Sequential Compression Using Efficient LUT Correlation for Display Defect Compensation

Abstract

In this paper, we propose a novel sequential compression method for the coefficient look-up table (LUT) for compensation of display panel defects. First, the regression LUT coefficient data for defect compensation is rearranged as the display ratio. It is split and compressed into sub-blocks to utilize the correlation of the rearranged data. Then, to further increase the compression ratio, the initially compressed data is compressed again through the differential coding-based compression. In the performance evaluation, the proposed method has the same loss as the existing compression method, while increasing the compression ratio of up to 46.9%.
