Abstract
A display panel, a manufacturing method thereof, and an electronic device are provided. The panel includes a thickness of a first setting film layer of each of the colored organic light-emitting units of each color is an odd multiple of a half wavelength of the light of the corresponding color, and/or a thickness of a second setting film layer of each of the colored organic light-emitting units is an even multiple of the half wavelength of the light of the corresponding color, wherein the second setting film layer is close to a light-emitting side of the display panel, and the first setting film layer is disposed below the second setting film layer.
Claims15
A display panel, comprising at least one bending region and a non-bending region in a top view, wherein a cross-sectional structure of the display panel comprises:
- a display unit provided on a flexible substrate, wherein the display unit comprises a plurality of colored organic light-emitting units, each of the colored organic light-emitting units of each color is configured to emit light of a corresponding color, and a cross-sectional structure of each of the colored organic light-emitting units comprises:
- an anode, an organic light-emitting layer, a cathode, and an encapsulation layer;
- wherein a thickness of a first setting film layer of each of the colored organic light-emitting units of each color is an odd multiple of a half wavelength of the light of the corresponding color, and a thickness of a second setting film layer of each of the colored organic light-emitting units is an even multiple of the half wavelength of the light of the corresponding color;
- wherein the second setting film layer is close to a light-emitting side of the display panel, and the first setting film layer is disposed below the second setting film layer;
- and
- wherein the thickness of the second setting film layer of each of the colored organic light-emitting units of each color positioned in the non-bending region is an even multiple of the half wavelength of the light of the corresponding color, a compensation film thickness of the second setting film layer of each of the colored organic light-emitting units of each color in the bending region is an even multiple of the half wavelength of the light of the corresponding color, and the compensation film thickness of the second setting film layer is obtained by compensating the thickness of the second setting film layer through a preset included angle, wherein the preset included angle is an included angle between a tangent direction of the bending region and a setting line.
