When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure.

For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Firstly, the application scene related to the invention is introduced:
as shown in fig. 2, in order to improve the abnormal crosstalk of the display panel with the normal architecture, a Z-type architecture as shown in fig. 1 is selected and used, where DR1 in fig. 1 is a signal line for outputting valid data, two sides of DR1 signal line are respectively connected to pixel driving circuits (at the square frame at two sides of the signal line in fig. 1), each pixel driving circuit controls the corresponding pixel to display, and the left and right sides of DR1 signal line are alternately connected to the pixel driving circuits. The 2 nd and 4 th pixel positions on the right side of the DR1 from top to bottom are supplemented with partial pixels missing from the DR1 through a Dummy signal line, but the Dummy signal line does not output valid data, so that a voltage difference exists between the Dummy signal line and a DR1 signal line outputting valid data, the display brightness of the first column of pixels on the right side is inconsistent, the picture display is abnormal, and the 2 nd and 4 th pixel positions and the 1 st and 3 rd pixel positions have different brightness.
The method provided by the embodiment of the invention is applied to the display equipment, and is used for processing the data of the DR1 and the Dummy signal line so as to solve the problem of inconsistent display brightness.
The inventive concept of the method of the embodiment of the invention is as follows: because the DR1 signal line and the Dummy signal line have voltage difference due to data inconsistency, the DR1 signal line and the Dummy signal line can be input with the same data signal, and the DR1 signal line can be input with the Dummy signal line, so as to solve the problem of inconsistent display brightness.
In other embodiments, in order to be compatible with the normal architecture, the method may be performed without increasing power consumption under the normal architecture, in which the display panel is determined to be the Z-type architecture, and output is normally performed under the normal architecture.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 3 is a schematic flowchart of a signal processing method according to an embodiment of the present invention. As shown in fig. 3, the method provided in this embodiment may be applied to a display device, a display panel of the display device is a zigzag structure, the display panel includes a first signal line and a second signal line, two sides of the first signal line are respectively and alternately connected to a first pixel driving circuit, and one side of the second signal line close to the first signal line is connected to a second pixel driving circuit, and the method includes:
step 101, acquiring first data to be input to a first signal line and second data to be input to a second signal line;
specifically, as shown in fig. 1, the first signal line is a DR1 signal line, the second signal line is a Dummy signal line, the pixel driving circuits are alternately connected to both sides of the DR1 signal line, the 2 nd and 4 th pixel positions from top to bottom on the right side of DR1 are supplemented by one Dummy signal line for the missing part of pixels of DR1, but valid data is not output by the Dummy signal line, so that a voltage difference exists between the signal of the Dummy signal line and the signal of DR1 outputting valid data, which causes inconsistent display brightness of the first column of pixels on the right side in fig. 1, and abnormal image display occurs.
In the method of the embodiment, first data to be input to the first signal line and second data to be input to the second signal line are acquired. If the difference between the first data and the second data is larger, a predetermined condition is satisfied, for example, the check values are different, or the distance is larger, and the distance may be, for example, a euclidean distance. If the difference between the first data to be input to the first signal line and the second data to be input to the second signal line is large, that is, there is a voltage difference between the signal of the first data and the signal of the second data, and if there is a voltage difference, the display brightness of the pixels in the first row on the right side in fig. 1 may be inconsistent.
And 102, if the difference between the first data and the second data meets a preset condition, inputting a signal of the first data to the first signal line and the second signal line respectively so that the first signal line controls the pixel display corresponding to the first pixel driving circuit, and the second signal line controls the pixel display corresponding to the second pixel driving circuit.
Specifically, in step 101, it is determined that a difference between first data to be input to the first signal line and second data to be input to the second signal line satisfies a preset condition, and if a signal of the first data and a signal of the second data are respectively input to the first signal line and the second signal line, a voltage difference may exist between the first signal line and the second signal line, and if the voltage difference exists, display luminance of pixels in a first column on the right side in fig. 1 may be inconsistent. In order to reduce the display brightness inconsistency, the same data can be input to the first signal line and the second signal line, and since the first data is effective data, the first signal line and the second signal line can be respectively input with the signal of the first data, the pixel display corresponding to the first pixel driving circuit is controlled by the first signal line, and the pixel display corresponding to the second pixel driving circuit is controlled by the second signal line. Finally, the data input by the first signal line and the second signal line are the same, so that the situation that the display brightness of the pixels in the first column on the right side in the figure 1 is inconsistent is avoided.
According to the method, the display panel of the display device is of a Z-shaped structure and comprises a first signal line and a second signal line, the two sides of the first signal line are respectively and alternately connected with a first pixel driving circuit, the second signal line is connected with a second pixel driving circuit at one side close to the first signal line, and finally, when the difference of data to be input of the first signal line and the second signal line is large, the data input to the first signal line and the data input to the second signal line are the same, so that the display brightness consistency of pixels between the DR1 signal line and the Dummy signal line is realized, the viewing experience of a user is improved, and the problems of inconsistent display brightness and abnormal picture display of the pixels between the DR1 signal line and the Dummy signal line are solved.
On the basis of the above embodiment, it may be determined whether the difference between the first data and the second data satisfies the preset condition in several ways:
one implementation is as follows:
acquiring a check value of the first data and a check value of the second data;
and if the check value of the first data is different from the check value of the second data, determining that the difference between the first data and the second data meets a preset condition.
Specifically, the check value of the first data may be used to identify the first data, the check value of the second data may be used to identify the second data, and then it may be determined whether a difference between the first data to be input to the first signal line and the second data to be input to the second signal line satisfies a preset condition, that is, whether a voltage difference exists between a signal of the first data and a signal of the second data, where if the voltage difference exists, it is described that display luminance of the first column of pixels on the right side in fig. 1 may be inconsistent. And if the check value of the first data is different from the check value of the second data, determining that the difference between the first data and the second data meets a preset condition.
The check value can be obtained by the following method:
acquiring a check value of the first data by using an accumulation and check Checksum algorithm;
and acquiring a check value of the second data by using a Checksum algorithm.
In other embodiments of the present invention, the check value may also be obtained in other manners, such as MD5, which is not limited in this embodiment of the present invention.
The check value can be calculated by the timing controller, and in actual operation, only a part of data to be input to the first signal line can be acquired and compared with a part of data to be input to the second signal line without performing comparison with the entire first data. That is, only the check value of the partial data to be input to the first signal line is acquired.
For example, the first data is pixel data of a certain video, the first frame pixel data of the video to be displayed may be selected.
The other realization mode is as follows:
determining the Euclidean distance between the first data and the second data;
and if the Euclidean distance between the first data and the second data is larger than a preset threshold value, determining that the difference between the first data and the second data meets a preset condition.
Specifically, it is determined whether the difference between the first data and the second data meets a preset condition by calculating a euclidean distance between the first data and the second data, and if the euclidean distance is greater than a preset threshold, that is, it indicates that the difference between the first data and the second data is large, it is determined that the difference between the first data and the second data meets the preset condition.
In other embodiments, for example, hash values of the first data and the second data may also be determined, and if the hash values of the first data and the second data are different, it is determined that the difference between the first data and the second data satisfies a preset condition, that is, it is determined that the first data and the second data are different, which is not limited in this embodiment of the present application.
In the above specific embodiment, whether a difference between first data to be input to the first signal line and second data to be input to the second signal line satisfies a preset condition may be determined by calculating a check value or a euclidean distance, which is simple to implement and high in efficiency.
In one embodiment, acquiring first data to be input to the first signal line and second data to be input to the second signal line includes:
acquiring first (V-by-One, VBO) data to be input to the first signal line, and converting the first VBO data into the first data;
and acquiring second VBO data to be input to the second signal line, and converting the second VBO data into the second data.
The TCON takes VBO data from the SOC.
VBO is a signal transmission interface standard suitable for flat panel displays. The first data may be data in a Mini Low-Voltage Differential Signaling (Mini-LVDS) format or a (Point-Point) P-P format, and the second data may be data in a Mini-LVDS format or a P-P format. The Mini-LVDS is an interface for connecting the timing controller and the column driver (i.e., the source driver in the source chip), and the Mini-LVDS interface is unidirectional, and data can only be transferred from the timing control chip to the column driver.
In one embodiment, inputting signals of first data to the first signal line and the second signal line, respectively, includes:
after the signal of the first data is amplified, the signal is input to the first signal line and the second signal line.
Specifically, as shown in fig. 5, before the signal of the first data is input to the first signal line and the second signal line, the signal of the first data is amplified, for example, by a driver in the source chip, so as to control the first pixel driving circuit connected to the first signal line and the second pixel driving circuit connected to the second signal line, the first signal line controls the pixel display corresponding to the first pixel driving circuit, and the second signal line controls the pixel display corresponding to the second pixel driving circuit.
And amplifying the signal of the first data and then driving a second pixel driving circuit to ensure normal pixel display.
Because the signals of the data input by the first signal line and the second signal line are the same, no pressure difference exists, and the condition that the display brightness of the pixels between the first signal line and the second signal line is inconsistent is avoided.
In this embodiment, when the difference between the data to be input to the first signal line and the data to be input to the second signal line is large, the data finally input to the first signal line and the data finally input to the second signal line are the same, so that the display brightness consistency of the pixels between the DR1 signal line and the Dummy signal line is realized, the viewing experience of a user is improved, and the problems of inconsistent display brightness of the pixels between the DR1 signal line and the Dummy signal line and abnormal picture display are avoided.
Fig. 4 is a structural diagram of an embodiment of a display device provided in the present invention, and as shown in fig. 4, the display device of the embodiment includes:
a processor 401 and a display panel 402;
the display panel is of a Z-shaped structure and comprises a first signal line and a second signal line; two sides of the first signal line are respectively connected with a first pixel driving circuit, and one side of the second signal line close to the first signal line is connected with a second pixel driving circuit;

if the difference between the first data and the second data meets a preset condition, inputting the signal of the first data to the first signal line and the second signal line respectively;
the first signal line is used for controlling the pixel display corresponding to the first pixel driving circuit according to the signal of the first data, and the second signal line is used for controlling the pixel display corresponding to the second pixel driving circuit according to the signal of the first data.
Specifically, as shown in fig. 1, the first signal line is a DR1 signal line, the second signal line is a Dummy signal line, the pixel driving circuits are alternately connected to both sides of the DR1 signal line, the 2 nd and 4 th pixel positions from top to bottom on the right side of DR1 are supplemented by one Dummy signal line for the missing part of pixels of DR1, but valid data is not output by the Dummy signal line, so that a voltage difference exists between the signal of the Dummy signal line and the signal of DR1 outputting valid data, which causes inconsistent display brightness of the first column of pixels on the right side in fig. 1, and abnormal image display occurs.
Therefore, in this embodiment, the first data to be input to the first signal line and the second data to be input to the second signal line are obtained, if the difference between the first data and the second data is large, a predetermined condition is satisfied, for example, the check values are different, or the distance is large, where the distance may be, for example, a euclidean distance, if the difference between the first data to be input to the first signal line and the second data to be input to the second signal line is large, that is, there is a difference between the signal of the first data and the signal of the second data, and if there is a difference, the display brightness of the first row of pixels on the right side in fig. 1 may be inconsistent.
In order to reduce the display brightness inconsistency, the same data can be input to the first signal line and the second signal line, and the first data is effective data, the first signal line and the second signal line can be respectively input with the signal of the first data, the first signal line controls the pixel display corresponding to the first pixel driving circuit, and the second signal line controls the pixel display corresponding to the second pixel driving circuit. Finally, the data input by the first signal line and the second signal line are the same, so that the situation that the display brightness of the pixels in the first column on the right side in the figure 1 is inconsistent is avoided.
In one embodiment, as shown in fig. 5, the processor may be a timing controller Tcon. The signal source is provided by a system-on-chip SOC, the SOC outputs VBO data to a Tcon, the Tcon converts first VBO data to be input to a first signal line into first data, and converts second VBO data to be input to a second signal line into second data.
If the difference between the first data and the second data meets the preset condition, inputting the first data to a source chip by the Tcon; and the source chip (source IC) is used for amplifying the signal of the first data and then respectively inputting the amplified signal to the first signal line and the second signal line of the display panel.
And the source chip is further used for performing digital-to-analog conversion on the signals of the first data before the signals of the first data are amplified and then are respectively input to the first signal line and the second signal line.
In an embodiment, the processor 401 is specifically configured to:
acquiring a check value of the first data and a check value of the second data;
and if the check value of the first data is different from the check value of the second data, determining that the difference between the first data and the second data meets a preset condition.
In an embodiment, the processor 401 is specifically configured to:
acquiring a check value of the first data by using an accumulation and check Checksum algorithm;
and acquiring a check value of the second data by using a Checksum algorithm.

and if the Euclidean distance between the first data and the second data is larger than a preset threshold value, determining that the difference between the first data and the second data meets a preset condition.
In an embodiment, as shown in fig. 5 and 6, when the device is started, a Tcon receives VBO data, where the VBO data is to be input to each signal line, and the Tcon converts the VBO data into data in a Mini-LVDS/P-P format, determines whether a current display panel is in a Z-type architecture, and if the current display panel is in the Z-type architecture, acquires a check value of first data to be input to a first signal line and a check value of second data to be input to a second signal line; comparing whether the check value of the first data is consistent with the check value of the second data; if the check value of the first data is the same as the check value of the second data, setting the data to be input to the second signal line to be consistent with the first data to be input to the first signal line, inputting the first data to the source IC, and further inputting the signals of the first data to the first signal line and the second signal line respectively for normal display; if the structure is not Z-shaped, the data is input to the source IC, and then the data is input to each signal line for normal display; if the structure is not Z-type, the data is input to the source IC, and then the data is input to each signal line for normal display.
In this manner, the source chip outputs the same data to the first signal line and the second signal line (i.e., DR1 signal line and Dummy signal line), and the corresponding source chip also needs to amplify the Dummy signal line, so that the driving is increased and the power consumption is increased; in order to ensure that power consumption is not increased under normal output, in the above embodiment, the timing controller needs to make different settings for the Z-type architecture and the non-Z-type architecture, which not only ensures that signals of data input by the Dummy signal line and the DR1 signal line under the Z-type architecture are the same, but also ensures that power consumption is not increased under the non-Z-type architecture.
