In November 2011, Absen unveiled its Series A upgrades led by A1688.

    With luminance of over 12,000 nit and power consumption as low as 8,000 nit products, the A1688 delivers high brightness, energy efficiency and durability thanks to Absen’s improved control and LED technology. The powerful LED display is also cost-effective, helping maximize benefits for customers. Absen has started mass production of the well-received device, and can deliver it within 7 days.
 

    In the past two years, high-brightness full-color outdoor LED displays have been greatly sought-after as the industry pacesetter. What makes Absen an industry leader? What sets Absen’s new-generation A1688 apart from rival products available in the market?
 

    I. Proprietary LED Light, the Core Part of an LED Display

    Underpinned by its ability to develop LED lights, Absen spearheaded the industry to use one BIN for one display and limit the display’s LED wavelength to 2.5nm and brightness ratio to 1:1.2 as a way to control the display’s brightness and color uniformity based on LED lights. This enables Absen to outshine competitors fundamentally.

    Moreover, Absen continues to enhance the brightness of LED light. For example, the brightness of its oval green LED light has improved to 3200mcd from 1250mcd in 2007. The display appears white when red, green and blue colors have a brightness ratio of close to 3:6:1, indicating that the green LED light contributes to 60% of the overall brightness in white balance. Display vendors have been plagued by low-luminance green LED lights in outdoor displays. In October 2011, Absen developed a high-brightness LED light that is 30-50% brighter than similar products in terms of red, green and blue brightness.

The following table compares LED lights from different producers:

    II. LED Light with Brightness of Up to 12,000 Nit

    Absen’s A1688 outdoor display has remained popular with customers for its stable quality and high cost-efficiency. In March 2010, Absen increased A1688’s brightness to 8,000 nit, making it one of Absen’s best sellers. In November 2011, Absen raised its brightness to a staggering 12,000 nit. Notably, Absen has achieved the milestones by using its own high-brightness LED lights without increasing the current.

    At 12,000-nit in full white mode, the A1688 operates on maximum currents of only 13.6 mA, 12.8 mA, and 11.4 mA for a single red, green and blue light respectively, far below the highest safe working current of 20mA for LED lights. As well as reducing the operating power, the low current level extends the display’s service life. You are also free to adjust the brightness according to conditions. 

    III. Enhanced Display Effects and Extended Service Life

    Customers can benefit from the improved brightness in the following ways:

    1. High-brightness display can perfectly present images even in direct sunlight. From the Middle East to Las Vegas and to anywhere else on the globe exposed to strong sunshine, Absen’s A1688 is poised to exceed your expectations for brightness.

    2. By making brightness free from the view distance, the A1688 can reach a wider audience. The farthest view distance of a display may vary with the pixel pitch, area, and length-breath ratio, and, more importantly, the brightness. Light attenuates while traveling in the air due to absorption and dispersion by air molecules and aerosol. Lambert Law reveals that light intensity attenuates exponentially as the propagation distance increases. Attenuation intensifies in smog or when the air quality is poor. LED displays must deliver adequate luminance to cover a long view distance.

    3. The A1688 delivers a significantly prolonged service life. Operating at 12,000 nit for two years, Absen’s A1688 can retain 8,000 nit, comparable to any mainstream display, thus increasing its durability. When running at 8,000 nit, the device helps significantly reduce LED light attenuation and equipment load, which in turn may prolong the display’s service life.

    4. The energy-efficient A1688 can save much for customers by increasing the brightness of LED light to cut the total power consumption.
