HITACHI TX09D80VM3CCA 3.5 Inch LCD Screen 240x320
The HITACHI TX09D80VM3CCA is a 3.5-inch color TFT-LCD display module with a resolution of 240x320 pixels (portrait orientation). It is designed for industrial applications such as PLC programming panels, medical equipment displays, and handheld instrumentation. This model is commonly used as a replacement part for HITACHI operator interfaces and other branded HMI units requiring a 3.5-inch screen with 18-bit RGB interface.
Display Characteristics
Active area: 53.64 mm x 71.52 mm. Pixel pitch: 0.2235 mm x 0.2235 mm. Viewing angle: 80° (left/right), 60° (up), 80° (down) (typical). Contrast ratio: 400:1. Brightness: 300 cd/m² (with LED backlight). Response time: 25 ms (Tr+Tf). Display colors: 262,144 (6-bit per color via 18-bit RGB). The screen is normally white transmissive type.
Interface and Signals
The LCD uses a 54-pin FPC (0.5 mm pitch) connector with the following signals:
Digital RGB 18-bit (R[5:0], G[5:0], B[5:0]).
Vertical sync (VSYNC), Horizontal sync (HSYNC), Data enable (DE), Dot clock (DCLK).
Logic supply voltage: 3.3V (I/O) and 5V (analog).
LED backlight: 6 LEDs in series, forward voltage 19.2V, current 20 mA (typical).
Timing supports VGA (640x480) scaled down by the controller or native QVGA (320x240) configuration. The module includes a built-in timing controller (T-con) and DC-DC converter.
Mechanical Specifications
Outline dimensions: 63.5 mm (W) x 84.8 mm (H) x 3.6 mm (D) (excluding FPC). Weight: 35 g. The LCD has four mounting holes (2.2 mm diameter) on the corners for securing to a frame. The FPC extends 25 mm from the bottom edge, with a stiffener for reliable connection.
Environmental and Reliability
Operating temperature: -20°C to +70°C; storage: -30°C to +80°C. Humidity: 10% to 90% non-condensing. The display is RoHS compliant. Vibration tolerance: 6.8 G (10–500 Hz) per IEC 60068-2-6. The LED backlight has a nominal lifetime of 50,000 hours (to half brightness).
Application in PLC/HMI Repair
The TX09D80VM3CCA is a direct replacement for failed screens in many HITACHI PLC programming terminals (e.g., HITACHI E series) and third-party HMIs. Before installation, verify the original screen’s FPC pinout and backlight configuration. The module does not include a touch panel; if touch functionality is needed, an external resistive touch overlay (4-wire) can be added.
Installation Notes
Electrostatic discharge (ESD) precautions are required when handling the LCD. Use a grounded workstation and avoid touching the FPC gold fingers. The mounting holes should be fitted with rubber grommets to absorb shock. The LED backlight driver must be constant current (max 25 mA) with a PWM dimming input (optional).
Compatibility List
Confirmed compatible with: HITACHI E610, E710, E910 series; also used in some Pro-Face and Beijer operator panels. For other brands, check interface compatibility (18-bit RGB, 3.3V logic). A conversion FPC might be required if the pinout differs.
Ordering and Support
Part number: TX09D80VM3CCA. The display is supplied in an anti-static bag with a dessicant. No driver board or cable is included. Technical datasheet (Hitachi Document No. TX09D80VM3CCA-00) is available upon request.
