Embodiment Construction

[0027] In order to facilitate the understanding of the present invention, the liquid crystal display module and its display detection circuit will be more fully described below with reference to the relevant drawings. The preferred embodiment of the liquid crystal display module and its display detection circuit is given in the accompanying drawings. However, the liquid crystal display module and its display detection circuit can be implemented in many different forms, and are not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the liquid crystal display module and its display detection circuit more thorough and comprehensive.

[0028] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be d...

Abstract

The invention relates to a liquid crystal display module and a display detecting circuit thereof. The display detection circuit comprises a module grounding line, a circuit board grounding line, a grounding module, a circuit board testing circuit, an auxiliary detecting line and a resistor R2, wherein the module grounding line is provided on the module body; one end of the circuit board groundingline is electrically connected to one end of the module grounding line, the other end of the circuit board grounding line is provided with a grounding interface, the circuit board grounding line is provided on a flexible circuit board connected to the module body; the grounding module is electrically connected to the circuit board grounding line, the grounding module is disposed on the flexible circuit board; one end of the circuit board test circuit is electrically connected to the other end of the module grounding line, and the other end of the circuit board testing circuit is provided witha test interface. Since the chip driving interface, the test interface, and the grounding interface are all disposed on the flexible circuit board, the module function tester is easily used for detection, thereby improving the detection efficiency of the display detection circuit.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display equipment manufacturing, in particular to a liquid crystal display module and a display detection circuit thereof. Background technique [0002] In order to improve the anti-static discharge capability of the liquid crystal display module, an anti-static discharge ground wire is added around the liquid crystal display module. When electrostatic discharge occurs, the static electricity will be released along the grounding wires around the module, so as to prevent the static electricity from damaging the internal lines of the module and causing poor display of the module. [0003] However, during the production process of the liquid crystal display module, there will inevitably be cracks on the glass edge of the module, or cracks on the flexible circuit board of the liquid crystal display module, which may cause an open circuit problem in the antistatic discharge circuit of the module...
