Abstract (en)

[origin: EP2099020A2] The present invention discloses a digital electrophoretic display panel driving method and apparatus, the driving device digitally reads a setup value from a memory to eliminate manual adjustment to save labor and to avoid manual adjustment error, and also to reduce a voltage error of a common electrode voltage (Vcom). The digital electrophoretic display panel driving device comprises a panel driving memory disposed on the electrophoretic display panel and coupled with a connecting circuit for a system board to read the data in the panel driving memory via the connecting circuit.
