Leadis Tech Announces Progress In Active Matrix OLED Display Strategy

October 16, 2007 by Jeff Shepard

Leadis Technology, Inc. announced that it has acquired intellectual property from Nuelight Corp. that will aid in the development of Active Matrix OLED (AMOLED) display drivers. The acquired technology is said to improve manufacturing yields by correcting non-uniform brightness without increasing backplane complexity and improving the lifetime of displays by correcting image sticking. With the use of Electrical Pixel correction algorithms, the patent-pending technology also enables the change of calibration of each pixel through the display driver.

Based in Santa Clara, California, Nuelight is a private company that has been engaged in the development of solutions for the shortcomings of Active Matrix OLED displays.

"This acquisition represents a major milestone in Leadis’ AMOLED strategy and will allow Leadis to offer our AMOLED customers leading display driver solutions," said Jose Arreola, General Manager of Display Driver Products. "AMOLED displays offer tremendous promise for higher quality displays in many high volume applications. Leadis intends to be a proponent and key leader of this display technology as we design it into our display driver products starting in 2008."

AMOLED Technology is said to offer key advantages of fast switching speeds, outstanding viewing angles, vivid colors, low power consumption and competitive costs. Adoption of AMOLED technology into high volume consumer markets has been hampered by major drawbacks such as poor manufacturing yields, image sticking, short life times, and differential color aging

The company expects AMOLED technology to capture significant market share in the competitive FPD market of small screens for mobile phones and portable digital audio players (MP3 players), car radios, digital cameras and high-resolution microdisplays for head-mounted displays. Such portable applications favor the high light output of AMOLEDs for readability in sunlight, and their low power drain.
