Abstract

A data processing system having a display incorporating a touch screen, a constituent display driver (DDI) and method of display an image including a touch icon are disclosed. The DDI receives image data principally defining the display data defining the image on the display and separately receives touch icon image data defining the touch icon within the image. The image data and the touch icon image data are combined in the DDI to generate the display data provided to the display.

Claims

1-19. -19. (canceled)

20. A data processing system, comprising:

a touch screen panel configured to receive a touch input;

a host controller configured to generate an image data; and

a display driver integrated circuit (DDI) configured to generate a display data by combining the image data with a touch icon image data defining the touch icon image in response to the touch input.

21. The data processing system of claim 20, further comprising:

a touch screen controller (TSC) configured to receive a touch signal from the touch screen panel and generate a coordinate data identifying a location of the touch input on the touch screen panel,

wherein the host controller is further configured to receive the coordinate data and generate the touch icon image data in response to the coordinate data.

22. The data processing system of claim 21, wherein the display driver IC comprises:

a first memory storing the image data received from the host controller;

a second memory storing the touch icon image data received from the host controller; and

an image summing unit configured to receive and combine the image data from the first memory and the touch icon image data from the second memory.

23. The data processing system of claim 20, further comprising:

a touch screen controller (TSC) configured to receive a touch signal from the touch screen panel and generate a coordinate data identifying a location of the touch input on the touch screen panel; and

a graphics engine configured to receive the coordinate data and generate the touch icon image data in response to the coordinate data.

24. The data processing system of claim 20, further comprising:

a touch screen controller (TSC) configured to receive a touch signal from the touch screen panel and generate a coordinate data identifying a location of the touch input on the touch screen panel,

wherein the display driver IC (DDI) comprises;

a first memory storing the image data received from the host controller;

a second memory storing the touch icon image data; and

an image summing unit configured to receive and combine the image data from the first memory with the touch icon image data.

25. The data processing system of claim 24, wherein the DDI further comprises;

a driver configured to receive the combined image data and generate the display data.

26. The data processing system of claim 25, wherein the image summing unit comprises:

an address controller configured to receive and correlate the coordinate data with the touch icon image data received from the second memory to generate the movement of the touch icon image data; and

an image summing circuit configured to receive and combine the image data from the first memory and the touch icon image data from the address controller.

27. The data processing system of claim 26, wherein the DDI further comprises;

a driver configured to receive the combined image data and generate the display data.

28. The data processing system of claim 21, wherein the DDI and TSC are implemented as a single chip integrated circuit (IC).

29. A data processing system, comprising:

a display panel incorporating a touch screen panel configured to receive a touch input;

a host controller configured to generate a image data;

a display controller configured to generate a combined image data of the image data and a touch icon image data;

a first plurality of drivers arranged on one side of the display panel and configured to receive the combined image data and generate a display data, and a second plurality of drivers arranged on another side of the display panel.

30. The data processing system of claim 29, wherein each one of the first plurality of drivers is a source driver, and each one of the second plurality of drivers is a gate driver.

31. The data processing system of claim 29, wherein the display panel is a Liquid Crystal Display (LCD) panel or Plasma display panel (PDP).

32. The data processing system of claim 29, further comprising:

a touch screen controller (TSC) configured to receive a touch input from the touch screen panel and generate a coordinate data identifying a location of the touch input on the touch screen panel,

wherein the host controller is further configured to receive the coordinate data and generate the touch icon image data in response to the coordinate data.

33. The data processing system of claim 29, wherein the display controller comprises:

a first memory storing the image data received from the host controller;

a second memory storing the touch icon image data received from the host controller; and

an image summing unit configured to receive and combine the image data from the first memory and the touch icon image data from the second memory.

34. The data processing system of claim 29, further comprising:

a touch screen controller (TSC) configured to receive a touch signal from the touch screen panel and generate a coordinate data identifying a location of the touch input on the touch screen panel; and
