OLED Screen Guardian EN

OLED Screen Guardian is a browser extension designed to help reduce the risk associated with displaying static elements on-screen for extended periods by placing an animated protective overlay over a tab. Specifically tailored for OLED screen protection, the tool offers a simple interface via the browser popup, a dedicated Guardian page, on-screen controls, keyboard shortcuts, multilingual support, and an optional automatic mode that activates after a period of inactivity on visible web tabs. The extension serves as a practical OLED protector, designed to be launched quickly from the popup to temporarily cover the current page with animated graphics when the tab remains idle or when you step away from the screen.

The extension offers two main modes. Full mode protects the entire tab, while partial mode animates only specific areas. This distinction allows you to choose between total coverage when leaving your workstation and a more selective animation when you simply want to introduce movement without completely obscuring the content. Once activated, the Guardian displays animated visual patterns rendered on a canvas. The code specifies different pattern sets based on the selected mode: full-screen options include "Aurora," "Waves," and "Mosaic," while partial mode features patterns such as "Orbits," "Bands," and "Panels." These visuals are animated and adjustable, going beyond simple static images.

Another key feature is the level of control available during use. Users can pause or resume the animation, adjust the speed, modify the brightness of the visual effects, switch patterns, close the Guardian, and—in full mode—request a full-screen display. The documentation notes that the brightness setting affects only the displayed animation and does not alter the monitor's physical brightness. A visual HUD interface is also included to display the active mode status, speed, brightness, selected pattern, and helpful indicators, allowing for a quick understanding of the current situation.

The popup offers more than just a simple activation button; it also features an automatic mode capable of launching the Guardian after a set period of inactivity on a visible web tab. This delay can be configured in seconds or minutes, with validation and limits enforced via stored settings. When enabled, the extension monitors various forms of user activity, such as pointer movement, clicks, keyboard usage, scroll wheel action, and touch interactions. If no activity is detected within the chosen timeframe, protection starts automatically using the preferred mode and selected language. If activity resumes, the automatically launched Guardian closes, making the extension particularly well-suited for passive protection following inactivity.

The package also demonstrates careful handling of browser conditions. Automatic mode requires permission to access websites, and the extension adjusts script registration based on whether this mode is enabled and the necessary permissions are available. Automation works on visible HTTP and HTTPS pages while accounting for restricted pages and scenarios where access to file URLs must be enabled to work with local files. The popup displays helpful status messages—for instance, when no active tab is found, a page is restricted, a controller is unavailable, or a permission is missing.

Multilingual support is another key feature. The extension includes translations for English, Mexican Spanish, Brazilian Portuguese, Italian, French, Russian, Ukrainian, and Japanese. The language choice applies to both the popup and the Guardian controls, and the setting is saved to ensure a consistent experience. The popup also includes an "About" section that identifies the author as Néctar Suárez, displays the installed version, and offers an optional PayPal donation button.
