Mini LED backlight displays provide an opportunity for panel makers such as AU Optronics Corp (AUO, 友達光電) to seize a bigger share of the advanced displays market, given the emerging technology’s significant advantages in brightness, reliability and performance over OLED technology, TrendForce Corp (集邦科技) said in a report on Monday.
Mini LED backlight displays rival OLED panels in their ability to contrast colors, the Taipei-based researcher said.
Aside from those merits, mini LED backlight displays are also more competitive in terms of manufacturing cost and power consumption, so they should deliver a higher cost-to-performance ratio than rival technologies, TrendForce said.
Mini LED backlights are forecast to be used in 20 percent of computer monitors, 15 percent of TV panels and 10 percent of tablet and laptop panels by 2024, the researcher said.
Taiwanese panel makers AUO and Innolux Corp (群創光電) have been conservative on the production of large-sized OLEDs for TVs and PCs, due to the manufacturing costs.
AUO only ships OLED panels for wearable devices from its 3.5G plant.
The two companies have been investing in mini LED technology, which is considered a good bet to compete with the OLED technology lauded by their South Korean rivals.
Innolux believes its 120-inch mini LED TV panels could outsell OLED TV panels due to the size and cost advantages, helping it win the race for dominance of the sector, Innolux president James Yang (楊柱祥) told reporters last month.
To make quick inroads, AUO and Innolux have been working with their LED subsidiaries to develop mini LED backlight modules, TrendForce said.
AUO has been working with Lextar Electronics Corp (隆達電子), while Innolux has teamed up with Advanced Optoelectronic Technology Inc (榮創科技) and Epileds Technologies Inc (光鋐科技) to develop panels for premium TVs, gaming monitors and vehicle displays, the researcher said.
Chinese firms China Star Optoelectronics Technology Co (華星光電) and BOE Group Co (京東方) have also invested in mini LED backlight displays by leveraging their edge in LCD manufacturing, TrendForce said.
Taiwanese LED chip manufacturer Epistar Corp (晶電) is working with its subsidiary Yenrich Technology Corp (元豐新科技) to produce mini LED light source modules to extend its reach into the backlight module market, the researcher said.
CHIP RACE: Three years of overbroad export controls drove foreign competitors to pursue their own AI chips, and ‘cost US taxpayers billions of dollars,’ Nvidia said China has figured out the US strategy for allowing it to buy Nvidia Corp’s H200s and is rejecting the artificial intelligence (AI) chip in favor of domestically developed semiconductors, White House AI adviser David Sacks said, citing news reports. US President Donald Trump on Monday said that he would allow shipments of Nvidia’s H200 chips to China, part of an administration effort backed by Sacks to challenge Chinese tech champions such as Huawei Technologies Co (華為) by bringing US competition to their home market. On Friday, Sacks signaled that he was uncertain about whether that approach would work. “They’re rejecting our chips,” Sacks
Taiwan’s long-term economic competitiveness will hinge not only on national champions like Taiwan Semiconductor Manufacturing Co. (TSMC, 台積電) but also on the widespread adoption of artificial intelligence (AI) and other emerging technologies, a US-based scholar has said. At a lecture in Taipei on Tuesday, Jeffrey Ding, assistant professor of political science at the George Washington University and author of "Technology and the Rise of Great Powers," argued that historical experience shows that general-purpose technologies (GPTs) — such as electricity, computers and now AI — shape long-term economic advantages through their diffusion across the broader economy. "What really matters is not who pioneers
TAIWAN VALUE CHAIN: Foxtron is to fully own Luxgen following the transaction and it plans to launch a new electric model, the Foxtron Bria, in Taiwan next year Yulon Motor Co (裕隆汽車) yesterday said that its board of directors approved the disposal of its electric vehicle (EV) unit, Luxgen Motor Co (納智捷汽車), to Foxtron Vehicle Technologies Co (鴻華先進) for NT$787.6 million (US$24.98 million). Foxtron, a half-half joint venture between Yulon affiliate Hua-Chuang Automobile Information Technical Center Co (華創車電) and Hon Hai Precision Industry Co (鴻海精密), expects to wrap up the deal in the first quarter of next year. Foxtron would fully own Luxgen following the transaction, including five car distributing companies, outlets and all employees. The deal is subject to the approval of the Fair Trade Commission, Foxtron said. “Foxtron will be
BUBBLE? Only a handful of companies are seeing rapid revenue growth and higher valuations, and it is not enough to call the AI trend a transformation, an analyst said Artificial intelligence (AI) is entering a more challenging phase next year as companies move beyond experimentation and begin demanding clear financial returns from a technology that has delivered big gains to only a small group of early adopters, PricewaterhouseCoopers (PwC) Taiwan said yesterday. Most organizations have been able to justify AI investments through cost recovery or modest efficiency gains, but few have achieved meaningful revenue growth or long-term competitive advantage, the consultancy said in its 2026 AI Business Predictions report. This growing performance gap is forcing executives to reconsider how AI is deployed across their organizations, it said. “Many companies
