It is defined in a attached drawing, then in subsequent attached drawing does not need that it is further discussed.
In order to promote the homogeneity of display panel, inventor has carried out following grind to display panel in the prior art
Study carefully:
- Fig. 4 referring to Figure 1, Fig. 1 are a kind of planar structure schematic diagrams for display panel that the prior art provides, and Fig. 2 is figure
For 1 display panel provided in a kind of enlarged diagram of region W, Fig. 3 is a kind of signal waveform for the display panel that Fig. 1 is provided
Figure, Fig. 4 are another signal waveforms for the display panel that Fig. 1 is provided.As shown in Figs 1-4, display panel includes 00 He of substrate
Viewing area AA, viewing area AA include: grid line 01, touch control electrode 02, stitch 03, driving chip 04 and pixel electrode 05 at electrode quarter,
Grid line 01 includes grid line 1 and grid line 2 012, and pixel electrode 05 includes pixel electrode 1 and pixel electrode two
052, grid line 1 is electrically connected with pixel electrode 1, and grid line 2 012 is electrically connected with pixel electrode 2 052, touch-control electricity
Pole 02 is covered on the top of grid line 1, and electrode is equipped between two adjacent column touch control electrodes 02 and carves seam 03, electrode carves seam 03
It inside include a grid line 2 012, touch control electrode 02 is multiplexed with public electrode in the display stage.Due to touch control electrode 02 and grid
Exist between line 1 and overlap, therefore, there are coupled capacitor C1 between touch control electrode 02 and grid line 011；Again due in electrode
Carve the grid line 2 012 in seam 03 and between touch control electrode 02 without overlapping, therefore, electrode carves the grid line 2 012 in seam 03
Coupled capacitor C2 ratio C1 between touch control electrode 02 is small.In the case that coupled capacitor is different, touch control electrode 02 will cause
Voltage is inhomogenous, and since touch control electrode 02 is multiplexed with public electrode, is showing the display brightness of stage display panel not
It is uniform, in this case, driving chip 04 need to grid line 2 012 control pixel electrode 05 carry out luminance compensation, with
So that the brightness of display panel is uniform.
A kind of scanning mode that the prior art provides is: display panel needs just to sweep in display to be swept with counter.Assuming that grid
Line has M item, so-called just to sweep, and is exactly that gate driving circuit (not shown) is believed according to direction Y1 to the offer driving of grid line 01
Number, i.e., gate driving circuit is according to from the 1st article of grid line (grid line farthest apart from driving chip 04) to the M articles grid line
The sequence of (grid line nearest apart from driving chip 04) provides driving signal；It is so-called it is counter sweep, be exactly gate driving circuit according to
Driving signal is provided to grid line 01 with direction Y1 exactly opposite direction Y2, i.e., gate driving circuit is according to from the M articles grid
Sequence of the line (grid line farthest apart from driving chip 04) to the 1st article of grid line (grid line farthest apart from driving chip 04)
Driving signal is provided.
Continuing with referring to Fig. 1-3, below to display panel when just sweeping with counter sweep, driving chip 04 carries out luminance compensation meeting
The problem is illustrated.
Under normal conditions, according to the resolution ratio of display panel and the size of touch control electrode 02, electrode quarter can be calculated
The position of grid line 2 012 in seam 03.The position that electrode carves seam 03 is constant, and therefore, electrode carves the grid line 2 012 in seam 03
Position is fixed.As shown in Figure 3-4, Fig. 3-4 shows display panel when just sweeping with counter sweep, and coupled capacitor C and data are believed
The corresponding relationship of number DA is C1 by the coupled capacitor between the grid line 1 covered of touch control electrode 02 and touch control electrode 021,
The coupled capacitor that electrode carves grid line 2 012 and touch control electrode 021 in seam 03 is C2, C2 < C1；What grid line 1 controlled
The received data-signal DA of pixel electrode 051 is one DA1 of data-signal, and the pixel electrode 052 that grid line 2 012 controls is received
Data-signal DA is two DA2 of data-signal, DA2 < DA1.When display panel, which is in, just sweeps state, grid line 2 012 and touch-control
The coupled capacitor C2 of electrode 021 is less than the coupled capacitor C1 between grid line 1 and touch control electrode 021, therefore, in order to compensate for
Because of coupled capacitor bring luminance difference, needs to carry out luminance compensation to the pixel electrode 05 that grid line 2 012 controls, that is, need
Two DA2 of data-signal is transmitted to pixel electrode 052, pixel electrode 052 is the last line picture that touch control electrode 021 covers at this time
Plain electrode；And when display panel be in it is counter sweep state when, the coupled capacitor C2 of grid line 2 012 and touch control electrode 021 is less than grid
Coupled capacitor C1 between polar curve 1 and touch control electrode 021, therefore, there is still a need for the pixel controlled grid line 2 012
Electrode 05 carries out luminance compensation, that is, the data-signal DA transmitted to pixel electrode 052 is needed to remain as two DA2 of data-signal, but
It is that pixel electrode 052 is the first row pixel electrode that touch control electrode 021 covers at this time.That is, for the same touch-control electricity
For pole 02, the position of the pixel electrode for carrying out luminance compensation 05 is needed to be changed.Driving chip 04 is to display panel
When carrying out luminance compensation, for touch control electrode 021, since the position just swept with need to carry out luminance compensation when counter sweep is different
It causes, therefore driving chip 04 also needs to calculate the position of the pixel electrode 05 of compensation.Specifically, as shown in figure 1, figure 3 and figure 4, right
For touch control electrode 021, when just sweeping, needing the pixel column for carrying out luminance compensation is last line, still, in counter sweep,
Needing the pixel column for carrying out luminance compensation is the first row.And for driving chip 04, counter sweep is switched to from direction Y1 is just swept
Reversed Y2 as will just sweep pattern switching to counter and sweep mode, and the needs of driving chip 04, which recalculate, needs to carry out luminance compensation
The position of pixel electrode 05, if do not recalculated, luminance compensation will malfunction, this undoubtedly considerably increases driving chip 04
Design difficulty, to increase the design cost of driving chip 04.
