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...

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...
