Abstract
Provided is a liquid crystal display device wherein blurring of a moving image is effectively suppressed. A liquid crystal display device 1 includes a liquid crystal layer 13 that is arranged on a backlight 10, and includes liquid crystal that is driven in response to a voltage applied thereto; a light detection unit 20 that is arranged between the backlight 10 and the liquid crystal layer 13; and a control unit that controls a timing of turning on the backlight 10. After the backlight 10 is turned off and driving of liquid crystal is started, the control unit turns on the backlight 10 when intensity of light detected by the light detection unit 20 enters a steady state.
Claims5
A liquid crystal display device comprising:
- a backlight;
- a liquid crystal layer that is arranged on the backlight, and includes liquid crystal that is driven in response to a voltage applied thereto;
- a light detection unit that is arranged between the backlight and the liquid crystal layer;
- a control unit that controls a timing of turning on the backlight;
- a light emission unit that emits light having a wavelength that is not perceived by a human but is detected by the light detection unit;
- and
- a reflection unit that reflects light emitted upward by the light emission unit downward,
- wherein, after the backlight is turned off and the driving of liquid crystal is started, the control unit turns on the backlight when intensity of light detected by the light detection unit enters a steady state, and
- the light emission unit is arranged between the light detection unit and the backlight, and the reflection unit is arranged above the liquid crystal layer.
