Embodiment Construction

[0014] In the following, the specific implementation manners of the present invention will be further described in detail in conjunction with the accompanying drawings of the embodiments, so as to make the technical solution of the present invention easier to understand and grasp.

[0015] It can be seen from the conventional understanding that the piezoelectric touch screen is one of many types of touch screens, which includes an ITO film with N X-axis wiring X1~XN on the upper layer and an ITO glass with M Y-axis wiring Y1~YM on the lower layer. , the two layers of wiring are vertically interlaced to form M×N nodes. In the case of use, the user touches and presses the surface to make one or more nodes contact and connect, and recognizes the user's control requirements according to the pre-programmed conduction rules, and performs corresponding manipulations.

[0016] and see attached figure 1 As shown, when the linearity test is to be performed on the semi-finished touch sc...

Abstract

The invention relates to a linear testing method for a piezoelectric type touch screen. The linear testing method comprises the following steps: during a manufacturing process of a touch screen, testing connectivity of a Y axial wiring by unilaterally sliding and pressing an X axial wiring and testing connectivity of the X axial wiring by unilaterally sliding and pressing the Y axial wiring; after traversing X1, XN, Y1 or YM, confirming the piezoelectric type touch screen to be a qualified product according to a node signal displayed on a computer if the X axial wiring and the Y axial wiring are both connected; and confirming the piezoelectric type touch screen to be a rejected product, if one or both of the X and Y axial wirings are in bad connectivity. Compared with the prior art, the linear testing method has the advantages that the costs of labor and working hour are reduced and the testing efficiency is greatly improved.

Description

technical field [0001] The invention relates to a testing method for a touch control product, in particular to a fast linear testing method for a piezoelectric touch screen. Background technique [0002] The advent of touch panels has gradually replaced physical devices such as traditional buttons, keys, and switches, and has become a novel electrical control method. In recent years, touch panels have developed rapidly, and touch panels based on characteristics such as resistance, capacitance, and piezoelectricity emerge in an endless stream, among which piezoelectric touch panels are most widely used. Modern life is full of various electronic products, such as mobile phones, computers, PDAs, etc. Many of these electronic products are equipped with touch screens as interface devices for handwriting input or point-and-click input, especially when handwriting is input. For computers, a touch screen that can input continuous coordinate points is required, or other touch screen...
