16-Lane V-by-One · 4K@120Hz | 4-Channel LVDS · 1080P@120Hz | Flicker Adjustment
An upgrade of the 169-VL, developed for TV LCM and T-CON board production testing. Newly added Flicker (VCOM) adjustment; standard split-type RMT-20 control box; output interfaces feature quadruple protection (over-voltage / over-current / under-voltage / no-load); the whole test requires only 3 buttons — simple, easy, stable and reliable.
An upgraded professional LCM pattern test instrument based on the 169-VL — with new flicker adjustment and smoother operation
Up to 16-lane V-by-One (3840×2160/120Hz) or 4-channel LVDS (1920×1080/120Hz) — one instrument covers both mainstream interfaces.
I2C-based VCOM voltage adjustment; the control box offers +5 / -5 / +1 / -1 four-key fine-tuning, and the OK 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-20 external control box sits separately from the main unit for flexible line placement; frequently used keys are mechanical keys rated for millions of presses.
54+ built-in common test patterns, 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. 99 preset module parameter sets; 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.

| Unit Specifications | Dimensions 350 × 350 × 180 mm (with packaging); weight approx. 3.6 kg (with packaging); power AC 220V (200–240V) 50/60Hz; operating temperature 0°C to +40°C |
| Operation | Split-type RMT-20 control box (standard, connected via DB15 cable); testing requires just 3 buttons — signal on/off, previous, next; plus VCOM adjustment and auto-play keys |
| Standard Accessories | RMT-20 control box, 16GB SD card, national-standard power cord, DB15 cable, universal LVDS adapter board (8762-V1), 50-wire LVDS ribbon cable, 51PIN / 41PIN V-by-One adapter boards and short cables (more adapter boards and cables available on request) |
Main unit front panel, rear panel and RMT-20 control box layout at a glance
Connects to the main unit via DB15 cable, with its own display and parameter menu. The "⏻" key controls the signal, "◀" "▶" keys switch test patterns, with an additional auto-play toggle; VCOM +5 / -5 / +1 / -1 keys fine-tune flicker, and the OK key saves. Frequently used keys are mechanical keys rated for millions of presses — built to last.

A full comparison of pattern-testing solutions for LCM production lines — professional instruments win across the board
| Item | 209-VL Professional Signal Generator | Ordinary TV Motherboard |
|---|---|---|
| Versatility | ✓Purpose-built for LCM production-line pattern testing, compatible with all LVDS and V-by-One panels | ✗One TV board 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 TV board 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 first, then play USB images |
| 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 | ✓Skyworth, Changhong, Innolux, AUO, Panda, BOE, TCL CSOT | — |
