Multiple attaching process, fitting process not only makes process complications, but also there are deviation, bubbles etc. to lack for traditional polarizing film fitting
It falls into, so as to cause a series of optics display problem and package reliability energy is influenced, for example, display panel light-emitting surface can be caused
Multiple attaching process error causes thicknesses of layers different, causes transmitance different.And organic light emitting display face provided by the invention
Plate, dopant material, which is doped in substrate, can guarantee that polarizing film at least has two using polarizing film prepared by light alignment method
The vertical polarized regions of polarization axis direction, so that there are two orthogonal polarization sides for the light tool that goes out of organic light emitting display panel
To even if can be approximately natural light be the display effect that observer can be seen in user wearing polarized glasses, simultaneously as whole face
It is the polarizing film of a polarized regions, i.e., dopant material is aligned by polarization manipulation each along a direction, along same
One direction arranges that extended distance is longer, and dopant material aligns that ability is limited, causes the polarization property of polarizing film poor, causes
There are other direction polarised lights for emergent light, further influence display, it is not only sharp that the light alignment method of use directly prepares polarizing film
The incomplete phenomenon of polarizing film polarization manipulation of having determined effectively is understood in the preparation of the polarizing film (there are multiple polarized regions) of compartmentalization,
And the polarizing film formed through the above way can also effectively avoid being bonded problem and alignment precision, needle in conventional polarizers
To this motion polarizing film, only can reduce technology difficulty by above-mentioned which prevents polarizing film from falling off, and improves polarization
Piece be bonded precision, also can emergent light be approximately natural light be conducive to observer observe.
Compared to traditional organic light emitting display panel, organic light emitting display panel provided by the invention, on the one hand, utilize
Light alignment method manufactures polarizing film, and flexibility is good, and production efficiency, which can be improved, can also realize slimming, also being capable of save the cost simplification
Technique；On the other hand, the defects of polarizing film can be avoided conventional polarizers attaching deviation, bubble is prepared using light alignment method to lead
The optical effect of cause is bad and influences package reliability, and the precision that polarizing film is bonded with display panel can be improved；It is another
Aspect, organic light emitting display panel go out light tool there are two polarization direction, and the compartmentalization of polarizing film is arranged, i.e., each region it is inclined
The bending resistance of organic light emitting display panel can be improved in vibration piece absorption axiss difference；In another aspect, organic light emitting display panel
Go out light tool there are two perpendicular polarization direction, even if can be approximately natural light be that observer can in user wearing polarized glasses
The display effect seen improves user experience.
