"Digital" alphanumeric schemes, and use of similar schemes in East Asian languages

Factual Questions

I am trying to find out what exactly to call the following types of alphanumeric schemes. The first is the familiar calculator/high-school gym scoreboard numerical scheme. The second is a more complex set-up meant to accomodate the Roman alphabet:

Second question: Have either Japanese, Korean, or Chinese speakers ever adopted a similar scheme for their own numerals (or even some “word-characters”)? I am aware that speakers of these languages are as familiar with Arabic numerals as we are, so maybe there’s never been a perception of acute need.

These are generally known as seven segment and fourteen or sixteen segment displays. See the Wikipedia entries for seven , fourteen and sixteen segment displays. The representation you have shown, which would be a 19 segment display, doesn’t exist. The horizontal bars are only two segments, not three. As far as I know, there is not a name for the alphanumeric scheme.

They do provide a fairly clumsy alphabetic display, but don’t allow for easy upper and lower case. Dot matrix displays have just about taken over for those uses.
