Title: Display device employing special purpose monograms

Abstract: An electric-optic display device having an electrically controllable optical means for selectively indicating one of the seven days of the week by means of a combination of two letters. The device comprises two arrays, a first array composed of a plurality of segments arranged in such a pattern that all of the letters positioned in the first place of the seven combinations expressing the 7 days of the week can be indicated. The second array is composed of a plurality of segments arranged in such a pattern that all of the letters positioned in the second place of the seven combinations can be indicated. The first letters of the days of the week are formed in uppercase letters, the second letters of certain days of some days of the week are formed about one-half as high as the first letters of the days of the week and the second letter of at least one day of the week is formed as a lowercase letter. Each segment of the first array is electrically controlled to indicate any desired day of the week and each segment of the second array is electrically controlled to indicate any desired date of the month.
