AI Technical Summary
Existing color electrophoresis displays have difficulty precisely controlling the position of multiple pigments within a limited thickness space, resulting in inaccurate color display. Furthermore, traditional driving methods lead to color flickering and long refresh times.
The electrophoretic medium uses four types of particles, two of which carry opposite charges, two of which are subtractive primary colors, and the other is a light-scattering particle. Through an improved driving method, five voltage levels (high positive, low positive, zero, low negative, and high negative) are used to control the particle position, avoiding stepped waveforms and achieving fast refresh and reduced color flicker.
It enables precise control of pigment position within a limited space, reduces color flicker, improves the accuracy and refresh rate of color display, and expands the color range.
