Abstract

An electronic apparatus with a touch panel including a host controller, an interface unit, and a touch panel control unit is provided. The host controller is used to control an electronic apparatus implemented with the host controller. The touch panel control unit is coupled to the host controller through the interface unit. The host controller transmits an updating information to the touch panel control unit with a format of the interface unit, in which the updating data is used to update the touch panel control unit. The touch panel control unit decodes the updating data to accordingly update.

Claims

1. An electronic apparatus with a touch panel, comprising:

a host controller, for controlling the electronic apparatus;

an interface unit; and

a touch panel control unit, coupled to the host controller through the interface unit,

wherein the host controller transmits an updating data to the touch panel control unit in a format of the interface unit for updating the touch panel control unit, and the touch panel control unit decodes the updating data to accordingly update.

2. The electronic apparatus with the touch panel as claimed in claim 1, wherein the touch panel control unit transmits a touch testing data to the host controller through the interface unit for outputting, so as to perform analysis and adjustment.

3. The electronic apparatus with the touch panel as claimed in claim 1, wherein the host controller comprises:

a data decision control unit; and

a bus command control unit,

wherein the data decision control unit receives and decides an input data, and transmits a decided data to the touch panel control unit through the buss command control unit,

and the data decision control unit reads a sensing data from the touch panel control unit through the bus command control unit for outputting.

4. The electronic apparatus with the touch panel as claimed in claim 1, wherein the host controller comprises:

a data decision control unit;

a memory unit; and

a bus command control unit,

wherein the data decision control unit receives and decides an input data, and stores a decided data into the memory unit,

the bus command control unit read the decided data from the memory unit, and transmits it to the touch panel control unit,

and the data decision control unit reads a sensing data from the touch panel control unit through the bus command control unit for outputting.

5. The electronic apparatus with the touch panel as claimed in claim 1, wherein the touch panel control unit comprises:

a bus command control unit, coupled to the host controller through the interface unit;

a memory unit, coupled to the bus command control unit, for storing an operation information, wherein the operation information comprises touch related data; and

a touch sensor control unit, coupled to the bus command control unit and the memory unit, wherein the memory unit obtains at least a part of the operation information, and outputs a touch sensing data to the bus command control unit.

6. The electronic apparatus with the touch panel as claimed in claim 1, wherein the bus command control unit comprises an interface decoder, and performs updating if received data comprises the updating data.

7. The electronic apparatus with the touch panel as claimed in claim 6, wherein the updating data is inputted through setting addresses of the interface unit, and the interface decoder performs decoding through a data protocol.

8. The electronic apparatus with the touch panel as claimed in claim 1, wherein the host controller comprises a bus command control unit for receiving the updating data and transmitting it to the touch panel control unit,

wherein the touch panel control unit comprises:

a bus command control unit, coupled to the host controller through the interface unit, wherein the bus command control unit receives and decides the updating data to obtain an operation information;

a memory unit, coupled to the bus command control unit, for storing the operation information, wherein the operation information comprises touch related data; and

a touch sensor control unit, coupled to the bus command control unit and the memory unit, wherein the memory unit obtains at least a part of the operation information, and outputs a touch sensing data to the bus command control unit.

9. A method for updating operation information of a touch panel, for integrating an electronic apparatus with a touch panel, wherein a touch panel control unit of the touch panel is coupled to a host controller through an interface unit, and the method for updating operation information of the touch panel comprising:

transmitting a touch panel updating data from the host controller to the touch panel control unit through the interface unit; and

updating the operation information of the touch panel control unit according to the touch panel updating data.

10. The method for updating operation information of the touch panel as claimed in claim 9, wherein the touch panel control unit identifies the touch panel updating data through setting addresses.

11. The method for updating operation information of the touch panel as claimed in claim 9, wherein the touch panel control unit decodes the touch panel updating data according to a data protocol.
