Abstract

A wavelength conversion module comprises an isolation structure layer, a plurality of wavelength conversion patterns, a color separation filter film and at least one color separation filter layer. The isolation structure layer has a plurality of openings, and a first surface and a second surface opposite to each other. The plurality of wavelength conversion patterns are respectively arranged in a part of the openings, and are used for absorbing a first part of the plurality of excitation light beams and exciting a plurality of conversion light beams. The color separation filter film is arranged on one side of the first surface of the isolation structure layer. The at least one color separation filter layer is arranged on one side of the second surface of the isolation structure layer or arranged in the openings. Part of the conversion light beams are reflected back to the wavelength conversion patterns through the color separation filter film. The second portion of the excitation light beams passing through the wavelength conversion patterns is reflected back to the wavelength conversion patterns through at least one color separation filter layer. Comprising the wavelength conversion module and a manufacturing method of the wavelength conversion module are also provided. The wavelength conversion module is good in light emitting efficiency.

Description

technical field [0001] The present invention relates to a light-emitting device, an optical module and a manufacturing method thereof, and in particular, to a display device, a wavelength conversion module and a manufacturing method thereof. Background technique [0002] In recent years, under the circumstance that the manufacturing cost of organic light-emitting diode (OLED) display panel is high and its service life cannot compete with the current mainstream displays, Micro LED Display (Micro LED Display) is gradually attracting attention. Investment vision of major technology companies. Micro LED displays have optical performance comparable to OLED display technology, such as high color saturation, fast response speed and high contrast, and have the advantages of low power consumption and long material life. Generally speaking, the manufacturing technology of the micro LED display adopts the method of die transposition to directly transfer the pre-fabricated micro LED di...
