    摘要: A heavy duty wheeled trailer for use in towing the trailer behind a vehicle. The trailer includes an adjustable height tow connection point to adjust and connect to different types of tow vehicles while maintaining the front deck substantially parallel to the trailer main deck. The trailer further includes a modular support frame allowing the trailer to be easily scaled in length and performance capabilities through removal or addition of modular frame cells.

    摘要: A cholesteric liquid crystal display device (40) comprises a stack of three cells (10), each cell comprising a layer of cholesteric liquid crystal material (19) capable of being switched between a plurality of states including a planar state in which it reflects light with wavelengths in a central band (31) corresponding to red, green and blue, respectively, and in overtone bands (32, 33) on both sides of the central band (31). Each adjacent pair of cells 10 in the stack is held together by a layer of adhesive (42, 43). At least one of the layers of adhesive (42, 43) includes a red dye which is absorbent of light with wavelengths in the overtone bands (32) on the side of the central band (31) of lower wavelength. The red dye improves the perceived red colour of light reflected from the red cell (10R) by suppressing the overtone bands. The provision of the red dye in the adhesive provides several advantages in manufacture.

    摘要: A liquid crystal display device includes at least one cell which provides a rectangular array of addressable pixels having an average area of at least 4 mm2. The cell comprises: two substrates (11, 12) defining therebetween a cavity; a layer of liquid crystal material in the cavity; and a respective conductive layer (13, 14) formed on each of the substrates (11, 12). The conductive layers (13, 14) are patterned to provide a rectangular array of separate drive electrodes (51) each capable of driving an area of the layer of liquid crystal material adjacent the respective drive electrode as one of said pixels. The conductive layers (13, 14) also provide a separate track (33) connected to each of the separate drive electrodes (51) and extending to a position outside the array of addressable pixels where the tracks (33) form terminals (34) each capable of receiving a respective drive signal. This allows direct addressing of the pixels. The relatively large size of the pixels allows such direct drive without an unacceptable reduction in the contrast ratio. In addition, the conductive layers may be patterned in a variety of ways to further improve the contrast ratio, e.g. the second conductive layer (14) is patterned to provide a common electrode (72) and a plurality of separate counter electrodes (76). Each respective counter electrode (76) extends over an area opposite one of the gaps (35) between the lines of the electrodes (51).
