LCD panels

We provide a family of TFT-LCD integrated circuits for the control of small and large displays


Thin Film Transistor technology (TFT) is the base for all modern displays. They can be processed on various substrates, the most widely used being amorphous Silicon (aSi), Poly Silicon (polySi) and single Crystal Silicon (Si). Liquid Crystal Displays (LCDs) are formed by active matrices of TFT devices patterned in a configuration of rows and columns on which the transistors are connected and acting as switches. Each row of the matrix connects the gate of the TFT devices and each column of the matrix connects the drain terminal of the device while the source is connected to the storage capacitor of the LC pixel. Controlling the switching and the timing of the devices and the storage of the correct data voltage in each pixel is one of the main function of our LCD control chipset.

Advanced Silicon lcd panels

High-End LCD Controllers and Drivers
A family of High-voltage Drivers and Controllers for large and medium size flat panel displays used in cockpit flight navigation instruments. Within the same products portfolio, single line LCD panels are also used for selective fiber optic switches in telecommunication instruments. These high end applications require the highest circuits accuracy as well as the highest qualification standard in terms of vibration tests, temperature life cycles, ESD immunity and EMI compatibility.


Audio/Video LCD Controllers and Drivers
Our products also extend to Audio and Video applications where single chip all-in-one controllers are the only possible solution for such small size panels. Driven by the lack of space, our all-in-one controllers are specifically designed for Chip-On-Glass (COG) bonding where the fine output pads pitch is as low as 17um leading to the highest integration density with a typical fan-out of 1500 output pins.
