Touch/Display Integration (TDDI)

Performance and efficiency remain key differentiators in touchscreens for markets including smartphones, tablets and automotive. With Synaptics state-of-the-art TDDI technology -- in which both the underlying display driver and touch sensor are one chip -- device displays can have sensing designed atop or directly into one of many different layers of the touchscreen cell, or layers, of the touchscreen.

With on-cell integration, the touch sensor matrix is built directly onto the display’s cell, atop of the color filter glass. In addition to being cost-effective and dependable, on-cell designs are also a viable choice for active-matrix organic light-emitting-diode displays, as well as for larger, and curved or flexible displays when used with jumper-less, metal-mesh sensors.

Synaptics display integration technology enables both full and hybrid in-cell integration -- design approaches that enhance image quality by optimizing cell efficiency and in certain cases reducing the number of layers in the display. Full in-cell designs have the additional advantage of requiring only a single flexible printed circuit connector, thus reducing costs and improving reliability.

Synaptics touch and display driver integration, or TDDI, improves displays' design and manufacturability. When combined with full in-cell designs, TDDI provides for display layers, superior touch performance, lower costs, reduced power consumption, accelerated time to market, and greater reliability

TDsync™: Eliminating Display Noise

Synaptics TDsync technology eliminates display-induced noise by coordinating and synchronizing display updates and touch sensing functions, resulting in a more responsive and reliable touchscreen and superior user experience.
