Description

Technical Field

[0001] The present invention relates to the technical field of touch panel detection, and in particular to a system and method for testing touch panel functions. Background Art

[0002] Flexible Flat Cable (FFC) is a new type of data cable made of PET insulation material and extremely thin tinned flat copper wire, pressed together through a high-tech automated equipment production line. It has the advantages of being soft, easy to bend and fold, thin, small in size, simple to connect and disassemble, and easy to solve electromagnetic shielding (EMI).

[0003] A touchpad is an input device that uses the sliding of a finger on a smooth touchpad to move a cursor. It is easy for beginners to use and can be designed into ultra-thin notebook computers or keyboards because it is very thin. Moreover, it is very easy to maintain. The working principle of a touchpad is as follows: when the user's finger approaches the touchpad, the capacitance changes. The touchpad's own control IC will detect the change in capacitance and convert it into coordinates. The touchpad uses capacitive sensing to detect finger movement and is not sensitive to finger heat. When the finger touches the board, the electrostatic field on the board will change.

[0004] Currently, all laptops are equipped with touch pads. Touch pads are an input device widely used on laptops. They use the movement of the user's finger to control the movement of the pointer. The touchpad is used as a substitute for a USB mouse and is also used in some electronic products and equipment, such as audio and video equipment, digital equipment, etc. Among them, most touchpads are directly supplied by manufacturers, and the touchpads are not functionally tested, which easily leads to an increase in the defective rate of the touchpads. At present, the functional testing method for the touchpad unit is to assemble the touchpad unit and connect it to the laptop, and detect the function of the touchpad by the movement of the user's finger. However, this testing method is time-consuming and labor-intensive, and repeated assembly is prone to operational errors, resulting in reduced testing efficiency.

[0005] In view of this, it is necessary to provide a system and method for testing touchpad functions to solve the problems of current detection methods caused by manual finger movement detection, which are time-consuming and labor-intensive, cause operational errors, increase the defective rate of touchpads, and reduce detection efficiency.

If it moves, it means that the touchpad unit has the function of moving the pointer. If it does not move, the test fails. In addition, when the left or right button is pressed, it is determined whether the burning program is opened. If the burning program is opened, it means that the touchpad unit has the function of confirming the left and right buttons. If the burning program is not opened, the test fails. The system and method for testing the touchpad function of the present invention not only solve the problems of time and labor and operational errors, but also reduce the defective rate of the touchpad and improve the detection efficiency of the touchpad.
