[0038] Various exemplary embodiments, features, and aspects of this disclosure will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0039] In the description of this disclosure, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this disclosure and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure.

[0040] 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this disclosure, "a plurality of" means two or more, unless otherwise expressly specified.

[0041] In this disclosure, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0042] In this document, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Furthermore, the term "at least one" in this document means any combination of at least two of any one or more elements. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C.

[0043] Figure 1 A schematic diagram of the structure of a display panel fragment detection device according to an embodiment of the present disclosure is provided.

[0044] like Figure 1As shown, 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 disposed on opposite side edges of the display panel; the at least one photosensitive element is used to receive light signals emitted by the at least one light source and detect the intensity of each light signal; the computing unit is used to compare the intensity of each light signal with a preset signal intensity threshold, determine a first light signal with an intensity lower than the preset signal intensity threshold; and determine the fragment position according to the optical path corresponding to each first light signal.

[0045] exist Figure 1 In this design, a circular icon on one side of the panel represents the light source in the device, and a square icon on the other side represents the photosensitive element. A computing unit is also included within the panel. The computing unit can be positioned anywhere within the panel or outside the panel; this embodiment does not limit the placement of the computing unit. The photosensitive element can be wired or wirelessly connected to the computing unit, at least transmitting the intensity of the light signal detected by the photosensitive element to the computing unit.

[0046] In this embodiment of the disclosure, the light source and the photosensitive element can be disposed on the left and right sides of the panel (e.g., Figure 1 (As shown). Alternatively, it can be set on the top and bottom sides of the panel (as shown). Figure 1 (Not shown in the image). Furthermore, the light source in this embodiment can be a light source integrated into the panel, or a light source other than the panel's built-in light source. The light source can be a constant current power supply, an AC power supply, a pulse width modulation (PWM) power supply, etc. The number of light sources and photosensitive elements can be the same or different.

[0047] The panel in this embodiment can be a single liquid crystal panel or a wall of liquid crystal panels arranged in a plurality of liquid crystal panels.

[0048] Light emitted from a light source can be refracted by a panel to produce refracted light. The light signal in this embodiment can be an electrical signal converted from the refracted light. The device in this embodiment may further include a reflector (…). Figure 1 (Not shown in the image). A reflector can reflect light emitted from a light source onto one or more preset photosensitive elements. The light signal can be an electrical signal converted from the reflected light.

[0049] In this embodiment of the disclosure, there may be multiple preset signal strength thresholds. For the light signal of a single light source, each photosensitive element may correspond to a preset signal strength threshold.

[0050] For example, the device may include two light sources, namely light source A and light source B; it may also include two photosensitive elements, namely photosensitive element A and photosensitive element B. Both photosensitive element A and photosensitive element B can receive light emitted by light source A and light source B, respectively. Photosensitive element A can receive the light signal AA emitted by light source A and determine the intensity of light signal AA. The calculation unit can compare light signal AA with a first preset signal intensity threshold. Photosensitive element A can receive the light signal AB emitted by light source B and determine the intensity of light signal AB. The calculation unit can compare light signal AB with a second preset signal intensity threshold. Photosensitive element B receives the light signal BA emitted by light source A and determines the intensity of light signal BA. The calculation unit can compare light signal BA with a third preset signal intensity threshold. Photosensitive element B receives the light signal BB emitted by light source B and determines the intensity of light signal BB. The calculation unit can compare light signal BB with a fourth preset signal intensity threshold.

[0051] Therefore, when a single optical signal is less than the corresponding preset signal strength, that optical signal is identified as the first optical signal. The fragment location can be a position on the optical path corresponding to the first signal, or a preset range encompassing the optical path corresponding to the first signal can be used as the fragment location.

[0052] The device in this embodiment includes at least one light source, at least one photosensitive element, and a computing unit. The light source and the photosensitive element are disposed on opposite sides of a display panel. The at least one photosensitive element receives light signals emitted by the at least one light source and detects the intensity of each light signal. The computing unit compares each received light signal with a preset signal intensity threshold to determine a first light signal with an intensity lower than the preset signal intensity threshold. Based on the optical path corresponding to each first light signal, the location of the fragment is determined. This allows for the detection of whether a fragment exists at or within the edge of the panel, and the location of the fragment. This enables timely replacement or repair of the panel, reducing the probability of affecting image display. Furthermore, this device only requires the light source and photosensitive element to be disposed on opposite sides of the panel, saving space and freeing up space for other components, thus reducing the overall size of the device including the panel and lowering costs.

[0053] In one possible implementation, the computing unit includes: a fragment region determination unit, configured to determine a fragment region 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, configured to determine the fragment region as the fragment position.

[0054] In this embodiment of the disclosure, the location of the fragment can be represented as the location corresponding to a region.

[0055] In one example, the fragmentation region can be rectangular. The calculation unit can use the length of the optical path corresponding to the first optical signal as the length of the long side of the fragmentation region, and a preset length as the length of the short side. The region enclosed by the optical path corresponding to the first optical signal as the central axis, and the two long sides and two short sides, can be defined as the fragmentation region; the position of the fragmentation region can be defined as the fragment position.

[0056] In another example, the fragmentation region can be elliptical. The computing unit can use the optical path corresponding to the first optical signal as the major axis, and determine the minor axis perpendicular to the major axis and passing through the midpoint of the major axis. The length of the minor axis can be a preset length. The elliptical region defined by the major and minor axes can be defined as the fragmentation region; the position of the fragmentation region is used as the fragment position.

[0057] In this embodiment, the calculation unit can determine the fragment region based on the preset length and the optical path corresponding to each first optical signal, and then determine the fragment region as the fragment location. This not only checks whether there are fragments in the panel, but also identifies the fragment region, narrowing the search range for further investigation of the fragment's coordinates and improving the efficiency and accuracy of determining the fragment's coordinates.

[0058] In one possible implementation, the computing unit includes a second fragment positioning unit, used to determine the intersection of the optical paths corresponding to the two first optical signals as the fragment position.

[0059] The location of the fragment can be represented by a point coordinate. In this embodiment, when there are two first optical signals and the optical paths corresponding to these two first optical signals intersect, the calculation unit can determine the coordinates of the intersection point of the optical paths corresponding to these two first signals as the fragment location. In this way, the fragment location can be directly located, improving the efficiency of determining the fragment location.

[0060] In one possible implementation, 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 at least one photosensitive element is turned on simultaneously. Each light source corresponds to a first coordinate, and each photosensitive element corresponds to a second coordinate. The device further includes: a coordinate acquisition unit, used to acquire the first coordinate of the light source corresponding to a single first light signal and the second coordinate of the corresponding photosensitive element; and a first optical path determination unit, used to determine the optical path corresponding to the single first light signal based on the first coordinate and the second coordinate.

[0061] by Figure 1For example, the activation sequence can be sequentially activated from top to bottom or from bottom to top. Alternatively, it can be based on the probability of fragmentation, activating the light sources corresponding to areas prone to fragmentation first, followed by those corresponding to areas less prone to fragmentation. For instance, the topmost or bottommost light source can be activated alternately first, and then the light sources can be activated alternately from top to bottom and from bottom to top. For example, there are five light sources on the left side of the panel, numbered from top to bottom as light source a, light source b, light source c, light source d, and light source e. If the areas at the top and bottom edges of the panel are most prone to fragmentation, and the middle part of the panel is least prone to fragmentation, then the preset activation sequence can be: light source a - light source e - light source b - light source d - light source c. The light sources in areas prone to fragmentation have stronger light signals in those areas, making the light signal intensity more sensitive to fragmentation, thus improving the accuracy of determining the fragment location. The above are merely examples, and this disclosure does not limit the preset activation sequence.

[0062] In this embodiment, the first coordinates corresponding to each light source and the second coordinates corresponding to each photosensitive element can be pre-stored. Since only one light source is turned on at a time, one end of each optical path determined in a single operation represents the light source turned on at that time, and the other end represents each photosensitive element. With only one light source turned on, the target light source is determined; after determining the first light signal, the target photosensitive element corresponding to the first light signal can be determined. The coordinate acquisition unit can acquire 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 and second coordinates corresponding to the single first light signal, and this straight line can be used to represent the optical path corresponding to the single first signal. This allows for accurate positioning of the optical path corresponding to the first signal on the panel, improving the accuracy of determining the fragment position.

[0063] In one possible implementation, the at least one light source and at least one photosensitive element are simultaneously turned on. Each light source corresponds to a first identifier and a first coordinate, and each photosensitive element corresponds to a second identifier and a second coordinate. The device further includes: a first duration determination unit, used to determine a first duration from the emission to the reception of a single first optical signal, wherein the duration from the emission to the reception of optical signals emitted by each light source is different for each photosensitive element; a first identifier acquisition unit, used to acquire a second identifier of the photosensitive element corresponding to the reception of the single first optical signal; a second identifier determination unit, used to determine a first identifier of the light source corresponding to the single first optical signal based on the second identifier and the first duration; and a second optical path determination unit, used to determine the optical path corresponding to the single first optical signal based on the first coordinate corresponding to the first identifier and the second coordinate corresponding to the second identifier.

[0064] In this embodiment, because the distance between each photosensitive element and each light source is different, the duration for which each photosensitive element receives the light signal emitted by each light source is different when all light sources and photosensitive elements are turned on simultaneously. However, the duration for which a single photosensitive element receives the light signal from a single light source can be fixed. The durations corresponding to the same photosensitive element can be pre-stored, with each duration corresponding to one light source.

[0065] The first duration unit can count the time from when any light source emits a light signal to when that light signal reaches any photosensitive element. When the light source is an AC light source, the number of phases the light signal from any light source experiences before reaching any photosensitive element can be counted. The product of the number of phases and the unit time corresponding to each phase is then used as the duration from emission to reception. When the light source is a PWM power supply, the number of pulses the light signal from any light source experiences before reaching any photosensitive element can be counted. The product of the number of pulses and the unit time corresponding to each pulse is then used as the duration from emission to reception. Therefore, each photosensitive element receives a light signal corresponding to a duration. For ease of description below, the duration corresponding to the first light signal is named the first duration.

[0066] Light signals are emitted from a light source and arrive at the photosensitive element. Therefore, each light signal can correspond to a first identifier and a second identifier. For a single photosensitive element, after receiving a light signal, the first identifier corresponding to the received light signal can be determined.

[0067] For a single photosensitive element, the first identifier and the first duration corresponding to the first optical signal can be obtained.

[0068] In one example, the first duration can be compared with each duration pre-stored for the single photosensitive element, the second duration with the closest value can be selected, the light source corresponding to the second duration can be determined, and the first identifier corresponding to the light source can be determined.

[0069] In another example, the first duration can be compared with each duration pre-stored for the single photosensitive element, a third duration with an error within the threshold range can be selected, the light source corresponding to the third duration can be determined, and the first identifier corresponding to the light source can be determined.

[0070] In this way, for a single photosensitive element, the first identifier corresponding to the first optical signal can be determined.

[0071] In this embodiment, a first identifier and first coordinates can be stored for a single light source, and a second identifier and second coordinates can be stored for a single photosensitive element. A straight line can be constructed using the first and second coordinates corresponding to the first light signal, and this straight line can be used to characterize the optical path corresponding to the first light signal. This allows for accurate positioning of the optical path corresponding to the first signal on the panel, improving the accuracy of determining the fragment's location. Since all light sources and photosensitive elements are activated simultaneously, the detection efficiency of fragments throughout the entire panel can be improved.

[0072] In one possible implementation, the at least one light source and the at least one photosensitive element are alternately arranged on opposite side edges of the panel.

[0073] Figure 2 A schematic diagram of an embodiment of this disclosure is provided, showing an alternating arrangement of a light source and a photosensitive element. (See attached diagram.) Figure 2 As shown, circular icons represent light sources in the device, and square icons represent photosensitive elements. A line connecting a single light source and a single photosensitive element forms an optical path. When the light sources are turned on one by one in a predetermined sequence, the light signal emitted by a single light source covers a large area, and fragments can be detected from both sides, improving the efficiency of determining the presence of fragments and locating them.

[0074] In one possible implementation, the at least one light source is disposed on the same side of the display panel, and the at least one photosensitive element is disposed on the same side of the display panel.

For example... Figure 3 As shown, circular icons represent light sources in the device, and square icons represent photosensitive elements. A line connecting a single light source and a single photosensitive element forms an optical path. In this embodiment, a single light source corresponds to more sensing elements. When both the light source and the photosensitive element are simultaneously activated, the optical path is densely distributed across the panel, improving the accuracy of determining the presence of fragments and locating them.
