Description

Organic Light Emitting Diode

Technical field

This utility model relates to Organic Light Emitting Diode.

Background technology

Organic Light Emitting Diode (OLED) can select glow color easily by the change of organic material chemical constitution, conventional OLED colorization technology has independent luminescent material method, colored filter film method, color conversion method and microresonator toning method, wherein, color conversion method is the primaries relaying out red, green, blue after the blue light that OLED is sent utilizes dyestuff extinction again, but when resolution increases, the luminescence of each pixel can cause light leak or the situation interfered with each other because of horizontal proliferation in medium, affects luminescent quality.On the other hand, driving voltage is the highest.

Utility model content

For the problems referred to above, this utility model provides Organic Light Emitting Diode, improves its structure, it is to avoid the luminescence of each pixel causes light leak or the situation interfered with each other because of horizontal proliferation in medium, reduces driving voltage simultaneously, improves luminescent quality.

For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, this utility model is achieved through the following technical solutions:

Organic Light Emitting Diode, including MgAg cathode layer from inside to outside, ito anode layer and glass substrate, described It is provided with power supply between MgAg cathode layer and ito anode layer, it is characterized in that, electron transfer layer, blue light-emitting layer and hole transmission layer have been sequentially arranged it between described MgAg cathode layer and ito anode layer, cushion and color changing mediums layer also it has been sequentially arranged between described ito anode layer and glass substrate, described cushion is for having certain thickness insulating material layer, one end of described color changing mediums layer is provided with blue light and turns HONGGUANG module, centre is provided with blue light and turns green module, and described blue light turns the two ends of green module and is separately provided for the dividing plate of isolation.

Preferably, described cushion is layer of lithium fluoride, and thickness is 0.5nm-2nm；Or, stating cushion is silicon dioxide layer, and thickness is 0.5nm-2nm.

The beneficial effects of the utility model are: traditional Organic Light Emitting Diode, light leak or the situation interfered with each other is easily caused between color transition module, the luminescence that can be prevented effectively from each pixel by increasing dividing plate causes light leak or the situation interfered with each other because of horizontal proliferation in medium, improve luminescent quality, meanwhile, cushion improves electric charge injection efficiency, reduces driving voltage.

Detailed description of the invention

Being described in further detail technical solutions of the utility model with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art can be better understood from this utility model and can be practiced, but illustrated embodiment is not as to restriction of the present utility model.

As it is shown in figure 1, Organic Light Emitting Diode, including MgAg cathode layer 1 from inside to outside, ito anode layer 5 and glass substrate 11, described It is provided with power supply between MgAg cathode layer 1 and ito anode layer 5, it is characterized in that, it has been sequentially arranged electron transfer layer 2 between described MgAg cathode layer 1 and ito anode layer 5, blue light-emitting layer 3 and hole transmission layer 4, cushion 12 and color changing mediums layer 6 also it has been sequentially arranged between described ito anode layer 5 and glass substrate 11, described cushion 12 is for having certain thickness insulating material layer, one end of described color changing mediums layer 6 is provided with blue light and turns HONGGUANG module, centre is provided with blue light and turns green module, described blue light turns the two ends of green module and is separately provided for the dividing plate of isolation.

Wherein, described cushion 12 can be layer of lithium fluoride or silicon dioxide layer, and thickness is preferably 0.5nm-2nm.

Preferably, it is B/R colored filter 8 that described blue light turns HONGGUANG module, and it is B/G colored filter 7 that described blue light turns green module.

Three MgAg cathode electrode units that in Fig. 1, MgAg cathode layer 1 includes at equal intervals, is arranged side by side.The both sides of B/G colored filter 7 are respectively symmetrically and are provided with the first dividing plate 9 and second partition 10, and it can be extinction material, it is preferred that reflective material.The outside of described ito anode layer 5 is additionally provided with one layer of thin megohmite insulant as cushion 12, such as layer of lithium fluoride, silicon dioxide layer etc., it is possible to decrease driving voltage.

Traditional Organic Light Emitting Diode, light leak or the situation interfered with each other is easily caused between color transition module, the luminescence that can be prevented effectively from each pixel by increasing dividing plate causes light leak or the situation interfered with each other because of horizontal proliferation in medium, improve luminescent quality, meanwhile, cushion 12 improves electric charge injection efficiency, reduces driving voltage.

These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, is the most in like manner included in scope of patent protection of the present utility model.
