|The application of tech can reduce power consumption in smartphones by 30%
|Chinese firm likely aiming to win order from Apple for iPads in the long run
|从长远来看，技术的应用可以将智能手机的功耗降低30%，
|中国公司可能的远期目标是赢得苹果iPad的订单。



Chinese display giant BOE was in talks with smartphone brand Honor to manufacture a two-stack tandem OLED panel to apply to a smartphone planned for later this year, TheElec has learned.
据TheElec了解，中国显示器巨头京东方正在与智能手机品牌荣耀 (Honor) 进行谈判，以制造一种双层串联OLED面板，以应用于计划于今年晚些时候推出的智能手机。

The pair believe that the use of the technology, where the OLED panel has two emission layers, can reduce the power consumption of the smartphone by approximately 30%, sources said. This means the smartphone can use a smaller battery that will allow the phone to be designed thinner, they added.
消息人士称，两人认为，使用OLED面板具有两个发射层的技术可以将智能手机的功耗降低约30%。他们补充说，这意味着智能手机可以使用更小的电池，这将使手机设计得更薄。

Honor also wanted the two-stack tandem OLED panel to have low-temperature polycrystalline oxide (LTPO) thin-film transistor (TFT) technology. But BOE had rejected the application of LTPO TFT, opting to have the panel use low-temperature polycrystalline silicon (LTPS) TFT that it already mass produces. The decision not to apply LTPO TFT is likely due to technology only contributing to around 5% to 10% reduction in power consumption, when two-stack tandem will be already be reducing 30% by BOE’s estimation. At the same time, applying the technology to the panel would require BOE to add more mask processes in production that will increase cost and potentially lead to lower yields.
Honor还希望双栈串联OLED面板具有低温多晶氧化物（LTPO）薄膜晶体管（TFT）技术。但京东方拒绝了LTPO TFT的应用，选择让面板使用已经批量生产的低温多晶硅（LTPS）TFT。不应用LTPO TFT的决定可能是由于技术仅有助于降低约5%至10%的功耗，而根据京东方的估计，双层串联技术已经使之降低了30%。同时，将该技术应用于面板将需要京东方在生产中添加更多的掩模工艺，这将增加成本并可能导致产量降低。

BOE is planning to use the third phase line at its B7 factory line in Chengdu, Sichuan Province, to manufacture the two-stack tandem OLED panel. B7 had been used to manufacture OLED panels for iPhones in the past, but this duty has shifted more to the B11 line, which means B7 is currently has operating at a lower rate than before. B7 has a capacity of 16,000 Gen 6 (1500x1850mm) substrates per month. As it is designed for single stack OLED panels, those with one emission layer, application of two-stack tandem OLED panels likely drop this capacity by half.
京东方计划使用其位于四川省成都市的B7工厂的第三阶段生产线来制造双层串联OLED面板。B7过去曾用于为iPhone制造OLED面板，但这一职责已更多地转移到B11工厂的生产线，这意味着B7目前的运行速度比以前低。B7 每月可生产 16000 台 Gen 6 （1500x1850mm） 基板。由于它是为那些具有一个发射层面板的单层OLED面板设计的，因此双层串联OLED面板的应用可能会使该容量降低一半。

BOE’s ultimate aim with its project with Honor is likely to secure experience to manufacture two-stack tandem OLED panels aimed at iPads. The company's South Korean rivals LG Display and Samsung Display are taking in projects to two-stack tandem OLED panels with Apple, but the Chinese display giant had not won such a project from Cupertino so far. It also remains to be seen whether BOE will succeed in commercially launching a two-tack tandem OLED panel aimed at smartphones with Honor. LG Display is the only display panel maker in the world that had succeeded in commercializing two-stack tandem OLED panels, which it manufactures and supplies for automotive applications.
京东方与荣耀合作的最终目标可能是确保制造针对iPad的双层串联OLED面板的经验。该公司的韩国竞争对手LG Display和Samsung Display正在与苹果公司合作开发双层串联OLED面板，但这家中国显示器巨头迄今尚未从苹果公司那里赢得这样的项目。京东方是否会成功地在商业上推出针对荣耀智能手机的双层串联OLED面板还有待观察。LG Display是世界上唯一一家成功将双层串联OLED面板商业化的显示面板制造商，该公司为汽车应用制造和供应。
