Abstract

A text receiver, particularly but not exclusively a teletext receiver, is capable of displaying a full page of information while having dimensions permitting it to be held in a user's hand. The receiver includes: (i) signal-receiving means including aerial means arranged to receive signals representing text information, (ii) signal-processing means arranged to process signals from the signal-receiving means and to provide information signals for display, (iii) a display device (2) capable of displaying a page of information, and, (iv) a keyboard for selecting the page of information for display. The display device includes a matrix of picture elements arranged to display characters as sub-matrices. The device is capable of displaying a full range of alpha-numeric characters with all or substantially all of the characters being depicted by a 5 x 5 matrix of picture elements. The receiver may include storage means for storing the number of a page of information that has just been displayed and control means operable by a user to cause the receiver system to display again that page of information.
