Abstract: A digital display timepiece having a panel of display elements which change their optical properties when electrically excited, an electronic circuit, the outputs of which are connected to the display elements, and a time base controlling the logic circuit, such that excitation of various sub-assemblies of said display elements controlled by the logic circuit displays the desired time, where the logic circuit and the display panel are so connected as to constitute a monolithic unit having a minimum number of input connections linking the output of the time base to the logic circuit.
