Description
Technical field
It the utility model is related to cover plate field, more particularly to a kind of diaphragm and patch cuticula for cover plate porose area.
Background technology
One end of usual cover plate can be designed with IR holes (infrared induction lamp hole), front camera hole and LED hole.Because of IR
Hole, shooting head bore and LED hole need transmitted light to sense and the operating that works, therefore porose area does not allow the dirt such as foreign matter, dirty occur
Contaminating thing hinders light to pass through, thus cover plate needs to cover one layer of protection at the back side of cover plate in production process and turnover transportation
Film is to protect porose area not to be contaminated.
A colored dyestripping ear handle can be reserved in product periphery side when being generally designed to porose area diaphragm, it is made
With one：Facilitate dyestripping operation, it acts on two：Color handle can distinguish cover plate back side porose area region whether there is overlay film.But there is part production
Product are special because designing, and periphery can be disturbed assembling such as reserved handle, thus can not set reserved handle, and is not provided with handle
Diaphragm water white transparency itself, can not also distinguish porose area whether there is overlay film from cover plate front through porose area, cause should overlay film and
Leak the situation of overlay film or be that should remove the phenomenon for occurring leaking dyestripping when pore membrane carries out down one of manufacturing procedure, the production after assembling
Product need to do over again or scrap.Therefore, a kind of scheme is needed in the prior art, to avoid the leakage patch of the diaphragm without reserved handle and leakage
Tear phenomenon.
