Kyocera TCG057QV1CA-G00 5.7 Inch 320x240 QVGA TFT LCD Display Panel
Product Overview
The Kyocera TCG057QV1CA-G00 is a highly reliable 5.7-inch a-Si TFT-LCD module featuring a classic 320x240 (QVGA) resolution and a 4:3 aspect ratio. Engineered specifically for harsh industrial environments, this panel delivers excellent contrast and readability for HMI (Human Machine Interface) applications. Equipped with a robust 33-pin CMOS interface and a single-lamp CCFL backlight system, it serves as the perfect direct drop-in replacement for aging Kyocera, Optrex, and Hitachi 5.7-inch displays used in CNC machines, injection molding controllers, and medical equipment.
⚠️ Crucial Technical Notice Before Purchasing:
Please carefully verify your equipment's hardware before ordering to avoid compatibility issues:
CCFL Inverter Requirement: This LCD module uses a 1-piece CCFL backlight and DOES NOT include the built-in high-voltage driver circuit. Your machine's motherboard or an external CCFL Inverter Board (High Voltage Board) must be working perfectly to light up the screen. If your screen flashes red/pink and goes black, your inverter board is likely dead, not the LCD panel.
Interface Verification: This panel utilizes a 33-pin CMOS (1 ch, 6-bit) connector. It is NOT compatible with standard 20-pin LVDS or 40-pin TTL interfaces. Please count the pins on your original cable before ordering.
Product Features
Legacy Brand Compatibility: Directly replaces older Optrex and Hitachi 5.7" QVGA panels (Kyocera acquired these display divisions), ensuring a perfect mechanical fit.
Industrial-Grade Durability: Built to withstand factory vibrations, dust, and wide temperature fluctuations typical in manufacturing plants.
Standard CMOS Interface: Features a reliable 33-pin connector, ensuring seamless integration with older industrial PLCs and driver boards.
High Readability: Optimized contrast ratio ensures clear visibility of machine parameters, alarm codes, and trend charts on the shop floor.
Exact Mechanical Fit: Matches the original mounting holes and outline dimensions of legacy 5.7-inch HMI modules.

Frequently Asked Questions (FAQ)
My old screen says "Optrex" or "Hitachi". Will this Kyocera TCG057QV1CA-G00 work?
Yes, absolutely. Kyocera acquired the display divisions of Hitachi and Optrex years ago. The TCG057QV1CA series is the direct continuation of those legacy 5.7-inch 320x240 panels. As long as your original screen has a 33-pin CMOS interface and similar outline dimensions, this Kyocera panel is a perfect drop-in replacement.
Why does my new TCG057QV1CA-G00 screen show a dark screen but has a faint image when I shine a flashlight on it?
This indicates the LCD matrix and CMOS signals are working perfectly, but the CCFL backlight is not turning on. Because this panel requires an external CCFL inverter board, this issue is almost always caused by a faulty inverter board on your machine, a blown fuse, or a disconnected CCFL lamp wire. Please check your high-voltage board.
Does this 5.7 inch TFT screen include a touch panel digitizer?
No, this listing is for the inner TFT LCD display module only. It does not include a resistive or capacitive touch screen overlay. If your equipment requires touch functionality, you will need to source a separate 5.7-inch touch digitizer that matches your machine's specific bezel.
