Korean and Japanese companies eager to promote OLED products of led street light standards?

It seems that everything for the development of China from high-generation flat panel industry. The tragic reality of the panel market prices continue to decline, led street light standards, the panel ofJapanese and Korean giants Samsung and LG LED wind began to bluster.

” LED TV in 2012 to enter the market is basically a foregone conclusion.” Flat-panelresearch institutions consulting, research director of group of Chi Li Yaqin, Samsung, LED high bay LGand Sharp has made ​​it clear that the CES show in January next year will display their LED TV products, but the LG also made ​​it clear that LED TV will be put into operationin the fourth quarter of next year, “all the signs show that 2012 will be the first year of  LED TV.

The LED panel is following the third generation after the LCD panel display technology.LCD, led street light standards, plasma and other second-generation technology compared to the advantages of LED technology is ultra-slim size, the thinnest to 0.005 cm the collapsible curl on agood substrate flexibility, color display significantly higher them as an alternative to thenew technology of the LCD panel LCD, Samsung, led street light standards, Sony and other Japanese and Koreanconsumer electronics giant.

In June this year, Samsung Mobile announced the 8th generation of AM-OLED panel test line will be put into use in May next year, you can cut 46 inches 55 inches and other large-size OLED panels, Samsung plans to field of use of the OLED panel from smart phones, tablet The computer extends to television and other fields. The next August, LG also saidit will invest $ 2.83 billion to build 8th generation OLED panel projects.

However, when the news show time Samsung and LG8, on behalf of the OLED panelmass production in 2014. Why just a few months time, led street light standards, Japan and South Korea panelOLED TV giant wind will be accelerated so?

How to control and improve the led street light standards

How to control and improve the quality of full color LED display? What is the important indicator reflecting the quality of the full color LED display LED? led street light standards. The first LED devices asthe most critical components of the full-color LED display for three reasons:

First of all, LED full color machine used in the largest number of devices per square meter will be used only a few thousand to tens of thousands of LEDs;

Secondly, the LED is to determine the main body of the optical display performance ofthe entire screen, led street light standards. a direct impact on the evaluation of the audience on the screen;

Once again, the LED display the overall cost to the proportion of the largest, ranging from30% to 70%. LED choice determines the quality of more than 50% of the entire display. LED high bay. If not other parts of the good LED, display, even the best can not make up the displayquality defects.

Reflect the quality of the full color LED display LED indicators are:

First, the failure rate

The full-color display by the tens of thousands or even hundreds of thousands of clusters of red, green, led street light standards. blue LED composed of primitive composition of any one color of LEDfailure will affect the display of the overall visual effect. In general, industry experience inthe LED display assembly to the aging failure rate in the 72 hours before shipping shouldbe no higher than three ten thousandths (LED device itself causes the failure).

Second, the antistatic ability

LEDs are semiconductor devices sensitive to static electricity can easily cause staticfailure,led street light standards.  antistatic ability is critical to the life of the display. In general, LED body staticmode test failure voltage should not be less than 2000V.

Third, the attenuation characteristics

Red, led street light standards. green and blue LEDs With the increase in working hours, the light attenuationcharacteristics. The pros and cons of the LED chip, The quality of the auxiliary materialsand packaging technology standards determines the level of the decay rate of the LED.In general, the light test of 1000 hours, 20 mA at room temperature, the attenuation of thered LED should be less than 10%, blue, led street light standards. green LED attenuation should be less than 15%.Consistent attenuation of red, green, blue, full-color LED display white balance impact,thereby affecting the display fidelity.
