16-Lane V-by-One · 4K@120Hz | 4-Channel LVDS · 1080P@120Hz
Developed for TV LCM and T-CON board production testing. 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.
A professional LCM pattern test instrument — full-featured, well-protected and easy to operate
Up to 16-lane V-by-One (3840×2160/120Hz) or 4-channel LVDS (1920×1080/120Hz) — one instrument covers both mainstream interfaces.
All output signals have protection circuits; panel power features configurable over-voltage, under-voltage, over-current and no-load protection, preventing damage to the instrument and the panel under test.
48+ built-in common test patterns (including 3 dynamic scrolling screens); unlimited external images via SD card; up to 16 patterns per module parameter set.
Ready instantly at power-on — enters test mode immediately; 99 preset module parameter sets, so switching lines or panels means just switching a parameter number.
Three control modules supported: remote control (optional), numeric keypad (default), mouse (optional); signal on/off and pattern switching need only 3 buttons.
Supports fixture travel switches — press down to turn on the signal, lift to turn it off; test screens can auto-switch with independent per-image duration.

A full comparison of pattern-testing solutions for LCM production lines — professional instruments win across the board
| Item | 169-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 | — |
