As shown in fig. 1, fig. 1 is a schematic flow chart of a data line numbering method provided in an embodiment of the present invention, and a specific flow of the data line numbering method may be as follows:
101. all data lines in the display are divided so that data lines belonging to the same COF are grouped.
Specifically, a display has a plurality of COF (Chip On Flex) substrates, and the clearer the display is, the more COF the display has, for example, a 4K display has 12 COFs, and an 8K display has 24 COFs. One COF has a plurality of data lines, for example, one COF in a 4K display and an 8K display has 960 data lines. In the embodiment, all data lines in the display are divided according to the COF, and the data lines belonging to the same COF are divided into one group, so that each group of data lines corresponds to one COF.
102. A unique one-digit serial number for each COF is determined.
Specifically, each COF is provided with a serial number, the serial number is a one-digit number, and the serial numbers of different COFs are different. The serial number of each COF can be used as the serial number of all data lines in the COF.
Preferably, each COF is given a unique one-digit serial number using a number or latin letters, i.e., a COF can be given a one-digit number or a latin letter.
It should be noted that, the COFs in the display are arranged in sequence, the serial number of each COF may be sequentially arranged from the first COF in the arrangement order of the COFs, and the arrangement order of the serial numbers may be a numerical order, a latin alphabetical order, or a combination order of the numerical order and the latin alphabetical order.
As a preferred embodiment, the setting of a unique one-digit serial number for each COF by using numbers or latin letters specifically includes:
based on the arrangement order of COFs in the display, the serial number of each COF is sequentially set in the latin alphabet order from latin alphabet a.
Specifically, the present embodiment employs one latin letter and sets the serial number of each COF in order from the first COF in the latin letter order. Preferably, the serial numbers are arranged in latin letter order starting from latin letter a. For example, the sequence number of a first COF is set to a, the sequence number of a second COF is set to B, the sequence number of a third COF is set to C, and so on.
As another preferred embodiment, the setting of a unique one-digit serial number for each COF by using numbers or latin letters specifically includes:
when the number of COFs in the display is less than 10, sequentially setting the serial number of each COF in numerical order from the number 1 based on the arrangement order of the COFs in the display.
Specifically, since the number of COFs in this embodiment is less than 10, the present embodiment preferentially adopts one digit and sets the serial numbers of the COFs in order from the first COF in numerical order. Preferably, the serial number is set in numerical order starting with the number 1. For example, the sequence number of a first COF is set to 1, the sequence number of a second COF is set to 2, the sequence number of a third COF is set to 3, and so on.
As another preferred embodiment, the setting of a unique one-digit serial number for each COF by using numbers or latin letters specifically includes:

Specifically, since the number of COFs in this embodiment is greater than or equal to 10, and one digit cannot satisfy the serial number setting of COFs of 9 or more, this embodiment sets the serial number of a COF by combining digits and latin letters, that is, the 1 st to 9 th COFs set the serial number by digits, and the COFs after the 9 th set the serial number by latin letters. Preferably, the sequence numbers of the 1 st to 9 th COFs are sequentially set to 1 to 9, and from the 10 th COF, the sequence numbers are sequentially set in latin alphabet order. For example, the sequence number of the first COF is set to 1, the sequence number of the second COF is set to 2, the sequence number of the 9 th COF is set to 9, the sequence number of the 10 th COF is set to a, the sequence number of the 11 th COF is set to B, and so on.
For example, COFs in 4K displays and 8K displays are preferably numbered in combination with latin letters. Wherein, the number of COFs in the 4K display is 12, according to the arrangement order of COFs in the 4K display, the sequence numbers of the first 9 COFs are corresponding to 1 to 9, and the sequence numbers of the last 3 COFs are corresponding to a to C, as shown in table 1.
COF ordering 1 2 3 4 5 6 7 8 9 10 11 12
Serial number 1 2 3 4 5 6 7 8 9 A B C
The number of COFs in the display of table 18K is 24, and according to the arrangement order of COFs in the display of 8K, the sequence numbers of COFs arranged in the first 9 are corresponding to 1 to 9, and the sequence numbers of COFs arranged in the last 15 are corresponding to a to O, as shown in table 2.
COF ordering 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
Serial number 1 2 3 4 5 6 7 8 9 A B C D E F G H I J K L M N O
TABLE 2
103. The unique sub-number of each data line in its belonging COF is determined.
Specifically, each data line in each COF is provided with a sub-number, and the sub-numbers of the data lines in the same COF are different, and the sub-numbers of the data lines in different COFs may be the same.
Preferably, the unique sub-number of each data line in its associated COF is set by a number, i.e. at least one digit can be used as the sub-number of a data line in its associated COF.
It should be noted that, the plurality of data lines in the COF are arranged in sequence, the serial number of each data line may be sequentially set from the first data line according to the arrangement order of the data lines, and the setting order of the serial numbers may be a numerical order.
As a preferred embodiment, the digitally setting a unique sub-number of each data line in its COF specifically includes:
in each COF, the sub-numbers of each data line in the COF are sequentially arranged in numerical order from the number 1 based on the arrangement order of the data lines in the COF.
Specifically, a sub-number is set to the data line in each COF, respectively. In setting the sub-numbers to the data lines in one COF, the serial number of each data line is set in order from the first data line in numerical order using at least one digit. Preferably, the sub-numbers are arranged in numerical order from the data line 1. For example, the sub-number of the first data line is set to 1, the sub-number of the second data line is set to 2, the sub-number of the third data line is set to 3, and so on.
For example, the number of data lines per COF in the 4K display and the 8K display is 960. The sub-numbers of 960 data lines in each COF are correspondingly set to 1 to 960 in turn in the data line arrangement order in each COF.
104. Merging the serial number and the sub-number of each data line into the number of the data line in the display; the serial number of the data line is the serial number of the COF to which the data line belongs.
Specifically, after the serial number of each COF and the sub-number of each data line in the COF to which the data line belongs are determined, each data line in the display corresponds to one serial number and one sub-number, and the serial number of one data line is spliced in front of the sub-number of the data line, so that the number of the data line in the display can be obtained.
As a preferred embodiment, the merging the serial number and the sub-number of each data line into the number of the data line in the display specifically includes:
acquiring the highest number digit in all the sub-numbers;
for the data line with the sub-number of the highest number digit, splicing the serial number and the sub-number of the data line into the number of the data line in the display;
and for the data line with the sub-number of bits lower than the highest number of bits, adding a blank bit before the sub-number of the data line so as to enable the number of the sub-number after the blank bit is added to be the highest number of bits, and splicing the serial number of the data line and the sub-number after the blank bit is added to be the number of the data line in the display.
It should be noted that, for convenience in viewing the subsequent data line numbers, the highest number bit number in the sub-numbers is obtained, and the bit complement operation is performed on the sub-numbers whose bit numbers do not reach the highest number bit number. Specifically, a blank bit is added before the sub-number whose bit number does not reach the highest number bit number, so that the bit number of the sub-number after the blank bit is added is the highest number bit number. Further, the serial number and the sub-number having the highest number digit of each data line are spliced into a data line number, i.e., the number of the data line in the display. After the data line number is obtained, the data line number can be designed in the display.
For example, when the number of COFs in the 4K display is 12 and the number of data lines in each COF is 960, the number of data lines in the 4K display is 1 × 1 to 1960, 2 × 1 to 2960, …, and C × 1 to C960 in this order. The number of COFs in the 8K display is 24, the number of data lines in each COF is 960, and the data lines in the 8K display are numbered 1 × 1-1960, 2 × 1-2960, …, C × 1-C960, … and O × 1-O960 in sequence. Wherein denotes an empty cell.
As can be seen from the above, the data line numbering method provided in this embodiment divides all data lines in a display according to the COFs to which the data lines belong, further determines the unique one-digit serial number of each COF, and determines the unique sub-number of each data line in the COF to which the data line belongs, so as to number the data lines according to the serial numbers and the sub-numbers, thereby shortening the length of the data line number, saving the space occupied by the data line number, avoiding the data line number from conflicting with surrounding designs, improving the space utilization, ensuring the convenience of testing, yield, and abnormal analysis, and ensuring the best conditions of design and yield.
In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, therefore, the scope of the present invention shall be determined by the appended claims.
