Hefei's 55 billion 8.6-generation OLED project has made new progress​

On March 10, according to Da Wan News, Hefei Guoxian's 8.6th generation AMOLED production line project has completed more than 35,000 pile foundation operations and has entered the main plant construction phase. In addition, the construction of civil engineering project B project housing, integrated power station and other projects were recently awarded to Shanghai Baoye, and the relevant construction units have entered the site for construction.
​

It is reported that the total investment of Hefei Guoxian's 8.6th generation flexible AMOLED production line project is 55 billion yuan, with a designed production capacity of 32,000 glass substrates (size 2290mm×2620mm) per month, and construction will start in September 2024. The production line is funded by Visionox and Hefei Investment Platform, and Hefei Guoxian (a subsidiary of Visionox) is responsible for the investment, construction and operation of the production line.

As the world's first 8.6-generation AMOLED production line that adopts FMM-free (fine metal mask) technology (i.e. ViP technology), its products cover medium-sized application areas such as tablets, laptops, and automotive displays.

Visionox said that ViP technology can significantly improve the performance of AMOLED products, increasing the effective light-emitting area (aperture ratio) of AMOLED from the traditional 29% to 69%, and increasing the pixel density to more than 1,700 ppi. Combined with Tandem stacking device technology, it can achieve 6 times the device life or 4 times the brightness compared to FMM AMOLED.

Vibration-resistant full-field heterodyne long-arm interferometry.​

​

Abstract​

Long-distance surface profiling requires a high level of vibration resistance. Here, we propose a heterodyne interferometry scheme that uses two acousto-optic modulators (AOMs) to achieve precise and high-speed heterodyne phase-shifting frequencies. This solution offers high spatial resolution and effective vibration resistance. We measured the fundamental vibration conditions in the laboratory and simulated the effect of vibration on measurement repeatability across different difference frequencies. Experiments have demonstrated that this method can produce a single 3200 Hz sampling of a 1024 pixel × 1024 pixel camera within a period of 1.25 ms. The repeatability of measurements at 22 m away is better than 0.8‰ wave root mean square (RMS).​

Changchun Institute of Optics, Fine Mechanics and Physics optimizes and fabricates high-brightness HiBBEE inhomogeneous waveguide semiconductor laser

High-brightness semiconductor lasers have extremely important applications in fields such as laser radar. Traditional semiconductor lasers face difficulties such as large vertical divergence angle, elliptical beam output, multiple lateral modes, and poor beam quality, which limit the direct application of high-brightness semiconductor lasers.

To address this problem, the team of the Bimberg Sino-German Green Photonics Research Center of the Changchun Institute of Optics, Fine Mechanics and Physics adopted a high-brightness vertical wide-area edge emission (HiBBEE) structure in the vertical direction, using the photonic bandgap effect to replace the traditional total reflection principle to limit the light field, increase the size of the light mode, and reduce the vertical divergence angle of the semiconductor laser; at the same time, in the lateral direction, a non-uniform waveguide was used to suppress the lateral high-order mode, improve the lateral beam quality of the semiconductor laser, and optimize the design and prepare the HiBBEE non-uniform waveguide semiconductor laser . The vertical and lateral divergence angles are still as low as 8.6° and 5.1° at a current of 1.5A, and the fundamental mode output is maintained, with a brightness that is 1.5 times higher than that of similar devices.

This high-brightness HiBBEE inhomogeneous waveguide semiconductor laser can significantly reduce the application cost of semiconductor lasers and has broad application prospects.
