在消费者的印象里,背投电视一直都是外形巨大、画面亮度有限的CRT显像管背投的形象,近一两年来,外形轻薄很多,亮度也高得多的两种新型背投电视逐渐在市场上崛起,它们就是LCD液晶背投和DLP光显背投,由于两者的显像核心LCD板和DMD芯片都如芯片一般小型化,相对使用CRT显像管作为显示核心的背投而言,它们被统称为芯片式背投。两种背投电视的工作原理我们在以前的杂志里都分别作过介绍,它们比起CRT显像管背投,具有数字化程度高、占地较小、使用调试方便的明显优势,在价格上也逐渐接近大众消费水平。临近元旦和春节消费旺季,《电器评介》评测室专门组织了多款芯片式背投电视的对比评测,本期杂志先期推出6款LCD液晶背投的对比评测,2005年2月号上面我们将推出多款DLP光显背投的对比评测,敬请留意。
In the minds of consumers, rear projection televisions have always been the image of a CRT CRT rear projection with a large size and limited screen brightness. In the past year or two, the two new rear projection TVs, which are slimmer and lighter, Rise in the market, they are the LCD rear projection LCD and DLP optical rear projection, the two core imaging LCD and DMD chip chips are generally smaller, compared to the CRT CRT as the core of the rear projection, they Be collectively referred to as the chip rear projection. The working principle of the two kinds of rear projection TV We have introduced in the previous magazines, they CRT rear projection than the CRT, with a high degree of digital, small footprint, easy to use debugging obvious advantages in price gradually Close to the mass consumer level. Adjacent to the New Year and Spring Festival consumer season, “Electrical Review” evaluation room specifically organized a variety of chip-type rear projection TV comparison test, this issue of the magazine launched 6 LCD LCD rear projection comparison, February 2005 above we will Launched a variety of contrast evaluation of DLP light display rear projection, please note.
