Less obvious but important distinctions
between LCD flat screen monitors and CRT monitors:
Health. The flicker
experienced on CRT screens which result from their need to be "redrawn"
frequently (known as the "refresh rate") can lead to eye strain and
headaches. LCDs, on the other hand, are basically flicker free. In addition, CRTs give off
radiation in the form of ELF and VLF, resulting in health concerns for
users and controversy in the industry.
Computer monitor energy and heat. LCDs are more energy efficient than CRTs and can
result in slight monetary energy savings over the course of a year. There is less
heat generated by LCDs so users experience less heat discomfort.
Cost of ownership: While acquisition costs are still higher for LCD
displays (though the price has been coming down), other costs may be
minimal compared to CRTs. As examples: LCD backlights last 2x as long as
CRTs and cost less to replace, and are able to be replaced in the field
without test equipment; while CRTs must be sent to the factory for testing
and replacement. The weight of CRTs increase their shipping costs.
Viewing angles. CRT
monitor screens allow viewing access from all angles - a definite
plus when you have people crowding around your desk to view something
(Though a definite security risk recognized by HIPAA regulations. Using
privacy filters helps provide
HIPAA compliance). LCD flat screen monitors, on the other hand, have a limited viewing area, so this screen
appears slightly washed out when viewed from "off-center;" this can be
problematic in group consultation situations.
Office ergonomics addresses the comfort,
safety, and organization of your work area and business tools.
With desks no longer dominated by
large CRT monitors, your work area is less crowded and you gain
additional work surface. Light-weight, LCD flat screen monitors can usually be easily
moved without straining. Or, you have an option of attaching them
to LCD monitor arms.
These ergonomic accessories provide easy positioning adjustment and elevate them
above the desk. Swing them out of the way when they're not in use.
