Display driver IC: Growing Demand but Lingering Concerns

---

---

The latest study by TrendForce shows that demand for large-size and mobile driver ICs will steadily grow as various applications recover. However, the speed of capacity supply adjustment and competition among different technologies will remain the key focus in the next few quarters.

Another thing worth noting is that the US chip ban has led to a trend of independent development between Chinese and non-Chinese supply chains. While this may increase production time and cost, it also presents opportunities for individual Chinese domestic suppliers and Taiwanese wafer foundries to acquire fresh orders.

Observations by TrendForce on each sector of driver ICs are summarized below-

• Large-size panel driver ICs: demand is expected to recover gradually and stabilize prices, but suppliers are cautious about inventory, which could lead to a supply shortage if demand surges too quickly.
• TDDI for mobile devices: prices and inventory have reached a low point, with a small rebound expected. In the long run, AMOLED panels are expected to dominate, so IC suppliers will need to explore new applications for medium-sized panels.
• AMOLED driver ICs: UMC’s 28nm high-voltage process is producing AMOLED driver ICs. If Apple shifts all 40nm AMOLED driver IC production to 28nm, TSMC’s 28nm capacity availability will be crucial to the market’s supply-demand balance.
• RAM-Less AMOLED driver ICs: RAM-Less AMOLED driver ICs with Chinese flexible AMOLED panels are gradually taking shape due to China’s domestic policy. However, the rapid price drop of Full-Ram AMOLED has caused brands to hesitate on adopting Ram-Less AMOLED.
