lm057qctt03 Sharp 5.7 inch tft lcd module
LM057QCTT03 is a 5.7‑inch color CSTN‑LCD LCM manufactured by Sharp, native QVGA resolution 320(RGB)×240 with 70PPI and classic 4:3 landscape aspect ratio. It adopts STN normally‑black transmissive display mode, 15‑pin 8‑bit parallel data interface, edge‑lit single CCFL backlight (requires external CCFL inverter board). This module integrates built‑in 4‑wire resistive touch screen (Film‑on‑Glass) on panel surface. This is an obsolete original industrial‑grade color display module, widely used for legacy CNC machine tools, old‑generation HMI operator panels, PLC control terminals and industrial test equipment screen replacement & refurbishment projects.
At zylcdshop.com, we supply well‑tested original Sharp LM057QCTT03 5.7‑inch CSTN‑LCD LCM with spot inventory. We support sample testing and bulk wholesale orders, provide complete datasheet, CCFL inverter matching consultation and touch signal debugging support service.

Product Features
LM057QCTT03 adopts mature Sharp CSTN color technology, mechanical dimension matches large amount of legacy 5.7‑inch HMI & CNC control devices, ideal for end‑of‑life equipment spare‑part replacement.
15‑pin parallel signal connector, 5.0V logic voltage, widely deployed on older industrial control mainboards, compatible with legacy hardware architecture.
Edge‑mounted single CCFL lamp unit, no built‑in inverter circuit, external CCFL high‑voltage inverter must be prepared separately for backlight operation.
Built‑in film‑glass 4‑wire resistive touch layer, touch signal independent from display interface, suitable for industrial man‑machine interactive operation scenarios.
Robust metal frame construction, designed for long‑time continuous operation in factory‑workshop environment, stable color graphic output for industrial control UI.
All Sharp LM057QCTT03 LCM supplied by ZYLCDSHOP are fully inspected and tested before shipment. Spot stock shortens urgent legacy‑equipment maintenance lead‑time.
