摘要： An electro-optical switch, which can be switched between a substantially transparent state and a scattering state on basis of respective applied voltages, is disclosed. The electro-optical switch has a reflection-voltage curve that is steep enough to allow multiplexing. The electro-optical switch comprises: a scattering layer (302) comprising a liquid crystal-polymer composite; and a reflective layer (306) for reflecting a portion of scattered light back towards the scattering layer (302).

摘要： A lookup table provides voltage waveforms for transitions between a plurality of discrete pixel states forming a set that can be ordered in consecutive states according to a reflectivity of the pixel. An image controller repeatedly executes, in a consecutive drive phase, the steps of retrieving an initial state and update state, matching, when the initial and update states are different, in the ordered set of pixel states of the lookup table, a consecutive state and a corresponding consecutive waveform, the consecutive state forming a path, according to the consecutive drive phase, from the initial state to the update state in the set of pixel states, storing the consecutive state in the memory as new initial state; and controlling a voltage driver to drive the pixel from the initial state to the consecutive state using said consecutive waveform.

摘要： A display driving arrangement is described wherein, during a scan line driving phase, a column driver is controlled to provide a plurality of driving column voltages to the source terminals and the row driver is controlled to provide scanning row selection voltages to the gate terminals for sequentially updating the each pixel having an initial pixel state, voltages with said plurality of driving column voltages to attain, for each initial pixel state, an initial common pixel state. During a common driving phase the column driver is controlled to provide a uniform column voltage to the source terminals to update the plurality of pixel voltages with a uniform column voltage. In addition, the row driver is controlled to provide row select voltages with a gate swing that is lower during the common driving phase than during the row driving phase so as to drive the pixels from a respective the initial common state to a respective final common state. The pixel states may differ from each other at least during a part of the common driving phase or even during the entire common driving phase, so that initial and final common states and intermediate states may differ from pixel to pixel.

摘要： Display units (1) comprising pixels arranged in rows and columns coupled via transistors (12) to row (41, 45, 49) and column (31, 32, 39) electrodes show a relatively large gradient in the image. By introducing means (30, 40) for reducing a voltage difference resulting from a voltage jump on a predefined line, which voltage jump arrives via a capacitance (13, 14), this gradient is reduced. The capacitance (13, 14) may comprise a storage capacitor (13), with the predefined line being a storage line (25). The capacitance (13, 14) may also comprise a parasitic capacitor (14) of the transistor (12), with the predefined line corresponding with the row electrode (41, 45, 49) in the same row. The means (30, 40) comprise line driving circuitry (40) and data driving circuitry (30) for supplying a data signal to pixels (11). The means (30, 40) may also comprise line driving circuitry (40) for driving at a reduced amplitude and may comprise storage line driving circuitry for driving the storage line (25).

摘要： A device for multiple row addressing is driven by frame addressing with pulse patterns based on sets of orthogonal functions. By choosing redundant frames with suitable frame lengths, a less varying frequency content is obtained than with pulse patterns obtained via frames based on a set of binary functions.
