Description
Technical Field
[0001] This application relates to the technical field of electronic devices, and particularly to an electronic device and a display module. Background Art
[0002] With the continuous innovation of electronic devices, borderless touchscreens are widely favored by consumers. In particular, mutual capacitance touchscreens determine the touch position by measuring the capacitance change between the transmitting electrode and the receiving electrode. Such screens have various characteristics such as high precision, anti-interference ability, and stable multi-touch performance, making mutual capacitance one of the preferred technologies for touchscreens in modern smart phones, tablet computers, and other devices. Because the cancellation of the touchscreen border changes the original electrode leads laid out around the screen to internal traces within the screen, but this lead will cause crosstalk to adjacent electrodes, thus affecting the touch accuracy. The above problems need to be solved urgently. Utility Model Content

[0043] This specification may use the phrase "in one embodiment", "in another embodiment", "in yet another embodiment" or "in other embodiments", which may each refer to one or more of the same or different embodiments according to the present application.
[0044] Mutual capacitance touch screen is an advanced capacitive touch screen technology that can achieve multi-touch, and has high precision, fast response speed and good anti-interference ability, and is widely used in consumer electronic products, including smart phones, tablet computers, navigation systems and various industrial and medical devices. Its principle is to determine the touch position by measuring the capacitance change between the transmitting electrode and the receiving electrode.
[0045] The mutual capacitance touch screen mainly consists of two electrode layers. One layer is used to emit electrical signals, and the other layer is used to receive electrical signals. Each layer is composed of a number of conductive line modules arranged at uniform intervals. The conductive line modules are connected with leads, and the other ends of the leads are connected to the controller for signal transmission and power supply. Due to the cancellation of the touch screen border, the leads originally arranged within the border need to be arranged in the gaps between the conductive line modules, and crosstalk occurs between the leads and the adjacent conductive line modules on both sides, making the screen unable to be accurately touched.
[0046] To solve the above problems, in this application, a reduction structure is set in the cross - region of the conductive line modules of the two layers to reduce the influence of crosstalk signals, thereby improving the touch accuracy of the screen.
[0047] Embodiment 1
[0048] As Figure 1-8 shown, this application proposes a display module, including:
[0049] A number of first conductive elements 1, which are arranged along a first direction to form a first functional layer 11;
[0050] A number of second conductive elements 2, which are arranged along a second direction perpendicular to the first direction to form a second functional layer 21, and the first functional layer 11 and the second functional layer 21 are stacked;
[0051] Wherein, a reduction structure 3 capable of reducing the induced coupling signal is provided in the cross - region of each first conductive element 1 and the corresponding second conductive element 2 on the first functional layer 11 and / or the second functional layer 21.
[0052] Specifically, the first conductive element 1 and the second conductive element 2 are made of the same conductive material, which can be metal mesh, ITO (indium tin oxide), nano - silver, etc.
[0053] It can be understood that if the first direction is horizontal, the second direction is vertical; if the first direction is vertical, the second direction is horizontal.
[0054] In this embodiment, the first direction is vertical and the second direction is horizontal. Taking the first conductive element 1 and the second conductive element 2 being made of ITO as an example, the ITO conductive coating has two layers, which are respectively arranged on the opposite sides of the insulating substrate layer, and the two conductive coatings are etched into conductive line modules with different arrangement patterns.
[0055] Among them, the conductive line module on one side of the insulating substrate layer can be the first conductive element 1. The first conductive element 1 is a strip - shaped part, extending horizontally, and a plurality of first conductive elements 1 are arranged at intervals along the vertical direction in sequence to form the first functional layer 11. The first functional layer 11 can be an emission layer for emitting electrical signals. Or, it can also be a receiving layer for receiving electrical signals.
[0056] The conductive line module on the other side of the insulating substrate layer can be the second conductive element 2. The second conductive element 2 is a strip-shaped member that extends longitudinally, and a plurality of second conductive elements 2 are arranged in sequence along the transverse direction to form a second functional layer 21. The second functional layer 21 can correspond to the first functional layer 11 and be a receiving layer for receiving electrical signals, or the second functional layer 21 can also be a transmitting layer for transmitting electrical signals.
[0057] The insulating substrate layer is disposed between the first functional layer 11 and the second functional layer 21 to prevent electrical signal interference between the conductive elements on the two functional layers. Among them, the material of the insulating substrate layer can be glass or plastic.
[0058] Among them, a plurality of overlapping regions are formed by laminating a plurality of first conductive elements 1 extending transversely and a plurality of second conductive elements 2 extending longitudinally. A reduction structure 3 is disposed in the overlapping region to reduce the coupled signal, that is, the induced capacitance, sensed in the overlapping region.
[0059] The reduction structure 3 can be disposed on the first conductive element 1 of the first functional layer 11, can also be disposed on the second conductive element 2 of the second functional layer 21, or can be disposed on both the first conductive element 1 and the second conductive element 2 at the same time.
[0060] The form of the reduction structure 3 can be an opening, a notch, a hole, or a slot hole. The specific shape can be a semicircle, a semi-ellipse, a rectangle, a trapezoid, or an irregular geometric shape. By the reduction structure 3, the total area after the first conductive element 1 and the second conductive element 2 are overlapped is reduced to reduce crosstalk between the lead and the first conductive element 1 or the second conductive element 2 when internally connecting leads, thereby reducing the accuracy of the touch screen.
[0061] Among them, a ground layer is also provided between or around the first conductive elements 1 and between or around the second conductive elements 2. The setting of the ground layer is to reduce electromagnetic interference between electronic components and the stability of touch control. The ground layer disposed on the periphery is usually located at the edge or periphery of the touch screen and surrounds the entire touch screen, and can serve as a large shielding ring to reduce the influence of external interference on the touch screen. The ground layer disposed between the first conductive element 1 or the second conductive element 2 is used to reduce crosstalk between the conductive elements.
[0062] It can be understood that the internal layout of the lead is such that in any one of the first functional layer 11 and the second functional layer 21, the lead is introduced along the gap between two conductive elements and penetrates the insulating substrate layer to connect with the other functional layer using the lead in the overlapping area. The connection point of the lead with the functional layer will generate crosstalk signals with adjacent conductive elements in the overlapping area. By using the above-mentioned reduction structure 3, the capacitive signals generated by the functional layer can be weakened, and the weakened signals correspond to the crosstalk signals to balance the coupling signals, thereby improving the touch accuracy of the screen.
[0063] In this application, by setting a reduction structure on the first conductive element and / or the second conductive element, the crosstalk amount and the induction amount are balanced, ensuring excellent touch performance of the touch screen.
[0064] In some embodiments, the first conductive element 1 is used to transmit an electrical signal, and the second conductive element 2 is used to receive an electrical signal; or, the second conductive element 2 is used to transmit an electrical signal, and the first conductive element 1 is used to receive an electrical signal.
[0065] It can be understood that if the first functional layer 11 can be a transmitting layer and the second functional layer 21 is a receiving layer, then the first conductive element 1 constituting the first functional layer 11 is a transmitting electrode, and the second conductive element 2 constituting the second functional layer 21 is a receiving electrode.
[0066] If the first functional layer 11 can be a receiving layer and the second functional layer 21 is a transmitting layer, then the first conductive element 1 constituting the first functional layer 11 is a receiving electrode, and the second conductive element 2 constituting the second functional layer 21 is a transmitting electrode.
[0067] Among them, the overlapping area can be formed on the first conductive element 1 or can also be formed on the second conductive element 2.
[0068] In some embodiments, the display module further includes:
[0069] A plurality of first leads 12 correspondingly connected to the first ends of a plurality of first conductive elements 1, and a plurality of second leads 22 that overlap with the second conductive elements 2 in the overlapping areas of the plurality of second conductive elements 2. The overlapping area is the cross area formed between each second conductive element 2 and the corresponding first conductive element 1;
[0070] Or,
[0071] A plurality of second leads 22 correspondingly connected to the second ends of a plurality of second conductive elements 2, and a plurality of first leads 12 that overlap with the first conductive elements 1 in the overlapping areas of the plurality of first conductive elements 1. The overlapping area is the cross area formed between each first conductive element 1 and the corresponding second conductive element 2;
[0072] Specifically, the first end portion of the first conductive element 1 can be the end close to the touch screen sensor and the touch screen controller integrated circuit. The specific setting position can be the lower side, left side or right side of the display screen, etc. The sensor is responsible for detecting touch events, and the integrated circuit can be responsible for processing signals and sending touch data to the system side of the host. The two cooperate to enable the touch screen to detect and respond to user touch inputs.
[0073] Among them, the first lead 12 is connected to the first conductive element 1 in a one-to-one correspondence. The first lead 12 can be arranged horizontally as a row electrode lead or vertically as a column electrode lead. If the overlapping area is set on the second conductive element 2, at this time, the second lead 22 is connected to the second conductive element 2 through the overlapping area in a one-to-one correspondence.
[0074] Among them, for the overlapping area formed by the intersection of each second conductive element 2 and the corresponding first conductive element 1, the intersection method can be the overlapping area of the second conductive element 2 extending horizontally in the first row and the first conductive element 1 extending vertically in the first column, or the overlapping area of the second conductive element 2 extending vertically in the first column and the first conductive element 1 extending horizontally in the first row; and they are arranged in sequence, which can be understood in the form of 1×1, 2×2, 3×3... Or, the first end portion of the second conductive element 2 can be the end close to the touch screen sensor and the touch screen controller integrated circuit. The specific setting position can be the lower side, left side or right side of the display screen, etc.
[0075] Among them, the second lead 22 is connected to the second conductive element 2 in a one-to-one correspondence. The second lead 22 can be arranged horizontally as a row electrode lead or vertically as a column electrode lead.
[0076] If the overlapping area is set on the first conductive element 1, at this time, the second lead 22 is connected to the first conductive element 1 through the overlapping area in a one-to-one correspondence.
[0077] Among them, for the overlapping area formed by the intersection of each first conductive element 1 and the corresponding second conductive element 2, the intersection method can be the overlapping area of the first conductive element 1 extending horizontally in the first row and the second conductive element 2 extending vertically in the first column, or the overlapping area of the first conductive element 1 extending vertically in the first column and the second conductive element 2 extending horizontally in the first row; and they are arranged in sequence, which can be understood in the form of 1×1, 2×2, 3×3...
[0078] In some embodiments, the display module further includes: a first sensor connected to a plurality of first leads 12 and a plurality of second leads 22. The first sensor is used to transmit the coupling signal sensed by the first conductive element 1 or the second conductive element 2 to the first processor of the display module to identify touch events on the display module.
[0079] Specifically, the first sensor is a touch sensor, which is used to detect a user's touch input and convert the input into an electrical signal.
[0080] When the display screen is touched, the capacitance of the electrode array formed by the first conductive element 1 and the plurality of second conductive elements 2 stacked vertically will change, and the touch sensor determines the touch position by measuring the capacitance change.
[0081] The first lead 12 is used to connect the first conductive element 1 with the first processor, and the second lead 22 is used to connect the second conductive element 2 with the first processor to transmit electrical signals. The first processor may be a touch screen controller or other processors, such as MCU or SCALAR.
[0082] In some embodiments, the trimming structure 3 includes at least one hole disposed in the overlapping region of the first conductive element 1 and / or at least one hole disposed in the overlapping region of the second conductive element 2 .
[0083] Specifically, the reduction structure 3 can be formed in the overlapping area of the first conductive element 1, and the overlapping area is
[0084] The overlapping area is formed by the first conductive element 1 and the second conductive element 2 being stacked and intersected, and one or more holes are provided on the overlapping area, and the holes are used for the second lead 22 to penetrate and connect with the second conductive element 2.
[0085] The cutting structure 3 can be formed in the overlapping area of the second conductive element 2, which is formed by the overlapping area where the second conductive element 2 and the first conductive element 1 are stacked and intersected, and one or more holes are provided on the overlapping area, which are used for the first lead 12 to penetrate and connect with the first conductive element 1.
[0086] Furthermore, the above-mentioned reduction structure 3 can be formed simultaneously in the overlapping region of the first conductive element 1 and the overlapping region of the second conductive element 2 .
[0087] In some embodiments, the subtractive structures 3 disposed on two adjacent first conductive elements 1 have different size parameters, and / or the subtractive structures 3 disposed on two adjacent second conductive elements 2 have different size parameters.
[0088] Specifically, taking the first conductive element 1 as an example, the second lead 22 is arranged on the first functional layer 11 and is located between two adjacent first conductive elements 1, and is used to connect the second conductive element 2. Since each second lead 22 is arranged at a different position of the first functional layer 11, the crosstalk signal generated by the second lead 22 is different in size, and the corresponding coupling signal is reduced by the reduction structure 3 with different size parameters to adapt to the crosstalk signal and achieve the effect of signal balance. Among them, the total area or total volume of the hole or notch can be different, so as to reduce the corresponding coupling signal.
[0089] In some embodiments, a size parameter of the first reduction structure 3 provided on the first functional layer 11 is smaller than a size parameter of the second reduction structure 3 provided, and the first conductive element 1 where the first reduction structure 3 is located is closer to the first side of the display module where the first sensor is provided than the first conductive element 1 where the second reduction structure 3 is located; and / or a size parameter of the third reduction structure 3 provided on the second functional layer 21 is smaller than a size parameter of the fourth reduction structure 3 provided, and an intersection area formed by the second conductive element 2 where the third reduction structure 3 is located and the corresponding first conductive element 1 is closer to the first side of the display module where the first sensor is provided than the intersection area formed by the second conductive element 2 where the fourth reduction structure 3 is located and the corresponding first conductive element 1.
[0090] It can be understood that when the first reduction structure 3 of the first functional layer 11 is located on a side of the first conductive element 1 closer to the first sensor compared to the second reduction structure 3, the length of the lead connected to the position of the first reduction structure 3 is shorter, and therefore the amount of crosstalk generated is smaller, making the area or volume of the first reduction structure 3 smaller than that of the second reduction structure 3.
[0091] When the third reduction structure 3 of the second functional layer 21 is located on a side of the second conductive element 2 closer to the first sensor compared to the fourth reduction structure 3, the length of the lead connected to the position of the third reduction structure 3 is shorter, so the amount of crosstalk generated is smaller, making the area or volume of the third reduction structure 3 smaller than that of the fourth reduction structure 3.
[0092] In some embodiments, the reduction structure 3 includes a hole disposed at least one of an edge, an interior, and an exterior of the overlapping region of the first conductive element 1 and / or the second conductive element 2 .
[0093] Specifically, the reduction structure 3 can be disposed at the edge of the overlapping region of the first conductive element 1, in the form of a notch, can be disposed at the middle position of the overlapping region, in the form of a hollowed-out hole, and can also be disposed outside the overlapping region, in the form of a hole. Similarly, the reduction structure 3 can be disposed at the edge of the overlapping region of the second conductive element 2, in the form of a notch, can be disposed at the middle position of the overlapping region, in the form of a hollowed-out hole, and can also be disposed outside the overlapping region, in the form of a hole.
[0094] In some embodiments, the fifth reduction structure 3 provided on the first conductive element 1 is located within the region surrounded by three adjacent first conductive elements 1 and a second conductive element 2 that intersects with the middle one of the three adjacent ones; and / or, the sixth reduction structure 3 provided on the second conductive element 2 is located within the region surrounded by three adjacent second conductive elements 2 and a first conductive element 1 that intersects with the middle one of the three adjacent ones.
[0095] Specifically, the first conductive element 1 is provided with a fifth reduction structure 3, and the fifth reduction structure 3 is located within the region surrounded by three adjacent first conductive elements 1 extending horizontally or vertically, and the middle first conductive element 1 and the second conductive element 2 arranged in a stacked manner. The second conductive element 2 is provided with a sixth reduction structure 3, and the sixth reduction structure 3 is located within the region surrounded by three adjacent second conductive elements 2 extending vertically or horizontally, and the middle second conductive element 2 and the first conductive element 1 arranged in a stacked manner.
[0096] In some embodiments, the dimensional parameters of the reduction structure 3 are matched with the target crosstalk amount, and the target crosstalk amount is the crosstalk amount between the second leads 22 of the first conductive element 1 and the second conductive element 2 or the crosstalk amount between the first leads 12 of the second conductive element 2 and the first conductive element 1.
[0097] Specifically, the dimensional parameters of the reduction structure 3 can be the coupling signal corresponding to the total area or total volume of the hollowed-out hole or notch, which is the same as the crosstalk amount between the second leads 22 of the first conductive element 1 and the second conductive element 2 or the crosstalk amount between the first leads 12 of the second conductive element 2 and the first conductive element 1, so as to achieve the effect of signal amount balance and make the touch signal not be interfered by the crosstalk amount.
[0098] It should be noted that the dimensional parameters of the reduction structure are determined according to the actual crosstalk amount, and there are no restrictions on the length and width here.
[0099] Take Figure 2 the row electrode (the conductive element extending horizontally) provided with the reduction structure 3 as an example. Theoretically, the length will not exceed the width of 3 column electrodes (the conductive elements extending vertically), and the width will not exceed the width of 1 row electrode; Take Figure 3Taking the reduction structure 3 provided for the column electrodes (longitudinally extending conductive elements) as an example, theoretically, the length will not exceed the width of 3 row electrodes (transversely extending conductive elements), and the width will not exceed the width of 1 column (longitudinally extending conductive element) electrode.
[0100] For the signal amounts corresponding to different size parameters of the reduction structure 3, a basic database is established based on the measured crosstalk amount and induction amount, and a mathematical model of the relationship trend between the reduction amount and the signal is established to guide the design. Subsequently, it can also be further optimized according to the measured values to achieve the optimal reduction amount and realize the optimal performance.
