Abstract
The invention relates to one plane sandwich organic electrical light part, which comprises upper and down glass baseboards and several sets of cathode and anode electrodes vertical on baseboard plane in between and several organic layers between cathode and anode, wherein, each cathodes are connected through scan line and each anode connected through signal wire and set with insulation layer between anode and scan line. The invention mainly comprises cathode, anode and organic layer to change structure distribution to remove ITO film.
Description
Technical field
The invention belongs to the flat panel display field, be specifically related to a kind of organic electroluminescence device with plane sandwiched structure.
Background technology
Along with the day by day raising of people to the vision requirement, the Display Technique fast development, day by day, the situation that a hundred flowers blossom, show that from cathode-ray tube display (CRT), liquid crystal display (LCD), plasma (PDP) shows (FED) to ORGANIC ELECTROLUMINESCENCE DISPLAYS (OLED) and electroluminescent, numerous.Science and technology development is maked rapid progress, and the Display Technique field also a revolution is taking place, and various new technology of flat (FPD) are arisen at the historic moment.Cathode-ray tube display (CRT) exists that volume is big, power consumption is high and the shortcoming of radiativity, loses the dominance in demonstration field gradually; And flat panel display is described as a kind of Chaoyang technology, is the main flow of 21st century Display Technique development, thereby has been subjected to people's extensive attention, and it not only will have perfect display quality, and needs at volume, aspect such as energy-conservation more improvement is arranged.LCD, PDP and OLED are three big main flows of flat panel display, wherein OLED with its material extensively, advantage such as rich color, cost of manufacture be cheap, be a kind of big rising flat panel display, be considered to one of present state-of-the-art Display Technique.
The OLED Display Technique, be that a kind of electroluminescence shows, it by anode glass substrate and cathode glass substrate by preparing organic layer betwixt and Vacuum Package is in the same place, powering up on the cathode base of back has electronics to inject, anode has the hole to inject, under electric field action, electronics and the hole formation exciton that in organic layer, meets, exciton is compound and luminous; At present, the subject matter of OLED is the packaged water equality of low, device of life-span, the luminous efficiency of organic material.Wherein, the reason that luminous efficiency is low has following several.Electron injection efficiency is low, has influence on the compound probability with the hole, thereby influences luminous efficiency; Emergent light efficient, because absorption, the scattering of organic layer, effects such as the reflection of ITO layer, waveguide make that emergent light efficient is lower.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of organic electroluminescence device with plane sandwiched structure that can improve the power efficiency and the luminous efficiency of organic electroluminescence device effectively is provided.
For achieving the above object, the technical solution used in the present invention is: comprise top glass substrate, lower glass substrate, be characterized in, between top glass substrate and lower glass substrate, be provided with some groups of negative electrodes and anode perpendicular to the glass substrate plane, be provided with organic layer between negative electrode and the anode, each negative electrode is connected by scan line, and each anode is connected by holding wire, and also is provided with insulating barrier between anode and scan line.
The present invention mainly is made up of negative electrode, anode and organic layer three parts; Owing to changed topology layout, removed the ITO rete, reduced the overall volume of organic layer, can effectively improve the emergent light ratio, improve luminous efficiency.Its another one advantage is exactly to make active driving matrix easily on a side glass substrate.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present invention and operation principle are described in further detail.
Referring to Fig. 1, the present invention includes top glass substrate 6, lower glass substrate 7, between top glass substrate 6 and lower glass substrate 7, be provided with some groups of negative electrodes 3 and anode 4 perpendicular to the glass substrate plane, be provided with organic layer 5 between negative electrode 3 and the anode 4, each negative electrode is connected by scan line 1, each anode is connected by holding wire, and also is provided with insulating barrier 2 between anode 4 and scan line 1.
The present invention links to each other delegation's negative electrode 3 by scan line 1, by holding wire 8 a row anode 4 is linked to each other, if the anode of a sub-pixel 4 is chosen simultaneously with negative electrode 3, then organic layer 5 is excited luminous in this sub-pixel.In traditional structure, parallel with the glass planar successively stack of anode, organic layer, negative electrode, the present invention then are to arrange in vertical glass substrate plane.Negative electrode 3 injects electronics to organic layer 5 under electric field action, anode is injected hole then, organic layer 5 finish electronics and hole transmission, form exciton and produce compound luminously at last, light direction is along the direction of vertical glass substrate.The present invention does not use ito glass, makes organic light emission reduce by a barrier layer in transmission, has reduced absorption, reflection and the scattering etc. of emergent light in organic layer inside simultaneously, thereby improves luminous efficiency.
