Abstract
A Liquid Crystal Display (LCD) assembly and an electronic device is provided in the disclosure. The LCD assembly includes a liquid crystal panel, a resistance detection unit, and a color-temperature-compensation unit. The liquid crystal panel has a first detection point in a first region and a second detection point in a second region. The resistance detection unit is configured to obtain a first resistance value by detecting a resistance value at the first detection point and obtain a second resistance value by detecting a resistance value at the second detection point, and further configured to obtain a resistance difference by calculating a difference between the second resistance value and the first resistance value. The color-temperature-compensation unit is configured to receive the resistance difference, and determine whether Mura appears in a region corresponding to the first detection point in the first region according to the resistance difference.
