研究目的
To develop an 85-inch 8K4K 120Hz LCD panel with BCE-IGZO structure and GOA design for high-end display markets.
研究成果
The prototype successfully combines BCE-IGZO with GOA technology to achieve super-size, high resolution (8K4K), and high refresh rates (120Hz). Future work includes lowering power consumption and improving optical performance.
研究不足
The development faced challenges such as the need for exposed stitching due to big size, lack of experience with IGZO GOA in 8.5 generation production line, and the need to decrease RC loading and increase charging time.
1：Experimental Design and Method Selection:
The project team developed a large size (85-inch), high resolution (8K4K), high refresh rates (120Hz) LCD monitor using BCE structure of the IGZO and GOA technology.
2：Sample Selection and Data Sources:
The prototype was demonstrated at the CHINA HI-TECH FAIR.
3：List of Experimental Equipment and Materials:
The panel uses P2P interface for data signal transmission, gate/source dual-driving method, and gate double scan.
4：Experimental Procedures and Operational Workflow:
The GOA circuit drives the middle gate line, scanning the whole panel from middle to two sides simultaneously.
5：Data Analysis Methods:
The prototype's performance was evaluated based on its resolution, refresh rate, and color gamut.
