The SX14Q004 is an original 5.7-inch TFT-LCD display panel from KOE (Kaohsiung Opto-Electronics, formerly Hitachi), featuring a QVGA resolution of 320(RGB)×240 pixels with a 4:3 aspect ratio and RGB vertical stripe pixel arrangement. The active area measures 115.2(W)×86.4(H) mm, with an outline dimension of 167(H)×109(V)×9.2(D) mm It delivers a typical brightness of 200 cd/m² and a contrast ratio of 40:1 (Typ.). The viewing angles are 45/45/35/45 (Typ.)(CR≥2 (left/right/up/down), with a response time of 30 ms (Typ.)(Tr+Td) . The panel operates in TN mode (Normally White, Transmissive) , supporting Color, 46% NTSC . It uses an Analog RGB (RGB parallel) interface with a 31-pin or 33-pin connector, requiring a 3.3V or 5.0V (Typ.) power supply for logic . The backlight is CCFL (Cold Cathode Fluorescent Lamp) type with two CCFL tubes, requiring an external inverter (typical input 12V). Environmental specifications include an operating temperature range of 0°C to +60°C and storage temperature of -20°C to +70°C
SX14Q004 KOE lcd display panel Key Highlights:
This KOE (Hitachi) display panel delivers QVGA 320×240 resolution with proven industrial-grade reliability, making it ideal for medical equipment displays, industrial control panels, test and measurement instruments, and navigation systems. The high 200 cd/m² brightness ensures excellent visibility even in brightly lit indoor environments, reducing operator eye strain during extended use. With 40:1aspect ratio, this panel provides the classic square format preferred for many legacy industrial and medical applications where vertical content presentation is critical. The Analog RGB interface allows for direct drop-in replacement and seamless compatibility with existing industrial controllers and embedded systems without hardware redesign. The high-contrast TN technology delivers sharp text sharpness and clear graphics for operator interfaces and data display terminals. The wide operating temperature range (0°C to +60°C) ensures reliable performance in industrial environments, factory floors, and medical facilities. The sturdy 13.0 mm thickness and robust mechanical design provide vibration resistance for demanding applications. The dual CCFL backlight design offers uniform illumination across the entire screen. For extended lifespan and lower power consumption, this panel can be retrofitted with modern LED backlight replacement kits (available separately). The panel features anti-glare surface treatment (Haze 25%) to reduce reflections and improve readability under ambient lighting conditions. This KOE panel is suitable for 24/7 continuous operation in critical applications such as patient monitors, CNC machine displays, and laboratory equipment. RoHS compliant version available for new installations. Please note that the original CCFL backlight requires an external inverter (not included) – for new designs, consider SX14Q006 or SX14Q009 LED-backlit variants for lower maintenance.
