Abstract
The invention discloses a PM-OLED cathode lead layout structure. The PM-OLED cathode lead layout structure comprises a cathode, a reserved cathode lead and a cathode lead. The cathode is covered with an insulating layer, at least one cathode hole is formed in the insulating layer, one end of the cathode lead is connected with the cathode through the cathode hole, and the other end of the cathode lead is connected with the reserved cathode lead. The invention further discloses a manufacturing method of the layout structure. According to the PM-OLED cathode lead layout structure, the cathode lead and the cathode are of a stacked stereoscopic structure, so that the width of the cathode lead can be increased, and voltage drop on the cathode lead is reduced. Space of the side face of a panel can be further saved, and thus the purpose of design of a narrow frame is achieved.
Description
Technical field
The present invention relates to PM-OLED field, be specifically related to a kind of PM-OLED cathode leg layout structure and manufacture method thereof.
Background technology
OLED technology is regarded as the novel flat-plate Display Technique of development potentiality maximum after LCD, because its outstanding performance advantage has obtained the attention of many countries and enterprise in the world, is at present the stage that technology fast development, industry progressively start; OLED has that active illuminating, fast response time, low-voltage driving, power consumption are low, structure of whole solid state, ultra-thin, visual angle are wide, the plurality of advantages such as can serviceability temperature scope large, has represented the developing direction of current Display Technique.
OLED device is according to the difference of its type of drive, can be divided into passive drive PM-OLED and active driving AM-OLED, passive drive PM-OLED mainly adopts line scanning mode to work, typical PM-OLED is made up of institutes such as glass substrate, ito anode, organic luminous layer and negative electrodes, wherein, ito anode and metallic cathode are clipped in the middle organic luminous layer, and when the hole from anode produces exciton with the electronics from negative electrode in the time that organic luminous layer is combined, exciton is buried in oblivion and sent photon.
The cathode leg of PM-OLED is to draw from negative electrode both sides at present, cathode leg and negative electrode are the structural design that plane is drawn, for frame is unlikely to excessive, it is thinner that cathode leg is designed to be, because cathode leg is thinner, area occupied is fewer, but cathode leg is thinner, resistance will be larger, causes the pressure drop of voltage on cathode leg just higher.
Summary of the invention
The object of the invention is to address the above problem, provide that a kind of stereochemical structure, frame are narrow, low PM-OLED cathode leg layout structure and the manufacture method thereof of lead-in wire pressure drop.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of PM-OLED cathode leg layout structure, comprise negative electrode, reserved cathode leg and cathode leg, on described negative electrode, be coated with insulating barrier, on insulating barrier, corresponding every cathode leg all has a cathode aperture, one end of cathode leg is connected with corresponding negative electrode by cathode aperture, and the other end is connected with corresponding reserved cathode leg.
Preferably, the stepped distribution of described cathode aperture, corresponding one by one with every row negative electrode.
A manufacture method for PM-OLED cathode leg layout structure, is characterized in that comprising the following steps:
Step 1, on negative electrode, generate insulating barrier;
Step 2, make cathode aperture in the position of the corresponding every row negative electrode of insulating barrier;
Step 3, on insulating barrier, make cathode leg, and the two ends of cathode leg are connected with the reserved cathode leg on substrate with negative electrode respectively.
In sum, PM-OLED cathode leg layout structure provided by the present invention is on negative electrode, to be provided with insulating barrier, and cathode leg is drawn by the cathode aperture on insulating barrier, and cathode leg and negative electrode are stacked stereochemical structure, thereby can increase cathode leg width, be reduced in the pressure drop on cathode leg; Can also save panel lateral space, realize the object of narrow frame design.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described further:
As shown in Figure 1, Figure 2 and Figure 3, PM-OLED cathode leg layout structure of the present invention, comprise negative electrode 1, reserved cathode leg 3 and cathode leg 6, on negative electrode 1, be coated with insulating barrier 2, insulating barrier 2 has also covered segment anode lead-in wire 5, on insulating barrier 2, corresponding every cathode leg 6 all has a cathode aperture 4, and the stepped distribution of cathode aperture 4 is corresponding one by one with every row negative electrode 1; Insulating barrier 2 is low-K material, and in the scope allowing in technique, increases the thickness of insulating barrier 2 as far as possible, and thicker low-K material insulating barrier 2 can reduce capacity effect; One end of cathode leg 6 is connected with corresponding negative electrode 1 by cathode aperture 4, and the other end is connected with corresponding reserved cathode leg 3, and cathode leg 6 is stacked stereochemical structure with negative electrode 1, and cathode leg 6 on this basis can be designed to be wider.
When work, electric current flows to negative electrode 1 by reserved cathode leg 3 and cathode leg 6, and the cross section that cathode leg 6 is larger makes the pressure drop on circuit lower, and the energy consumption of product and heating are also less; When PM-OLED production, cathode leg 6 is stacked stereochemical structure with negative electrode 1, can not take the space of negative electrode 1 both sides, makes the frame of product entirety more narrow.
The manufacture method of PM-OLED cathode leg layout structure described in the present embodiment, comprises the following steps:
Step 1, on negative electrode 1, generate insulating barrier 2, insulating barrier has covered most of back side of panel;
Step 2, make cathode aperture 4, the stepped distribution of cathode aperture 4 in the position of the corresponding every row negative electrode 1 of insulating barrier 2;
Step 3, on insulating barrier 2, make cathode leg 6, and the two ends of cathode leg 6 are connected with the reserved cathode leg 3 on substrate with negative electrode 1 respectively.
Those of ordinary skill in the art will appreciate that, embodiment described here is in order to help reader understanding's principle of the present invention, should be understood to that protection scope of the present invention is not limited to such special statement and embodiment.Those of ordinary skill in the art can make various other various concrete distortion and combinations that do not depart from essence of the present invention according to these technology enlightenments disclosed by the invention, and these distortion and combination are still in protection scope of the present invention.
