摘要
用于AM-OLED的LTPS TFTs的阈值电压（Vth）和沟道迁移率（μ）在空间分布上是不够均匀的，用于AM-OLED的a-Si TFTs的Vth和μ会随时间偏移，这些缺点会造成显示屏亮度的不均匀性和不稳定性。为此，需要引入各种像素补偿电路，使显示屏发光亮度的均匀性和稳定性符合商品要求（文章分为两期刊登，本篇为第一部分）。
Abstract
The uniformity of the threshold (Vth) and electron mobility (μ) of LTPS TFTs used in AM-OLED is not good enough. The Vth and μof a-Si TFTs used in AM-OLED shift time to time. This causes the non-uniformity and non-stability of the brightness in panel. To solve this issue, it is necessary to introduce different pixel compensation circuit, then making the uniformity and stability of the brightness in panel to meet commercial demands.
