First, an application scenario related to the present application is described:
as shown in fig. 2, in order to improve the crosstalk anomaly of the picture, a Z-type structure as shown in fig. 1 is selected for use, DR1 in fig. 1 is a signal line for outputting effective data, two sides of the DR1 signal line are respectively connected to pixel driving circuits (at the boxes on 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 the DR1 signal line are alternately connected to the pixel driving circuits. The 2 nd and 4 th pixel positions on the right side of DR1 from top to bottom supplement part of the pixels missing from DR1 through a Dummy signal line, but the Dummy signal line does not output effective data, so that the Dummy signal line and the DR1 signal line outputting effective data have a voltage difference, the display brightness of the first column pixel on the right side is inconsistent, the picture displays abnormally, and the brightness displayed by the 2 nd and 4 th pixel positions and the 1 st and 3 rd pixel positions are different.
The method provided by the embodiment of the application is applied to the display equipment to process the data of the DR1 and Dummy signal wires so as to solve the problem of inconsistent display brightness.
The inventive concept of the method of the embodiment of the application is as follows: since the DR1 signal line and the Dummy signal line have a voltage difference due to data inconsistency, a signal having the same data can be input to the DR1 signal line and the Dummy signal line, and a signal having the data of the DR1 signal line can be input to the Dummy signal line, thereby solving the problem of inconsistent display brightness.
In other embodiments, in order to be compatible with the normal architecture, the power consumption in the normal architecture is not increased, and the method may be performed in a case where it is determined that the display panel is of the Z-type architecture, where the normal output is performed.
The technical scheme of the application is described in detail below by specific examples. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.
Fig. 3 is a flowchart of an embodiment of a signal processing method according to the present application. As shown in fig. 3, the method provided in this embodiment may be applied to a display device, where a display panel of the display device is a Z-shaped structure, the display panel includes a first signal line and a second signal line, two sides of the first signal line are alternately 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, where 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, two sides of the DR1 signal line are alternately connected to the pixel driving circuits, and the 2 nd and 4 th pixel positions on the right side of DR1 are complemented by one Dummy signal line from top to bottom, but the Dummy signal line does not output valid data, so that a voltage difference exists between signals of the Dummy signal line and the DR1 signal line outputting valid data, resulting in inconsistent display brightness and abnormal display of the first column pixels on the right side in fig. 1.
In the method of the present embodiment, first data to be input to a first signal line and second data to be input to a second signal line are acquired. If the difference between the first data and the second data is large, a preset condition is satisfied, for example, the check values are different, or the distance is large, where the distance may be, for example, the 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, if there is a voltage difference between the first data signal and the second data signal, the display brightness of the pixels in the first row on the right side in fig. 1 will be inconsistent.
Step 102, if the difference between the first data and the second data meets the preset condition, inputting the signals 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 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 satisfies the preset condition, if the signals of the first data and the second data are input to the first signal line and the second signal line respectively, there is a differential pressure between the first signal line and the second signal line, and if there is a differential pressure, there is an inconsistency in the display brightness of the pixels in the first column on the right side in fig. 1. In order to reduce display luminance inconsistency, the same data may be input to the first signal line and the second signal line, and since the first data is valid data, the first signal line and the second signal line may be respectively input with signals of the first data, the first signal line may control the pixel display corresponding to the first pixel driving circuit, and the second signal line may control the pixel display corresponding to the second pixel driving circuit. Finally, since the data input by the first signal line and the second signal line are the same, the situation that the display brightness of the pixels in the first column on the right side in fig. 1 is inconsistent is avoided.
According to the method, the display panel of the display device is of a Z-shaped structure, the display panel comprises a first signal line and a second signal line, the two sides of the first signal line are alternately connected with a first pixel driving circuit respectively, the second signal line is alternately connected with a second pixel driving circuit at one side close to the first signal line, and when the difference of data to be input by the first signal line and the second signal line is large, the data finally input to the first signal line and the second signal line are identical, so that the consistency of the display brightness of pixels between a DR1 signal line and a Dummy signal line is realized, the user watching experience is improved, the problem that the display brightness of pixels between the DR1 signal line and the Dummy signal line is inconsistent, and the problem of abnormal picture display is avoided.
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:
acquiring a check value of the first data and a check value of the second data;
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 whether 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 meets a preset condition or not may be determined according to the check value of the first data and the check value of the second data, that is, whether a differential pressure exists between the signal of the first data and the signal of the second data or not, if the differential pressure exists, it is indicated that the display brightness of the pixels in the first column on the right side in fig. 1 may be inconsistent. 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 the preset condition.
Wherein, the check value can be obtained by the following way:
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 application, the check value may be obtained by other manners, such as MD5, which is not limited in this embodiment of the present application.
The verification value may be calculated by the timing controller, and in actual operation, only the partial data to be input to the first signal line may be acquired, compared with the partial data to be input to the second signal line, without comparing with the entire first data. I.e. only the check value of the part of the data to be input to the first signal line is acquired.
For example, the first data is the pixel data of a certain video, then the first frame of pixel data of the video to be displayed may be selected.
Another implementation:
determining Euclidean distance between the first data and the second data;
if the Euclidean distance between the first data and the second data is larger than the preset threshold value, determining that the difference between the first data and the second data meets the preset condition.
Specifically, by calculating the Euclidean distance between the first data and the second data, whether the difference between the first data and the second data meets the preset condition is determined, if the Euclidean distance is larger than the preset threshold, that is, the difference between the first data and the second data is larger is indicated, and if the difference between the first data and the second data is larger, the difference between the first data and the second data is determined to meet the preset condition.
In other embodiments, for example, hash values of the first data and the second data may 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 meets a preset condition, that is, it is determined that the first data and the second data are different, which is not limited by the embodiment of the present application.
In the above embodiment, whether 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 meets the preset condition may be determined by calculating the check value or the euclidean distance, which is simple to implement and has higher efficiency.
In an embodiment, acquiring the first data to be input to the first signal line and the 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.
TCON obtains VBO data from SOC.
The VBO is a signal transmission interface standard suitable for a flat panel display. The first data may be data in a Low voltage differential signaling (Mini Low-Voltage Differential Signaling, mini-LVDS) format or a (Point-Point) P-P format of the high-speed serial interface, and the second data may be data in a Mini-LVDS format or a P-P format. Mini-LVDS is an interface that connects a timing controller with a column driver (i.e., a source driver in a source chip), and the Mini-LVDS interface is unidirectional, with data only passing from the timing controller chip to the column driver.
In one embodiment, inputting signals of first data to a first signal line and a second signal line, respectively, includes:
the signal of the first data is amplified and then 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 realize control of the first signal line over the connected first pixel driving circuit, control of the second signal line over the connected second pixel driving circuit, where 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 to drive the second pixel driving circuit so as to ensure normal pixel display.
Since the signals of the data input by the first signal line and the second signal line are the same, there is no voltage difference, and the situation that the display brightness of the pixels between the first signal line and the second signal line is not uniform is avoided.
In this embodiment, when the difference between the data to be input by the first signal line and the second signal line is large, the data finally input to the first signal line and the second signal line are the same, so that the display brightness of the pixels between the DR1 signal line and the Dummy signal line is consistent, the user viewing experience is improved, and the problems of inconsistent display brightness of the pixels between the DR1 signal line and the Dummy signal line and abnormal display of the picture are avoided.
Fig. 4 is a block diagram of an embodiment of a display device according to the present application, as shown in fig. 4, where the display device according to the present embodiment includes:

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, the preset conditions are satisfied, for example, the check values are different, or the distances are large, where the distances may be, for example, euclidean distances, and 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, the difference between the signals of the first data and the second data exists, and if the difference exists, the display brightness of the pixels in the first row on the right side in fig. 1 may be inconsistent.
In order to reduce display luminance inconsistency, the same data may be input to the first signal line and the second signal line, and since the first data is valid data, the first signal line and the second signal line may be respectively input with signals of the first data, the first signal line controls pixel display corresponding to the first pixel driving circuit, and the second signal line controls pixel display corresponding to the second pixel driving circuit. Finally, since the data input by the first signal line and the second signal line are the same, the situation that the display brightness of the pixels in the first column on the right side in fig. 1 is inconsistent is avoided.

In one embodiment, the processor 401 is specifically configured to:

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 driving is increased and power consumption is increased; in order to ensure that the 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, so that the same signals of the data input by the Dummy signal line and the DR1 signal line under the Z-type architecture are ensured, and the power consumption is not increased under the non-Z-type architecture.
