随着有机发光二极管(Organic Light-Emitting Diode，OLED)技术的发展，人们对OLED显示的要求越来越严格，但OLED仍存在一些制约其发展的问题。以弯折屏为例，由于弯折对不同膜层的力学以及光学性能的影响不同，这会导致弯折区出现色偏现象。With the development of organic light-emitting diode (Organic Light-Emitting Diode, OLED) technology, people have more and more strict requirements on OLED display, but OLED still has some problems restricting its development. Taking the bending screen as an example, since bending has different effects on the mechanical and optical properties of different film layers, this will lead to color shift in the bending area.
本申请提供的显示面板、显示装置及显示面板的制作方法，旨在解决现有技术的如上技术问题。The display panel, the display device and the manufacturing method of the display panel provided by the present application aim to solve the above technical problems in the prior art.
本申请的发明人考虑到，显示面板的弯折区产生色偏的根本原因就是弯折作用使得某一种或几种颜色的光的强度发生改变，例如，色偏颜色为绿色时，就是绿色的光的强度较高所造成的。而纳米粒子由于其小尺寸效应而具有优良的光学特性，纳米粒子的光吸收特性与纳米粒子的尺寸以及材料相关，即不同的材料以及不同的形状和尺寸的纳米粒子，所吸收的光的波长存在着差异。The inventors of the present application consider that the root cause of the color shift in the bending area of the display panel is that the bending effect changes the intensity of light of one or several colors. For example, when the color shift color is green, it is green caused by the higher intensity of the light. Nanoparticles have excellent optical properties due to their small size effect. The light absorption characteristics of nanoparticles are related to the size and material of nanoparticles, that is, the wavelength of light absorbed by different materials and nanoparticles of different shapes and sizes There are differences.
本申请在此基础上，提出了一种利用纳米粒子改善显示面板的弯折区的色偏问题的技术方案，该显示面板具有弯折区，该显示面板包括有机发光显示器件以及位于有机发光显示器件的出光方向上的色偏校正结构，色偏校正结构包括基体和位于弯折区的纳米粒子，纳米粒子位于基体的表面或掺杂在基板的内部。On this basis, the present application proposes a technical solution for improving the color shift problem of the bending area of the display panel by using nanoparticles. The display panel has a bending area. The display panel includes an organic light-emitting display device and a The color shift correction structure in the light emitting direction of the device, the color shift correction structure includes a matrix and nanoparticles located in the bending area, and the nanoparticles are located on the surface of the matrix or doped inside the substrate.
也就是说，本申请通过在弯折区设置纳米粒子，利用纳米粒子对特定波长的光进行吸收来降低该特定波长的光的强度，提出了一种改善显示面板弯折区的色偏问题的新思路。与相关技术中通过优化驱动电路以及通过优化控制信号来改善色偏的方式相比，本申请提出的技术方案不仅能够有效改善显示面板弯折区的色偏问题，而且实施更为简单，在应用时不受有机发光器件的结构以及像素结构的限制，适应性更好。That is to say, the present application proposes a method to improve the color shift problem in the bending area of the display panel by arranging nanoparticles in the bending area and using the nanoparticles to absorb light of a specific wavelength to reduce the intensity of the light of the specific wavelength. new ideas. Compared with the method of optimizing the driving circuit and optimizing the control signal in the related art to improve the color shift, the technical solution proposed in this application can not only effectively improve the color shift problem in the bending area of the display panel, but also is simpler to implement. It is not limited by the structure of the organic light-emitting device and the pixel structure, and has better adaptability.
以上是本发明的核心思想，下面将结合本发明实施例中的附图，以具体地实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。The above is the core idea of the present invention. The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems will be described in detail below with reference to the accompanying drawings in the embodiments of the present invention.
本实施例提供了一种显示面板，如图1和图2所示，该显示面板包括弯折区A，本实施例提供的显示面板包括：This embodiment provides a display panel, as shown in Figure 1 and Figure 2, the display panel includes a bending area A, the display panel provided by this embodiment includes:
有机发光显示基板1；Organic light emitting display substrate 1;
位于有机发光显示基板1的出光方向上的色偏校正结构2，色偏校正结构2包括基体201和位于弯折区A的纳米粒子202，其中，纳米粒子202位于基体201的表面或掺杂在基体201内。The color shift correction structure 2 located in the light emitting direction of the organic light emitting display substrate 1, the color shift correction structure 2 includes a matrix 201 and nanoparticles 202 located in the bending area A, wherein the nanoparticles 202 are located on the surface of the matrix 201 or doped in Inside the matrix 201.
本实施例提供的显示面板，利用纳米粒子202来吸收弯折区A的特定波长的光线，能够改善弯折区A的色偏问题，从而提升显示面板的显示效果；与相关技术中通过优化驱动电路以及通过优化控制信号来改善色偏的方式相比，本实施例提出的显示面板不仅能够有效改善弯折区的色偏问题，而且实施更为简单，在应用时不受有机发光器件的结构以及像素结构的限制，适应性更好。The display panel provided in this embodiment uses nanoparticles 202 to absorb light of a specific wavelength in the bending area A, which can improve the color shift problem in the bending area A, thereby improving the display effect of the display panel; Compared with the method of improving the color shift by optimizing the control signal and the circuit, the display panel proposed in this embodiment can not only effectively improve the color shift problem in the bending area, but also has a simpler implementation and is not affected by the structure of the organic light-emitting device in application. As well as the limitation of the pixel structure, the adaptability is better.
如图1所示，在一些可选的实施例中，弯折区A可以位于显示面板的两端，该种显示面板通常用于制作曲面屏手机等显示装置。如图3所示，在另一些可选的实施例中，显示面板整体为弯折区A，该种显示面板通常用于制作电脑显示器或电视机等显示装置。如图4所示，在又一些可选的实施例中，弯折区A位于显示面板的中部，该种显示面板通常用于制作折叠屏手机等显示装置。As shown in FIG. 1 , in some optional embodiments, the bending area A may be located at both ends of the display panel, and this kind of display panel is usually used to make display devices such as mobile phones with curved screens. As shown in FIG. 3 , in other optional embodiments, the entire display panel is a bending area A, and this kind of display panel is usually used to make display devices such as computer monitors or televisions. As shown in FIG. 4 , in still some optional embodiments, the bending area A is located in the middle of the display panel, and this kind of display panel is usually used to make display devices such as folding screen mobile phones.
需要说明的是，弯折区A位于显示面板的何处并不影响本申请提出的技术方案的实施。为了便于对本申请的技术方案的说明，在下述实施例中，均以“弯折区A位于显示面板的两端”的这一情形为例进行说明。It should be noted that where the bending area A is located on the display panel does not affect the implementation of the technical solution proposed in this application. In order to facilitate the description of the technical solution of the present application, in the following embodiments, the situation that "the bending area A is located at both ends of the display panel" is taken as an example for illustration.
如图2所示，可选地，纳米粒子202为金属纳米粒子、金属氧化物纳米粒子和非金属氧化物纳米粒子中的一种或组合。其中，金属纳米粒子具有良好的线性光学特征，因此，纳米粒子202优选为金属纳米粒子。具体地，金属纳米粒子包括金纳米粒子、银纳米粒子和钛纳米粒子中的一种或组合。在具体实施时，可以根据色偏的情况选用纳米粒子202的材料。As shown in FIG. 2 , optionally, the nanoparticles 202 are one or a combination of metal nanoparticles, metal oxide nanoparticles and non-metal oxide nanoparticles. Among them, metal nanoparticles have good linear optical characteristics, therefore, the nanoparticles 202 are preferably metal nanoparticles. Specifically, the metal nanoparticles include one or a combination of gold nanoparticles, silver nanoparticles and titanium nanoparticles. During specific implementation, the material of the nanoparticles 202 can be selected according to the color shift.
如图2所示，可选地，纳米粒子202为球状纳米粒子、椭球形纳米粒子和棒状纳米粒子中的一种或组合。As shown in FIG. 2 , optionally, the nanoparticles 202 are one or a combination of spherical nanoparticles, ellipsoidal nanoparticles and rod-shaped nanoparticles.
以弯折区A的色偏为黄绿色为例。当色偏为黄绿色时，这是由于绿色光的比例高于标准值所致。因此，为改善色偏情况，应选用可吸收绿色光的纳米粒子202。通过实验得知，在一定范围内，金纳米粒子吸收的光的波长与金纳米粒子的尺寸存在以下关系：Take the color cast of the bending area A as yellow-green as an example. When the color cast is yellow-green, it is due to the proportion of green light being higher than the standard value. Therefore, in order to improve the color shift, nanoparticles 202 capable of absorbing green light should be selected. It is known through experiments that within a certain range, the wavelength of light absorbed by gold nanoparticles has the following relationship with the size of gold nanoparticles:
λ＝514.049+0.3778d(I)λ=514.049+0.3778d(I)
在公式(I)中，λ为金纳米粒子可吸收的光的波长，d为金纳米粒子的直径，其中，λ和d的单位均为纳米。In the formula (I), λ is the wavelength of light that the gold nanoparticles can absorb, and d is the diameter of the gold nanoparticles, where the units of λ and d are both nanometers.
已知地，绿光波长范围是510nm～535nm，因此，通过公式(I)可计算出能够吸收绿光的金纳米粒子的直径范围为0nm＜d≤56nm。将直径范围为0nm＜d≤56nm的金纳米粒子加入弯折区A的色偏校正结构2中，能够对绿光进行一定程度的吸收，使得绿光的强度降低，从而改善弯折区A的黄绿色色偏的问题。It is known that the wavelength range of green light is 510nm-535nm, therefore, the diameter range of gold nanoparticles capable of absorbing green light can be calculated by formula (I) as 0nm<d≤56nm. Adding gold nanoparticles with a diameter range of 0nm<d≤56nm into the color shift correction structure 2 of the bending area A can absorb the green light to a certain extent, reducing the intensity of the green light, thereby improving the color shift of the bending area A. Yellow-green color cast problem.
需要说明的是，色偏也可以为其他颜色，例如色偏为红色或蓝色等。当色偏不同时，需要吸收的光的波长也有所不同。以色偏为红色为例，由于红色光的波长是620nm～760nm，因此需要选择吸收峰在620nm～760nm范围内的纳米粒子202，并根据纳米粒子202的吸收的光的波长与纳米粒子202的尺寸的关系，来选择纳米粒子202的尺寸。当色偏为蓝色时，则选择吸收峰在蓝色光的波长范围内的纳米粒子202，并根据纳米粒子202的吸收的光的波长与纳米粒子202的尺寸的关系，来选择纳米粒子202的尺寸。It should be noted that the color shift may also be other colors, for example, the color shift may be red or blue. When the color shift is different, the wavelength of light that needs to be absorbed is also different. Taking the color shift as red as an example, since the wavelength of red light is 620nm to 760nm, it is necessary to select nanoparticles 202 with absorption peaks in the range of 620nm to 760nm, and according to the wavelength of light absorbed by the nanoparticles 202 and the wavelength of the nanoparticles 202 The size of the nanoparticle 202 is selected in relation to the size. When the color shift is blue, then select the nanoparticle 202 whose absorption peak is in the wavelength range of blue light, and select the nanoparticle 202 according to the relationship between the wavelength of the light absorbed by the nanoparticle 202 and the size of the nanoparticle 202 size.
进一步地，当色偏的严重程度不同时，单位面积上纳米粒子202的数量有所不同，即根据色偏的严重程度调整单位面积上纳米粒子202的数量，从而达到最优的色偏改善效果。Further, when the severity of the color shift is different, the number of nanoparticles 202 per unit area is different, that is, the number of nanoparticles 202 per unit area is adjusted according to the severity of the color shift, so as to achieve the optimal color shift improvement effect .
具体地，如图5所示，显示面板除包括有机发光显示基板1外，还包括在有机发光显示基板1的出光方向上依次排列的薄膜封装结构3、光学胶层4、偏光片5和盖板6。Specifically, as shown in FIG. 5 , in addition to the organic light emitting display substrate 1 , the display panel also includes a thin film encapsulation structure 3 , an optical adhesive layer 4 , a polarizer 5 and a cover arranged in sequence in the light emitting direction of the organic light emitting display substrate 1 . board6.

Specifically, the thin film encapsulation structure 3 generally includes at least two organic layers and an inorganic layer located between the two organic layers, and the thin film encapsulation structure 3 can effectively block the corrosion of the organic light emitting display device by water and oxygen. Reusing the thin film encapsulation structure 3 as the base body 201 of the color shift correction structure 2 can reduce the number of film layers of the display panel and reduce the production cost.
