The invention discloses a touch control display module set, an electrical performance detection and electrical performance method of the touch control display module set. The touch control display module set includes a touch control display body and an auxiliary testing circuit; the touch control display body includes N capacitance electrode plates which are distributed according to a certain rule; the auxiliary testing circuit includes N switching units and M test lead-out pins; each switching unit is provided with an input end, an output end and a controlled end; the test lead-out pins include control pins and test pins; the input ends of the switching units are in one-to-one corresponding connection with the capacitance electrode plates; and the control pins and the test pines are connected with the controlled ends and output ends of the switching units respectively in a cross manner. With the electrical performance detection and electrical performance detection method of the touch control display module set provided by the technical schemes of the invention adopted, whether the electrical performance of the touch control display module set is abnormal can be detected accurately.
Description
technical field [0001] The present invention relates to the technical field of electronic measuring instruments and equipment, in particular to a touch display module and an electrical performance detection device and method for the touch display module. Background technique [0002] Capacitive touch displays have become an integral part of smart electronic devices. [0003] The existing capacitive touch display screen is assembled by a touch display module, a control chip and other components. In the production process, unqualified touch display modules are assembled with qualified control chips and other components, resulting in unqualified formed touch display screens. [0004] In this way, the qualified control chip and other components assembled with the unqualified touch display module are scrapped. Therefore, before the touch display module is assembled with the control chip and other components, the performance of the touch display module needs to be tested, so as ...
