LG ha annunciato quest’oggi un nuovo pannello Quad HD (2560*1440 pixel) AH-IPS LCD (LTPS) da 5.5 pollici, con densità di pixel pari a 538 PPI.
Il display ha recentemente superato i test di verifica da parte dell’organizzazione norvegese NEMKO e verrà adottato sui prossimi device top di gamma della casa coreana entro la prima metà del 2014 (qualcuno ha detto G3?):
The certification comes shortly before the new Quad HD LCD panel will be unveiled with the forthcoming LG’s flagship smartphone to be launched in the first half of the year.
I punti forti del prodotto sono l’estrema sottigliezza (1.2 millimetri) e il ridotto spessore dei bordi (1.15 millimetri). Oltre a ciò, il pannello presentato da LG sembra in grado di offrire una luminosità pari a quella dei pannelli Full HD nonostante l’elevatissima quantità di pixel.
La qualità dei colori è già stata certificata grazie al rispetto dello standard “100 percent RGB color reproduction”, così come l’ottimo livello di contrasto.
LG non ha confermato ufficialmente la presenza di un display QHD sul top di gamma LG G3, tuttavia lo smartphone (che sarà presentato il prossimo 27 Maggio) sembrerebbe il candidato ideale per l’utilizzo del pannello presentato quest’oggi.
Allego di seguito il comunicato stampa ufficiale:
Seoul, Korea (May 8, 2014) – LG Display announced today that its 5.5-inch Quad HD (QHD) AH-IPS LCD panel for smartphones was certified as a QHD display after passing verified tests by NEMKO, the Norway-based international testing and certification organization for electrical products. The certification comes shortly before the new Quad HD LCD panel will be unveiled with the forthcoming LG’s flagship smartphone to be launched in the first half of the year.
The certified 5.5-inch QHD AH-IPS LCD panel has 2560 x 1440 pixels, four times the image resolution of HD panels and 1.8 times higher resolution than a Full HD panel. With 538 pixels per inch, this panel also meets the 100 percent RGB color reproduction standard.
This panel, which will go into mass production shortly, will offer superior performance to other existing smartphone panels. This is an ultra-slim panel with a mere 1.2 mm thickness and has a 1.15 mm bezel, which will be the narrowest available and 0.05 mm less than panels introduced last year.
In addition, the panel has achieved the same level of brightness as a Full HD panel. It is difficult to raise penetration ratio in higher resolution panels since they have more pixels. However, LG Display successfully achieved higher brightness by improving the penetration ratio through enhancing the pixel structure design and aperture ratio in the LTPS backplane.
The Quad HD display produces images in sharper color and contrast than regular displays because of the greater amount of pixels. This means that high resolution images and videos in the Blu-ray format can be viewed in a fully vivid and realistic manner. The display retains the readability of letters and images without distorting them when they are enlarged while surfing the internet or working on documents.
“This product fulfills the core qualities of smartphone displays, which are high resolution and slim design, and I believe the consumers can enjoy vivid images that are close to real life with this display,” said Byung-koo Kim, Vice President and Head of LG Display’s IT/Mobile Development Group. “LG Display will continue to maintain technology leadership in the super high-resolution smartphone display market above 500 ppi resolution, which will take off this year.”
According to DisplaySearch, the shipment of premium smartphone displays based on LTPS backplanes is expected to grow to 780 million units by this year and 940 million units by next year. These products are going to maintain sufficient competitive advantage in premium product categories where large size, high resolution and low power consumption are key factors.
