Abstract
By controlling light emission, non-emission, and light intensity of each of the light emitting elements arranged on a backlight unit, a point-shaped light emitting point is created and the light emitting point is moved along the arrangement of pixels formed on a liquid crystal display panel unit. By moving the light emitting point as if an electron beam were scanning in the CRT display, it is possible to enhance the dynamic image blur removal effect.
Claims15
A backlight apparatus for providing light for a display panel apparatus which displays an image on a display screen by changing optical transmittance of a plurality of display units arranged on a display substrate, said backlight apparatus comprising:
- a support device;
- a plurality of light emitting elements, disposed on said support device, for producing a luminous point in a backlight area which is disposed behind the display panel apparatus;
- and
- a light emission controlling device for displacing the luminous point continuously in a direction of the adjacent light emitting element in the backlight area by changing light emission and non-emission of each of said light emitting elements or by changing intensities of lights emitted from said plurality of light emitting elements.
A liquid crystal display apparatus comprising:
- a liquid crystal display panel unit for displaying an image on a display screen by changing optical transmittance of a liquid crystal disposed between two display substrates;
- and a backlight unit for providing light for said liquid crystal display panel unit,
- said backlight unit comprising:
- a support device;
- a plurality of light emitting elements, disposed on said support device, for producing a luminous point in a backlight area which is disposed behind said liquid crystal display panel unit;
- and
- a light emission controlling device for displacing the luminous point continuously in a direction of the adjacent light emitting element in the backlight area by changing light emission and non-emission of each of said light emitting elements or by changing intensities of lights emitted from said plurality of light emitting elements.
