Resumen del manual
The EL320.240-FA3 utilizes Planar’s proprietary Integral Contrast Enhancement technology combined with red and green filters patterned over Planar’s industry-leading yellow phosphor to achieve unparalleled image quality in hues of red, green and yellow. Three intensity levels in each of the red and green sub-pixels generate sixteen distinct colors (nine chromatically different colors, black, and two mid-levels of red, green, and yellow.) The display consists of a solid state EL glass panel, depicted below, with a124mm diagonal active area, and control electronics assembled into a space-saving, rugged package for easy mounting. Features and Benefits • Excellent visual performance: Unparalleled crisp, clear image Excellent contrast Unbeatable viewing angle of > 160° for all colors in all directions No off-axis color or contrast shift • Extremely wide operation temperature range: -50 to 85C • Instant turn on at -50C: no heaters needed, no warm up time • Long life phosphor: allows >11 years of continuous operation • Wide dimming range via digital control and analog voltage input • Rugged solid state construction • Great reliability: MTBF > 50,000 hours demonstrated • Low cost of ownership: no maintenance, no lamps to replace • AMLCD-type panel interface, 3V and 5V logic compatible • RoHS compliance Installation and Set-up Do not drop, bend, or flex the display. Do not allow objects to strike the surface of the display. CAUTION: The display uses CMOS and devices. These components are electrostatic-sensitive. Unpack, assemble, and examine this assembly in a static-controlled area only. When shipping, use packing materials designed for protection of electrostatic-sensitive components. 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. Avoid bending the display. Stresses are often introduced when a display is mounted into a product. Ideally, the mounting tabs of the display should be the only point of contact with the system. Use a spacer or boss for support; failure to do so will bend the display and cause the glass to break. The instrument enclosure or frame should not flex or distort in such a way that during use the bending loads might be transferred to the display. The EL320.240-FA3 mounting tabs were designed for a 3 mm screw. Mounting surfaces should be flat to within ±0.6 mm (±0.025"). Use all the mounting holes provided. Failure to do so will impair the shock and vibration resistance of the final installation. WARNING: These products generate voltages capable of causing personal injury (high voltage up to 140 Vac ). Do not touch the display electronics during operation. Cable Length A cable length of 0.5 m (20 inches) or less is recommended. Longer cables may cause visual artifacts such as pixel “jitter” due to data transfer problems between the host and the display. Cleaning As with any glass surface, care should be taken to minimize scratching. Clean the display glass with mild, water-based detergents only. Apply the cleaner sparingly to a soft cloth, then wipe the display. Disposable cleaning cloths are recommended to minimize the risk of inadvertently scratching the display with particles embedded in a re-used cloth. Avoiding Image Burn-In As with other light emitting displays, displaying fixed patterns on the screen may cause burn-in, where luminance variations can be noticed after hundreds of hours of operation. To avoid image burn-in, use a screen saver or use periodic image inversion if possible. Note that the rate of image burn-in will slow over time such that most of the burned-in image effect occurs in the first 1000 hours of operation. Power Supply and Video Sequencing Any combination or sequencing in the application or removal of VH (12VDC input power)and/or video signals will not result in abnormal display operation or display failure. VH Overcurrent Protection There is no overcurrent protection on VH, the 12V power input. To protect against catastrophic faults, Planar recommends the use of a fuse or similar protection on the VH input to the display. Internal Frame Buffer This display includes an internal frame buffer, which is required to transform the incoming video data into the desired displayed data. The display frame rate (the rate at which the phosphor is scanned) and thus the display brightness are independent of the frame rate of the user-supplied input data. Video data need not be continuously sent to the display since previously sent data is stored indefinitely until new data is received. CAUTION: Some third-party video controllers use frame dithering algorithms to produce gray scale images. If such algorithms are used, the internal frame buffer may cause objectionable visual artifacts. Color Bit Mapping The EL320.240-FA3 utilizes standard AMLCD-type video interface tim...
