Screen · diodes

An LED wall is a grid of tiny lights with dark space between them, built from panels bolted side by side. LED rebuilds your picture as that grid, from a fine screen to a stadium wall you could count.

## Controls

### Panel

- **Pitch** (hero knob, 4px to 24px, rests at 10px). The hero. The distance between diodes. Small is a fine screen, large is a wall you can count.
- **Diode size** (Knob, 0 to 100, rests at 65). How big each diode is in its cell. Smaller leaves more black between them.
- **Glow** (Knob, 0 to 100, rests at 45). Soft light around each diode.

### Signal

- **Levels** (Knob, 2 to 16, rests at 9). How many brightness steps each color gets. Low bands the picture into flat steps.
- **Unlit diodes** (Knob, 0 to 100, rests at 35). In the dark parts of the picture you see the unlit diodes, as dim grey dots.
- **Shape** (Switch: Round / Square). **Round** or **Square** diodes.

### Color

- **Color** (Select: Full color / Amber / Red / Green / Ice). **Full color**, or a single-color sign in Amber, Red, Green or Ice.

### Wall

- **Module seams** (Knob, 0 to 100, rests at 0). The wall is built from square modules. Each one sits a little brighter or darker, with dark seams between.
- **Diode variation** (Knob, 0 to 100, rests at 0). Each diode is a little brighter or dimmer than its neighbor.
- **Dead diodes** (Knob, 0 to 100, rests at 0). Some diodes are out, and a few are stuck on red.

### Camera

- **Refresh bands** (Knob, 0 to 100, rests at 0). Dark bands roll through the picture, the way a camera sees a screen refreshing.
- **Moiré** (Knob, 0 to 100, rests at 0). A rainbow interference pattern drifts over the wall, once a loop, like a camera filming the grid.
- **Viewing angle** (Fader, -100 to +100, rests at 0). Seen from off to one side. The panel dims toward its edges and shifts color, warm on one side and cool on the other.
- **PWM flicker** (Knob, 0 to 100, rests at 0). A fast strobe, the diodes pulsing too quickly for the eye but not for a camera.

## Presets

- **Stadium Wall**: Big modules with seams, uneven diodes and a few dead ones.
- **Filmed Screen**: A screen caught on camera: rolling refresh bands and rainbow moiré.
- **Off Axis**: Seen from the side: dim and color-shifted toward one edge.
