First embodiment
See also Fig. 2, the liquid crystal indicator 100 of present embodiment mainly includes a light guide module (light guide module) 110, one Liquid Crystal Module (LCD module) 120, one framework (frame) 130, plural conductive framework (bezel) 140 and a grounding assembly (groundingelement) 150.
Still as shown in Figure 2, framework 130 is to coat light guide module 110 and Liquid Crystal Module 120, and it can be used to fixedly light guide module 110 and Liquid Crystal Module 120.
According to the structure of the above-described liquid crystal indicator 100 of present embodiment as can be known, in a single day when having the buildup of static electricity phenomenon to produce among liquid crystal indicator 100 or the Liquid Crystal Module 120, electrostatic induced current just can conduct to conductive frame 140 via conductive layer 125, and then derived via grounding assembly 150, therefore, the intraware of liquid crystal indicator 100 or Liquid Crystal Module 120 just can not come to harm because of the existence of static release phenomenon.In addition, after liquid crystal indicator 100 manufactured finishing, it also can be passed to a high-pressure electrostatic and be done the safety test of electrostatic discharge protective (ESD), can learn so whether liquid crystal indicator 100 is qualified aspect electrostatic discharge protective.
Second embodiment
In the present embodiment, identical with first embodiment assembly all indicates with identical label.
See also Fig. 3, the liquid crystal indicator 100 ' of present embodiment mainly includes a light guide module 110, a Liquid Crystal Module 120, a framework 130, plural conductive framework 140 ' and a grounding assembly 150.
The difference of the present embodiment and first embodiment is to be the constructional difference of conductive frame, and remaining assembly structure and configuration mode are all identical with first embodiment, therefore, can be clearer understandable for asking description, its identical narration of Therefore, omited.
Still see also Fig. 3, can reach lightweight and purpose of thinness for making liquid crystal indicator 100 ', present embodiment reduces the thickness of conductive frame 140 ' (being half of thickness of the conductive frame 140 of first embodiment).Simultaneously, also be formed with a kink 141 on conductive frame 140 ', this kink 141 is to press down the conductive layer 125 that is contacted with Liquid Crystal Module 120, so conductive frame 140 ' is the conductive layer 125 that is connected in Liquid Crystal Module 120 by kink 141.
Similarly, in a single day when having the buildup of static electricity phenomenon to produce among liquid crystal indicator 100 ' or the Liquid Crystal Module 120, electrostatic induced current just can conduct to conductive frame 140 ' via conductive layer 125, kink 141, and then derived via grounding assembly 150, therefore, the intraware of liquid crystal indicator 100 ' or Liquid Crystal Module 120 just can not come to harm because of the existence of static release phenomenon.In addition, after liquid crystal indicator 100 ' manufactured the finishing, it also can be passed to a high-pressure electrostatic and be done the safety test of electrostatic discharge protective (ESD), can learn so whether liquid crystal indicator 100 ' is qualified aspect electrostatic discharge protective.
As for conductive frame 140 ' is partly made kink 141 with contacting of conductive layer 125, except above-mentioned lightweight and slimming are considered, still also because press down when being connected in conductive layer 125 when conductive frame 140 ', kink 141 can more positively form with conductive layer 125 and closely contact, and the overall construction intensity of conductive frame 140 ' is more promoted.
