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.
