Abstract: An electronic ink screen and a control method therefor and a control device therefor. The control method for the electronic ink screen includes: in a preset time period, ensuring that a difference between the number of times of positive voltage refresh processes corresponding to a target capsule and the number of times of negative voltage refresh processes corresponding to the target capsule is less than or equal to a preset difference threshold. Each of the positive voltage refresh processes includes: increasing an amplitude of a control voltage signal to a preset maximum positive voltage value, and then reducing the amplitude of the control voltage signal. Each of the negative voltage refresh processes includes: reducing the amplitude of the control voltage signal to a preset maximum negative voltage value, and then increasing the amplitude of the control voltage signal.
