摘要:
A method of making an electroluminescent device having a substrate, and at least one dopant receiving layer containing a host material which when doped provides an emissive layer, includes providing at least one dopant layer having a dopant disposed over or under the dopant receiving layer; providing an anode and a cathode so that the dopant receiving layer and the dopant layer are disposed between such anode and cathode; and heating the electroluminescent device to cause the dopant to diffuse from the dopant layer into the dopant receiving layer and forming the emissive layer having uniformly dispersed dopant in the host material.
摘要:
A method and device for manipulating data encoded for introduction to a periodic carrier signal. Distinct disruptions having selected qualities are defined for each character of data. Individual disruption are introduced to individual cycles of the carrier signal. Selected qualities of the disruption used to define the characters of data include the duration of the disruption and the starting time of the disruption relative to the beginning of the cycle. Carrier signals containing the disruptions contain large amounts of information which may be transmitted, stored and manipulated as characters at the level of individual cycles.

A method of producing a color filter array on a transparent support, includes the steps of: forming a polymer image-receiving layer on the transparent support; baking the polymer image-receiving layer on the transparent support so as to harden the polymer image-receiving layer; and imagewise thermally transferring different colorants to form multicolored pixels in the polymer image-receiving layer. The method further includes fixing the colorant pixels into the polymer receiving layer to form the color filter array; and coating the such formed color filter array with an overcoat.

A dual in-band/out-of-band CATV receiver includes a coupler that couples input signals to a tuner and decoder for demodulation and recovery of in-band data and to an FSK receiver for recovery of out-of-band data. The recovered data outputs of the decoder and of the FSK receiver are coupled to a data switch that has a common output that is coupled to a tuner/decoder microprocessor. The tuner/decoder microprocessor in turn supplies information to a switch microprocessor for controlling operation of the data switch to couple either in-band or out-of-band data to the tuner/decoder microprocessor. The data switch defaults to the in-band data position whenever a channel change occurs.

A thermally-transferred color filter array element, preferably for use in a color electro-optical display device such as a color liquid crystal display device, comprising a support having thereon a polymeric dye image-receiving layer containing a thermally-transferred image comprising a repeating pattern of colorants, such as a mosaic pattern, the polymeric dye image-receiving layer having been applied to the support using screen printing.
摘要:
A method for preparing a color filter array element is diclosed which includes the steps of forming an assembly by providing a support on which is coated a polymeric dye image-receiving layer; a stencil pattern on the dye image-receiving layer with holes corresponding to the desired color pixel array pattern; and a dye donor sheet over the stencil. The dye donor has a support film overcoated with a mixture of color dye, polymeric binder, and light absorber. The method further includes exposing the assembly to high intensity light to briefly heat the dye layer and thereby transfer the dye from the donor to the polymeric dye receiving layer so that a colored pattern of pixel elements are formed in or on the image-receiving layer.

A thermal printing system is disclosed in which various patterned masks are used in conjunction with an electronic light flash and other related hardware to thermally transfer dyes to a receiver in such a way as to create a color filter array with an incorporated black matrix for use in a color liquid crystal display device.

An electrochemical resistive ink jet head is disclosed which has the capabilities to vary the color intensity of an coloring agent in an ink, eject the colored ink from the ink jet head, and deposit a colored area on a suitable receiving media.

A method of operating a pay per view (PPV) television system includes transmitting global data packets alternately encrypted with two different session keys. Subscriber terminals store three session keys, and automatically sequence through the session keys in an ateempt to decrypt the data packets. A program tag in the global data packet identifies a television program and a memory location in the subscriber authorization memory and may also include a tag identifying an upcoming program for which the subscriber may self-authorize his terminal by accessing the memory location identified by the PPV tag. The program tag is required to enable the subscriber terminal descrambling means to descramble the accompanying television program. Subscriber terminals are periodically polled by addressed data packets whereupon the contents of their authorization memories are sent to the cable heat-end for billing purposes. After successful polling, a new session key is downloaded to the subscriber in an addressed data packet. After polling of all subscribers, the memory location identified by the PPV tag is cleared by means of a global data packet encrypted in the new session key which only polled subscriber terminals have. An unpolled subscriber terminal needs to be polled before it receives the new session key.
摘要:
A television encoding system passes a modulated video carrier through a pair of SAW filters for attenuating and reversing the phase of the carrier during horizontal intervals. Another pair of SAW filters impart intermediate amplitude and phase changes to the video carrier during transitions into and out of the horizontal intervals to minimize switching transients and frequency disturbances in the color and audio carriers.
