Samsung Display and LG Display announced on the 13th that they will participate in 'Display Week 2025,' hosted by the Society for Information Display (SID), the world's largest display event.
The SID 2025, held from the 13th to the 15th (local time) at the McEnery Convention Center in San Jose, California, will be attended by display corporations and experts from around the world to share cutting-edge technology and R&D results.
Samsung Display will showcase the 'EL-Quantum Dot (QD)' this year, which has improved performance compared to the previous year. EL-QD is a product that integrates next-generation electroluminescent technology and was first unveiled by Samsung Display last year under the name 'QD-LED' at 'SID 2024.'
Currently, the commercialized QD-OLED creates colors through photoluminescence (PL) by passing light from OLED through the QD light-emitting layer, while the EL-QD uses an electroluminescent method that directly illuminates R·G·B pixels made of QD without OLED. It maximizes the unique advantage of QD, excellent 'color accuracy,' while also reducing power consumption.
The EL-QD that Samsung Display is introducing this time comes in two versions: a 400-nit high-brightness product and a 264 PPI high-resolution product. The high-brightness product is over 50% brighter than the product (250 nits) introduced last year. It boasts the highest brightness among all products revealed to date and has improved the lifespan of blue materials, which is considered the biggest challenge for the commercialization of EL-QD.
LG Display divided its exhibition space into three zones to showcase the evolution of large OLED technology, vehicle display solutions aimed at future mobility, and next-generation display technologies.
In the large OLED zone, the theme was 'another evolution for mass adoption,' showcasing the excellence of the fourth-generation OLED panels and the TVs and gaming panels that incorporate them.
LG Display's fourth-generation OLED panels applied its unique technology called 'Primary RGB Tandem' that independently stacks RGB (red, green, blue) elements to emit light. This has achieved a maximum brightness (luminance) of 4000 nits, which is the highest level in the industry (where 1 nit is equivalent to the brightness of a single candle).
It has developed and applied special films to express natural colors and brightness in any environment, allowing for vivid colors and blacks even in bright indoor spaces as if watching in a dark theater.
LG Display plans to accelerate its strategy targeting the premium market with its fourth-generation OLED panels, including AI TVs and gaming OLEDs.
