[0032] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments 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.

[0033] As mentioned earlier, thin cover plates lose some impact strength. For example, ultra-thin flexible glass (UTG) poses a risk of damage during use. Consequently, cover plates with varying thicknesses, such as ultra-thin flexible glass (UFG), have emerged, which can be used in foldable screens. However, using cover plates with varying thicknesses can result in low touch accuracy.

[0034] In this regard, the present disclosure provides a touch display module. Figure 1 is a structural diagram of a touch display module 1000 according to an exemplary embodiment. Figure 1 The touch display module 1000 includes:

[0035] Display assembly 12, including touch sensing layer 20;

[0036] The cover plate 10 covers the display surface of the display assembly 12 and includes a first area 101 and a second area 102. The thickness of the cover plate in the first area 101 is different from the thickness of the cover plate in the second area 102. The first area corresponds to the first display area of the display assembly, and the second area corresponds to the second display area of the display assembly.

[0037] The touch sensing layer 20 includes a first sensing area 201 for sensing a touch applied to the first area 101 and a second sensing area 202 for sensing a touch applied to the second area 102. The sensing units 203 in the first sensing area 201 and the second sensing area 202 are arranged differently, and the arrangement is related to the thickness of the cover.

[0038] In the embodiments of the present disclosure, the touch display module 1000 can be used in electronic devices such as mobile phones, tablet computers, or wearable devices, and provides both display and touch functions. The touch display module 1000 can be a capacitive touch display module or a resistive touch display module, and the embodiments of the present disclosure are not limited thereto.

[0039] In the disclosed embodiment, the touch display module 1000 includes a display assembly 12 and a cover plate 10 disposed on the display assembly 12. The cover plate 10 can be made of glass, transparent polyimide, or plastic. The cover plate 10 protects the display assembly 12 and adjusts the display effect by changing the reflectivity and / or transmittance of light. The display assembly 12 can be based on a liquid crystal display (LCD) or an organic light-emitting diode (OLED) display, etc., and the disclosed embodiment does not impose any limitations thereto.

[0040] In the disclosed embodiment, the cover plate 10 includes a first area 101 and a second area 102. The first and second areas 101, 102 correspond to different cover plate thicknesses. The first area 101 corresponds to the first display area of the display assembly 12, and the second area 102 corresponds to the second display area of the display assembly 12. The display content in the first and second display areas is visible through the cover plate 10 to the user. The number of first and second areas 101, 102 is not limited; the cover plate 10 may include one or more first areas 101 as well as one or more second areas 102.

[0041] In some embodiments, the cover plate 10 includes a first region 101 and a plurality of second regions 102 distributed circumferentially around the first region 101 .

[0042] In the disclosed embodiment, the first area 101 may be located at the center of the cover plate 10, and the plurality of second areas 102 may be distributed circumferentially around the first area 10. For example, the plurality of second areas 102 may be distributed on both sides of the first area 10, or around the first area 10. The cover plate 10 may be designed with unequal thicknesses to achieve a better visual sense of layering or three-dimensionality. Furthermore, the unequal thickness design may also enable folding in thinner areas. For example, if the second areas 102 support folding, a touch display module supporting multiple foldable screens may be realized.

[0043] In some embodiments, the thickness of the cover plate of the first area 101 is less than the thickness of the cover plate of each of the second areas 102, and the cover plate of the first area 101 supports folding. In the embodiment of the present disclosure, the cover plate 10 can be a UFG cover plate.

[0044] In the embodiment of the present disclosure, the display component 12 supports both display and touch control. The display component 12 includes a touch sensing layer 20. The touch sensing layer 20 includes a first sensing area 201 for sensing touch in the first area 101, and a second sensing area 202 for sensing touch in the second area 102. It should be noted that the sensing units 203 in the first sensing area 201 and the second sensing area 202 can be formed based on electrodes, resistors, etc. The first sensing area 201 and the second sensing area 202 can include one or more sensing units 203.

[0045] Taking a capacitive screen as an example, the touch sensing layer includes multiple sensing units (unit cells). These units are typically created by arranging multiple electrodes in a specific pattern, connecting them through circuits, and processing algorithms. The sensing electrodes in the touch sensing layer are arranged in a specific pattern on a flexible or rigid substrate to maximize touch sensitivity and accuracy while minimizing false touches and noise interference. Electrodes are the basic elements of the sensing layer.

[0046] Figure 2 This is an example diagram of the arrangement of electrodes in a capacitive screen in the related art, such as Figure 2 As shown in the figure, 220L is an example of the electrode arrangement in the capacitive screen. The electrodes are arranged regularly, and the distance and size between electrodes in different areas are the same. Among them, 2203 shows one of the sensing units. As shown in the enlarged figure on the right, RX is the vertical electrode, TX is the horizontal electrode, and the distance between Tx and Rx is d. TX and RX can be isolated from each other by bridging.

[0047] Typically, both TX and RX are connected to the touch control chip (Integrated Circuit, IC). During actual touch sensing, the coupling between TX and RX is calculated. TX can be the transmitting electrode, and RX can be the receiving electrode. The touch control IC sends a drive signal to TX. Based on the drive signal, RX monitors current changes and feeds this current change back to the touch control IC via TX. If the current changes, the touch control IC calculates the capacitance change based on this current change. The touch position is determined by the position of TX and RX where the current change was detected.

[0048] It should be noted that the touch IC needs to detect the initial current when there is no touch, so as to subsequently determine whether there is a current change. When a finger presses, the finger forms another capacitor with TX and RX respectively. The finger is grounded, resulting in a decrease in the charge on TX and RX, and a decrease in the capacitance between Tx and Rx. When there is no touch, the original capacitance value is C = εS / 4πkd, where k is the electrostatic constant; ε is the dielectric constant, which is related to the medium between TX and RX; S is the facing area of ​​Tx and Rx, which is determined by the area of ​​TX and RX; d is the distance between Tx and Rx. When there is a touch, ε actually refers to the stacking between the display cover where the finger acts and the touch sensing layer, and d is actually the distance between the finger and the electrode.

[0049] It is understandable that based on Figure 2 In the arrangement shown, when there is no touch, the initial capacitance is the same; however, when there is touch, the dielectric constant ε of different touch areas will be different due to the influence of the cover thickness, resulting in different capacitances detected during touch. That is, the sensing units in different touch areas have different touch sensitivity capabilities, and the corresponding different sensing areas have inconsistent changes in the signal. For example, when the user slides on the display, there will be a phenomenon similar to the frozen screen where the touch does not follow the hand, or ghost points such as the touch response position not matching the actual touch position. Of course, for non-capacitive screens, such as resistive screens, changes in the thickness of the glass cover may affect the sensitivity of the resistance change between the two conductive layers. That is, the thickness of the glass cover will also make the sensing capabilities of the sensing areas with different cover thicknesses different.

[0050] In this regard, in the embodiment of the present disclosure, the arrangement of the sensing units 203 in the first sensing area 201 and the second sensing area 202 is different, and the arrangement is related to the thickness of the cover plate. Therefore, through different arrangement methods, the influence of different cover plate thicknesses can be comprehensively considered. On this basis, the difference in sensing capabilities of the sensing units 203 in the first sensing area 201 and the second sensing area 202 can be reduced. For example, if the sensing capabilities are the same, then when the user touches the first area 201 and the second area 202 with different cover plate thicknesses, the touch display module can give the same touch response, thereby reducing screen freezing and ghost point phenomena.

[0051] In some embodiments, the sensing units 203 in the first sensing area 201 and the second sensing area 202 both include vertical first sensing electrodes and horizontal second sensing electrodes. The arrangement of the first sensing electrodes and the second sensing electrodes in the first sensing area 201 is different from the arrangement of the first sensing electrodes and the second sensing electrodes in the second sensing area 202.

[0052] In the disclosed embodiment, the touch display module 1000 is a capacitive sensing module. The first sensing electrodes and second sensing electrodes included in the sensing units 203 are arranged differently in different sensing areas. For example, the facing areas S and Rx can be different, or the distance d between Tx and Rx can be different. By varying the facing areas S and d, consistent touch sensing can be achieved across touch areas of varying cover thicknesses when a touch is applied.

[0053] Because different cover plate thicknesses can lead to different dielectric constants, the dielectric constant directly affects capacitance calculations. Therefore, in the disclosed embodiments, the arrangement is associated with the cover plate thickness, and specific calculations, such as the facing area S between the first sensing electrode and the second sensing electrode, and / or the distance d between the first sensing electrode and the second sensing electrode, can be performed based on the dielectric constants corresponding to different cover plate thicknesses.

[0054] In the embodiment of the present disclosure, the material of the sensing electrode may be indium tin oxide or metal grid wire, or other materials such as nano-silver nanowire, graphene, etc., which is not limited in the embodiment of the present disclosure.

[0055] It can be understood that in the embodiments of the present disclosure, for the capacitive screen, the influence of different cover thicknesses on the sensing area on the sensing is reduced by setting different electrode arrangements in different sensing areas, that is, the touch accuracy is improved from the hardware level, which can take into account the touch response speed compared to the software tuning method.

[0056] In some embodiments, the relationship between the first sensing area between the first sensing electrode and the second sensing electrode in the first sensing region 201 and the second sensing area between the first sensing electrode and the second sensing electrode in the second sensing region 202 is opposite to the relationship between the first dielectric constant and the second dielectric constant; wherein the first dielectric constant is associated with the thickness of the cover of the first region 101, and the second dielectric constant is associated with the thickness of the cover of the second region 102.

[0057] In the embodiment of the present disclosure, the relationship between the first sensing area between the sensing electrodes in the first sensing region 201 and the second sensing area between the sensing electrodes in the second sensing region 202 is associated with the dielectrics stacked under display cover plates of different cover plate thicknesses, that is, with the actual dielectric constant.

[0058] For example, if the first dielectric constant ε1 corresponding to the first region 101 is large, and the second dielectric constant ε2 corresponding to the second region 102 is small, then to ensure that the sensing capabilities of the sensing units 203 in the first region 101 and the second region 102 are the same, based on the aforementioned capacitance calculation formula, it can be seen that the size relationship between the first sensing area S1 and the second sensing area S2 is opposite to the size relationship between the first dielectric constant ε1 and the second dielectric constant ε2. In other words, when ε1>ε2, S1<S2.

[0059] It should be noted that the relationship between cover thickness and dielectric constant may not be positively or negatively correlated. When designing a touch display module, the sensing area between the sensing electrodes can be specifically designed based on the dielectric constant values actually measured at different cover thicknesses.

[0060] In some embodiments, the relationship between the first distance between the first sensing electrode and the second sensing electrode in the first sensing region 101 and the second distance between the first sensing electrode and the second sensing electrode in the second sensing region 102 is the same as the relationship between the first dielectric constant and the second dielectric constant; wherein the first dielectric constant is associated with the thickness of the cover plate of the first region, and the second dielectric constant is associated with the thickness of the cover plate of the second region.

[0061] For example, if the first dielectric constant ε1 corresponding to the first region 101 is large, and the second dielectric constant ε2 corresponding to the second region 102 is small, then to ensure that the sensing capabilities of the sensing units 203 in the first region 101 and the second region 102 are the same, based on the aforementioned capacitance calculation formula, it can be seen that the relationship between the first distance d1 and the second distance d2 is the same as the relationship between the first dielectric constant ε1 and the second dielectric constant ε2. That is, when ε1>ε2, d1 is set to be greater than d2.

[0062] It should be noted that the distance between the sensing electrodes can also be specifically designed based on the dielectric constant values actually measured for different cover thicknesses. Furthermore, in the disclosed embodiments, the sensing area and distance between the sensing electrodes can also be adjusted simultaneously based on the dielectric constant, so that the sensing units within the sensing areas corresponding to different touch zones have the same sensing capability, i.e., the same capacitance value (e.g., C1 = C2).

[0063] Figure 3 This is an example diagram of the arrangement of electrodes in a capacitive screen according to an embodiment of the present disclosure. Figure 3 As shown, 201 is the first sensing area, 202 is the second sensing area, and the distance between electrodes and the size of electrodes in different areas are different. Figure 2 The structure of the sensing unit 203 in the first sensing area 201 is shown in the enlarged diagram on the right. Figure 2 , the distance between TX and RX increases, and the sensing area S decreases.

[0064] In some embodiments, the first sensing area 201 and the second sensing area 202 each include a plurality of sensing units 203 , the first sensing electrodes in different sensing units 203 are arranged in an array, and the second sensing electrodes in different sensing units are arranged in an array.

[0065] In the disclosed embodiment, the plurality of first sensing electrodes and the plurality of second sensing electrodes in the touch display module 1000 are arranged in an array, so as to support multi-touch, greatly enriching the user's operating experience and making the operation more intuitive and convenient.

[0066] Figure 4 This is a structural example diagram of a touch display module in an embodiment of the present disclosure. Figure 5 This is an example diagram of a touch operation in the embodiment of the present disclosure. For the convenience of subsequent description, the following is based on Figure 4 and Figure 5 It should be noted that, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The structures with the same identifier belong to the same function.

[0067] In some embodiments, the display assembly 12 further includes a coating layer 30 and a light processing layer 40 located between the cover plate 10 and the touch sensing layer 20;

[0068] The coating layer 30 is located between the display cover plate 10 and the light processing layer 40 , wherein the coating thickness corresponding to the first area 101 is different from the coating thickness corresponding to the second area 102 ;

[0069] The light processing layer 40 is located between the coating layer 30 and the touch sensing layer 20 .

[0070] In the embodiment of the present disclosure, the coating layer 30 can improve the optical properties of the surface and increase the hardness of the display cover 10. Figure 4 As shown, the coating thickness corresponding to the first area 101 of the UFG display cover plate 10 is different from the coating thickness corresponding to the second area 102 , so that the dielectric constants between the display cover plate 10 and the touch sensing layer 20 are different.

[0071] In the disclosed embodiments, the light processing layer 40 may include a color filter or a polarizer. The color filter is used to decompose white light into the three primary colors of red, green, and blue to produce a color image. The polarizer is used to control the direction of light and ensure that it propagates correctly through the liquid crystal layer. In some designs, these two layers may be separate layers or integrated together.

[0072] In some embodiments, the display assembly 12 further includes:

[0073] Back plate layer 60;

[0074] The display emission layer 50 is located between the touch sensing layer 20 and the backplane layer 60 .

[0075] In the embodiment of the present disclosure, the backplane layer 60 may be a polyimide (PI) backplane layer. Polyimide is a high-performance polymer material with excellent high-temperature resistance, chemical corrosion resistance, and mechanical properties, and can provide structural support and stability for the display screen.

[0076] In the embodiment of the present disclosure, the display emission layer 50 may be an organic light emitting diode (AMOLED) display emission layer. The AMOLED display emission layer includes an organic material layer. When current passes through, these materials emit light to produce an image.

[0077] like Figure 5 As shown, based on the solution of the embodiment of the present disclosure, the touch is applied to the first area 101 and the second area 102, and the sensing units of the touch sensing layer 20 in the sensing area corresponding to the touch area have the same sensing capability, that is, Figure 5 The values of C1 and C2 are equal.

[0078] The present disclosure also provides an electronic device including the touch display module of any of the aforementioned embodiments. In the present disclosure, the electronic device includes a mobile phone, a tablet computer, or a smart wearable device, which is not limited to the present disclosure.

[0079] It is understandable that the touch display module can provide the same touch response, thereby reducing the occurrence of frozen screen and ghost point phenomena, and improving the user experience of using electronic devices.

[0080] In some embodiments, the electronic device includes a first shell and a second shell, wherein the first shell and the second shell support folding and unfolding; the first area 101 is located at the connection between the first shell and the second shell;

[0081] The second area 102 is provided at a position away from the connection point in the first shell and / or the second shell; the thickness of the cover plate of the first area 102 is smaller than the thickness of the cover plate of the second area 102 .

[0082] In the embodiment of the present disclosure, the electronic device is a folding screen device, and the first area 101 with a small cover thickness is located at the connection between the foldable first shell and the second shell, so that the electronic device is easy to fold; in addition, the second area 102 with a large cover thickness is located at a position away from the connection, so that it can provide better impact strength without affecting the folding, thereby extending the service life of the foldable electronic device.
