The filled cells are upper left, upper right, and lower left. Teletext numbers its 2 × 3 mosaic across the rows: 1–2 at the top, 3–4 in the middle, and 5–6 at the bottom.

Teletext began in the UK as a broadcast information service in the early 1970s. Its mosaic mode let designers make simple graphics, such as maps, from character cells. In separated mode, each filled cell has a narrow border of background. Unicode later encoded the separated forms so emulators and existing software could preserve this display style.
