Technical support behind the Tiananmen Parade: 1.3 million domestically produced chips safeguard ultra clear displays

At the just concluded September 3rd military parade, the huge LED screen in Tiananmen Square perfectly presented every shocking moment of the parade with 8K ultra high definition resolution and HDR Vivid dynamic range technology. Behind this is the precise control of about 1.3 million domestically produced display driver chips - they are based on the independently developed ICND2055S and ICND2018AP by Jichuang North, achieving a leapfrog breakthrough from technological catch-up to independent leadership, marking the true independent controllability of China's ultra high definition display industry in the key component field.

As the "nerve center" of visual presentation, the ICND2055S and ICND2018AP core chips provided by Jichuang North play a crucial role. ICND2055S is a PWM constant current output driver chip designed specifically for full-color LED displays. It has 16 PWM constant current outputs, supports any scan from 1-32, and has a refresh rate of up to 7680Hz. The LED display row driver chip ICND2018AP has 8 channels, a maximum output current of 2.5mA, and advanced functions such as LED bead protection. The two chips work together to make the high-definition large screen image of the ceremony more smooth. Even under the capture of high-speed cameras, the parade image remains extremely smooth, completely eliminating flicker.

In addition, the live broadcast of the military parade adopts the 8K ultra high definition production standard and strictly follows the high standard requirements of HDR Vivid, posing extremely high challenges to the display driver chip. As a dynamic HDR standard independently innovated by China, HDR Vivid can more accurately restore the brightness, color, and contrast of each pixel, which puts extremely high demands on the processing accuracy and response speed of display driver chips. The domestic chip has passed the test of this grand ceremony, proving its ability to support the highest specifications of audiovisual content.

In fact, the breakthrough of display driver chips is just a microcosm of the development of China's new display industry. In recent years, with the rise of companies such as Jichuang North, Ming Microelectronics, and Fuman Microelectronics, the localization rate in the field of display driver chips has continued to increase. At present, domestic chips have taken a dominant position in the mid to low end market; In the high-end market, the substitution process is accelerating. At present, China has gradually formed a complete industrial chain layout including chip design, wafer manufacturing, packaging and testing, panel manufacturing, and whole machine assembly.

With this military parade as a landmark event, the large-size LED display market is ushering in a new round of growth opportunities. From the snowflake shaped main torch stage of the Winter Olympics, to the immersive stage of the Spring Festival Gala, and to the huge advertising screens of urban landmarks, domestic display driver chips are supporting a billion dollar application market. Especially in commercial fields such as command and control centers, conference education, and high-end retail, the demand for high specification display products is rapidly increasing.

From the National Day parade to the Winter Olympics, from the Spring Festival Gala stage to urban lighting, domestically produced display driver chips are taking on visual responsibilities in various national level major occasions. On Tiananmen Square, the faint light controlled by each chip converged into a brilliant picture - not only a technological victory, but also a vivid portrayal of an industry's transition from dependence on imports to comprehensive independence.
