Embodiment Construction

[0029] refer to figure 1 , is a system block diagram of a testing system for a capacitive input device provided by the present invention. The capacitive switch shown in the figure is used to test an input device 100 , and the input device 100 has at least one capacitive switch 110 and a control module 120 . The control module 120 is used for monitoring the state of the capacitive switch 110 and receiving a switch signal corresponding to the switching state of the capacitive switch 110 . The input device 100 may further include an indication module 130 controlled by the control module 120 to display a switch state corresponding to the capacitive switch 110 .

[0030] In an exemplary embodiment, the capacitive switch 110 includes a plurality of sensors, such as a first sensor 110a, a second sensor 110b, a third sensor 110c, and a fourth sensor 110d, which constitute a touch sensing area , where the position of the sensors can be arranged according to the actual situation. In ...

Abstract

The invention provides a test system of a capacitive input device, which is used for testing the capacitive input device. The test system comprises a single chip, a display module and memory; wherein, the single chip is used for receiving a control signal output by a control module and responding to the control signal for outputting a test signal; the display module can respond to the test signal and display the test information that is corresponding to the test signal; the test information can be recorded in the memory. By adopting the test device provided by the invention, the unit under test can be tested quickly; the operation is simple and the test equipment is simplified.

Description

technical field [0001] The invention relates to a switch testing device, in particular to a testing system of a capacitive input device. Background technique [0002] The keyboard is the most commonly used and most important input device. Through the keyboard, English letters, numbers, punctuation marks, etc. can be input into the computer, so as to issue commands and input data to the computer. [0003] There are two types of conventional keyboards: mechanical keys and capacitive keys. The mechanical keyboard is the earliest structure adopted. Generally, the principle is similar to that of a metal contact switch to make the contacts turn on or off. Most cheap mechanical keyboards use copper springs as elastic materials. The copper sheets are easy to break and lose their elasticity. After a long time of use, the failure rate will increase, and now it has been basically eliminated and replaced by a capacitive keyboard. [0004] The capacitive keyboard is a keyboard based on...
