EL552.256-Q2 EL552.256-Q2 Display The EL552.256-Q2 thin film electroluminescent (EL) display is a highperformance alternative to lower resolution LCDs and VFDs and is the ideal solution in demanding applications where superior visual performance and environmental ruggedness are critical. The display consists of an EL glass panel and control electronics assembled into a space-saving, rugged package for easy mounting and a separate DC/DC converter with interconnecting cable. The EL552.
Mounting EL Displays Properly mounted, EL displays can withstand high shock loads as well as severe vibration found in demanding applications. However the glass panel used in an EL display will break if subjected to bending stresses, high impact, or excessive loads. CAUTION: To prevent injury in the event of glass breakage, the use of an impact resistant shield or a protective overlay should be used on the viewer side of the display. Stresses are often introduced when a display is mounted into a product.
EL552.256-Q2 Avoiding Burn-In As with other light emitting displays, displaying fixed patterns on the screen can cause burn-in, where luminance variations can be noticed. Use a screen saver or image inversion to avoid causing burn-in on the display. Specifications The EL panel is a matrix structure with column and row electrodes arranged in an X-Y formation. Light is emitted when an AC voltage of sufficient amplitude is applied at a row-column intersection.
VH is applied. The minimum and maximum specifications in Table 1 should be met, without exception, to ensure the long-term reliability of the display. The video inputs, shown in Table 2, pass from the video source to the display through the DC/DC converter. Table 1. Video Input Voltage Requirements Description Maximum input voltage Low-level input voltage High-level input voltage Low-level input current High-level input current (VIL) (VIH) (IIL) (IIH) Output high voltage (@ Ioh=0.
EL552.256-Q2 DC/DC Converter (Power Supply) The display comes with the PS512-6, which is an efficient multiple-output DC-toDC switching power supply assembly. The power supply provides the unique voltage requirements for EL displays. Its input voltages are +12V only or both +12V and +5V. EXT. INT. A square-pin jumper (J4) is provided to select between these two input configurations and is in the +5V position when the product is shipped.
