液晶常用的场效应管

液晶常用的场效应管
英文回答：
Thin-film transistors (TFTs) are a type of field-effect transistor (FET) that is commonly used in liquid crystal displays (LCDs). TFTs are used to control the flow of current through each pixel in an LCD, which in turn
controls the brightness and color of that pixel.
There are two main types of TFTs used in LCDs: amorphous silicon (a-Si) TFTs and polycrystalline silicon (p-Si) TFTs. A-Si TFTs are made from a thin film of amorphous silicon, which is a non-crystalline form of silicon. P-Si TFTs are made from a thin film of polycrystalline silicon, which is a crystalline form of silicon.
A-Si TFTs are less expensive to manufacture than p-Si TFTs, but they also have lower performance. P-Si TFTs have higher performance than a-Si TFTs, but they are also more
expensive to manufacture.
The choice of which type of TFT to use in an LCD depends on the desired performance and cost constraints.
For low-cost applications, a-Si TFTs are typically used.
For high-performance applications, p-Si TFTs are typically used.
In addition to a-Si TFTs and p-Si TFTs, there are also
a number of other types of TFTs that can be used in LCDs. These include cadmium selenide (CdSe) TFTs, zinc oxide (ZnO) TFTs, and indium gallium zinc oxide (IGZO) TFTs. Each type
of TFT has its own unique advantages and disadvantages, and the choice of which type to use depends on the specific application.

在液晶显示器（LCD）中，薄膜晶体管（TFT）是一种常用的场
效应晶体管（FET）。

TFT 用于控制流经 LCD 中每个像素的电流，
进而控制该像素的亮度和颜色。

在 LCD 中使用的 TFT 主要有两种类型，非晶硅 (a-Si) TFT
和多晶硅 (p-Si) TFT。

无定形硅 TFT 由无定形硅薄膜制成，无定
形硅是一种非晶态硅。

多晶硅 TFT 由多晶硅薄膜制成，多晶硅是一
种晶态硅。

与 p-Si TFT 相比，a-Si TFT 的制造成本更低，但性能也更低。

p-Si TFT 比 a-Si TFT 具有更高的性能，但制造成本也更高。

在 LCD 中使用哪种类型的 TFT 取决于所需的性能和成本限制。

对于低成本应用，通常使用 a-Si TFT。

对于高性能应用，通常使用
p-Si TFT。

除了 a-Si TFT 和 p-Si TFT 外，还有许多其他类型的 TFT 可
用于 LCD 中。

这些包括硒化镉 (CdSe) TFT、氧化锌 (ZnO) TFT 和
铟镓锌氧化物 (IGZO) TFT。

每种类型的 TFT 都具有其独特的优点
和缺点，选择哪种类型取决于具体应用。
