摘要： A driver apparatus for an electroluminescent display comprising a plurality of rows to be scanned and a plurality of columns which intersect the rows to form a plurality of pixels, comprises addressable row drivers, each row driver applying an output voltage to its associated row when addressed. The value of the output voltage is approximately equal to the numerical average of the threshold voltage for the electroluminescent display and the voltage required to provide the maximum desired pixel luminance for the electroluminescent display. Bipolar column drivers each supply an output voltage to its associated column. The output voltage is either positive or negative depending on the desired luminance of the pixels. The range of both positive and negative column output voltages is from zero volts to about one half of the difference between the threshold voltage and the voltage to provide the desired maximum pixel luminance for the electroluminescent display.

摘要： The invention relates to a thick film dielectric electroluminescent display having a patterned layer. The patterned layer is patterned using a laser ablation method including selecting a wavelength of laser radiation, a laser pulse length, a laser energy density and a sufficient number of laser pulses to pattern the layer without substantial ablation of or damage to other layers, whereby the wavelength of laser radiation is such that the laser radiation is substantially absorbed by the layer with minimal absorption by other layers, the laser pulse length is sufficiently short that during the duration of the laser pulse there is minimal heat flow from the layer to other layers, and the laser energy density and the sufficient number of laser pulses is sufficiently high that energy is deposited in layer, whereby at least a portion of the layer is ablated and the luminance of an unablated area of the display is comparable to the luminance of an equivalent area of an unpatterned but otherwise identical display.

摘要： The invention is a novel sputter target and deposition method for multi-element thin film phosphors for thick film dielectric electroluminescent displays in which the deposited phosphors provide a high luminance and colors required for TV applications. The method comprises sputtering a single composite target in a low pressure sputtering atmosphere that comprises gases containing reactive species and non-reactive species. The composite target comprising a matrix phase and an inclusion phase, or two matrix phases, wherein one of the phases comprises one or more metallic elements that contribute to the composition of the phosphor and the other of the phases comprises the remaining elements that contribute to the composition of the phosphor. In the method the pressure of the reactive species within the sputtering atmosphere is varied to control the sputtering rate of the matrix and inclusion phases of the composite target to cause the ratio of the elements in the two phases to deposit in a desired ratio as a phosphor film on the substrate.
