Each bar touching signals line 431 ~ 434 is connected with touch control electrode 421 ~ 424 electricity, and each touch control electrode 421 ~ 424 is electrically connected with at least one touching signals line 431 ~ 434.Such as, schematically show each touching signals line 431 ~ 434 in Fig. 4 and be electrically connected with a touch control electrode 421 ~ 424, and each touch control electrode 421 ~ 424 is electrically connected with a touching signals line 431 ~ 434.Particularly, touch control electrode 421 is electrically connected with touching signals line 431 by connecting line 451, touch control electrode 422 is electrically connected with touching signals line 432 by connecting line 452, touch control electrode 423 is electrically connected with touching signals line 433 by connecting line 453, and touch control electrode 424 is electrically connected with touching signals line 434 by connecting line 454.Many touching signals line 431 ~ 434, connecting line 451 are arranged with layer with multiple touch control electrode 421 ~ 424.
The integrated touch-control display panel of the present embodiment, by touching signals line 431 ~ 434 and touch control electrode 421 ~ 424 are arranged with layer, touching signals line and touch control electrode can be reduced at least in part when being positioned at different retes, the stray capacitance formed between touching signals line and touch control electrode, thus the display characteristic and the touch control characteristics that promote display panel.
In addition, because touching signals line 431 ~ 434, connecting line 451 are arranged with layer with touch control electrode 421 ~ 424, in the manufacturing process of the integrated touch-control display panel of the application, touching signals line 431 ~ 434, connecting line 451 can make with touch control electrode 421 ~ 424 simultaneously and be formed in same manufacture craft, compared with existing integrated touch-control display panel, decrease processing step, reduce process complexity.
It should be noted that, in order to make improvement of the present invention be embodied highlightedly, in the de-scription, omitting the description to some known structures in integrated touch-control display panel.Those skilled in the art are on the basis obtaining technical scheme disclosed in the present embodiment, can expect that other known structure (such as, array base palte, color membrane substrates and the liquid crystal layer that is formed between array base palte and color membrane substrates) of the present embodiment and existing integrated touch-control display panel combines and do not need to pay performing creative labour.
Continue with reference to Fig. 4, the integrated touch-control display panel of the present embodiment, except structure as above, also comprises multiple display pixel 440, a plurality of data lines D1 ~ D4 and many gate lines G 1 ~ G4.
Wherein, multiple display pixel 440 is arranged in array, and such as, Fig. 4 schematically shows the multiple display pixels 440 with 4 × 4 array arrangements.Data line D1 ~ D4 is used for multiple display pixel transmitting display signal therefor.Gate lines G 1 ~ G4 is used for providing scanning drive signal to multiple display pixel 440.
In some optional embodiments, the many touching signals lines 431 ~ 434 of the present embodiment and multiple touch control electrode 421 ~ 424 can be used as public electrode in the display stage, thus provide common signal to multiple display pixel 440.
In some optional embodiments, each touching signals line 431 ~ 434 can between adjacent two display pixels 440.By touching signals line 431 ~ 434 being formed at the interval region between adjacent two display pixels 440, touching signals line 431 ~ 434 can be avoided at least in part on the impact of the penetrance of integrated touch-control display panel panel and brightness etc., thus promote display effect further.
Here, it should be noted that, " between " implication narrowly can not be interpreted as that the orthogonal projection of each touching signals line on substrate and the orthogonal projection of two adjacent with it display pixels on substrate are without overlapping, and be appreciated that there is intension widely.Such as, in application scenes, the orthogonal projection of touching signals line on substrate and the orthogonal projection of two adjacent with it display pixels on substrate partly overlapping, another part is then in the interval region between adjacent two display pixels.So, the interval region between adjacent display pixel can correspondingly arrange less, thus is conducive to the realization of high PPI (PixelperInch).
The integrated touch-control display panel of the present embodiment, except structure as above, also comprises multiple pixel electrode.
In some optional implementations, pixel electrode can between substrate 410 and touch control electrode 421 ~ 424.In other words, in these optional implementations, when making the integrated touch-control display panel of the present embodiment, pixel electrode can complete prior to touch control electrode, to make in the integrated touch-control display panel that finally completes, pixel electrode is in than the position of each touch control electrode closer to substrate 410.In these optional embodiments, in a display pixel, touch control electrode can have at least one first slit, and touch control electrode is formed at least one first electrode by the first slits.
As shown in Figure 5, that schematically shows a touch control electrode 510, and multiple display pixels 541 ~ 544 corresponding with it.In display pixel 541, touch control electrode 510 comprises two the first slits 511,512.Along the bearing of trend of the first slit 511,512, touch control electrode has been split to form three first electrodes 521,522,523.
It should be noted that, here, " segmentation " one the implication of word narrowly should not be interpreted as and make each first electrode mutually " insulation ", and can be understood as, than " insulation ", there is intension widely.Such as, in application scenes, although the touch control electrode in a display pixel is defined multiple first electrode by multiple first slit " segmentation ", be still electrically connected to each other between each first electrode.And in other application scenarioss, touch control electrode in a display pixel can be formed first electrode of multiple mutually insulated by multiple first slit " segmentation ", these first electrode such as can be electrically connected by touching signals line corresponding with this touch control electrode respectively, thus each first electrode realizing belonging to a touch control electrode has equal current potential.
In addition, although in Fig. 5, each first slit in two the first slits 511 and 512 and display pixel 542 ~ 544 is of similar shape and bearing of trend, and this is only schematic.In actual applications, can according to application scenarios need the shape of the first slit, quantity and bearing of trend are set, the scheme of the application is not restricted this.
In other optional embodiments, touch control electrode can between substrate and pixel electrode.In other words, in these optional implementations, when making the integrated touch-control display panel of the present embodiment, touch control electrode can complete prior to pixel electrode, to make in the integrated touch-control display panel that finally completes, touch control electrode is in than the position of each pixel electrode closer to substrate.In these optional embodiments, pixel electrode can have at least one second slit.In a display pixel, pixel electrode can be shaped at least one second electrode by the second slits.In these optional embodiments, such as also can be had structure as shown in Figure 5 and shape by the pixel electrode after the second slits.But this shape of pixel electrode and structure are also schematic.It will be appreciated by those skilled in the art that, in a display pixel, the shape of the second slit, quantity and bearing of trend can be arranged according to practical application equally, and the scheme of the application is not restricted this.
Continue with reference to Fig. 4.In some optional embodiments, the bearing of trend of touching signals line 431 ~ 434 can be identical with the bearing of trend of data line D1 ~ D4.In application scenes, such as, data line D1 ~ D4 can be considered as straight-line segment.In these application scenarioss, touching signals line 431 ~ 434 is identical with data line D1 ~ D4 bearing of trend such as be can be understood as each bar touching signals line 431 ~ 434 and is parallel to each other with pieces of data line D1 ~ D4.In other application scenarioss, due to the shape of display pixel and/or the demand of array arrangement mode, data line can be considered as broken line.In these application scenarioss, touching signals line 431 ~ 434 is identical with data line D1 ~ D4 bearing of trend such as be can be understood as, touching signals line 431 ~ 434 is also broken line, and each broken line piecewise-parallel of each broken line of touching signals line 431 ~ 434 and data line D1 ~ D4.Or although touching signals line 431 ~ 434 is not parallel with data line D1 ~ D4 or piecewise-parallel, the overall bearing of trend of the two is identical.
In these optional embodiments, many touching signals lines 431 ~ 434 have the first orthogonal projection in substrate place plane.Data line D1 ~ D4 has the second orthogonal projection in substrate place plane.Each first orthogonal projection and second orthogonal projection overlapping at least partly.
Here, the first orthogonal projection, the second orthogonal projection can be understood as touching signals line and data line along the direction perpendicular to substrate 410 to the projection of substrate 410.
Because each touching signals line 431 ~ 434 is between adjacent two display pixels, and under normal circumstances, data line D1 ~ D4 is also between adjacent two display pixels.By arranging the cabling of each touching signals line 431 ~ 434 and each data line D1 ~ D4, with make each first orthogonal projection and second orthogonal projection overlapping at least partly, the spacing between two adjacent display pixels can be made less, thus more display pixel of can arranging in unit area, be beneficial to the realization of high PPI, and then promote display effect.
In some optional embodiments, touching signals line and data line can have structure as shown in Figure 6 and relative position relation.Specifically, as shown in Figure 6, between adjacent two display pixels 611 and 612, touching signals line 620 can have the 3rd slit 621 (being also the openwork part in Fig. 6 in touching signals line 620), and the 3rd slit 621 has the 3rd orthogonal projection in substrate place plane.3rd orthogonal projection and the second orthogonal projection have overlapping at least partly.In other words, the orthogonal projection of data line 630 on substrate and the 3rd orthogonal projection of slit 621 on substrate overlapping at least in part.
Further, in these optional embodiments, on the direction vertical with the bearing of trend of data line, the 3rd orthogonal projection can cover the second orthogonal projection.In other words, on the direction perpendicular to data line 630 bearing of trend, the width of the 3rd slit 621 is greater than the width of data line 630, makes in its width direction, and the orthogonal projection of data line 630 can fall into the orthogonal projection of the 3rd slit 621 just.
So, by offering the 3rd slit 621 in the position corresponding with data line 630 of touching signals line 620, the stray capacitance formed between the rete at the rete at data line 630 place and touching signals line 630 place can be made to reduce further.
In some optional embodiments, between adjacent two display pixels, touching signals line can be become two the 3rd electrodes by the 3rd slits, and two the 3rd electrodes are used separately as the public electrode into its immediate display pixel.
Continue with reference to Fig. 6, touching signals line 620 be divide into left and right two parts (i.e. two the 3rd electrodes) by the 3rd slit 621, the part in left side can be used as the public electrode of display pixel 621, and provides common signal to display pixel 621 during showing.Similarly, the part on right side can be used as the public electrode of display pixel 622, and provides common signal to display pixel 622 during showing.
Shown in Figure 7, be the schematic diagram of the integrated touch-control display panel of another embodiment of the application.
Similar with the embodiment shown in Fig. 4, the integrated touch-control display panel of the present embodiment comprises substrate (not shown), be arranged on multiple touch control electrode on substrate and many touching signals lines.Wherein, multiple touch control electrode is arranged in array, and multiple touch control electrode mutual insulating.Each bar touching signals line is connected with a touch control electrode electricity, and each touch control electrode is electrically connected with at least one touching signals line.In Fig. 7, be a block touch control electrode 710 in each dotted line frame.Each touch control electrode 710 also can be multiplexed with public electrode in the display stage, and provides common signal to each display pixel 720.
In the present embodiment, further defining multiple touch control electrode is block type electrode, and each block type electrode is the array arrangement of M capable and N row.Wherein M, N are positive integer, and column direction is identical with the bearing of trend of data line.
In the present embodiment, arrange the touch control electrode of (1≤n≤N) for any m capable (1≤m≤M) n-th, be divided at least m sub-electrode by least m-1 bar touching signals line, wherein m, n are positive integer.
Fig. 7 A shows in the integrated touch-control display panel of the present embodiment, the schematic layout relation of touch control electrode and touching signals line.In Fig. 7 A, in order to the layout relationship of outstanding touch control electrode and touching signals line, have ignored the description of the shape to each touch control electrode and touching signals line itself.
Each dotted line frame in Fig. 7 A represents a block touch control electrode, and schematically shows the array arrangement that touch control electrode is 3 row 3 row in Fig. 7 A.For the touch control electrode 710 (i.e. m=3, n=1) that the 3rd row the 1st in Fig. 7 arranges, this touch control electrode 710 is defined three (m) sub-electrode, i.e. sub-electrode 711, sub-electrode 712 and sub-electrodes 713 by two (m-1 bar) touching signals line 721 and 722 segmentations.
Wherein, touching signals line 721 is the touching signals line that the touch control electrode arranged with the 2nd row the 1st is connected, and touching signals line 722 is the touching signals line that the touch control electrode arranged with the 3rd row the 1st is connected.
Similarly, again for the touch control electrode 730 (i.e. m=3, n=2) that the 3rd row the 2nd in Fig. 7 A arranges, this touch control electrode 730 is defined three sub-electrodes, i.e. sub-electrode 731, sub-electrode 732 and sub-electrode 733 by touching signals line 741 and touching signals line 742 segmentation.Wherein, touching signals line 741 is the touching signals line that the touch control electrode arranged with the 2nd row the 2nd is connected, and touching signals line 742 is the touching signals line that the touch control electrode arranged with the 3rd row the 2nd is connected.
Those skilled in the art can understand, the quantity of the sub-electrode that touch control electrode is formed by the segmentation of touching signals line, relevant with the quantity of touching signals line.Such as, when each touch control electrode is electrically connected with two touching signals lines, the touch control electrode of capable n-th row of m will be divided into 2m sub-electrode.By that analogy, when each touch control electrode is electrically connected with k bar touching signals line, the touch control electrode of capable n-th row of m will be divided into k × m sub-electrode.Those skilled in the art obtain embodiment as shown in Figure 7 integrated touch-control display panel technical scheme basis on, the quantity of the touching signals line of touch control electrode electrical connection can be arranged at according to embody rule scene, and each touch control electrode be divided into the sub-electrode of respective numbers.
In addition, when each touching signals line for penetration type design and identical with the quantity of the touching signals line that each touch control electrode connects time, each touch control electrode is by the sub-electrode of cut formation equal number.Such as, if each touch control electrode is connected with a touching signals line, in the touch control electrode array of M × N array arrangement, each touch control electrode will be cut and form M sub-electrode.Similarly, if each touch control electrode is connected with k bar touching signals line, when adopting the touching signals line of penetration type design, in the touch control electrode array of M × N array arrangement, each touch control electrode will be cut and form k × M sub-electrode.
For Fig. 7 B, each touching signals line designs for penetration type, and in other words, each bar touching signals line length is equal, and all extends to the relevant position of the capable touch control electrode of M from the relevant position of the first row touch control electrode.
So, in Fig. 7 B, the touch control electrode 750 that the 1st row the 1st arranges is split by touching signals line 761 and touching signals line 762, forms three (M) sub-electrode 751, sub-electrode 752 and sub-electrodes 753.Similarly, the touch control electrode 770 that the 3rd row the 1st arranges is split by touching signals line 763 and touching signals line 761, forms three (M) sub-electrode, i.e. sub-electrode 771, sub-electrode 772 and sub-electrodes 773.。
In the present embodiment, as shown in figures 7 a and 7b, because each touching signals line and touch control electrode are arranged with layer, cannot conductor layer electrical connection at touch control electrode place between m the sub-electrode belonging to a touch control electrode together.
