Abstract
A display apparatus and a method for driving display thereof are provided. The display apparatus drives an upper backlight unit and a lower backlight unit so that a first time period during which both the upper backlight unit and the lower backlight unit are simultaneously turned on exceeds half of a second time period during which the upper backlight unit is turned on. Accordingly, the display apparatus may increase a time period during which both the upper backlight unit and the lower backlight unit are simultaneously turned on.
Claims28
A display apparatus comprising:
- a panel which displays input image data;
- an upper backlight unit which irradiates backlight on an upper part of the panel;
- a lower backlight unit which irradiates backlight on a lower part of the panel;
- a timing controller which drives the panel in a first frequency according to an input image signal;
- and
- a backlight driving unit which drives the upper backlight unit and the lower backlight unit based on the first frequency so that a first time period during which both the upper backlight unit and the lower backlight unit are simultaneously turned on exceeds half of a second time period during which the upper backlight unit is turned on,
- wherein the first frequency displays more than two frames in the panel while the upper backlight unit is turned on.
A method for driving display including a panel which displays input image data, an upper backlight unit which irradiates backlight on an upper part of the panel, and a lower backlight unit which irradiates backlight on a lower part of the panel, the method comprising:
- driving the panel in a first frequency according to an input image signal;
- and
- driving the upper backlight unit and the lower backlight unit based on the first frequency so that a first time period during which both the upper backlight unit and the lower backlight unit are simultaneously turned on exceeds half of a second time period during which the upper backlight unit is turned on,
- wherein the first frequency displays more than two frames in the panel while the upper backlight unit is turned on.
A display apparatus comprising:
- a panel which displays input image data;
- a backlight unit which irradiates backlight on the panel;
- a timing controller which drives the panel in 480 Hz according to an input image signal;
- and
- a backlight driving unit which drives the backlight unit based on the 480 Hz so that a time period during which both a portion of the backlight unit and a rest of the backlight unit are simultaneously turned on exceeds half of a time period during which the portion of the backlight unit is turned on,
- wherein the 480 Hz displays more than two frames in the panel while the portion of the backlight unit is turned on.
A method for driving display including a panel which displays input image data, a timing controller which drives the panel, and a backlight unit which irradiates backlight on the panel, the method comprising:
- receiving an input image signal in a first frequency;
- driving the panel in a second frequency according to the input image signal, wherein the second frequency is eight times the first frequency;
- and
- driving the backlight unit based on the second frequency so that a time period during which both a portion of the backlight unit and a rest of the backlight unit are simultaneously turned on exceeds half of a time period during which the portion of the backlight unit is turned on,
- wherein the second frequency displays more than two frames in the panel while the portion of the backlight unit is turned on.
