The invention provides a detection method for an enhanced 3D detection module. The enhanced 3D detection module comprises a plurality of touch control units, a plurality of pressure sensing units and a signal processing circuit, wherein the plurality of touch control units are used for sensing positions of touch control points; the plurality of pressure sensing units are used for sensing pressing force. The detection method comprises the following steps: S1, providing a touch control scanning pulse to the plurality of touch control units, and providing q pressure scanning pulse to at least two pressure sensing units; S2, generating touch control signals by the plurality of touch control units according to the positions of the touch control points sensed by the touch control scanning pulse, and generating an overlapped pressure signal by the at least two pressure sensing units according to the pressing force sensed by the pressure scanning pulse; S3, judging the position and the pressing force of at least one touch control point by the signal processing circuit according to the overlapped pressure signal and the touch control signal. A driving method for a display panel with a 3D detection function has the advantages of being high in detection precision, good in anti-noise property and the like.
Description
[0001] 【Technical field】 [0002] The invention relates to a detection method, in particular to a detection method of an enhanced 3D detection module with touch point detection and pressure detection. [0003] 【Background technique】 [0004] With the development of touch technology, most of the existing industrial electronic devices and consumer electronic devices adopt display panels with touch function. During operation, the electronic device performs a specific operation by detecting the position of the touch point. For the detection of touch points, whether it is a capacitive screen or a resistive screen, they all use different principles to determine the two-dimensional coordinates of the touch point on the display panel, and establish a two-dimensional coordinate system (X, Y) on the surface of the display panel. ), the detection of the touch point is equivalent to determining the position of the touch point in the X-axis direction and the position in the Y-axis directio...
