Embodiment Construction

[0019] The specific implementation manners of the present invention will be described in further detail below with reference to the accompanying drawings. Hereinafter, the same reference numerals denote the same parts or elements.

[0020] figure 1 It shows a schematic structural view of the touch panel testing device according to the present invention to perform panel cell segment testing. As mentioned above, the in-cell touch panel generally integrates the touch function directly into the manufacturing process of the panel, without adding a layer of touch glass substrate on the array substrate.

[0021] refer to figure 1 , The touch panel testing device includes a touch panel 11, a plurality of test points 13, a plurality of touch sensing lines 15 and a current source (not shown in the figure). Wherein, all the touch sensing lines are parallel to each other. The touch panel 11 is divided into multiple regions according to one or more of the touch sensing lines 15, for ex...

Abstract

The invention discloses a testing apparatus of a touch panel, which at least comprises a touch panel, a plurality of touch induction lines which are arranged on the touch panel, a plurality of test points, and a current source which is electrically connected to one of the plurality of test points, wherein each test point is electrically connected to one or more touch induction lines; the one or more touch induction lines which are connected with the test points divide the touch panel into a plurality of regions; and when any one of the plurality of regions is pressed, the current source acquires induction current flowing over the test points. The testing apparatus of the touch panel can rapidly diagnose whether sensing components in the touch panel work normally by utilizing the value of the induction current when pressing the touch panel, and avoids loss of raw materials in subsequent processing due to abnormal work of the sensing components.

Description

technical field [0001] The invention relates to a touch panel testing technology, in particular to a testing device for an in-cell touch panel. Background technique [0002] Currently, with the rapid development of science and technology, more and more electronic devices adopt touch-type human-computer interaction interfaces to facilitate users to flexibly select corresponding application functions. For example, in daily life, touch operation behavior has deeply penetrated into many application fields such as mobile phones, navigation devices, and portable handheld game consoles. With the enlargement of touch panel size, this touch interface design can also be applied to retail stores, ticket vending machines, information kiosks, education and training fields, etc. [0003] In the prior art, from the point of view of touch sensing design, touch panels can be divided into two types: traditional on-cell touch panels and new in-cell touch panels. kind. Different from the plu...
