Embodiment
Now cooperate the description of drawings preferred embodiment.
See also Fig. 1, the organic LED display device 1 of preferred embodiment of the present invention comprises a first substrate 10, an Organic Light Emitting Diode layer 20, one first barrier material 30, a second substrate 40 and one second barrier material 50.
First substrate 10 is a transparent glass substrate, and have one first inner surface 11, the first side 13 and one first outer surface 15, wherein the first inner surface 11 is in contrast to the first outer surface 15, and the first side 13 is linked between the first inner surface 11 and the first outer surface 15.Organic Light Emitting Diode layer 20 is formed at the essence middle section of the first inner surface 11 of first substrate 10.In this embodiment, Organic Light Emitting Diode layer 20 produces white light.In other embodiment, Organic Light Emitting Diode layer 20 can produce the Organic Light Emitting Diode layer that redness, blueness and green primitive color light maybe can produce other colors.Because Organic Light Emitting Diode layer 20 of the present invention is the well known elements of this area, and the non-content of emphasizing for the present invention, is not given unnecessary details at this.
The first barrier material 30 is coated the first inner surface 11 of first substrate 10 and around the periphery of Organic Light Emitting Diode layer 20.In this embodiment, the first barrier material 30 is a photoresists material (UV glue), and this is that a kind of stick needs irradiating ultraviolet light to make its curing.
Second substrate 40 comprises a colored filter 42, and have one second inner surface 41, the second side 43 and one second outer surface 45, wherein the second inner surface 41 is in contrast to the second outer surface 45, and the second side 43 is linked between the second inner surface 41 and the second outer surface 45.The second inner surface 41 of second substrate 40 is towards the first inner surface 11 of first substrate 10 and be linked to the first barrier material 30, Organic Light Emitting Diode layer 20 is arranged in the middle of first substrate 10, the first barrier material 30 and 40 common spaces that form of second substrate whereby, and the first barrier material 30 is to be surrounded by OLED layer 20 around ground.It should be noted that between first substrate 10 and the second substrate 40 not contact fully that the space S of about 2～10 μ m is formed between first substrate 10 and the second substrate 40.In another embodiment, when Organic Light Emitting Diode produced white light, second substrate also can only for plain glass (not shown) need not colored filter, be looked closely the demand of design.In another embodiment, when Organic Light Emitting Diode produced three primary colors or other color of light, second substrate can only be plain glass (not shown), and need not to add colored filter.
The second barrier material 50 is arranged at the outermost of organic LED display device 1, enters space S in order to stop extraneous oxygen and aqueous vapor.In details of the words, the second barrier material 50 is a glass cement, coats the first side 13 of first substrate 10 and the second side 43 and the space S of covering between the first side 13 and the second side 43 of second substrate 40.Before the second barrier material 50 solidified, part the second barrier material 50 may flow in the middle of the S of space, and contacts with the second inner surface 41 with the first inner surface 11.Yet, should be noted between the first barrier material 30 and the second barrier material 50 to have an interval G, do not link to each other each other.
In this embodiment, the thickness T of the second barrier material 50 is between the 6-10 millimeter.That is the second barrier material 50 is the thickness (more than or equal to 1 μ m, and being less than or equal to 5mm) than the second side 43 outwardly about 1 μ m to 5mm of the first side 13 of first substrate 10 and second substrate 40.On the other hand, the height H of the second barrier material 50 system is greater than the width of space S, but less than the distance between the second outer surface 45 of the first outer surface 15 of first substrate 10 and second substrate 40.Thus, the second barrier material 50 can cover the outside of space S fully, but unlikely first, second outer surface 15,45 that protrudes from.
The manufacture of the organic LED display device 1 of preferred embodiment of the present invention is described as follows.The manufacture method of organic LED display device 1 comprises: the processing environment 100 that a hypoxemia, low aqueous vapor are provided, and one first motherboard material 10 ' is set in wherein, wherein a plurality of Organic Light Emitting Diode layers 20 are arranged at (Fig. 2 A) on the first motherboard material 10 '; Be coated with the first barrier material 30 in the periphery of each Organic Light Emitting Diode layer 20 (Fig. 2 B); One second motherboard material 40 ' is provided, is arranged at the first motherboard material 10 ' top, wherein the second motherboard material 40 ' is linked to the first motherboard material 10 ' (Fig. 2 C) by the first barrier material 30; In processing environment 100, utilize ultraviolet light (not shown) to solidify the first barrier material 30, the first motherboard material 10 ' is combined with the second motherboard material 40 '; The first motherboard material 10 ', a plurality of Organic Light Emitting Diode layer 20 and the second motherboard material 40 ' are shifted out processing environment 100 and cut, form a plurality of organic LED display devices 1 (2D figure); Be coated with the second barrier material 50 in the lateral surface 13,43 (2E figure) of first substrate 10 and second substrate 40; Utilize laser aid 200 to solidify the second barrier material 50 (2F figure).
It should be noted, although the organic LED display device 1 of above-mentioned manufacture method be by first, second motherboard material 10 ', 40 ' cut and form, be not restricted to this.In another embodiment, also can make separately single light emitting display device 1, that is form an Organic Light Emitting Diode layer 20 on first substrate 10, and see through the first barrier material 30 and link first, second substrates 10,40, the second barrier material 50 is set again in first, second substrate 10, first, second side 13,43 of 40.
The effect that above-mentioned manufacture method produces is described and will be further specified.Shown in Fig. 2 C, because Organic Light Emitting Diode layer 20 had been arranged at before shifting out processing environment 100 by in the middle of first substrate 10, the first barrier material 30 and the second substrate 40 formed confined spaces, so Organic Light Emitting Diode layer 20 can be isolated with oxygen and the aqueous vapor of external environment.On the other hand, shown in 2E figure, because laser aid 200 only needs to process for the second barrier material 50, when on the second substrate 40 during chromatic colour filter 42, colored filter 42 can Yin Gaowen and damage.When second substrate during only for plain glass (not shown) netrual colour filter, can make processing procedure more simple.
Organic LED display device of the present invention successfully reduces water oxygen transmission rate by the first barrier material and the second barrier material isolated extraneous oxygen and aqueous vapor.In addition, because the second barrier material system is arranged at the outermost of organic LED display device, with the production of favourable organic LED display device, and improves it and produce yield.
Although the present invention discloses as above with preferred embodiment; so it is not to limit the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when can doing a little modification and perfect, so protection scope of the present invention is when with being as the criterion that claims were defined.
