Abstract—Digital displays are fast-growing market comprising LCD, plasma, and rear projection television technologies as well as smaller displays for mobile handsets and automobiles, in addition to many other applications. Digital image processing enhances the overall viewing aesthetics of the displayed image and can differentiate the product. Some display devices have color depth less than the color depth of the input data (for example, eight-bit input data and six-bit display color depth). The input data is either truncated or rounded, but this approach usually produces both a loss of detail and may produce large, banded areas of a single color that differs significantly from the original image. Dithering is used to enhance these images.
Index Terms—LCD (liquid crystal display), FPGA (field-programmable gate array).
