Description

A kind of light leakage Organic Light Emitting Diode

Technical field

This utility model relates to a kind of light leakage 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.

Utility model content

For the problems referred to above, this utility model provides a kind of light leakage 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, improves luminescent quality.

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

A kind of light leakage Organic Light Emitting Diode, including MgAg cathode layer from inside to outside, ito anode layer and glass substrate, it is provided with power supply between described MgAg cathode layer and ito anode layer, it is characterized in that, it has been sequentially arranged electron transfer layer between described MgAg cathode layer and ito anode layer, blue light-emitting layer and hole transmission layer, it is additionally provided with color changing mediums layer between described ito anode layer and glass substrate, 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, described blue light turns the two ends of green module and is separately provided for the dividing plate of isolation.

Preferably, described blue light turns HONGGUANG module is B/R colored filter.

Preferably, described blue light turns green module is B/G colored filter.

Preferably, three MgAg cathode electrode units that described MgAg cathode layer includes at equal intervals, is arranged side by side.

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, improves luminescent quality.

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 shown in Figure 1, a kind of light leakage Organic Light Emitting Diode, including MgAg cathode layer 1 from inside to outside, ito anode layer 5 and glass substrate 11, it is provided with power supply between described MgAg cathode layer 1 and ito anode layer 5, 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, it is additionally provided with color changing mediums layer 6 between described ito anode layer 5 and glass substrate 11, 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.

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, R light that three MgAg cathode electrode units send with Organic Light Emitting Diode respectively, G light, B light are corresponding.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.

Traditional Organic Light Emitting Diode, easily causes light leak or the situation interfered with each other 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, improves luminescent quality.

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.
