A method for the display of information by means of a multi-element passive display device, the elements being separately activated, matrixially arranged and at least two elements required to be activated for display of information. The type of display involves use of a liquid crystal cell formed of electrodes and counter-electrodes carried by two glass plates respectively and the said elements are parts of said electrodes and counter-electrodes. The method comprises the election for activation of elements which are adjacent in any direction, that is, either those superposed, or side by side or diagonally arranged. This method enables use of conventionally shaped characters of greater individual size than heretofore available and is useful for display of dates and/or days of the week on electro-optic watches.
A method for the display of information, especially for watches, using a display device of the type comprising several elements arranged in a rectangular formation, said elements being separately activatable, at least a group of at least two of said elements being required to be activated to effect the said display, said method comprising the steps of:
