In some embodiments, the OLED device disposed in the pixel region is generally a top-emission OLED device, which has an opaque high-reflectivity anode material and also has a certain reflection effect on the ambient light, and the frame region is not provided with the anode, and this structural difference also causes a certain degree of chromatic aberration, so as to weaken the reflection of the anode in the OLED device on the ambient light and further reduce the chromatic aberration between the display region and the frame region in the information shielding state, another display panel is provided, whose cross-sectional structure please refer to fig. 4, which has a substantially similar film structure compared to the display panel provided in the foregoing embodiment, and only includes the following different structural features:
a color resist layer 270 is further disposed on the encapsulation layer 240, and it can be understood that the color resist layer 270 and the black matrix layer 250 are both disposed on the encapsulation layer 240 and, because the color resist layer 270 and the black matrix layer 250 are disposed in different regions, they do not interfere with each other, and the color resist layer 270 and the black matrix layer 250 are completely covered by the transparent flat layer 260, the color resist layer 270 includes a plurality of sub color resists 271 (three are exemplarily shown in the figure) disposed in a plurality of sub pixel regions, where the colors of the plurality of sub color resists 271 correspond to the light emitting colors of the plurality of OLED devices 230a one-to-one, that is, when the OLED device 230a is a red light OLED device, the sub color resist 271 disposed above the OLED device is a red sub color resist, and the other colors are analogized, and according to an actual panel design, the OLED device may generally include red, green, blue, green, or red, green, blue, and white OLED devices.
By providing the color-resist layer 270, the reflection of the anode 231 in the OLED device 230a to the ambient light can be reduced to a great extent, and the specific principle is as follows: each sub-color resistor 271 is used as a color filter film, so that only the ambient light in the corresponding wavelength range is emitted into the display panel, and most of the ambient light is absorbed and filtered, thereby achieving the effect of reducing the reflected light.
In some embodiments, referring to fig. 5, compared to the display panel provided in the previous embodiment, the display panel provided in the previous embodiment has a substantially similar film structure, and only includes the following different structural features:
for the sake of illustration, the transparent planarization layer of this embodiment is defined as a second transparent planarization layer 261, and the second transparent planarization layer 261 is further doped with scattering particles, so that ambient light is incident into the display panel, and when the reflected light of the ambient light from the anode 231 of the OLED device 230a is emitted, a light scattering effect is generated, thereby further improving the display contrast and making the color of the display panel darker black when the display panel is viewed.
Further, since the scattering of light is performed on the premise that the wavelength of light is much larger than the particle size of the scattering particles, i.e., the intensity of the scattering effect is strongly correlated with the particle size of the scattering particles, in some embodiments, the particle size of the scattering particles is set to be less than 1 nm in order to enhance the scattering effect to some extent.
In some embodiments, the scattering particles may be selected from scattering particles conventionally used in the art, but the invention is not limited thereto, and the scattering particles may be, for example, nano silver spheres or nano titanium dioxide spheres.
In some embodiments, in order to further reduce the reflection of the anode 231 of the OLED device 230a to the ambient light, the material of the anode 231 may be modified, and a relatively low-reflectivity anode material is used, specifically, the reflectivity of the anode 231 is 90% to 95%, which is usually greater than 95% compared to the existing conventionally used anode material ITO/Ag/ITO, and is reduced to some extent, so as to further reduce the reflection of the anode 231 in the OLED device 230a to the ambient light, and also further reduce the color difference between the display area and the frame area in the information screen.
Further, the anode 231 is made of aluminum doped with tungsten trioxide and titanium dioxide or tungsten trioxide doped with carbon nanotubes, so that the reflectivity is reduced to a certain degree, and the light extraction efficiency of the OLED device is not lost.
Wherein the preparation of the anode of the above material generally comprises the steps of: preparing the target material of the corresponding material; carrying out physical vapor deposition by using the target material to form a film layer on the whole surface; and then forming the required pattern by exposure etching process.
Further, the applicant has also found that when aluminum doped with tungsten trioxide and titanium dioxide is used as an anode material, the above-mentioned target reflectance can be obtained and the requirement of high light-emitting efficiency can be satisfied when the mass ratio of aluminum, tungsten trioxide and titanium dioxide is controlled to 7 (0.8-1.2) to (1.6-2.4).
In some embodiments, in addition to the above-described structures, other necessary structures are included, specifically referring to the schematic cross-sectional structure of the display panel provided in fig. 6, the display panel further includes a touch layer 280, and it should be noted that the touch layer 280 is usually a capacitive touch layer, and includes metal electrodes formed in the sub-pixel spacing region, which also reflect the ambient light, so that the touch layer is disposed between the encapsulation layer 240 and the black matrix layer 250, so that the black matrix layer 250 on the upper layer can be used to achieve the effect of subtraction;
and the display panel further comprises a cover 290 disposed on the transparent planarization layer 260/the second transparent planarization layer 261.
In some embodiments, in order to further improve the light extraction efficiency of the OLED device 230a, a light coupling-out layer and a light extraction layer (not shown in the figure) are typically sequentially disposed on the cathode 237 in the OLED layer 230, the light coupling-out layer is typically made of a material with a relatively high refractive index, and the light extraction layer is typically made of lithium fluoride.
In the display panel provided in the above embodiment, through a special structural design, the color difference between the display area and the frame area in the screen-refreshing state can be greatly reduced, and a better "black-in-one" effect is achieved, and on the other hand, through the synergistic antireflection action of the black matrix layer, the color resistance layer and the transparent flat layer doped with scattering particles, the circular polarizer structure commonly arranged in the existing OLED display panel can be replaced, so that the thickness of the display panel can be reduced to a certain extent, and the flexibility of the display panel is improved.
It should be noted that, in the embodiment of the display panel provided in the above description, only the above structure is described, and it is understood that, in addition to the above structure, any other necessary structure may be included in the display panel provided in the embodiment of the present invention as needed, and the specific structure is not limited herein.
