摘要:
The electrophoretic display panel (1) for displaying a picture and subsequently displaying a subsequent picture has a pixel (2) having an electrophoretic medium (5) having first and second charged particles (6, 7) and an optical state depending on the positions of the particles (6, 7) in the common region (30) of the pixel (2). Furthermore, transition control means are able to control a transition of the first and the second particles (6, 7) being in substantially separated domains of in the common region (30) for displaying the picture to substantially separated domains of the common region (30) for displaying the subsequent picture. For the display panel (1) to be able to have an attainable optical state for displaying the subsequent picture which is unequal to the optical state determined by the mixture of the first and second particles (6, 7), even if the particles (6, 7) have substantially equal electrophoretic mobilities, the transition control means are further able to control the first and the second particles (6, 7) to be in substantially separated domains of the common region (30) during the transition.

An electrophoretic display panel for displaying a picture has a pixel having an electrophorectic medium having first and second charged particles, the first charged particles having a first optical property, the second charged particles having a second optical property different from the first optical property, and an optical state depending on positions of the particles. Furthermore, particle movement apparatus is arranged to enable a picture movement of the first and the second particles to their respective position for displaying the picture, and particles movement decoupling apparatus is arranged to provide unequal abilities of the first and the second particles to move for substantially decoupling the picture movement of the first particles from the picture movement of the second particles.

An autostereoscopic display device comprises a display arrangement such as an emissive display arrangement or an reflective display arrangement, with an array of spaced pixels. A light guiding arrangement has an array of light guide columns, with one column over each display pixel or over a group (such as a column) of pixels. The light guide columns comprise aside wall which tapers outwardly to define a funnel shape with the pixel at the smaller base of the funnel. The funnel provides collimation to reduce cross talk in the display, which is particularly problematic for 3D autostereoscopic displays.

The present invention relates to an electrophoretic display device (1) and a method of controlling gray level transitions in an electrophoretic display device. The idea of the invention is that, in an electrophoretic device where drive signals (Dr) are applied to display device electrodes (5, 5′) to effect movement of the display particles (8, 9), such that the particles correspond to image information to be displayed, a second electric signal (Ne) is applied to the display device electrodes. This second signal is arranged to decrease the ability of the particles to respond to the drive signal. By employing the second signal in accordance with the invention, more distinct optical states can be attained and the accuracy of the states becomes higher. Thus, the optical states are easier to reproduce due to a more well-defined particle control by means of the drive waveform according to the present invention.

A method for forming a sealed cell structure is disclosed. The sealed cell structure comprises first (10) and second (12) substrates that are spaced apart by a plurality of partition walls (14). The partition walls define a plurality of cells (18, 19) between the first and second substrates. At least one of the substrates and the partition walls have a layer (16, 22, 30) of photo-embossing material on them. A latent image is written (112) onto the photo-embossing material, and then the image is developed, thereby causing expansion of the photo-embossing material in the areas (114) according to the pattern of the latent image. The expansion of the photo-embossing material causes the cells to be sealed apart from one another.

摘要:
An electrophoretic display, in which a driving method is employed whereby a sequence of discrete picture potential differences in the form of a driving waveform is supplied for enabling the charged particles (6) of the display to occupy a position for displaying an image, the position being one of a number of positions between the electrodes (3, 4). The driving waveform consists of a sequence of image update signals including a picture potential difference, the image update signals being separated by dwell times, and the method includes the step of generating one or more shaking pulses during the dwell times. Such shaking pulses may be generated immediately after each image update signal or they may comprise regular shaking pulses generated at predetermined intervals along the waveform.
