TOKYO—Convincing consumers to trade in bulky old-school televisions for slim, high-definition models was a huge success story for the TV industry. Now manufacturers are angling to kick off another buying spree.
They are gearing up to promote what the industry calls "ultra high-definition" televisions, or UHDTVs, which promise four times the resolution of existing TVs and are likely to be a hot topic at next week's Consumer Electronics Show in Las Vegas.
Such TVs create images using more than eight million pixels, compared with about two million pixels of today's full high-definition televisions. At the moment, however, a major obstacle stands between consumers and sharper pictures: price.
The stratospheric price tags—often the case with new technology—don't worry some industry watchers, who recall that HDTV sets, cellphones and other products were initially out of reach of most consumers but became hits as prices declined.
