Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
The embodiment of the present application provides a display panel, as shown in fig. 1, the display panel includes a display driver chip 10 and a display unit 20, the display unit 20 includes a plurality of charging lines 2011, each charging line is connected with a plurality of sub-pixels 2012, the display driver chip 10 is electrically connected to each charging line 2011, each charging line corresponds to a line identifier, for example, when there are n charging lines, the n charging lines may be respectively identified as 1 to n, then each connected sub-pixel may also have a corresponding identifier and also have a line identifier of the charging line connected thereto, for example, the identifier of the 1 st sub-pixel on the 1 st charging line may be 1 to 2, and the identifier of the 5 th sub-pixel on the 2 nd charging record may be 2 to 5, and so on; in addition, the display panel of the present application further includes a frame memory 30, and the frame memory 30 is used for transmitting the picture information to be displayed to the display driving chip 10.
On the basis of the display panel designed above, an embodiment of the present invention provides a data processing method for a display panel, which is applied to the display driver chip, as shown in fig. 2, and the method specifically includes the following steps:
step S100: and determining the pixel value of each sub-pixel in the current frame according to the target image to be displayed.
Step S102: and dividing the plurality of charging lines into a first charging line and a second charging line according to the pixel value of each sub-pixel in the current frame, wherein the pixel values of the plurality of sub-pixels connected by the first charging line are all the same and are corresponding target pixel values, and the pixel values of the plurality of sub-pixels connected by the second charging line are not all the same.
Step S104: and associating and storing the line identification of each first charging line with the corresponding target pixel value.
Step S106: and associating the pixel values of the plurality of sub-pixels corresponding to each second charging line with the line identification of the corresponding charging line, and performing compression storage.
In step S100, the target image to be displayed is an image that needs to be displayed, and the image information transmitted according to the received frame memory is the target image to be displayed; after the display driving information obtains the target image to be displayed, the target image to be displayed is processed, specifically, a plurality of pixel points in the target image to be displayed correspond to a plurality of sub-pixels of a plurality of charging lines on the display panel, so that each sub-pixel can represent a pixel point and further display a pixel value of the pixel point, that is, a pixel value of each sub-pixel in the plurality of charging lines in the current frame can be obtained, and then step S102 is executed.
In step S102, the display driver chip divides the plurality of charging lines into two types, i.e., a first charging line and a second charging line, according to the pixel value of each sub-pixel, where the first charging line indicates that the pixel values of all sub-pixels connected by the charging line are all the same, and the second charging line indicates that the pixel values of all sub-pixels connected by the charging line are not all the same, for example, 400 sub-pixels are connected to the 1 st charging line, and when the pixel values of the 400 sub-pixels are all 0, i.e., black, it indicates that the pixel values of the sub-pixels connected by the 1 st charging line are all the same, i.e., the 1 st charging line is the first charging line; if 399 pixel values in the 400 th sub-pixel are all 0, and 1 pixel value in the 400 th sub-pixel is 1, the pixel values of the sub-pixels connected with the 1 st charging line are not all the same, namely the 1 st line is the second charging line; in addition, when there are more than two charging lines as the first charging lines, the pixel values of the sub-pixels connected by the more than two charging lines may be the same or different, for example, it is determined that only the 1 st, 3 rd and 5 th charging lines in the n charging lines are the first charging lines, the pixel values of the sub-pixels connected by the 1 st line are all 0, the pixel values of the sub-pixels connected by the 3 rd line are all 0, and the pixel values of the sub-pixels connected by the 5 th line are also 0, that is, the target pixel values of the different first charging lines are the same; when the pixel values of the sub-pixels connected in the 1 st line are all 0, the pixel values of the sub-pixels connected in the 3 rd line are all 255, and the pixel values of the sub-pixels connected in the 5 th line are all 255, that is, the target pixel values of the different first charging lines are not all the same (may be partially the same).
Specifically, in step S102, a preset target pixel value is used, and then whether the pixel value of each sub-pixel in the plurality of sub-pixels connected to each charging line is the preset target pixel value is determined, when the pixel value of each sub-pixel in the plurality of sub-pixels connected to the charging line is the preset target pixel value, the charging line may be determined as the first charging line; when the pixel value of a certain sub-pixel in the plurality of sub-pixels connected by the charging circuit is not the preset target pixel value, the charging circuit can be determined to be the second charging circuit.
In addition, the foregoing step S102 may be further divided by the following steps, as shown in fig. 3, including:
step S1020: and sequentially counting the pixel values of a plurality of sub-pixels connected with each charging line according to a preset sequence.
Step S1021: and determining a charging line, in which the pixel values of the connected sub-pixels are all the same, as a first charging line.
Step S1022: and determining charging lines, which do not have the same pixel value, of the connected sub-pixels as the second charging lines.
In the above step, after the pixel value corresponding to each sub-pixel is obtained, the pixel values of the plurality of sub-pixels connected to each charging line may be counted sequentially according to a certain order, for example, when the n charging lines having line identifiers 1 to n are described above, the n charging lines may be counted sequentially according to a preset order, for example, the n charging lines may be counted sequentially from the 1 st line to the nth line from the small to the large according to the identifier, or counted sequentially from the nth line to the 1 st line from the large to the small according to the identifier, or counted sequentially from the top to the right according to the position of the charging line, and so on.
Similarly, when the pixel values of the plurality of sub-pixels on one charging line are counted, the pixel values of the plurality of sub-pixels need to be counted according to a certain sequence, for example, the 1 st charging line has k sub-pixels with the identifiers of 1 to k, and the number from the 1 st to the kth or the number from the kth to the 1 st are counted sequentially from the identifiers of 1 from small to large.
On the basis, when the pixel values of a plurality of sub-pixels on a certain charging line are counted, when the pixel values of two sub-pixels are different, the counting of the current charging line can be stopped, and then the counting of the next charging line is performed.
For example, when k sub-pixels on the 1 st charging line are counted, when the pixel values of the 1 st and 2 nd sub-pixels are counted as 0, and when the pixel value of the 3 rd sub-pixel is counted as 1, the counting of the 1 st charging line can be stopped, and then the counting of the 2 nd charging line can be performed.
When the pixel values of a plurality of sub-pixels on a certain charging line are counted, if the counted pixel values of the sub-pixels are the same as the pixel values of the sub-pixels which are counted before, counting is continued until all the sub-pixels of the current charging line are counted, and counting of the next charging line is not performed.
For example, when k sub-pixels on the 1 st charging line are counted, when the pixel values of the 1 st and 2 nd sub-pixels are counted as 0 and the 3 rd sub-pixel is counted, the pixel value of the 3 rd sub-pixel is also 0, then the counting is continued, if a sub-pixel with a pixel value not being 0 subsequently appears, the counting on the 1 st charging line is stopped, and if the pixel values of each sub-pixel are continued to be 0, then the counting on the 2 nd charging line is performed after the counting on the k sub-pixels of the 1 st charging line is completed.
After the plurality of charging lines are divided into the first charging lines and the second charging lines, step S104 may be executed to associate and store the line identifier of each first charging line with the corresponding target pixel value.
Specifically, if the target pixel values of all the first charging lines are all the same, the target pixel value may be associated with and stored in the line identifier corresponding to each first charging line, and it is not necessary to associate a separate target pixel value with each charging line.
If the target pixel values of all the first charging lines are not all the same, associating and storing the line identifier of each charging line with its corresponding target pixel value, so that each charging line is associated with its corresponding target pixel value, for example, on the basis of the foregoing example, if the 1 st charging line is a first charging line whose target pixel value is 0, the 3 rd charging line is also a first charging line whose target pixel value is 255, and the 5 th charging line is also a first charging line whose target pixel value is 255, then associating the line identifier 1 of the 1 st charging line with its target pixel value 0, assuming 1-0; associate line identification 3 of the 3 rd charging line with its target pixel value of 255, 3-255; the line identification 5 of the 5 th charging line is associated with its target pixel value 255, 5-255.
After the line identifier of each first charging line is associated with the corresponding target pixel value and stored in step S104, step S106 may be executed to associate and compress the pixel values of the plurality of sub-pixels corresponding to each second charging line with the line identifier of the corresponding charging line, in this step, the display driving chip may associate and compress and store the pixel value of each sub-pixel of the charging line, where the pixel values of the plurality of connected sub-pixels are not all the same, with the line identifier of the corresponding charging line, and then when the line is subsequently displayed, the display driving chip reads and decompresses to obtain the stored pixel value of each sub-pixel, so as to display the corresponding pixel value of the sub-pixel on the corresponding charging line.
Specifically, a static random access memory is arranged in the display driving chip, the display driving chip compresses the pixel value of each sub-pixel on each charging line belonging to the second charging line and stores the compressed pixel value in the static random access memory, the data stored in the static random access memory is read during subsequent display, the pixel value of each sub-pixel on each charging line belonging to the second charging line is obtained after decompression, and then corresponding pixel value display is performed on the corresponding sub-pixel on the charging line.
In the above designed data processing method for a display panel, the display driver chip determines the pixel value of each sub-pixel connected to a plurality of charging lines in the current frame through the target image to be displayed, and further divides the plurality of charging lines into a first charging line and a second charging line according to the pixel value of each sub-pixel in the current frame, wherein the pixel values of the plurality of sub-pixels are all the same and are corresponding target pixel values, and the pixel values of the plurality of sub-pixels are not all the same, and further associates and stores the line identifier of each first charging line and the corresponding target pixel value, associates and stores the pixel values of the plurality of sub-pixels corresponding to each second charging line and the line identifier of the corresponding charging line, and since the charging line identifier and the corresponding target pixel value are directly associated and stored when the data of the first charging line is stored, therefore, the step of compressing the pixel values of the plurality of sub-pixels belonging to the first charging line is saved, so that the electric quantity loss in the compression process can be saved, the problem that when the display panel only needs to display time and a few patterns at present and the rest of the display panel displays a picture with the same color (such as black), all display data still need to be compressed and stored, so that the display panel can be read and displayed subsequently, the power consumption of the display panel is high in the mode of compressing and storing all the display data, and the power consumption of the display panel is reduced.
In an optional implementation manner of this embodiment, on the basis of the foregoing data processing, the present solution further includes a calling display process for performing data storage in subsequent display, as shown in fig. 4, which specifically includes the following steps:
step S108: and acquiring the line identification of the current charging line.
Step S109: judging whether the current charging circuit is a first charging circuit or a second charging circuit according to the circuit identifier of the current charging circuit, and if the current charging circuit is the first charging circuit, turning to the step S110; if the second charging line is used, the process goes to step S111 to step S113.
Step S110: and controlling all sub-pixels connected with the current charging circuit to display target pixel values associated with the line identification of the current charging circuit.
Step S111: and searching pixel values of a plurality of sub-pixels associated with the line identification stored in a compressed manner according to the line identification of the current charging line.
Step S112: and decompressing the pixel values of the plurality of sub-pixels associated with the compressed and stored line identification to obtain the pixel values of the plurality of sub-pixels associated with the decompressed line identification.
Step S113: and controlling each sub-pixel connected with the current charging circuit to be displayed as a corresponding pixel value according to the pixel values of the plurality of sub-pixels associated with the decompressed circuit identifier.
In step S108, when displaying, the display driver chip sequentially processes each charging line according to a certain sequence, so that the display driver chip obtains the line identifier of the current charging line when processing the charging line, and then performs step S109.
In step S109, the display driver chip may determine, according to the obtained line identifier of the current charging line, whether the current charging line is a first charging line or a second charging line, specifically, the charging line that is the first charging line in the dividing may be associated with a preset identifier, and then determine, in the executing of this step, whether the line identifier of the line is associated with the preset identifier to determine whether the current charging line is the first charging line; also can design into different sign and then distinguish first charging line and second charging line, discern its sign and then judge it and belong to first charging line or second charging line when carrying out this step.
If the current charging line is the first charging line, then step S110 is executed to determine the associated target pixel value based on the line identifier of the current charging line, and further display all sub-pixels connected to the current charging line as the target pixel value; if the current charging line is the second charging line, it indicates that the current charging line belongs to the second charging line, and then steps S111 to S113 may be executed.
In steps S111 to S113, the display driver chip may search for pixel values of a plurality of sub-pixels associated with the compressed and stored line identifier according to the line identifier of the current charging line, then decompress the pixel values of the plurality of sub-pixels associated with the compressed and stored line identifier to obtain pixel values of a plurality of sub-pixels associated with the decompressed line identifier, that is, pixel values of each sub-pixel connected to the current charging line, and further display each sub-pixel connected to the current charging line as a corresponding pixel value based on the pixel values of the plurality of sub-pixels associated with the decompressed line identifier.
In the embodiment designed above, the display driver chip determines whether the current charging line is the first charging line or the second charging line according to the line identifier of the current charging line, and when the current charging line is the first charging line, the display driver chip obtains the target pixel value corresponding to the current charging line based on the stored line identifier having the association relationship and the corresponding target pixel value, and further displays all sub-pixels connected to the current charging line as the target pixel value associated with the line identifier of the current charging line, so that when the charging line belonging to the first charging line is displayed, only the target pixel value corresponding to the line identifier thereof needs to be obtained, and further all sub-pixels connected thereto are displayed as the target pixel value, and it is not necessary to read the pixel value of each sub-pixel on the charging line stored in advance and then perform post-decompression processing as in the prior art, the designed data method can save the power consumption of reading and decompressing, and further reduce the power consumption of the display panel.
