Please refer to the first figure, which is a block diagram of a touch position processing method of a touch panel to which the present invention is applied. The touch position processing method of the touch panel of the present invention is applied to a touch panel 102, a touch integrated circuit 114, a main system end transmission interface 108, a main system processor 110, and a peripheral component 112; The touch integrated circuit 114 includes an analog-to-digital converter 104 and a touch-side transmission interface 106, but does not include any microcontroller or processing unit in the touch integrated circuit of the prior art. A host system 118 includes the primary system side transport interface 108, the host system processor 110, and the peripheral component 112.

Please refer to the second figure, which is a flowchart of the touch position processing method of the touch panel of the present invention; and please refer to the first figure at the same time. The touch position processing method of the touch panel of the present invention comprises the following steps:

S02: The analog digital converter 104 scans the touch panel 102 to obtain a class. Than the touch signal 202.

S04: The analog-to-digital converter 104 converts the analog touch signal 202 into a digital raw data 204.

S06: The analog-to-digital converter 104 transmits the digital raw data 204 to the touch-side transmission interface 106.

S08: The touch-end transmission interface 106 transmits the digital raw data 204 to the main system-side transmission interface 108.

S10: The primary system side transmission interface 108 transmits the digital raw data 204 to the primary system processor 110.

S12: The main system processor 110 converts the digital raw data 204 into a touch coordinate data 206 by using a touch coordinate algorithm.

S14: The main system processor 110 determines whether the touch coordinate data 206 is correct; if yes, proceeds to step S16; if not, proceeds to step S18. This step is because the main system processor 110 must be able to recognize when, for example, the user accidentally presses the palm on the touch panel 102.

S16: The main system processor 110 transmits the touch coordinate data 206 to the peripheral component 112. Finally, the process of this step ends.

S18: The main system processor 110 does not transmit the touch coordinate data 206 to the peripheral component 112. Next, the process proceeds to step S20.

S20: The main system processor 110 controls the analog-to-digital converter 104 to scan the touch panel 102 again to obtain the analog touch signal 202 and convert the analogy through the main system end transmission interface 108 and the touch end transmission interface 106. Touch signal 202 becomes the Digital raw data 204. Then it returns to step S06.

Moreover, when the whole system is powered on, the touch terminal transmission interface 106 and the main system side transmission interface 108 and the like are also registered to prepare for subsequent related events and behaviors.

The main system 118 can be, for example, but not limited to, using an Android operating system (Android), a Microsoft operating system (such as Windows Mobile System or Windows 8, etc.) or an Apple operating system; that is, the main system 118 can be applied to each The main system processor 110 can be, for example, but not limited to, converting the touch coordinate data 206 into a working system coordinate format and transmitting to the peripheral component 112.

The main system processor 110 can be, for example but not limited to, an advanced RISC machine (or abbreviated as ARM); wherein the reduced instruction set computer is generally referred to as a reduced instruction set computer (RISC).

The touch-side transmission interface 106 and the main system-side transmission interface 108 can be, for example but not limited to, a serial peripheral interface (hereinafter generally referred to as SPI), an internal integrated circuit (inter-integrated circuit, usually referred to as I 2 C), a universal serial bus (commonly referred to as USB) or a universal asynchronous receiver/transmitter (referred to as UART).

The main system processor 110 (for example, an ARM processor) replaces the microcontroller in the touch integrated circuit in the prior art, and the digital system raw data is processed by the main system processor 110. 204 becomes the touch coordinate data 206 Thereby, the efficiency of the touch can be improved, and the cost and power consumption are saved because the microcontroller in the touch integrated circuit is saved.

However, the above is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the equivalent changes and modifications made by the scope of the present invention should still be covered by the patent of the present invention.
