Problems solved by technology
OLED devices with a color filter structure can reduce power consumption by about 20%. However, after the color filter structure is added to the OLED device, the polarizer is no longer used, but the selective transmission of light and black matrix (BM) to reduce the reflectivity of OLED devices, but CF and BM alone cannot meet the reflectivity requirements of OLED devices, and OLED devices with color film structures are difficult to meet the requirements of lower reflectivity (<5%)

Abstract
The invention discloses a color film structure, a preparation method thereof, and a display device. The color film structure comprises a color film substrate and an anti-reflection layer arranged on the light emitting side of the color film substrate; the color film substrate comprises a color film layer and a black matrix located on the periphery of the color film layer; the anti-reflection layer comprises a first transparent material layer and a second transparent material layer, the refractive index of the first transparent material layer is greater than that of the second transparent material layer, the first transparent material layer at least partially covers the color film layer, and the first transparent material layer is at least partially connected with the second transparent material layer. A first reflection interface is formed at the junction of the first transparent material layer and the second transparent material layer, and the first reflection interface is configured to reflect at least part of light entering the side, away from the color film substrate, of the first transparent material layer to the black matrix.
Description
technical field [0001] Embodiments of the present disclosure relate to, but are not limited to, the field of display technology, and specifically relate to a color filter structure, a manufacturing method thereof, and a display device. Background technique [0002] Organic Light Emitting Diode (OLED for short) and Quantum-dot Light Emitting Diodes (QLED for short) are active light-emitting display devices with self-illumination, wide viewing angle, high contrast, low power consumption, high The advantages of response speed, thinness, bendability and low cost. With the continuous development of display technology, a flexible display device (Flexible Display), which uses OLED or QLED as a light-emitting device and is signal-controlled by a Thin Film Transistor (TFT for short), has become a mainstream product in the display field. [0003] The rapid development of consumer businesses such as mobile phones and tablets has driven the technological update of OLED screens. For OLE...
