Description

Display floater and display unit

Technical field

The utility model relates to Display Technique field, particularly a kind of display floater and display unit.

Background technology

Existing display floater comprises two substrates mostly: first substrate and second substrate, two substrates surrounding is sealed frame by sealed plastic box and formed display floater.Organic Light Emitting Diode (Organic Light-Emitting Diode for example; OLED) display floater; first substrate is OLED array base palte, and second substrate is the glass substrate of protection use, and two substrates surrounding is sealed in OLED array between two substrates after sealing frame by sealed plastic box.Sealed plastic box is except sticking together two substrates, and another effect is to make display floater side direction have water proof oxygen barrier.But because the water proof oxygen barrier of this material of sealed plastic box own is poor, reduce water, the oxygen penetrance of display floater side direction, improve the life-span of display floater, just need to strengthen the width of sealed plastic box.As shown in Figure 1, be existing OLED display floater schematic diagram, comprising: the sealed plastic box 140 that is formed OLED array base palte 120, glass substrate 130 and the surrounding of pel array by some OLED110.The width W ＇ that can find out sealed plastic box 140 is larger, greatly about 2mm～3mm.

Although increase the width of sealed plastic box, intercepted to a certain extent seeing through of water, oxygen, due to the poor defect of the water proof oxygen barrier of sealed plastic box material own, after long-time use, also had water, oxygen sees through, well water proof oxygen barrier.Also make the border width of display floater increase, cannot produce popular at present narrow frame display floater simultaneously.

Embodiment

Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.

As shown in Figure 2, the display floater of the utility model embodiment, comprising: by first substrate 220 and the second substrate 230 of sealed plastic box 240 envelope frames.The OLED display floater of take (is not limited to oled panel as example, also can be liquid crystal panel), first substrate 220 is OLED array base palte, on it, comprise the pel array being formed by OLED210, second substrate 230 is glass substrate, and two substrates surrounding is sealed in OLED array between two substrates after by sealed plastic box 240 envelope frames.In order to make display floater side direction keep good water proof oxygen barrier, in the present embodiment, in described sealed plastic box 240 outsides, be also formed with one deck inorganic material film 250.

In the present embodiment, inorganic material film 250 is the sull of metal-oxide film, silicon or the nitride film of silicon.Because aluminium (Al) has easily oxidized chemical characteristic, and Al ₂o ₃have fabulous water proof oxygen barrier, preferably, metal-oxide film is Al ₂o ₃film.

Further, in order to arrive water proof oxygen barrier better, can form multilayer inorganic material film in sealed plastic box 240 outsides.As shown in Figure 3, sealed plastic box 240 outsides are formed with two-layer inorganic material film: the first inorganic material film 260 and the second inorganic material film 270, the first inorganic material films 260 that form in its outside and the second inorganic material film 270 can be respectively in the sull of metal-oxide film, silicon or the nitride film of silicon different materials form.

The sealed plastic box outside of the display floater of the present embodiment is formed with inorganic material film, and inorganic material film itself has better water proof oxygen barrier, therefore makes display floater side direction have better water proof oxygen barrier.

Because inorganic material film is much better than sealed plastic box with respect to sealed plastic box water proof oxygen barrier under same thickness, therefore, the width of sealed plastic box can reduce greatly, is guaranteeing that frame glue width can allow upper and lower plates glass can reach under the condition of enough bonding strengths, and width preferably can be no more than 1mm.The thickness of inorganic material film can be as thin as below 10 μ m.Therefore, the width sum of the width of sealed plastic box of the present utility model and inorganic material film is also much smaller than the width of existing sealed plastic box, thereby in the situation that keeping good water proof oxygen barrier, reduces the border width of display floater, realizes narrow frame display floater.

As shown in Figure 2, the width sum W1 of the width of its sealed plastic box 240 and inorganic material film 250 is also much smaller than the width of existing sealed plastic box, as shown in Figure 3, the width sum W2 of the width of its sealed plastic box 240, the first inorganic material film 260 and the second inorganic material film 270 is also much smaller than the width of existing sealed plastic box.

The utility model also provides a kind of display floater manufacture method, comprises and makes first substrate, second substrate, and described first substrate and second substrate are sealed to the step of frame by sealed plastic box, and the outside that is also included in described sealed plastic box after envelope frame forms inorganic material film.Inorganic material film is the single thin film one of in the sull of metal-oxide film, silicon and the nitride film of silicon; Or be the plural layers of at least two kinds in the sull of metal-oxide film, silicon and the nitride film of silicon.

In the present embodiment, the step that forms inorganic material film in the outside of sealed plastic box can adopt atomic layer deposition method (ALD) at the outside of sealed plastic box deposition inorganic material film.Due to Al ₂o ₃can adopt easily ALD to make, therefore to form Al ₂o ₃film is example, first the packaged display floater of sealed plastic box is inserted in ald chamber chamber, passes into respectively trimethyl aluminium (tri-methyl aluminum, TMA), and the reactants such as water carry out ALD film-forming process, successively carry out atomic layer and are piled into Al ₂o ₃film.Plural layers, can deposit Al if ₂o ₃after film, then pass into other reacting gas, for example: deposition ZrO ₂(pass into ZrCl ₄and water).

In the present embodiment, the step that forms inorganic material film in the outside of sealed plastic box can also adopt chemical vapour deposition technique (CVD) at the outside of sealed plastic box deposition inorganic material film.To form SiN _xfilm is example, first the packaged display floater of sealed plastic box is inserted and in CVD chamber, passes into respectively SiH ₄, NH ₃deng reactant, carry out CVD film-forming process, to form SiN _xfilm.Plural layers, can deposit SiN if _xafterwards, then pass into other reacting gas, for example, deposit SiON _x(pass into SiH ₄and N ₂o).

Owing to being outside (sealed plastic box is usually located in the gap of display floater side) film forming in sealed plastic box, ALD side direction film forming relatively and CVD be applicable to go deep into the situation in gap, the present embodiment preferably adopts ALD mode to form inorganic material film.

The utility model also provides a kind of display unit that adopts above-mentioned display floater, and this display unit can be: any product or parts with Presentation Function such as liquid crystal panel, Electronic Paper, oled panel, mobile phone, panel computer, television set, display, notebook computer, DPF, navigator.

Above execution mode is only for illustrating the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that not departing from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
