In fact, for above-mentioned touch panel shown in Fig. 2, the making of figure transfer printing process can be used, according to process requirements with
And the laying angle and length of accuracy Design electrode section.
Based on any of the above-described scheme, in this application, it is contemplated that orthographic projection of the touch-control structure on substrate, with OLED element
Orthographic projection of the light emitting sub-pixel of layer on substrate is not overlapped, and therefore, the touch-control wiring in touch-control structure can be arranged in OLED
The gap location of the light emitting sub-pixel of element layer, certainly exists：The line width of touch-control wiring is less than between two neighboring light emitting sub-pixel
Gap.
Although between touch-control structure is arranged on adjacent light emitting sub-pixel, and avoiding the position of light emitting sub-pixel, and
Blocking for the light that touch-control structure sends out light emitting sub-pixel cannot be completely eliminated.This is because with reference to Figure 15 (a) and Figure 15
(b) shown in, the thin-film encapsulation layer 402 on light emitting sub-pixel 401 has certain thickness, and touch-control structure 403 is located at film
On encapsulated layer 402, and then, when being watched in touch panel front, touch-control structure 403 will not hide light emitting sub-pixel 401
Gear；But when being watched with different visual angles, if touch-control structure is oversized, still light can be blocked, from
And display brightness is reduced, it influences to watch quality.Wherein, visual angle is the emitting brightness of light emitting sub-pixel to be caused to drop due to blocking
Viewing angle during to 50%.In other words, this is the limit that brightness reduces, and touch-control structure can at most block single luminous sub- picture
The light-emitting area of element 50%.
For this purpose, present applicant proposes a solution, i.e., the line width that is connected up by rationally designing the touch-control of touch-control structure,
To avoid when being watched with visual angle, light emitting sub-pixel is blocked in touch-control wiring；It is corresponding for any adjacent light emitting sub-pixel
At gap, two outermost sides of touch-control structure at a distance of slit centers distance no more than predetermined threshold value；Wherein, it is described to shine
1/2 length value of sub-pixel and the gap distance values and value, subtract the predetermined threshold value and obtain difference, the difference and institute
State tangent value of the ratio of the thickness value of thin-film encapsulation layer for the visual angle of touch-control display panel.
It should be noted that touch-control structure therein can be understood as following several situations：
Situation 1：Crossed electrode item, correspondingly, the touch-control structure at gap are only the wiring of the first touch-control or the second touch-control cloth
Line, with reference to shown in Figure 16 (a).
Situation 2：Distorted grid electrode, the touch-control structure at gap include the wiring of the first touch-control and the wiring of the second touch-control, ginseng
According to Figure 16 (b) Suo Shi, the first touch-control, which is routed in orthographic projection on substrate and is routed in orthographic projection on substrate with the second touch-control, to partly overlap
Or it is not overlapped.
Specifically, it is the section of two light emitting sub-pixel positions of arbitrary neighborhood of touch panel with reference to shown in Figure 17
Schematic diagram, wherein, light emitting sub-pixel A and light emitting sub-pixel B are located in substrate 501 (upper surface in such as figure), light emitting sub-pixel A with
Luminescent layer 502 where light emitting sub-pixel B is covered by thin-film encapsulation layer 503, and touch-control structure 504 is arranged on 503 table of thin-film encapsulation layer
Face, in fact, it is a touch-control wiring S to be shown in FIG. 8.In fact, may be that two touch-controls connect up at the gap, dislocation is set
It puts or is set positioned at different film layers, referring in particular to the above situation 1- situations 3.
With reference to shown in Figure 17, two outermost sides of touch-control structure 504 (being only a touch-control wiring at this time) are at a distance of gap
The distance at center is no more than predetermined threshold value；It is interpreted as the peak width that touch-control structure 504 occupies and is not more than twice of default threshold
Value.Wherein, 1/2 length value of the light emitting sub-pixel and the gap distance values and value, subtract the predetermined threshold value and obtain
The ratio of difference, the difference and the thickness value of the thin-film encapsulation layer is the tangent value at the visual angle of touch-control display panel.
Moreover, based on shown in Figure 17, the width value that the thicknesses of layers value of touch-control wiring is connected up with touch-control in touch-control structure is in
It is negatively correlated.After the predetermined threshold value determines, you can determine that in the distance at a distance of slit centers (shown in dotted line) be predetermined threshold value pair
The region answered sets setting touch-control in range and connects up.
Referring now still to shown in Figure 17, wherein, according to triangle law it is found that the thickness of the tangent value at visual angle and thin-film encapsulation layer
Degree, one half value of spacing of adjacent light emitting sub-pixel, one half value of width of single light emitting sub-pixel and half of line width values.
Specifically, the line width that touch-control connects up in touch-control structure meets the following formula：
L≤2*l- α=2* [K/2- (N*tan θ-M)]-α (1)
Wherein, the L is the line width of touch-control wiring, and the l is 1/2 line width of touch-control wiring, and the α is missed for process capability
Difference, the K are the corresponding gap spacing of adjacent light emitting sub-pixel, and the M is 1/2 length of light emitting sub-pixel, and the N is film
The thickness of encapsulated layer, the θ are the visual angle of touch-control display panel.
And in practical manufacturing process, process capability error alpha=Δ Align+ Δ CDRange, wherein, Δ Align is
Equipment aligning accuracy；Δ CDRange is line width technique float value.The corresponding gap spacing K of the adjacent light emitting sub-pixel is 20 μ
m；1/2 length M of the light emitting sub-pixel is 10 μm；The thickness N of the thin-film encapsulation layer is 8 μm；The equipment aligning accuracy
Δ Align is ± 0.5 μm；The line width technique float value Δ CDRange is ± 0.5 μm.
The line width that touch-control wiring is calculated according to above-mentioned assignment is less than or equal to 5.36 ± 1.0 μm, in fact, if according to routine
RGB three primary colors light emitting sub-pixel arrangement modes, when 260PPI resolutions design, the line width of touch-control wiring should be controlled at 4.36 μm
Hereinafter, belong to process safety range.It should be noted that the line width of touch-control wiring is only to set one in gap in Fig. 8
The situation of touch-control wiring, and be only theoretical calculation, certain deviation may be present in actual process.
Above-mentioned that principle explanation is carried out only in case of in Figure 17, the touch-control structure in the case of other can also
It designs, is not blocked when being watched with viewing visual angle based on 50% light emitting sub-pixel area in a similar way.
In fact, in this application, it is contemplated that the presence of thin-film encapsulation layer, then, when being watched with visual angle, sight is inevitable
It is reflected in thin-film encapsulation layer, therefore, it is necessary to pay close attention to influence of the refractive index of thin-film encapsulation layer to sight.
With reference to shown in Figure 18, in touch-control structure is not considered in the case of touch-control wiring thickness, it is assumed that sight is as light
It propagates, enters thin-film package film layer from the transparent protective layer in touch-control wiring, light refraction occurs in interface, injects again later
On light emitting sub-pixel, conversely, when light emitting sub-pixel shines, it also can be according to similar propagated.Specifically, in touch-control structure
The line width of touch-control wiring meets the following formula：
Wherein, the L is the line width of touch-control wiring, and the l is 1/2 line width of touch-control wiring, and the α is missed for process capability
Difference, the K are the corresponding gap spacing of adjacent light emitting sub-pixel, and the M is 1/2 length of light emitting sub-pixel, and the N is film
The thickness of encapsulated layer, visual angles of the θ for touch-control display panel, the θ1To enter the folding after thin-film encapsulation layer with the visual angle
Firing angle, the n are the refractive index of the thin-film encapsulation layer.
So as to through the above technical solutions, being laid at the gap of adjacent light emitting sub-pixel in touch-control structure, avoid front
Light emitting sub-pixel is blocked in touch-control wiring when light is seen；Moreover, the application is additionally contemplates that existing block is asked when being watched with visual angle
Topic avoids excessively blocking to light emitting sub-pixel by rationally designing the line width of touch-control wiring, at least ensures light emitting sub-pixel
