The ambitious United Nations Sustainable Development Goals (SDGs), from reducing food waste to enhancing global healthcare access, hinge on a connected world where every object whispers valuable data. As technology strives to address environmental challenges, healthcare needs, and promote responsible consumption, traditional… Read More
Many TFT technologies in the market today are based on 4-terminal devices. In contrast, the SPICE simulators from other vendors can only support 3-terminal TFT compact models. Although one can model a 4-terminal TFT device using a 3-terminal TFT compact model, this scenario is far from ideal, can create a burden to the modeling
I’ve used OLED (Organic Light-Emitting Diode) displays for many years in my monitors, laptops, tablets, e-readers and smart phones; and knew that the AMOLED (Active-Matrix OLED) displays used thin-film transistor technology where each pixel can be controlled, but I hadn’t considered the actual design process… Read More
As I write there are multiple displays in front of me that use TFT, LCD or OLED displays:
I knew that the acronym for TFT meant Thin Film Transistors, but I hadn’t heard that FPD stands for Flat Panel Detectors. It turns out the FPD are solid-state sensors used in x-ray applications, similar in operation to image sensors for digital photography and video. I’ll be attending and blogging about what I learn… Read More
Two weeks ago I blogged about amorphous silicon and how that material is well-suited for designing TFTs. Today I’m following up after watching the archived webinarpresented by Nam-Kyun Tak of Silvaco. After clicking on that link you’ll be brought to a brief sign-up page and then can watch the archived webinar in your… Read More
Most ICs are fabricated with crystalline silicon (c-Si), which is a tetrahedral structure forming a well-ordered crystal lattice. There’s another form of semiconductor material called amorphous silicon (a-Si) which has no long-range periodic order. It turns out that a-Si is a great material for the active layer in thin-film… Read More
Traditionally logic devices built on top of thin-film-transistors (TFTs) have used one type of device, either an NMOS a-Si: TFT (hydrogenated amorphous silicon) or a PMOS organic device. Recently a-Si:H and pentacene PMOS TFTs have been integrated into complementary logic structures similar to CMOS. This, in turn, creates… Read More
