🌗

Flicker (VCOM) Adjustment

I2C-based VCOM voltage adjustment; the control box offers +5 / -5 / +1 / -1 four-key fine-tuning, and the "Save" key writes the value to the panel T-CON board memory in one step.

🛡️

Quadruple Hardware Protection

All output signals are protected; panel power and backlight power feature configurable over-voltage, under-voltage, over-current and no-load protection; VCC / VBL support soft start to suppress inrush current at power-on.

📱

7-Inch Touch Control Box

The standard RMT-221 control box features a 7-inch capacitive touchscreen with full touch operation, a bilingual Chinese/English interface and dual operator/administrator permissions; an IR remote control can also switch signals and patterns.

🖼️

Four Types of Test Patterns

Editable RGB solid colors, card-algorithm built-in patterns, external BMP images from SD card, and scrolling bar patterns; frame-lock supported with independently set duration per frame and auto/manual switching.

🔗

Instant On & AOI Integration

Ready instantly at power-on — no boot wait. Store 99 sets of module parameters; switching lines or panels means just switching a parameter number. RS-232 commands let AOI equipment set parameters, switch signals, change patterns and read status.

SVG-2401 vs Motherboard Pattern Testing

A full comparison of pattern-testing solutions for LCM production lines — professional instruments win across the board

ItemSVG-2401 Professional Signal GeneratorOrdinary Motherboard
Versatility ✓Purpose-built for LCM and T-CON production-line pattern testing; card-based structure with optional cards, compatible with LVDS / V-by-One / eDP panels, up to 8K ✗One motherboard only drives its matching panel — changing glass means changing the board
Reliability ✓All interface signals have protection circuits; T-CON power features over-voltage, under-voltage, over-current and no-load protection ✗No protection — easily damaged
Efficiency ✓Instant on at power-up, highly efficient ✗Must wait for the motherboard to fully boot; some boot very slowly
Operability ✓Signal on/off and pattern switching with just 3 buttons ✗Must switch to the USB channel via remote or buttons first, then control USB image playback
Cost-Effectiveness ✓Designed service life of 5–10 years — better long-term value ✗Frequent damage or even scrapping — higher overall cost
Special Requirements ✓Independently developed — customization available for special panel-inspection processes ✗Cannot be met
Industry Trend ✓Major brand LCM manufacturers all use professional instruments for pattern testing —
Success Stories ✓Wistron, Innolux, AUO, Panda, BOE, TCL CSOT —
Import ReplacementPerformance rivaling imported instruments — a full replacement
Price AdvantageMuch more affordable than imported instruments

TROUBLESHOOTING

Troubleshooting

Quick ways to locate pattern-testing issues

  • Check that the signal card is properly seated and that the correct cables and adapter board are used;
  • Check that the correct power parameters and panel parameters are selected;
  • Turn on the output signal and check whether LVDSVCC current is normal — very low current or NCP usually indicates a cable error, or possibly wrong power parameters.
  • LVDS panels: check that the 6/8/10-bit width and JEIDA / VESA format settings match the panel datasheet;
  • V-by-One panels: check that lane count (1 / 2 / 4 / 8 / 16 lanes) and division (1 / 2 / 4) settings are correct;
  • eDP panels: check that lane count and rate (1.62 / 2.7 / 5.4 / 8.1Gbps) are within the panel’s supported range;
  • Also verify that the signal generator resolution matches the panel and that cables are intact.
  • Switch the "Flicker" parameter to the one matching the current LCM, and switch to the Flicker test pattern;
  • Press the +5 / -5 / +1 / -1 keys on the control box to adjust the VCOM value while observing flicker changes;
  • Once optimal, press the "Save" key to write the VCOM value to the panel’s non-volatile memory; a green "OK" in the status area means success, while a red "FAIL" requires readjustment.
  • The SPG-MAIN control card (with backlight driver) is standard; signal cards are selected by panel interface: V-by-One for TV panels, eDP or LVDS-P for notebook/esports panels, LVDS card for ordinary LVDS panels;
  • 8K panels need 4 V-by-One cards (64 lanes) or 2 eDP cards (16 lanes); cards of the same type can be mixed and paralleled to expand channels;
  • Later panel changes only require additional cards — no need to replace the whole unit. For selection help, contact us for a configuration plan.
