Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and fig. 2, the OLED display panel provided in this embodiment includes a substrate base plate 1, a cover plate 2 disposed opposite to the substrate base plate 1, and a frame sealing adhesive 3 located between the substrate base plate 1 and the cover plate 2 and bonding the substrate base plate 1 and the cover plate 2, wherein:
a device layer 4 is arranged on one surface of the substrate base plate 1 facing the cover plate 2, and a filling layer corresponding to an effective display area of the OLED display panel is arranged between the device layer 4 and the cover plate 2;
the gap between the device layer 4 and the cover plate 2 is filled with the filling layer, and the absolute value of the difference between the refractive index of the filling layer and the refractive index of the cover plate 2 is smaller than the absolute value of the difference between the refractive index of the cover plate 2 and the refractive index of nitrogen.
As shown in fig. 3, in the OLED display panel in the prior art, since the shrinkage of the cured frame sealing adhesive 3 needs to be considered, when the frame sealing adhesive 3 is disposed, the thickness of the frame sealing adhesive 3 needs to have a certain margin, and the margin of the thickness of the frame sealing adhesive 3 causes a gap (gap) to exist between the cover plate 2 (e.g., a glass cover plate) and the device layer 4, and the gap is eliminated by the nitrogen layer 7. Such an OLED display panel has problems in that: the rainbow patterns are severe.
The applicant has found that the reason why the rainbow effect of the above-mentioned OLED display panel in the prior art is serious is that: the large difference between the refractive indexes of the nitrogen and the cover plate 2 can cause the reflected light to generate obvious equal inclination interference at the interface of the two layers. As shown in fig. 3, in the case of monochromatic light, the phenomenon of alternating intensity of reflected light occurs; specifically, air has a refractive index of n1Refractive index of glass n2Nitrogen having a refractive index n3When the incident angle of air on the surface of the glass cover plate is theta1Angle of refraction in glass cover plate of alpha1Angle of refraction in nitrogen blanket is beta1Then, according to the law of refraction of light: n is1×sinθ1＝n2×sinα1＝n3×sinβ1If the optical path difference OPD1 between the reflected light generated directly on the surface of the glass cover plate and the light returned to the air after passing through the glass cover plate and the nitrogen gas layer is 2t × cos α1+2d×cosβ1When j λ (j is 0, 1, 2, 3 … …), constructive interference (i.e., bright stripe) appearss); when the incident angle on the surface of the glass cover plate is theta2Angle of refraction in glass cover plate of alpha2Angle of refraction in nitrogen blanket is beta2Then, according to the law of refraction of light: n is1×sinθ2＝n2×sinα2＝n3×sinβ3If the optical path difference OPD1 between the reflected light generated directly on the surface of the glass cover plate and the light returned to the air after passing through the glass cover plate and the nitrogen gas layer is 2t × cos α2+2d×cosβ2When the value is (2j-1) λ/2(j is 0, 1, 2, 3 … …), destructive interference (i.e., dark fringes) appears.
As shown in fig. 4, in the case of polychromatic light, the refractive indexes of lights with different wavelengths in the same medium are different, and the positions of the light intensity distribution after interference are different, resulting in dispersion. Most of the light in the environment is polychromatic light, and the chromatic dispersion and the isocline interference act together to cause serious rainbow fringes.
The OLED display panel provided in this embodiment includes a substrate 1 and a cover plate 2 disposed opposite to the substrate 1, wherein a device layer 4 is disposed on a surface of the substrate 1 facing the cover plate 2, a filling layer corresponding to an effective display area of the OLED display panel is disposed between the device layer 4 and the cover plate 2, and a frame sealing adhesive 3 bonds the substrate 1 and the cover plate 2 (obviously, the frame sealing adhesive 3 is disposed at peripheries of the device layer 4 and the filling layer). The OLED display panel provided in this embodiment fills the gap between the device layer 4 and the cover plate 2 with the filling layer, and the absolute value of the difference between the refractive index of the filling layer and the refractive index of the cover plate 2 is smaller than the absolute value of the difference between the refractive index of the cover plate 2 and the refractive index of nitrogen, that is, the refractive index of the filling layer is closer to the refractive index of the cover plate 2 than the refractive index of nitrogen, so that the isocline interference can be reduced compared with the OLED display panel in which the gap between the cover plate 2 and the device layer 4 is filled with the nitrogen layer 7, thereby improving or even eliminating the rainbow texture problem.
The cover plate 2 may be a glass cover plate, the refractive index of glass is usually 1.53, and the refractive index of nitrogen is close to 1 (actually 1.00029), so that, on the basis of the above embodiment, in an alternative implementation manner, the refractive index of the filling layer may be greater than or equal to 1.4 in order to achieve a better effect of improving the rainbow texture problem.
Further, on the basis of the above embodiment, the refractive index of the filling layer may be 1.6 or less.
Still taking the cover plate 2 as a glass cover plate as an example, when the above-mentioned filling layer is specifically provided, in an alternative implementation, the filling layer includes a glass boss 51 formed on the cover plate 2.
The cover plate 2 is a glass cover plate, the filling layer comprises glass bosses 51 formed on the cover plate 2, and on one hand, the refractive index of the glass bosses 51 is the same as that of the glass cover plate, so that the equal inclination interference can be reduced to the maximum extent, and the rainbow texture problem is improved or even eliminated; on the other hand, the glass boss 51 is formed integrally with the cover plate 2, so that the manufacturing process can be simplified.
As an alternative, the filling layer may also comprise SiO formed on the side of the device layer 4 facing away from the substrate base plate 12 Layer 52.
SiO2The refractive index is 1.47, which is also significantly closer to the refractive index of glass than the refractive index of nitrogen, so that the OLED display panel provided by this embodiment can significantly reduce the isocline interference, and improve or even eliminate the rainbow texture problem compared to the OLED display panel in which the gap between the cover plate 2 and the device layer 4 is filled with a nitrogen layer.
In an alternative implementation, the device layer 4 may include an OLED film layer 42 disposed on the substrate 1, and an electrode layer disposed on the OLED film layer 42, such as: a common electrode layer 41; the side of the cover plate 2 facing away from the filling layer may be provided with a polarizing layer 6(POL) to prevent glare.
Fig. 5 is a simulation effect diagram of an OLED display panel in which a gap between the cover plate 2 and the device layer 4 is filled with a nitrogen layer in the prior art, and fig. 6 is a simulation effect diagram of the OLED display panel provided in this embodiment, which shows that the rainbow patterns of the OLED display panel provided in this embodiment are greatly reduced compared with the rainbow patterns of the OLED display panel in the prior art. Meanwhile, the real shooting with the equivalent verification effect (utilizing the scattering film layer to eliminate the coherence of the light source) can also obviously show that the rainbow texture problem of the OLED display panel provided by the embodiment is greatly improved compared with the rainbow texture problem of the OLED display panel in the prior art.
