Local time from May 12 to 17, the Society for Information Display (SID) hosted Display Week 2024 in the United States. According to Visionox (002387), the company unveiled a host of innovative technologies covering small, medium, large and full-size displays at the event, alongside cutting-edge application solutions for smart in-vehicle systems, smart home and smart office scenarios.
Relevant officials from Visionox stated that after the boom in pursuing differentiated form factors, the development of small-sized AMOLED displays has refocused on performance enhancement. At this exhibition, Visionox optimized and upgraded its products in terms of display performance, form design and integrated functions. It launched low-power-consumption solutions combining MLA (Micro Lens Array) plus COE (Color Filter On Encapsulation) as well as UBA (Ultra Brightness Array) plus COE.
The company also rolled out 4-sided ultra-narrow bezel 2K mobile display solutions and 3D spherical laminated wearable display solutions. Besides, it released integrated technologies including under-screen directional sound emission, dual-band dual-polarized AMOLED 5G millimeter-wave on-screen antenna, and integrated electromagnetic and capacitive touch solutions for AMOLED panels.
"Consumers increasingly prefer electronic products that are slim, high-performing and long-lasting in battery life," the official noted. To meet such market demands, Visionox’s newly launched combined MLA+COE and UBA+COE solutions deliver prominent advantages.
The integration of COE and MLA technologies cuts power consumption by 38%, while boosting brightness by over 38% under the same power input. When COE is paired with UBA technology, power consumption drops by 43% and brightness rises by 43%, perfectly catering to high-brightness outdoor display requirements.
In the popular foldable device sector, Visionox released an integrated solution for small foldable phones. Featuring an integrated design of a 5.9-inch inner main foldable screen and a 1.9-inch ring-shaped fixed curved secondary screen, it shortens module production procedures and reduces overall power consumption.
Currently, OLED displays are gradually expanding from small-sized devices such as smartphones and smartwatches to medium and large-sized products, boasting vast market potential. Targeting the low-power and high-image-quality demands for medium-sized displays, Visionox released a series of solutions including 20-640Hz wide-frequency LTPS technology, intelligent zoned multi-frequency technology, all-oxide AMOLED technology and curved floating display technology for medium-size panels. These forward-looking innovative technologies can well satisfy market needs. Meanwhile, it presented multiple medium-size innovative applications covering smart vehicle, smart home and smart office fields to empower diversified medium-size display scenarios.
Notably, Visionox unveiled its wide-frequency LTPS technology for medium-sized displays overseas for the first time. Featuring ultra-wide frequency range, low power consumption and strong comprehensive performance, it supports panel driving within an ultra-wide frequency range from 20Hz to over 640Hz, setting a new industry record. It also delivers flicker-free visual effects under low refresh rate, low grayscale and low brightness scenarios at 20Hz. Moreover, this technology requires no renovation or upgrading of existing AMOLED production lines and causes no loss in production capacity, making it a cost-effective low-power solution for medium-size displays.
To further reduce terminal power consumption, Visionox launched the world-leading intelligent zoned multi-frequency technology. It takes the lead in hardware-level upgrading, enabling arbitrary panel zoning with rows as the minimum unit, and allowing flexible adjustment of the quantity, position and size of horizontal zones. This realizes the brand-new function of multiple refresh rates on different areas of a single screen.
When applied to smartphones, this technology enables more precise matching between displayed content and refresh rates based on local display demands to further cut power use, and achieves more obvious power-saving effects on foldable phones, tablets, laptops and other medium-size devices.
In the large-sized display track, Visionox has pinned its bets on Micro-LED technology. Widely applicable to products of all sizes including large commercial displays, high-end TVs, in-vehicle screens, wearable devices and AR/VR equipment, Micro-LED is regarded by the company as a core strategic track for future display layout.
At the exhibition, Chenxian Optoelectronics, in which Visionox holds shares, showcased the world’s leading 88-inch P0.5 front-maintenance TFT-based Micro-LED splicing display, applicable to commercial display, command and dispatch, high-end conferences and other scenarios. Equipped with 25-micron LED chips, it adopts industry-original technologies to greatly improve color and brightness uniformity, presenting clear and vivid images under various lighting conditions.
This splicing screen supports front-side maintenance, allowing direct replacement and maintenance from the front to lower maintenance costs and time costs. It also supports unlimited splicing to fully meet customized customer demands.
In September 2023, Chenxian Optoelectronics broke ground on the world’s first TFT-based Micro-LED production line, accelerating the transition from pilot research and development to commercialization. In consideration of the industrialization maturity of Micro-LED technology and future market prospects, the production line is initially positioned for large-sized commercial displays, scheduled to achieve mass shipment by the end of 2024 with an annual panel capacity of 18,000 square meters after full operation.
In terms of full-size display applications, Visionox also exhibited mass-production progress of its G6 production line based on ViP (Vision Intelligent Pixel) technology.
Visionox’s ViP technology breaks multiple bottlenecks of traditional FMM-based AMOLED manufacturing in performance, cost and size, greatly improving AMOLED panels in service life, brightness and image quality, and accelerating the penetration of AMOLED displays across full-size markets.
Visionox officially debuted ViP technology globally in May 2023, and lit up the first batch of ViP-based AMOLED modules in December the same year, marking a crucial step towards large-scale mass production.
