Abstract: A method of compressing data comprising separating a bit stream of compensation data into a sub-bit stream including an impulse component and a sub-bit stream not including the impulse component, predicting and calculating a trend component of compensation data to be compressed using compressed compensation data, generating a noise component by eliminating the trend component from the compensation data, and separating and compressing an impulse component and a noise component of the compensation data from each other, wherein the impulse component is compressed without quantization and the noise component is quantized and compressed.

Abstract: The present disclosure relates a method for compressing data and a display device using the same, which firstly generates a quantization grid to which a quantization step value is assigned at positions thereon corresponding to positions of the plurality of pixels, assigns the quantization step value using a preset quantization parameter and a quantization function determined according to a dimension of an array, and quantizes data, which is assigned to a pixel located at a position corresponding to a position of the quantization step value, using the quantization step value when the quantization step value is assigned.As such, in accordance with the present disclosure, it may prevent a data loss due to compression of data from being concentrated on pixels located at specific concentrated positions. That is, in accordance with the present disclosure, a data loss due to quantization may be spatially distributed.
