[0034] For ease of understanding, the positions, dimensions, and extents of the structures shown in the accompanying drawings and other materials may not represent actual positions, dimensions, and extents. Therefore, this disclosure is not limited to the positions, dimensions, and extents disclosed in the accompanying drawings and other materials. Detailed Implementation

[0035] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0036] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this disclosure or its application or use. That is, the structures and methods herein are shown in an exemplary manner to illustrate different embodiments of the structures and methods in this disclosure. However, those skilled in the art will understand that they merely illustrate exemplary ways that can be used to implement this disclosure, and not exhaustive ways. Furthermore, the drawings are not necessarily drawn to scale, and some features may be enlarged to show details of specific components.

[0037] In addition, techniques, methods and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods and equipment should be considered part of the specification.

[0038] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0039] In real-world usage scenarios, display device screens frequently break for various reasons. A broken screen severely impacts the user experience and the reliability of the display device. Therefore, it is necessary to inspect the screen condition of the display device to determine its overall state.

[0040] To this end, this disclosure provides a display device including a conductive trace disposed on the screen of the display device and extending along the edge of the screen, a signal transmitting module for transmitting a first electrical signal capable of being transmitted along the conductive trace to the conductive trace, and a signal receiving module for receiving a second electrical signal from the conductive trace. The second electrical signal can be used to determine the state of the screen of the display device (e.g., whether it is damaged), thereby enabling timely maintenance of the display device and improving the user experience.

[0041] The display device according to some embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It will be understood that the actual display device may have other components, but in order to avoid obscuring the key points of the present disclosure, these other components are not shown in the drawings and will not be discussed herein.

[0042] Additionally, it is understood that the term "screen" as used in this disclosure refers to the cover plate of a display device (e.g., a glass cover plate or a cover plate made of other materials), which is typically located on the outermost part of the display device and thus accessible to the user.

[0043] refer to Figure 1 This illustrates a schematic diagram of a display device 100 according to some embodiments of the present disclosure. For example... Figure 1 As shown, the display device 100 includes a screen 102 and conductive traces 104 disposed on the screen 102 and extending along the edge of the screen 102.

[0044] The conductive trace 104 can be formed of any suitable conductive material, such as a transparent conductive material. In some embodiments, the material of the conductive trace 104 may include at least one of silver ink and indium tin oxide (ITO).

[0045] In some embodiments, the line resistance value of the conductive trace 104 depends on the size of the screen 102 and the specific implementation of how to determine whether the screen 102 is damaged. In some examples, the maximum line resistance value of the conductive trace 104 does not exceed 30 kiloohms, for example, not exceeding 20 kiloohms.

[0046] In some embodiments, the spacing d1 and d2 between the conductive trace 104 and the edge of the screen 102 are between 1 mm and 5 mm, respectively. The conductive trace 104 may maintain substantially the same spacing with the edge of the screen 102 at various locations along the conductive trace 104.

[0047] As an illustrative example, the conductive traces in the above examples can be applied to screens ranging in size from 7 inches to 32 inches, in width or height from 100 mm to 800 mm, and with no thickness limitation. For example, conductive traces can be applied to screens with a thickness ranging from 0.55 mm to 4.0 mm, and the thickness can be unlimited if desired.

[0048] It is understandable that in practical use cases, the edges of a display screen are generally more prone to damage than the center. Therefore, it can be advantageous to set the conductive traces to extend along the edges of the screen. Of course, in other embodiments, the distance between the conductive traces and the screen edge can be increased to bring them closer to the screen center. The closer the conductive traces are to the screen center, the more severe the damage they may detect. Therefore, the distance between the conductive traces and the screen edge can be adjusted according to the damage detection requirements. In short, the specific position and shape (e.g., length, width) of the conductive traces can be adjusted according to actual needs.

[0049] Continue to refer to Figure 1 The display device 100 further includes a signal transmitting module 110 coupled to a first end 106 of the conductive trace 104 and a signal receiving module 112 coupled to a second end 108 of the conductive trace 104. Here, the signal transmitting module 110 is configured to transmit a first electrical signal to the conductive trace 104 via the first end 106, the first electrical signal being configured to be transmitted along the conductive trace 104; the signal receiving module 112 is configured to receive a second electrical signal from the conductive trace 104 via the second end 108, the second electrical signal being configured to determine whether the screen 102 is damaged.

[0050] In some examples, the signal transmitting module 110 may continuously or periodically transmit a first electrical signal to the conductive trace 104 via the first terminal 106. Correspondingly, the signal receiving module 112 may continuously or periodically receive a second electrical signal from the conductive trace 104 via the second terminal 108.

[0051] In some examples, the signal transmitting module 110 may transmit a voltage signal as a first electrical signal to the conductive trace 104 via a first terminal 106. Correspondingly, the signal receiving module 112 may receive another voltage signal as a second electrical signal from the conductive trace 104 via a second terminal 108. In some examples, the first and second electrical signals may be high-voltage signals or low-voltage signals having any suitable waveform (e.g., square wave, sine wave, etc.).

[0052] Because damage to the screen 102 can cause a gap, break, or accidental grounding of the conductive trace 104 in a corresponding portion (e.g., conductive debris from the conductive trace 104 electrically connects a portion of the conductive trace 104 to a ground wire). For example, if a gap appears in a corresponding portion of the conductive trace 104, it will cause a change in the second electrical signal received by the signal receiving module 112, thereby allowing the determination that the screen is damaged based on this change in the second electrical signal.

[0053] In some embodiments, the screen 102 is a touch screen, the signal transmitting module 110 is configured to transmit a first electrical signal during a screen detection cycle, and the signal receiving module 112 is configured to receive a second electrical signal during a screen detection cycle, which is outside the touch detection cycle used to detect whether the screen 102 is touched.

[0054] In some embodiments, such as Figure 1 As shown, the first end 106 and the second end 108 are opposite ends of the conductive trace 104. In such an embodiment, a first value for characterizing mutual capacitance can be determined, for example, based on a second electrical signal, and screen damage can be determined in response to the first value being less than a first preset threshold.

[0055] For example, signal transmitting module 110 can be the RX1 pin, and signal receiving module 112 can be the RX2 pin. In such an example, a digital voltage can be provided on the RX1 pin, and the charge received on the RX2 pin can be measured. The charge received on the RX2 pin is proportional to the mutual capacitance between the two pins. When the conductive trace between the two pins breaks, the mutual capacitance decreases, and therefore the charge received on the RX2 pin also decreases. Thus, screen damage can be detected by detecting the charge (second electrical signal) on the RX2 pin.

[0056] In some embodiments where the first end 106 and the second end 108 are opposite, the signal transmitting module 110 can be implemented as a first signal transceiver module 110, and the signal receiving module 112 can be implemented as a second signal transceiver module 112.

[0057] In this embodiment, the first signal transceiver module 110 is configured to transmit a first electrical signal to the conductive trace 104 via the first terminal 106 during a first transmission period in the first screen detection cycle, and the second signal transceiver module 112 is configured to receive a second electrical signal from the conductive trace 104 via the second terminal 108 during a first reception period in the first screen detection cycle. The second signal transceiver module 112 is also configured to transmit a third electrical signal to the conductive trace 104 via the second terminal 108 during a second transmission period in the second screen detection cycle. The third electrical signal is configured to be transmitted along the conductive trace 104. Furthermore, the first signal transceiver module 110 is configured to receive a fourth electrical signal from the conductive trace 104 via the first terminal 106 during a second reception period in the second screen detection cycle. The fourth electrical signal is configured to determine whether the screen 102 is damaged. The second screen detection cycle may occur after the first screen detection cycle.

[0058] In other words, during the first screen detection cycle, the electrical signal can be considered to be transmitted from the first end 106 of the conductive trace 104 to the second end 108, while during the subsequent second screen detection cycle, the electrical signal can be considered to be transmitted from the second end 108 of the conductive trace 104 to the first end 106. Thus, dual verification of screen damage detection can be achieved through the second and fourth electrical signals, improving the accuracy of screen damage detection. Furthermore, by exchanging the roles of the first signal transceiver module 110 and the second signal transceiver module 112 in transmitting / receiving electrical signals during the first and second screen detection cycles, the transmission directions of the electrical signals in the two screen detection cycles are reversed, thereby reducing the impact of the near-far effect on the screen damage detection results and further improving the accuracy of screen damage detection. In this paper, the near-far effect can refer to the fact that the distance along the conductive trace between the location where the conductive trace breaks due to screen damage and the end of the conductive trace coupled to the module used to receive the electrical signal will differ, resulting in different electrical signals received by the module (e.g., in terms of signal strength).

[0059] In some embodiments, multiple such first screen detection cycles and multiple such second screen detection cycles may occur alternately.

[0060] For example, refer to Figure 2 It shows that it is aimed at Figure 1 An exemplary signal timing diagram of the display device 100 includes multiple alternating first screen detection cycles T1 and second screen detection cycles T2. Furthermore, in the signal timing diagram herein, touch detection cycles can be indicated by black boxes and screen detection cycles by white boxes. Figure 2 As shown, the transmission and reception of electrical signals, which are the RX1 pin of the first signal transceiver module 110 and the RX2 pin of the second signal transceiver module 112, are performed in the screen detection cycles T1 and T2, which are outside the touch detection cycle T0 of the screen 102.

[0061] Specifically, in the first screen detection cycle T1, the RX1 pin sends a first electrical signal to the conductive trace 104 via the first terminal 106 during the first transmission period t11, and the RX2 pin receives a second electrical signal from the conductive trace 104 via the second terminal 108 during the first reception period t12; in the second screen detection cycle T2, which is later than the first screen detection cycle T1, the RX2 pin sends a third electrical signal to the conductive trace 104 via the second terminal 108 during the second transmission period t21, and the RX1 pin receives a fourth electrical signal from the conductive trace 104 via the first terminal 106 during the second reception period t22.

[0062] A similar effect to the above scheme can be achieved without switching the direction of electrical signal transmission in the conductive trace 104.

[0063] refer to Figure 3 This illustrates a schematic diagram of a display device 100A according to some embodiments of the present disclosure. For example... Figure 3 As shown, with Figure 1 Compared to the display device 100 shown, the conductive trace 104 is referred to herein as the first conductive trace 104, the signal transmitting module 110 is referred to herein as the first signal transmitting module 110, and the signal receiving module 112 is referred to herein as the first signal receiving module 112. The first signal transmitting module 110 is configured to transmit a first electrical signal to the first conductive trace 104 via the first terminal 106 during a first transmission period in the first screen detection cycle, and the first signal receiving module 112 is configured to receive a second electrical signal from the first conductive trace 104 via the second terminal 108 during a first reception period in the first screen detection cycle.

[0064] In this embodiment, with Figure 1 Compared to the display device 100 shown, the display device 100A further includes a second conductive trace 1042 disposed on the screen 102 and extending along the edge of the screen 102, the second conductive trace 1042 being separated from the first conductive trace 104. In some embodiments, the spacing between the first conductive trace 104 and the second conductive trace 1042 is in the range of 0.5 mm to 5 mm. The first conductive trace 104 may maintain substantially the same spacing with the second conductive trace 1042 at various locations along the first conductive trace 104. Other construction details of the second conductive trace 1042 can be similarly referred to the first conductive trace 104, and will not be elaborated here.

[0065] In this embodiment, the display device 100A further includes: a second signal transmitting module 118 coupled to a third terminal 114 of the second conductive trace 1042; and a second signal receiving module 120 coupled to a fourth terminal 116 of the second conductive trace 1042 opposite to the third terminal 114. Here, the second signal transmitting module 118 is configured to transmit a third electrical signal to the second conductive trace 1042 via the third terminal 114 during a second transmission period in the second screen detection cycle. The third electrical signal is configured to be transmitted along the second conductive trace 1042. The second signal receiving module 120 is configured to receive a fourth electrical signal from the second conductive trace 1042 via the fourth terminal 116 during a second reception period in the second screen detection cycle. The fourth electrical signal is configured to determine whether the screen 102 is damaged. The second screen detection cycle may occur after the first screen detection cycle.

[0066] In this embodiment, the transmission direction of the third electrical signal in the second conductive trace is the same as the transmission direction of the first electrical signal in the first conductive trace. Therefore, by setting two conductive traces, dual verification of screen damage detection can be achieved, thereby improving the accuracy of screen damage detection.

[0067] Alternatively, in some embodiments, the propagation direction of the third electrical signal in the second conductive trace is opposite to the propagation direction of the first electrical signal in the first conductive trace. This can be achieved, for example, by transposing the signals. Figure 3 The second signal transmitting module 118 and the second signal receiving module 120 are implemented in the system, such that the second signal transmitting module 118 is coupled to the fourth terminal 116 and the second signal receiving module 120 is coupled to the third terminal 114. Therefore, by making the transmission directions of the electrical signals in the two conductive traces opposite, the influence of the near-far effect on the screen damage detection results can be reduced, further improving the accuracy of screen damage detection.

[0068] For example, refer to Figure 4 It shows that it is aimed at Figure 3 An exemplary signal timing diagram of the display device 100A. (See example...) Figure 4 As shown, pin RX1 serves as the first signal transmitting module 110, pin RX2 serves as the first signal receiving module 112, pin RX4 serves as the second signal transmitting module 118, and pin RX3 serves as the second signal receiving module 120. The transmission of electrical signals from pin RX1 to pin RX4 is performed during screen detection cycles T1 and T2, outside of the touch detection cycle T0 of screen 102.

[0069] Specifically, in the first screen detection period T1, the RX1 pin sends a first electrical signal to the first conductive trace 104 via the first terminal 106 during the first transmission period t11, and the RX2 pin receives a second electrical signal from the first conductive trace 104 via the second terminal 108 during the first reception period t12; in the second screen detection period T2, which is later than the first screen detection period T1, the RX4 pin sends a third electrical signal to the second conductive trace 1042 via the third terminal 114 during the second transmission period t21, and the RX3 pin receives a fourth electrical signal from the second conductive trace 1042 via the fourth terminal 116 during the second reception period t22.

[0070] Similar to the second electrical signal, the fourth electrical signal can be used to determine whether the screen is damaged through mutual capacitance, but I won't go into details here.

[0071] For example, screen damage can be finally determined in response to both a second electrical signal and a fourth electrical signal indicating screen damage. In some embodiments, the second signal transmitting module 118 and the second signal receiving module 120 can be activated in response to determining screen damage based on the second electrical signal. That is, the activation of the second screen detection cycle can be triggered, thereby saving energy consumption of the display device 100.

[0072] Alternatively, screen damage can be ultimately determined in response to either the second or fourth electrical signal indicating screen damage. In some embodiments, the second signal transmitting module 118 and the second signal receiving module 120 can be disabled in response to determining that the screen is not damaged based on the second electrical signal. That is, the disabling of the second screen detection cycle can be triggered, thereby saving energy consumption of the display device 100.

[0073] refer to Figure 5 This illustrates a schematic diagram of a display device 100B according to other embodiments of the present disclosure. For example... Figure 5 As shown, with Figure 1 Compared to the display device 100 shown, the signal transmitting module and the signal receiving module are jointly implemented as a signal transceiver module 140, which is coupled to one end 132 of a conductive trace 130 disposed on the screen 102 and extending along the edge of the screen 102. The construction details of the conductive trace 130 can be similarly referred to the conductive trace 104, and will not be described in detail here.

[0074] Here, the signal transceiver module 140 is configured to send a first electrical signal to the conductive trace 130 via terminal 132 during the transmission period of the screen detection cycle and receive a second electrical signal from the conductive trace 130 via terminal 132 during the reception period of the same screen detection cycle. The second electrical signal is configured to determine whether the screen is damaged. For example, a second value characterizing self-capacitance can be determined based on the second electrical signal, and the screen 102 can be determined to be damaged in response to the second value being less than a second preset threshold. Furthermore, the conductive trace 130 can be determined to be short-circuited in response to the second value being greater than a third preset threshold, wherein the third preset threshold is greater than the second preset threshold. When screen damage causes the conductive trace 130 to break and ground, the self-capacitance increases. Thus, by setting the second and third preset thresholds, it is also possible to determine whether the circuit fault caused by screen damage is an open circuit or a short circuit, thereby refining the detection results and providing more accurate information for technicians.

[0075] For example, the signal transceiver module 140 can be the RX1 pin. In such an example, the capacitance between the RX1 pin and ground can be measured, which is called self-capacitance. When the conductive trace connected to the RX1 pin is broken, the self-capacitance decreases, and when the conductive trace is accidentally shorted to ground due to conductive debris, the self-capacitance increases. Thus, screen damage can be detected by detecting a second electrical signal at the RX1 pin.

[0076] refer to Figure 6 It shows that it is aimed at Figure 5 An exemplary signal timing diagram of the display device 100B, which includes multiple screen detection cycles T1. For example... Figure 6As shown, the transmission and reception of electrical signals by the RX1 pin of the signal transceiver module 140 are both performed during the screen detection cycle T1, which is outside the touch detection cycle T0 of the screen 102. Specifically, during the screen detection cycle T1, the RX1 pin transmits a first electrical signal to the conductive trace 130 via terminal 132 during the transmission period t11 and receives a second electrical signal from the conductive trace 130 via terminal 132 during the reception period t12.

[0077] refer to Figure 7 This illustrates a schematic diagram of a display device 100C according to some embodiments of the present disclosure. For example... Figure 7 As shown, with Figure 5 Compared to the display device 100B shown, the conductive trace 130 is referred to herein as the first conductive trace 130, and the signal transceiver module 140 is referred to herein as the first signal transceiver module 140. The first signal transceiver module 140 is configured to transmit a first electrical signal to the first conductive trace 130 via terminal 132 during a first transmission period in the first screen detection cycle, and to receive a second electrical signal from the first conductive trace 130 via terminal 132 during a first reception period in the first screen detection cycle.

[0078] Continue to refer to Figure 7 ,and Figure 5 Compared to the display device 100B, the display device 100C further includes a second conductive trace 1302 disposed on the screen 102 and extending along the edge of the screen 102, the second conductive trace 1302 being separated from the first conductive trace 130. In some embodiments, the spacing between the first conductive trace 130 and the second conductive trace 1302 is in the range of 0.5 mm to 5 mm. The first conductive trace 130 may maintain substantially the same spacing with the second conductive trace 1302 at various locations along the first conductive trace 130. Other construction details of the second conductive trace 1302 can be similarly referred to the first conductive trace 130, and will not be elaborated here.

[0079] In this embodiment, the display device 100C further includes a second signal transceiver module 150 coupled to one end 134 of the second conductive trace 1302. Here, the second signal transceiver module 150 is configured to transmit a third electrical signal to the second conductive trace 1302 via the end 134 during a second transmission period in the second screen detection cycle. The third electrical signal is configured to be transmitted along the second conductive trace 1302. The second signal transceiver module 150 is also configured to receive a fourth electrical signal from the second conductive trace 1302 via the end 134 during a second reception period in the second screen detection cycle. The fourth electrical signal is configured to determine whether the screen 102 is damaged. The second screen detection cycle can occur after the first screen detection cycle. Therefore, by setting the first and second conductive traces, dual verification of screen damage detection can be achieved, thereby improving the accuracy of screen damage detection.

[0080] refer to Figure 8 It shows that it is aimed at Figure 7 An exemplary signal timing diagram of the display device 100C. (See example...) Figure 8 As shown, the transmission and reception of electrical signals by the RX1 pin of the first signal transceiver module 140 and the RX2 pin of the second signal transceiver module 150 are performed during screen detection cycles T1 and T2, which are outside the touch detection cycle T0 of the screen 102. Specifically, in the first screen detection cycle T1, the RX1 pin transmits a first electrical signal to the first conductive trace 130 via terminal 132 during the first transmission period t11 and receives a second electrical signal from the first conductive trace 130 via terminal 132 during the first reception period t12; in the second screen detection cycle T2, which is later than the first screen detection cycle T1, the RX2 pin transmits a third electrical signal to the second conductive trace 1302 via terminal 134 during the second transmission period t21 and receives a fourth electrical signal from the second conductive trace 1302 via terminal 134 during the second reception period t22.

[0081] Similar to the second electrical signal, the fourth electrical signal can be used to determine whether the screen is damaged via self-capacitance, but I won't go into details here.

[0082] For example, screen damage can be finally determined in response to both a second electrical signal and a fourth electrical signal indicating screen damage. In some embodiments, the second signal transceiver module 150 can be activated in response to determining screen damage based on the second electrical signal. That is, the activation of the second screen detection cycle can be triggered, thereby saving power consumption of the display device 100.

[0083] Alternatively, screen damage can be definitively determined in response to either the second or fourth electrical signal indicating screen damage. In some embodiments, the second signal transceiver module 150 can be disabled in response to determining that the screen is not damaged based on the second electrical signal. That is, the disabling of the second screen detection cycle can be triggered, thereby saving power consumption of the display device 100.

[0084] Continue to refer to Figure 7 In some embodiments, the transmission direction of the third electrical signal in the second conductive trace 1302 is opposite to the transmission direction of the first electrical signal in the first conductive trace 130. This reduces the impact of the proximity effect on the screen damage detection results, thereby improving the accuracy of screen damage detection. With the dual conductive traces, the screen damage location can be further from the end 134 of the second conductive trace 1302 when it is closer to the end 132 of the first conductive trace 130, and further from the end 132 of the first conductive trace 130 when it is farther from the end 134 of the second conductive trace 1302. Therefore, for example, screen damage can be ultimately determined in response to either the second or fourth electrical signal indicating screen damage, thus avoiding missed detections caused by the proximity effect.

[0085] In other embodiments, the transmission direction of the third electrical signal in the second conductive trace 1302 may be the same as the transmission direction of the first electrical signal in the first conductive trace 130.

[0086] In some embodiments, the display device is a touch display device. (See reference) Figure 9 This illustration shows a schematic exploded view of a touch display device 300 according to some embodiments of the present disclosure, wherein a first direction indicates the direction in which a user looks from outside the screen to inside the screen. The side furthest from the user can be referred to as the far side, and the side closer to the user as the near side. Figure 9 As shown, in this embodiment, the conductive trace 104 can be disposed on the far side of the screen 102 (i.e., inside the touch display device 300) for ease of manufacturing and aesthetics.

[0087] Continue to refer to Figure 9 In further embodiments, the touch display device 300 may include: a touch sensor layer 304 disposed on the far side of the screen 102; an insulating layer 302 disposed between the screen 102 and the touch sensor layer 304 to isolate the touch sensor layer 304 and the conductive trace 104, wherein the insulating layer 302 has conductive vias 308 electrically connected to a first end 106 and a second end 108 of the conductive trace 104, respectively; and a flexible cable 306 configured to be electrically connected to the conductive vias 308. Note that in embodiments where the first end and the second end are the same end, one conductive via 308 may be provided; while in embodiments where the first end and the second end are opposite ends, two conductive vias 308 may be provided.

[0088] In some embodiments, the projection of the touch sensor layer 304 onto the screen 102 falls within the area defined by the conductive traces 104. Therefore, screen damage detection via the conductive traces 104 has little or no impact on touch detection of the screen 102.

[0089] In some embodiments, the flexible cable 306 is also configured to be electrically connected to both the touch sensor membrane 304 and the conductive via 308. (See reference) Figure 10 This illustrates a schematic exploded view of a touch display device 300' according to some embodiments of the present disclosure. Figure 10 As shown, the flexible cable 306 is formed as a "Y"-shaped flexible cable. The flexible cable 306 may include a first end 3061 and a second end 3062, wherein the first end 3061 of the flexible cable 306 is configured to be electrically connected to the touch sensor layer 304 and the second end 3062 of the flexible cable 306 is configured to be electrically connected to the conductive via 308, thereby enabling touch detection and screen damage detection of the touch display device 300 via a single flexible cable.

[0090] As an illustrative example, the manufacturing steps of the touch display device 300 may include: (1) selecting a substrate glass and depositing an ITO film on the substrate glass to form an ITO flat glass, and cutting and grinding the ITO flat glass to customize the screen's dimensions; (2) etching the ITO film on the ITO flat glass to form ITO conductive traces extending along the edge of the screen; (3) printing black ink as an insulating layer and leaving through holes in the insulating layer; (4) printing conductive black ink near the through holes to form conductive through holes for electrically connecting flexible cables and ITO conductive traces; and (5) connecting flexible cables to the conductive through holes.

[0091] refer to Figure 11 This illustrates a schematic diagram of a display device 100D according to some embodiments of the present disclosure. For example... Figure 11 As shown, with Figure 1 Compared to the display device 100 shown, the display device 100D further includes a control module 402 coupled to the signal transmitting module 110 and the signal receiving module 112 and configured to execute the method 1000 described below, and a communication module 404 coupled to the control module 402 and configured to send a notification to the central management system 500 via the host 406 to report screen damage in response to determining screen damage. Thus, the central management system 500 can monitor the screen status of the display device 100D in a timely manner and, upon receiving a notification of screen damage, can promptly arrange repairs to the display device 100D, reducing losses caused by screen damage.

[0092] As an illustrative example, for a display device with touch functionality, the aforementioned signal transmitting / receiving / transmitting module, control module, and communication module can be jointly implemented in the touch processing chip (Touch IC) of the touch display device. For a display device without touch functionality, the aforementioned signal transmitting / receiving / transmitting module, control module, and communication module can be jointly implemented in the display processing chip of the display device (e.g., a Scaler (image scaling) microcontroller unit (MCU)). For example, one or more TX or RX pins of these chips can be used as the aforementioned signal transmitting / receiving / transmitting module.

[0093] This disclosure also provides a method for detecting the state of the screen of a display device, the method being executable by the display device described above. (Reference) Figure 12 This illustrates a flowchart of a method 1000 for detecting the state of a display device screen according to some embodiments of the present disclosure. Figure 12 As shown, method 1000 includes: at step S1002, sending a first electrical signal to a conductive trace via a first end disposed on the screen and extending along the edge of the screen, the first electrical signal being configured to be transmitted along the conductive trace; at step S1004, receiving a second electrical signal from the conductive trace via a second end of the conductive trace; and at step S1006, determining whether the screen is damaged based on the second electrical signal.

[0094] For example, when the screen is intact, although electrical signals may be affected by interference or loss during transmission along the conductive traces, this impact is negligible compared to the situation when the conductive traces are broken. Therefore, the second electrical signal can be considered essentially the same as the first electrical signal. When the screen is broken, the first electrical signal, after transmitting along the partially or completely broken conductive traces affected by the screen breakage, will exhibit significantly altered or even lost signal characteristics (e.g., signal strength, waveform, etc.), making the second electrical signal distinctly different from the first. Thus, the screen breakage can be determined based on the second electrical signal.

[0095] In some embodiments, the transmission of the first electrical signal occurs during the transmission period, and the reception of the second electrical signal occurs during the reception period, wherein the reception period is later than the transmission period.

[0096] In some embodiments, the first electrical signal may be a voltage signal, and the signal strength of the first electrical signal is not less than a preset voltage threshold. For example, the preset voltage threshold may be determined based on the loss of the first electrical signal during transmission along the conductive trace from the first end to the second end and the minimum detectable signal strength of the second electrical signal.

[0097] In some embodiments, the first end and the second end are opposite ends of the conductive trace. Next, several examples of method 1000 will be described with the first end and the second end being opposite ends of the conductive trace.

[0098] In some examples, determining whether the screen is damaged based on the second electrical signal includes: determining a first value for characterizing mutual capacitance based on the second electrical signal; and determining that the screen is damaged in response to the first value being less than a first preset threshold.

[0099] In some examples, during a first screen detection cycle, a first electrical signal is sent to a conductive trace via a first end and a second electrical signal is received from the conductive trace via a second end. In this embodiment, method 1000 may include: during a second screen detection cycle, sending a third electrical signal to the conductive trace via a second end and receiving a fourth electrical signal from the conductive trace via a first end, the third electrical signal being configured to be transmitted along the conductive trace; and determining whether the screen is damaged based on the fourth electrical signal, wherein the second screen detection cycle occurs after the first screen detection cycle. Thus, dual verification of screen damage detection can be achieved using the second and fourth electrical signals, improving the accuracy of screen damage detection.

[0100] In some examples, the aforementioned conductive trace is a first conductive trace. During a first screen detection cycle, a first electrical signal is sent to the first conductive trace via a first end and a second electrical signal is received from the first conductive trace via a second end. In this embodiment, method 1000 may further include: during a second screen detection cycle, sending a third electrical signal to the second conductive trace via a third end of the second conductive trace disposed on the screen and extending along the edge of the screen and separated from the first conductive trace, and receiving a fourth electrical signal from the second conductive trace via a fourth end of the second conductive trace opposite to the third end, wherein the third electrical signal is configured to be transmitted along the second conductive trace; and determining whether the screen is damaged based on the fourth electrical signal, wherein the second screen detection cycle occurs after the first screen detection cycle. Thus, the second electrical signal of the first conductive trace and the fourth electrical signal of the second conductive trace enable dual verification of screen damage detection, thereby improving the accuracy of screen damage detection.

[0101] Furthermore, in some examples, the propagation direction of the third electrical signal in the second conductive track is the same as the propagation direction of the first electrical signal in the first conductive track. In other examples, the propagation direction of the third electrical signal in the second conductive track is opposite to the propagation direction of the first electrical signal in the first conductive track.

[0102] In some embodiments, the first end and the second end are the same end of a conductive trace. Next, several examples of method 1000 will be described where the first end and the second end are the same end of a conductive trace.

[0103] In some examples, determining whether the screen is damaged based on the second electrical signal includes: determining a second value for characterizing self-capacitance based on the second electrical signal; and determining that the screen is damaged in response to the second value being less than a second preset threshold.

[0104] In some examples, determining whether the screen is damaged based on the second electrical signal may also include: determining that the conductive trace is short-circuited in response to the second value being greater than a third preset threshold, wherein the third preset threshold is greater than the second preset threshold.

[0105] In some examples, the conductive trace is a first conductive trace, and a first electrical signal is sent to the first conductive trace via a first end and a second electrical signal is received from the first conductive trace via a second end during a first screen detection cycle.

[0106] In this example, method 1000 may further include: during a second screen detection cycle, sending a third electrical signal to the second conductive trace via a third end of the second conductive trace disposed on the screen and extending along the edge of the screen and separated from the first conductive trace, and receiving a fourth electrical signal from the second conductive trace via the third end, the third electrical signal being configured to be transmitted along the second conductive trace; and determining whether the screen is damaged based on the fourth electrical signal, wherein the second screen detection cycle occurs after the first screen detection cycle. Thus, by setting the first and second conductive traces, dual verification of screen damage detection can be achieved, thereby improving the accuracy of screen damage detection.

[0107] Furthermore, in some examples, the propagation direction of the third electrical signal in the second conductive track is the same as the propagation direction of the first electrical signal in the first conductive track. In other examples, the propagation direction of the third electrical signal in the second conductive track is opposite to the propagation direction of the first electrical signal in the first conductive track.

[0108] In some examples, method 1000 may include: determining screen damage in response to either a second electrical signal or a fourth electrical signal indicating screen damage.

[0109] In other examples, method 1000 may include determining screen damage in response to both a second electrical signal and a fourth electrical signal indicating screen damage. Further, in some examples, the aforementioned second screen detection cycle occurs in response to the second electrical signal indicating screen damage.

[0110] In some examples, multiple first-screen detection cycles and multiple second-screen detection cycles occur alternately.

[0111] In some examples, method 1000 may also include sending a notification to a central management system via a host to report screen damage in response to determining that the screen is broken.

[0112] In some examples, the screen is a touch screen, and method 1000 is executed within a screen detection cycle, outside of the touch detection cycle used to detect whether the screen has been touched.

[0113] This disclosure also provides an electronic device that may include: a processor; and a memory storing computer-executable instructions, which, when executed by the processor, cause the processor to perform the method for detecting the screen state of a display device according to any of the foregoing embodiments. Such an electronic device may include or be used as part of the aforementioned control module.

The computer system 800 includes a bus 802 or other communication mechanism for transmitting information, and a processing means 804 coupled to the bus 802 for processing information. The computer system 800 also includes a memory 806 coupled to the bus 802 for storing instructions to be executed by the processing means 804; the memory 806 may be random access memory (RAM) or other dynamic storage device. The memory 806 may also be used to store temporary variables or other intermediate information during the execution of instructions to be executed by the processing means 804. The computer system 800 also includes a read-only memory (ROM) 808 or other static storage device coupled to the bus 802 for storing static information and instructions for the processing means 804. A storage device 810, such as a magnetic disk or optical disk, is provided and coupled to the bus 802 for storing information and instructions. Computer system 800 may be coupled via bus 802 to output device 812 for providing output to a user, such as, but not limited to, a display (such as a cathode ray tube (CRT) or liquid crystal display (LCD)), speakers, etc. Input device 814, such as a keyboard, mouse, microphone, etc., is coupled to bus 802 for transmitting information and command selections to processing device 804. Computer system 800 may execute embodiments of this disclosure. Consistent with certain implementations of this disclosure, results are provided by computer system 800 in response to processing device 804 executing one or more sequences of one or more instructions contained in memory 806. Such instructions may be read into memory 806 from another computer-readable medium, such as storage device 810. Execution of the sequence of instructions contained in memory 806 causes processing device 804 to perform the methods described herein. Alternatively, the teachings may be implemented using hardwired circuitry in place of or in combination with software instructions. Therefore, implementations of this disclosure are not limited to any particular combination of hardware circuitry and software. In various embodiments, computer system 800 can be connected across a network to one or more other computer systems, such as computer system 800, to form a networked system via network interface 816. This network may include a private network or a public network such as the Internet. In a networked system, one or more computer systems can store data and supply data to other computer systems. As used herein, the term "computer-readable medium" refers to any medium that participates in providing instructions to processing device 804 for execution.

Various forms of computer-readable media may be involved when carrying one or more sequences of one or more instructions to processing device 804 for execution. For example, instructions may initially be carried on a disk of a remote computer. The remote computer may load the instructions into its dynamic memory and transmit the instructions over a telephone line using a modem. A modem local to computer system 800 may receive data over a telephone line and convert the data into an infrared signal using an infrared transmitter.

[0166] One or more hosts, each host communicatively coupled to a corresponding display device among the one or more display devices, and configured to receive a notification from the corresponding display device indicating screen damage and to send the notification to a central management system communicatively coupled to the one or more hosts; and

[0167] The central management system is configured to receive the notification from one or more of the hosts and report the screen damage to the user.

[0168] The terms “left,” “right,” “front,” “back,” “top,” “bottom,” “upper,” “lower,” “high,” “lower,” etc., used in the specification and claims, if present, are for descriptive purposes and not necessarily for describing unchanging relative positions. It should be understood that such terms are interchangeable where appropriate, enabling embodiments of this disclosure described herein to operate, for example, in orientations different from those shown or otherwise described herein. For example, when the device in the drawings is reversed, a feature previously described as “above” other features may now be described as “below” other features. The device may also be oriented in other ways (rotated 90 degrees or in other orientations), in which case the relative spatial relationships will be interpreted accordingly.

[0169] In the specification and claims, when an element is described as being "on top of," "attached to," "connected to," "coupled to," or "in contact with" another element, the element may be directly located on top of, directly attached to, directly connected to, directly coupled to, or directly in contact with the other element, or one or more intermediate elements may be present. Conversely, when an element is described as being "directly" located on top of, directly attached to, directly connected to, directly coupled to, or directly in contact with another element, no intermediate elements are present. In the specification and claims, when a feature is arranged "adjacent" to another feature, it may mean that a feature has a portion overlapping with the adjacent feature or a portion located above or below the adjacent feature.

[0170] As used herein, the term “exemplary” means “serving as an example, instance, or illustration” and not as a “model” to be precisely copied. Any implementation described herein by example is not necessarily to be construed as preferred or advantageous over other implementations. Moreover, this disclosure is not limited to any theory expressed or implied as given in the art, background, utility model, or detailed description.

[0171] As used herein, the term "substantially" means any minor variation resulting from design or manufacturing defects, device or component tolerances, environmental influences, and / or other factors. The term "substantially" also allows for differences from the perfect or ideal situation due to parasitic effects, noise, and other practical considerations that may exist in the actual implementation.

[0172] Furthermore, terms such as “first,” “second,” etc., may be used in this document for reference purposes only and are not intended to be limiting. For example, unless the context clearly indicates otherwise, the words “first,” “second,” and other such numerical terms relating to structures or elements do not imply order or sequence.

[0173] It should also be understood that when the term “including / contains” is used herein, it indicates the presence of the indicated feature, whole, step, operation, unit and / or component, but does not preclude the presence or addition of one or more other features, wholes, steps, operations, units and / or components and / or combinations thereof.

[0174] In this disclosure, the term “provide” is used broadly to cover all ways of obtaining an object, and therefore “provide an object” includes, but is not limited to, “purchasing,” “preparing / manufacturing,” “arranging / setting up,” “installing / assembling,” and / or “ordering” an object.

[0175] As used herein, the term “and / or” includes any and all combinations of one or more of the listed items in association. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. As used herein, the singular forms “a,” “an,” and “the” are also intended to include the plural forms unless the context clearly indicates otherwise.

[0176] Those skilled in the art will recognize that the boundaries between the above operations are merely illustrative. Multiple operations may be combined into a single operation, a single operation may be distributed among additional operations, and operations may be performed with at least partial overlap in time. Moreover, alternative embodiments may include multiple instances of a particular operation, and the order of operations may be changed in various other embodiments. However, other modifications, variations, and substitutions are equally possible. Aspects and elements of all the embodiments disclosed above may be combined in any way and / or in combination with aspects or elements of other embodiments to provide multiple additional embodiments. Therefore, this specification and the accompanying drawings should be considered illustrative rather than restrictive.

[0177] The same or similar parts between the various embodiments of this disclosure can be referred to mutually, and each embodiment focuses on describing the differences from other embodiments. In the description of this disclosure, the reference to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., means that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this disclosure. In this disclosure, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. Furthermore, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this disclosure and the features of the different embodiments or examples.

[0178] Additionally, when used in this disclosure, the terms “here,” “above,” “below,” “below,” “in the following,” “overall,” and similar terms should refer to the entirety of this disclosure and not any particular part thereof. Furthermore, unless expressly stated otherwise or otherwise understood in the context in which they are used, conditional language used herein, such as “may,” “possibly,” “for example,” “like,” etc., is generally intended to express that certain embodiments include, while other embodiments do not, certain features, elements, and / or states. Therefore, such conditional language is not generally intended to imply that one or more embodiments require features, elements, and / or states in any way, or whether such features, elements, and / or states are included or performed in any particular embodiment.

[0179] While specific embodiments of this disclosure have been described in detail by way of example, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of this disclosure. The various embodiments disclosed herein can be combined in any way without departing from the spirit and scope of this disclosure. Those skilled in the art should also understand that various modifications can be made to the embodiments without departing from the scope and spirit of this disclosure. The scope of this disclosure is defined by the appended claims.
