WIPO Patent Application WO/2024/098307
Kind Code:
A1
Abstract:
A light conversion unit and a manufacturing method therefor, a display panel, and a pixel unit. The light conversion unit (10) comprises: a light-transmitting flow channel substrate (11), a plurality of light processing structures (12), and an isolation structure (13) arranged between every two adjacent light processing structures (12). The flow channel substrate (11) is provided with a flow channel, and the flow channel is provided with quasi-hemispherical grooves (111) having one-to-one correspondence to the light processing structures (12), and inter-groove flow channels (112) connected in series to the plurality of quasi-hemispherical grooves (111); the light processing structures (12) and the isolation structures (13) are respectively formed in the quasi-hemispherical grooves (111) and the inter-groove flow channels (112); the light processing structures (12) comprise a first light processing structure (121), a second light processing structure (122), and a third light processing structure (123), the three are respectively configured to process incident light of the same wavelength into red light, green light and blue light and then emit same, and the three are connected in series on a same flow channel.
