High Refractive Index le Optical Performance Optimization

  • SiC's refractive index (2.6-2.7) e batla e phahame ka 50% ho feta ea khalase ea setso (1.8-2.0). Sena se lumella meaho e mesesane le e sebetsang hantle ea waveguide, e holisang FOV haholo. Lenane le phahameng la refractive le boetse le thusa ho hatella "mokotlana" o tloaelehileng ho li-waveguides tse fapaneng, ho ntlafatsa bohloeki ba setšoantšo.

Bokhoni bo ikhethang ba ho laola Thermal

  • Ka mocheso oa mocheso o ka holimo ho 490 W/m·K​​ (haufi le oa koporo), SiC e ka qhala mocheso o hlahisoang ke limojule tsa ponts’o tsa Micro-LED. Sena se thibela ho senyeha ha ts'ebetso kapa ho tsofala ha lisebelisoa ka lebaka la mocheso o phahameng, ho netefatsa bophelo bo bolelele ba betri le botsitso bo phahameng.
