Problems solved by technology

The traditional supporting film material is PET (Polyethylene Terephthalate, polyethylene terephthalate) or CPI (transparent polyimide), and the above materials have anisotropy, which will cause phase delay, and the incident light is different on different interfaces. Optical interference occurs, so if the traditional support film is applied to the OLED display panel of the camera under the screen, rainbow patterns will be generated, and there is an imaging interference problem

Abstract

The invention provides a display panel and a display device, belongs to the technical field of display, and can solve the problem of imaging interference. The display panel comprises a display screen and a first supporting film structure, the first supporting film structure is located on one side of a non-display surface of the display screen, the first supporting film structure comprises a first supporting film layer, and the in-plane phase difference and the thickness direction phase difference of the first supporting film layer are smaller than or equal to a first threshold value, or the in-plane phase difference and the thickness direction phase difference of the first supporting film layer are larger than or equal to a second threshold value, and the first threshold value is smaller than the second threshold value; and the in-plane phase difference Re and the thickness-direction phase difference Rth of the first supporting film layer are designed to be larger values or smaller values, so that when the display panel is a display panel of an under-screen camera, optical interference of visible light wave bands of human eyes can be avoided, poor display such as rainbow lines can be eliminated, and halo interference of imaging can be avoided.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel and a display device. Background technique [0002] Organic Light Emitting Display (OLED) has gradually become the first choice for screens. It has many advantages such as self-illumination, high luminous efficiency, short response time, high definition and contrast, and can also ensure that the screen has certain flexibility and reliability. adaptability. With the development of flexible display screens, people's expectations for foldable display products are getting higher and higher. [0003] At present, flexible display panels generally include structures such as a cover plate, a display screen, and a supporting film. The traditional supporting film material is PET (Polyethylene Terephthalate, polyethylene terephthalate) or CPI (transparent polyimide), and the above materials have anisotropy, which will cause phase delay, and the incident light ...
