    Abstract: @ A method for structuring a display font for a full page display device for a text processing system in which a text stream input by way of a keyboard is stored and displayed to the operator on a display device including a cathode ray tube, the electron beam of which is modulated and scanned in a series of horizontal traces to produce an image of the text line on the screen of the display device. The method comprises blocking the characters making up the font to the extent that each character (32) is more distinguishable within a word, double dotting the vertical portions of the characters and single dotting the horizontal portions of the characters to provide even brightness characters so that operator eye fatigue is reduced and brightness can be lowered to reduce flicker.

    Abstract: A full page display device for a text processing system in which a text stream input by way of a keyboard is stored and displayed to the operator on a display device including a cathode ray tube, the electron beam of which is modulated and scanned in a series of horizontal traces to produce an image of the text line on the screen of the display device. The system comprises storage means which includes a plurality (four in a specific embodiment) of separate storage devices (47-54). In the specific embodiment, when the storage devices are accessed for display, one character is accessed simultaneously from the same location in each of the storage devices. The data is latched and coupled to a character generator (36) to read out character dot pattern data which is latched and then interleaved with the data from other accessed character data by transferring the data one character at a time in parallel to a serializer (70). The data out of the serializer forms a serial bit stream which is coupled to the cathode ray tube to modulate the intensity of the beam in synchronism with the sweep to display the selected character data.
