Abstract

The invention provides an OLED display panel and a preparation method thereof. Each pixel opening area is provided with a first micro lens and a second micro lens; the first micro lens is positioned in the pixel opening area, is exposed of and seals the pixel opening area; the second micro lens and the first micro lens are arranged in an aligned manner; the second micro lens covers the first microlens and the pixel opening area; wherein a first planarization layer is arranged between the first micro lens and the second micro lens, a second planarization layer is arranged on the surface of thesecond micro lens, and the refractive index of the first micro lens is smaller than that of the first planarization layer, so that the first micro lens enables the visual angle of emergent light to be narrowed, and more light is emitted to the second micro lens; the refractive index of the second micro lens is greater than that of the second planarization layer, and the emission angle of the emergent light of the second micro lens is increased, so that the display visual angle of the OLED is enlarged, and the double-layer micro lens can improve the light extraction rate of the OLED display panel and improve the display visual angle.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and a preparation method thereof. Background technique [0002] Compared with liquid crystal displays, organic light emitting diode (Organic Light Emitting Display, OLED) display panels have high contrast, wide color gamut, viewing angle, response speed of moving images, etc., so they are more and more used in smart phones. With the expansion of the application field of OLED display panels on smart phones, higher requirements are put forward for the display quality, such as larger display viewing angle and lower power consumption. [0003] Since the light emitted from the bottom of the pixel groove in the OLED display panel is output through the encapsulation layer, cover layer, etc., the output light has a specific directionality, and most of the light is emitted vertically from the screen, resulting in OLED display panel The display viewing angle of the ...
