Description

Technical Field

[0001] This invention relates to a display device and related production and heavy industry equipment, and particularly to a splicing display device, an automatic splicing equipment, and a portable screen changing equipment. Background Technology

[0002] Most current splicing display devices use double-sided adhesive to attach all display panels to a mounting plate, a fully laminated manufacturing process. When some display panels malfunction, it's not possible to rework only the malfunctioning panel. Furthermore, the surface flatness of these spliced ​​display panels often depends on the flatness of the bonding surface on the mounting plate. If the flatness of a large-size mounting plate is poor, it can cause noticeable differences between the multiple display panels in the splicing device, affecting the overall appearance. Summary of the Invention

[0003] This invention provides a splicing display device with better reworkability.

[0004] This invention provides an automatic splicing device with better splicing efficiency and accuracy.

[0005] This invention provides a portable panel replacement device that enables high-precision replacement of display panels at the installation site of a splicing display device.

[0006] The splicing display device of the present invention includes a frame, a plurality of display panels, and a plurality of connectors. The frame has a plurality of openings. The plurality of display panels are respectively disposed on the frame corresponding to these openings. The plurality of connectors are detachably fixed to the frame, and each connector has an adhesive layer within its opening. Each connector connects to one of the display panels via the adhesive layer.

[0007] The automatic splicing device of the present invention is suitable for splicing the aforementioned splicing display device, and includes a clamping mechanism, a first moving mechanism, a second moving mechanism, a plurality of image capturing elements, an alignment mechanism, a stage, and a dispensing device. The clamping mechanism is adapted to clamp a frame member. The first and second moving mechanisms are adapted to move on opposite sides of the frame member, respectively. A plurality of image capturing elements are disposed on the first moving mechanism. The alignment mechanism is disposed on the second moving mechanism. The stage is disposed on the alignment mechanism and is adapted to support at least one display panel. The frame member has a receiving surface facing the stage. The alignment mechanism is adapted to move the stage along at least one direction parallel to the receiving surface. The dispensing device is movably disposed on the first moving mechanism and is adapted to inject adhesive layers into the holes of each connector.

[0008] The portable panel-changing device of the present invention is suitable for mounting on the aforementioned splicing display device and includes a base, an alignment mechanism, a stage, and multiple image capturing elements. The base is adapted to be detachably fixed to the frame of the splicing display device. The alignment mechanism is disposed on the base. The stage is disposed on the alignment mechanism and is adapted to support the display panel for repair. Multiple image capturing elements are disposed on the base.

[0009] Based on the above, in a splicing display device according to an embodiment of the present invention, the display panel for splicing is fixed to the frame via multiple connectors. When a portion of the display panel of the splicing display device malfunctions and cannot be repaired, the malfunctioning display panel can be removed by disconnecting the connectors from the frame. This significantly improves the reworkability of the splicing display device. Furthermore, the display panel and connectors are connected by adhesive dispensing, thus increasing the production efficiency and rework convenience of the splicing display device. Based on the above structural features, the present invention also provides an automatic splicing device capable of quickly and accurately producing the aforementioned splicing display device. To enable on-site replacement of the display panel at the installation site of the splicing display device, the present invention further provides a portable panel replacement device. Since the portable panel replacement device can be mounted on the frame of the splicing display device and is equipped with an alignment mechanism and an image capturing element, the splicing accuracy of the repaired display panel can be significantly improved.

[0057] As used herein, “about,” “approximately,” “essentially,” or “substantially” includes the value and the average value within an acceptable range of deviations from a particular value as determined by one of ordinary skill in the art, taking into account the measurement in question and a particular number of errors associated with the measurement (i.e., limitations of the measurement system). For example, “about” may mean within one or more standard deviations of the value, or, for example, within ±30%, ±20%, ±15%, ±10%, ±5%. Furthermore, the use of “about,” “approximately,” “essentially,” or “substantially” herein may be chosen to select a more acceptable range of deviations or standard deviations depending on the nature of the measurement, the cutting nature, or other properties, and a single standard deviation may not be applicable to all properties.

[0058] In the accompanying drawings, the thicknesses of layers, films, panels, regions, etc., are enlarged for clarity. It should be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected to" another element, it may be directly on or connected to the other element, or intermediate elements may also be present. Conversely, when an element is referred to as being "directly on" or "directly connected to" another element, no intermediate elements are present. As used herein, "connection" can refer to a physical and / or electrical connection. Furthermore, an "electrical connection" may involve the presence of other elements between two elements.

[0059] Furthermore, relative terms such as "below" or "bottom" and "above" or "top" may be used herein to describe the relationship between one element and another, as illustrated in the figures. It should be understood that relative terms are intended to include different orientations of the device beyond those shown in the figures. For example, if a device in one figure is flipped, an element described as being "below" to another element will be oriented "above" to that element. Thus, the exemplary term "below" can include both "below" and "above" orientations, depending on the specific orientation of the figure. Similarly, if a device in one figure is flipped, an element described as being "below" or "under" another element will be oriented "above" to that element. Thus, the exemplary terms "above" or "below" can include both "above" and "below" orientations.

[0060] This document describes exemplary embodiments with reference to cross-sectional views as schematic diagrams of idealized embodiments. Therefore, variations in the shape of the illustrations can be expected as a result of, for example, manufacturing techniques and / or tolerances. Consequently, the embodiments described herein should not be construed as limited to the specific shapes of the regions shown herein, but rather include, for example, shape deviations caused by manufacturing processes. For example, regions shown or described as flat may generally have rough and / or non-linear characteristics. Furthermore, the acute angles shown may be rounded. Therefore, the regions shown in the figures are schematic in nature, and their shapes are not intended to show the precise shapes of the regions, nor are they intended to limit the scope of the claims.

[0061] The exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Wherever possible, the same element references are used in the drawings and description to denote the same or similar parts.

For clarity, Figure 3A and Figure 3B Omitted Figure 2 The drawing shows the adhesive layer 190 in the middle.

[0063] Please refer to Figures 1 to 4A The splicing display device 10 includes a frame 100 and a plurality of display panels 200. The frame 100 has a plurality of openings 100OP. The display panels 200 are respectively disposed on the frame 100, corresponding to the openings 100OP, and the openings 100OP expose a plurality of flexible circuit boards 250 on the back side of the display panels 200. The flexible circuit boards 250 are, for example, flip-chip on film (COF), but are not limited thereto.

[0064] In this embodiment, the splicing display device 10 is, for example, a 2x2 array composed of four display panels 200 spliced ​​together, but it is not limited thereto. The number of display panels 200 spliced ​​together in the splicing display device can be adjusted according to different product designs.

[0065] The video wall display device 10 also includes a plurality of connectors 150 detachably fixed to the frame 100. For example, the video wall display device 10 may also include a plurality of locking attachments 170. These locking attachments 170 pass through the frame 100 and are respectively locked to the plurality of connectors 150, thus fixing the connectors 150 to the frame 100. In this embodiment, the locking attachment 170 is, for example, a screw with a threaded end, and the connector 150 has a threaded hole (e.g., a screw) that mates with the threaded end of the locking attachment 170. Figure 3B (as shown), but not limited to this.

[0066] In this embodiment, the connector 150 protrudes from the frame 100 and is exposed within the opening 100OP of the frame 100. Notably, the connector 150 has a hole 150h exposed within the opening 100OP of the frame 100, and this hole 150h overlaps a portion of the surface of a corresponding display panel 200. An adhesive layer 190 is provided within the hole 150h, and the connector 150 is connected to the overlapping display panel 200 (e.g., [other components]) via the adhesive layer 190. Figure 4A (As shown). In other words, the display panel 200 is fixed to the frame 100 by an adhesive relationship with the connector 150.

[0067] Please refer to Figure 4BWhen a portion of the display panel 200 of the video wall display device 10 (e.g., a faulty display panel 200X) malfunctions and cannot be repaired, the faulty display panel 200X can be removed by disconnecting the connector 150 attached to the frame 100. For example, the locking accessory 170 can be removed to release the locking relationship between the connector 150 and the frame 100, thereby removing the faulty display panel 200X. This significantly improves the reworkability of the video wall display device 10, thereby reducing maintenance costs.

[0068] Figure 5A yes Figure 3A A perspective view of another modified embodiment of the splicing display device. Figure 5B yes Figure 5A A cross-sectional view of the splicing display device. Please refer to... Figure 5A and Figure 5B ,exist Figure 3A In a modified embodiment, a height adjustment member 160 may optionally be provided between the locking attachment 170A and the frame member 100A. More specifically, the height adjustment member 160 passes through the frame member 100A, and the locking attachment 170A passes through the height adjustment member 160 and is locked onto the connecting member 150. Figure 5B In one embodiment, the height adjustment member 160 is, for example, a height adjustment screw and has a threaded portion, while the frame member 100A has a screw hole that mates with the threaded portion of the height adjustment screw, but is not limited thereto.

[0069] It is worth mentioning that the height adjustment component 160 can be used to adjust the height of the corresponding display panel 200 on the frame 100A, so as to reduce the height difference (i.e., step difference) between it and the adjacent display panel 200, which helps to improve the overall surface flatness of the splicing display device.

[0070] Figures 6A to 6D This is a cross-sectional schematic diagram illustrating the splicing and manufacturing process of a display panel using an automatic splicing device according to an embodiment of the present invention. Figure 7A and Figure 7B yes Figure 6B A bottom-view diagram showing the alignment mechanism controlling the movement and rotation of the platform.

[0071] Please refer to Figure 6A The automatic splicing equipment 300 is suitable for splicing the aforementioned Figure 1 The splicing display device 10 includes a clamping mechanism 305, a first moving mechanism 310, a second moving mechanism 320, multiple image capturing elements 330, a dispensing device 340, an alignment mechanism 370, and a stage 380. The clamping mechanism 305 is adapted to clamp... Figure 4AThe frame 100 is shown in the diagram. For example, although not shown, the clamping mechanism 305 may be fixed to the base platform 301 of the automated splicing equipment 300, but is not limited thereto. In another embodiment, the clamping mechanism 305 may be disposed on a moving mechanism (not shown) and movable relative to the base platform 301 to realize the feeding and unloading of the frame 100.

[0072] Multiple image capturing elements 330 and a dispensing device 340 are disposed in the first moving mechanism 310. An alignment mechanism 370 and a stage 380 are disposed in the second moving mechanism 320. The first moving mechanism 310 and the second moving mechanism 320 are adapted to move on opposite sides of the frame 100, respectively.

[0073] For example, the frame 100 has a receiving surface 100bs on the side facing the stage 380, and on the side of the receiving surface 100bs, the frame 100 is provided with a plurality of connectors 150. A first moving mechanism 310 is adapted to move a plurality of image capturing elements 330 and dispensing devices 340 above the frame 100 along a first direction D1 and a second direction D2 parallel to the receiving surface 100bs of the frame 100. A second moving mechanism 320 is adapted to move an alignment mechanism 370 and the stage 380 below the frame 100 along the first direction D1 and the second direction D2 parallel to the receiving surface 100bs of the frame 100 and a third direction D3 perpendicular to the receiving surface 100bs. In this embodiment, the first direction D1, the second direction D2, and the third direction D3 may be selectively perpendicular to each other, but are not limited thereto.

[0074] Alignment mechanism 370 is disposed on second moving mechanism 320. Stage 380 is disposed on alignment mechanism 370 and adapted to support display panel 200. In this embodiment, the stage 380 supports one display panel 200 as an example for illustrative purposes and does not represent a limitation of the invention. In other embodiments, the stage may support multiple display panels 200.

[0075] The alignment mechanism 370 is adapted to move the stage 380 along at least one direction parallel to the receiving surface 100bs of the frame 100. For example, in this embodiment, the alignment mechanism 370 is adapted to move the stage 380 along a first direction D1 and a second direction D2, and rotate about a pivot RX perpendicular to the receiving surface 100bs.

[0076] like Figure 7AAs shown in detail, the alignment mechanism 370 may include two first slide rail mechanisms 371a and 371b and two second slide rail mechanisms 372a and 372b, wherein each slide rail mechanism may be a combination of a slider and a slide rail, and the slider is adapted to slide along a specific direction in the slide rail, but is not limited thereto. For example, in this embodiment, the two second slide rail mechanisms 372a and 372b may be disposed on the sliders of the two first slide rail mechanisms 371a and 371b, and move along a first direction D1 or its reverse direction under the drive of the first slide rail mechanisms. The stage 380 is disposed on the sliders of the two second slide rail mechanisms 372a and 372b, and moves along a second direction D2 or its reverse direction under the drive of the second slide rail mechanisms.

[0077] It is particularly noteworthy that, in this embodiment, the actuation of the second slide rail mechanism 372a and the second slide rail mechanism 372b of the alignment mechanism 370 can also operate synchronously and in reverse. For example, as Figure 7B As shown, the slider of the second slide rail mechanism 372b moves along the second direction D2, while the slider of the other second slide rail mechanism 372a moves along the opposite direction of the second direction D2 (i.e., direction D2”). In this way, the stage 380 can be driven to rotate clockwise about the axis RX, and conversely, the stage 380 can be driven to rotate counterclockwise about the axis RX (not shown).

[0078] The following will provide an illustrative explanation of the splicing process of the display panel 200 on the frame 100.

[0079] Please refer to Figure 6A and Figure 6B The second moving mechanism 320 moves along the first direction D1 to below the clamping mechanism 305. When the display panel 200 on the stage 380 overlaps with one of the openings 100OP of the frame 100, the second moving mechanism 320 further drives the stage 380 to rise along the third direction D3, so that the display panel 200 is as close as possible to the connector 150 on the frame 100 but does not contact it.

[0080] Next, the multiple image capturing elements 330 on the first moving mechanism 310 capture images of multiple alignment marks (not shown) on the display panel 200 and confirm the offset between the current position and the ideal position of the display panel 200. If there is an offset, the alignment mechanism 370 can move the stage 380 along the first direction D1 and / or the second direction D2, or even rotate the stage 380 along the pivot RX, so that the display panel 200 on the stage 380 moves to the ideal position.

[0081] After alignment, move the dispensing device 340 above the connector 150 that overlaps with the display panel 200, as shown. Figure 6CAs shown. After the dispensing device 340 reaches its positioning position, it descends to a position close to the connector 150 and injects adhesive material 190M into the hole 150h of the connector 150. It is particularly important to note that this adhesive material 190M will contact the portion of the display panel 200 located within the hole 150h and the sidewalls of the connector 150 defining the hole 150h, and cure to form an integral adhesive layer 190, as shown. Figure 6D As shown.

[0082] In this embodiment, the automatic splicing device 300 may further include a curing element 350, movably disposed on the first moving mechanism 310, and adapted to cure the adhesive layer 190. For example, during the injection of the adhesive material 190M (e.g. Figure 6C After the steps shown are completed, the curing element 350 is moved to a position above the connector 150 in which the adhesive material 190M is injected into the hole 150h. Once the curing element 350 reaches its position, it descends to a position close to the connector 150 and irradiates the adhesive material 190M in the hole 150h with ultraviolet light, causing the adhesive material 190M to cure into an adhesive layer 190. That is, the curing element 350 in this embodiment can be an ultraviolet light source, but is not limited to this.

[0083] The connection relationships between other connectors 150 and the display panel 200 can be repeated. Figure 6C and Figure 6D The steps shown are used to achieve this, and will not be repeated here. After completing the connection between the display panel 200 and all the corresponding connectors 150, the splicing step of one display panel 200 on the frame 100 is completed. Repeat Figures 6A to 6D By following these steps, multiple display panels 200 can be spliced ​​and fixed on the frame 100, thus completing the process. Figure 2 10. Splicing display device.

[0084] It is worth mentioning that since the display panel 200 and the connector 150 are connected by dispensing, the production efficiency and rework convenience of the splicing display device 10 can be increased.

[0085] Figure 8 A portable wafer changing device according to an embodiment of the present invention is mounted on... Figure 2 A schematic diagram on a splicing display device. Figures 9A to 9C It is to utilize Figure 8 A cross-sectional schematic diagram of the splicing process for repairing display panels using a portable panel replacement device.

[0086] Figure 8 and Figure 9A This illustrates a portable panel changing device 400 that can be mounted on a video wall display device 10. When a portion of the display panel in the video wall display device 10 (such as...) is being changed... Figure 4BWhen the abnormal display panel 200X malfunctions and cannot be repaired, maintenance personnel can directly replace the abnormal display panel at the installation site of the splicing display device 10 using the portable panel replacement equipment 400.

[0087] Please refer to Figure 8 and Figure 9A Specifically, the portable panel changing device 400 includes a base 401, an alignment mechanism 470, a stage 480, and multiple image capturing elements 430. The base 401 is detachably fixed to the frame 100 of the splicing display device 10. The alignment mechanism 470 and the multiple image capturing elements 430 are disposed on the base 401. The stage 480 is disposed on the alignment mechanism 470, and its receiving surface 480bs opposite to the alignment mechanism 470 is adapted to support the repair display panel 200R.

[0088] It is worth noting that the portable wafer changer 400 also includes multiple support columns 410 that connect to the base 401. When the portable wafer changer 400 is mounted on the frame 100, these support columns 410 will create a space SP between the base 401 and the frame 100, and an alignment mechanism 470 is provided in this space SP.

[0089] The portable wafer changer 400 can be locked onto the frame 100 by multiple locking accessories 405. For example, the base 401 has a hole 401h in the part connecting the support column 410, and the locking accessories 405 (such as fixing screws) can pass through the hole 401h of the base 401 and the support column 410 and be locked onto the frame 100, so that the portable wafer changer 400 is fixed to the frame 100.

[0090] The alignment mechanism 470 is adapted to move the stage 480 along a first direction D1 and a second direction D2 parallel to the receiving surface 480bs, and to rotate about a pivot RX perpendicular to the receiving surface 480bs. Since the alignment mechanism 470 of the portable piece changing device 400 is similar to the alignment mechanism 370 of the aforementioned automatic splicing device 300, please refer to the relevant paragraphs above for a detailed description, and it will not be repeated here.

[0091] The following is a demonstrative explanation of the wafer changing process for the portable wafer changer 400. First, as... Figure 4B As shown, the faulty display panel 200X is removed by first disconnecting the connector 150 from the frame 100. For example, the locking accessory 170 can be removed to disconnect the connector 150 from the frame 100, thereby removing the faulty display panel 200X.

[0092] It is particularly important to note that after removing the malfunctioning display panel 200X, the connector 150 on the frame 100 that was originally connected to the malfunctioning display panel 200X will also be removed (e.g., Figure 4B (As shown). Therefore, before the replacement procedure begins, multiple connectors 150 need to be reattached to the frame 100 for connection of the subsequent replacement display panel.

[0093] After removing the faulty display panel 200X, the portable panel changing device 400 is mounted and secured to the side of the frame 100 opposite to the display panel 200. For example... Figure 9A As shown, the portable plate changing device 400 mounted on the frame 100 has a platform 480 adapted to pass through the opening 100OP of the frame 100 and protrude to the side of the frame 100 away from the base 401 to receive the repair display panel 200R.

[0094] It is particularly important to note that the protrusion of the stage 480 from the opening 100OP should be such that a small gap is maintained between the repair display panel 200R and the connector 150 on the frame 100, in order to facilitate subsequent alignment operations.

[0095] After the portable film changing device 400 completes film retrieval, multiple image capturing elements 430 are used to capture images of multiple alignment marks (not shown) on the repair display panel 200R and confirm the offset between the current position and the ideal position of the repair display panel 200R. If there is an offset, the alignment mechanism 470 can move the stage 480 along the first direction D1 and / or the second direction D2, or even rotate the stage 480 along the pivot RX, so that the repair display panel 200R on the stage 480 moves to the ideal position.

[0096] After alignment, an adhesive material 190M is injected into the holes 150h of the corresponding connectors 150 using a (handheld) dispensing applicator 440, and cured to form an adhesive layer 190 between the display panel 200R for connection and repair and the connectors 150. The curing method of the adhesive material 190M can be the same as... Figure 6D The present invention does not limit the use of similar light-curing (e.g., ultraviolet light or laser), moisture-curing, or other curing methods suitable for on-site application. Therefore, the selection of the adhesive 190M can be adjusted to accommodate different curing methods.

[0097] Please refer to Figure 9C After completing the connection between the repair display panel 200R and the frame 100, the locking accessory 405 can be removed to release the locking relationship between the portable panel replacement device 400 and the frame 100. This completes the panel replacement process for the splicing display device 10.

[0098] Since the portable panel changing device 400 can be mounted on the frame 100 of the splicing display device 10 and is equipped with an alignment mechanism 470 and an image capturing element 430, the splicing accuracy of the repair display panel 200R on the frame 100 can be significantly improved.

[0099] In summary, in one embodiment of the splicing display device of the present invention, the display panel for splicing is fixed to the frame via multiple connectors. When a portion of the display panel of the splicing display device malfunctions and cannot be repaired, the malfunctioning display panel can be removed by disconnecting the connectors from the frame. This significantly improves the reworkability of the splicing display device. Furthermore, the display panel and connectors are connected by adhesive dispensing, thus increasing the production efficiency and rework convenience of the splicing display device. Based on the above structural features, the present invention also provides an automatic splicing device capable of quickly and accurately producing the aforementioned splicing display device. To enable on-site replacement of the display panel at the installation site of the splicing display device, the present invention also provides a portable panel replacement device. Since the portable panel replacement device can be mounted on the frame of the splicing display device and is equipped with an alignment mechanism and an image capturing element, the splicing accuracy of the repaired display panel can be significantly improved.
