Full HD (FHD) panels have quickly become standard equipment for high-end smartphones, and currently account for about 30% of all smartphone shipments. Many panel manufacturers are also developing smartphone panels with higher absolute resolution (such as 4K) . It is predicted that the first commercial 4K smartphone panels will be developed and completed as soon as the end of 2014 and shipped in mid-2015.
It is observed that although 4K TVs are currently available everywhere, for mobile device panels such as smartphones and smart tablets, to achieve ultra-high resolution and absolute resolution, pixel density (PixelPerInch, PPI) brings to panel manufacturing More difficult.
Small and medium-sized panel analyst Yu Ningning pointed out that it is relatively easy to produce a 80ppi 55-inch 4K TV panel, but it is difficult to produce a 734ppi 6-inch 4K smartphone panel with high light transmittance and high electronic transmission characteristics and high yield Multiple; the difficulty includes many different processes, equipment and materials, of which the most difficult is the array (Array), color filter (ColorFilter) and module (Module).
The production of LCD and AMOLED panels face some of the same difficulties, but they are also different; in order to solve these problems, panel manufacturers are developing new technologies to be able to produce 4K smart phone panels at an economic cost.
For AMOLED displays, FMMRGB phosphor technology is extremely challenging; however, South Korea ’s Samsung has solved this problem, especially in the pixel design part, they use the larger PenTileRG + BG sub-pixel (Red-Green, Blue- Green) arrangement technology, in fact, the visual effect is similar to the real high resolution visually, and there is no big visual difference from the real RGB, so other AMOLED panel manufacturers have also followed this method. However, Samsung has absolute patent rights, and it is difficult for other panel manufacturers to mass produce high-resolution RGBAMOLED displays.
Although high-resolution exposure is a key problem, it is not enough to ensure the resolution of 4K mobile panel resolution; for AMOLEDPenTile, in addition to photolithography, other related materials and processes must also be matched to achieve high yields The ultra-high resolution panel has the advantages of low power consumption, high brightness, and low cost. It needs to optimize and successfully develop multiple device types, materials, and processes.
