A special-shaped display screen includes a carrier, and a plurality of pixel point light sources. The plurality of pixel point light sources are provided on the carrier, each of the pixel point light sources is controllable independently, and at least a portion of the pixel point light sources are arranged in a non-matrix array. A special-shaped pixel light includes a special-shaped display screen, a storage unit, and a main control unit. A control method of a special-shaped pixel light includes the following steps: S1, the main control unit establishing a mapping rule according to orientation characteristics of the pixel point light sources; S2, storing the mapping rule into the storage unit; and S3, receiving a control signal and invoking relevant data in the storage unit to scan the pixel point light sources according to the mapping rule.
