Detailed explanation of the design challenges of multi-point capacitive touch screens
Multi- contact capacitive touch screens have and are continuing to change the way people interact with handheld devices and
bring many new operating experiences to people. From mobile phones to e-books, electronic writing pads, navigators, electronic
game consoles and laptops, all have abandoned the original touch buttons and are competing to choose multi-point capacitive touch
screens for human-computer interaction. In particular, the emergence of I-Phone and I-Pad has made multi-point capacitive touch
screens deeply rooted in the hearts of the people. However, the design of multi-point capacitive touch screens is not easy and readily available.
Strictly speaking, multi-point capacitive touch screen technology is not a fully mature technology. It is still a technology in the development stage
and is constantly being developed and improved. For designers of multi-point capacitive touch screens, they still face many design challenges.
This article introduces the design challenges of multi-point
capacitive touch screen design and how to use TTSP solutions to help designers face these challenges, making multi-point
capacitive touch screen design easier than ever.

design challenge

Design challenge one

The first challenge from multi-point capacitive touch screen design is how to convert the small mutual capacitance changes
due to finger touch into digital signals with sufficient resolution. We know that, generally speaking, multi-touch is based on the principle
of mutual capacitance sensing, and mutual capacitance is the parasitic capacitance at the intersection
of the transmitting sensing strip and the receiving sensing strip. This capacitance is very small, usually 0.2~4pF, and The change in mutual
capacitance caused by finger touch is even smaller. The detection of such tiny mutual capacitance changes not only requires a hardware detection
circuit that is highly sensitive to capacitance changes to convert weak analog power into digital signals, but also requires corresponding software for
control and coordination to ensure that the entire touch screen Each point has high enough sensitivity to finger touch signals.

Design challenge two

How to obtain a fast enough scan time is the second challenge in multi-point capacitive touch screen design. For a single-point touch screen
with M rows and N columns of sensing strips, using self-capacitance scanning, it only needs to scan M rows and N columns separately to calculate
and locate the coordinates of the finger on the touch screen based on the signals of each row and column. . The number of times it scans the sensor
strip is M+N times. When you use multi-contact mutual capacitance scanning, since it must be scanned at the intersection of rows and columns, the
number of scans is the number of MXN scans at the intersection. For a 3.2-inch screen with 10 rows and 20 columns, self-capacitance scanning only
requires 10+20=30 times, while mutual capacitance scanning requires 10X20=200 times. As the size of the touch screen
becomes larger and larger, the number of scans increases faster and faster. In order for users to have a better touch experience, it needs to scan the
screen at least 50 times per second. This means that the scanning and data processing time of each point must be less than 100us,
so as to ensure a fast enough response time. When the size of the touch screen is larger, the number of rows and columns will be larger, and this time will be shorter.
