Based on the embodiments herein, a person of ordinary skill in the art would be able to obtain all other embodiments based on the disclosure herein, which are within the scope of the disclosure herein.
As shown in fig. 1 and 2, an embodiment of the first aspect of the present application proposes a spliced screen. The spliced screen comprises at least two mutually spliced sub-display screens 100, a spliced seam 200 is formed between two adjacent sub-display screens 100, an adhesive tape assembly is arranged in the spliced seam, and a fluorine-containing solvent is coated on the side wall of one side of the sub-display screen, which is close to the adhesive tape assembly.
According to the spliced screen in the embodiment of the application, the adhesive tape assembly 400 is disposed in the spliced seam 200, and the side wall of the sub-display screen 100 close to one side of the adhesive tape assembly is coated with the fluorine-containing solvent 300, that is, in the embodiment, the sub-display screen 100 performs edge sealing treatment by a combination manner of the fluorine-containing solvent 300 and the adhesive tape assembly 400. In the related art, the edge sealing technology of the display screen mostly adopts a process of coating edge sealing glue on the side wall of the display screen, and the thickness of the edge sealing glue cannot be thinned under the influence of a glue coating process and equipment precision. The side wall of the sub-display 100 in this embodiment is coated with the fluorine-containing solvent 300, so that water vapor can be prevented from entering, which causes corrosion of the internal circuit of the sub-display 100, and the width of the splice joint 200 can be reduced better due to the thinner thickness of the fluorine-containing solvent 300, so that the display effect of the splice can be improved.
In some specific embodiments, the fluorine-containing solvent 300 may be an electronic grade fluorine-containing solvent 300 that is used for moisture and corrosion protection of printed circuit boards and electronic components. Specifically, the fluorine-containing solvent 300 may be a fluorine-containing polymer using hydrofluoroether as a solvent, and after the fluorine-containing solvent 300 is coated on the sidewall of the sub-display 100, a very thin film having excellent water-and oil-repellent properties and which does not require an additional curing process is formed rapidly, and is very easy to coat, remove and repair. In some specific embodiments, the coating thickness of the fluorine-containing solvent may be 0.5 μm to 5 μm, and it can be seen that compared to the spliced screen sealed with the encapsulation adhesive in the related art, the spliced seam 200 of the spliced screen in this embodiment is narrower, so that the display effect of the spliced screen can be improved. And the solvent and the polymer in the fluorine-containing polymer taking the hydrofluoroether as the solvent are very safe and low-toxicity substances, do not destroy the ozone layer, and are beneficial to environmental protection. Still further, in some embodiments, the fluorine-containing solvent 300 has a fuel group added thereto, which can fluoresce under ultraviolet irradiation, which is advantageous for coating detection and quality monitoring in the production process.
In some embodiments of the present application, the tape assembly 400 includes an aluminum foil tape 410, one side of the aluminum foil tape 410 being in close contact with the fluorine-containing solvent 300. In this embodiment, the substrate of the aluminum foil tape 410 is aluminum foil, and the adhesive layer uses pressure sensitive adhesive. The aluminum foil tape 410 can effectively shield electromagnetic interference, and can prevent static electricity from forming and releasing, so that the side wall of the sub-display 100 can be protected to avoid causing electrostatic breakdown problem.
In some embodiments of the present application, the tape assembly 400 includes an aluminum foil tape 410 and an elastic tape 420, the elastic tape 420 is disposed between the fluorine-containing solvent 300 and the aluminum foil tape 410, one side of the aluminum foil tape 410 is closely adhered to the elastic tape 420, and one side of the elastic tape 420 remote from the aluminum foil tape 410 is closely adhered to the fluorine-containing solvent 300. In this embodiment, the elastic tape 420 is a tape having a certain elastic function. Because the aluminum foil tape 410 is made of a hard material, and the elastic tape 420 has good flexibility, when the side wall of the display screen adhered with the elastic tape 420 expands with heat and contracts with cold, the elastic tape 420 can expand or contract with the side wall of the sub display screen 100, thereby avoiding the problem of glue opening of the tape assembly 400.
In some embodiments of the present application, one side of a sub-display is the binding side 110, wherein the binding side 110 of one sub-display is adjacent to the unbinding side 120 of another sub-display and forms the splice seam 200, and the sidewall of the unbinding side 120 adjacent to the splice seam 200 is coated with the fluorine-containing solvent 300. In this embodiment, bonding is also called Bonding, which means that the driving carrier is thermally bonded to the panel by using ACF (An isotropic Conductive Film, anisotropic conductive adhesive) under various conditions (temperature, pressure, time), and the Bonding mainly includes two main processes of ACF attachment and pressing (hot pressing), and the Bonding side 110 is a portion of the sub-display 100 that can be bonded to the driving carrier. In the related art, the display panel needs to be bound during the preparation, and mainly, the panel is connected with COF (chip on film 130), FPC (flexible circuit board) and the like through golden fingers, so that the panel has functions of power on, display, touch and the like. In this embodiment, the binding side 110 of one sub-display 100 is adjacent to the unbinding side 120 of the other sub-display 100, and a splice joint 200 is formed between the two sub-displays 100, and by coating the side wall of the unbinding side 120, which is close to the splice joint 200, with a fluorine-containing solvent 300, it is possible to prevent water vapor from penetrating into the side wall of the unbinding side 120 of the sub-display 100, thereby causing corrosion of the internal circuits of the sub-display 100.
In some embodiments of the present application, the sub-display 100 further includes a flip chip film 130, where the flip chip film 130 is disposed on a side wall of the bonding side 110 near the splice seam 200, and a side of the flip chip film 130 away from the bonding side 110 is coated with the fluorine-containing solvent 300. In the related art, the flip Chip Film 130 is also called COF (Chip On Flex, or Chip On Film), and the COF technology generally refers to manufacturing a driving circuit On the flip Chip Film 130, and the flip Chip Film 130 is directly connected to a display panel to electrically connect the driving circuit and the display panel. In this embodiment, the flip-chip film 130 is connected to the sub-display 100 to realize the electrical connection between the driving circuit and the sub-display 100, and in particular, the flip-chip film 130 is disposed on the side wall of the binding side 110, so that the side wall of the binding side 110 does not need to be coated with the fluorine-containing solvent 300 to ensure good electrical connection between the flip-chip film 130 and the sub-display 100, and the side of the flip-chip film 130 away from the binding side 110 needs to be coated with the fluorine-containing solvent 300, so that water vapor can be prevented from invading from the side of the flip-chip film 130, and corrosion of the internal circuits of the flip-chip film 130 and the sub-display 100 is caused. In some specific embodiments, the tape assembly 400 includes an aluminum foil tape 410 and an elastic tape 420, and the elastic tape 420 and the aluminum foil tape 410 are sequentially attached to the side of the fluorine-containing solvent 300 away from the flip chip film 130, in the related art, when the flip chip film 130 is cut, an electrode leaks out at the end face of the cut surface, and the aluminum foil tape 410 is a conductor and is easy to short-circuit with the electrode, so that by providing the elastic tape 420 between the aluminum foil tape 410 and the flip chip film 130, the short-circuit between the aluminum foil tape 410 and the flip chip film 130 can be avoided.
In some embodiments of the present application, the edges of the sub display 100 are provided with black matrix areas, the width of the black matrix areas at the edges of the binding sides 110 is 0.6mm, and the width of the black matrix areas at the edges of the unbinding sides 120 is 0.5mm. In the related art, the black matrix region is also called BM (Black Matrix), and the black matrix is used to separate the primary colors of red, green and blue (to prevent color confusion) in the color filter by means of a material with high light shielding performance, so as to prevent light leakage, thereby being beneficial to improving the contrast of each color block. In addition, in the TFT-LCD, the black matrix can also mask the internal electrode traces or the thin film transistors 142. In the present embodiment, the black matrix region is disposed at the edge of the sub-display 100 to hide the internal electrode trace or the thin film transistor 142, and also to prevent side light leakage. In some specific embodiments, the width of the black matrix area at the edge of the binding side 110 is 0.6mm, the width of the adhesive tape assembly 400 adhered to the side wall of the binding side 110 is about 0.2mm, the width of the black matrix area at the edge of the unbinding side 120 is 0.5mm, and the width of the adhesive tape assembly 400 adhered to the side wall of the unbinding side 120 is about 0.2mm, so that the overall width of the non-display area is about 1.6mm, and it can be seen that the width of the splice seam 200 is narrower in this embodiment, so that the display effect of the spliced screen can be further improved.
In some embodiments of the present application, the sub-display 100 is a thin film transistor 142 liquid crystal display. The TFT-LCD (Thin film transistor liquid crystal display) is also called as TFT-142, and has the advantages of high image quality, simple driving method, and rapid mass production, so that the sub-display panel 100 of the tiled display can be a TFT-142 lcd.
In some embodiments of the present application, the sub-display 100 is sequentially stacked with a first substrate 141, a thin film transistor 142, a color film substrate 143, and a second substrate 144 along a thickness direction, and sidewalls of the thin film transistor 142 and the color film substrate 143 are coated with a fluorine-containing solvent 300. In this embodiment, by coating the fluorine-containing solvent 300 on the sidewalls of the thin film transistor 142 and the color film substrate 143, it is possible to prevent moisture from penetrating into the thin film transistor 142 and the color film substrate 143 to cause corrosion.
In some embodiments of the present application, at least two sub-displays 100 have the same size in the length direction and/or at least two sub-displays 100 have the same size in the width direction. Illustratively, when the tiled screen has four sub-screens 100, the four sub-screens 100 have the same dimensions in the length direction and the same dimensions in the width direction, so that when the four sub-screens 100 are tiled together, a rectangular tiled screen can be formed. When the dimension along the length direction is the same as the dimension along the width direction, the spliced screen is square in shape.
Embodiments of the second aspect of the present application provide a display device, including the tiled screen in any of the embodiments of the first aspect.
According to the display device in the embodiment of the application, since the display device is provided with the spliced screen in any embodiment of the first aspect, the display device also has the beneficial effects of any embodiment of the first aspect. Specifically, in the spliced screen of the present embodiment, the side wall of the sub-display screen 100 is coated with the fluorine-containing solvent 300, and the tape assembly 400 is adhered to the side of the fluorine-containing solvent 300 away from the sub-display screen 100, that is, in the present embodiment, the sub-display screen 100 performs edge sealing treatment by means of a combination of the fluorine-containing solvent 300 and the tape assembly 400. In the related art, the edge sealing technology of the display screen mostly adopts a process of coating edge sealing glue on the side wall of the display screen, and the thickness of the edge sealing glue cannot be thinned under the influence of a glue coating process and equipment precision. The side wall of the sub display screen 100 in this embodiment is coated with the fluorine-containing solvent 300, so that water vapor can be prevented from entering, which causes corrosion of the internal circuit of the sub display screen 100, and the width of the splice seam 200 can be reduced better because the thickness of the fluorine-containing solvent 300 can be coated is thinner, so that the display effect of the splice screen can be improved, and the display device comprising the same can also improve the display effect.
