China's first All-in-one LCD driver chip set to launch HD720/HD800 small and medium size driver chip


ChipOne Technology (Beijing) Co., Ltd. (hereinafter referred to as JiChuang) introduced the All-in-one small-size LCD driver chip ICN9706. The chip supports both the HD720 and flat-panel HD800 resolutions and supports up to 8-inch screens. The ICN9706 is the first LCD driver chip in China that combines drive and TCON to support both mobile phones and tablets.


According to the forecast data released by IDC, the shipment of smart phones in the domestic market will still exceed 460 million by 2017, and the market size is about 740 billion yuan. After the 4G era, consumers are expecting more and more high-performance, high-definition, ultra-thin, low-power consumption, etc. The screen resolution of mobile phones is also from the earliest QVGA and VGA. , evolved to 720P (HD); HD720 resolution has been the most mainstream configuration in the market.

All-in-one architecture, flexible application for mobile phones and tablets

Unlike the large-size panel driver chip, the ICN9706 driver chip uses an all-in-one architecture to integrate the Source driver, Gate driver, and TCON into a single chip, saving board space while reducing power consumption. At the beginning of the design, ICN9706 takes into account the current trend of smartphones and tablets. It can flexibly support smartphones and flat-panel HD720/HD800 applications without the need to build separate system platforms for mobile phones and tablets, making design easier and more flexible. , shortened the time for the launch of new products.

Low power consumption

It is well known that the power consumption requirements of mobile terminal devices are very strict, and the ICN9706 has made great efforts in low power consumption. In the mobile phone RGB patten application scenario, the power consumption is only 90 milliwatts, and the full load peak is only 140 milliwatts.

Project power consumption

RGB patten full load power

Mobile phone power consumption 90mW140mW

Tablet power consumption 180mW250mW

Full support for all glass in the market

Because the ICN9706 needs to support both mobile phones and tablet products, it is designed to take into account different screen applications, maximizing product compatibility, enabling the ICN9706 to support all of the glass currently on the market for the convenience of module manufacturers.

Gu Wenjun, chief analyst of Xinmou Research, said that “the display industry in mainland China has a huge market of 10 billion scale. The LCD panel industry has made great progress in the past two years and has the ability to control and control the entire industry chain.

Mainland Chinese companies have huge opportunities in this field, and they have a strategic layout and overtaking in corners."

Zhang Heng, Senior Vice President of JiChuang North, introduced: "This small-size driver chip is made by the industry's international professional development team. It adopts the mature Wafer process technology, strict cost control design concept, and strict product verification. Competitive products. This chip will be mass-produced in September." Zhang Heng said: "Mobile Internet + has driven the development of China's intelligent mobile terminal industry. Ji Chuang has been positioning the company's products around the application of flat display technology. In the future, the company will make product extensions based on the integration of TV, computer and mobile phone multi-screen. Then, the company will launch FHD, 2K and other small size drive products.
