Signal Scaling: It adjusts the input signal resolution to match the resolution of the LED screen. For example, if a 4K signal is fed to a screen with a different native resolution, the processor will scale it appropriately. Color Calibration and Correction: Video processors often include tools for color correction to ensure that the colors displayed on the LED screen match the intended output, accounting for any discrepancies in the LED panels’ color reproduction. Image Enhancement: They improve the visual quality by adjusting brightness, contrast, sharpness, and other image settings to make the picture look more vibrant and clear. Edge Blending: For large or curved displays made up of multiple LED panels, processors can blend the edges of each panel so that the transition between panels is seamless, eliminating visible lines or "joints." Frame Synchronization: It ensures that the input signal is synchronized with the LED display’s refresh rate to avoid issues like screen tearing or stuttering. Video Wall Management: In the case of multi-screen video walls, a video processor manages the distribution of the content across all screens, ensuring proper alignment, scaling, and synchronization. Input and Output Flexibility: Modern video processors come with multiple inputs (HDMI, DisplayPort, SDI, DVI, etc.) and outputs for compatibility with various sources and LED screen types. Video Signal Conversion: Converting between different types of video signals (e.g., from analog to digital) and ensuring the display can handle different formats, frame rates, and resolutions. Video Format and Aspect Ratio Handling: The processor manages and adjusts various video formats and aspect ratios to ensure the content fits properly on the LED display without distortion or cropping. Basic Video Processors: Used for small-scale applications like single LED displays or basic content delivery, often providing simple scaling and color correction. Advanced Video Processors: These are designed for large-scale, high-performance LED installations (such as digital signage, control rooms, or live events). They offer features like 4K/8K resolution support, advanced color calibration, and multi-channel input/output. LED Video Wall Processors: Tailored for large LED video walls, these processors manage complex content, control panel configurations, and allow for the flexible distribution of content across multiple screens. Novastar: Known for its powerful processors that are commonly used in large-scale LED screens, providing tools for scaling, color calibration, and signal management. Linsn: Specializes in LED display solutions, including video processors for high-end applications like video walls and stadium screens. Datapath: Offers advanced video processing solutions for professional-grade LED walls, including high-end video and graphics cards. Colorlight: Known for both hardware and software solutions that include LED display control systems, processors, and scalers. Barco: Provides high-performance processors often used in professional AV applications, with a focus on video wall management and color accuracy. Kramer: Offers a wide range of video processors for different types of installations, from small to large-scale LED screens.

Internet giants cling to AI chip entry point Ali has invested in five AI chip companies
In the era of personal computers and mobile phones, the chip industry remains largely dominated by giants like Intel, Qualcomm, MediaTek, and Samsung. However, with the arrival of the AI era, new opportunities are emerging for the mainland chip industry. Rising stars in the AI chip sector are gaining attention, and even major internet companies like Alibaba have made significant moves. In the past three months alone, Alibaba has invested in three AI chip startups, bringing its total number of AI chip investments to five, signaling a strategic buildup in this field.
Recently, Qualcomm Ventures announced investments in nine innovative companies across artificial intelligence algorithms, chips, and IoT sectors. While Qualcomm is actively involved, it’s not the sole leader. Intel, another semiconductor giant, is also making strides in investing in mainland AI and UAV-related industries. Among these investments, Shangtang Technology, Mobike, and Kneron (an AI chip company) have been highlighted, showing a growing interest in AI-driven technologies.
Notably, Alibaba’s Entrepreneur Fund is the main investor in many of these deals, marking its third AI chip investment in just three months. This follows earlier investments in Cambrian and Shenjian Technology, both led by Ant Group. The trend reflects a broader movement among tech giants to secure a foothold in the AI chip market.
Internet companies are increasingly focusing on AI chips as key entry points. Many leading AI chip firms were established between 2014 and 2016, and by 2017, the market began to take notice, with significant capital flowing into the sector. These companies have attracted large funding rounds, driven by the need for specialized AI chips that power various applications, from smartphones to smart homes, security systems, and autonomous vehicles.
The demand for AI chips is expected to grow rapidly, especially as more devices integrate AI capabilities. Smart audio devices, robots, and other AI-powered tools are becoming central to the future of technology. As a result, major tech companies like Alibaba, Huawei, Tencent, Baidu, and Lenovo are all accelerating their efforts to develop or invest in AI chip technologies.
At the recent Yunqi Conference, Alibaba launched the “Dharma Institute†and announced the “New Technology Strategy,†focusing on core technologies such as machine learning, chips, IoT, operating systems, and biometrics. Alibaba's CTO, Zhang Jianfeng, mentioned that an AI chip developed by the company will soon be available, enhancing cloud services with greater stability, control, and efficiency. For Alibaba, AI chips have become a strategic asset.
From an industry perspective, creating AI chips presents two major challenges: high capital requirements and the need for sufficient real-world applications. Startups often struggle with both, making external investment crucial. Alibaba, with its strong cloud computing infrastructure, diverse application scenarios, and extensive e-commerce resources, is well-positioned to support AI chip innovation.
Moreover, Alibaba Cloud generates massive amounts of user data, which serves as valuable training material for AI models. This data demands powerful, energy-efficient, and compact AI chips to meet operational needs. By investing in multiple AI chip companies, Alibaba is building a comprehensive ecosystem that supports its long-term vision in artificial intelligence.
Alibaba has already invested in five AI chip companies over the past two years. These include Hangzhou Zhongtianwei, which focuses on low-power and secure IoT solutions; Cambrian, targeting high-performance computing in mobile and data centers; Shenjian Technology, focused on security applications; and Kneron, which specializes in smart home and security solutions.
Kneron, founded in 2014 in San Diego, USA, opened a branch in Shenzhen in 2015. Its founder, Liu Juncheng, previously worked at Samsung and Qualcomm before venturing into AI chip development. His background and vision for neural network-based NPU processors highlight the growing global interest in AI hardware.
As the AI chip market continues to evolve, Alibaba’s strategic investments suggest a long-term commitment to shaping the future of intelligent technology. With a mix of domestic and international partners, the company is positioning itself as a key player in the next phase of the digital revolution.
A LED screen video processor is an essential component used to control, manage, and optimize the video signal for LED Display panels, ensuring high-quality image rendering, accurate color reproduction, and smooth video playback. It acts as an intermediary between the video source (e.g., computer, media player, camera, etc.) and the LED screen, handling tasks like signal conversion, scaling, synchronization, and color correction.
