Embodiment Construction

[0071] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation methods, The method, steps, structure, features and effects thereof are described in detail below.

[0072] Please refer to Figure 1A and Figure 1B, which is a schematic diagram of a preferred implementation device of the present invention. Among them, the plurality of first (axial) sensors Y0-Yn and the plurality of second (axial) sensors X0-Xm are mutually overlapping sensors on a touch panel (not marked), and they are overlapped on multiple The overlapping area, and this part is an existing known structure, and will not be further described here. A signal unit 101 outputs a first signal to a plurality of first axial sensors Y0 -Yn, wherein the first signal includes a pulse-width modulation (PWM) signal. A subtractor 110, detecting a plurality of second axial sensors X0-Xm wherein two second axial sens...

Abstract

A method for inspecting the strips of a touch panel is disclosed. The method includes providing a first signal to a first driven first strip of a plurality of first strips and generating a plurality of continuous first differences according to signals on a plurality of second strips; providing the first signal to the first driven first strip and a second driven first strip of the plurality of first strips and generating a plurality of continuous second differences according to the signals on the plurality of second strips; and determining if there is a broken second strip between the first and second driven first strips based on the continuous first and second differences. Herein, the plurality of first and second strips intersect each other on the touch panel to form a plurality of intersecting regions.

Description

technical field [0001] The present invention relates to a touch panel detection method and device, in particular to a touch panel sensor (sensor; strip; line) disconnection detection method and device. Background technique [0002] Touch panels are now applied to many electronic devices. With the application requirements and technological innovations, the convenience brought by touch technology can be found from small portable electronic devices to large display panels. However, during the manufacturing process of the touch panel, the connection status of the sensor (sensor or strip) may fail due to the influence of many factors, that is, disconnection or poor contact, thereby affecting the production cost and product function. And how to detect whether the status of the sensor is disconnected from the touch panel and the precise position of the disconnected sensor to ensure the production quality and improve the production process should be pursued by today's touch technolo...
