DREAM

That the one piece of equipment I dream of is an ideal LCD display should not be a surprise. It is what I have been most concerned with of late. And it is also what I look at most to see my photographic images.

However what I dream of is not some exotic, superior new level of device performance at all, but one that is inexpensive and is based on already existing technologies that could be put into a very affordable LCD display. In other words I am dreaming about something that would work well for anyone using a computer to do digital photography editing and processing.

Why such a display is not on the market presently is in part because customers have not demanded it, mostly because they are not that aware of what they need, nor are they aware of what the contemporary industry could produce. Another reason is that the graphics computing aspect of the technology industry is a mix of unrelated items, much of which is controlled by sometimes different, alien and contrary items. LCD displays are not made by companies that make computers. They are made by companies whose largest market is the home television and similar kinds of display devices that have no dependence on computers to function. So LCD displays for computers are just slightly modified TV displays, and what works best for computer users is very likely unknown to the scientists and engineers who create the LCD displays.

So, exactly what do I have in mind? It would be an LCD display like many now seen in stores that sell computers. It wold be the largest size that sells at competitive, affordable prices with a 22 inch diagonal in HD format with a 1920 by 1050 resolution. It would be different in some very important senses, first that the maximum white luminance brightness would be half of the usual 250-300 CD/M2 that is currently popular. This would be accomplished by reducing the brightness of the backlight. The backlight source would be white LED lamps, because they are efficient, uses less energy and remain consistent for a longer period of time. The color gamut would be slightly greater than 90% of the size of the Adobe RGB (1998) color profile, a feature that is not uncommon today and has been offered in a lower-cost affordable brand of LCD displays recently.

What would be most different is that there would only be one control with two settings, a bright setting that would provide a white luminance of 120.0 to 140.0 CD/m2 and would be intended for normal office/home computing use. The second setting would be a lower brightness with a white luminance of 90.0 CD/m2 for digital photography image editing and processing. At this setting the standard parameters for computer video would be applied of color temperature of 6500K and a gamma of 2.2. But in addition the display would be factory calibrated and profiled to achieve a neutral gray, and both the calibration file and profile would be fed to the computer through the DDC channel of the DVI interface connection.

In other words this LCD display would do well both for most home/office computing and by simply click of a switch to the “photo” setting would provide a consistent, reliable adjusted, calibrated and profiled parameter for color managed digital photography editing and processing.

I believe with an LED backlight lowered to half of the present LCD display level using the LED source the “photo” setting calibration and profile would remain sufficiently stable and within a range that would be effective for all serious digital photography needs for an extended use period. The display would be “self” adjusted, calibrated and profiled to be effective in a color managed image computing environment without requiring any user adjustment, sensor testing and profiling, or any additional expense.

I would particularly like to see Apple Computer make such an auto profiled LCD display available for both Apple computers and PC Windows computers as well, it could be another Apple sales success. But more important, combined with the Apple Mac Mini it would be an ideal digital photography computer setup many users could both afford and enjoy the best digital photography editing and processing experience.
