In the conventional display panel, a material with high transmittance is required to be used, but the material with high transmittance changes color with time due to the reliability problem, so that the display panel has color cast, and the display effect is influenced. For example, in a display panel, a film layer is formed by using acrylic or Epoxy (Epoxy) materials, which are expensive and have a transmittance that changes with time, thereby greatly increasing the cost of the product and reducing the quality of the product.
Based on this, the embodiment of the application provides a display panel and display device, display panel includes base plate and apron, be provided with the improvement layer between base plate and the apron, the material of improvement layer is coloured macromolecular material, coloured macromolecular material has better reliability, can improve display panel's life like this, coloured macromolecular material is many and not monopolized, therefore the selectivity is many, coloured macromolecular material is low in price, can reduce display panel's cost, and coloured macromolecular material's transmissivity is better, luminous efficiency is high in messenger's display panel, consequently, display panel's colour cast and optical characteristic have been improved.
For a better understanding of the technical solutions and effects of the present application, specific embodiments will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, which is a schematic structural diagram of a display panel provided in an embodiment of the present disclosure, the display panel includes a substrate 10 and a cover plate 30, an improvement layer 20 is disposed between the substrate 10 and the cover plate 30, and a material of the improvement layer 20 is a colored polymer material.
The display panel can include the display area and be located the peripheral non-display area of display area, and the display area has the display function for set up the display element, and the non-display area is not used for showing, can set up circuit unit, walk line isotructure, and circuit unit can include drive circuit, and drive circuit is connected with the display element, is used for controlling the demonstration of display element, thereby makes the display panel show and treats the display content.
In this embodiment, the substrate 10 may be made of glass or Polyimide (PI), and when the substrate 10 is made of Polyimide, the display panel is a Flexible display panel, which is beneficial to implementing new display forms such as various folding screens and curling screens, and the working scenes of the folding screens and curling screens include display in a partially bent state, for example, the display is a flat panel display in a completely unfolded state, and the display in a split-screen and split-function display in a bent state can be implemented.
In the embodiment of the present application, the cover plate 30 may be made of glass or other flexible cover plate 30, and is used for protecting the film layer between the substrate 10 and the cover plate 30. The cover plate 30 is a side of the display panel facing a user, the cover plate 30 has high light transmittance, and an Optical Clear Adhesive (OCA) may be used to adhere the cover plate 30 and the film layer on the substrate 10 in a conventional process.
In the embodiment of the present disclosure, the improvement layer 20 may be disposed between the substrate 10 and the cover plate 30, the material of the improvement layer 20 is an organic Polymer (Polymer) material, and the organic Polymer material has a better reliability and a better Transmittance (Transmittance), so that the optical characteristics of the display panel can be improved. The colored high polymer material has low price, wide selection and favorable selection diversity, simultaneously, the price of the organic high polymer material is greatly reduced compared with that of acrylic and the like, and the cost of the display panel is favorably reduced.
The improved layer 20 may be used to bond the cover plate 30 and the film layer on the substrate 10 instead of the optical adhesive, or may be used to bond different film layers on the substrate 10 together, and still bond the top film layer of the cover plate 10 and the cover plate 30 together by using the optical adhesive.
In the embodiment of the present application, the improvement layer 20 may be doped with improvement particles (particles) 21, and as shown in fig. 2, for a structural schematic diagram of another display panel provided in the embodiment of the present application, the improvement particles 21 are used to improve the Shock resistance (Shock resistance) of the improvement layer 20, so that the improvement layer 20 serves as an Impact Resistance Improvement Layer (IRIL). The modifying particles 21 may have elasticity such that when the modifying layer 20 is impacted, the modifying layer 20 is buffered by slight deformation to protect the underlying film layer. That is, the improvement layer 20 doped with the improvement particles 21 has better impact resistance characteristics than the improvement layer 20 not doped with the improvement particles 21, and the underlying film layer is less likely to be damaged, i.e., damaged to a lesser extent, by the same impact force.
In specific implementation, the modifying particles 21 in the modifying layer 20 may be uniformly distributed or may be non-uniformly distributed. The concentration of the improvement particles 21 can be gradually increased from the center of the improvement layer 20 to the edge, because the collision probability of the edge of the display panel is much greater than that of the middle in daily life, and therefore the higher concentration of the improvement particles 21 is set at the edge of the improvement layer 20, which is beneficial to the targeted damage of the protection screen.
Specifically, the concentration of the improving particles 21 may be increased gradually or may be increased in a certain gradient. Referring to fig. 3, a schematic structural diagram of another display panel in the embodiment of the present application is shown, where the display panel includes a center position 1002 and an edge position 1001, a concentration of the modifying particles 21 at the center position 1002 is less than a concentration of the modifying particles at the edge position 1001, the modifying particles 21 at the center position 1002 may be uniformly distributed or may not be uniformly distributed, and the modifying particles at the edge position 1001 may be uniformly distributed or may not be uniformly distributed.
The display panel is beneficial to displaying in a folding and rolling state and realizing higher light emitting efficiency in the thinning process, but the problem that the thin display panel is easy to damage can be caused, the impact resistance is reduced, the product quality is easy to reduce due to external force, and the consumption feeling of a user is easy to be poor. As can be seen from the formula BS ^ EM × TH (BS: Bending stiff, EM: Elastic Module, TH: Thickness), the thinner the Thickness, the worse the hardness. The addition of the improved layer 20 can protect the core light-emitting structure, improve the overall impact resistance of the display panel, improve the use yield of products, facilitate the thinning of the display panel and improve the product performance.
In the embodiment of the present application, the improvement particles 21 may be blue particles, because the colored polymer material in the improvement layer 20 absorbs light with a specific wavelength, for example, absorbs blue light, which easily results in that the amount of blue light emitted from the improvement layer 20 is small, so that the color change of the colored polymer material caused by the passage of time is yellow, and further the transmittance of the improvement layer 20 is reduced, the blue particles have a scattering effect on the emitted light, and can improve the color shift of the large viewing angle, and can improve the transmittance of blue light, and increase the light emission of blue light, thereby solving the problem of the yellow shift caused by the absorption of blue light by the colored polymer material in the improvement layer 20, and the blue particles can further improve the color shift caused by the passage of time of the film layer in the display panel, balance the problem of the yellow shift of the viewing angle of the film layer, and thereby improve the color shift and the optical characteristics. Specifically, the improving particles 21 may be a polymer resin material.
In specific implementation, the yellowing phenomenon of different degrees from a small viewing angle to a large viewing angle can be balanced under the condition that the concentration of the improvement particles 21 can be gradually increased from the center position to the edge position of the improvement layer 20.
In the embodiment of the present application, the display panel may further include a light emitting layer 11, and the light emitting layer 11 may be disposed between the substrate 10 and the improvement layer 20, or between the improvement layer 20 and the cover 30.

The Light-Emitting layer 11 may include an Organic Light-Emitting Diode (OLED), so that the display panel is an OLED display panel, and the OLED display panel has natural advantages of high color purity, low power consumption, high contrast, and the like, and is suitable for preparing various flexible display devices, and the improvement layer 20 having a high transmittance is favorable for improving the display effect of the OLED display panel, and simultaneously, can also improve the impact resistance of the OLED display panel, and is favorable for realizing the thinning of the OLED display panel.
