Problems solved by technology

However, there is no innovative method for checking the conductive connection between the touch panel and the flexible substrate
Therefore, even if the inspection of the electrode signal wiring of the touch panel is passed, but there is a poor conduction connection between the touch panel and the flexible substrate, even if an electrical signal is supplied from the motherboard, the touch panel may not be able to accurately detect the coordinates.

Embodiment Construction

[0024] The best mode for carrying out the present invention will be described. First, a touch panel and a connection substrate to be inspected by the connection inspection device of the present invention will be briefly described. The touch panel TP has: X-axis electrode wiring x( figure 1 are the labels x1 and x2), and the Y-axis electrode wiring y ( figure 1 y1 and y2 ), a plurality of X-axis electrode wiring x and Y-axis electrode wiring y form the sensor area of ​​the touch panel TP. The X-axis electrode wiring x and the Y-axis electrode wiring y are formed of, for example, an ITO (indium tin oxide) film or the like.

[0025] The sensor area functions as an input terminal by detecting a user's touch position on the sensor area through the X-axis electrode wiring x and the Y-axis electrode wiring y forming the sensor area. exist figure 1 2 shows the outline of the touch panel TP, and two X-axis electrode wirings x and two Y-axis electrode wirings y are drawn. The numbe...

Abstract

The invention provides a connection detector used for determining the connecting state between a touch panel and a flexible substrate connected with the end of the touch panel; terminals in wiring connection with 2 X-shaft electrodes are selected from the flexible substrate, and the terminal in wiring connection with the Y-shaft electrode is selected as the connection inspection object; the pair of X-shaft electrode wires serve as power supply electrodes for AC signals, and the connection inspection object terminal from the flexible substrate is detected to obtain detection signal; the connecting state can be determined according to the detection signal.

Description

technical field [0001] The present invention relates to an inspection device used for touch panels and the like, and relates to a connection inspection device for checking the conduction state between a touch panel and a flexible substrate conductively connected to an end portion of the touch panel. Background technique [0002] In recent years, touch panel technology has attracted attention as an input terminal used as a graphical user interface in mobile phones such as smartphones, tablet PCs, and the like. This touch panel technology is generally configured such that a plurality of electrode wirings are arranged in each of the X-axis direction and the Y-axis direction, and the coordinates of the position touched by the user can be detected. [0003] Generally, in a large-sized touch panel used in a tablet PC, as a detection method, position information is often detected by an electrostatic capacity method. In such a touch panel, for the wiring arranged in the X-axis dire...
