Circuit (not shown), with the generation for avoiding the reflective of metallic conduction circuit and reducing other problem of appearance.
Fig. 5 is refer to, Fig. 5 is to illustrate a kind of organic LED display device according to an embodiment of the present utility model
500 schematic diagram.Due to the organic LED display device 500 and the organic light emission of earlier figures 1A embodiments of the present embodiment
Diode display 100 is approximate, will only describe difference therebetween below.
As shown in figure 5, organic LED display device 500 includes substrate 115, the film crystal of tool light absorbs function
Pipe array 120, electrical insulation layer 125, flatness layer 130 and luminescence component 190.Wherein, luminescence component 190 includes first electrode layer
150th, organic layer 160 and the second electrode lay 170.For entirety, thin film transistor (TFT) array 120, electrical insulation layer 125, flatness layer
130th, first electrode layer 150, organic layer 160, the second electrode lay 170 and package board 180 are sequentially to be stacked in tool light absorbs function
Substrate 115 on.
The organic LED display device of the organic LED display device 500 compared to Figure 1A of the present embodiment
100 difference is, the structure that the organic LED display device 300 of the present embodiment saves light absorbing layer 140 is set
Meter, but to have the substrate in organic LED display device 100 of the substrate 115 of light absorbs function to replace Figure 1A
110。
In the present embodiment, have the substrate 115 of light absorbs function in making, can be for example and be coated with or increase on a base material
If one layer is made with the film or coating of the phase same material of light absorbing layer 140 of Figure 1A organic LED display device 100
Into, or directly in the production of base material the directly material of the absorbable light of addition is made, not the present embodiment is limited herein
System.Specifically, organic light emission of the optical absorption effect of the substrate 115 of the tool light absorbs function of the present embodiment substantially with Figure 1A
The effect of the light absorbing layer 140 of diode display 100 is identical.Consequently, it is possible to which external light source 111 injects organic light-emitting diodes
Tube display device 300, and can all be absorbed when successively reaching the substrate 115 of tool light absorbs function, without producing reflection, together
Sample can reach the effect for improving the comparison of light and shade in display.
Further illustrate, the electrical insulation layer 125 and flatness layer 130 of the present embodiment are disposed on first electrode layer
Between 150 and thin film transistor (TFT) array 120, and constitute the relation of a composite lamainated structure.The composite lamainated structure is more opened up
There are multiple through holes (figure is not illustrated), and conductive material is filled with through hole, make first electrode layer 150 and thin film transistor (TFT) array
120 are electrically connected with by the conductive material in through hole.
In another embodiment, the organic LED display device 500 of the present embodiment more can further design bag
Chromatic filter layer 175 in organic LED display device 200 containing the embodiment of earlier figures 2.Wherein relevant colored filter
The lamination station and correlation function of photosphere 175 are not just repeated here herein.
From the explanation of above-described embodiment, the utility model be using high-penetration rate and the conductive material of antiradar reflectivity as
First electrode layer and the second electrode lay, then with the reflection of light absorbing layer reduction external light source, reduce addition extra optical diaphragm group
Necessity.Accordingly, Organic Light Emitting Diode can have more preferably self luminous efficiency, and can more mitigate Organic Light Emitting Diode sheet
The thickness and weight of body.In addition, light absorbing layer or the substrate of tool light absorbs function can more provide and block the function that water oxygen is penetrated, when
Consider the overall weight of light emitting display device, thickness, even following bendable application when, light absorbing layer or tool light
The substrate of absorption function can be made up the problem of the sealing effectiveness caused by using plastic substrate is poor, and water oxygen is blocked to be lifted
The ability penetrated, and then improve the life-span of light emitting display device.
Although this case is disclosed above with embodiment, so it is not limited to this case, any to be familiar with this those skilled in the art, not
In the spirit and scope for departing from this case, when can be used for a variety of modifications and variations, therefore this case protection domain when regarding appended power
The scope that sharp claim is defined is defined.
