Problems solved by technology

However, when the fixed touch surface becomes larger, its scan time becomes longer
If the scan time is too long, it may not be possible to detect the movement track of a touch object such as a finger; if the resolution is reduced to shorten the scan time, it may not be possible to identify multiple adjacent touch objects
Furthermore, when the fixed touch surface becomes larger, the response time of the known touch sensing device is also likely to be longer due to the increase in the amount of data processing, and may not be able to keep up with the moving speed of the touch object.
[0003] In addition, since some application programs (APP) only provide touch operation functions in a partial area of ​​a display area, the known touch sensing device still scans the entire touch surface repeatedly with a fixed resolution in this case. , making the entire scanning process appear clumsy and inefficient, which also needs to be improved

Abstract

An adaptive sensing apparatus, including: a sensor array, having N sensing points, wherein N is a positive integer; a driver unit, coupled with the sensor array; and a control unit, coupled with the driver unit; wherein the control unit has at least one adaptive sampling modes for controlling the driver unit to drive the sensor array and derive M sensed data, wherein M is a positive integer and M<N.

Description

technical field [0001] The present invention relates to a sensing device, in particular to an adaptive sensing device, which can provide different adaptive sampling modes according to different touch operation requirements, so as to reduce the amount of sensing data. Background technique [0002] Conventional touch sensing devices generally repeatedly scan a fixed touch surface with a fixed resolution. However, when the fixed touch surface becomes larger, its scanning time will become longer. If the scanning time is too long, it may be impossible to detect the movement track of a touch object such as a finger; if the resolution is reduced to shorten the scanning time, it may be impossible to identify multiple adjacent touch objects. Furthermore, when the fixed touch surface becomes larger, the response time of the known touch sensing device is likely to be longer due to the increase in the amount of data processing, and may not be able to keep up with the moving speed of th...
