Oil motion control is the key for the optical performance of electro-fluidic displays (EFD). In this paper, we introduced an extra pinning structure (EPS) into the EFD pixel to control the oil motion inside for the first time. The pinning structure canbe fabricated together with the pixel wall by a one-step lithography process. The effect of the relative location of the EPS in pixels on the oil motion was studied by a series of optoelectronic measurements. EPS showed good control of oil rupture position. The properly located EPS effectively guided the oil contraction direction, significantly accelerated switching on process, and suppressed oil overflow, without declining in aperture ratio. An asymmetrically designed EPS off the diagonal is recommended. This study provides a novel and facile way for oil motion control within an EFD pixel in both direction and timescale.

Abstract— Interest in the use of electrophoretic displays for smart handheld applications has grown tremendously over the past few years. Since the launch of the Philips and E Ink joint development effort in February 2001, material parameters, TFT backplane, electronic hardware and software and modulization skills have been developed to make this promising display concept into a real product. The first commercial launch of active‐matrix electronic‐ink display modules is planned for mid 2004.

Using an electronic ink display and a touchpanel input device, a paper‐like drawing tablet was created, closely mimicking the behaviour of normal paper. The tablet is initially intended to serve as an input‐device for cartoon drawing and editing. However, its potential use goes far beyond that.

Abstract— With the rise of electrophoretic‐display media from several sources, the world is opening up for new uses of electronic displays. Where “immersive reading” used to be a task strictly reserved for paper, displays can now fulfill that role. Many challenges still remain, such as full‐color photograph‐like performance and video speeds. However, in view of recent accomplishments showing near‐video‐speed switching and potential for full color, after electrophoretic displays obtain a slice of the reading market, application of these developments will take us a significant step towards full‐color animated paper‐like displays. The developments that have led to the presence of electronic paper in the market today will be described, and developments that are about to happen will be discussed.
