Recently, ICNA3512, a new OLED mobile phone chip launched by Chipone, has passed the verification of domestic first-line terminal customers and started mass production, which is used in its latest OLED curved screen mobile phone products. This chip is the first OLED mobile phone display driver chip launched by domestic IC design manufacturers to support LTPO dynamic refresh rate technology, folding screen and under-screen camera.  

ICNA3512 realizes localization from design, OEM production to chip packaging and testing, which breaks the monopoly situation of foreign manufacturers and is of great significance in terms of supply chain security.  

1. ICNA3512 has passed the verification of domestic first-line terminal customers

① ICNA3512 is a FHD+ high refresh rate OLED mobile phone module display driver chip, which integrates advanced display technologies such as folding cascading solutions, self-designed visual effect optimization algorithms, and timing requirements for LTPO power saving technology.    

It is the first time to adopt a national production supply chain, which not only fills the gap in the relevant domestic fields, but also helps customers realize the diversification of the supply chain, effectively ensuring the security of the supply chain.   

Adopting new technology for the first time, the team faced many new challenges in the process of introducing the domestic supply chain. The Chichuang North team faced up to the difficulties in the process of improving process yield and solving testing problems. In order to ensure the normal progress of the project, the R&D team and the supply chain team continue to improve the design and development environment and process in the tight development schedule, effectively form a joint force, and jointly resist risks and challenges.  

② Breakthrough in mass production of display driver chips from 0 to 1 in the national supply chain  

The product achieves a round of test pass during the terminal verification process. The application, R&D and algorithm teams went deep into the front line of modules and end customers, and actively cooperated and responded to various requirements of customers to complete the verification. The professionalism of the team has won the recognition of modules and end customers.  

ICNA3512 has passed the verification of domestic first-line terminal customers, realizing the mass production breakthrough of Chipone’s national supply chain mobile phone OLED display driver chip from 0 to 1 at the client end, and providing Chipone’s continuous market development for other domestic mainstream terminal customers. strong support.  

2. As a supplier of total OLED display solutions

Chipone's ability to become a member of the first echelon of domestic OLED chip manufacturers is mainly due to the company's forward-looking layout in related fields of OLED display technology. Chipone is also one of the few domestic suppliers that can provide overall OLED display solutions.  

In addition to the continuous research and development of display driver chips for OLED mobile phones, Chipone also has a complete product line and mature products in display related fields such as OLED wearables, touch control, power management, and side fingerprint control, which can focus on customer needs and provide Customized OLED display overall solution.  

① OLED terminal application product layout  

The wearable OLED display driver chip ICNA3311 launched in 2021, the self-designed clock control function of the IC can achieve a minimum refresh rate of 1Hz. It has been mass-produced in all major wearable terminal companies.   

In response to the touch control needs of different terminals, Chipone has introduced the ICNT9268OLED mobile phone touch chip to the market. This chip has many advantages such as multiple channels, flexible selection, and high reporting rate. HPP/USI Active Pen Protocol. It has been verified and passed in the first-tier panel factories by the end of 2022. The ICNT9288 is the latest touch product launched this year, which can support 8-inch to 10-inch folding screens, and simultaneously supports tablet and notebook applications. It has the advantages of multiple channels, small package, good mechanism matching, flexible channel selection, and high reporting rate. features, and supports the HPP/USI active pen protocol. This chip will be used in the new flagship folding mobile phones to be released by first-line terminal brands in 2023.   

② Being at the forefront of technological innovation, Chipone is advancing towards the research of a new generation of display technology This year, Chipone will also launch ramless series products and 28nm technology display chip flagship products. It can support up to 1.5K resolution and support the latest LTPO2.0 technology. Compared with the past, the new products will reduce power consumption to a greater extent and fully meet the new needs of the high-end market. At present, Chipone has invested in the research and development of new optical fingerprint technology under the screen to support Pol-less screen, the next-generation display technology of OLED. The transmittance of Pol-less screen is low, and the traditional optical lens fingerprint under the screen cannot be adapted. Chipone combines its own advantages in the display field, and is at the forefront of the market in the field of adapting Pol-less screen fingerprints, providing customers with a variety of overall OLED display solutions. Chipone also has a complete product layout in the fields of power management and side fingerprints. The products launched have been applied in many front-line terminals and have been recognized and supported by customers.  

With the rapid development of terminal application technology, technologies in the fields of mobile phones, wearable devices, AR/VR, human-computer interaction, and metaverse are changing with each passing day. The demand of the terminal market will continue to drive OLED chip innovation.
