  • System and method to drive display matrix
    Patent number: 8487855
    Abstract: A system and method to drive display matrix, comprising: a voltage level generator to provide predetermined voltages, a row voltage selector to select a group of voltages from the voltage level generator depending on select vector to drive row drivers, a column voltage selector to select a group of voltages from the voltage level generator depending on data vector to drive column drivers, and a controller to generate control signals to scan the display as dictated by addressing technique.

  • Method and system for line by line addressing of RMS responding display matrix with wavelets
    Patent number: 8115717
    Abstract: A method for line-by-line addressing of RMS responding display matrix with wavelets, said method comprises steps of: selecting the wavelets such that energy of them is proportional to an integer power of two to form a wavelet matrix; obtaining select waveform profile by summing elements of column in the wavelet matrix; obtaining column waveforms by dot product of data with column of the wavelet matrix; and applying the select waveform and the corresponding column waveforms by selecting one row of the display matrix at a time.

  • Method to display gray shades in RMS responding matrix display
    Patent number: 8081179
    Abstract: A method to display gray shades in RMS responding display matrix, includes: selecting each row of the display matrix with a set of “s” discrete select voltages in a sequence or random and applying a set of discrete data voltages to a column of the display matrix wherein the data voltages are of both polarities and energy of the select and data waveforms that are applied to rows and columns are constants during the “s” time intervals for all the rows and columns to display gray shades in RMS responding display matrix.
