    (LCD 10.1″ 4K X 2K (3840X2160) RGB )

    Professional cinema and broadcast monitoring workflows demand the 4K native resolution (3840×2160) and 10.1-inch form factor of this JDI LCD for color-critical content review and on-location production grading. Medical imaging systems and ultrasound display consoles also utilize ultra-high resolution compact panels to visualize fine anatomical or diagnostic detail in space-constrained operating rooms and mobile ultrasound carts.

    Current-sense and power distribution circuits in server power supplies and battery management systems depend on precise 0.5 Ω shunt resistors to monitor load current and enforce circuit protection thresholds with ±0.5% accuracy. Motor drive circuits and industrial welding equipment similarly use low-ohm metal film resistors to establish feedback networks for real-time thermal and overcurrent monitoring.
