DISPLAY APPARATUS, AND DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR

WIPO Patent Application WO/2023/205966

A1

A display apparatus, and a display panel and a manufacturing method therefor, which relate to the technical field of display. The display panel comprises a driving backplane (BP), a light-emitting layer (OL), a first inorganic layer (CVD1), a lens layer (LL), an organic layer (IJP) and a second inorganic layer (CVD2). The light-emitting layer is arranged on one side of the driving backplane (BP) and comprises a pixel definition layer (PDL) and light-emitting devices (LD), the pixel definition layer (PDL) is provided with openings (PH), and each light-emitting device (LD) is defined in the corresponding opening (PDL). The first inorganic layer (CVD1) covers the light-emitting layer (OL). The lens layer (LL) is arranged on the surface of the first inorganic layer (CVD1) that is away from the driving backplane (BP), and comprises lenses corresponding to the light-emitting devices (LD). The organic layer (IJP) covers the lens layer (LL), and the refractive index of the organic layer (IJP) is less than the refractive index of the first inorganic layer (CVD1), and is less than the refractive index of the lens. The second inorganic layer (CVD2) covers the organic layer. (Figure 8)
