The reviews talk endlessly about everything the latest i-Plonk lacks: the screen isn't OLED, it doesn't display e-ink, it's heavy, the battery life isn't so great, there's no stylus, and so on.
回顾无止尽地谈论最新的i-Plonk（讽刺）缺少的：屏幕不是OLED、不是电子墨水、太重、电池续航能力不强、没有触摸笔，等等。
The I-V curve shows rectification characteristics, which makes clear that the current of the OLED is injection-limited when the injection barrier is high.
模拟的I-V曲线呈整流特性，说明在注入势垒较大的情况下，器件的电流是注入受限的。
