Bistable display and driving method thereof

A bistable display, comprising:

• an inner box constituted of a first substrate, a second substrate and a box body surrounding a space between the first substrate and the second substrate, wherein
• a bistable display material is injected into the space, and one or more of a common electrode conductive layer, a pattern conductive layer, and a background conductive layer are respectively formed on the first substrate and/or the second substrate inside the inner box,
• the common electrode conductive layer is led out of the inner box through a common electrode, the pattern conductive layer is led out of the inner box through a pattern electrode, and the background conductive layer is led out of the inner box through a background electrode,
• a common electrode terminal connected with the common electrode;
• and
• a signal electrode terminal connected with the background electrode and/or the patter electrode, wherein
• a driving signal including a pulse of a first voltage higher than a first stable state drive voltage of the display and a pulse of a second voltage lower than the first stable state drive voltage of the display and higher than a second stable state drive voltage of the display is applied between the common electrode terminal and the signal electrode terminal,
• the background electrode, the pattern electrode and the common electrode are connected in series between the signal electrode terminal and the common electrode terminal through a voltage dividing component to form a voltage divider circuit,
• the voltage dividing component is comprised of one or more of an external capacitor, an internal capacitor, a resistor, and a voltage regulator tube,
• when a driving signal is applied between the common electrode terminal and the signal electrode terminal, the driving signal is directly applied to one of the background electrode and the pattern electrode, and the driving signal of a first divided voltage obtained after the voltage division by the voltage divider circuit is applied to the other one of the background electrode and the pattern electrode,
• the value of the voltage dividing component in the voltage divider circuit and/or values of the first voltage and the second voltage are adjusted so that the first divided voltage applied to the other one of the background electrode and the pattern electrode is lower than the first stable state drive voltage of the display and higher than the second stable state drive voltage of the display when the driving signal is the pulse of the first voltage, and the first divided voltage applied to the other one of the background electrode and the pattern electrode is also lower than the first stable state drive voltage of the display and higher than the second stable state drive voltage of the display when the driving signal is the pulse of the second voltage.
