Large PCAP screen with multiple touch controller ASICS with interleaved receiver connections

A method, for a first touch controller application-specific integrated circuit (ASIC), comprising:

• determining a first subset of coarse touch coordinate data based on first connections between receiver circuits and a first subset of touchscreen electrodes of a projected capacitive (PCAP) touchscreen, wherein the first connections are interleaved with second connections, wherein the second connections are between receiver circuits of a second touch controller ASIC and a second subset of touchscreen electrodes of the PCAP touchscreen;
• and
• transmitting the first subset of coarse touch coordinate data to a processor, wherein the processor receives a second subset of coarse touch coordinate data from the second touch controller ASIC that determines the second subset of coarse touch coordinate data based on the second connections, and wherein the processor determines final touch coordinates based on the first subset of coarse touch coordinate data and the second subset of coarse touch coordinate data.

A non-transitory computer readable medium having stored therein one or more instructions that, when executed by one or more processors, cause the one or more processors of a first touch controller application-specific integrated circuit (ASIC) to perform operations, the operations comprising:

• determining a first subset of coarse touch coordinate data based on first connections between receiver circuits of the first touch controller ASIC and a first subset of touchscreen electrodes of a projected capacitive (PCAP) touchscreen, wherein the first connections are interleaved with second connections, wherein the second connections are between receiver circuits of a second touch controller ASIC and a second subset of touchscreen electrodes of the PCAP touchscreen;
• and
• transmitting the first subset of coarse touch coordinate data from the first touch controller ASIC to a processor, wherein the processor receives a second subset of coarse touch coordinate data from one or more processors of the second touch controller ASIC that perform operations to determine the second subset of coarse touch coordinate data based on the second connections, and wherein the processor determines final touch coordinates based on the first subset of coarse touch coordinate data and the second subset of coarse touch coordinate data.
