TOUCH SCREEN DISPLAY DEVICE

摘要

Rather than crowding all functionalities into a single monolithically integrated circuit and thus causing concentration of power dissipation, there is provided a touch screen display device in which a multifunctional smart IC is separated from a simplified display driver circuit. The smart IC includes a logic unit for driving a touch screen panel and a logic unit for driving a display panel. The touch screen display device includes not only the touch screen panel, the display panel, the simplified display driver circuit and the smart IC but may further optionally include a controllable power supply that is controlled by the smart IC. The smart IC includes a first logic unit for driving the touch screen panel and a second logic unit for driving the display panel. The display driver circuit is coupled to receive pre-processed display data and a driving synchronization signal from the second logic unit of the smart IC.

1. A touch-responsive and image displaying device, comprising:
a touch screen panel or layer; a display panel or layer; a smart IC including a first logic unit configured to control and/or drive the touch screen panel/layer and a second logic unit configured to control and/or drive the display panel/layer; and a display driver which is then sally distanced from the smart IC and is configured to receive from the second logic unit, processed display data that has been processed by the second logic unit, the display driver being configured to also receive from the second logic unit, a driving signal for synchronizing driving of the display panel.
