Introduction to Projectors
The opaque projector shone bright light onto a non-transparent object and a combination of mirrors or lenses projected the image onto a screen. As more light was required than with an overhead projector, the projected materials could be damaged, thus limiting the use of the device.
According to Henry Petroski in "Success through Failure: The Paradox of Design," the police and the army used an early version of the overhead projector in the 1940s. These first machines used already-existing slide projector technology to project images onto a large screen.
While 3M liked the idea and developed it into the first overhead projector, the idea lacked support in the marketplace. Nevertheless. Appledorn approached teachers, who realized its potential in the classrooms and soon enough, the product began to record substantial sales.
3M and Buhl Industries were among the first major manufacturers of overhead projectors.
In the 1980s, teachers started using overhead projectors to project moving images using LCD screens. The first such projectors were monochrome, but color versions started to be available by the end of the 1980s.
PMA has dubbed 2010 “The Year of the Projector” because numerous supply-side product innovations, combined with rapid growth in demand in developing countries, have breathed new life into what had become a mature industry with single-digit growth rates.
“Innovations such as 3-D-ready ultrashort-throw models, built-in interactivity, PC-free presentations, and LED or laser illumination are responding to user needs, and in some cases expanding the lists of applications or buyer types for which projectors can be used,” said Dr. William Coggshall, president of PMA. “.. countries in MEA [Middle East and Africa], Latin America, the ASEAN [Association of Southeast Asian Nations] countries and China are growing at rates outpacing those in the historically larger markets, often due to major national programs for education.”
Although it is not the largest category within the overall projector market, the New Era (sub-500 lumen) category is the fastest-growing one and is expected to grow from 512,000 units in 2009 to 1.1 million in 2010.
“The two sweet spots in this category are the tiny battery-powered pico projectors currently offering a maximum brightness of 50 lumens, and their larger wall-powered personal projector siblings,” Coggshall said. “During 2010, we expect the pico projectors to account for roughly three times as many units as the personal projectors.”
