[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the present disclosure, "plurality" means two or more, unless otherwise specifically defined.

[0043] In this disclosure, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components or interaction between two components.

[0045] FIG1 provides a schematic structural diagram of a display panel fragment detection device according to an embodiment of the present disclosure.

[0046] As shown in Figure 1, the device includes: at least one light source, at least one photosensitive element and a computing unit, wherein: the light source and the photosensitive element are arranged on opposite side edges of the display panel; the at least one photosensitive element is used to receive the light signal emitted by the at least one light source and detect the intensity of the at least one light signal; the computing unit is used to compare the intensity of the at least one light signal with a preset signal intensity threshold, determine a first light signal whose intensity is lower than the preset signal intensity threshold; and determine the fragment position based on the optical path corresponding to the at least one first light signal.

[0047] In Figure 1, the circular icon on one side of the panel represents the light source in the device, and the square icon on the other side of the panel represents the photosensitive element in the device. The panel also includes a computing unit. The computing unit can also be set anywhere within the panel or outside the panel. The embodiment of the present disclosure does not limit the location of the computing unit. The photosensitive element can be connected to the computing unit by wire or wirelessly, and at least the intensity of the light signal detected by the photosensitive element is transmitted to the computing unit.

[0048] In the embodiment of the present disclosure, the light source and the photosensitive element can be arranged on the left and right sides of the panel (as shown in FIG1 ). Alternatively, they can be arranged on the upper and lower sides of the panel (not shown in FIG1 ). Moreover, the light source in the embodiment of the present disclosure can be a light source provided by the panel, or a light source other than the light source provided by the panel. The light source can be a constant current power supply, an alternating current power supply, a pulse width modulation (PWM) power supply, etc. The number of light sources and photosensitive elements can be the same or different.

[0049] The panel in the embodiment of the present disclosure may be a single liquid crystal panel or a liquid crystal panel wall formed by arranging multiple liquid crystal panels.

[0050] Light emitted by the light source can be refracted by the panel to produce refracted light. The optical signal in the embodiment of the present disclosure can be an electrical signal converted from the refracted light. The device of the embodiment of the present disclosure can also include a reflector (not shown in Figure 1). The reflector can reflect the light emitted by the light source onto one or more preset photosensitive elements. The optical signal can be an electrical signal converted from the reflected light.

[0051] In the embodiment of the present disclosure, there may be multiple preset signal strength thresholds. For a light signal from a single light source, a single photosensitive element may correspond to one preset signal strength threshold.

[0052] For example, the device may include two light sources, namely light source A and light source B; and may also include two photosensitive elements, namely photosensitive element A and photosensitive element B. Then, photosensitive element A and photosensitive element B can both receive light emitted by light sources A and B. Photosensitive element A can receive light signal AA emitted by light source A and determine the intensity of light signal AA. The computing unit can compare light signal AA with a first preset signal intensity threshold. Photosensitive element A can receive light signal AB emitted by light source B and determine the intensity of light signal AB. The computing unit can compare light signal AB with a second preset signal intensity threshold. Photosensitive element B receives light signal BA emitted by light source A and determines the intensity of light signal BA. The computing unit can compare light signal BA with a third preset signal intensity threshold. Photosensitive element B receives light signal BB emitted by light source B and determines the intensity of light signal BB. The computing unit can compare light signal BB with a fourth preset signal intensity threshold.

[0053] Therefore, when a single optical signal is less than the corresponding preset signal strength, the optical signal is determined to be the first optical signal. The fragmentation location can be a certain location on the optical path corresponding to the first signal. Alternatively, a preset range of the optical path corresponding to the first signal can be used as the fragmentation location.

[0054] The device in the disclosed embodiment includes at least one light source, at least one photosensitive element, and a computing unit, wherein: the light source and the photosensitive element are disposed on opposite edges of a display panel; the at least one photosensitive element is configured to receive a light signal emitted by the at least one light source and detect the intensity of the at least one light signal; the computing unit is configured to compare the at least one received light signal with a preset signal intensity threshold to determine a first light signal having an intensity below the preset signal intensity threshold; and the location of a fragment is determined based on the optical path corresponding to the at least one first light signal. This allows detection of the presence of fragments at the edge of the panel and / or within the edge, as well as the location of the fragments, enabling timely replacement or repair of the panel and reducing the likelihood of image display being affected. Furthermore, the device only provides the light source and photosensitive element on opposite sides of the panel, which saves space, freeing up space for other components and reducing the overall size of the device containing the panel, while also reducing costs.

[0055] In one possible implementation, the calculation unit includes: a fragment area determination unit, used to determine the fragment area with the optical path corresponding to a single first optical signal as the central axis according to a preset length; and a first fragment positioning unit, used to determine the fragment area as the fragment position.

[0056] In the embodiment of the present disclosure, the fragment position may be represented as a position corresponding to an area.

[0057] In one example, the fragmentation area may be rectangular. The calculation unit may use the length of the optical path corresponding to the first optical signal as the length of the long side of the fragmentation area. A preset length may be used as the length of the short side of the fragmentation area. The fragmentation area may be defined by the optical path corresponding to the first optical signal as the central axis and the area enclosed by the two long sides and the two short sides. The position of the fragmentation area may be used as the fragmentation position.

[0058] In another example, the fragmentation region may be elliptical. The computing unit may use the optical path corresponding to the first optical signal as the major axis and determine a minor axis perpendicular to the major axis and passing through the midpoint of the major axis. The minor axis may have a predetermined length. An elliptical region defined by the major and minor axes may be determined as the fragmentation region; the position of the fragmentation region may be used as the fragmentation position.

[0059] In the disclosed embodiment, the calculation unit can determine a fragment area based on a preset length and the optical path corresponding to at least one first optical signal, and then identify the fragment area as the fragment location. This not only allows for checking for fragments within the panel but also allows for determining the fragment area. This narrows the scope for further investigation of the coordinates of the fragments, improving the efficiency and accuracy of determining the fragment coordinates.

[0060] In a possible implementation, the calculation unit includes: a second fragment positioning unit, configured to determine an intersection of optical paths corresponding to two first optical signals as the fragment position.

[0061] The fragment location can be represented by a point coordinate. In the disclosed embodiment, when two first light signals exist and the light paths corresponding to these two first light signals intersect, the calculation unit can determine the coordinates of the intersection of the light paths corresponding to these two first signals as the fragment location. This allows the fragment location to be directly located, improving the efficiency of determining the fragment location.

[0062] In one possible implementation, the multiple light sources are turned on one by one in a preset turn-on order. After a single light source is turned off, the next light source is turned on, and the at least one photosensitive element is turned on at the same time. The single light source corresponds to a first coordinate, and the single photosensitive element corresponds to a second coordinate. The device also includes: a coordinate acquisition unit, which is used to acquire the first coordinate of the light source corresponding to the single first light signal and the second coordinate of the corresponding photosensitive element; a first light path determination unit, which is used to determine the light path corresponding to the single first light signal based on the first coordinate and the second coordinate.

[0063] Taking Figure 1 as an example, the order of turning on the light sources can be one by one from top to bottom, or one by one from bottom to top. Alternatively, the light sources corresponding to the areas prone to fragmentation can be turned on first, and then the light sources corresponding to the areas less prone to fragmentation can be turned on, based on the probability of fragmentation. For example, the topmost or bottommost light sources can be turned on alternately first, and then the light sources can be turned on alternately from top to bottom and from bottom to top. For example, there are five light sources on the left side of the panel, from top to bottom, they are light source a, light source b, light source c, light source d, and light source e. If the areas where the upper and lower edges of the panel are more prone to fragmentation, and the middle part of the panel is less prone to fragmentation, then the preset turn-on order can be: light source a - light source e - light source b - light source d - light source c. The light sources in the areas prone to fragmentation have stronger optical signals in that area, so the intensity of the optical signal is more sensitive to fragmentation, thereby improving the accuracy of determining the location of the fragmentation. The above is only an example, and the embodiments of the present disclosure do not limit the preset turn-on order.

[0064] In the embodiment of the present disclosure, the first coordinates corresponding to a single light source and the second coordinates corresponding to a single photosensitive element can be pre-stored. Since only one light source is turned on at a time, one end of the single light path determined at a time is the light source turned on at a time, and the other end is the photosensitive element. In the case of a single light source being turned on, the target light source is determined; after the first light signal is determined, the target photosensitive element corresponding to the first light signal can be determined. The coordinate acquisition unit can obtain the first coordinates of the target light source and the second coordinates of the target photosensitive element. That is, the first coordinates of the light source corresponding to the first light signal and the second coordinates of the corresponding photosensitive element are obtained. For a single first light signal, a straight line can be constructed using the first coordinates and the second coordinates corresponding to the single first light signal, and the straight line can be used to characterize the light path corresponding to the single first signal. In this way, the light path corresponding to the first signal can be accurately positioned on the panel, thereby improving the accuracy of determining the position of the fragments.

[0065] In one possible implementation, the at least one light source and the at least one photosensitive element are turned on at the same time, a single light source corresponds to a first identifier and a first coordinate, and a single photosensitive element corresponds to a second identifier and a second coordinate, and the device also includes: a first duration determination unit, used to determine the first duration from the issuance to the reception of a single first light signal, and for a single photosensitive element, the duration from the issuance to the reception of light signals emitted by different light sources is different; a first identifier acquisition unit, used to acquire the first identifier of the photosensitive element corresponding to the single first light signal; a second identifier determination unit, used to determine the second identifier of the light source corresponding to the single first light signal based on the first identifier and the first duration; a second optical path determination unit, used to determine the optical path corresponding to the single first light signal based on the first coordinate corresponding to the first identifier and the second coordinate corresponding to the second identifier.

[0066] In the disclosed embodiments, because the distances between a single photosensitive element and a single light source vary, when at least one light source and at least one photosensitive element are simultaneously turned on, the duration for which a single photosensitive element receives a light signal from at least one light source may vary. However, the duration for which a single photosensitive element receives a light signal from a single light source may be fixed. At least one duration corresponding to the same photosensitive element may be pre-stored, with each duration corresponding to a single light source.

[0067] The first duration unit can count the time it takes for any light source to emit a light signal and for the light signal to reach any photosensitive element. In the case where the light source is an AC light source, the number of phases that a light signal emitted by any light source goes through to reach any photosensitive element can be counted, and then the product of the number of phases and the unit time corresponding to a single phase can be used as the time it takes for the light signal to be emitted to be received. In the case where the light source is a PWM power supply, the number of pulses that a light signal emitted by any light source goes through to reach any photosensitive element can be counted, and then the product of the number of pulses and the unit time corresponding to a single pulse can be used as the time it takes for the light signal to be emitted to be received. Therefore, the light signal received by a single photosensitive element will correspond to a duration. For the convenience of the following description, the duration corresponding to the first light signal is named the first duration.

[0068] A light signal is emitted from a light source and reaches a photosensitive element. Therefore, a single light signal can correspond to a first identifier and a second identifier. Upon receiving a light signal, a single photosensitive element can determine the first identifier corresponding to the received light signal.

[0069] For a single photosensitive element, a first identifier and a first duration corresponding to the first light signal can be obtained.

[0070] In one example, the first duration can be compared with at least one duration pre-stored for the single photosensitive element, a second duration with the closest value can be selected, the light source corresponding to the second duration can be determined, and a second identifier corresponding to the light source can be determined.

[0071] In another example, the first duration can be compared with at least one duration pre-stored for the single photosensitive element, a third duration with an error within a threshold range can be selected, the light source corresponding to the third duration can be determined, and the second identifier corresponding to the light source can be determined.

[0072] In this way, for a single photosensitive element, the second identifier corresponding to the first light signal can be determined.

[0073] In the disclosed embodiments, a second identifier and first coordinates can be stored for a single light source, and a first identifier and second coordinates can be stored for a single photosensitive element. A straight line can be constructed using the first coordinates and second coordinates corresponding to the first light signal, and this straight line can be used to represent the light path corresponding to the first light signal. This allows the light path corresponding to the first signal to be accurately located on the panel, improving the accuracy of determining the location of fragments. Since at least one light source and at least one photosensitive element are activated simultaneously, the efficiency of detecting fragments across the entire panel can be improved.

[0074] In a possible implementation, the at least one light source and the at least one photosensitive element are alternately arranged on two opposite edges of the panel.

[0075] Figure 2 provides a schematic diagram of the structure of an alternate arrangement of light sources and photosensitive elements in an embodiment of the present disclosure. As shown in Figure 2, circular icons can represent light sources in the device, and square icons can represent photosensitive elements in the device. The line connecting a single light source and a single photosensitive element constitutes an optical path. When at least one light source is turned on one by one in a predetermined order, the optical signal emitted by a single light source covers a larger area and can detect fragments from both sides, improving the efficiency of determining the presence of fragments and locating the fragments.

[0076] In a possible implementation, the at least one light source is disposed on a same side of the display panel, and the at least one photosensitive element is disposed on a same side of the display panel.

[0077] FIG3 provides a schematic diagram of the structure of the light source and photosensitive element of the embodiment of the present disclosure, which are arranged on both sides of the panel. As shown in FIG3, the circular icon can represent the light source in the device, and the square icon can represent the photosensitive element in the device. The line connecting a single light source and a single photosensitive element is a light path. In the embodiment of the present disclosure, a single light source corresponds to more sensing elements. When the light source and the photosensitive element are turned on at the same time, the light path is densely distributed over the panel, which can improve the accuracy of determining whether there are fragments and locating the fragments.

[0078] FIG4 is a flow chart of a display panel fragment detection method according to an embodiment of the present disclosure. As shown in FIG4 , the method includes:
