Black duty insertion mode liquid crystal display for virtual reality

A display device comprising:

• a liquid crystal (LC) panel;
• a back light unit (BLU) configured to emit light;
• and
• a data driver configured to write data to the LC panel,
• wherein the BLU emits light during a portion of a frame period and does not emit light during a remaining portion of the frame period, and
• wherein the data driver writes data to the LC panel during a first portion of the frame period such that liquid crystal material in the LC panel transitions during the portion of the frame period the BLU emits light.

A display device comprising:

• a liquid crystal (LC) panel;
• a data driver configured to write data to the LC panel;
• a back light unit (BLU) configured to emit light;
• and
• a controller coupled to the data driver and the BLU, the controller controlling the data driver to write data to a plurality of rows of the LC panel during a frame period from a frame period start time to a write period end time and instructing the BLU to emit light from an illumination start time to the frame period end time, the illumination start time occurring after the write period end time and at a predetermined timing between the frame period start time and the frame period end time, wherein liquid crystal material in the LC panel transitions after the illumination start time and before the frame period end time.
