LJ64ZU51 Sharp 9.4"640×480 EL Industrial Display
Sharp LJ64ZU51 is a classic 9.4-inch VGA amber electroluminescent (EL) industrial-grade display launched by Sharp in 1992, adopting Sharp's exclusive Thin Film Electroluminescent (TFEL) technology, one of the most reliable solid-state display products in industrial display history. This product adopts a 4:3 standard square screen ratio design with native 640(RGB)×480 VGA resolution and 84PPI pixel density. It features 30cd/m² typical brightness and 80° full viewing angle display, zero flicker, making it less tiring for long-time viewing.
LJ64ZU51 adopts a solid-state self-luminous structure, no backlight required, with excellent vibration resistance, shock resistance and wide temperature operation capability, supporting an operating temperature range of -5°C to +55°C and a storage temperature range of -40°C to +80°C. The signal interface is a 26-pin parallel data interface with 5V (logic) / 24V (drive) dual power supply. The overall dimensions are 246(W)×180(H)×34(D) mm and the weight is about 700g. Although this model has been discontinued for many years, due to its excellent reliability and wide compatibility, it remains a core replacement component for old industrial equipment, medical instruments and military equipment, with stable original inventory supply worldwide.
