LED backlight source is developing towards ultra-thin

(1) LED thinning, high power and light guide plate thinning

According to the forecast of DisplaySearch, a market research organization, the global sales of LED LCD TVs in 2009 was about 4.09 million units, accounting for only 3% of the entire flat-panel TV market, but by 2014, the sales volume will soar to more than 123 million units, accounting for the entire flat-panel TV market. The share also soared to 53%.

LED color TV is not essentially a new display technology, but the application of new LED light source technology to replace the traditional cold cathode fluorescent lamp. However, this kind of LCD TV with side-type LED backlight has a slim body that is incomparable with traditional products: at present, the thickness of LED TVs produced by most famous manufacturers is about 2cm, which is unmatched by traditional LCD TVs. of.

The main competition of LED TVs is not only thickness, but also more economical and energy-saving power consumption and better picture quality. The technical performance advantages in many aspects are the core reasons for the rapid growth of the LED TV market.

(2) Borderless

Although LCD TVs can't really achieve "borderless" - this is just an exaggerated description of ultra-narrow bezels. However, industry experts have predicted that borderless products will become another peak in LCD TV process design after LED ultra-thin.

In fact, as early as three years ago, many LCD companies including Samsung have invested in the research and development of products with ultra-narrow bezels. However, these technologies are mainly used in the field of engineering display, such as LCD TV splicing walls. In April of this year, the narrowest frame thickness of an LCD video wall product launched by Samsung in the domestic market was less than 3mm. Since then, companies including Sharp, LG, and Taiwan's Chi Mei have also successively launched LCD panels that can meet the thickness of millimeter-level frames. , for the whole machine enterprise to choose. The support of many upstream manufacturers, on the one hand, shows the actual value of borderless technology, and on the other hand, it shows that the technical bottleneck of making LCD TVs with millimeter-level or even smaller-level borders has basically been broken.
