摘要： One cell of a dual particle lateral movement display (100) uses an lectrophoretic medium comprising a gas (106) containing black particles (108) capable of being tribo-electrically charged to a positive polarity and white particles 110 capable of being tribo-electrically charged to a negative polarity. The display (100) further comprises a rear substrate (116) carrying a pixel electrode (114) covered by a colored dielectric layer (1 24), a transparent front substrate (120) provided with a continuous transparent front electrode (112) and a transparent front protective sheet (128) which provides mechanical protection to the front electrode (112). Side walls (122) extend between the front and rear substrates (120) and (116) and define the microcells within which the gas (106) and the particles (108) and (110) are confined.

摘要： A thin-film transistor (200) includes a gate electrode (206A, 206B) having a first gate electrode edge and a second gate electrode edge opposite the first gate electrode edge. The TFT also includes a drain electrode (212) having a first drain electrode edge that overlaps the first gate electrode edge, and a second drain electrode edge that overlaps the second gate electrode edge. A method for fabricating a diode array for use in a display includes deposition of a conductive layer adjacent to a substrate, deposition of a doped semiconductor layer adjacent to the substrate, and deposition of an undoped semiconductor layer adjacent to the substrate. A display pixel unit provides reduced capacitative coupling between a pixel electrode and a source line. The unit includes a transistor, the pixel electrode, and the source line. The source line includes an extension that provides a source for the transistor. A patterned conductive portion is disposed adjacent to the source line. Another display pixel unit provides reduced pixel electrode voltage shifts. The unit includes a transistor, a pixel electrode, a source line and a balance line. The invention also provides a driver for driving a display provided with such a balance line.

摘要： A thin-film transistor array comprises at least first and second transistors. Each transistor comprises a source electrode, a drain electrode, a semiconductor electrode, a gate electrode, and a semiconductor layer. The semiconductor layer is continuous between the first and second transistors. The semiconductor layer is preferably unpatterned. In various display applications, the geometry of the transistors is selected to provide acceptable leakage currents. In a preferred embodiment, the transistor array is employed in an encapsulated electrophoretic display.

摘要： A method for addressing a bistable electro-optic display having at least one pixel comprises applying an addressing pulse to drive the pixel to a first optical state; leaving the pixel undriven for a period of time, thereby permitting the pixel to assume a second optical state different from the first optical state; and applying to the pixel a refresh pulse which substantially restores the pixel to the first optical state, the refresh pulse being short relative to the addressing pulse.

摘要： An electro-optic display comprises first and second substrates and a lamination adhesive layer and a layer of a solid electro-optic material disposed between the first and second substrates, the lamination adhesive layer having a volume resistivity, measured at 10 °C, which does not change by a factor of more than 3 after being held at 25 °C and 45 per cent relative humidity for 1000 hours. The electro-optic material is preferably an encapsulated electrophoretic material. Other desirable characteristics of lamination adhesives for use in electro-optic displays are also described.

摘要： A cyclic rail-stabilized method of driving an electrophoretic display device (1), wherein a substantially dc-balanced driving waveform is used to effect the various required optical transitions. The driving waveform consists of a plurality of picture potential differences (20), which cause the charged particles (6) of the electrophoretic device (1) to cyclically between extreme optical positions in a single optical path, irrespective of the image sequence required to be displayed, i.e. in order to display each grey scale, it is necessary for the particles (6) to first pass through one of the extreme optical states. In order to minimise the effects of dwell time on the image quality and minimise, or even eliminate, the need to consider image history, shaking pulses (10) are generated immediately prior to each picture potential difference (20).
