Abstract
The utility model provides a touch screen and a touch type liquid crystal display panel. Multiple lines of a line zone of a touch screen visible region are parallel mutually, and the lines are folding lines; each two nonadjacent sides of the folding lines are non-intersected. As the lines are changed from multiple mutually parallel straight lines into multiple folding lines, the interference fringes generated by the lines are not laminated regularly and are very messy. Thus, obvious color fringes cannot be seen through human eye observation, so that a user can observe the displayed image more clearly.

Embodiment
Just as stated in the Background Art, the demonstration image of touch sensitive liquid crystal display panel can produce color fringe, makes the user can not clearly observe the demonstration image.The inventor discovers, the reason that produces this phenomenon mainly is, as shown in Figure 1, the partial schematic diagram that interferes for cabling in the prior art, many straight cabling 101 is parallel to each other, and cabling 101 is generally the ITO cabling, does not have any material between the cabling, the transmitance of ITO is certainly less than the transmitance in the space between the cabling, and grating has been formed in the space between many cablings and they self jointly like this.When this grating of light process, interfere phenomenon, be that light can strengthened in some zone, weaken in some zone, formed light and dark interference fringe 102, when the light through cabling was white light, white light can resolve into the light of multiple different colours, being presented on the interference fringe 102, is color fringe with regard to the bright fringe that shows as interference fringe 102.
The direction of interference fringe is all parallel with cabling 101, very rule distributes, can be clearly after the mutual superposition, especially in the intensive place of cabling, more interference fringe is superimposed, this phenomenon can be more obvious, and color fringe is easier of the human eye perception, when causing eye-observation touch sensitive liquid crystal display panel, can see very significantly color fringe, and then cause not seeing the image that to observe.
Based on this, the utility model provides a kind of touch-screen and touch display panel, and many cablings in the cabling district of described touch-screen viewing area are parallel to each other, and the shape of described cabling is broken line, and the non-conterminous both sides of described broken line are all non-intersect.
Touch-screen provided by the utility model and touch sensitive liquid crystal display panel, the cabling in the cabling district of touch-screen viewing area is changed to many broken lines by many straight lines that are parallel to each other, because cabling is broken line, so be equivalent to produce the grating of interference along different directions, then the interference fringe of Chan Shenging is also along different directions, other zone such as cabling corner also can produce interference in addition, the interference fringe direction that each zone produces is also inconsistent, the stack of interfering does not have rule, very mixed and disorderly, therefore during eye-observation induction less than tangible color fringe, thereby can make the user more clearly observe the demonstration image.
More than be core concept of the present utility model, can become apparent more for making above-mentioned purpose of the present utility model, feature and advantage, below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
A lot of details have been set forth in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here and implement, those skilled in the art can do similar popularization under the situation of the utility model intension, so the utility model is not subjected to the restriction of following public specific embodiment.
Secondly, the utility model is described in detail in conjunction with synoptic diagram, when the utility model embodiment is described in detail in detail; for ease of explanation; the sectional view of indication device structure can be disobeyed general ratio and be done local the amplification, and described synoptic diagram is example, and it should not limit the scope of the utility model protection at this.The three dimensions size that in actual fabrication, should comprise in addition, length, width and the degree of depth.
Present embodiment provides a kind of touch-screen, and as shown in Figure 2, many cablings 201 in the cabling district of described touch-screen viewing area are parallel to each other, and the shape of described cabling 201 is broken line, and the non-conterminous both sides of described broken line are all non-intersect.
In order to optimize the performance of touch-screen, the preferred comparison rule that the shape of cabling 201 is arranged, concrete, described cabling 201 comprises first rake 2011 that is parallel to each other and second rake 2012 that is parallel to each other, described first rake 2011 and second rake 2012 join end to end.
More preferably, make the equal in length of a plurality of first rakes 201 of described cabling 201, the equal in length of a plurality of second rakes 2012 of described cabling 201, described first rake 2011 can be set to unequal with the length of described second rake 2012, present embodiment more preferably makes the identical length of described first rake 2011 and second rake 2012 etc., and first rake 2011 that cabling 201 is adjacent and the angular range of second rake 2012 are 0 degree～180 degree.
Be example with two formed gratings of cabling below, the beneficial effect that the touch-screen that present embodiment is provided produces is described in detail, as shown in Figure 3, because cabling 201 is different with the transmitance in non-cabling zone, article two, the zone of cabling 201 and the space between the two and the two both sides has formed a grating jointly, from figure, cabling 201 comprises towards second rake 2012 of right side bending and first rake 2011 that bends towards the left side, the zone that defines second rake, 2012 places is the 3rd zone 301, and first rake 2011 that bends towards the left side is the 4th zone 302.
When the above-mentioned grating of light process, interfere, strengthen in some zone, weaken in some zone, form interference fringe, the interference fringe in the 3rd zone 301 is parallel to the cabling (i.e. second rake 2012) in the 3rd zone 301, and the interference fringe in the 4th zone 302 is parallel to the cabling (i.e. first rake 2011) in the 4th zone 302, as can be seen from Figure, two place's interference fringes are overlapped together.Because the interference fringe in the 3rd zone 301 and the interference fringe in the 4th zone 302 alternately occur, interference fringe can mixed and disorderly overlaping.
It below only is the simplest interference situation, owing to will take place as long as satisfy the condition interference of interfering, so the interference of Fa Shenging many than above-mentioned situation complexity in fact, do not have only the grating in the same area (as the 3rd zone 301) just can cause interference because be, cabling and the space between them in the zones of different (as the 301 and the 4th zone 302, the 3rd zone) also can form grating, and then interfere, in addition, the corner of cabling 201 equally also may interfere.Therefore, the interference situation that the cabling of broken line shape causes is very complicated, the interference fringe of different directions does not have rule, and mixed and disorderly is superimposed, and significantly interference fringe and color fringe have just disappeared, and, in the intensive zone of cabling 201, the stack situation of interference fringe is more complicated, and significantly interference fringe and color fringe just more can not occur, final when eye-observation touch sensitive liquid crystal display panel, also with regard to perception less than color fringe.
In the present embodiment, the obvious degree of the color fringe that human eye perceives is with adjacent first rake of cabling and the increase variation in wave shape of the angle between second rake, as shown in Figure 6, X represents the angle of cabling first rake and second rake, Y represents the obvious degree of color fringe, 90 degree are the cycle of a variation, and it is consistent that the obvious degree change situation of color fringe is spent with 90 degree～180 between 0 degree～90 degree.
Only between 90 degree～180 degree, be changed to the example explanation with angle, angle increases to the process of 135 degree from 90 degree, fading away of the color fringe that human eye perceives, when 135 spend, human eye can be observed color fringe hardly, and angle increases to the process of 180 degree from 135 degree, and it is obvious that color fringe becomes gradually, when 0 degree was spent with 180, the obvious degree of the color fringe in human eye institute perception road was identical.
Since the angle of first rake and second rake at 0 degree between 90 degree time, the degree of cabling bending is bigger, can cause the cabling area occupied bigger, so in actual fabrication, generally do not adopt the angle of the first adjacent rake of cabling and second rake in 0 scheme of spending (comprising endpoint value) between～90 degree.
According to top conclusion, in the touch-screen that present embodiment provides, first rake that described cabling is adjacent and the angle of second rake less than 180 degree, more preferably more than or equal to 120 degree, are less than or equal to 150 degree greater than 90 degree.
