Definitions

  • Dense circuit matrices typically contain row and column addressed integrated circuits. Addressing locations on dense circuit matrices are applicable to many different devices. For example, dense circuit matrices are often implemented in flat panel displays, charge-coupled devices (CCDs) such as digital cameras, deep space imagery from telescopes, microscopy, memory chips, electronic paper, heated pixel arrays, selective high density radio signal routing, and for selective curing of heat- or electro-sensitive materials.
  • CCDs charge-coupled devices
  • These integrated circuits, as well as many others typically include trace connections for each coordinate, which, even at moderate complexity levels, require multiple layers of circuitry patterns to ensure isolation of each signal. As such, multiple layers requiring mechanical connections have an increased complexity and incidence of continuity errors.
  • CTR Cathode Ray Tube
  • electrons are generated off of a tungsten filament in a vacuum tube, accelerated by a voltage differential through a focusing coil and diverted vertically and horizontally through biased electric fields in a consecutive scanning mode.
  • Radio signals are embedded directly into the synchronized scan mode as time and amplitude modulations and the electrons were decelerated against a screen of various phosphors which convert most of the electrons' energy into a lighted pixel.
  • CRT displays include a box like bulk, however, that quickly became an unwanted aspect as electronics for radio and computer chassis became smaller.
  • Plasma displays can be described as thousands of miniature fluorescent light cells that are turned on and off by higher voltage electrodes. Tn plasma displays, the same gasses used for neon signage are used in tiny isolated micro pixel cells. Plasma displays are fairly efficient but relatively expensive to fabricate. LCDs are slightly cheaper to fabricate but use a larger amount of wattage per lumen because of circuit complexities employing large numbers of solid state transistors. Current losses are also associated with the randomizing and ordering of the liquid crystals themselves. Also, realizing that backlit emission continues whether or not a pixel light gate is open or closed, energy losses become quite significant, especially with small compact portable devices such as laptop computers.

  • each trace can have its own discrete inductive or capacitive value associated thereto and, as a result, an associated characteristic resonant frequency, thereby allowing for the resonant frequency filtering utilized in and exploited by this invention through Cartesian intersection.
  • a plurality of frequencies can be sent through a central signal bus, thereby eliminating the need for many individually discrete multiples of traces for each row and column.

  • the thickness of the display unit can be reduced to a fraction of that generated by traditional display manufacturing methods.
  • the resonant frequency matrix method only the thickness of the preprinted substrates with the X- and Y-traces, the activation material sandwiched, and any filtering layers or methods used as aperture and colorants for the light emitted at each X- and Y- intersection point comprise the profile of the display.
  • the translation and conversion of the video signal to the appropriate bandwidths to activate the specific Cartesian coordinates of selected pixels in each of the RGB colors create the display image using the resonant frequency matrix.
  • Modification to existing display structure or methods may be required in some cases when utilizing the resonant frequency matrix to power the display. For example, anything that is typically DC accessed is only using half the waveform. This is significant because the pixel may need either more activation light emitting, more volume of emitting material, or more frequent accessing to compensate for the loss of light over time, to create an equal amount of display light. This can be achieved by tandem circuits or layers each utilizing half the waveform. Because of the advantages of the resonant frequency matrix activation method, even with these modifications display embodiments created with the resonant frequency matrix would still recognize benefit in cost and manufacturing, as well as resolution quality and a greatly thinner profile. Electroluminescent phosphors are dependent on a higher voltage alternating current to activate light emission.
  • LED technology works by a DC bias of much lower voltage than electroluminescent phosphors, which is a significant advantage, but if an alternating signal is applied it will take only one half of the alternating waveform, bypassing the other half.
  • the alternating signal on the traces of the resonant frequency matrix does, however, have an address density advantage over DC signaling and the initial half wave emission characteristic of LEDs may be compensated by quicker repetition via resonant pixel activation.
  • Electroluminescent material can be incorporated into a curable polymer matrix and applied like ink and cured after application by inexpensive heat or UV activation. Most effective LED/OLED applications are applied by CVD or ink jet or other means requiring a more restricted manufacturing environment.
  • a resonant addressing scheme allows DC addressing to a greater degree, so rather than have the waveform skip a beat every time it is illuminated it can be accessed a greater number of times per second than by DC addressing.
  • Crosstalk between close tolerance traces is minimal for resonant frequency matrix display applications. Tolerances required for very low amperage currents reduce inductive crosstalk possibilities and are at more of a minimum than the electric field crosstalk because of the higher voltages being used. High voltage does not seem to be a limiting factor of any serious significance with already existing LCD back lit displays. Voltages applied to the electroluminescent resonant frequency matrix display have a higher voltage than the LCD gates, and the traces in the RF display are on the same scale of distance. There are other concerns about the localized arcing caused by mediated defects in the film.
  • Various waveforms can be effective, the waveform influencing the duration and quantity of electrons activated. While on a sine wave the amplitude increases as current increases, on a square wave there is a rise time that is completely or nearly vertical with no x-axis component, chopped at the top, with a flat x-axis component at the top, and its fall time is a mirror image of the rise time, with the longest duration at the highest point of amplitude, giving it the name square wave.
  • This is a preferred waveform embodiment although others are also effective such as sine wave or triangular shaped wave.
  • Cholesteric displays, electrophoretic displays, and electrochromic displays can also be created incorporating the resonant frequency matrix for addressing the individual pixels of the displays.
  • the cholesteric displays, electrophoretic displays, and electrochromic displays can include cholesteric material, electrophoretic material, or electrochromic material for emitting electromagnetic radiation in response to alternating current conducted in both the first and second electrically conductive traces.
  • cholesteric liquid crystals, electrophoretic suspension, or electromeric material can be can be used to emit electromagnetic radiation in a display when alternating current is conducted in adjacent conductive traces.
