Image display techniques for eliminating mura defects, which collects reference data and adjusts the gray levels. The image display systems comprising a plurality of pixels, a memory, and an ASIC. Each of the pixels relates to a mura compensation coefficient set. The mura compensation coefficient sets of the pixels are generated by a coefficient generator. The memory stores the mura compensation coefficient sets of the pixels. The ASIC reads the mura compensation coefficient sets from the memory. With different mura compensation coefficient sets, the ASIC serves as different mura compensation function sets. Each mura compensation function set relates to one of the aforementioned pixels and is used for transforming an original gray level to a mura-eliminated gray level to drive the corresponding pixel.
