Integrated Display Driver with Readout Function for Touch Screen


Samsung announced today the development of the world's first mobile display driver IC (DDI) that combines the display driver and readout functions for touch-sensor-embedded display panels.

Today, LCD panel with touch screen need an additional panel that contains touch sensors mounted on the top of the LCD panel. This requires special assembly of extra components and consumes additional volume and weight. Samsung's new DDI device enables the AMLCD itself to be touch-sensitive eliminating the need for extra layer of the touch screen panel layer. This is done through the introduction of a touch-sensitive sensor into the pixel. This approach enables designers to dispense with the separate touch panel, raising light transmissivity, improving brightness and providing sharper on-screen images.

''Designers can get an ultra-thin touch screen by combining our new DDI with an LCD that has embedded touch sensors. This method will accelerate the process of developing lighter and slimmer mobile products that feature a touch screen.'' says Dr. Myunghee Lee, vice president of the Advanced DDI Design Team at System LSI Division of Samsung Electronics, Co.
