Abstract
The invention provides a touch baseplate and a preparation method and a display device for the same, and belongs to the technical field of display. According to the invention, the problem that a connecting bridge in an existing touch baseplate can be broken easily and then influences touch effects of a touch display device can be solved. The touch baseplate provided by the invention is characterized in that a connecting bridge connected to a second sensing unit comprises at least one bending part as well as connecting positions located on two ends of the bending part, wherein the connecting bridge is not broken easily, and thus connection reliability can be enhanced. Meanwhile, when the touch baseplate is used in the display device, visibility of the connecting bridge can be reduced and effects of "shadow removal" are good because the connecting bridge is bent, and light refraction and reflection take place at the bending part. The touch baseplate provided by the invention is applicable to various display devices and is especially applicable to a flexible display device.

In the touch base plate of the present embodiment, the connecting bridge 3 of bending is difficult to disconnect, and it is permissible
Improve the reliability connected.Meanwhile, after using it in display device, due to connecting bridge 3
Being bending, light produces refraction, reflection at kink 31, so can reduce connecting bridge 3
Visuality, " disappear shadow " is effective.The touch base plate of the present invention is applicable to various display
Device, is particularly suited for flexible display apparatus.
Embodiment 2:
The present embodiment provides a kind of touch base plate, as shown in Fig. 3-11, including multiple first
Sensing unit 1 and multiple second sensing unit 2, described first sensing unit 1 and the second sense
Survey the same layer of unit 2, pass through between the most adjacent described first sensing unit 1
Be connected with the connecting portion 11 of layer, the most adjacent described second sensing unit 2 it
Between electrically connected by connecting bridge 3, described connecting bridge 3 overlapping with described connecting portion 11 and it
Between be provided with insulating barrier 4；Wherein,
Described connecting bridge 3 includes at least one kink 31, and kink two ends 31 are respectively
Electrically connect with two second adjacent sensing unit 2.
Wherein, the first sensing unit can be the sensing unit of logical induced signal, the second sense
Survey the touch control unit that unit can be logical touching signals；Or the first sensing unit is logical touching
The touch control unit of control signal, the second sensing unit is the sensing unit of logical induced signal, from
And realize touch-control, because of it it is known that do not repeat them here.
It is to say, the first sensing unit 1 is the most vertical with the second sensing unit 2 in Fig. 2
Directly, the two can be to synchronize to be formed, the i.e. first sensing unit 1 and the second sensing unit 2
Same layer.Wherein the connecting portion 11 and first of the first sensing unit 1 senses the same layer of unit 1,
And for the connecting bridge 3 that the second sensing unit 2 electrically connects is had kink 31, bending
Connecting bridge 3 be not easy disconnect, the reliability of connection can be improved.
The touch screen of the present invention is applicable to various display device, is particularly suited for Flexible Displays
Device, because Flexible Displays needs bending, it is easier to disconnected.It applies schematic diagram such as Figure 10
Shown in.
Meanwhile, after using it in display device, owing to connecting bridge 3 is bending, light
Produce refraction, reflection at kink 31, so can reduce the visuality of connecting bridge 3, " disappear
Shadow " effective.
Preferably, the bending angle of described kink 31 is more than 90 °.
It is to say, kink 31 obviously has certain angle (not being 0 °) between two
Straight line portion composition, this angle is bending angle.General 31 angle of bends of kink
Degree depends on the arrangement mode of pixel, and wherein, the bending angle of kink 31 is preferably obtuse angle,
Electrostatic will not be produced bad, point discharge can be avoided.
Preferably, described connecting bridge 3 also include respectively with two second adjacent sensings
