Integrated Device Technology, provider of mixed-signal semiconductors, has launched a touch screen controller IC. It is has single layer and multi touch screen.
IDT's Single Layer Multi Touch Sensor
It can be used without cross-over isolation points, making it a cost-effective and high performance device that can be used in handsets, personal navigation systems and handheld gaming consoles that have screen sizes of less than 5inches. The IDT LDS7000 and LDS7001 deices are full resolution touch screen controller ICs. They have up to 30 and 35 sensor channels respectively. Both work at a 8ms data rate, ensuring rapid response to touch inputs. The IDT LDS7000 family removes extra multi touch sensing for precise X and Y coordinates in a dual touch mode. This feature makes it suitable for applications where host interrupted movements are used to identify varied products. The device provides noise rejection performance so that it does not need an external shield, making it cost-effective.
They provide local support for a 10-bit resolution (1024 x 1024) and can scale X and Y touch values, making them flexible for use in applications of varied resolution LCD and AMOLED panels. Backlight illumination is enhanced, and its low consumption of power increases its battery life making it ideal for handheld consumer electronics.
