The local dimming method includes segmenting an input image into N×M (where N and M are positive integer greater than n) blocks; determining representative values of the blocks, which define average luminance of the respective blocks; analyzing the input image; setting a spatial filter mask having a size of n×n (where n is a positive integer greater than 3 and equal to or smaller than 10), increasing the number of coefficients greater than 0 in the spatial filter mask when the input image is determined as a dark image, and decreasing the number of coefficients greater than 0 in the spatial filter mask when the input image is determined as a bright image; and multiplying the block representative values by coefficients of the spatial filter mask to determine a dimming value for each block."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Local dimming method and liquid crystal display","description":"A local dimming method and a liquid crystal display using the same are provided.
