Symmetrically arranged power supply reduces device weight while maintaining projection reliability.
Tiled display system uses substrates with lower thermal expansion than attached layers to join panels.
Two projectors and a detector enable simultaneous viewing on both sides, resolving the contradiction between dual-side visibility and device complexity.
A projection device frame uses distinct assembling portions to orient optical and electronic components in different directions.
Proximity detection enables automatic cooperative display across multiple projectors, eliminating manual setup complexity.
A projector suspension device uses a turning member and screw mechanism to adjust rotation and position of the projector.
