# LCD v1 — Flipper Zero

A 128 by 64 orange-backlit LCD of a pocket multi-tool cycles through its screens, dissolving between them. Every screen is painted into a 1-bit buffer, then drawn as a grid of dark cells casting shadows on the glow.

A small handheld screen sits in a dark bezel on a near-black ground, orange
behind the glass and brighter at the centre. Dark square pixels draw a menu of
icons and labels with a highlighted row and a scrollbar, then a frequency
analyzer, a raw signal capture, a card reader, a typed message ending in a
blinking block cursor, and a dithered plasma. Each screen hands over to the next
through a dissolve, and moving parts leave a faint smear.

Each screen is a function of the loop phase that fills a 128 by 64 array of bits
using lines, rectangles, arcs, bitmap icons and a pixel font; noise is a hash of
an integer tick, not a clock or random call. The dissolve blends two frames
through an ordered dither threshold. A panel routine then fills one path of
rectangles per layer: unlit cells, a ghost of the frame a few hundredths of a
second earlier, offset shadows, lit cells, and a glare band.
