Title:
BINOCULAR OPTICAL DISPLAY SYSTEM HAVING MULTIPLEXED LIGHT SOURCE AND FOLDING LIGHT PATH, AND WEARABLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/232677
Kind Code:
A1
Abstract:
A binocular optical display system having a multiplexed light source and a folding light path, and a wearable device. The binocular optical display system having the multiplexed light source and the folding light path comprises a display (60), a light splitting module (50), a first optical module (10), a second optical module (20), a third optical module (30) and a fourth optical module (40). The light splitting module (50) is disposed on an outgoing light path of the display (60). The light splitting module (50) processes incident light from the display (60) to obtain first emergent light (55) and second emergent light (56). The first optical module (10) is disposed on the light path of the first emergent light (55). The second optical module (20) is disposed on the outgoing light path of the first optical module (10). The third optical module (30) is disposed on the light path of the second emergent light (56). The fourth optical module (40) is disposed on the outgoing light path of the third optical module (30). The binocular optical display system having a multiplexed light source and a folding light path that is small in size, has good imaging quality, has no display light leakage and has good sealability is thus formed. The wearable device having the binocular optical display system having a multiplexed light source and a folding light path is easy to wear, has good universality, can serve myopic users, and significantly improves the user's wearing experience.
