    摘要: A display (200) with aligned optical shutter and backlight cells (239, 289) uses a patterned polymer-dispersed liquid crystal (PDLC) optical shutter material (230) and an electroluminescent (EL) backlight material (280) to provide a low-cost, low-current-drain display having good contrast in both bright-light and low-light conditions. The aligned, patterned optical shutter and backlight layers form pixel “windows” through which images printed on a background can be hidden or revealed. Specifically, a mask layer (250) bears the images and is inserted between the optical shutter and the backlight layers to show information images, cover inactive areas of the display, and cover electrode traces connecting active segments of the display. The display (200) is thin and flexible enough to be integrated with a touchscreen (290).

    摘要: A liquid crystal device (5) is made by providing an LCD sandwich made of two glass substrates (20) with electrodes, spacers (21), and an uncured sealant (22). A gap (26) with a specified internal volume lies between the two glass substrates. A vacuum reservoir (23) having an internal volume substantially larger than the internal volume of the gap is temporarily attached to the LCD sandwich to align the glass substrates and hold them in place. The LCD sandwich and vacuum reservoir are placed into a conformable container or vacuum bag (24). A vacuum is drawn on the bag so that the bag walls contact the LCD sandwich, and the bag is sealed to maintain the vacuum. The assembly is then heated while under vacuum for a time and a temperature sufficient to cause the gap in the LCD sandwich to decrease to a desired final gap and to cure the sealant.

    摘要: A transflective color liquid crystal display (200) with internal rear polarizer (275) has a front polarizer (260), a front substrate (210), a first color filter layer (212), a front transparent electrode (240), a liquid crystal layer (250), a rear transparent electrode (230), a rear polarizer (275), a reflector (235), and a rear substrate (220). The inclusion of an internal rear polarizer (275) results in little optical path difference between a reflective mode and a transmissive mode of the transflective color LCD (200). The internal rear polarizer (275) also results in little parallax, because the internal reflector (235) is very close to an image-forming layer (250). Additionally, a second color filter layer (214) can be added behind the internal reflector (235) to enhance the brightness and color saturation of the transflective color LCD (200) with internal rear polarizer (275) during the transmissive mode.

    摘要: A high pressure sodium vapor lamp comprising an alumina arc tube within an outer glass envelope is provided with a capacitive starting aid in the interenvelope space. The aid comprises a stiff wire which is pressed lengthwise against the side of the arc tube by a bimetal arm swinging in a plane normal to the lamp axis. Preferably the wire has a camber concave towards the arc tube which is flattened out at room temperature. In the event of a reclosure, the camber shortens the hot restart time.

    摘要: A two-way trans-reflective display pixel (100) having two viewable sides (102, 104) is disclosed. The two-way trans-reflective display pixel has a first transparent layer (106), a second transparent layer (108), and light modulating medium (110) sandwiched between them. Both the first and second transparent layers (106, 108) have light reflectors (132, 136) and light absorbers (130, 134), which allow light entering from either viewable sides (102, 104) to partially reflected, partially absorbed, and partially transmitted, allowing an image to be viewable from both viewable sides (102, 104). A two-way trans-reflective display (402) comprising a plurality of two-way trans-reflective display pixels (100) and a transparent light source (412) is also disclosed. The transparent light source (412) provides color light, and enables an image from the two-way trans-reflective display (402) to be viewable in color from both first and second viewable sizes (418, 602).
