At the "2017 Songshan Lake China IC Innovation Summit Forum" held recently, Dr. Zhang Ningsan, Vice President of Global GM and Global Sales, gave an important speech on the development trend of panel display driver ICs and how to deal with future market development challenges. In-depth analysis and outlook. In the selection event on behalf of China's advanced IC design level held in the same period of the forum, iML1998, which was the founder of the North, won the “Innovation IC†award.
Dr. Zhang Ningsan pointed out that high integration, low power consumption and high flexibility will be the necessary features of the next generation of display driver ICs. JiChuang North pioneered the world's first integrated programmable power management (PMIC) and Programmable gamma buffer (P-Gamma) single-chip TV display solution iML1998 represents the future of innovation.
iML1998 is suitable for large-size LCD display. It can support HD, FHD and UHD resolutions of 32 inches and above, and supports GOA display with narrow frame. In the future, it will be mass-produced in various sizes of LCD TV products of 28 inches or more. Currently, a single solution can be adapted to all LCD displays, and it is predicted that this product will become a key growth point in the traditional PMIC market.
For LCD TV display drivers, T-CON board power management is a very critical module, its performance is closely related to the display effect; in addition, T-CON board power management consists of multiple analog chips, its area and power consumption throughout A large percentage of the driver chips are required, so reducing the power and area of ​​the T-CON board power management is critical.
Taking a 55-inch 4K TV as an example, its T-CON board power management requires four analog chips, including PMU, P-Gamma buffer, VCOM, and PVCOM. Now, with just one iML 1998, they can be completely replaced.
Ø Rich color control through automatic P-Gamma technology;
Ø Through programmable P-Gamma adjustment technology, dynamic Gamma curve adjustment can be realized according to ambient light, which automatically adjusts the brightness of the panel to make the eyes feel more comfortable;
Ø High integration brings simplification of circuit design and saves PCB space;
Ø Lower power consumption, fewer pin counts, and lower cost;
Ø Higher reliability and higher performance;
The picture above shows the comparison before and after using P-Gamma technology.
Leading the show of IC innovation trendsIn the years of technological evolution, iML has formed unique technological advantages in the field of display ICs, especially in the highly integrated chip and highly flexible P-Gamma technology, leading in the related technology field, leading the integration of three generations of display ICs. trend. The first generation of products is represented by an independent multi-channel PMIC before 2014. iML integrates discrete DC-DC into a single chip; the second generation is an analog integrated chip from 2015 to 2017, with PMIC and Level Shifter or P-Gamma/VCOM has been integrated separately; the third generation is PMIC+P-Gamma/VCOM represented by the latest iML1998. At present, these three generations of products cover the low-end, mid-end and high-end markets, respectively, forming a comprehensive product layout.
Dr. Zhang Ningsan said that in the future, with the increase in the size and resolution of LCD TVs, the PMIC and P-Gamma integrated ICs that can automatically detect the regulated voltage and greatly improve the color and resolution performance will meet the requirements. The overall demand for large-size, high-resolution display driver chips. JiChuang North will always be committed to the development of innovative technologies, driving the upgrading and innovation of the industry!
