display screen adjustment method further includes: steps S106 and S107, wherein the steps S106 and S107 are described in detail below.
When the rest time is greater than or equal to the first preset threshold, S106, calculating an 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 brightness is smaller than a second preset threshold, S105, the initial display screen 1a is controlled to be displaced in the first direction D1 or a direction opposite to the first direction D1 as a whole.
In this embodiment, when the rest time is greater than or equal to the first preset threshold, it is determined that the display screen in the detection area 1b is stationary, and step S106 calculates an average value of the display brightness of each pixel unit 11 in the detection area 1b, so as to obtain the average display brightness. When the average display brightness is smaller than the second preset threshold, it is indicated 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 adjustment of the display brightness of the pixel units 11 is not needed. Specifically, the second preset threshold is 75% of the target gray-scale brightness of the detection area 1b, and the target gray-scale brightness may be set according to the pixel unit 11, the circuit, and the like of the display panel 1.
It can be understood that the display brightness of the pixel unit 11 may be calculated by the magnitude of the current value for charging the pixel unit 11, or may be calculated by other manners, and the second preset threshold may also be another value, which is not limited by the present application.
In one possible embodiment, referring to fig. 1 again, the display screen adjustment 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 less than the second preset threshold.
In this embodiment, when the average display brightness is greater than or equal to the second preset threshold, it is indicated that the average display brightness of the pixel units 11 in the detection area 1b is too high, which is easy to cause heat generation of the pixel units 11 and affects the service life of the pixel units 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 1b.
It will be appreciated that in other possible embodiments, the third preset threshold may be other values, as long as it does not affect that the third preset threshold is smaller than the second preset threshold, which the present application is not limited to.
In one possible embodiment, please refer to fig. 3, fig. 3 is a schematic top view of a display panel according to another embodiment of the present application. 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, the initial display screen 1a is located in the first display area 1e, and the step of controlling the displacement of the entire initial display screen 1a in the first direction D1 or in a direction opposite to the first direction D1 specifically includes:
controlling the whole initial display picture 1a to be shifted to the second display area 1f at least partially; or alternatively, the process may be performed,
the whole display screen after the control displacement is displaced at least partially to 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 the descriptions of the effective detection area 1b and the reserved detection area 1b are referred to above and are 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 entire initial display screen 1a can be controlled to be displaced at least partially toward the second display area 1 f. It can be understood that, in this embodiment, after the initial display screen 1a is displaced toward the second display area 1f at least partially, a portion of the pixel unit 11 on a side of the first display area 1e facing away from the second display area 1f is put into an inactive state from an active state, in other words, a portion of the first display area 1e facing away from the second display area 1f is changed from the effective detection area 1b to the reserved detection area 1b. Therefore, the whole shifted display frame can be controlled to be shifted to at least a part of the first display area 1e, that is, only a small part of the second display area 1f needs to be reserved, so that the initial display frame 1a can be shifted in the first direction D1 in multiple manners, thereby achieving the purpose of prolonging the service life of the blue sub-pixels in the pixel unit 11.
For example, the initial display 1a may be controlled to be displaced by one unit toward the second display area 1f, and then the initial display 1a may be controlled to be displaced by one unit toward the first display area 1e, so that the above steps are repeated; alternatively, the whole initial display 1a may be controlled to be shifted by one unit toward the second display area 1f, then the whole initial display 1a may be controlled to be shifted by one unit … … toward the first display area 1e, and so on, which is not limited in the present application.
It will be appreciated that, in other possible embodiments, if the display area 1c includes a reserved display area in the second direction D2, the entire initial display screen 1a may be controlled to be displaced in the second direction D2 or a direction opposite to the second direction D2, which is not limited in the present application.
It can be understood that, in order to prevent the problem of the ghost image of the display screen, after the initial display screen 1a is displaced, at least a certain time is required before the next displacement, and the interval time should be greater than the first preset threshold, otherwise, before judging whether the display screen of the detection area 1b is stationary, the displacement of the initial display screen 1a is performed.
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 to be greater than the first preset threshold value, which is not limited by the present application.
In one possible embodiment, please refer to fig. 4, fig. 4 is a schematic diagram of dividing displacement units according to an embodiment of the present application. The display screen adjusting method further comprises the following steps:
dividing the display area 1c into n displacement units 1g extending in the second direction D2; wherein the second direction D2 is perpendicular to the first direction D1, and n is a positive integer;
the step of controlling the displacement of the whole initial display screen 1a to the second display area 1f at least partially specifically includes:
traversing the i displacement units 1g, and replacing the display picture of the i displacement unit 1g to the display picture of the i+1th displacement unit 1g;
the step of controlling the whole displaced display screen to be displaced at least partially toward the first display area 1e specifically includes:
traversing the i displacement units 1g, and replacing the display picture of the i displacement unit 1g to the display picture of the i-1 displacement unit 1g;
wherein i is a positive integer, and 0< i < n.
In this embodiment, as shown in fig. 4, the boundary between the two displacement units 1g coincides with the boundary between the first display area 1e and the second display area 1 f. It will be appreciated that traversing i of said displacement units 1g means taking a value of i in the range of positive integer values from 1 to n-1. Instead of n displacement units 1g, i displacement units 1g may be traversed, because in the first direction D1, the displacement unit 1g located at the boundary of the first display area 1e on the side 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 replaceable displacement unit 1g during the replacement of the display screen, and therefore, in this embodiment, i displacement units 1g are traversed, so that the rest of the 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 boundary of the second display area 1 f.
It will be appreciated that since the initial display screen 1a is located in the displacement units 1g which are at least partially continuous, the entire displacement of the initial display screen 1a can be achieved by performing replacement of the display screen by traversing i of the displacement units 1g.
Specifically, when the entire initial display screen 1a is controlled to be shifted to the second display area 1f at least partially, the display screen of the i-th shift unit 1g is replaced to the display screen of the i+1th shift unit 1g by traversing the i-th shift units 1g, so that the entire initial display screen 1a is shifted to the second display area 1f by one shift unit 1g.
It will be appreciated that, when the initial display 1a is shifted by one of the shift units 1g toward the second display area 1f as a whole, the initial display 1a is not adjacent to the boundary of the first display area 1e in the first direction D1, and therefore, after the shifting of the entire display to the first display area 1e is controlled at least partially, the shifting of the entire display 1a by one of the shift units 1g toward the first display area 1e can be achieved by shifting the display 1a of the i-th shift unit 1g to the display 1g of the i-1 th shift unit 1g through i-th shift unit 1g.
In one possible embodiment, please refer to fig. 5, fig. 5 is a partially enlarged schematic diagram of a display panel according to an embodiment of the application. The display panel 1 comprises a plurality of pixel units 11 distributed in an array, and the 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 columns of the pixel units 11 that are continuous in the first direction D1, the display screen of the i-th displacement unit 1g is replaced with the display screen of the i+1th displacement unit 1g, which may be that the display screen of the 1 st column of the pixel units 11 is replaced with the display screen of the 3 rd column of the pixel units 11, and the display screen of the 2 nd column of the pixel units 11 is replaced with the display screen of the 4 th column of the pixel units 11; the display screen of the pixel unit 11 of the 3 rd column is replaced with the display screen of the pixel unit 11 of the 5 th column, the display screen of the pixel unit 11 of the 4 th column is replaced with the display screen … … of the pixel unit 11 of the 6 th column, and so on.
It will be appreciated that in order to avoid that the displacement of the initial display screen 1a can be easily perceived by the naked human eye, the number of columns of the pixel units 11 to be replaced at one time should not be excessive during each displacement of the initial display screen 1a. In the present embodiment, the orthographic projection of the displacement unit 1g on the display panel 1 covers 1-3 columns of the pixel units 11 continuous in the first direction D1.
In a possible embodiment, 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 screen of the i-th displacement unit 1g with the display screen of the i+1th displacement unit 1g specifically includes:
acquiring a data signal transmitted on the data signal line 13 correspondingly arranged on the ith displacement unit 1g;
transmitting the data signals to the data signal lines 13 provided corresponding to the (i+1) th displacement units 1g, respectively;
the step of replacing the display screen of the i-th displacement unit 1g to the display screen of the i-1 th displacement unit 1g specifically comprises the following steps:
acquiring a data signal transmitted on the data signal line 13 correspondingly arranged on the ith displacement unit 1g;
the data signals are transmitted to the data signal lines 13 provided corresponding to the i-1 th displacement units 1g, respectively.
It is understood that there are various ways of controlling the displacement of the whole initial display screen 1a in the first direction D1 or the direction opposite to the first direction D1, for example, changing the driving signal corresponding to the driving signal line 12 or changing the data signal corresponding to the data signal line 13 may be implemented.
In general, the voltage value of the driving signal is high, and by switching the high and low levels of the driving signal, the initial display screen 1a is controlled to be displaced in the first direction D1 or the direction opposite to the first direction D1, which results in high power consumption. In contrast, 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 shifting can be saved.
In one possible embodiment, referring to fig. 1 again, the display screen adjustment method further includes: step S109, wherein the detailed description of step S109 is 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 larger than or equal to the preset number of times, restoring the initial display picture 1a to the initial position.
It should be noted that, as shown in fig. 1, when the number of times of displacement of the initial display screen 1a is smaller than the preset number of times, the initial display screen 1a is still displaced at intervals. Specifically, after the number of times of displacement of the initial display screen 1a is greater than or equal to the preset number of times, the initial display screen 1a is restored to the initial position, in this embodiment, the initial display screen 1a is restored to the corresponding first display area 1 e. It can be understood that, after the initial display screen 1a is shifted for a certain number of times, the position of the initial display screen 1a is reset, so that the replacement of the display screen is always performed, and unnecessary power consumption waste is avoided.
In this embodiment, the preset number of times is 3. It will be appreciated that in other possible embodiments, the preset number of times may be other values, which the present application is not limited to.

Each time the initial display 1a moves as a whole, the count signal received by the first latch 14 generates a rising edge, i.e., the count signal transitions from a low level to a high level signal. 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 a high level for the first time, the first terminal C1 of the first latch 14 receives the high level, the third terminal Q of the first latch 14 outputs a low level, and is converted to a high level through 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 of the third terminal Q output of the first latch 14, and the third terminal Q output of the second latch 15 is still a low level;
