Abstract
A liquid crystal display (LCD) has a feed-forward circuit, as a result of which an interference phenomenon occurring in each line of an LCD panel (that is, a color blurring) is prevented, and image quality and life of the LCD panel are enhanced. The LCD comprises a feed-forward circuit for comparing first digital data and second digital data, for generating a correction value based on the comparison, for applying the correction value to the second digital data to obtain corrected digital data, and for outputting the corrected digital data, and a liquid crystal display panel for receiving the corrected digital data, and for displaying an image corresponding to the corrected digital data.
Claims21
A liquid crystal display (LCD), comprising:
- a feed-forward circuit for comparing first digital data and second digital data, for generating a correction value based on the comparison, for applying the correction value to the second digital data to obtain corrected digital data, and for outputting the corrected digital data;
- and
- a liquid crystal display panel for receiving the corrected digital data, and for displaying an image corresponding to the corrected digital data.
A liquid crystal display (LCD), comprising:
- an ON-counter for receiving first digital data and second digital data, and for counting a number of bits represented as one among the first digital data and a number of bits represented as one among the second digital data;
- a memory for storing the number of bits represented as one among the first digital data and the number of bits represented as one among the second digital data;
- an operator for receiving the number ofbits represented as one among the first digital data and the number of bits represented as one among the second digital data, and for generating compensation data by means of operation;
- a level regulator for receiving the compensation data, for operating on the compensation data with a correction coefficient, and for generating a correction value;
- a mixer for operating on the second digital data and the correction value, and for generating corrected digital data;
- and
- a liquid crystal display panel for receiving the corrected digital data, and for displaying an image corresponding to the corrected digital data.
A liquid crystal display (LCD), comprising:
- an OFF-counter for receiving first digital data and second digital data, and for counting a number of bits represented as zero among the first digital data and a number of bits represented as zero among the second digital data;
- a memory for storing the number of bits represented as zero among the first digital data and the number of bits represented as zero among the second digital data;
- an operator for operating on the number of bits represented as zero among the first digital data and the number of bits represented as zero among the second digital data, and for generating compensation data;
- a level regulator for receiving the compensation data, for operating on the compensation data with a correction coefficient, and for generating a correction value;
- a mixer for operating on the second digital data and the correction value, and for generating corrected digital data;
- and
- a liquid crystal display panel for receiving the corrected digital data, and for displaying an image corresponding to the corrected digital data.
