Technical Field

Background

In order to simplify the touch operation of the user on the touch screen, the related art proposes an edge touch related technology.

Currently, edge touch mainly has two implementation modes: (1) enhancing the induction intensity of the edge touch signal in the existing display area; (2) and adding an edge touch sensor on the side surface of the terminal equipment.

The second method requires an additional sensor structure to be added to the terminal, which not only increases the manufacturing cost of the terminal, but also leads to a significant increase in the terminal volume.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a schematic cross-sectional view of a touch module according to an exemplary embodiment, where the touch module may be a device with a touch function, such as a mobile device like a mobile phone or a tablet computer, or a personal computer, and the following description mainly describes an exemplary embodiment of the invention with a terminal where the touch module is located as a mobile phone. As shown in fig. 1, the touch module includes: the touch screen 1 comprises a plurality of sensing areas 10, and the area of each sensing area 10 is equal to the minimum area of the touch screen capable of distinguishing touch signals.

In one embodiment, the minimum area of the touch screen capable of distinguishing the touch signal is related to the accuracy of the touch operation sensed by the touch screen, for example, the accuracy of the sensed touch operation is 1 mm, and then the minimum area may be 1 mm.

In one embodiment, the touch screen 1 may include a display panel 11 and a touch structure 12, and the touch module may further include a cover glass 13 covering the touch screen 1.

In one embodiment, the structure of the touch structure is not limited to the case shown in fig. 1. For example, the touch structure may be an In-Cell structure, that is, the touch structure is disposed on an array substrate of the display panel. The touch structure can also be an On-Cell structure, namely the touch structure is arranged between the color film substrate and the polarizer. The touch structure may also be an OGS structure, that is, the touch structure is formed on the cover glass.

In one embodiment, the display panel may be a liquid crystal display panel, and may also be an OLED (organic light emitting diode) display panel.

This touch module still includes:

and the edge structure 2 is arranged along the edge of the touch screen 1.

In one embodiment, as shown in fig. 1, the edge structure 2 may be a frame of a terminal where the touch module is located. In addition to the frame shown in fig. 1, the edge structure may be another structure disposed along the edge of the touch screen, such as a frame of a mobile phone case.

The first conductive structure 3 is disposed on a side of the edge structure 2 away from the touch screen 1 to form a touch area for a user to contact.

The second conductive structure 4 is electrically connected to the first conductive structure 3 and extends to a position corresponding to a preset area of the touch screen, wherein the preset area includes one or more sensing areas.

In an embodiment, the second conductive structure may cover the predetermined area, or may not cover the predetermined area, and only has a certain corresponding relationship with the predetermined area, for example, the second conductive structure may be disposed on a side of the edge structure close to the touch screen, perpendicular to the touch screen, and in contact with the predetermined area.

In one embodiment, the first conductive structure and the second conductive structure may be integral. Or there may be two separate parts of the electrical connection.

In one embodiment, the first conductive structure may be disposed on a side frame of the terminal as shown in fig. 1. And a plurality of first conductive structures may be disposed on one side frame of the terminal. Further, the first conductive structure may also be disposed on a multi-sided frame of the terminal.

Fig. 2 is a schematic diagram illustrating a touch module recognizing an edge touch operation in the related art. Fig. 3 is a diagram illustrating a touch module recognizing an edge touch operation according to an exemplary embodiment.

As shown in fig. 2, in the related art, when a user performs an edge touch operation, a finger generally touches an edge of the cover glass or a frame of the terminal, wherein the finger and the touch structure correspond to two poles of a coupling capacitor C1, respectively.

As shown in fig. 3, in one embodiment, when the user performs an edge touch operation on the terminal shown in fig. 1, a finger may contact the first conductive structure, wherein the second conductive structure and the touch structure respectively correspond to two poles of the coupling capacitor C2.

As can be seen from comparing fig. 2 and fig. 3, the second conductive structure in fig. 3 is closer to the touch structure than the finger in fig. 2, so that the coupling capacitor C2 in the embodiment of fig. 3 is larger than the coupling capacitor C1 in fig. 2, thereby substantially increasing the strength of the edge touch signal, and the touch module accurately determines the edge touch signal, so as to facilitate the terminal where the touch module is located to make an accurate response according to the edge touch signal.

According to the embodiments shown in fig. 1 and 3, the first conductive structure and the second conductive structure may be sheets of conductive materials, and only need to be respectively attached to the frame and the cover glass of the terminal, which has little influence on the volume of the terminal.

As shown in fig. 4A, when a user touches an edge of a pair, the user generally touches a region of the touch screen close to the frame, where 1-1 to 6-4 are sensing regions of the touch screen with the smallest area capable of resolving the touch signal. Since the area of the user's finger is larger than that of the sensing area, when touching the touch screen, multiple sensing areas are touched simultaneously, for example, the sensing areas 3-4, 4-4 and 5-4 shown in fig. 4A are touched, coupling capacitances are formed with the sensing areas 3-4, 4-4 and 5-4, and since the shape of the finger does not completely correspond to each sensing area, not only charge variation occurs in the sensing areas 3-4, 4-4 and 5-4, but also charge variation occurs in adjacent areas, for example, the generated charge variation is shown in fig. 4B.

Determining the signal of the edge touch based on the charge change shown in fig. 4B requires comprehensive consideration of the charge change amount of each sensing area where the charge change occurs, on one hand, the calculation is complex, and on the other hand, the determined signal of the edge touch has a small difference from the signal form generated when the user performs touch in other areas of the touch screen, which easily results in determining the edge touch as a non-edge touch.

As shown in fig. 5A, based on the embodiment shown in fig. 1, taking the frame as the edge structure and the second conductive structure covering the 3-4 sensing area (i.e. the predetermined area is the 3-4 sensing area) as an example, when a user performs edge touch, the user can touch the first conductive structure 3, since the first conductive structure 3 is electrically connected to the second conductive structure 4, the second conductive structure 4 will form a coupling capacitance with the 3-4 sensing area in the touch screen, and since the second conductive structure 4 is completely disposed corresponding to the 3-4 sensing area, only the 3-4 sensing area will be caused to generate charge variation, and the sensing area around the 3-4 sensing area will not be caused to generate charge variation, for example, as shown in fig. 5B.

Therefore, when the user performs edge touch based on the present embodiment, the touch signal (i.e., the charge variation) sensed by the touch screen corresponds to the preset area, and when the user performs non-edge touch within the touch screen, the touch signal sensed by the touch screen does not correspond to the preset area, so that the edge touch and the non-edge touch can be accurately distinguished based on the preset area, and further, the corresponding edge touch operation is accurately triggered according to the edge touch signal.

In one embodiment, the second conductive structure may cover a predetermined area of the touch screen, so that when a user touches the first conductive structure, the second conductive structure and the touch structure in the touch screen form a larger coupling capacitance, thereby generating a stronger touch signal to sensitively trigger the edge touch operation.

Optionally, the first conductive structure 3 includes a plurality of first sub-conductive structures 31, the second conductive structure 4 includes a plurality of second sub-conductive structures 41, each first sub-conductive structure 31 is electrically connected to one or more second sub-conductive structures 41, and each second sub-conductive structure 41 covers a different sub-region in the preset region;

the touch chip is further configured to trigger an edge touch operation according to the touch signal of the sub-area covered by each second sub-conductive structure 41.

In one embodiment, as shown in fig. 6, the first sub-conductive structure 31 is electrically connected to one second sub-conductive structure 41, wherein one second sub-conductive structure covers the 3-4 sensing area, and the other second sub-conductive structure covers the 5-4 conductive structure, and when a user touches the first sub-conductive structure corresponding to the second sub-conductive structure on the 3-4 sensing area, a first touch signal can be generated according to the charge change of the 3-4 sensing area; when a user contacts the first sub-conductive structure corresponding to the second sub-conductive structure on the 5-4 sensing area, a second touch signal can be generated according to the charge change of the 5-4 sensing area; and when the user simultaneously contacts the first sub-conductive structures corresponding to the second sub-conductive structures on the 3-4 sensing area and the 5-4 sensing area, a third touch signal can be generated according to the charge changes of the 3-4 sensing area and the 5-4 sensing area. According to the first touch signal, the second touch signal and the third touch signal, different edge touch operations can be triggered respectively.

In one embodiment, as shown in fig. 7, the first sub-conductive structure 31 may be electrically connected to two second sub-conductive structures 41, wherein one of the second sub-conductive structures covers the 3-4 sensing region, and the other second sub-conductive structure covers the 5-4 conductive structure, and when the first sub-conductive structure 31 is used, a fourth touch signal may be generated according to the charge changes of the 3-4 sensing region and the 5-4 sensing region. And further triggering corresponding edge touch operation according to the fourth touch signal.

In one embodiment, the embodiment shown in fig. 6 and the embodiment shown in fig. 7 may be combined, that is, both the first sub-conductive structures and the second sub-conductive structures are included in a one-to-one correspondence, and one first sub-conductive structure is included in a correspondence with a plurality of second sub-conductive structures.

Based on the embodiments shown in fig. 6 and 7, the user may trigger different edge touch operations by contacting different first sub-conductive structures.

Fig. 8 is a schematic structural diagram of another touch module according to an exemplary embodiment. As shown in fig. 8, the width of the first sub-conductive structure 31 is greater than the width of the second sub-conductive structure 41.

In one embodiment, since the second sub-conductive structure covers a preset area of the touch screen, and the preset area includes one or more sensing areas, but the area of the sensing area is often smaller, if the first sub-conductive structure and the second sub-conductive structure are set to be the same in width, it is inconvenient for a user to click on the first sub-conductive structure to be clicked. Therefore, for example, as shown in fig. 8, the width of the first sub-conductive structure may be set to be larger than the width of the second sub-conductive structure, so that the user can click on the desired clicked first sub-conductive structure.

In an embodiment, as shown in fig. 9, based on the embodiment shown in fig. 6, the widths of the two sub-conductive structures 41 may be set to be different, and the areas of the sensing regions covered by the two second sub-conductive structures with different widths are also different, for example, the sensing regions 3-4 are only covered by 50% of the area, and the sensing regions 5-4 are covered by 100% of the area, so that the intensities of the side touch signals generated by the two sensing regions are also different. Therefore, when a user touches different first sub-conductive structures, touch signals are generated in different sensing areas, different touch signals are generated in different sensing areas, and the first sub-conductive structure clicked by the user can be determined more accurately based on the two factors, so that corresponding touch operation is triggered. And more diversified touch signals can be generated, so that more types of touch operation can be triggered.

In one embodiment, as shown in fig. 10, the widths of the two second sub conductive structures 41 may be set to be different on the basis of the embodiment shown in fig. 7. This embodiment has similar effects to the embodiment shown in fig. 9, and will not be described herein again.

Optionally, at least two of the second sub-conductive structures 41 in the plurality of second sub-conductive structures 41 have different lengths.

Fig. 11 is a schematic structural diagram of another touch module according to an exemplary embodiment. As shown in fig. 11, on the basis of the embodiment shown in fig. 6, the lengths of the two second sub-conductive structures 41 may be set to be different, and the areas of the sensing regions covered by the two sub-conductive structures with different widths may also be different, for example, one second sub-conductive structure is longer and covers 3-2 and 3-4 sensing regions, and the other second sub-sensing region is shorter and covers 5-4 sensing regions. Therefore, when a user contacts different first sub-conductive structures, more diversified touch signals can be generated, and more types of touch operation can be triggered.

Fig. 12 is a schematic structural diagram of another touch module according to an exemplary embodiment. As shown in fig. 12, on the basis of the embodiment shown in fig. 7, the lengths of the two second sub conductive structures 41 may be set to be different. This embodiment has similar effects to the embodiment shown in fig. 11, and will not be described herein again.

It should be noted that the embodiments shown in fig. 9 and 11 may be combined, and the embodiments shown in fig. 10 and 12 may be combined, that is, the plurality of second sub-conductive structures may have different lengths and different widths.

In addition, the embodiments shown in fig. 6 to 12 only show the case of two second sub-conductive structures, the number of the second sub-conductive structures can be actually adjusted according to the requirement, and one first sub-conductive structure is not limited to be electrically connected to two second sub-conductive structures, and can also be electrically connected to more second sub-conductive structures.

the second conductive structure is arranged on one side, far away from the display panel, of the protective glass and/or arranged in the protective glass. And under the condition that the touch structure does not adopt an OGS structure, the second conductive structure can be arranged between the protective glass and the display panel.

In one embodiment, such as shown in fig. 1, the second conductive structure 4 may be disposed on a side of the protective glass 13 away from 11.

In one embodiment, as shown in fig. 13, the second conductive structure 4 may be disposed in the cover glass 13, so that the influence on the smoothness of the upper surface of the cover glass may be avoided.

And a plurality of first conductive structures may be disposed on a side frame of the package. Further, the first conductive structure can be arranged on a multi-side frame of the external member.

Similar to the embodiment shown in fig. 3, when the user performs an edge touch operation on the touch module shown in fig. 1, a finger may contact the first conductive structure, wherein the second conductive structure and the touch structure correspond to two poles of the coupling capacitor C2, respectively. Because the second conductive structure is close to the touch structure, a larger coupling capacitance can be formed, so that the strength of the edge touch signal is substantially improved, the edge touch signal is accurately determined by the touch module, and the terminal where the touch module is located can make an accurate response according to the edge touch signal.

Fig. 19 is a schematic cross-sectional view of another touch module according to an exemplary embodiment. The kit 6 comprises:

the cover body 63 is connected to the frame 62 of the kit and used for covering the touch screen 1;

a connection portion 7 for electrically connecting the first conductive structure 3 to the second conductive structure 4;

wherein the second conductive structure 4 is arranged between the frame 2 of the terminal and the frame 62 of the sleeve, and the connecting portion 7 is arranged in the frame 62 of the sleeve and/or arranged at an end face of the frame 62 of the sleeve.

In one embodiment, as shown in fig. 21, the first conductive structure 3 and the second conductive structure 4 may be electrically connected by a connection 7 in a rim 62 of the package. Although the second conductive structure is not parallel to the touch structure, the second conductive structure is still closer to the touch structure relative to the frame of the terminal, so that when a user touches the first conductive structure to perform edge touch, edge touch is performed relative to the frame of the contact terminal, and a stronger touch signal can be generated.
