Panel Twins Pivot to Semiconductor Packaging, Seeking New Growth Path

In recent years, Taiwan's panel and touch panel industries have faced multiple challenges, including the saturation of traditional consumer electronics demand and fierce global competition in LCD panel production, prompting the "twin panels" and related supply chains to actively seek transformation pathways. AU Optronics and major touch panel manufacturer TPK simultaneously released their latest revenue figures today. AU Optronics' consolidated revenue for September remained steady compared to August, while TPK's September performance was also on par with the previous month. Despite the lack of significant fluctuations in single-month revenue figures, at this critical juncture when the core panel business is facing a transitional period, the capital market and industry analysts have long looked beyond monthly revenue figures, turning their high focus on the diversified transformation achievements actively promoted by the two companies in recent years, especially the latest progress and market deployment in crossing over into the field of advanced semiconductor packaging.

Reviewing the transformation trajectories of Taiwan's two major panel makers, Innolux had previously achieved substantial breakthroughs in the field of advanced semiconductor packaging, gaining technological recognition from international giants and taking the lead in achieving stable shipments, injecting a shot in the arm for the transformation of the entire panel industry. Amidst this wave of panel manufacturers shifting toward semiconductor packaging, AU Optronics has not lagged behind. Recently, at the annual Semiconductor Taiwan exhibition, the company showcased its strength by publicly displaying glass core substrate technology dedicated to advanced packaging for the first time, announcing to the outside world that its technological prowess has successfully extended from the display field to the lithography and substrate manufacturing processes of semiconductor packaging. By combining the mature technologies of panel-level processes with the demands of semiconductor packaging, AU Optronics attempts to secure a foothold in the global supply chain of heterogeneous integration and advanced packaging, competing for high-value-added orders.

In addition to traditional panel giants actively seeking cross-domain breakthroughs, touch panel manufacturer TPK also officially announced its entry into the advanced semiconductor packaging business recently. TPK has long cultivated touch and display module integration in the past, but has similarly faced pressures of compressed gross margins and market competition in recent years. To seek a second growth curve for its operations, the company decided to transform its profound technical foundation accumulated in the fields of precision touch and large-size glass processing into a stepping stone to enter the semiconductor packaging market. With the joining of TPK, the lineup of Taiwan's panel and touch supply chains entering advanced semiconductor packaging is growing stronger day by day, forming a new force of "panel-level packaging" that cannot be underestimated, and also raising high expectations from the outside world as to whether these traditional optoelectronics manufacturers can successfully make a glamorous transformation.

From the macro perspective of industrial technology development, traditional semiconductor packaging mostly relies on silicon wafers as carriers. However, with the rapid development of artificial intelligence, high-performance computing, and big data applications, chip sizes continue to expand, and the requirements for packaging substrates regarding heat dissipation, signal transmission speed, and flatness have reached unprecedented heights. Against this background, the large-size glass substrates and panel-level fan-out packaging processes possessed by panel manufacturers happen to provide excellent alternative solutions. Glass substrates possess excellent electrical characteristics and thermal stability, which can effectively reduce signal attenuation and accommodate more transistors. This is precisely the core advantage that optoelectronic giants such as AU Optronics and TPK dare to rely on to cross over and challenge advanced semiconductor packaging, transforming panel manufacturers from past display component suppliers into important promoters of advanced semiconductor processes.

Looking at the flat September revenue performance of AU Optronics and TPK as a whole, it indicates that the terminal demand for the traditional panel and touch core businesses currently presents a mild and stable pattern, without dramatic seasonal explosions or recessions. However, for investors and industry observers, the stability of revenue figures merely represents the consolidation of the baseline at the current stage; the real key lies in when the revenue contribution proportion of the two companies in non-display businesses, especially in the field of advanced semiconductor packaging, will become visible in the coming quarters. As panel makers' glass core substrate technology gradually moves from exhibition floors to actual mass production verification, Taiwan's optoelectronics industry is at a historical intersection moving from traditional displays to the high-tech semiconductor supply chain. Its subsequent customer introduction progress and transformation effectiveness will become the most critical indicators determining long-term corporate competitiveness.
