RONEN Display Engineering Tools
Free, no-signup calculators used by display engineers to size brightness, pick interfaces and specify modules faster. Built by the RONEN application engineering team.
Converters & Signal Generators
Display Interface Selector →
Answer 3 questions to pick the right interface: SPI, RGB, LVDS, MIPI DSI or eDP.
PCLK & Bandwidth Calculator →
Pixel clock (MHz) and RGB / LVDS / MIPI bandwidth from resolution and frame rate — with an interface recommendation.
Display Unit Converter →
Pixels ↔ mm, inch ↔ mm, nits ↔ fL, mils ↔ mm, DPI and °C/°F for engineers.
PPI & Display Specs Calculator →
Resolution + diagonal → PPI, pixel pitch, active area (mm) and aspect ratio, with matching standard modules.
MCU Display Timing Generator →
Active resolution, porches and sync → H/V totals, frame rate, pixel clock and a copy-ready RGB/LTDC snippet.
Power, Optical & Mechanical Calculators
LCD Brightness Calculator →
Calculate the minimum nits you need for your ambient lighting, with optical-bonding recommendations.
Backlight Power & Thermal Estimator →
LED power (W) and drive current behind a target brightness — before your power budget freezes.
Sunlight Readability Estimator →
Effective outdoor contrast from ambient light, panel nits, contrast ratio and optical bonding. Verdict: readable, marginal or washed out.
FPC Bending Radius Calculator →
Minimum safe FPC bend radius by thickness, layer count and static vs dynamic folding — copper-fracture risk verdict included.
Display Power Budget & Battery Runtime Estimator →
Sum backlight, controller and touch draw to size supplies and estimate battery runtime.
Viewing Distance & Character Height Calculator →
Minimum and recommended character height from viewing distance — or the max distance for your font size.
Brightness Derating Calculator →
Real brightness at high or low ambient temperature from the rated nits — plus the rating you need to hit your target.
Backlight L70 Estimator →
Estimated L70 hours at your operating temperature from the rated lifetime, using the 10 °C LED rule.
Display Cutout & Bezel Calculator →
Recommended bezel opening from the active area, with clearance and tolerance guidance for enclosure design.
Selection & Finder Tools
LCD Replacement Finder →
Search discontinued Mitsubishi / Innolux / NEC panels for published drop-in replacements, or match our 190+ in-stock catalog by size, resolution and interface.
Capacitive Touch Cover-Glass Thickness Calculator →
Check the maximum cover-glass thickness your PCAP/CTP sensor can sense, by architecture.
Display Finder →
Filter our in-stock TFT LCD modules by size, resolution, interface, brightness, panel type and touch.
Touch Technology Selector →
Six questions on gloves, moisture, EMC and budget → capacitive or resistive recommendation with reasoning.
TFT LCD Module Comparator →
Pick any two in-stock modules and compare every key spec side by side, differences highlighted.
