摘要： A drive method is provided for a display device using the movement of charged particles with a pixel area, with each pixel having first and second drive electrodes (20,23; 22) and a pixel electrode (26). The method comprises a reset phase to move the particles in each pixel towards the first drive electrode (20,23), a pixel data loading phase, to cause selected particles either to stay in the vicinity of the first drive electrode (20,23) or move towards the pixel electrode (26), and a drive phase to distribute the particles which have moved towards the pixel electrode over the pixel electrode (26). The address phase is line-by-line but can be made short, and the other phases can be carried out in parallel for all pixels, saving time.

摘要： A method of reducing visible flicker in a transflective display device, having a plurality of pixels, each pixel comprising a transmissive sub-pixel and a reflective sub-pixel, is disclosed. The method comprises the steps of: driving the pixels with an alternating voltage; determining a first desired compensation voltage for the transmissive sub-pixels and a second desired compensation voltage for the reflective sub-pixels; deriving a common compensation voltage from said first desired compensation voltage and said second desired compensation voltage; and applying said common compensation voltage to both the transmissive and the reflective sub-pixels. Thus, the flicker resulting from a DC bias of the driving voltage is substantially reduced. In a preferred embodiment, the method further comprises the steps of: determining a lowest available frame frequency setting for which any remaining flicker is invisible; and setting a frame frequency at which the display is driven to said lowest available frame frequency. According to another embodiment, a backlight is manually controlled and the common compensation voltage is derived as a function of a mode of operation of the backlight. A transflective display device implementing the above methods is also disclosed.

摘要： An electrophoretic display device comprises an array of rows and columns of display pixels. Each pixel comprises first and second row electrodes (12a, 12b) and first and second column electrodes (14a, 14b). Each row and column electrode has a branch (12a', 12b', 14a', 14b') so that four overlaps are defined between an electrode and an electrode branch. Between each of the four branch/electrode overlaps, a respective particle reservoir (40a,40b,40c,40d) is located, the respective branch/electrode pair being for controlling movement of particles associated with the respective particle reservoir (40a,40b,40c,40d). This provides a display design which can be implemented as a passive matrix, requiring only two column electrodes and two row electrodes per pixel with four particles.

摘要： A photosensitive electrophoretic display comprises pixels with an electrophoretic material (EF), and a photoconductor (PH) with a first side directed towards the electrophoretic material (EF). The pixels further comprises a first electrode (REl) and a second electrode (RE2) which both are transparent and which both are arranged at a second side of the photoconductor (PH) opposing the first side. In this construction, the photoconductor (PH) if not illuminated acts as a insulator and the electrical field in the electrophoretical material is defined by a voltage difference between the first electrode (REl) and the second electrode (RE2). If the photoconductor (PH) is illuminated, it acts as a conductor with a voltage level which is substantially the average of the voltage levels on the first electrode (REl) and the second electrode (RE2). Thus, dependent on whether the photoconductor (PH) is illuminated or not, different electrical fields occur in the electrophoretical material. These different fields are used to obtain different optical states of the pixels.

摘要： In-plane switching type colour electrophoretic display. The electrophoretic layer consists of cavities (18ab) containing a suspension, which define the pixels (10, 12). Adjacent to each cavity, two control electrodes (20a, 20b) are arranged outside the field of view (26) of the pixel, to initiate in-plane motion of the particles. Two particle types (24a, 24b) differing in colour (yellow, cyan) and optionally: (i) particle mobility or threshold electrical field for initiating motion as well as (possibly charge polarity) or (ii) an additional control electrode also arranged outside the field of view, are arranged in a suspension in the pixel cell. This 'arrangement allows a composite colour scheme for each pixel to be obtained ^in a controllable way. The control electrodes may be arranged at the bounding ends of the cavity, i.e. normal to the layer plane, or in the layer plane at the edges of the cavity. Since they are also covered by a light shielding layer, the electrodes and the particles collected on them, do not impinge on the field of view of the pixel. In addition only a small part of the cavity area is covered by electrode material, so that the total transmission (brightness) of the pixel can be optimized. Two such cells (18ab, 18cd) may be stacked on top of each other. Particles in the second cell (yellow, cyan) have different colours than those in first cell (magenta, black), but their other properties are arranged according to option (i). One of the cells determines mainly the luminance of the display, the other its colour. A white reflector allows a reflective CMY or CMYK subtractive colour display to be achieved. A transmissive variant with a backlight is also disclosed.
