1, belongs to the field of science and technology The project belongs to the field of information technology and involves grayscale scanning methods for flat panel displays, design of application-specific integrated circuits and system implementation. 2. Main technological innovation content and characteristics Ultra-high gray level imaging technology refers to the imaging technology supporting 1024/4096/65536 gray level, which is one of the development trends of the new generation flat panel display. Aiming at the transmission bottleneck and frame rate control of high-gray scanning imaging data bandwidth in high-definition mode, and based on the needs of the relevant flat panel display industry, the project completed the deduction of the true restoration method for ultra-high gray imaging of flat panel displays (FPD) and the IP core. Design and implementation of dedicated chips and system solutions, the innovative content and characteristics are as follows: (1) Major innovations in key technologies: Three methods, fractal scanning, implanted recursive scanning, and spatio-temporal hybrid scanning, were originally proposed to solve the bottleneck problem of data transfer speed from flat panel display storage space to display medium space. A spatio-temporal mapping topology architecture for FPD gray scale scanning is constructed, and a subspace division strategy, an optimal scanning structure and theoretical model for FPD gray scale control are proposed. The problem of time redundancy in scanning imaging is effectively solved and high scanning utilization is achieved. Theoretical method with no brightness loss and high frame rate is achieved. According to the scientific and technological novelty search and level search reports of intelligence agencies, the method is novel and reaches the international advanced level. (2). The overall IP core and application specific integrated circuit (ASIC) technology have reached the international advanced level: the project targets LEDs, OLEDs, and TFTs_New flat panel displays such as LCD respectively adopt the theoretical principles of fractal, implantation and spatio-temporal hybrid scanning to build a circuit architecture of a scanning algorithm, complete the design of efficient scanning and driving key IP cores with independent intellectual property rights, and form a series of ultra-high-gray level FPD application-specific integrated circuit chips; approved by the Shanghai Science and Technology Achievements Appraisal Conference, it has reached the international advanced level. (3). System integration innovation: In the application of FPD systems, the project proposed a system architecture that integrates video image processing and transmission, image enhancement and scaling, scan timing control and display restoration units. The FDP system product has low performance characteristics such as delay, ultra-high gray scale (20-bit gray scale) and high refresh rate (3840Hz), high resolution and high modularity; According to the consultation report of the scientific and technological novelty search consulting department, its main technical indicators are novel and have reached the international advanced level. Since the launch of this project, a total of 81 patents of various types have been applied for and authorized; including 31 invention patent applications, 17 have been authorized, and 3 internationally authorized patents; 28 utility model patents have been authorized, 12 integrated circuit layout registrations, and 3 software copyrights; 7 design patents. Published 145 academic papers in domestic and foreign journals and international conferences, 83 of which were searched and included in SCI/EI; 2 monographs. 3. Application promotion The relevant technical achievements of this project have a high degree of transformation and have been successfully applied and promoted in Shanghai Sansi Electronic Engineering Co., Ltd., Shanghai Radio and Television Electronics, Shanghai Jingtian Company and other enterprises; during the period from 2010 to 2012, the project-related output value of Shanghai Sansi Company alone reached 2.645 billion yuan, profits and taxes were 317 million yuan, and foreign exchange earned from exports was 80.12 million US dollars, producing huge economic benefits; The project's technical achievements and products have been applied in Times Square in New York, the Beijing Olympics, and the Shanghai World Expo, achieving excellent social benefits.
