Definitions

  • Adjacent sub-matrices- for displaying characters are preferably separated from one another by further energisable picture elements. These picture elements may be used in displaying those lower case characters that require a sub-matrix bigger than 5 X 5. Adjacent sub-matrices in the same row may be separated from one another by a single column of picture elements and adjacent rows of sub-matrices may be separated from one another by a single row of picture elements. This arrangement permits the display of contiguous graphics shapes. Adjacent sub-matrices in the same row preferably have a centre-to-centre spacing of 6 columns.
  • the functional components of the teletext receiver of Fig. 1 include the aerial - lO -
  • a front end amplifier is included in the tuning system 12 in order to provide the necessary UHF signal- receiving capability in compact form.
  • part of the alterable data store 18 is arranged to act as a character read only memory (ROM) and the remainder of the alterable data store 18 is used to store the page of data displayed as teletext information at any time.
  • the alterable data store 18 consists of 2048 X 8 addressable storage elements (nominally 2K X 8), 1024 X 8 elements of which are used as the current page store, that is, as the store for the data being displayed as teletext information.
  • the part of the alterable data store 18 arranged to act as a character ROM is made to receive the full range of ASCII control and display codes from a character and display code ROM located in the computer 13 when the receiver is first switched on.
  • the display device is divided electrically into an upper and a lower half each of 72 X 234 picture elements.
  • the upper half and the lower half are so connected electrically as to be driven simultaneously line by line.- That is, the data to be displayed is provided for the uppermost row of picture elements (row 0) at the same time as the data for row 72, followed by the data for rows 1 and 73, and so on, until the data has been supplied to all 144 rows (rows numbered 0 to 143).

Abstract

Un appareil d'affichage capable d'afficher une pluralité de caractères alpha-numériques comprend un dispositif d'affichage (2) consistant en une matrice d'éléments d'image disposés suivant une pluralité de rangées et de colonnes ainsi que des moyens d'activation de combinaisons sélectionnées des éléments pour afficher une gamme complète de caractères alpha-numériques. Tous ou pratiquement tous les caractères sont affichés dans une sous-matrice occupant uniquement 5 rangées et 5 colonnes de la matrice d'éléments d'image.
