Abstract
Disclosed is a field-sequential-color display device sequentially driving a plurality of color fields divided from any one frame of a plurality of frames, including: a processor calculating a second field brightness-correction-value of a second color field based on a first field transition-brightness-value transferred from a first color field; and a display unit controlling the second color field based on the second field brightness-correction-value. Correction data is calculated by reflecting a brightness-value transited between color fields in a display to a non-linear brightness-value displayed in the corresponding field to minimize an error caused due to a difference between linear image data and a non-linear brightness-value displayed in the display.
Claims8
A field-sequential-color display device sequentially driving a plurality of color fields divided from any one frame of a plurality of frames, comprising;
- a processor calculating a second field brightness-correction-value of a second color field based on a first field transition-brightness-value transferred from a first color field;
- and
- a display unit controlling the second color field based on the second field brightness-correction-value,
- wherein the processor calculates a second field correction-brightness-value by calculating the first field transition-brightness-value in which a portion of first field brightness-values of the first color field are transferred to a brightness-value of a second color field with a second field brightness-value corresponding to a second field color-value of the second color field, and calculates the second field brightness-correction-value by referring to at least one of the second field brightness-value and the second field correction-brightness-value,
- wherein a predetermined field transition-brightness-value corresponding to a portion of the first field brightness-values of the first color field is transferred to the second field brightness-value of the second color field, and
- the processor calculates the second field correction-brightness-value by using the predetermined field transition-brightness-value.
