1. A dark area repair method of a curved liquid crystal display panel, wherein the curved liquid crystal display panel comprises a color filter substrate, an array substrate opposite to the color filter substrate, and a liquid crystal layer disposed between the color filter substrate and the array substrate, the liquid crystal layer comprises a plurality of liquid crystal molecules, and the dark area repair method comprise steps of:
acquiring a preset curvature of the curved liquid crystal display panel, a first pretilt angle of the liquid crystal molecules on a side of the color filter substrate, and a second pretilt angle of the liquid crystal molecules on a side of the array substrate, wherein the first pretilt angle and the second pretilt angle are angles between the liquid crystal molecules and a vertical direction, and the first pretilt angle and the second pretilt angle are different from each other;
obtaining a plurality of sample data of a plurality of sample curved liquid crystal display panels acquired in advance, wherein the sample data comprise sample first pretilt angles, sample second pretilt angles, and sample dark area critical values of the plurality of sample curved liquid crystal display panels;
obtaining a dark area critical value prediction formula using the plurality of sample data, taking the first pretilt angle into the dark area critical value prediction formula to obtain a dark area critical value of the curved liquid crystal display panel;
calculating a difference value between the first pretilt angle and the second pretilt angle; and
determining whether the difference value is greater than or equal to the dark area critical value, and if the difference value is less than the dark area critical value, the difference value is adjusted to be greater than or equal to the dark area critical value to eliminate a dark area to be shown on the curved liquid crystal display panel.
