Abstract: A high dynamic contrast image display method and device based on a partitioned backlight is disclosed. The method includes steps of: S1: obtaining a brightness information of an arbitrary pixel of an image, S2: obtaining a low-frequency illumination signal of the arbitrary pixel by gaussian filtering, S3: according to a space division of a partitioned backlight, diving the low-frequency illumination signals as same M*N partitions, S4: for anyone of the M*N partitions, calculating a maximum value of the low-frequency illumination signals of a current partition, and S5: performing a linear compression to the low-frequency illumination signal in the current partition. In the invention, the low-frequency illumination signals are subjected to a linear compression according to the luminance range that covered by the actual backlight. Contrast spatial adaptation can be performed within the backlight brightness range, while spatial details corresponding to high-frequency reflected signals are reserved.
