Surface-conduction electron-emitter display commonly known as SED is a technology which is used while making different flat display panel such as electronic visual displays. SED’s make use of electron emitters with a nanoscopic-scale to boost colored crystals of phosphors and to develop an image.
SED consists of small cathode ray tubes (CRT’s) and each CRT is used to develop a sub-pixel on the display screen and then it is assembled in a group of three to make RGB pixels. Surface-conduction electron-emitter displays pool the advantages of cathode ray tubes, namely their wide viewing angles, high contrast ratios and quick response times. In addition these tubes have much lower power consumption rate than an LCD screens of the similar size.
There is a significant increase in the SED market because of the various advantages associated with the technology such as cathode ray tubes-matching black levels, contrast potential and excellent color, comparatively low-cost production and wide viewing angle. The market is having huge opportunities as a result of increased adoption and growing investment in the display panel sector.
The key drivers of this market include increasing focus on enhancing productivity of the display panels, increasing need for energy conservation and growing usage of display screen products such as TV, mobile and laptops among others, which are biggest revenue generator for the market. However, unknown life expectancy of SED’s is expected to inhibit the growth of this market.
The surface-conduction electron-emitter display market can be segmented by end-use applications into television, cameras (digital and video), mobile and healthcare devices display screen. The market can also be segmented geographically into North America, APAC, Europe and RoW regions. Some of the key players in the embedded system market are Canon Corporation, Toshiba Corporation and Sony Corporation among others.
