With the rapid development of the panel display industry, displays of various shapes and sizes are widely used in various fields such as industry, security, entertainment, and office.

Watches, mobile phones, tablets, computers, TVs, etc. have gradually evolved into "one screen" in the process of intelligence, and almost all operations of users are completed by clicking and touching the screen.

Therefore, before the equipment leaves the factory, the touch panel test is particularly important.

Generally speaking, touch operation can be divided into three modes:
single touch
virtual multi-touch
True Multi-Touch

Touch methods and gesture recognition include:

Double Tap
Drag and Drop
Pan/Flip/Rotate

zoom in/scroll

During the testing process, we need to use equipment to simulate these hand movements to meet product quality inspection standards.

The precise force control and positioning functions of the linear voice coil motor are very suitable for this kind of test.

Goal Tech linear voice coil motor is a highly integrated design, with a minimum thickness of 10mm, which greatly saves the internal space of the device, which is more conducive to the realization of multi-motor matrix combination arrangement and simulates multi-point operation of fingers.

The motor also supports programmatic setting of speed, acceleration and force control. After setting the corresponding parameters, the motor can work like a finger, and perform corresponding operations such as double-clicking and dragging on the display screen of mobile phones, tablets and other devices.

At present, the mainstream in the market is the capacitive touch screen. When the output shaft of the motor touches the screen, the capacitance will change, so that the touch chip detects the relevant operation and sends a signal to the CPU immediately. After the CPU obtains the touch coordinates, it can send a feedback.

Goal Tech linear voice coil motor adopts bus-type control mode, which supports real-time signal transmission of multiple motors; the synchronization error of motor control is small, the data delay is low, and more accurate data can be obtained; the force control accuracy of ±0.01N, the straight line of ±0.002mm The repeated positioning accuracy is at the leading level in the industry, which can help manufacturers to conduct more precise tests.

Goal Tech linear voice coil motor can perfectly realize multiple operations in touch panel testing, which is the key to improving testing efficiency and reliability, helping to improve product production yield and improve business efficiency.
