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.

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.

For the electrophoretic display panel (1) to be able to be addressed by passive matrix techniques and to be used in light transmissive mode, the electrophoretic display panel (1) has a magnet (120) for generating a magnetic field, and a pixel (2) having electrodes (10,15) for receiving potentials for generating an electric field, an electrophoretic medium (5) having charged particles (6), the particles (6) having a net magnetic moment and being able to be moved to their position for displaying the picture by a combination of the electric and the magnetic field, an entrance window (92), and an exit window (91) for exiting a portion of transmissable light out of the pixel (2). Furthermore, the transmissable light is capable of having a lightpath from entering the pixel (2) via the entrance window (92), passing through the pixel (2) and exiting out of the pixel (2) via the exit window (91), the portion depending on the position of the particles (6). Furthermore, the magnet (120) is arranged outside the lightpath of at least part of the transmissable light for providing the entrance window (92) to be at least partly distinct from the exit window (91).

A touch-sensitive display is made by incorporating a pressure dependent resistive polymer composite into the polymer networks, which are components of the electro-optical pixels. Examples are PDLC, electrophoretic displays, polymer dispersed guest/host systems and other polymer dispersed LC devices.

A sound and vision system includes a display device (1) and an acoustic transducer, such as a loudspeaker or a microphone. The display device includes display cells (9) having opposite electrodes (7, 8) and includes a conductive line (11) connected to the electrodes in order to address the display cells. The acoustic transducer is formed by the display cell itself and the conductive line is electrically coupled to the display cell/acoustic transducer in order to convey signals, as a result of which the acoustic transducer is an integral part of the display device.

The invention relates to a switching device having shorter switching times. The device comprises a switchable layer (3), which is switched between a reflecting and an absorbing state by changing a hydrogen content of the switchable layer (3). Applying a DC voltage on electroconductive layers (11, 13) changes the hydrogen content. These electroconductive layers (11, 13) sandwich a stack of layers comprising the switchable layer (3) and a hydrogen storage layer (9). The hydrogen storage layer comprises essentially the same compounds as the switchable layer (3), viz. LMgHx and preferably GdMgHx. The storage layer may be made thin, leading to relatively short hydrogen transportation times and a relatively fast display. The device may be further improved by applying a scattering foil.
