Abstract
The electronic ink screen capable of dynamic gradual display comprises: an ink capsule layer located between an upper electrode layer and a lower electrode layer; further comprising an upper control electrode and a lower control electrode; the upper control electrode is in electrical signal communication with the upper electrode layer; the lower control electrode is in electrical signal communication with the lower electrode layer. The control module comprises: electrode 1, electrode 2, a voltage conversion module and a control module; electrode 1 and electrode 2 are in electrical signal connection with the voltage conversion module; the control module is in electrical signal connection with the voltage conversion module; the control module outputs a PWM control signal, and the voltage conversion module outputs a voltage signal through the PWM signal. The electrode layer is applied with the PWM control signal through the control electrode; the voltage applied to the electrode layer is controlled through the pulse width of the PWM control signal; the driving of the electronic ink screen capable of dynamic gradual display is realized through the gradual change of the pulse width of the PWM control signal. The structure is simple, the cost is low, and it is particularly suitable for the gradual display of the electronic ink screen signboard.
