I remember doing that too on my Casio FX550

When I used to work in the electronics arena, we had some gas monitoring alarm panels (used in hospitals mainly) and the only display at the time that gave the best readability in all lighting situations were those vacuum fluorescent displays, made by Noritake/ITRON. Just before I left they were working on updating the displays to use OLED technology. In some situations an LCD would get washed out.
