Description

Splice display device, automatic splice equipment and portable disc changing equipment

Technical Field

The present invention relates to a display device and related production and reworking equipment thereof, and more particularly to a tiled display device, an automatic stitching equipment and a portable film changer.

Background

Most of the existing spliced display devices use double-sided adhesive tape to attach all display panels to a fixed plate, i.e. a full-lamination manufacturing process. When a part of the display panel is abnormally operated, rework cannot be performed only for the abnormally operated display panel. On the other hand, the surface flatness of these display panels after being spliced often depends on the surface flatness of the bonding surface on the fixing plate. If the processing flatness of the large-size fixing plate is poor, obvious step differences are generated among a plurality of display panels of the spliced display device, and the overall appearance is affected.

The invention provides a spliced display device with better reworkability.

The invention provides automatic splicing equipment which has better splicing efficiency and splicing precision.

The invention provides a portable film changer which can perform high-precision display panel replacement in the installation site of a spliced display device.

The invention discloses a spliced display device which comprises a frame piece, a plurality of display panels and a plurality of connecting pieces. The frame member is provided with a plurality of openings. The display panels are respectively arranged on the frame piece corresponding to the openings. The connecting pieces are detachably fixed on the frame piece, and the adhesive layers are arranged in the holes of the connecting pieces. Each connecting piece is connected with one of the display panels through the adhesive layer.

The automatic splicing equipment is suitable for splicing the spliced display device and comprises a clamping mechanism, a first moving mechanism, a second moving mechanism, a plurality of image capturing elements, an alignment mechanism, a carrying platform and a dispenser.

Detailed Description

As used herein, "about," "approximately," "substantially," or "essentially" includes mean values of the values and within acceptable deviation of the particular values as determined by one of ordinary skill in the art, taking into account the particular number of measurements and errors associated with the measurements (i.e., limitations of the measurement system) in question. For example, "about" may mean within one or more standard deviations of the values, or within, for example, ±30%, ±20%, ±15%, ±10%, ±5%. Further, "about," "approximately," "substantially," or "essentially" as used herein may be used to select a range of acceptable deviations or standard deviations depending on the measured, cut, or other property, and may be used for all properties without one standard deviation.

In the drawings, the thickness of layers, films, panels, regions, etc. are exaggerated for clarity. It will 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 can be directly on or connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements present. As used herein, "connected" may refer to physical and/or electrical connections. Furthermore, "electrically connected" may be used in conjunction with other devices that exist between two devices.

Furthermore, relative terms such as "lower" or "bottom" and "upper" or "top" may be used herein to describe one element's relationship to another element as illustrated. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the figures. For example, if the device in one figure is turned over, elements described as being on the "lower" side of other elements would then be oriented on the "upper" side of the other elements. Thus, the exemplary term "lower" may include both "lower" and "upper" orientations, depending on the particular orientation of the figure. Similarly, if the device in one figure is turned over, elements described as "below" or "beneath" other elements would then be oriented "above" the other elements. Thus, the exemplary terms "above" or "below" can encompass both an orientation of above and below.

Exemplary embodiments are described herein with reference to cross-sectional illustrations that are schematic illustrations of idealized embodiments. Thus, shape variations of the illustrations as a result, for example, of manufacturing techniques and/or (and/or) tolerances are to be expected. Thus, the embodiments described herein should not be construed as limited to the particular shapes of regions as illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. For example, an area shown or described as being flat may generally have rough and/or nonlinear features. Furthermore, the acute angles shown may be rounded. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region and are not intended to limit the scope of the claims.

Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.

Fig. 1 is a front view schematically showing a tiled display device according to an embodiment of the present invention. Fig. 2 is a schematic rear view of the tiled display device of fig. 1. Fig. 3A is a partially enlarged perspective view of the tiled display device of fig. 2. Fig. 3B is a partial cross-sectional view of the tiled display device of fig. 2. Fig. 4A is a schematic cross-sectional view of the tiled display device of fig. 1. Fig. 4B is a schematic cross-sectional view of the tiled display device of fig. 1 when the abnormal display panel is removed. For clarity, fig. 3A and 3B omit the adhesive layer 190 of fig. 2.

Referring to fig. 1 to 4A, the tiled 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 disposed on the frame member 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 panel 200. The flexible circuit board 250 is, for example, a Chip On Film (COF), but is not limited thereto.

In the present embodiment, the tiled display device 10 is, for example, a two-by-two array formed by stitching four display panels 200, but not limited to this. The number of the display panels 200 of the tiled display device can be adjusted according to different product designs.

The tiled display device 10 further includes a plurality of connectors 150 removably secured to the frame member 100. For example, tiled display device 10 may also include a plurality of locking attachments 170. The locking members 170 pass through the frame member 100 and are respectively locked to the plurality of connection members 150 such that the connection members 150 are fixed to the frame member 100. In the present embodiment, the locking member 170 is, for example, a screw, and is provided with a threaded end, and the connecting member 150 is provided with a screw hole (as shown in fig. 3B) that mates with the threaded end of the locking member 170, but is not limited thereto.

In this embodiment, the connecting member 150 may protrude from the frame member 100 to be exposed in the opening 100OP of the frame member 100. It is particularly noted that the connecting member 150 has a hole 150h exposed in the opening 100OP of the frame member 100, and the hole 150h overlaps a portion of the surface of a corresponding display panel 200. The hole 150h is provided with an adhesive layer 190, and the connector 150 is connected to the display panel 200 overlapped with the adhesive layer 190 (as shown in fig. 4A). In other words, the display panel 200 is fixed to the frame member 100 by an adhesive relationship with the connection member 150.

Referring to fig. 4B, when an abnormality occurs in a portion of the display panel 200 (e.g., an abnormal display panel 200X) of the tiled display device 10 and cannot be repaired, the abnormal display panel 200X can be removed by releasing the connection relationship between the connecting member 150 adhered to the abnormal display panel 200X and the frame member 100. For example, the locking member 170 can be removed to release the locking relationship between the connecting member 150 and the frame member 100, so as to remove the abnormal display panel 200X. Accordingly, reworkability of the tiled display device 10 can be greatly improved, and further maintenance cost can be reduced.

Fig. 5A is a perspective view of another modified embodiment of the tiled display device of fig. 3A. Fig. 5B is a schematic cross-sectional view of the tiled display device of fig. 5A. Referring to fig. 5A and 5B, in a modified embodiment of fig. 3A, a height adjusting member 160 may be optionally disposed between the locking member 170A and the frame member 100A. More specifically, the height adjustment member 160 is disposed through the frame member 100A, and the locking member 170A is locked to the connecting member 150 through the height adjustment member 160. In the embodiment of fig. 5B, the height adjusting member 160 is, for example, a height adjusting screw, and is provided with a threaded portion, and the frame member 100A is provided with a threaded hole matching with the threaded portion of the height adjusting screw, but is not limited thereto.

Particularly, the height adjusting member 160 can be used to adjust the height of the corresponding display panel 200 on the frame member 100A, so as to reduce the height difference (i.e. the step difference) between the display panel 200 and the adjacent display panel 200, which is helpful to improve the surface flatness of the overall display device.

Fig. 6A to 6D are schematic cross-sectional views illustrating a process of fabricating a display panel by using an automatic stitching apparatus according to an embodiment of the present invention. Fig. 7A and 7B are schematic bottom views of the alignment mechanism of fig. 6B for controlling the movement and rotation of the stage.

Referring to fig. 6A, the automatic stitching device 300 is suitable for stitching the aforementioned stitched display apparatus 10 of fig. 1, and includes a clamping mechanism 305, a first moving mechanism 310, a second moving mechanism 320, a plurality of image capturing elements 330, a dispenser 340, an alignment mechanism 370 and a carrier 380. The clamping mechanism 305 is adapted to clamp the frame 100 of fig. 4A. For example, although not shown, the clamping mechanism 305 may be fixed on the base platform 301 of the automatic splicing apparatus 300, but is not limited thereto. In another embodiment, the clamping mechanism 305 may be disposed on a moving mechanism (not shown) and move relative to the base platform 301 to achieve the feeding and discharging of the frame 100.

The image capturing devices 330 and the dispenser 340 are disposed on the first moving mechanism 310. The alignment mechanism 370 and the stage 380 are disposed on 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.

For example, the frame 100 has a receiving surface 100bs on a side facing the carrier 380, and the frame 100 is provided with a plurality of connectors 150 on a side of the receiving surface 100 bs. The first moving mechanism 310 is adapted to drive the image capturing devices 330 and the dispenser 340 to move along a first direction D1 and a second direction D2 parallel to the receiving surface 100bs of the frame 100 above the frame 100. The second moving mechanism 320 is adapted to drive the alignment mechanism 370 and the carrier 380 to move along a first direction D1 and a second direction D2 parallel to the receiving surface 100bs of the frame 100 and a third direction D3 perpendicular to the receiving surface 100bs under the frame 100. In the present embodiment, the first direction D1, the second direction D2 and the third direction D3 may be selectively perpendicular to each other, but is not limited thereto.

The alignment mechanism 370 is disposed on the second moving mechanism 320. The carrier 380 is disposed on the alignment mechanism 370 and is adapted to carry the display panel 200. In the present embodiment, the number of carriers 380 for the display panel 200 is exemplarily described by taking one example, and the present invention is not limited thereto. In other embodiments, the number of the display panels 200 that can be placed on the carrier may be plural.

The alignment mechanism 370 is adapted to move the carrier 380 along at least one direction parallel to the receiving surface 100bs of the frame 100. For example, in the present embodiment, the alignment mechanism 370 is adapted to drive the carrier 380 to move along the first direction D1 and the second direction D2 and rotate along the rotation axis RX perpendicular to the receiving surface 100 bs.

As shown in fig. 7A, in detail, the alignment mechanism 370 may include two first slide rail mechanisms 371a, 371b and two second slide rail mechanisms 372a, 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 the present 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 the first direction D1 or the opposite direction thereof under the driving of the first slide rail mechanisms. The carrier 380 is disposed on the sliders of the two second slide rail mechanisms 372a and 372b, and is driven by the second slide rail mechanisms to move along the second direction D2 or the opposite direction thereof.

It is particularly noted that in the present embodiment, actuation of the second slide rail mechanism 372a and the second slide rail mechanism 372b of the alignment mechanism 370 may also be operated synchronously and reversely. For example, as shown in fig. 7B, the slider of the second slide rail mechanism 372B moves along the second direction D2, and the slider of the other second slide rail mechanism 372a moves in the opposite direction (i.e., direction D2 ") of the second direction D2. Thus, the carrier 380 is driven to rotate clockwise along the rotation axis RX, and otherwise, the carrier 380 is driven to rotate counterclockwise along the rotation axis RX (not shown).

An exemplary description will be made below regarding a splicing process of the display panel 200 on the frame member 100.

Referring to fig. 6A and 6B, the second moving mechanism 320 is moved to the lower side of the clamping mechanism 305 along the first direction D1. When the display panel 200 on the carrier 380 is overlapped with one of the openings 100OP of the frame member 100, the second moving mechanism 320 further drives the carrier 380 to lift along the third direction D3, so that the display panel 200 is as close to but not in contact with the connecting member 150 on the frame member 100 as possible.

Then, the plurality of image capturing elements 330 on the first moving mechanism 310 are utilized to capture images of a plurality of alignment marks (not shown) on the display panel 200 and confirm the deviation 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, and even rotate the stage 380 along the rotation axis RX, so as to move the display panel 200 on the stage 380 to a desired position.

After the alignment is completed, the dispenser 340 is moved to above the connector 150 overlapping the display panel 200, as shown in fig. 6C. After the dispenser 340 reaches the position, it is lowered to a position close to the connection member 150, and the adhesive 190M is injected into the hole 150h of the connection member 150. It is particularly noted that the adhesive 190M contacts a portion of the surface of the display panel 200 located in the hole 150h and the sidewall of the connecting member 150 defining the hole 150h, and is cured to form an integral adhesive layer 190, as shown in fig. 6D.

In this embodiment, the automatic splicing apparatus 300 may further include a curing member 350 movably disposed on the first moving mechanism 310 and adapted to cure the adhesive layer 190. For example, after the injection of the adhesive 190M (as shown in fig. 6C) is completed, the curing element 350 is moved over the connection 150 with the adhesive 190M injected into the hole 150 h. After the curing member 350 reaches the position, it is lowered to a position close to the connection member 150, and ultraviolet light is irradiated to the adhesive 190M in the hole 150h, so that the adhesive 190M is cured into the adhesive layer 190. That is, the curing element 350 of the present embodiment may be an ultraviolet light source, but is not limited thereto.

The connection between the other connecting members 150 and the display panel 200 can be realized by repeating the steps shown in fig. 6C and fig. 6D, and the description thereof will be omitted. After the connection of the display panel 200 and all the corresponding connectors 150 is completed, a splicing step of the display panel 200 on the frame member 100 is completed. The steps of fig. 6A to 6D are repeated, so that the plurality of display panels 200 can be spliced and fixed on the frame member 100, and the spliced display device 10 of fig. 2 is completed.

Particularly, since the display panel 200 and the connecting member 150 are connected by dispensing, the production efficiency and the reworking convenience of the tiled display device 10 can be increased.

Fig. 8 is a schematic diagram of a portable film changer according to an embodiment of the invention mounted on the tiled display device of fig. 2. Fig. 9A to 9C are schematic cross-sectional views illustrating a splicing process of the repair display panel by using the portable film changer of fig. 8.

Fig. 8 and 9A illustrate a portable film changer 400 that can be mounted on the tiled display device 10. When an abnormality occurs in a portion of the display panels (e.g., the abnormal display panel 200X of fig. 4B) in the tiled display device 10 and cannot be repaired, a maintainer can directly perform replacement operation of the abnormal display panels by using the portable film changer 400 in the installation area of the tiled display device 10.

Referring to fig. 8 and 9A, in detail, the portable film changer 400 includes a base 401, an alignment mechanism 470, a carrier 480, and a plurality of image capturing devices 430. The base 401 is detachably fixed to the frame member 100 of the tiled display device 10. The alignment mechanism 470 and the image capturing devices 430 are disposed on the base 401. The stage 480 is disposed on the alignment mechanism 470, and a receiving surface 480bs facing away from the alignment mechanism 470 is adapted to receive the repair display panel 200R.

It is particularly noted that the portable disc changer 400 further includes a plurality of support columns 410 connected to the base 401. When the portable film changer 400 is mounted on the frame 100, the support columns 410 are separated from the frame 100 by a space SP between the base 401 and the frame 100, and the space SP is provided with an alignment mechanism 470.

The portable disc changer 400 may be locked to the frame member 100 by a plurality of locking attachments 405. For example, the base 401 has a hole 401h at a portion where the support column 410 is connected, and the locking member 405 (e.g. a fixing screw) can pass through the hole 401h of the base 401 and the support column 410 and be locked on the frame 100, so that the portable disc changer 400 is fixed on the frame 100.

The alignment mechanism 470 is adapted to drive the carrier 480 to move along a first direction D1 and a second direction D2 parallel to the receiving surface 480bs, and rotate about a rotation axis RX perpendicular to the receiving surface 480 bs. Since the alignment mechanism 470 of the portable film changer 400 is similar to the alignment mechanism 370 of the automatic splicing apparatus 300, please refer to the related paragraphs in detail, and the detailed description is omitted here.

The following will exemplarily describe a film exchange process of the portable film exchange apparatus 400. First, as shown in fig. 4B, the connection relation between the connector 150 attached to the abnormal display panel 200X and the frame 100 is released to remove the abnormal display panel 200X. For example, the locking member 170 can be removed to release the locking relationship between the connecting member 150 and the frame member 100, so as to remove the abnormal display panel 200X.

It is noted that, after the abnormal display panel 200X is removed, the connector 150 connected to the abnormal display panel 200X on the original frame 100 is also removed (as shown in fig. 4B). Therefore, before the film changing process starts, the plurality of connecting members 150 need to be re-locked on the frame member 100 for the connection of the display panel to be replaced later.

After the abnormal display panel 200X is removed, the portable film changer 400 is installed and fixed on the side of the frame member 100 facing away from the display panel 200. As shown in fig. 9A, the portable film changer 400 mounted on the frame member 100 has a carrier 480 adapted to pass through the opening 100OP of the frame member 100 and protrude to a side of the frame member 100 away from the base 401 to receive the repair display panel 200R.

It is noted that the stage 480 protrudes from the opening 100OP to a degree that can maintain a small gap between the repair display panel 200R and the connector 150 on the frame member 100, so as to facilitate the subsequent alignment operation.

After the portable film changer 400 finishes film taking, the plurality of image capturing elements 430 are utilized to capture images of a plurality of alignment marks (not shown) on the repair display panel 200R and confirm the offset condition between the current position and the ideal position of the repair display panel 200R. If the alignment mechanism 470 is shifted, the stage 480 is moved along the first direction D1 and/or the second direction D2, and even the stage 480 is rotated about the rotation axis RX, so that the repair display panel 200R on the stage 480 is moved to a desired position.

After the alignment is completed, the adhesive 190M is injected into the holes 150h of the corresponding plurality of connectors 150 by using the (hand-held) dispenser 440, and cured to form the adhesive layer 190 connecting the repair display panel 200R and the connectors 150. The adhesive 190M may be cured by irradiation (e.g., ultraviolet light or laser) similar to that of fig. 6D, moisture-absorbing, or other curing method suitable for use in place, but the invention is not limited thereto. Therefore, the adhesive 190M can be selected according to different curing methods.

Referring to fig. 9C, after the repair display panel 200R is connected to the frame member 100, the locking attachment 405 is removed to release the locking relationship between the portable film changer 400 and the frame member 100. Thus, the film-changing process of the tiled display device 10 is completed.

Since the portable film changer 400 can be mounted on the frame member 100 of the tiled display device 10 and is equipped with the alignment mechanism 470 and the image capturing device 430, the tiled accuracy of the repair display panel 200R on the frame member 100 can be significantly improved.

In summary, in the tiled display device according to an embodiment of the invention, the display panel for stitching is fixed on the frame through the plurality of connectors. When the display panel of the spliced display device is abnormal and cannot be repaired, the display panel which cannot normally operate can be removed by releasing the connection relation between the connecting piece and the frame piece. Accordingly, reworkability of the tiled display device can be greatly improved. In addition, the display panel and the connecting piece are connected in a dispensing mode, so that the production efficiency and the reworking convenience of the spliced display device can be improved. Based on the structural characteristics, the invention further provides automatic splicing equipment capable of rapidly and accurately producing the spliced display device. In order to replace the display panel in the installation place of the spliced display device, the invention also provides portable film changing equipment. Because the portable film changing equipment can be erected on the frame piece of the spliced display device and is provided with the aligning mechanism and the image capturing element, the splicing precision of the display panel for repairing can be obviously improved.
