Electro-transmissive display device |
摘要 |
A digital display device for forming one or more electro-transmissive display patterns, which comprises a pair of oppositely disposed electrodes to which a signal is supplied for energization. Each of the electrodes includes a number of electro-conductive sections which are disposed with a lower distribution density at the central portion and with a higher distribution density at the contour portion. This mode of distribution of the sections gives an equivalent visual contrast to the situations in which all the sections are disposed with a uniform distribution while at the same time reducing the power consumption rate.
