Description

A kind of illumination OLED

Technical field

The utility model relates to a kind of illumination OLED.

Background technology

OLED (Organic Light Emitting Diode Organic Light Emitting Diode) is the organic electroluminescent technology, it is by being clipped in luminous organic material between transparent anode and the metallic reflection negative electrode, organic film is applied voltage to carry out luminous, the OLED luminous efficiency is high, green energy conservation, be a kind of rare planar light source, so OLED has become a kind of trend in the application of lighting field.

Because occured easily by water, oxygen attack deteriorated for organic material, so illumination OLED product must encapsulate with the erosion to organic material of exclusion of water, oxygen.General method for packing is to adopt UV glue ultra-violet curing at present, can reach reasonable packaging effect.

But OLED is in order to improve brightness uniformity in illumination, generally can adopt auxiliary electrode to reduce the interior resistance difference of light-emitting area, especially at the periphery of illumination oled panel, adopts wider auxiliary electrode to lie around and can reach better effect.

Present illumination OLED structure as shown in Figure 1, mainly include packaging line 1, auxiliary electrode 2, light-emitting area 3, negative electrode 4 and anode 5, wherein the rectangle of 1 one-tenth sealing of packaging line is around OLED light-emitting area 3, auxiliary electrode 2 is to reduce impedance contrast, the left and right sides of light-emitting area 3 is negative electrodes 4 of illumination OLED, and both sides are anodes 5 of illumination OLED up and down.Wherein auxiliary electrode 2 integral body are centered around around the illumination OLED light-emitting area 3, to improve brightness uniformity.

But the problem that the structure of this illumination OLED is brought is, in the OLED packaging process, when needing to adopt UV light irradiation packaging line to encapsulate, because packaging line 1 is arranged in the below of the auxiliary electrode 2 of Fig. 1, and the UV lamp can't penetrate 2 pairs of UV glue of auxiliary electrode and is cured, and therefore can't normally encapsulate.The encapsulation schematic diagram of the illumination OLED that adopts at present as shown in Figure 2, can find that packaging line 1 is fully below auxiliary electrode 2, the top of auxiliary electrode 2 is glass substrates 6, the below is glass cover-plate 7, this structure causes the UV encapsulation normally to carry out so that packaging line 1 can't be accepted the irradiation of UV lamp.

The utility model content

The problem that the utility model solves has proposed a kind of illumination OLED that can normally carry out the UV encapsulation exactly.

The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of illumination OLED, comprise packaging line, auxiliary electrode, light-emitting area and negative electrode, described packaging line becomes the rectangle of sealing around light-emitting area, described auxiliary electrode integral body is centered around around the light-emitting area, described negative electrode is arranged on the left and right sides of light-emitting area and includes the first orthogonal negative electrode packaging line and the second negative electrode packaging line, it is characterized in that, described packaging line comprises the first packaging line and the second packaging line, orthogonal being centered around around the light-emitting area and with the first negative electrode packaging line of described the first packaging line forms the first opening and forms the second opening with the second negative electrode packaging line, orthogonal being centered around around the first packaging line and with the first negative electrode packaging line of described the second packaging line forms the 3rd opening and forms the 4th opening with the second negative electrode packaging line, wherein the first opening and the 3rd opening be respectively in the both sides of the first negative electrode packaging line, and the second opening and the 4th opening are respectively in the both sides of the second negative electrode packaging line.

The beneficial effects of the utility model are, have solved because the existence of auxiliary electrode causes the problem that can't normally encapsulate, and can not affect the brightness uniformity of illumination OLED simultaneously, effectively raise the quality of illumination OLED.

Embodiment

Below in conjunction with accompanying drawing, describe the technical solution of the utility model in detail:

As shown in Figure 1, illumination OLED mainly includes packaging line 1, auxiliary electrode 2, light-emitting area 3, negative electrode 4 and anode 5 at present, wherein the rectangle of 1 one-tenth sealing of packaging line is around OLED light-emitting area 3, auxiliary electrode 2 integral body be centered around illumination OLED light-emitting area 3 around, the left and right sides of light-emitting area 3 is the negative electrode 4 of illumination OLED, and both sides are anodes 5 of illumination OLED up and down.The encapsulation schematic diagram of this structure as shown in Figure 2, below auxiliary electrode 2, the top of auxiliary electrode 2 is glass substrates 6 to packaging line 1 fully, and the below is glass cover-plate 7, this structure causes the UV encapsulation normally to carry out so that packaging line 1 can't be accepted the irradiation of UV lamp.Cause this name of the game to be because auxiliary electrode 2 want whole be centered around illumination OLED around, therefore the existence of auxiliary electrode 2 also must be arranged for electric inside and outside connection in the place that packaging line 1 is arranged, therefore cause packaging line 1 can only be arranged on the below of auxiliary electrode 2.

As shown in Figure 3, illumination OLED described in the utility model, comprise the first packaging line 10, the second packaging line 11, auxiliary electrode 2, light-emitting area 3 negative electrodes 4 and anode 5, wherein, auxiliary electrode 2 integral body are centered around around the light-emitting area 3, negative electrode 4 is arranged on the left and right sides of light-emitting area 3, and include respectively the first orthogonal negative electrode packaging line 41 and the second negative electrode packaging line 42, the first packaging line 10 orthogonal being centered around around the light-emitting area 3 and with the first negative electrode packaging line 41 form the first opening 100 and form the second opening 101 with the second negative electrode packaging line 42, described the second packaging line 11 orthogonal being centered around around the first packaging line 10 and with the first negative electrode packaging line 41 form the 3rd opening 110 and form the 4th opening 111 with the second negative electrode packaging line 42, wherein the first opening 100 and the 3rd opening 110 be respectively in the both sides of the first negative electrode packaging line 41, and the second opening 101 and the 4th opening 111 are respectively in the both sides of the second negative electrode packaging line 42.

Main technical schemes of the present utility model, be by packaging line 1 being improved to two packaging lines, being respectively the first packaging line 10 and the second packaging line 11, and two packaging lines are partly linked together with two negative electrode packaging lines of negative electrode 4 respectively, thereby consist of inside and outside two-layer packaging line.And this programme technical solution the name of the game is, auxiliary electrode 2 can by the opening realization electrical connection from inside to outside of inside and outside two-layer packaging line, therefore needn't arrange auxiliary electrode 2 in the place that packaging line 1 is arranged, thereby realize new encapsulating structure again.

The encapsulating structure figure of illumination described in the utility model OLED does not have auxiliary electrode 2 in the place that packaging line 1 is arranged as shown in Figure 4, so UV light can shine packaging plastic, carries out ultra-violet curing.Can find simultaneously, illumination OLED structure described in the utility model, auxiliary electrode 2 is connected as a whole by four openings, and its electrical connection is unaffected, therefore can not have influence on the brightness uniformity of illumination OLED.
