- the inorganic material film may be a single layer film of one of a metal oxide film, an oxide film of silicon, and a nitride film of silicon.
- the inorganic material film may be a multilayer film of at least two of a metal oxide film, an oxide film of silicon, and a nitride film of silicon.
- the metal oxide film may be an A1 2 0 3 film.
- the width of the sealant does not exceed 1 mm.
- the width of the inorganic material film is not more than 10 ⁇ m.
- Another aspect of the present invention provides a method for fabricating a display panel, comprising: providing a first substrate and a second substrate, and sealing the first substrate and the second substrate with a sealant, after the frame is sealed A film of an inorganic material is formed on the outer side of the sealant.
- an inorganic material is deposited on the outer side of the sealant by atomic layer deposition.
- a film of an inorganic material is deposited on the outer side of the sealant by chemical vapor deposition.
- the inorganic material film may be a single layer film of one of a metal oxide film, a silicon oxide film, and a silicon nitride film; or a metal oxide film or a silicon oxide film. And a multilayer film of at least two of silicon nitride films.
- Still another aspect of the present invention provides a display device using the above display panel.
- the outer surface of the sealant of the display panel of the embodiment of the invention is formed with an inorganic material film, and the inorganic material film has better water and oxygen barrier properties with respect to the sealant, thereby making the display panel laterally have better water and oxygen barrier. Sex. DRAWINGS
- FIG. 1 is a schematic structural view of a display panel of the prior art
- FIG. 2 is a schematic structural view of a display panel according to an embodiment of the present invention.
- FIG. 3 is a schematic structural view of another display panel according to an embodiment of the present invention. detailed description
- the display panel of the embodiment of the present invention includes: a first substrate 220 and a second substrate 230 that are framed by a sealant 240.
- the first substrate 220 is an OLED array substrate, which includes a pixel array formed by the OLED 210
- the second substrate 230 is a glass substrate, and the two substrates are surrounded by After the frame sealant 240 is framed, the OLED array is sealed between the two substrates.
- a film 250 of an inorganic material is further formed on the outside of the sealant 240 in this embodiment.
- the inorganic material film 250 is also sandwiched between the first substrate 220 and the second substrate 230, and surrounds the sealant 240 from the periphery to isolate the sealant 240 from the outside atmosphere.
- the inorganic material film 250 may be a metal oxide film, an oxide film of silicon or a nitride film of silicon. Since aluminum (A1) has chemical characteristics which are easily oxidized, and A1 2 0 3 has excellent water-blocking oxygen barrier property, preferably, the metal oxide film is an A1 2 0 3 film.
- a plurality of layers of inorganic material film may be formed on the outside of the sealant 240.
- two layers of inorganic material films are formed on the outer side of the sealant 240: a first inorganic material film 260 and a second inorganic material film 270 formed on the outer side thereof.
- the first inorganic material film 260 and the second inorganic material film 270 may be formed of different materials of a metal oxide film, a silicon oxide film, or a silicon nitride film, respectively.
- the first inorganic material film 260 and the second inorganic material film 270 are also sandwiched between the first substrate 220 and the second substrate 230, and surround the frame sealant 240 from the periphery to isolate the frame sealant 240 from the outside atmosphere. .
- the inorganic material film 250 is formed on the outer side of the sealant 240 of the display panel of the embodiment, and the inorganic material film 250 itself has better water and oxygen barrier properties, thereby making the display panel laterally have better water and oxygen barrier properties. .
- the width of the sealant 240 can be greatly reduced.
- the width may be, for example, not more than 1 mm, provided that the width of the sealant 240 allows the upper and lower panels to achieve sufficient adhesive strength.
- the thickness of the inorganic material film 250 can be as thin as ⁇ or less. Therefore, the sum of the width of the frame sealant and the width of the inorganic material film of the embodiment of the present invention is also much smaller than the width of the existing frame sealant as shown in FIG. 1, thereby maintaining a good water and oxygen barrier property. Next, reduce the width of the border of the display panel to realize a narrow border display panel.
- the sum of the width of the sealant 240 and the width of the inorganic material film 250 is W1. It is also much smaller than the width of the existing sealant as shown in FIG. 1; as shown in FIG. 3, the width of the sealant 240, the sum of the widths of the first inorganic material film 260 and the second inorganic material film 270, W2 It is also much smaller than the width of the existing sealant as shown in FIG.
- the embodiment of the present invention further provides a method for manufacturing a display panel, comprising: fabricating a first substrate and a second substrate, sealing the first substrate and the second substrate with a sealant, and sealing the frame after the sealing A film of an inorganic material is formed on the outer side of the sealant.
- the first and second substrates may also be substrates prepared in advance.
- the inorganic material film may be a single layer film of one of a metal oxide film, a silicon oxide film, and a silicon nitride film, or at least a metal oxide film, a silicon oxide film, and a silicon nitride film. Two multilayer films.
- the step of forming an inorganic material film on the outer side of the sealant may be performed by depositing an inorganic material film on the outer side of the sealant by atomic layer deposition (ALD). Since A1 2 0 3 can be conveniently fabricated by ALD, the following description will be made by taking the formation of the A1 2 0 3 film as an example.
- ALD atomic layer deposition
- the display panel encapsulated with the sealant is placed in the ALD chamber, and a reaction medium such as tri-methyl aluminum (TMA) or water is introduced into the ALD film formation process to perform atomic layer deposition layer by layer.
- a reaction medium such as tri-methyl aluminum (TMA) or water
- TMA tri-methyl aluminum
- Into A1 2 0 3 film Into A1 2 0 3 film.
- another reaction gas may be introduced, for example, Zr0 2 (passing ZrCl 4 and water) is deposited.
- the step of forming an inorganic material film on the outer side of the sealant may further deposit a film of the inorganic material on the outer side of the sealant by chemical vapor deposition (CVD).
- CVD chemical vapor deposition
- the sealant is first encapsulated display panel respectively into the CVD chamber into Si3 ⁇ 4, NH 3 and other reactant CVD film forming process to form SiN x films.
- other reaction gases may be introduced, such as depositing SiON x (passing into Si 3 ⁇ 4 and N 2 0 ).
- the embodiment preferably uses the ALD method to form the inorganic material. film.
- the embodiment of the invention further provides a display device using the above display panel, which may be: a liquid crystal panel, an electronic paper, an OLED panel, a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigation device, etc. Any product or part that has a display function.
