16-Lane V-by-One | 4-Channel LVDS | 8-Lane eDP | Flicker Adjustment
One instrument integrates 16-lane V-by-One, 4-channel LVDS and 8-lane eDP outputs, covering production testing of TV, monitor and notebook LCMs and T-CON boards. I2C-based Flicker (VCOM) adjustment supported; split-type RMT-220 control box included; output interfaces feature quadruple protection (over-voltage / over-current / under-voltage / no-load); the whole test requires only 3 buttons.
A 3-in-1 LCM pattern test instrument — one unit covering TV, monitor and notebook production lines
Up to 16-lane V-by-One (4096×2160@120Hz), 4-channel LVDS (1920×1080@120Hz), 8-lane eDP (up to 5.4Gbps, 2560×1440@240Hz) — one instrument handles all three interface types.
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.
All output signals have protection circuits; panel power and backlight power feature configurable over-voltage, under-voltage, over-current and no-load protection, preventing damage to the instrument and the panel under test.
The standard RMT-220 external control box sits separately from the main unit for flexible placement on the line; dedicated EDID-read and backlight-adjustment keys; frequently used keys are mechanical keys rated for millions of presses.
96+ built-in common test patterns, continuously updated per user requests; unlimited external images via SD card; up to 32 patterns per module parameter set, with auto-play and per-image duration settings.
Ready instantly at power-on — no boot wait. Multiple module parameter sets can be preset; switching lines or panels means just switching a parameter number. The RS-232 port supports fixture travel switches — press down to turn on the signal, lift to turn it off; serial protocol customizable.

A full comparison of pattern-testing solutions for LCM production lines — professional instruments win across the board
| Item | SVG-2203 Professional Signal Generator | Ordinary Motherboard |
|---|---|---|
| Versatility | ✓Purpose-built for LCM and T-CON production-line pattern testing — one instrument compatible with LVDS / V-by-One / eDP panels | ✗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 | — |
