Display device and video viewing system

摘要

A display device includes: a liquid crystal panel including a display surface on which frame images are displayed; a conversion portion for converting a frame image signal into a first image signal representing an image having a lower resolution and a second image signal representing an image having a higher resolution; and a liquid crystal driver for driving the liquid crystal panel with performing first and second scanning operations of the first and second image signals over pixels of the entire display surface. The liquid crystal driver performs the second scanning operation with targeting a drive luminance value which is set in response to an expected value of an achieved luminance value during the first scanning operation for the pixel of the display surface before the second scanning operation commences, and target luminance value for the pixels defined by the frame image signal.

1. A display device comprising:
a liquid crystal panel including a display surface on which frame images are displayed; a conversion portion configured to convert a frame image signal to display the frame image into a first image signal representing an image having a resolution lower than what the frame image signal represents and a second image signal representing an image having a resolution higher than what the first image signal represents; and a liquid crystal driver configured to drive the liquid crystal panel with performing a first scanning operation of the first image signal and a second scanning operation of the second image signal over pixels of the entire display surface, wherein the liquid crystal driver performs the second scanning operation with targeting a drive luminance value, which is determined in response to an expected value of an achieved luminance value during the first scanning operation for the pixel before the second scanning operation commences and a target luminance value defined for the pixel by the frame image signal.
