Embodiment 1

[0060] see image 3 As shown, the array substrate 100 provided by Embodiment 1 of the present invention includes: at least two layers of transparent film layers 10 stacked in sequence, and among the at least two layers of transparent film layers 10, at least one adjacent two layers of transparent film layers 10 is arranged between There is a light-regulating layer 20, and the product of the refractive index of the light-regulating layer 20 and the thickness of the light-regulating layer 20 is greater than one-half of the preset wave train length.

[0061] When light with a predetermined wavelength enters the above-mentioned array substrate 100, the condition for mutual interference between light with a predetermined wavelength between two adjacent transparent layers is:

[0062] 2ndλ

[0063] Wherein, n in the above formula is the refractive index of the medium layer between two adjacent transparent film layers 10, and d is the thickness of the medium layer between adjacent t...

Embodiment 2

[0091] see Figure 9 As shown, in this embodiment, among two adjacent transparent film layers 10, at least one transparent film layer 10 is provided with a groove 101 on the side close to the other transparent film layer 10, so that between two adjacent transparent film layers 10 An air layer is formed between the transparent film layers 10 , and the air layer is the light adjustment layer 20 . In this embodiment, a groove 101 is arranged in the lower transparent film layer 10, the sidewall of the groove 101 extends along the circumferential edge of the transparent film layer 10, and the top of the groove 101 is in contact with the upper transparent film layer. 10 , the sidewall of the groove 101 and the two adjacent transparent film layers 10 form an air layer, and the air layer is the light adjustment layer 20 .

[0092] see Figure 10 As shown, at least one transparent film layer 10 is provided with a raised pad 102 on the side close to the other transparent film layer 10...

Embodiment 3

[0095] The present invention also provides a display panel, including the array substrate 100 provided in Embodiment 1 or Embodiment 2 above. The following description will be based on the array substrate 100 provided in Embodiment 1. Refer to Figure 11 As shown, the display panel includes an array substrate 100, a light emitting layer 200 disposed on the array substrate 100, and an encapsulation layer 300 disposed on the light emitting layer 200; a light adjustment layer 20 is disposed between the light emitting layer 200 and the encapsulation layer 300, At least one side of the light adjustment layer 20 located between the light-emitting layer 200 and the encapsulation layer 300 is attached to the encapsulation layer 300 and the light-emitting layer 200 .

[0096] For convenience of description and understanding, in this embodiment, the light adjustment layer 20 disposed between the light emitting layer 200 and the encapsulation layer 300 is replaced by the fifth light adjus...

Abstract

The invention provides an array substrate, a display panel and a display device, relates to the technical field of flexible display, and is used for solving the technical problem of the Newton ring phenomenon caused by unequal distances between transparent film layers, which affects the display effect of the display panel. The array substrate comprises at least two transparent film layers which are sequentially arranged in a stacked mode. The light adjusting layer is arranged between at least two adjacent transparent film layers, the product of the refractive index of the light adjusting layerand the thickness of the light adjusting layer is larger than half of the preset wave train length, and the array substrate provided by the invention is used for destroying the forming condition of the Newton ring, eliminating the Newton ring phenomenon and improving the display effect of the display panel.

Description

technical field [0001] The present invention relates to the field of flexible display technology, in particular to an array substrate, a display panel and a display device. Background technique [0002] OLED (Organic Light-Emitting Diode, organic light-emitting diode) display panel has the characteristics of self-illumination, high contrast, thin thickness, fast response speed, wide viewing angle, low power consumption, and flexible display, so it is widely used in the display field . [0003] The display panel includes a plurality of transparent film layers stacked, and blind holes are arranged in at least part of the film layers in the plurality of transparent film layers. Photosensitive elements such as cameras are buried under the display panel corresponding to the blind holes, and external light can pass through The blind holes enter the photosensitive element located under the display panel, which obtains the image. [0004] However, the transparent film layer coveri...
