Embodiment 1

[0051] Such as figure 1 As shown, the sensing layer of the display module in this embodiment includes a sensing block layer 1 and a metal wiring layer 2 . Wherein, the metal wiring layer 2 is disposed on the surface of the sensing block layer 1 .

[0052] Such as figure 2 As shown, the sensing block layer 1 includes a plurality of sensing patterns 11, and the plurality of sensing patterns 11 are arranged in M ​​rows and N columns, where M and N are both positive integers.

[0053] Each sensing pattern 11 includes a plurality of sensing blocks ( figure 2 Not shown in ) and a plurality of driving blocks arranged along the second direction ( figure 2 not shown). Specifically, such as image 3 As shown, the sensing pattern 11 includes two sensing blocks 111 oppositely arranged along a first direction and two driving blocks 112 oppositely arranged along a second direction.

[0054] Wherein, the first direction is a horizontal direction, and the second direction is a vertic...

Embodiment 2

[0063] The sensing layer of the display module of this embodiment is a further improvement on Embodiment 1. The metal wiring layer 2 also includes a plurality of third connection lines, and the two sensing sub-blocks a in each sensing block 111 of the sensing pattern 11 are connected by a third connecting wire.

[0064] Specifically, when the value of m is 2, such as Figure 4 As shown, one end of the third connection line 23 is respectively connected to an induction sub-block a and a first connection line 21 , and the other end is connected to another induction sub-block a.

[0065] When the value of m is 3, such as Figure 5 As shown, one end of the third connecting wire 23 is connected to one inductive sub-block a, the middle part is connected to a first connecting wire 21 , and the other end is connected to another inductive sub-block a.

[0066] Additionally, if Figure 6 As shown, the sensing layer also includes an insulating layer 3 . The insulating layer 3 is dispo...

Embodiment 3

[0087] Such as Figure 16 As shown, the display module of this embodiment includes the display glass 4 and the sensing layer of the display module in the second embodiment.

[0088] The sensing block layer 1 in the sensing layer is attached on the display glass 4 .

[0089] in addition. In the specific implementation process of this embodiment, the display module may also include the display glass 4 and the sensing layer of the display module of the first embodiment.

[0090] The sensing layer in the display module of this embodiment reduces the number of outgoing lines on both sides of the sensing layer and reduces the space on both sides of the display module of the touch screen without reducing the touch experience and touch accuracy, thereby realizing A larger screen-to-body ratio achieves the purpose of reducing the width of the frame and meets the development needs of a full-screen display.

Abstract

The invention discloses an induction layer of a display module, the display module and a touch screen. The induction layer comprises an induction block layer and a metal wiring layer. The induction block layer comprises a plurality of induction patterns, and each induction pattern comprises a plurality of induction blocks and a plurality of driving blocks; each induction block comprises two induction sub-blocks, and an interval in the induction block in each column of induction patterns forms a wiring groove in the first direction; the metal wiring layer comprises a plurality of first connecting wires and a plurality of second connecting wires; a first connecting wire is arranged in each wiring groove; and the driving blocks in the n rows of induction patterns are connected through the same second connecting line. On the basis that the touch experience and the touch precision are not reduced, the number of outgoing lines on the two sides of the induction layer is reduced, the space onthe two sides of the display module of the touch screen is reduced, and therefore the larger screen-to-body ratio is achieved, the purpose of reducing the frame width is achieved, and the developmentrequirement of a full screen is met.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a sensing layer of a display module, a display module and a touch screen. Background technique [0002] With the rapid development of electronic technologies (such as smart watches, smart phones, tablet computers, notebook computers, all-in-one computers, robots, etc.), people have higher and higher requirements for the screen ratio of the screen of smart devices. However, in existing smart devices, due to the large number of metal wires on both side frames of the display module of the touch screen, it takes up a large space, thereby limiting the development of the full screen technology of the screen. Contents of the invention [0003] The technical problem to be solved by the present invention is that the number of metal wires on both sides of the display module of the touch screen in the prior art is relatively large, which takes up a large space, thereby limiting the develop...
