|1. (WO2018040667) DISPLAY DEVICE|
|Applicants:||BOE TECHNOLOGY GROUP CO., LTD.
A display device comprises: a display panel (1); a collimation film structure (2); a liquid crystal lens structure (3); and an eye-tracking unit for determining a location of a viewer in front of the liquid crystal lens structure (3). The collimation film structure (2) and the liquid crystal lens structure (3) are sequentially arranged at a light-exiting side of the display panel (1). Specifically, the collimation film structure (2) is used to collimate light emitted by the display panel (1) to form collimated light. The liquid crystal lens structure (3) is used to redirect the collimated light toward the location determined by the eye-tracking unit. The invention combines an eye-tracking technique to determine light-emitting directions of respective subpixels in the display panel (1), and concentrates light at a position at which the eyes receive light. The invention effectively increases light utilization efficiency, and reduces power consumption.
