Difference between TFT and LCD
Recently, I read about a German
article, which explains the difference between TFT (Thin Film
Transistor) and LCD (Liquid Crystal Displays) and I found it
interesting. This led me to write a short article about this topic for
my users too.
For digital photo frames, TFT and LCD are often used synonymously, but
in fact, there is a difference between these two panels. Generally
speaking, TFT is one kind of LCD. Older LCD monitors (passive matrix
structure) do not use an active matrix structure, like new LCD/TFT
monitors use. Active-matrix addressed displays look brighter and sharper
than passive-matrix addressed displays of the same size, and generally
have quicker response times, producing much better images. Therefore, it
can be concluded that TFT LCD are better than "normal" LCD displays and
it is recommended to buy digital photo frames with TFT LCD.

A thin film transistor liquid crystal display (TFT-LCD) is a variant
of liquid crystal display (LCD) which uses thin film transistor (TFT)
technology to improve image quality. TFT LCD is one type of active
matrix LCD, though it is usually synonymous with LCD. High-resolution
color displays such as modern LCD computer monitors and televisions use
an active matrix structure. A matrix of thin-film transistors (TFTs) is
added to the polarizing and color filters. Each pixel has its own
dedicated transistor, allowing each column line to access one pixel.
When a row line is activated, all of the column lines are connected to a
row of pixels and the correct voltage is driven onto all of the column
lines. The row line is then deactivated and the next row line is
activated. All of the row lines are activated in sequence during a
