Embodiment
Below will with the plural embodiment of graphic exposure the present invention, as clearly stated, the details in many practices will be explained in the following description.But the technician being familiar with this area should recognize, in some embodiments of the present invention, the details in these practices is also non-essential, does not therefore apply to limit the present invention.In addition, for the purpose of simplicity of illustration, some known usual structures and assembly illustrate it by the mode simply illustrated in the drawings.In addition, for the ease of reader's viewing, in graphic, the size of each assembly not illustrates according to actual ratio.
Fig. 1 illustrates the top view of the contact panel according to an embodiment of the present invention.As shown in Figure 1, contact panel can comprise cover plate 100, transparent electrode layer 200 and signal lead 300.Cover plate 100 has shading region 110 (region in figure outside thick frame line) and photic zone 120 (region in figure in thick frame line).Shading region 110 can have light screening material in wherein, watches assembly below shading region 110 to prevent user.Photic zone 120 does not have light screening material in wherein, with the display frame allowing user can watch the display panel below photic zone 120, and as the visible area of contact panel.Shading region 110 is be positioned at outside photic zone 120, and can around photic zone 120.Transparent electrode layer 200 is be covered on the photic zone 120 of cover plate 100.Signal lead 300 is be covered on the photic zone 120 of cover plate 100 completely, and signal lead 300 is electrically connected transparent electrode layer 200.
In the above-described embodiment, the visibility of signal lead 300 is lower than the visibility of the shading region 110 of cover plate 100, so that signal lead 300 is more sightless compared to the shading region 110 of cover plate 100.Therefore, signal lead 300 need not be blocked material and covered, and can be covered in completely and do not have on the photic zone 120 of light screening material in cover plate 100, thus the scope of shading region 110 can be reduced, be beneficial to the design of narrow frame, and also can expand the scope of photic zone 120, in order to the visible area scope expanding contact panel.
Should be appreciated that, described in this specification, it " visibility " is represent object relative to human eye, the difficulty that can be aware.For example, namely the visibility height of an assembly represents this assembly and is easily perceived by human eye, and on the contrary, low this assembly that namely represents of the visibility of an assembly is difficult to be perceived by human eye.Therefore, the visibility of signal lead 300 is lower than the visibility of the shading region 110 of cover plate 100, human eye being made when watching contact panel, more not easily perceiving signal lead 300, and visually can ignore the existence of signal lead 300.
For example, in some embodiments, the material of signal lead 300 can be transparent conductive material, such as: tin indium oxide (indiumtinoxide), indium zinc oxide (indiumzincoxide) or zinc oxide aluminum (aluminumzincOxide) etc., but the present invention is not as limit.Material due to signal lead 300 is transparent, therefore its visibility is lower than the visibility of the shading region 110 of cover plate 100.In other words, human eye is easier to discover lighttight shading region 110, and more not easily discovers transparent signal lead 300, therefore brain visually can ignore the existence of signal lead 300.
In some embodiments, the width of signal lead 300 can be micron order.For example, signal lead 300 be less than or equal to 5 microns.The signal lead 300 with above-mentioned size is superfine micro-and inconspicuous relative to human eye, and brain can be made visually to ignore the existence of signal lead 300.Because the signal lead 300 with above-mentioned size is superfine micro-and inconspicuous relative to human eye, therefore in some embodiments, when signal lead 300 has above-mentioned size, the material of signal lead 300 also can be opaque conductive material, such as: the metal such as gold, silver or copper, but the present invention is not as limit.
In some embodiments, when signal lead 300 is all positioned at photic zone 120 with transparent electrode layer 200, transparent electrode layer 200 can be distributed in the middle section of photic zone 120, and signal lead 300 can be distributed in the neighboring area of photic zone 120.Because transparent electrode layer 200 and signal lead 300 are be distributed in the zones of different in photic zone 120, therefore can prevent signal lead 300 from contacting the Different electrodes block of transparent electrode layer 200, and the situation be short-circuited.But because transparent electrode layer 200 is only distributed in the middle section of photic zone 120, and distribution-free is in the neighboring area of photic zone 120, therefore the middle section cording of photic zone 120 is only had to have touch controllable function.
Therefore, in some embodiments, as shown in Figure 1, each signal lead 300 is change with transparent electrode layer 200 phase.In other words, each signal lead 300 can be positioned at directly over transparent electrode layer 200 or immediately below, but not peripheral around transparent electrode layer 200.That is transparent electrode layer 200 can be covered with whole photic zone 120, and to be positioned at directly over signal lead 300 or immediately below, so can expand the scope of transparent electrode layer 200 further, thus expand contact panel can touch area.In addition, can consult Fig. 2, this figure illustrates the sectional view of contact panel along A-A ' line of Fig. 1.As shown in Figure 2, contact panel can comprise insulation course 400.Insulation course 400 can be distributed on transparent electrode layer 200 to whole property, and can clip between transparent electrode layer 200 and signal lead 300, in case stop signal lead-in wire 300 contacts and short circuit with the Different electrodes block in transparent electrode layer 200.The material of insulation course 400 can be light transmissive material, can watch the display frame of the display panel below photic zone 120 in order to user.
Insulation course 400 has plural lead-in wire through hole 410.Transparent electrode layer 200 and signal lead 300 are be electrically connected through lead-in wire through hole 410.For example, lead-in wire through hole 410 can expose the subregion of transparent electrode layer 200, and the end of signal lead 300 can be arranged in lead-in wire through hole 410, and contact with the partially transparent electrode layer 200 being exposed to lead-in wire through hole 410, thus realize the effect that signal lead 300 is electrically connected with transparent electrode layer 200.Thus, when transparent electrode layer 200 produces capacitance variations because of the touching of user, touching signals corresponding to this capacitance variations can pass to outer treatment circuit (not being shown in this figure) by signal lead 300, thus obtains the information such as position of touch.
In some embodiments, as shown in Figure 2, transparent electrode layer 200, insulation course 400 can be stacked on cover plate 100 from lower to upper with signal lead 300.In other words, transparent electrode layer 200 is than insulation course 400 closer to cover plate 100, and insulation course 400 is than the signal lead 300 be positioned at outside lead-in wire through hole 410, closer to cover plate 100.In some embodiments, as shown in Figure 2, signal lead 300 only can fill out the lead-in wire through hole 410 being distributed in local.In some embodiments, signal lead 300 also can fill up whole lead-in wire through hole 410.
In some embodiments, as shown in Figure 1, transparent electrode layer 200 can comprise plural first electrode block 210, plural second electrode block 220 and complex connecting line 230.First electrode block 210 is arrange along first direction Y.Each connecting line 230 connects adjacent two first electrode blocks 210, that is, wantonly two adjacent the first electrode blocks 210 are all connected by a connecting line 230, therefore can be electrically connected by many connecting lines 230 along multiple first electrode blocks 210 that first direction Y arranges.Second electrode block 220 is arrange along second direction X.Second direction X is crossing with first direction Y.For example, second direction X and first direction Y is perpendicular.In other words, the orientation of the second electrode block 220 and the orientation of the first electrode block 210 are perpendicular.For example, as shown in Figure 1, the second electrode block 220 is laterally arrange, and the first electrode block 210 is longitudinally arrange.Second electrode block 220 is separate with the first electrode block 210 and connecting line 230 phase, to prevent electric connection first electrode block 210.Second electrode block 220 is apart from one another.In order to be electrically connected the second electrode block 220 that these phases are separated, contact panel also comprises bridging line 500, with the second electrode block 220 that bridge joint is adjacent.
Furthermore, can consult Fig. 3, this figure illustrates the sectional view of contact panel along B-B ' line of Fig. 1.As shown in Figure 3, insulation course 400 has relative upper surface 401 and lower surface 402.Lower surface 402 contacts transparent electrode layer 200, and upper surface 401 is transparent electrode layer 200 dorsad.Bridging line 500 is the upper surface 401 being arranged at insulation course 400.Insulation course 400 has two bridge joint through holes 420.Bridging line 500 is be electrically connected adjacent two second electrode blocks 220 through two bridge joint through holes 420 of insulation course 400.Specifically, the bridge joint through hole 420 of Fig. 3 shownschematically left can expose the subregion of the second electrode block 220 of left, and the bridge joint through hole 420 of Fig. 3 shownschematically right can expose the subregion of the second electrode block 220 of right.The two ends, left and right of bridging line 500 can lay respectively at the bridge joint through hole 420 of left with the bridge joint through hole 420 of right, and contact the second electrode block 220 of left and the second electrode block 220 of right respectively.Thus, bridging line 500 can be electrically connected adjacent two second electrode blocks 220 separated mutually.As shown in Figure 1, wantonly two adjacent the second electrode blocks 220 are all connected by a bridging line 500, therefore can be electrically connected by many bridging lines 500 along multiple second electrode blocks 220 of second direction X arrangement.
Another because bridge joint through hole 420 only exposes the second electrode block 220, and do not expose connecting line 230 as shown in Figure 3, therefore, connecting line 230 and bridging line 500 be separate by insulation course 400, and be positioned at the relative both sides of insulation course 400.Thus, insulation course 400 can prevent connecting line 230 from contacting with bridging line 500, and causes short circuit.
In some embodiments, as shown in Figure 3, transparent electrode layer 200, insulation course 400 can be stacked on cover plate 100 from lower to upper with bridging line 500.In other words, transparent electrode layer 200 is than insulation course 400 closer to cover plate 100, and insulation course 400 is than the bridging line 500 be positioned at outside bridge joint through hole 420, closer to cover plate 100.
In some embodiments, as shown in Figure 1, contact panel can comprise plural outer lead 800 and lead-in wire pooling zone 600.These outer leads 800 connect many barss lead-in wire 300 respectively.Outer lead 800 is come together in lead-in wire pooling zone 600, in order to electric connection process circuit (not being illustrated in figure).For example, pooling zone 600 can be provided with flexible circuit board (FPC) with lead-in wire, make all signal leads 300 can be electrically connected electronic package on flexible circuit board, and the touching signals that transparent electrode layer 200 senses is passed to the electronic package on flexible circuit board.In some embodiments, outer lead 800 and signal lead 300 can be integrated.For example, outer lead 800 and signal lead 300 can be the different sections of same wire.
In some embodiments, as shown in Figure 1, lead-in wire pooling zone 600 is be covered on the shading region 110 of cover plate 100.In other words, lead-in wire pooling zone 600 is be blocked district 110 covered, and can not be revealed in outside contact panel.Thus, even if lead-in wire pooling zone 600 is provided with flexible circuit board or other treatment circuits, covering because lead-in wire pooling zone 600 can be blocked district 110, user also can not see this flexible circuit board or other treatment circuits.
In some embodiments, cover plate 100 can be a printing opacity plate body, its material can be glass, polycarbonate (polycarbonate, PC), poly terephthalic acid second two fat (polyethyleneterephthalate, PET), polymethyl methacrylate (polymethylmesacrylate, PMMA), polysulfones (polysulfone, or other cyclenes copolymers (cyclicolefincopolymer) etc., but the present invention is not as limit PES).Shading region 110 can arrange light shield layer to realize by above-mentioned printing opacity plate body partly, and is photic zone 120 without the remaining area arranging light shield layer.For example, can on the regional area of printing opacity plate body painting black photoresistance, make this regional area become shading region 110.
Fig. 4 illustrates the top view of the contact panel according to another embodiment of the present invention.As shown in Figure 4, the Main Differences between present embodiment and Fig. 1 illustrated embodiment is: the contact panel of present embodiment can comprise ground wire 700.Ground wire 700 is around signal lead 300.In other words, ground wire 700 is the periphery being positioned at signal lead 300, to provide the effect of electrostatic screening.In some embodiments, ground wire 700 does not change with transparent electrode layer 200 phase.In other words, ground wire 700 can not to be positioned at directly over transparent electrode layer 200 or immediately below, the static discharge (electrostaticdischarge, ESD) produced to prevent ground wire 700 affects transparent electrode layer 200, and then affects the function of touch-control sensing.For example, because transparent electrode layer 200 is be covered on the photic zone 120 of cover plate 100, therefore ground wire 700 can be covered on the shading region 110 of cover plate 100, and due to shading region 110 and photic zone 120 be two regions separated, therefore can make ground wire 700 not with transparent electrode layer 200 phase repeatedly.In addition, because ground wire 700 is be covered on shading region 110, and district 110 can be blocked cover, therefore the material of ground wire 700 can be opaque conductive material, and its width can be limited in less than 5 microns, and comparative signal lead-in wire 300 is wider.
Fig. 5 illustrates the top view of the contact panel according to another embodiment of the present invention.As shown in Figure 5, Main Differences between present embodiment and Fig. 4 illustrated embodiment is: the transparent electrode layer 200 of present embodiment has fluting 212 and 222, fluting 212 is be opened in the first electrode block 210, fluting 222 is be opened in the second electrode block 220, fluting 212,222 partly changes mutually with at least one of signal lead 300, that is fluting 212 and 222 is just to signal lead 300, thus reduce signal disturbing.Specifically, when signal lead 300 changes mutually with transparent electrode layer 200, signal lead 300 and transparent electrode layer 200 can produce a small amount of coupling capacitance, thus disturb touching signals.Through observing, coupling capacitance system is proportional to signal lead 300 and amasss with the right opposite of transparent electrode layer 200, therefore, when the first electrode block 210 offers fluting 212, because the first electrode block 210 can reduce with the right opposite of signal lead 300 is long-pending, therefore both coupling capacitances can be reduced, thus reduce the signal disturbing to the first electrode block 210.Similarly, when the second electrode block 220 offers fluting 222, because the second electrode block 220 can reduce with the right opposite of signal lead 300 is long-pending, therefore both coupling capacitances can be reduced, thus reduce signal lead 300 to the signal disturbing of the second electrode block 220.
Specifically, can consult Fig. 6, this figure illustrates the sectional view of contact panel along C-C ' line of Fig. 5.As shown in Figure 6, the first electrode block 210 is be positioned at immediately below signal lead 300, and both be separate by insulation course 400.In order to be beneficial to the slimming design of contact panel, the thickness of insulation course 400 is generally micron order (as 1.25 microns), when the thickness of insulation course 400 is micron order, first electrode block 210 and signal lead 300 are only separated by micron-sized spacing, and easily produce a small amount of coupling capacitance, but because the first electrode block 210 has plural number fluting 212, therefore it is long-pending with the right opposite of signal lead 300 to reduce the first electrode block 210, and can reduce coupling capacitance.Should be appreciated that, although this figure only explains with the first electrode block 210, the structure of the second electrode block 220 and its fluting 222 and effect thereof are also similar in appearance to above explanation, therefore not repeated description.
212 and 222 the area of the first electrode block 210 and the second electrode block 220 can be made to decline owing to slotting, therefore the resistance of the first electrode block 210 and the second electrode block 220 can be caused to rise, therefore, fabricator can weigh the resistance sizes of the first electrode block 210 and the second electrode block 220, with the signal disturbing degree of the first electrode block 210 and the second electrode block 220, determine quantity and the size of fluting 212 and 222.
Fig. 7 illustrates the top view of the contact panel according to another embodiment of the present invention.As shown in Figure 7, the Main Differences between present embodiment and Fig. 4 illustrated embodiment is: the change of the stacking order of transparent electrode layer 200a, insulation course 400a, signal lead 300a and bridging line 500a.Furthermore, can consult Fig. 8, this figure illustrates the sectional view of contact panel along D-D ' line of Fig. 7.As shown in Figure 8, signal lead 300a, insulation course 400a and transparent electrode layer 200a system are stacked on cover plate 100 from lower to upper.Specifically, signal lead 300a system is covered on cover plate 100, and the insulation course 400a of part is covered on signal lead 300a, and the lead-in wire through hole 410a system of insulation course 400a exposes the subregion of signal lead 300a.The transparent electrode layer 200a system of part is covered on insulation course 400a, and the transparent electrode layer 200a system of part is arranged in lead-in wire through hole 410a, and activation signal lead-in wire 300a, to be electrically connected signal lead 300a.
Fig. 9 illustrates the sectional view of contact panel along E-E ' line of Fig. 7.As shown in Figure 9, bridging line 500a, insulation course 400a and transparent electrode layer 200a system are stacked on cover plate 100 from lower to upper.Furthermore, bridging line 500a system is covered on cover plate 100, and the insulation course 400a system of part is covered on bridging line 500a, and separates bridging line 500a and connecting line 230a.The two bridge joint through hole 420a systems of insulation course 400a expose the two ends, left and right of bridging line 500a respectively.The transparent electrode layer 200a system of part is covered on insulation course 400a, and the second electrode block 220a system that the two-phase of transparent electrode layer 200a is separated is positioned partially in two bridge joint through hole 420a respectively, and the two ends, left and right of contact bridge wiring 500a, to be electrically connected by bridging line 500a.
As shown in Figure 7, in some embodiments, transparent electrode layer 200a has plural number fluting 212a and 222a, fluting 212a system is opened in the first electrode block 210a, fluting 222a system is opened in the second electrode block 220a, fluting 212a, 214a partly change mutually with at least one of signal lead 300a, thus reduce signal disturbing.For example, can consult Figure 10, this figure illustrates the sectional view of contact panel along F-F ' line of Fig. 7.As shown in Figure 10, the first electrode block 210a system of transparent electrode layer 200a is positioned at directly over signal lead 300, and both be separate by insulation course 400a.Because the first electrode block 210a has plural number fluting 212a, therefore the right opposite that can reduce the first electrode block 210a and signal lead 300a amasss, thus reduces coupling capacitance.Should be appreciated that, although this figure only explains with the first electrode block 210a, the structure of the second electrode block 220a and its fluting 222a and effect thereof are also similar in appearance to above explanation, therefore not repeated description.
11 to 14 figure illustrates the manufacturing flow chart of the display panel of Fig. 7.First, as shown in figure 11, signal lead 300a, bridging line 500a, ground wire 700a and outer lead 800a can be formed.Furthermore, signal lead 300a and bridging line 500a can be formed on the photic zone 120 of cover plate 100, and ground wire 700a and outer lead 800a is formed on the shading region 110 of cover plate 100, and make ground wire 700a around signal lead 300a, and make outer lead 800a connection signal lead-in wire 300a.In some embodiments, when the material of signal lead 300a and outer lead 800a is lighttight metal, and time identical with the material of bridging line 500a and ground wire 700a, signal lead 300a, bridging line 500a, ground wire 700a and outer lead 800a can be formed on cover plate 100 in processing procedure.
Then, as shown in figure 12, insulation course 400a can be formed on cover plate 100, and cover signal lead 300a, bridging line 500a, ground wire 700a (can Figure 11 be consulted) and outer lead 800a.Then, lead-in wire through hole 410a can be formed on insulation course 400a, and expose the signal lead 300a of part, make signal lead 300a can be electrically connected the follow-up transparent electrode layer 200a (can Fig. 7 be consulted) produced through lead-in wire through hole 410a.Then, bridge joint through hole 420a can be formed on insulation course 400a.Two bridge joint through hole 420a can expose the two ends, left and right of bridging line 500a respectively, make bridging line 500a can be electrically connected the adjacent biseptate second electrode block 220a (can consult Fig. 7) of the follow-up transparent electrode layer 200a produced through two bridge joint through hole 420a.
