Planar LC640.480.33-AC manual Display Dimensions, Warm-up Characteristic

Warm-up Characteristic

Some time after startup is required to allow the CCFL tubes to reach their normal operating temperature. The graph in Figure 14 shows the typical room temperature warmup curve for the LC640.480.33-AC when set to maximum luminance. As can be seen, luminance is at nearly 95% of the final value after five minutes of operation, and 99% of the final value at 10 minutes after startup.

Display Dimensions

The recommended clearance shown in Figure 15 illustrates the distance behind the display ECA which should be left for free low of air for the purposes of convection cooling. In Figure 15, dimensions are in millimeters. Tolerances unless specified are as follows:

.x ±0.50

.xx ±0.25
