Fenestral fabric in mesh openings and the pixel unit 8 of display panel correspond to improve the reaction spirit of touch control electrode 5
Sensitivity, and then improve user experience.
Wherein, the side size range of the hexagon of metal grill is unlimited, and main and OLED luminescent layers 6 form pixel unit 8
Size variation and change；The shape of metal grill and pixel unit 8 can be consistent, and the shape of pixel unit 8 is hexagon；Metal
The shape of grid and pixel unit 8 can be inconsistent, and the shape of pixel unit 8 is not necessarily hexagon, can be circular, may be used also
Think other irregular figures, it is only necessary to metal routing be avoided to block pixel unit.
More specifically, as shown in Fig. 1 a, Fig. 1 b and Fig. 2, orthographic projection of the fenestral fabric on underlay substrate is located at each
In light tight region between pixel unit 8.
Aligned by the film layer of reticle mask version, it is ensured that upper and lower film layer fitting so that fenestral fabric in 8 institute of pixel unit
Projection in the plane is in the light tight region between each pixel unit 8, it is ensured that metal grill is nested in display panel
In gap between pixel unit 8 so that there is display panel good optics to disappear shadow effect.
There are following two modes in position of the touch control electrode layer 2 on touch base plate 1：
Mode one, as shown in figure 3, touch control electrode layer 2 is located at touch base plate 1 towards the one side of pixel unit 8.
The making of touch control electrode layer 2 is simple, it is easy to accomplish, and since touch control electrode layer 2 at this time is apart from formation pixel list
The OLED luminescent layers 6 of member 8 are relatively near, and the interference that the electric signal that touch control operation generates is subject to is larger, for the sensitivity of touch control operation
More preferably, touch-control performance is more excellent, it is necessary to repeatedly debugged to touch chip 3, to ensure precision that touch-control is shown.
Mode two, as shown in figure 4, touch control electrode layer 2 is located at the one side that touch base plate 1 deviates from pixel unit 8.
Touch control electrode layer 2 at this time apart from formed pixel unit 8 OLED luminescent layers 6 farther out, touch control operation generate electricity
The interference that signal is subject to is smaller so that the sensitivity of touch control operation is more preferable, and touch-control performance is more excellent.
