BOE has been committing to the promotion and popularization of 8K display technology. In recent years, it has successively exhibited 65 '/ 75' / 98 / 110 '8K TV or panel technology on Sid [1]. Nowadays, most of these technologies have been introduced into mass production, and some have been developed into formal products. The system introduced in this paper has been applied to the 8K broadcast monitor products. It can directly receive 4 channels of 12G-SDI signals of 8K camera as input, and embed IP such as gamut conversion, Up-Scaler, RGB Processor, Gamma Curve Adaptation, etc. Finally, the display effect of signals from different color gamut and different standards (SDR, BT.1886, HLG, PQ, etc.) is correctly displayed on it.

Mini‐LED Backlight Units can reduce the light mixing distance and the number of backlight blocks, making the monitors lighter and thinner, achieving higher contrast and better effects. As a leading company in the panel display industry, BOE has been developing Mini‐LED technology since 2016, and has developed 65', 75', and 86' smart commercial display monitors based on Mini‐LED technology.This paper verifies the Local Dimming technology with multiple partitions using FPGA, it's safe to say that it obtains a finer light distribution and less halo effect, which will strongly support MiniLED display products in the future.

Picture quality calibration technology plays an important role in the display system. The focus of the radio and television system is to obtain the best visual experience, and many of them include beautifying images and pleasing the audience. And the focus of the professional monitor system is to restore the live effects of the camera and other film sources to the greatest extent. This paper introduces the image quality calibration technology in the monitor system, mainly around the color temperature, gamma and color gamut calibration technology, and realizes the automatic calibration process. This method has been successfully applied to the image quality calibration work of monitor products. It liberates human resources, significantly improves the efficiency of R&D and testing of monitor products, and greatly promotes the mass production of monitor products.

BOE 4K‐UHD (Ultra‐High‐Definition, 3840x2160) 3D display processing system based on FPGA (Field Programmable Gate Array) technology, realizes receiving, processing and transmitting of 4K 3D video. In details, 4K 3D video processing functions including interlacing, deinterlacing, stretching, frame rate conversion, mirror image, depth of field adjustment, 2D/3D switching and so on, can be used in the 4K 3D display system. The display system takes advantages of parallel processing architecture based on FPGA device to enhance the ability and efficiency of processing high resolution image, increase the system throughput, which can reach up to 16Gbps, and reduce the system delay, the minimum of which can be within 10ms. Besides, the mainstream video interface protocols including SD/HD/3G‐SDI, DisplayPort 1.2, DVI, are realized in FPGA device without the additional protocol conversion chips. This saves space and power. Additionally, the display system supports various 3D formats, including Side‐by‐Side, Line‐by‐Line, and Dual‐Link. This paper will give a detailed description of the system architecture and key technologies of the display system.
