Abstract

The invention provides an OLED display panel and a display device. According to the OLED display panel, a blind hole is formed between the driving circuit layer and a light-emitting function layer ofthe OLED display panel; a light-transmitting layer is arranged at a position, corresponding to the blind hole, of the flexible substrate; the light-transmitting layer is preferably made of transparentpolyimide; after external light passes through a packaging layer, the external light through the blind hole and the light-transmitting layer, light with the cut-off wavelength ranging from 370 nm to420 nm can normally penetrate, that is, purple light can normally penetrate, a camera assembly below the display screen is be distorted, meanwhile, the average transmittance of light in a camera shooting area is improved, and the camera shooting requirement under a visible light band screen is met.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and a display device. Background technique [0002] Organic light emitting diode (Organic Light Emitting Display, OLED) display panel has many advantages such as self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, near 180° viewing angle, wide operating temperature range, etc. Widely used in smartphones, tablets, full-color TVs, etc. [0003] In order to achieve a full screen, the OLED panel in the prior art uses a hole-digging screen, and a hole for the front camera is set on the display screen, which does not completely solve the 100% screen-to-body ratio. If the front camera is placed behind the display screen , because the average light transmittance in the film structure of the OLED display panel is only 39.2%, and the cut-off wavelength is 416.3nm, which means that the wavelength of pur...
