Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all 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 application.
Embodiments of the present application provide a display panel and a method of manufacturing the same, which will be described in detail below.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present disclosure. The display panel 100 may include an array substrate 10, a pixel defining layer 20, an encapsulation layer 30, and a
The array substrate 10 may include a plurality of thin film transistors.
Wherein, the pixel defining layer 20 is disposed on the array substrate 10. The pixel defining layer 20 is provided with a plurality of pixel pits 21 distributed in an array. Note that the pixel pit 21 has a first predetermined shape. In some embodiments, the first preset shape may include a circle, an ellipse, or a star.
Wherein the encapsulation layer 30 is disposed on the pixel defining layer 20. This packaging layer 30 not only can keep apart display panel 100 with the external world, has avoided water and oxygen to invade display panel 100, influences display panel 100's life, and packaging layer 30's surface is flat simultaneously for
The
In some embodiments, the pixel pits 21 have a pixel structure 22 therein. As shown in fig. 2 or fig. 4, the pixel structure 22 may include a blue pixel 221, a red pixel 222, or a green pixel 223. It should be noted that the blue pixel 221 and the red pixel 222 may be star-shaped. It should be noted that the sides of the star are curved sides, that is, the star is a curved-side star. The green pixel 223 may be circular or elliptical. It will be appreciated that the shape of the pixel pits 21 is the same as the shape of the pixel structures 22. That is, the blue pixel pits and the red pixel pits may be star-shaped, and the green pixel pits may be circular or elliptical. It is understood that the area of the blue pixel 221 is larger than the area of the red pixel 222 and the area of the green pixel 223, and the area of the red pixel 222 is larger than the area of the green pixel 223.
In the embodiment of the present application, since the blue pixel pit and the red pixel pit are in a radial star shape, the green pixel pit may be in a circular shape or an elliptical shape. The arc-edge star shape, the circular shape or the oval shape can effectively reduce the spreading distance difference of the ink and the difference of the corners and edges of the pixel pits 21 on the ink effect when the pixel structures 22 are formed by the ink-jet printing technology, thereby being beneficial to the uniform spreading of the ink in the pixel pits 21 and improving the light-emitting uniformity of the pixel structures 22. Therefore, when ink is dropped into the pixel pits 21 having the first preset shape by the ink jet printing technique, the ink can be uniformly laid down in the pixel pits to form the pixel structures 21.
In some embodiments, color film structure 42 is in color film pit 41. As shown in fig. 3 or fig. 5, the color film structure 42 may include a
It should be noted that the thickness of the color film structure 42 may be 1 micron to 3 microns. The curing temperature of the color film structure 42 is less than or equal to 100 ℃.
In the embodiment of the present application, the blue color film pit and the red pixel pit are circular, and the green pixel pit may be circular or elliptical. It can be understood that, because there is no corner in the round or oval fillet structure, the spreading distance difference of the ink and the difference of the effect of the corner and the edge of the color film pit 41 on the ink can be effectively reduced when the color film structure 42 is formed by the inkjet printing technology, which is beneficial to the uniform spreading of the ink in the color film pit 41. Therefore, when ink is dropped into the color film pit 41 having the second predetermined shape by the inkjet printing technique, the ink can be uniformly spread in the pixel pit to form the color film structure 42.
It can be understood that the color film structure 42 can filter the emergent light, so as to improve the color purity of the emergent light; on the other hand, the color film structure 42 can filter external light, and can reduce ambient light entering the display panel 100, thereby reducing reflection of the display panel 100 on the ambient light and improving user experience.
It is understood that the blue pixel 221 corresponds to the
In order to avoid the adverse effect on the optical characteristics of the pixel structure 21 after the
In some embodiments, the display panel 100 may further include a pixel electrode 23. The pixel electrode 23 is provided corresponding to the pixel pit 21.
In order to further enable the ink to be uniformly spread when the pixel structure 22 and the color film structure 42 are formed, the film layer uniformity of the pixel structure 22 and the color film structure 42 is improved. In some embodiments, the surface of the pixel defining layer 20 has hydrophobicity, and the surface of the pixel electrode 23 has hydrophilicity. The side wall of the color film pit 41 has hydrophobicity, and the bottom wall of the color film pit 41 has hydrophilicity.
Since the surfaces of the pixel defining layer 20 and the color film pit 41 have hydrophobicity, when ink is dropped on the sidewall of the pixel pit 21 or the sidewall of the color film pit 41, the ink can smoothly slide down onto the pixel electrode 23 or the bottom wall of the color film pit 41. In addition, the bottom walls of the pixel electrode 23 and the color film pit 41 have hydrophilicity. Therefore, a concave liquid surface can be prevented from being formed on the contact surface of the ink and the pixel electrode 23 and the contact surface of the ink and the bottom wall of the color film pit 41, which is beneficial to the uniform spreading of the ink on the pixel electrode 23 and the color film pit 41, and the pixel structure 22 and the color film structure 42 with uniform thickness can be formed.
In some embodiments, the display panel 100 may further include a protective layer 50. The protection layer 50 is disposed on the
From the above, the display panel 100 provided by the embodiment of the present application may include an array substrate 10, a pixel defining layer 20, an encapsulation layer 30, and a

It will be appreciated that the shape of the pixel pits 21 is the same as the shape of the pixel structures 22. That is, the blue pixel pits and the red pixel pits may be star-shaped, and the green pixel pits may be circular or elliptical. It is understood that the area of the blue pixel 221 is larger than the area of the red pixel 222 and the area of the green pixel 223, and the area of the red pixel 222 is larger than the area of the green pixel 223.
