Overview

LT121AC31U00 adopts low-power LTPS thin-film transistor technology, lower power consumption than conventional a-Si industrial panels, stable for long-term static parameter display in factory workshops and medical equipment rooms.

Classic 4:3 SVGA 800×600 square resolution perfectly matches legacy CNC, PLC and medical device control firmware without UI stretching or compression. Single-channel 20Pin LVDS differential signal features strong anti-electromagnetic interference performance, stable image output in complex electromagnetic environments such as machining centers and injection molding workshops, compatible with most old industrial embedded motherboards and universal LVDS driver boards.

  6. Replacement spare panel for Toshiba LT121AC series 12.1-inch CCFL SVGA LTPS TFT modules

 FAQ

Q1: Does LT121AC31U00 need an external CCFL inverter?

A1: Yes, equipped with dual CCFL tubes without onboard high voltage drive circuit. A matched dual-channel CCFL high-voltage inverter is mandatory; WLED driver boards cannot be directly compatible.

Q2: What is LTPS technology advantage compared with ordinary a-Si panels?

A2: LTPS has higher carrier mobility, lower power consumption, thinner circuit layout, better static image anti-burn-in performance, more suitable for long-hour continuous industrial display.

Q3: Can this panel connect HDMI/VGA signal sources directly?

A3: It only supports single-channel LVDS input; an extra LVDS to HDMI/VGA conversion driver board is required for analog/digital signal access.

Q4: What temperature environment can this panel adapt to?

A4: Operating temperature 0℃ ~ +50℃, only suitable for constant-temperature indoor workshops and medical equipment rooms; cannot adapt to cold storage or vehicle-mounted extreme low temperature environment.

Q5: Does this module come with touch screen by default?

A5: Bare LCD only without integrated touch sensor. To build touch HMI/monitor, separate matched 12.1-inch 4-wire resistive touch digitizer needs optical bonding.
