Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display module. Background Art

[0002] With the continuous development of display technology, touch technology has been widely used in various electronic products in daily work and life. Since users can directly touch the display module with their hands or other objects to input information, it can reduce or even eliminate the user's dependence on other input devices (such as keyboards, mice, remote controls, etc.), making it easier for users to operate. Touch technologies include electromagnetic touch, capacitive touch and resistive film touch, among which electromagnetic touch technology uses the coil in a specific electromagnetic pen to make the electromagnetic induction coil on the display module produce a magnetic field change, thereby generating a weak current, and the touch detection part calculates the touch point position.

[0090] See also Figures 10 to 12 The first sub-driving coil 2311 further includes a third sub-driving unit 23113 , which is connected to the first sub-driving unit 23111 .

[0091] In some embodiments, see Figures 10 to 12 The driving coil 231 and the first touch signal line 221 are arranged to cross each other. In the area where the driving coil 231 and the first touch signal line 221 cross each other, both the driving coil 231 and the first touch signal line 221 are single-layer structures. In the area where the driving coil 231 and the first touch signal line 221 cross each other, the driving coil 231 is only provided with the third sub-driving unit 23113. The third sub-driving unit 23113 is arranged to overlap with the first touch signal line 221 in this area. In this way, the driving coil 231 and the first touch signal line 221 are short-circuited to avoid the occurrence of touch failure, thereby improving the process yield of the display module.

[0092] In some embodiments, see Fig.12 The touch layer 2 further includes a third floating electrode 2013, and the third floating electrode 2013 is arranged in the same layer as the second sub-driving coil 2312, that is, the second conductive layer 202 includes the third floating electrode 2013.

Along the film thickness direction of the touch layer, the third floating electrode 2013 is overlapped with the first sub-driving coil 2311.

[0093] By adding a third floating electrode 2013 between the second sub-driving coil 2312 and the first touch signal line 221, on the one hand, it is possible to prevent the second sub-driving coil 2312 and the first touch signal line 221 from being short-circuited and causing touch failure; on the other hand, the overlapping area of ​​the driving coil 231 and the first touch signal line 221 can be reduced, thereby reducing the parasitic capacitance between the driving coil 231 and the first touch signal line 221, thereby improving the sensitivity and accuracy of capacitive touch and electromagnetic touch.

[0094] In some embodiments, see Fig.12The touch layer 2 includes a plurality of third floating electrodes 2013, which are arranged between the second sub-driving coil 2312 and the first touch signal line 221 at intervals along the first direction X, and a row of third floating electrodes 2013 is disposed between the second sub-driving coil 2312 and the first touch signal line 221.

Along the film thickness direction of the touch layer, the fifth floating electrode 2015 is disposed overlappingly with the third sub-driving portion 23113 of the first sub-driving coil 2311.

[0098] By setting the overlapping portion of the first touch signal line 221 and the first sub-driving coil 2311 as a floating electrode, the overlapping area of ​​the driving coil 231 and the first touch signal line 221 can be further reduced, so as to further reduce the parasitic capacitance between the driving coil 231 and the first touch signal line 221, thereby further improving the sensitivity and accuracy of capacitive touch and electromagnetic touch.

[0109] In some embodiments, see Fig.16 The touch layer 2 further includes a tenth floating electrode 2020, which is disposed in the same layer as the first touch electrode 211, that is, the second conductive layer 202 includes the tenth floating electrode 2020.

[0110] By setting part of the electrodes in the first touch electrode 211 as floating electrodes, the overlapping area of ​​the first touch electrode 211 and the cathode layer in the display panel can be reduced, thereby reducing the parasitic capacitance between the first touch electrode 211 and the cathode layer, thereby improving the display effect while improving the sensitivity and accuracy of capacitive touch.
