LED backlight manufacturers are still cautious market trend

LED, light-emitting diode, is widely used in various electronic products, as an indicator or light source. Now, LED by virtue of high brightness, wide color gamut, fast response and easy to separate switches and other characteristics, favored by the majority of manufacturers in the industry, is expected to become the next generation LCD backlight.

LED dot matrix backlight

At present, Samsung has launched a professional LCD XL20 with LED backlight, backlight design three RGB hybrid LED dot matrix, XL20 makes its color gamut value from 72% increase to 114%, provides a more realistic color display for the user. Many manufacturers have followed suit, but due to technical problems, but has not yet launched the finished model.

Many technical experts believe that, despite the LED thin, power-saving specific, there is great potential in the application of notebook panel. In addition, mercury free environmental protection theme, manufacturers will also use LED backlight source display equipment to promote. But for the general display equipment manufacturers, if the LED backlight technology used in large area backlight equipment, the cost and technical test will be a considerable problem.

Samsung XL20 uses RGB tricolor LED backlight design

In fact, whether it is RGB tricolor mixed light LED, or white LED backlight program, currently in practical applications, there are some deficiencies. From a technical point of view, LED dot matrix by the light itself is prone to uneven color, if the manufacturers do not pass, this phenomenon will be more serious than the cold cathode lamp (CCFL) backlight. In many of the world's display manufacturers, like Samsung, like the use of their own technology, effectively play the advantages of LED backlight manufacturers, it is less and less.

Editor's comment:

At this stage, only a few high-end professional grade LCD began using dot matrix LED as backlight. Among them, a variety of Samsung LED backlit LCD monitor has received a lot of praise from the industry. Apple began to "green apple" as its theme, its own LED backlit LCD display time, schedule.

From the overall point of view, LED backlight technology in the second half of 07, will be more value display device manufacturers. The technical strength and equipment manufacturers to display their own, whether it can solve the various problems of LED backlight technology, and backlight module manufacturers to change the R & D and production of LED backlight module, the time required will be important factors affecting LED backlight application rate.
