[. . . ] Do not touch the display electronics during operation. Cable Length A maximum cable length of 600 mm (24 in. ) is recommended. Longer cables may cause data transfer problems between the data transmitted and the display input connector. Excessive cable lengths can pick up unwanted EMI. Cleaning As with any glass or coated surface, care should be taken to minimize scratching. Disposable cleaning cloths are recommended to minimize the risk of inadvertently scratching the display with particles embedded in a re-used cloth. Particular care should be taken when cleaning displays with antiglare and anti-reflective films. 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. 4 EL240. 128. 45 Operations Manual (020-0345-00C) 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. The display operation is based on the symmetric, line-at-a-time data addressing scheme. Power The supply voltages are shown in Table 1. All internal high voltages are generated from the display supply voltage (VH). The logic supply voltage (VL) should be present whenever video input signals are applied. The minimum and maximum specifications in this manual should be met, without exception, to ensure the long-term reliability of the display. Performance characteristics are guaranteed when measured at 25 °C with rated input voltage unless otherwise specified. Planar does not recommend operation of the display outside these specifications.
