摘要： The application of microstructures which improve the quality of light available to the viewer of an optical display system, or any display (100) which works on the concept of moving one surface into direct contact or close proximity of a light guide (201, 403, 505, 706, 806, 902, 1201, 1408, 1502) to extract light through frustrated total internal reflection. Optical microstructures are introduced on one or both of the surfaces of the active layer (202, 404, 506, 604, 704, 1501) to enhance its performance.

摘要： A method for addressing a display device comprising applying a data signal to all column electrodes in a set and applying to a first row electrode an ON-select voltage (VrowseloN) such that the pixels connected to said first row electrode can be switched ON by the data signal. Further, an OFF voltage (Vrow,OFF) is applied to at least one second row electrode such that the pixels connected to said second row electrode are switched OFF regardless of the data signal. As a consequence of the inventive method, ON and OFF addressing can be performed during the same scan, and this effect is referred to as 'dual action'. The method according to the invention serves to reduce the dead time in addressing schemes and to decrease the required number of addressing slots.

摘要： A display driving device drives a display which includes a plurality of actuators which control light emitted from specified parts of an optical wave guide plate. A first drive circuit controls the row electrodes, while a second drive circuit controls the column electrodes by outputting a data signal. The data signal includes a light emitting signal and a light extinguishing signal for each dot in the display, based on an input image signal. The column electrode drive circuit controls gradation only by a temporal modulation method. A signal processing circuit, which controls the first and second drive circuits, also controls brightness correction data. Brightness correction data are determined upon manufacture of the display and can be modified during the life of the display to correct for brightness deterioration.

摘要： An optical switching device comprises: a light guide including a total reflection plane capable of totally reflecting light thereby transmitting the light; a switching part capable of, at a position where its extraction plane is in close contact with the total reflection plane, capturing evanescent light and reflecting the captured light thereby outputting it; and a driving part for driving the optical switching part. The light guide, the switching part, and the driving part are laminated in this order into a multilayer structure. The employment of the multilayer structure makes it possible to optimize the respective layers independently of one another. The extracted light does not pass through the driving part. This allows the driving part to be optimized so as to achieve an optical switching device capable of operating at a high speed with low power consumption. Thus, it is possible to provide a low-loss and high-contrast optical switching device using an evanescent wave, which can respond at a high speed.

摘要： A switching TFT (thin-film transistor) 40 is disposed closely to an actuator 14 which comprises a lower electrode 28b, a shape holding layer 26, and an upper electrode 28a that are disposed on a vibrator. The upper electrode 28a of the actuator 14 is electrically connected through a contact 44 to a source/drain region 42 of the TFT 40. A gate line 46 and the gate electrode of the TFT 40 are electrically connected to each other through a contact 50. A data line 48 and a source/drain region 52 of the TFT 40 are electrically connected to each other through a contact 54. The TFT 40 may be replaced with a varistor or a piezoelectric relay. If a varistor is used, the off resistance of the varistor is preferably established such that a variation in a voltage applied to the actuator 14 due to a discharge owing to the off resistance in an unselected period is kept within 5 %, and the on resistance of the varistor is preferably established such that a voltage applied to the actuator 14 increases to 95 % in an effective selected period.
The display apparatus with actuators 14 having shape holding layers has low electric energy consumption and higher raster luminance, and allows wires or interconnections to be formed with ease.
