Coming soon · Desktop app going web

Map, animate & simulate LED matrix screens, right in your browser.

Led Shows Web brings the full Led Shows desktop toolkit online: configure LED panels and driver chips, draw pixel maps, layer real-time effects, preview the result on a GPU-powered simulator and export straight to Led pannel controller cards. You don't need to install anything.

What is Led Shows?

One tool from bare LED module to running show

Led Shows by Caronon Team is a professional Windows application for designing irregular and large-format LED screens driven by led controller cards. It handles the whole chain: describing each LED module, arranging modules into any shape, wiring data paths, creating content, simulating the final output and generating the card files.

Led Shows Web takes the same core features to the browser. It runs on any OS and tablet, keeps projects in the cloud, supports team sharing, and keeps compatibility with existing .Map, .Proj and .pcfg files.

Desktop today

  • Windows only (WinForms + OpenGL)
  • Local installation & license
  • Files shared manually

Web tomorrow

  • Any modern browser, any OS
  • Sign in & start, with auto updates
  • Cloud projects & team sharing
Main features

Everything the desktop app does, rebuilt for the web

Each module below exists in the desktop Led Shows today and is planned for the web version.

LED panel & chip library

Define modules by width, height, scan rate and data lines. Pick from 12 driver chips and save reusable .pcfg panel profiles in a searchable catalog.

  • Panel wizard
  • Pixel maps
  • .pcfg

2D mapping editor

Lay out modules on a canvas in any shape: grids, circles, letters, curved façades. Draw matrix or circle arrays, rotate in 15° steps, mirror and align, with full undo/redo.

  • .Map
  • Mirror / rotate
  • Background image

Data wiring & auto-detect

Connect blocks into data chains, flip input/output and see the signal path. Auto-detect panel configuration and layout, then export a printable wiring diagram as PDF.

  • Connect blocks
  • Auto-detect
  • PDF wiring

Layered real-time effects

Stack effect layers with opacity and ordering: border, image, full-master color, scrolling text, video, video mask/shader, 3D video and meteor, plus neon, fire, firework and color shaders.

  • 8 layer types
  • GLSL shaders
  • Masks

GPU simulation & preview

See exactly what the physical screen will show. A GPU-accelerated simulator renders the mapped pixels in real time, with an external full-screen preview for clients.

  • Real-time
  • External preview
  • .Proj projects

Video import & export

Bring in MP4 footage up to 4K, map it onto your layout and render the final mapped video with configurable resolution, frame rate and quality.

  • Up to 4K
  • FPS / bitrate
  • Mapped output

Multi-language & themes

The full interface is available in Vietnamese, English, French and Chinese. It uses a dark, studio-friendly theme with large, touch-ready controls on the web.

  • VI · EN · FR · ZH
  • Dark UI
  • Touch-ready

Licensing & accounts

Secure, server-validated licensing with session watchdog. Web users sign in once and their license follows them across devices.

  • License server
  • Multi-device
  • Dashboard

Project files & import

Open and save native .Map maps and .Proj projects, and import .EMap layouts. Desktop files open unchanged in the browser.

  • .Map
  • .Proj
  • .EMap import

New on web: cloud & collaboration

Projects stored in the cloud with version history, shareable preview links for clients and team workspaces for installers and designers.

  • Version history
  • Share links
  • Teams

Feel the simulator: pick an effect

A lightweight in-browser taste of the Led Shows effect engine running on a virtual LED matrix.

Mapping editor

Any shape. Any wiring. Zero guesswork.

Real installations are rarely perfect rectangles. The mapping editor lets you place each LED module freely, then chain them into data lines. Led Shows calculates the pixel order the controller needs automatically.

  • Draw matrix and circle arrays in one click
  • Connect blocks, flip I/O and reorder data chains
  • Mirror horizontally/vertically, rotate by 15°
  • Trace over a photo or CAD background image
  • Auto-detect panel configuration & layout
  • Export a wiring PDF for the installation crew
Workflow

From module to show in five steps

  1. 01

    Configure panels

    Choose size, scan and driver chip, or load a saved .pcfg from the library.

  2. 02

    Build the map

    Place modules on the canvas and connect data chains. Save as .Map.

  3. 03

    Design content

    Stack effect, text, image and video layers into a .Proj project.

  4. 04

    Simulate

    Preview the real pixel output on the GPU simulator and show it to your client.

Hardware support

Driver chips & file formats

Accurate chip-level pixel maps, so what you simulate is what the screen shows.

How the desktop engine moves to the browser

The portable Led Shows.Core library (panels, chips, geometry, file formats, card packing) has zero external dependencies. That makes it ready to run on the web unchanged via WebAssembly.

FAQ

Questions

Will my existing desktop projects open in the web version?

Yes. The web version uses the same core library for .pcfg, .Map and .Proj, so existing files open as-is.

Which browsers are supported?

Recent versions of Chrome, Edge, Firefox and Safari support editing and simulation.

Does it work offline?

The web app is planned as an installable PWA. Once installed, mapping, simulation and export work offline; cloud sync resumes when you reconnect.

Will the desktop app still be maintained?

Yes. Both apps share the same core, so fixes and new chip drivers reach desktop and web at the same time.

Is my content uploaded to the cloud?

Only if you choose cloud storage. Simulation and export run locally in your browser on your own GPU.
