Abstract

A method for transmitting touch panel data is provided. The method is adapted for transmitting coordinate data of at least a touch point being touched on the touch panel and includes the following procedures. The at least coordinate data is compressed. A serial data transmission interface command and a serial data transmission interface client address are appended in front of the compressed at least coordinate data, such that the compressed at least coordinate data is encapsulated into a serial transmission data packet. In addition, the serial transmission data packet is transmitted through a serial data transmission channel.

Claims8

Dependent claims

A method for transmitting touch panel data, adapted for transmitting coordinate data of at least one touch point being touched on a touch panel, the method for transmitting touch panel data comprising:

determining whether an amount of data of the coordinate data is greater than a data amount threshold;
compressing the coordinate data when the amount of data of the coordinate data is greater than the data amount threshold;
appending a serial data transmission interface command and a serial data transmission interface client address in front of the compressed coordinate data, such that the compressed coordinate data is encapsulated into a first serial transmission data packet;
transmitting the first serial transmission data packet through a serial data transmission channel;
and
selecting not to compress the coordinate data when the amount of data of the coordinate data is less than the data amount threshold.
