As the pandemic has eased, the global automotive market is picking up momentum, and it is estimated that the global shipments of automotive panels will exceed 200 million units in 2023. With the continuous demand for size enlargement and specification improvement in automotive panels, the adoption of TDDI architecture is becoming more prevalent, and it is expected that TDDI will gradually become the mainstream for automotive panels.

On the other hand, AMOLED panels have started to have opportunities for adoption in emerging electric vehicles and some high-end car models. However, their adoption has been slow due to potential issues with reliability, lifespan, and brightness. Currently, the overall penetration rate for AMOLED panels in the automotive sector is estimated to reach 6% by 2026.

Can Panel Manufacturers Replace Traditional Tier 1 Players and Directly Serve Automakers?

As traditional internal combustion engine vehicles transition to electric vehicles and the level of in-car electronics continues to rise, coupled with the development of autonomous driving technologies, the demand for automotive displays is constantly expanding. The integration of digital display panels with touch functionality is gradually becoming mainstream, and panel sizes are increasing, moving towards more integrated designs. Specifications such as resolution, wide viewing angles, and high refresh rates, as well as unique designs, are becoming focal points. Currently, display panel specifications are moving towards LTPS LCD panels, which offer larger sizes, superior display performance, and better energy efficiency.

Looking at the market conditions, after the outbreak of the pandemic in 2020, the demand for automotive panels declined, but it gradually recovered in 2021 and 2022. However, there is still an oversupply situation, and it is estimated that there will be a slight growth of 5.1% to reach 205 million units in 2023. In terms of shipment scale, China’s panel shipments maintain the best position with a share of over 40%, while Japanese panel manufacturers have been squeezed by Chinese counterparts, reducing their share to about 20%. Taiwan’s panel manufacturers account for approximately 21%, and Korean panel manufacturers represent 8%.

The traditional shipment model involves Tier 1 players contracting with car manufacturers for related validation, assembly, and supply chain management roles, and then subcontracting Tier 2 panel suppliers. With the transformation of the automotive industry and the semiconductor component shortages in the past few years, as well as the increased requirements for interior design in vehicles, car manufacturers are starting to seek better control over the supply chain. As a result, panel manufacturers may replace Tier 1 players and directly supply to automakers, and Tier 1 suppliers will face competition from panel manufacturers.

The Automotive TDDI Architecture Has Cost Advantages

In the early days, LCD automotive panels mainly used external touch solutions, with car-use DDI and independent touch ICs on the IC architecture. However, as panel sizes increased, the number of ICs used also increased, leading to higher costs. Therefore, the TDDI architecture became a new development direction.

TDDI is commonly used for panels up to 30 inches in size. A single TDDI solution can be used for 20-inch panels, while for 20-30 inch panels, a TDDI-cascade solution with approximately 2-3 TDDI-cascade architectures is often used. Panels larger than 30 inches use the LTDI (Local TDDI) structure.

New Display Technology Awaits Automotive Certification; Significant Growth Expected after 2025

AMOLED is mostly used in high-end car models or stylish new electric vehicles, but its rapid development is hindered by limitations in brightness, panel lifespan, and reliability. In comparison, LCDs with MiniLED BLU architecture offer similar display performance to AMOLED but at a more affordable price and with better safety, and they are expected to compete with AMOLED in the market.

In Q3, TV panel purchasing momentum is strong, with an estimated 7~8% growth by QoQ. Manufacturers are confident in raising prices due to increased demand, aiming to turn TV panel production profitable. As a result, TV panel prices are expected to continue rising, with increases of 2~8 USD for different sizes.

Monitor panel prices continue to rise in July, with consumer models showing higher demand than commercial ones. Brands focused on consumer models or smaller secondary brands are more likely to experience moderate price increases. Anticipated price adjustments for July: Open Cell products are up by around 0.2 ~0.5 USD, the 21.5-inch panel is up by 0.2 USD, the 23.8-inch panel is up by 0.2 USD, and 27-inch panel price remains unchanged.

In Q3, panel manufacturers consider raising prices for NB panels. Q2 saw a 30% shipment growth due to increased demand from brand customers, but Q3 demand is expected to be cautious, leading to a 3% shipment increase. Lower-end TN models have higher demand than IPS ones. Anticipated July prices: 14-inch and 15.6-inch TN models may see a slight 0.1 USD increase, while IPS models remain unchanged.

TrendForce reported that TV panel purchases are gaining momentum in the early July, with both Chinese and other major brand customers increasing their orders in preparation for the busy promotional season in the second half of the year. Overall, the purchasing momentum is expected to grow by 7-8% in the quarter. The demand-driven growth, coupled with balanced supply and demand, is likely to sustain the upward trend in TV panel prices. For July, prices are projected to rise by $2 for 32-inch panels, $3 for 43-inch panels, $6 for 50-inch and 55-inch panels, $7 for 65-inch panels, and $8 for 75-inch panels.

Meanwhile, MNT panel prices have experienced slight increases, but the market demand for commercial models remains weak compared to consumer models. Consequently, the price hikes are expected to be modest, and various panel manufacturers are implementing different pricing strategies for different customers and sizes. For July, MNT panel Open Cell prices are expected to rise by approximately $0.2 to $0.5, while 21.5-inch module prices will increase by $0.2 and 23.8-inch module prices by $0.1. Prices for 27-inch modules will remain stable.

As for NB panel prices, after a stable period, panel manufacturers are contemplating raising prices in the third quarter. However, brand customers remain cautious about the demand for the second half of the year, resulting in ongoing negotiations with panel manufacturers. The demand for lower-end TN models is stronger than for higher-end IPS models, leading brand customers to tend to accept slight increases in TN panel prices. For July, mainstream sizes like 14-inch and 15.6-inch TN models are expected to see a minor increase of $0.1, while prices for IPS models will remain stable.

Apple has finally launched the Vision Pro, an MR device equipped with Micro OLED, but the debut of the Apple Watch with Micro LED panels has been repeatedly delayed. According to a report from TechNews, industry insiders revealed that the production timeline for the Micro LED Apple Watch has been pushed back once again, from the second quarter of 2025 to the first quarter of 2026.

Over the past decade, Apple has invested at least $1 billion in developing Micro LED panels, aiming to reduce reliance on Samsung and strengthen control over critical component supplies. Once in mass production, Apple intends to execute the crucial “mass transfer” process on its own. This highlights Apple’s cautious approach in researching and developing Micro LED technology, which is still in the sample phase due to challenging production techniques and higher manufacturing costs.

In the Micro LED project, Apple has partnered with ams Osram for the development of Micro LED components, collaborated with LG Display for backplate production, and enlisted TSMC to manufacture 12-inch silicon wafers. Initially, Micro LED technology will be introduced in the Apple Watch Ultra model before gradually expanding to other product lines such as iPad and MacBook, with the ultimate plan of incorporating it into the iPhone.

Currently, the Apple Watch utilizes OLED technology, which has been in use since the launch of the first Apple Watch model in 2015. In comparison to OLED screens, Micro LED displays offer higher brightness and overcome issues such as screen aging and differential aging, making them a promising advancement.

With the release of Apple’s Vision Pro, its Micro OLED display technology has caught the attention of more people. In fact, global Micro OLED display manufacturers have been working in this field for many years. In recent years, Chinese manufacturers have been particularly active in this area. TrendForce has compiled the recent global manufacturers’ product and technological advancements in this article.
