Display device and driving method for the same

摘要

A display device is disclosed. In one aspect, the display device includes a display panel for displaying an image in at least two separate fields during a frame, a panel driver configured to transmit output data for each field corresponding to the at least two fields and drive the display panel according to each field, and a controller configured to analyze an image pattern corresponding to input data, and generate the output data for each field from the input data according to an analysis result of the pattern, or extract each field data from the input data according to a predetermined data alignment method and generate the output data for each field by using the field data.

1. A display device comprising:
a display panel configured to display an image in at least two separate fields during a frame; a panel driver configured to transmit output data for each field corresponding to the at least two fields to the display panel and drive the display panel according to each field; and a controller configured to:
receive input data, andanalyze an image pattern corresponding to the input data to generate output data for each field based on the input data, according to the analysis result, or generate the output data for each field by using data for each field extracted from the input data according to a predetermined data alignment;wherein the controller comprises a data determiner configured to analyze the image pattern of the input data and output the analysis result,the data determiner comprising:a first counter configured to sequentially read input data of a plurality of odd or even lines and count unit patternsa first comparator configured to compare the count of the first counter with a first threshold value, and if the count is greater than or equal to the first threshold value, the first comparator is configured to set a first flag bit in accordance with first input data of the corresponding line;a second counter configured to sequentially read input data of a plurality of even or odd lines and count unit patterns;a second comparator that compares the count of the second counter with the first threshold value, and if the count is greater than or equal to the first threshold value, the first comparator is configured to set a second flag bit in accordance with first input data of the corresponding line;a pattern determiner configured to count comparison results between the first flag bit and the second flag bit alternately and consecutively transmitted from the first comparator and the second comparator, and if the count is greater than or equal to a second threshold value, the pattern determiner is configured to determine that the pattern is an abnormal pattern.
