8.4-inch GOT1000 panel, 640x480 VA-grade display
The GT1665M-VTBA is a 8.4" TFT color liquid crystal display panel in Mitsubishi's GOT1000 line, listed with 640x480 dot resolution and a 65536-color palette wide enough for animated process graphics without resorting to dithering on operator screens. Active display area is 17.1 cm wide by 12.8 cm high, sitting in an external housing of 24.1 cm wide by 19.0 cm tall by 5.2 cm deep — the panel cutout is 22.7 cm wide by 17.6 cm tall, so a cabinet door retrofit must hold that cut tolerance before the unit clips in.
Resistive touch, 15 MB onboard flash, replaceable backlight
Touch input is analog resistive film — the well-trodden choice for gloved-hand operation on plant floors where a capacitive panel would false-trigger on water spray or fabric — and the on-board C drive carries 15 MB of built-in flash for both the project data and the runtime, enough for full-screen graphics plus screen logic without forcing an external memory card on every machine. Backlighting is a replaceable cold-cathode fluorescent tube, not an LED array — this matters for the MRO planner: CCFL life is shorter than the panel itself and a shutoff-detection function is on board, so screen-saver timing should be set to extend the tube rather than dismissed as a cosmetic preference. The lithium backup cell on the SRAM/real-time clock side is the GT15-BAT — confirm that spares are stocked if recipe retention matters across power cycles, since battery replacement on this generation is a planned maintenance task rather than a board swap.
Mature lifecycle — sourced through independent channels
Lifecycle is recorded as mature on the part record — Mitsubishi has moved new GOT1000 demand onto the GOT2000 generation, so GT1665M-VTBA is widely traded through independent distribution and surplus channels rather than the factory-new spot market, which is the right place to verify whether the backlight tube is new or refurbished at quote time.
