ABSTRACT:
An optical disc playback and display apparatus comprising a playback block for reproducing the optical disc recorded with large quantities of character information or image information, a display block, rectangular in shape, for displaying reproduced character information or image information, and a touch panel input block superimposed on the rectangular display block. The novel constitution eliminates use of a conventionally practiced hardware keyboard, making the apparatus far thinner and therefore more portable as well as enhancing ease of search data input.
