Abstract (en)

[origin: WO2021156548A1] Disclosed is display apparatus (100, 200) comprising pose-tracking means (102, 202); image renderer (104, 106, 204, 206) per eye; liquid-crystal device (108, 110, 208, 210) comprising liquid-crystal structure (114, 116, 214, 216) and control circuit (118, 120, 218, 220); and processor (112, 212). Processor is configured to: process pose-tracking data to determine user's head pose; detect if rate at which head pose is changing is below predefined threshold rate; if yes, switch on lock mode, select head pose for session of lock mode, and generate output image frames according to head pose during session; if no, generate output image frames according to corresponding head poses of user using pose-tracking data; and display output image frames, whilst shifting light emanating from pixels of image renderer to multiple positions (P1-P9) in sequential and repeated manner, said shifting causes resolution of output image frames to appear higher than display resolution of image renderer.
