Problems solved by technology
With the development of multi-touch technology of touch screen devices, in the case of multi-touch, if this communication method in the prior art continues to be used, each touch point corresponds to a data packet, when there are multiple touch points , it is necessary to generate a plurality of data packets occupying the same fixed length, so that when the touch screen device communicates with the computer, each communication data packet will occupy the same transmission time. The refresh rate is relatively low, and the user experience effect is not good

Embodiment Construction
[0029] Referring to Fig. 1, it is a flow chart of the touch screen device of the present invention sending a communication data packet to a computer, including steps:
[0030] S101. The touch screen device generates a communication data packet according to a predetermined format according to the touch information of each touch point detected by it within a scanning cycle (for example, 1 / 60 second or less), the touch information includes the touch point of each touch point trigger event information;
[0031] Wherein, the above-mentioned communication data packet includes the function information triggered by each touch point, and may also include the position coordinate information of each touch point, the status information of the function triggered by each touch point, and the width information of each position coordinate. In addition, the communication data The package may also include verification information generated according to a predetermined format to verify the corre...

The invention discloses a method and a device by which a touch-screen device can communicate with a computer; the technical proposal is the data of at least one contact point detected in the scanning cycle can be packaged into a communications data package which then can be sent to the computer; for the data of at least one contact point detected in the scanning cycle is stored in the communications data package, the length of the communications data package can change with different contact points, so that the time for transmitting the communications data package can be shortened under the condition of a plurality of contact points, thereby improving the touch refresh rate of the touch-screen.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a method and a device for communicating between a touch screen device and a computer. Background technique [0002] In various touch screen devices in the prior art, when it communicates with a computer, it usually generates a data packet that mainly includes the coordinate information of the touch point and the triggered function information every time a touch point is detected. It has a fixed length and sends the fixed-length data packet to the computer. With the development of multi-touch technology of touch screen devices, in the case of multi-touch, if this communication method in the prior art continues to be used, each touch point corresponds to a data packet, when there are multiple touch points , it is necessary to generate a plurality of data packets occupying the same fixed length, so that when the touch screen device communicates with the computer, each communi...
