Su Daguang Electric Schools realize efficient and stable Micro LED driving circuit technology breakthrough

Micro-LED, also known as micro-luminous diode, has the advantages of high resolution, low power consumption, high brightness, high contrast, fast response speed, long life and other advantages, so it has become a key core device for the new generation of display technology. The National Development and Reform Commission, the Ministry of Science and Technology, the Ministry of Industry and Information Technology, and the Ministry of Finance have successively issued relevant support policies that support new display technology research and applications. Many display companies are increasing the research and development of Micro-LED display technology.

For Micro-LED, it usually requires a high voltage to complete the driver of the Micro-LED chip, and the high-density Micro-LED chip integration will cause the power consumption of the display panel to increase sharply, bring reliability problems, affect actual products The performance of the application -driven circuit is a key part of restricting its industrial application.

Recently, for the pain points of the industry, the students of the School of Optoelectronics and Engineering of Suzhou University have developed an efficient and stable Micro-LED display driving circuit in the team's many years of technical accumulation. Through no equivalent pulse width gray gray modulation strategy, the Micro-LED pixel unit of Micro-LED pixel units is achieved at a limited frame rate, which improves the uniformity of brightness in Micro-LED; Manufacturing technology has effectively improved Micro-LED luminous efficiency; through the new threshold voltage compensation scheme, the driving current error effectively reduces the demand for stable display at high frame rates. The team related scientific research results were published in the international top journals in the field of photoelectric and have obtained a number of authorized invention patents. In the future, this result is expected to achieve large -scale applications in wearable/consumer electronics, digital high -definition display, car display, virtual/augmented reality and other different application scenarios.
