In terms of the current technical level, the BM (black matrix) area of the panel selected by the tiled screen 10 cannot be infinitely reduced to nothing, when two or more tiled units are tiled to form an oversized display device, a tiled gap 20 exists at the tiled position, and in addition, the frame distance from the edge of the visible area of the display device to the edge of the display device can make the whole tiled picture have a picture segmentation feeling, so that the whole tiled picture cannot be continuous visually, and the whole display effect of the tiled display picture is seriously affected. In view of this, the present invention provides a seamless tiled display device.
Referring to fig. 1, in an embodiment of the present invention, the seamless tiled display device includes a plurality of tiled screens 10, a first driving circuit (not shown), a plurality of display bars 30, a second driving circuit (not shown), and a main control board (not shown). A plurality of spliced screens 10 are spliced with each other to define a display area, a splicing gap 20 exists between two adjacent spliced screens 10, and a display bar 30 is fixed at the splicing gap 20. The first driving circuit, the second driving circuit and the main control board are arranged on the back of the seamless splicing display device, the first driving circuit is used for sending a first driving signal to the splicing screen 10 to display a picture, the second driving circuit is used for sending a second driving signal to the display strip 30 to display the picture, and the main control board is used for sending control signals to the first driving circuit and the second driving circuit respectively to enable the splicing screen 10 and the display strip 30 to synchronously display the picture under the driving of the first driving signal and the second driving signal.
According to the technical scheme, the display strips 30 capable of displaying pictures are fixed at the splicing gaps 20 of the spliced screens 10, the display pictures of the spliced screens 10 are driven by the first driving circuit, the display pictures of the display strips 30 are driven by the second driving circuit, and the first driving circuit and the second driving circuit are respectively controlled by the main control board, so that the spliced screens 10 and the display strips 30 synchronously display the pictures under the driving of the first driving signals and the second driving signals. Compared with the electronic compensation in the prior art, the method for eliminating the splicing gap 20 only visually by utilizing the light bars to illuminate the splicing gap 20 and weakening the black band formed at the edge of the splicing screen 10 has the advantages that the display bars 30 fixed at the splicing gap 20 can synchronously display the pictures consistent with the splicing screen 10, so that the picture continuity of the whole splicing display device at the splicing gap 20 is realized, the picture splitting sense of the splicing display device at the splicing gap 20 is eliminated, and the continuous and natural seamless picture display is really realized.
Specifically, the tiled display 10 includes an LCD panel and an LED panel, and the LED panel includes a mini-LED panel, a micro-LED panel, an OLED panel, and the like, and has a high resolution, a good color display on the screen, and a good image display effect in the application of the tiled display device. The display bar 30 comprises a display bar of a plurality of LEDs, and further, the display bar 30 comprises a plurality of micro-LED display bars, which refer to a high-density micro-sized LED array integrated on a chip, such as an LED display screen, wherein each pixel can be addressed and driven to light up individually. The LED backlight source has the characteristics of high efficiency, high brightness, high reliability, short reaction time and the like, has the characteristic of self-luminescence without a backlight source, and has the advantages of energy conservation, simple mechanism, small volume, thinness and the like.
To further improve the picture continuity of the tiled display device, the area of the display bar 30 is equal to or larger than the area of the tiled slot 20. That is, the display bar 30 can completely cover the splicing gap 20, when displaying a picture, the splicing gap 20 will not be exposed, and the display picture of the display bar 30 driven by the second driving signal is displayed at the splicing gap 20 and is synchronous with the display picture of the splicing screen 10 driven by the first driving signal, so that the picture splitting feeling at the splicing gap 20 is reduced, and the picture continuity of the splicing display device is improved.
The thickness of the display bar 30 may be greater than or equal to or less than the thickness of the tiled screen 10, and the thicknesses of the plurality of tiled screens 10 are the same, and the thickness relationship between the display bar 30 and the tiled screens 10 is not limited herein.
Referring to fig. 1, the tiled display 10 has two common shapes according to different usage scenarios, wherein the first shape is a structure in which a surface frame 40 is wrapped around the edge of the display surface of the tiled display 10, and the second shape is a structure in which no surface frame 40 is disposed around the edge of the display surface of the tiled display 10.
The spliced screen 10 comprises a display screen 50 and a face frame 40 fixed on the edge of the display screen 50, the face frame 40 comprises a fixing portion 41 and a limiting portion 42, the limiting portion 42 abuts against the surface of the display screen 50, and when the spliced screens 10 are spliced mutually, the fixing portions 41 of the two adjacent spliced screens 10 abut against each other. Therefore, the picture crack feeling appearing when the picture is displayed is mainly caused by the distance from the splicing gap 20 at the splicing position and the distance from the edge of the visible area of the display device to the surface frame 40 at the edge of the display device, and the display strip 30 is adhered to the limiting part 42 of the adjacent splicing screen 10, so that the picture crack feeling caused by the widths of the splicing gap 20 and the surface frame 40 is compensated, and a coherent and natural picture display effect is formed.
When the edge of the tiled screen 10 has no surface frame 40, the tiled screen 10 includes the display screen 50, and the display strip 30 is adhered to the edge of the adjacent display screen 50 close to the splicing gap 20, that is, the display strip 30 is directly fixed on the tiled screen 10.
Specifically, the display strip 30 can be fixed in the splicing gap 20 through a double-sided adhesive tape or a dispensing manner, and the display strip 30 is fixed on the two adjacent splicing screens 10, so that the connection between the display strip 30 and the splicing screens 10 is more stable and firm, and the falling off of the display strip 30 due to external force is avoided. Of course, the display bar 30 may be fixed only at the edge of one of the two adjacent tiled screens 10, as long as the display bar 30 and the tiled screen 10 can be fixed.
Further, in order to solve the heat dissipation problem when the display strip 30 is used, on one hand, when the display strip 30 is adhered to the splicing gap 20, an adhering material with high thermal conductivity is adopted, for example, silver paste is selected when dispensing, so that a silver paste layer is coated between the display strip 30 and the splicing gap 20. The silver adhesive is mainly composed of epoxy resin, silver powder, a curing agent, an accelerant and other additives, can realize the fixing and electric conduction effects, and has the advantages of large heat conductivity coefficient, large bonding strength and the like. In the use process of the display bar 30, the heat emitted by the display bar 30 can be conducted out, and the problems of poor display picture and the like caused by overhigh heat of the display bar 30 are avoided.
On the other hand, the display bar 30 includes a substrate (not shown) and a chip (not shown) fixed to the substrate, which is a ceramic substrate. Specifically, the chip is used for showing, and the base plate provides fixed mounting position for the chip, in the course of working of showing strip 30, chooses for use the good base plate of heat dissipation. Taking the processing process of micro-LED display bars as an example, the micro-LED structure design is thinned, miniaturized and arrayed, and the size of the micro-LED structure design is only about 1-100 mu m grade; then, transferring the micro-led batch to a circuit substrate, wherein the substrate can be a hard and soft transparent or opaque substrate; then, the physical deposition process is used to complete the passivation layer and the upper electrodeAnd the packaging of the upper substrate completes the micro-led display with a simple structure. The heat dissipation substrate absorbs heat generated during the use of the display bar 30 and conducts the heat to the heat sink, thereby realizing heat exchange with the outside. Common heat dissipation substrate materials include silicon, metals (e.g., Al, Cu), ceramics (e.g., Al)2O3AlN, SiC), composite materials, and the like, preferably, a ceramic substrate may be selected.
Referring to fig. 2, when the pixel sizes of the display bar 30 and the tiled display screen 10 are the same, the driving timings of the first driving circuit and the second driving circuit are the same. The main control board respectively sends control signals with the same driving time sequence to the first driving circuit and the second driving circuit, so that the spliced screen 10 and the display bar 30 synchronously display the picture under the driving of the first driving signal and the second driving signal. Therefore, the display pictures of the spliced screen 10 and the display bars 30 can be synchronized, and the seamless spliced display pictures can be really realized.
When the pixel sizes of the display bar 30 and the tiled screen 10 are different, the driving timings of the first driving circuit and the second driving circuit are different. Specifically, when the size of the pixels of the display bar 30 is half of that of the tiled screen 10, the driving timings of the first driving circuit and the second driving circuit are adjusted so that the pixels of the two display bars display one picture pixel. When the size of the pixel of the display bar 30 is twice that of the tiled screen 10, the driving time sequence of the first driving circuit and the second driving circuit is adjusted, and 2 to 4 pixels on the edge of the tiled screen 10 are optimized and transited, so that two pixels on the edge of the tiled screen 10 close to the tiled gap 20 display one picture pixel, and one pixel on the display bar 30 displays one picture pixel. Thus, even if the pixel sizes of the display bar 30 and the tiled display screen 10 are different, a coherent and natural image display can be presented by performing an algorithm through the corresponding sequential circuits.
The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
