Display apparatus and driving method thereof for enhancing image quality using an encoder and a decoder

摘要

A display apparatus is disclosed. In one aspect the apparatus includes an encoder configured to encode a Nth first image data, where N is an integer of 2 or greater and a (N−1)th second image data at different rates. The display further includes a memory configured to store the encoded Nth first image data and the encoded (N−1)th second image data, a decoder configured to decode the encoded Nth first image data and the encoded (N−1)th second image data received from the memory and, an image processor configured to perform color processing on the decoded Nth first image data. It also includes an image converter configured to convert the Nth first image data received from the image processor into Nth second image data and an image quality enhancer configured to enhance image quality of the Nth second image data based on the decoded (N−1)th second image data.

1. A display apparatus comprising:
an encoder that encodes Nth first image data and (N−1)th second image data at different rates, where N is an integer of 2 and greater; a memory that stores the encoded Nth first image data and the encoded (N−1)th second image data; a decoder that decodes the encoded Nth first image data and the encoded (N−1)th second image data received from the memory; an image processor that performs color processing on the decoded Nth first image data; an image converter that converts the Nth first image data received from the image processor into Nth second image data; an image quality enhancer that enhances image quality of the Nth second image data based on the decoded (N−1)th second image data; and a display panel that displays an image using the Nth second image data from the image quality enhancer.
