Wherein, the chip controller 150 transmits a control command to the proximity controller 110 and the display controller 130 simultaneously by using the communication format of the bus. If the custom communication format is serial communication, and the content of the packet format is: address, control command, packet data or continuous packet data, where the address can be 4 bits, the control command is 8 bits, and the packet data is 8 bits, However, the packet data is 8bit and can be continuous packet data.

The control command is set to binary 00000010, wherein the 7th bit is 1 to represent the read command, and what is to be read is at least one proximity data generated by the sensing controller 110 according to the proximity of at least one object. To continuously read three proximity data, the chip controller 150 first transmits the binary packet format to the proximity controller 110 in the form of 0001-00000010, and after the control command is transmitted via the bus, wait and receive 00000001-00000010-00000011 for three consecutive Proximity information of the pen.

For example: the address of the display controller 130 can be binary 0011, and the control command is set to binary 00000001, which means to start the display controller 130 to control the display panel 20, and the packet format of the chip controller 150 to start the display controller 130 is 0011- 00000001. To write the display control data to the display controller 130 , the control command is 00000100, and the 6th bit thereof is 1, which means that the display control data is to be written to the display controller 130 .

The control instruction is set to binary 00010000, and its 4th bit is 1, which means that the display microcontroller 132 is to be activated to control the sensing controller 110 to control at least one proximity sensing unit 52 . Therefore, the chip controller 150 needs to activate the display microcontroller 132 to control the sensor controller 110 with a packet format of 0001-00010000. If the display microcontroller 132 is to be activated to control the display panel 20 and the sensor controller 110 at the same time, the packet format is 0001-00010001, so bits 0 to 3 of the control command represent display panel function options, and bits 4 to 7 represent proximity function options.

The chip controller 150 has a bus, connected to the sensing microcontroller 112 through the bus, for controlling the sensing microcontroller 112 and receiving at least one proximity data sensed by the sensing microcontroller 112, and controlling the sensing microcontroller 112 Thus, the display controller 130 generates a voltage driving force, and the display unit determines the luminous brightness according to the voltage driving capability.

Example 1: The address of the sensing microcontroller 112 can be binary 0001, and the control command is set to binary 00000001, which means that the sensing microcontroller 112 is to be activated to control the display controller 130 to display the display panel 20, so the chip controller 150 The packet format for enabling the sensing microcontroller 112 to control the display controller 130 is 0001-00000001. The control instruction is set to binary 00010000, and the 4th bit being 1 means that the proximity microcontroller 112 is to be activated to control at least one proximity sensing unit 52 . Therefore, the chip controller 150 starts the proximity microcontroller 112 to control the packet format of at least one proximity sensing unit 52 to be 0001-00010000. If the proximity microcontroller 112 is to be activated to control at least one proximity sensing unit 52 and the display controller 130 at the same time, the packet format is 0001-00010001, so bit0 to bit3 of the control command represent touch function options, while bit4 to bit7 represent proximity Feature options.

Example 2: The chip controller 150 uses the communication format of the bus to read the proximity data in the sensing microcontroller 112 . For example: the address of the sensing microcontroller 112 can be binary 0001, and the control command is set to binary 00100010, and the packet data is set to 00000100, the 6th bit being 1 means that four pieces of proximity data are to be read. Therefore, to read four consecutive proximity data in the sensing microcontroller 112, the chip controller 150 can first send the packet format to the sensing microcontroller 112 as 0001-00100010-00000100, and wait for and receive 000000001- 00000010-00000011-00000011 and other four packets of data.
