Description

technical field [0001] The present invention relates to a display card device, and in particular to a display card with a touch screen function. Background technique [0002] With the advancement and popularization of computer technology, the keyboard and mouse have become the information input devices with the highest acceptance by the general public. Rise. [0003] Generally, the common resistive touch screen is basically a structure of film and glass. When touching, the ITO on the lower layer of the film will touch the ITO on the upper layer of the glass, and a message will be transmitted through the sensor, and then sent from the controller to the computer. On the terminal, the X and Y values ​​converted to the screen by the driver are used to complete the action of clicking and present on the screen. [0004] The system architecture that traditionally uses a touch screen is shown in Figure 1. The host computer 100 has a VGA card 106 , which converts image data obtain...
