Title:
METHOD AND DEVICE FOR USE IN DRIVING ELECTROPHORETIC DISPLAY PANEL, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/029209
Kind Code:
A1
Abstract:
Provided in embodiments of the present disclosure are a method and device for use in driving an electrophoretic display panel, and a display device. The electrophoretic display panel comprises a first electrode layer, a second electrode layer, and charged particles distributed between the first electrode layer and a second electrode layer. In the method for use in driving the electrophoretic display panel, a direct current voltage signal is applied to the first electrode layer so as to allow the charged particles to move to predetermined positions; an alternating current is applied to the first electrode layer so as to allow the charged particles to oscillate; and a data voltage signal is applied to the first electrode layer for display. When the charged particles are oscillated, the motion activity thereof is increased, this allows the charged particles to move with increased precision on the basis of the data voltage signal, thus increasing display precision.
