    Abstract: A display screen with a plurality of display lines contains a storage (34) that receives lateral offset values for each line to be displayed. When the corresponding line is to be displayed, the offset value is transferred from the storage (34) to an offset register (22), whose outputs control a multiplexer (26) to select an appropriately delayed output tap of a shift register, containing the signals to be displayed.

    Abstract: A digital data rester display apparatus in which character codes, character attributes and field attributes are used. Means are provided to specify the mode of operation and to select the control mode. Depending on the specified mode the storage pattern in the re-fresh memory is varied. A first control mode stores field attributes only and the second control mode stores character attributes. A third mode mixes both field and character attributes. In the first mode the re-fresh memory stores either field attributes or character codes in such of a plurality of sequentially addressable locations. In the second mode character codes and character attributes are stored at alternate address.
