Abstract
A backlight unit and a liquid crystal display device into which the backlight unit is integrated are provided. The backlight unit includes a first substrate and a second substrate facing each other and spaced apart to provide a discharge space, a plurality of barrier ribs for forming a plurality of discharge cells by partitioning the discharge space, a phosphor layer formed on inner walls of the discharge cells, a first electrode formed on an inner surface of the first substrate and grounded, and a second electrode corresponding to at least one discharge cell.
Claims18
A backlight unit arranged behind a liquid crystal display panel to radiate light, the backlight unit comprising:
- a first substrate and a second substrate facing each other with a discharge space therebetween;
- a plurality of barrier ribs partitioning the discharge space to define a plurality of discharge cells having a stripe shape;
- a phosphor layer arranged on inner walls of the discharge cells;
- a first electrode arranged on a surface of the first substrate that faces the second substrate, the first electrode being grounded;
- and
- a second electrode corresponding to at least one discharge cell and arranged between the second substrate and the phosphor layer.
A liquid crystal display device, comprising:
- a liquid crystal display panel comprising a liquid crystal between a front substrate and a rear substrate;
- and
- a backlight unit to radiate light to the liquid crystal display panel,
- wherein the backlight unit comprises:
- a first substrate and a second substrate facing each other with a discharge space therebetween;
- a plurality of barrier ribs partitioning the discharge space to define a plurality of discharge cells having a stripe shape;
- a phosphor layer arranged on inner walls of the discharge cells;
- a first electrode arranged on a surface of the first substrate that faces the second substrate, the first electrode being grounded;
- and
- a second electrode corresponding to at least one discharge cell and arranged between the second substrate and the phosphor layer, and
- wherein the first substrate is integrated with the liquid crystal display panel.
A method of driving a liquid crystal display device having a liquid crystal display panel comprising a liquid crystal between a front substrate and a rear substrate, and a backlight unit to radiate light to the liquid crystal display panel, the method comprising:
- synchronizing the discharge time of discharge cells of the backlight unit with the scanning time of the corresponding portion of the liquid crystal display panel.
