Proceedings Article | 26 April 2002 Paper

Changing scenarios in the projection market

Sweta Dash

Proceedings Volume 4657, (2002) https://doi.org/10.1117/12.463791

KEYWORDS: Projection systems, LCDs, Digital Light Processing, CRTs, Liquid crystal on silicon, Televisions, Manufacturing, Video, Lamps, Computing systems

The projection market is undergoing many dynamic changes. Front LCD and front-reflective (mainly DLP) technologies compete with each other for most projection applications. The front-projector market is still emerging, with new technologies (such as liquid-crystal-on-silicon, or LCOS), new product categories developing (like <EQ3-pound projectors), and new suppliers entering the market. In the rear-projection market, although rear CRT remains the dominant force in large TV applications, new products based on rear DLP, LCD, and LCOS will take more market share from rear-CRT technology. This paper analyzes changing scenarios in the projection market by examining the developments over last five years. Also, this paper touches on what to expect in the next five years.

Market trends in the projection display industry

Sweta Dash

Proceedings Volume 4294, (2001) https://doi.org/10.1117/12.420776

KEYWORDS: Projection systems, LCDs, Digital Light Processing, CRTs, Liquid crystal on silicon, Televisions, Image segmentation, Manufacturing, Lamps, Light valves

Read Abstract +

The projection display industry represents a multibillion- dollar market that includes four distinct technologies. High-volume consumer products and high-value business products drive the market, with different technologies being used in different application markets. The consumer market is dominated by rear CRT technology, especially in the projection TV segment. Rear LCD (liquid crystal display), MEMS/DLP (or Digital Light Processing ^TM) and LCOS (Liquid-crystal-on-silicon) TVs are slowly emerging as future competitors to rear CRT projectors. Front CRT projectors are also facing challenges from LCD and DLP technology for the home theater market while the business market is completely dominated by front LCD and DLP technology. Three-chip DLP projectors have replaced liquid crystal light valves in large venue applications where projectors have higher light output requirements. In recent years front LCD and LCOS projectors have been increasingly competing with 3-chip DLP projectors especially at the low end of the large venue application market. Within the next five years the projection market will experience very fast growth. Sales and presentation applications, which are the fastest growing applications in the business market, will continue to be the major driving force for the growth for front projectors, and the shift in the consumer market to digital and HDTV products will drive the rear projection market.

Market trends in the projection display industry

Sweta Dash

Proceedings Volume 3954, (2000) https://doi.org/10.1117/12.383360

The projection display industry represents a multibillion- dollar market that includes four distinct technologies. High-volume consumer products and high-value business products drive the market, with different technologies being used in different application markets. The consumer market is dominated by rear CRT technology, especially in the projection television segment. But rear LCD (liquid crystal display) and rear reflective (DLP, or Digital Light Processing^TM) televisions are slowly emerging as future competitors to rear CRT projectors. Front CRT projectors are still popular in the high-end home theater market. Front LCD technology and front DLP technology dominate the business market. Traditional light valve technology was the only solution for applications requiring high light outputs, but new three-chip DLP projectors meet the higher light output requirements at a lower price. In the last few years the strongest growth has been in the business market for multimedia presentation applications. This growth was due to the continued increase in display pixel formats, the continued reduction in projector weight, and the improved price/performance ratio. The projection display market will grow at a significant rate during the next five years, driven by the growth in ultraportable (< 10 pound) projectors and the shift in the consumer market to digital and HDTV products.
