Abstract
A touch screen display and method for operating the same is provided. A touch screen display includes a display signal transmission interface, a storage module, a display control module, a display panel, a touch panel, and a touch control module. The display signal transmission interface receives display data from the host. The display signal transmission interface includes a display data channel. The display control module displays the received display data on the display panel. The touch panel receives and senses touches on the touch screen. The touch control module generates touch signals and transmits the touch signals to the host through the display data channel enabling bi-directional communication through a single interface.
Claims20
A touch screen display comprising:
- a display panel;
- a display signal transmission interface communicating with a host and configured to receive display data transmitted from the host, the display signal transmission interface comprising a display data channel;
- a display control module configured to display the display data on the display panel;
- a touch panel configured to receive applied pressure on the touch panel and sense the touch position of the applied pressure;
- and
- a touch control module configured to generate a touch signal according to the touch position and transmit the touch signal to the host through the display data channel.
A touch screen display comprising:
- a display panel;
- a display signal transmission interface communicating with a host and comprising a display data channel, display data transmitted from the host to the touch screen display through the display data channel;
- a display control module configured to display the display data on the display panel;
- a touch panel configured to sense touch position of the applied pressure on the touch panel;
- and
- a touch control module configured to generate a touch signal according to the touch position, the touch control module comprising an inter-integrated circuit interface, the touch control module further configured to transmit the touch signal to the host through an inter-integrated circuit bus connecting the display data channel to the inter-integrated circuit interface.
A bidirectional data transmission method employed in a touch screen display, the bidirectional data transmission method comprising:
