Description

[Technical Field]

[0001] The present invention relates to the technical field of display panel manufacturing, and particularly to a splicing display device. [Background technology]

[0002] With the development of display panel manufacturing technology, higher requirements are being put forward for both the display effect and the overall performance of display panels and display devices.

[0003] Due to the advantages of low cost and high resolution, conventional liquid crystal displays (LCDs) have been widely used, especially for outdoor displays. With the increasing demand for use, the size of outdoor display panels has gradually progressed from the original small standard size to larger, flatter, and more integrated panels. For larger panels, the corresponding manufacturing equipment cannot meet the demand. Therefore, in the prior art, to obtain a desired large-size display panel, multiple panels of different or the same size are generally spliced ​​together to obtain a single large panel for display. However, in the prior art, when splicing, a splicing seam occurs between two adjacent panels, and the four-sided frame of each panel has a certain width, preventing it from emitting light. When a different panel displays, neither the splicing seam nor the four-sided frame display properly. Furthermore, when a user views the screen, they can directly see the undisplayed area in between. Furthermore, when splicing, each panel is a relatively independent module that is only mechanically spliced ​​together, which makes it easy to complicate the design of the internal structure of the spliced ​​panel, making subsequent maintenance difficult and thereby reducing the overall performance of the panel.

[0004] In short, in the prior art, when splicing to form a large-sized display panel, splicing seams occur between adjacent panels, and the structure of the panel formed after splicing is complicated, which is detrimental to further improving the overall performance of the display panel. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

Furthermore, the terms "first" and "second" are for descriptive purposes only and do not indicate or imply relative importance or the number of technical features depicted thereby.

[0021] With the continuous development of display panel manufacturing technology, higher requirements are being put forward for both the performance and display effect of display panels and display devices.

[0022] In the prior art, in the process of splicing multiple small-sized display panels together to form a display panel of a larger size or specification, gaps often occur between two adjacent display panels during splicing. When the panels are displaying normally, the gaps prevent light from being emitted, which further reduces the display effect and quality of the large spliced ​​display panel. In addition, the internal structure of the panels is made more complicated during splicing, which is detrimental to further improving the overall performance of the display device.

[0023] The embodiments of the present application provide a splicing display device, which effectively improves the splicing effect of the splicing display device, and effectively simplifies the internal structure of the splicing display device, thereby improving the overall performance of the device.

[0024] As shown in FIG. 1, FIG. 1 is a schematic plan view of the splicing display device according to an embodiment of the present application. Specifically, the splicing display device includes a plurality of different panels. Each panel is small in size, and after the plurality of different display panels are spliced ​​together, a large display panel with a larger standard size is further formed. Here, during splicing, different numbers of panels can be selected and spliced ​​according to the required size. In the following embodiment, splicing four different display panels will be used as an example. Panels with other splicing numbers will not be further described here.

[0025] Specifically, the display panel has four splices. Optionally, the display panel includes a first sub-panel 1011, a second sub-panel 1012, a third sub-panel 1013, and a fourth sub-panel 1014. When the different sub-panels are spliced, the sub-panels are arranged side-by-side and then spliced. In this embodiment, the different sub-panels may have the same specifications, and each sub-panel may be independently illuminating. When each sub-panel is independently illuminating, the lighting effect of each sub-panel may be adjusted during use to achieve different display effects. Alternatively, multiple sub-panels may have the same lighting effect, i.e., when adjustments are made, the changes to each sub-panel are the same. In this case, the four sub-panels may be considered as a single entity, which simplifies the control process and ensures the consistency of the lighting effects of the panels. This will not be described further.

[0026] In this embodiment, when splicing, the first sub-panel 1011 and the second sub-panel 1012 are arranged side by side in the first row, and the third sub-panel 1013 and the fourth sub-panel 1014 are arranged side by side in the second row. At this time, the first sub-panel 1011, the second sub-panel 1012, the third sub-panel 1013 and the fourth sub-panel 1014 are spliced ​​to form a rectangular structure. At the same time, there is a splicing slit 20 between two adjacent sub-panels.

[0027] In the following embodiment, the splicing slit 20 includes a first splicing slit 201 and a second splicing slit 202. Here, the first splicing slit 201 is arranged in the width direction of the display panel, and the second splicing slit 202 is arranged in the length direction of the display panel, so the length of the first splicing slit 201 is shorter than the length of the second splicing slit 202. The width of the first splicing slit 201 may be set to be the same as the width of the second splicing slit 202.

[0028] In the embodiment of the present application, when splicing the four different sub-panels, the splicing can be achieved by installing fixing brackets at corresponding locations on the outer edges of the panels and placing the sub-panels on the corresponding fixing brackets. In the drawings, the supporting brackets are installed corresponding to the back surfaces of the panels and are not specifically shown.

[0029] Furthermore, as shown in FIG. 2, FIG. 2 is a schematic diagram of a splicing effect of another display device according to an embodiment of the present application. Referring to the drawing in FIG. 1, in the embodiment of the present application, each sub-panel includes a display area 401 and a frame area 402 disposed on at least one side of the display area 401. Specifically, the frame area 402 may be disposed around the display area and correspond to the four edges of each sub-panel. For each sub-panel, its frame area cannot display normally. After splicing, the frame areas of different sub-panels and the splicing slits between the two frame areas are further aligned, which further expands the non-display area of ​​the entire panel and further reduces the display effect of the panel.

[0030] At the same time, the splicing display device further includes a light-supplying module 222. Specifically, the light-supplying module 222 is installed correspondingly within the splicing slit. For example, the light-supplying module 222 includes a first light-supplying module 2221 and a second light-supplying module 2222, where the first light-supplying module 2221 is installed correspondingly within the first splicing slit 201, and the second light-supplying module 2222 is installed correspondingly within the second splicing slit 202. When the light-supplying modules are installed, they completely cover the corresponding splicing slit, and the light emitted from the light-supplying module is directed in the same direction as the light emitted from the light-emitting side of each sub-panel. In this way, when the light-supplying module 222 and each sub-panel operate normally, light is also emitted from within the splicing slit, ensuring that the light intensity within the corresponding area of ​​the splicing slit is the same as the light intensity within the display area of ​​the display panel. And the display effect of the panel is guaranteed.

[0031] Furthermore, when the light-supplying module 222 is installed, the light-supplying module further includes a plurality of light-emitting units 403. The light-emitting units 403 can emit light to the outside, thereby realizing the light-supplying function of the light-supplying module 222 and reducing the display problem in the splicing slit area.

[0032] Specifically, the light-supplying module 222 may be installed as a light-emitting lamp board, for example, an LED lamp board or a Micro-LED lamp board, with a plurality of light-emitting units 403 installed on the lamp board, each light-emitting unit corresponding to an LED lamp bead. In the embodiments of the present application, the light-emitting units 403 may be installed on the driving board of the light-supplying module. In the following embodiments, the light-supplying module 222 will be described using an LED lamp board as an example, with a plurality of LED lamp beads installed on the LED lamp board to achieve the light-supplying effect of the lamp board.

[0033] In the embodiment of the present application, the plurality of light emitting units 403 may be arranged in one or more rows on the corresponding lamp board, thereby adjusting the light beam in the splicing slit according to different lighting situations.

[0034] 2, when the light-filling module is installed, the opposing sides of the light-filling module 222 are attached within the frame areas of the corresponding sub-panels. For example, the left side of the first light-filling module 2221 is attached within the frame areas 402 of the first sub-panel 1011 and the third sub-panel 1013 at the same time, without overlapping with the display area, for example, the left side of the first light-filling module 2221 is flush with the boundary of the display area of ​​the first sub-panel, and the right side of the first light-filling module 2221 is attached within the frame areas 402 of the second sub-panel 1012 and the fourth sub-panel 1014 at the same time, without overlapping with the display area, for example, the right side of the first light-filling module 2221 is flush with the boundary of the display area of ​​the second sub-panel. This completes the installation and fixing of the first light-filling module 2221, and similarly, the second light-filling module 2222 is attached and fixed in the same manner. In this embodiment, when the light-filling module is activated, it can simultaneously fill the frame area of ​​each sub-panel and the splicing slit area between adjacent sub-panels, thereby achieving a lighting effect consistent with the display area of ​​the display panel.

[0035] In the embodiment of the present application, when the light-supplying module is fixed according to the above method, the height of the light-supplying module is limited, specifically, the height of the light-supplying module is not more than 10 mm. Optionally, the height of the light-supplying module 222 is set to 1 mm or 3 mm, thereby effectively reducing the height difference between the light-supplying module and the surface of the sub-panel and ensuring the display effect.

[0036] As shown in FIG. 6, FIG. 6 is a structural schematic diagram of a second supplementary lighting module according to an embodiment of the present application. In this embodiment, when each light-emitting unit 403 is installed, the light-emitting unit 403 includes a plurality of sub-pixels of different colors. In the following embodiment, the light-emitting units 403 may be installed at equal intervals on the second supplementary lighting module 2222. At the same time, a driver chip 601 is included in the light-emitting unit 403. In this embodiment, the driver chip 601 may be installed on the driver board together with the light-emitting units. The driver board is mainly a carrier board, and certain wiring may be installed on the driver board to facilitate the corresponding electrical connection between the driver chip and the terminals of the light-emitting units. At the same time, a blue sub-pixel 602, a green sub-pixel 603, and a red sub-pixel 604 are further installed in the light-emitting unit 403.

[0037] Specifically, when the above structure is installed, the driver chip 601, the blue sub-pixel 602, the green sub-pixel 603, and the red sub-pixel 604 may be arranged in parallel within the light-emitting unit 403, for example, in a single vertical or horizontal row, or, depending on the size of the light-emitting unit 403, the light-emitting units and driver chips may be arranged in a multi-row or multi-column structure, and during installation, the different color sub-pixels may be arranged rationally according to the needs of different products, which will not be described further herein.

[0038] In this embodiment, the driver chip 601 is electrically connected to the blue sub-pixels 602, green sub-pixels 603, and red sub-pixels 604, respectively, and is packaged together with the blue sub-pixels 602, green sub-pixels 603, and red sub-pixels 604 in the same light-emitting unit 403. When each sub-panel displays and works normally, each light-emitting unit 403 in the second supplementary light module emits light, and the driver chip 601 can adjust the light-emitting status of each light-emitting unit 403, thereby effectively improving the display effect in the display area and the splicing slit and ensuring the consistency of the light-emitting effect.

[0039] As shown in Figure 3, Figure 3 is a schematic diagram of the circuit structure in the light emitting unit according to an embodiment of the present application. Referring to the structures in Figures 1 to 3, in the embodiment of the present application, a corresponding driving chip is integrated and packaged in each light emitting unit, so that the number of circuits and connecting members in the supplementary light module can be further reduced, and the purpose of further simplifying the device structure can be achieved.

[0040] Specifically, for the second light supplementary module, a plurality of light emitting units may be disposed on the second light supplementary module, for example, an m*n rectangular array may be disposed on the second light supplementary module, where m is the corresponding number of rows, which may be between 1 and 50, and n is the corresponding number of columns, which may be between 50 and 512. In the following embodiment, m=6 and n=360 are used as an example, and other numbers of rows or columns may be used with reference to the methodology of the present application.

[0041] In the present embodiment, the spacing between the light emitting units in two adjacent rows may be set to the same distance, and the spacing between the light emitting units in two adjacent columns may be set to the same distance. Each light emitting unit is provided with a corresponding signal line to control the light emitting unit.

[0042] Specifically, the splicing display device includes a power supply voltage line Vcc, a first voltage signal line 333, a second voltage signal line 334, a third voltage signal line 335, and a GND signal line 336. Here, one power supply voltage line Vcc is installed corresponding to each row, for example, the power supply voltage line Vcc is installed between two adjacent rows and extends to one edge of the light supplement module, and the power supply voltage line Vcc is electrically connected to the light emitting units in that row, and power is supplied to the light emitting units through the power supply voltage line Vcc.

[0043] At the same time, the first voltage signal line 333 is installed at the top edge of one side of the light supplementary module, for example, at a location close to the top edge of the second light supplementary module 2222. After the installation is completed, multiple lead wires are drawn out from the first voltage signal line 333 at locations corresponding to each column, and each lead wire is installed corresponding to and electrically connected to the light emitting units of the column.

[0044] Furthermore, a second voltage signal line 334, a third voltage signal line 335, and a GND signal line 336 are sequentially arranged near the bottom edge of the second supplementary light module 2222. Specifically, the second voltage signal line 334 and the third voltage signal line 335 may be arranged above the GND signal line 336, thereby ensuring that the GND signal line 336 can properly perform the grounding function and ensure the normal operation of the supplementary light module.

[0045] In this embodiment, second lead wires 42 are provided at locations corresponding to each column of the second voltage signal line 334, and third lead wires 43 are provided at locations corresponding to each column of the third voltage signal line 335. Here, the second lead wires 42 and the third lead wires 43 are electrically connected to the light-emitting units of each column.

[0046] Specifically, each light-emitting unit 403 is provided with a driver chip 601, a blue sub-pixel 602, a green sub-pixel 603, and a red sub-pixel 604. Therefore, in this embodiment, different voltage signal lines are provided to achieve different control functions. In the first embodiment, see the connection scheme in FIG. 4 for details. The second voltage signal line 334 is electrically connected to the red sub-pixel 604 in the light-emitting unit via a lead wire, and the third voltage signal line 335 is electrically connected to the blue sub-pixel 602 and the green sub-pixel 603 in each column of the light-emitting units via a lead wire, so that the third voltage signal line 335 simultaneously provides control signals to the blue and green sub-pixels.

[0047] In the embodiment of the present application, by installing the second voltage signal line and the third voltage signal line, different light emitting units are connected in series or in parallel to realize control of the sub-pixels in different light emitting units, and each light emitting unit is electrically connected to a driving chip to realize independent control, and the same voltage signal line can realize control of multiple sub-pixels of different colors, which further effectively reduces the number of wires in the light supplementary module and the display device and effectively improves the control efficiency.

[0048] When the display panel corresponding to each sub-panel is to emit light normally, different control signals are provided to the power supply voltage line Vcc, the first voltage signal line 333, the second voltage signal line 334, the third voltage signal line 335 and the GND signal line 336, so that the sub-panel emits light and the light-supply module can emit light normally, thereby improving the display effect of the splicing slit area.

[0049] In this embodiment, when the corresponding voltage signal lines are installed, the voltage values ​​in two adjacent rows can be the same. For example, in the first and third rows, the voltage values ​​provided on the first voltage signal line 333, the second voltage signal line 334, or the third voltage signal line 335 corresponding to the light emitting units are the same. This ensures that the first and third rows have the same lighting effect. At the same time, the corresponding voltage values ​​in the second and fourth rows can be the same or different from the voltage values ​​in the first and third rows, which allows adjustment for different light emitting units and allows adjacent rows to be installed in different control modes, thereby achieving various control effects for the light supplementary module, ensuring the display effect of the splicing slit area, and improving the user experience.

[0050] When the display panel emits light normally, the display panel formed after splicing has a first control timing, scans the liquid crystal in the panel at the first control timing, and emits light normally. In this embodiment, each light-emitting unit is provided with a driver chip 601, and the first voltage signal line 333 provides the driver chip 601 with a second control timing, which enables each sub-pixel to emit light at the second control timing. In this embodiment, the first control timing and the second control timing can be the same, thereby ensuring that the display effect of the display area of ​​each sub-panel is the same as the light-emitting effect of the light-filling module in the splicing slit area and improving the overall performance of the panel.

[0051] 4, which is a schematic layout diagram of the internal circuit of another light emitting unit according to an embodiment of the present application. Referring to the layout structure in FIG. 3, in this embodiment, the first voltage signal line 333 and the third voltage signal line 335 are simultaneously electrically connected to the light emitting units in each column through corresponding lead lines. Specifically, the first voltage signal line 333 is simultaneously electrically connected to the driver chip 601 and the red subpixel 604, and the second voltage signal line 334 is simultaneously electrically connected to the blue subpixel 602 and the green subpixel 603. At this time, the red subpixel and the driver chip 401 have the same control signal, and the blue subpixel 602 and the green subpixel 603 have the same control signal. When the light module emits light normally, different control signals can be achieved for subpixels of different colors, resulting in different light emitting effects.

[0052] In this embodiment, a driver chip 601 is installed in each light-emitting unit, and the driver chip 601 is connected to a corresponding sub-pixel of a different color to achieve different control effects. At the same time, this structure further reduces the number of wiring lines on the panel, and the wiring is integrated and installed on the back side of the light-filling module, simplifying the panel structure. Furthermore, to improve the consistency of the display effect between the light-filling module and the display area, the control timing of at least some of the driver chips 601 is the same as that of the display panel, thereby improving the display effect of the entire display panel.

[0053] As shown in Figure 5, Figure 5 is a schematic diagram of a splicing structure according to an embodiment of the present application. Referring to the structures in Figures 1 to 3, in this embodiment, when different light supplementary modules are installed in corresponding splicing slits, for example, a second light supplementary module 2222 is installed in the second splicing slit 202, and a support block 504 is further installed in the second splicing slit 202, and the multiple support blocks 504 are installed in the splicing slit at intervals. For example, the support blocks 504 are installed at equal intervals, and by installing them at intervals, the total weight of the support blocks 504 can be reduced, resulting in a lighter and thinner splicing panel.

[0054] Furthermore, to ensure the splicing effect, in this embodiment, when multiple support blocks 504 are installed, engagement grooves 505 are further installed on the surfaces facing the light-emitting side of the support blocks 504. After the support blocks 504 are engaged in the splicing slits, the corresponding light supplementary modules are further engaged in each engagement groove 505 to secure the light supplementary modules and complete the splicing of the entire splicing device.

[0055] In this embodiment, the arrangement density of the support blocks 504 in the first splicing slit 201 and the second splicing slit 202 may be the same, thereby ensuring the consistency of different areas of the splicing device. Furthermore, when different supplementary light modules are installed, such as a first supplementary light module and a second supplementary light module, the number of light emitting units in the first supplementary light module within a unit length is the same as the number of light emitting units in the second supplementary light module. In this way, when the different supplementary light modules are operated simultaneously, they have a consistent display effect, which further ensures the consistency of the display effect of the entire splicing display device.

[0056] 7, which is another structural schematic diagram of the optical fiber module according to an embodiment of the present application. Referring to the structures in FIGS. 1 to 4, in this embodiment, the splicing display device further includes a connector 621, a receiving card 622, and a transmitting card 623.

[0057] Specifically, the connector 621 may be installed on the rear surface of the corresponding lighting module, while the receiving card 622 and the transmitting card 623 may be installed on the rear surface of the lighting module or elsewhere on the display panel. When installed, the connector 621 is electrically connected to the lighting module, specifically, the connector 621 is electrically connected to the power supply voltage line Vcc of the lighting unit to provide a control signal to the lighting unit. In this embodiment, the connection port of the connector 621 may be configured as an integrated port, and when electrically connected, the connection port of the connector 621 is connected to the lead terminal of the lighting unit in the lighting module, thereby effectively reducing the number of lines arranged on the display panel and simplifying the structural complexity of the splicing display panel.

[0058] At the same time, the receiving card 622 is electrically connected to the connector 621, and the transmitting card 623 is electrically connected to the receiving card 622. Here, the transmitting card 623 provides a control signal to the receiving card 622, and each transmitting card can be electrically connected to multiple receiving cards 622 at the same time, and the same receiving card 622 can be electrically connected to multiple connectors 621, and controls the driving chip in the light emitting unit to ensure normal light emission of the supplementary light module, and adjusts and controls the light emission effect during light emission to ensure good consistency of the splicing display device, effectively simplifying the splicing structure of the splicing display device and improving its overall performance.

[0059] Furthermore, in the embodiments of the present application, the splicing display device can be applied to any product or component that can be displayed or has a splicing folding function, such as a computer, electronic paper, a display, a laptop, a digital photo frame, etc., and the specific type is not specifically limited.

[0060] In summary, the splicing display device according to the embodiment of the present invention has been introduced in detail above.
