With reference to Fig. 1 and Fig. 2, in embodiments of the present invention, display different colours organic light-emitting display device 11,12,13 is
Different organic light-emitting display devices, therefore show that the light emitting layer material of different colours organic light-emitting display device can divide
It is not arranged, uses different light emitting layer materials.
In the prior art, the true color technology of organic light-emitting display device it is general there are two types of, the first is to emit white light
Colored filter is set on public organic luminous layer；Second is setting microcavity resonant structure, and the characteristics of luminescence of microresonator can
Determined by the optical length of microresonator, the light issued from organic luminous layer reflection anode and translucent cathode layer it
Between interfere with each other, cause constructive or destructive interference.Pass through the setting thickness difference in the pixel unit of display different colours
Optical adjustment layer, different optical path lengths is formed between reflection anode and translucent cathode layer, therefore can be to not
Light with color carries out constructive or destructive interference, and then the light of different colours is proposed.But two kinds of true color technologies are used
Shi Douyou technical restriction is shown in the projection virtual image.For example white light collocation colorized optical filtering chip technology, colorized optical filtering sector-meeting seriously reduce
Brightness influences display effect.Microcavity resonant structure is right because the pixel unit of display different colours shares an organic luminous layer
The half-wave wavelength of the material selectional restriction of organic luminous layer, the light of generation is too wide, and display has ghost image, has seriously affected display matter
Amount.
In the present invention, it is not provided with colored filter in the light emission side of organic light-emitting display device, but it is total by microcavity
Vibration structure directly displays colour, improves display brightness；Further, an organic light-emitting display device only shows single kind
Color can targetedly select luminous organic material according to color to be shown, can emit purer color, reduce display
