LCD Monitor and Display

Backlight, panel-power, and signal-protection ICs for LCD / OLED / mini-LED displays

Magnias supplies the discrete components and small-signal ICs that complete the display power tree alongside the TCON and backlight driver IC. Our portfolio covers the synchronous rectifier MOSFETs in the backlight LED string driver, ESD/TVS protection on HDMI / DP / USB-C input ports, low-noise LDOs for the panel reference rails, and Schottky diodes for the boost-stage freewheel. Same parts scale across monitor (24-32"), notebook display, tablet, and large-format signage applications.

Application areas

LCD backlight LED driver

  • 60V / 100V N-Channel MOSFET (boost stage)
  • Schottky (freewheel diode)
  • Current-sense comparator
  • Open-drain dimming PWM

Panel-power & TCON support

  • High-PSRR LDO (panel reference)
  • Voltage supervisor (POR / sequencing)
  • Buck converter (sub-1V TCON core)
  • Level shifter (TCON ↔ host CPU)

Display input protection

  • ESD array (HDMI / DP / USB-C lanes)
  • CMF + ESD common-mode filter
  • Low-Cj ESD for high-speed lanes
  • TVS on power input

OLED / mini-LED variant

  • Sub-1V buck (high-current OLED core)
  • 30V dual N+N MOSFET (string switching)
  • Ultra-low-noise LDO (analog reference)
  • Photodiode bias LDO (brightness sensor)
