Specific implementation mode
To keep the embodiment of the present invention technical problems to be solved, technical solution and advantage clearer, below in conjunction with
Drawings and the specific embodiments are described in detail.
A kind of display device of the embodiment of the present invention offer and its working method can carry out the aobvious of a variety of resolution pictures
Show, and display device occur signal wire it is bad after, remain to be shown using display device.
The embodiment of the present invention provides a kind of working method of display device, and the display device includes N groups grid line and M group numbers
According to line, the N groups grid line and M group data lines limit multiple sub-pixes, and every group of grid line includes a plurality of grid line, every group of data line packet

For example the resolution ratio of display device is 4K, then display device includes 4096 grid lines and 2160 data lines, can be with
4096 grid lines are divided into N groups, 2160 data lines are divided into M groups, when display device is in high definition display pattern, 4096 grid
Line and 2160 data lines both participate in display；When display device is in low clear display pattern, corresponded to according to low clear display pattern
Resolution ratio determine the grid line group number and data line group number for participating in display, control corresponding grid line group number and data line group number and participate in
Display.In order to ensure to show the uniformity of picture, the grid line group number and data line group number for participating in display should be evenly distributed in display
On the display area of device, rather than concentrate on the part display area of display device.
Further, the display pattern of the display device includes normal displaying mode and malfunction coefficient pattern, it is described to
At least one set of grid line in the N groups grid line inputs gate drive signal, and at least one set of data into the M groups data line
Before the step of line input data signal, working method further includes：
It is bad or grid line is bad with the presence or absence of data line to detect the display device；
Bad or when grid line is bad there are data line, judge that the display device is in malfunction coefficient pattern.
Further, after judging that the display device is in malfunction coefficient pattern, the working method specifically includes：
When bad there are grid line in the n-th group grid line in detecting the N groups grid line, in addition to the n-th group
Other group of grid line inputs gate drive signal, and n is the positive integer no more than N；And/or
When bad there are data line in the m group data lines in detecting the M data line, to except the m groups it
Other group of outer data line input data signal, m are the positive integer no more than M.
If grid line occurs in display device during volume production in this way or data line is bad, it can utilize and remove undesirable grid
Other grid lines or data line except line or data line are shown, display device are lowered one's standard or status sale, without scrapping display dress
It sets, can effectively avoid wasting.During display device use, if display device grid line occurs or data line is bad,
User can change the resolution ratio of display device, using except undesirable grid line or data line by selecting different display patterns
Except other grid lines or data line shown, to extend the service life of display device.
