EMC (electromagnetic compatibility) is the ability of an electronic device to operate correctly in its electromagnetic environment – without causing excessive interference to other devices and without being affected by external electromagnetic disturbances. EMC covers both the emission of disturbances (EMI) and the immunity to them (EMS – Electromagnetic Susceptibility).
For displays and control systems, this means limiting interference generated by LED backlights, clock signals or data links (e.g. LVDS, MIPI), and ensuring resistance to pulses, electrostatic discharges and ambient noise. Standards such as IEC 61000 or EN 61000 define the requirements and test methods that devices must meet for market approval. EMC is critical in industries like industrial, medical, transportation and railway, where reliability and safety are paramount.
