Description

触控面板及移动终端
本申请要求于2016年10月27日提交中国专利局、申请号为201610955214.3、发明名称为“触控面板及移动终端”的中国专利申请的优先权，上述在先申请的内容以引入的方式并入本文本中。
技术领域
本发明涉及液晶显示技术，尤其涉及一种触控面板及移动终端。
背景技术
现有的显示面板只具有显示功能，如果要增加压力触控功能，需要外挂压力触控单元，现有的显示面板中的力感应导电层和中框之间会存在一定的空气间隔，以形成电容。而电容对力感应层和中框之间的间距比较敏感，稍微形变就会造成电容的较大变化，严重影响触控功能的实现。
例如当移动终端跌落或者收到碰撞时，力感应导电层和中框之间的空气间距会发生变化，触控功能可能会失效。
发明内容
本发明提供一种触控面板和移动终端，能够防止因跌落和碰撞发生的触控功能失效现象。
本发明提供一种触控面板，力感应导电层、间隔层和固定金属层，所述间隔层位于所述力感应导电层和所述固定金属层之间，所述力感应导电层和所述固定金属层之间形成电容，所述间隔层填充弹性绝缘材料。
其中，所述间隔层由所述弹性绝缘材料填满。
其中，所述间隔层包括相互隔开的多个间隔部，所述间隔部由所述弹性绝缘材料制成。
其中，还包括液晶模组和背光模组，所述液晶模组和所述背光模组依次层叠在所述力感应导电层上，所述固定金属层位于所述力感应导电层的背离所述背光模组的一侧。
其中，还包括液晶模组和背光模组，所述液晶模组和所述背光模组依次层叠在所述间隔层上，所述力感应导电层形成在所述液晶模组中。
其中，所述力感应导电层包括基底以及导电图案，所述导电图案设置于所述基底上。
其中，所述基底为FPC板或者PET板。
其中，所述间隔层的厚度0.1mm至2mm，所述力感应导电层的厚度为30nm至100nm。
其中，还包括盖板，所述盖板设置在所述液晶模组的背离所述背光模组的一侧。
本发明还提供一种移动终端，包括如前述任一项所述的触控面板。
相较于现有技术，根据本发明的触控面板中，力感应导电层和固定金属层之间的间隔层填充弹性绝缘材料，当手指按压时，由于弹性绝缘材料的弹性特性，力感应导电层仍然能够产生形变，根据按压前后的电容变化，进而能够推算出压力值以及按压的位置坐标，从而能够实现压力触控的功能，并且当触控面板发生跌落碰撞时，间隔层中填充的弹性绝缘材料能够起到有效的缓冲作用，从而能够有效地防止固定金属层的形变，进而能够防止力感应导电层和固定金属层之间的距离发生变化，因此能够防止触控面板的失效。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例一
参照图1和图2，根据本发明的第一实施例的触控面板1包括盖板101、液晶模组102、背光模组103、力感应导电层104以及固定金属层105，其中，盖板101设置在液晶模组102的背离背光模组103的一侧，而液晶模组102和背光模组103依次层叠在力感应导电层104上，固定金属层105位于力感应导电层104的背离背光模组103的一侧，固定金属层105例如为触控面板1的金属中框，力感应导电层104和固定金属层105之间形成电容，并且力感应导电层104和固定金属层105之间设有间隔层106，该间隔层106填充有弹性绝缘材料。
在本实施例中，间隔层106由弹性绝缘材料完全填满，优选地，弹性绝缘材料可以是泡棉、硅胶或者橡胶，由于间隔层106填充的是弹性绝缘材料，因此力感应导电层104和固定金属层105之间仍然能够形成电容，在图2中，当手指按压盖板101时，由于弹性绝缘材料的弹性特性，力感应导电层104仍然能够产生形变，根据按压前后的电容变化，进而能够推算出压力值以及按压的位置坐标，从而能够实现压力触控的功能，并且当触控面板1发生跌落碰撞时，间隔层106中填充的弹性绝缘材料能够起到有效的缓冲作用，从而能够有效地防止固定金属层105的形变，进而能够防止力感应导电层104和固定金属层105之间的距离发生变化，因此能够防止触控面板1的失效。
进一步地，力感应导电层104包括基底(未示出)和导电图案(未示出)，基底为FPC(Flexible Printed Circuit，柔性电路板)板或者PET(Polyethylene-terephthalate，聚对苯二甲酸乙二醇酯)板，而导电图案由金属铜或者银制成， 导电图案通过喷溅、印刷、黄光的方式形成，优选地，力感应导电层104的厚度为30nm至100nm。因此，力感应导电层104的厚度较小，对触控面板1的厚度影响较小。
实施例二
参照图3和图4，根据本发明的第一实施例的触控面板2包括盖板201、液晶模组202、背光模组203、力感应导电层204以及固定金属层205，其中，盖板201设置在液晶模组202的背离背光模组203的一侧，而液晶模组202和背光模组203依次层叠在力感应导电层204上，固定金属层205位于力感应导电层204的背离背光模组203的一侧，固定金属层205例如为触控面板2的金属中框，力感应导电层204和固定金属层205之间形成电容，并且力感应导电层204和固定金属层205之间设有间隔层206，该间隔层206填充有弹性绝缘材料。
在本实施例中，间隔层206包括相互隔开的多个间隔部26，该间隔部26均有弹性绝缘材料制成，优选地，弹性绝缘材料可以是泡棉、硅胶或者橡胶，由于间隔层206填充的是弹性绝缘材料，因此力感应导电层204和固定金属层205之间仍然能够形成电容，在图4中，当手指按压201时，由于弹性绝缘材料的弹性特性，力感应导电层204仍然能够产生形变，根据按压前后的电容变化，进而能够推算出压力值以及按压的位置坐标，从而能够实现压力触控的功能，并且当触控面板2发生跌落碰撞时，间隔层206中填充的弹性绝缘材料能够起到有效的缓冲作用，从而能够有效地防止固定金属层205的形变，进而能够防止力感应导电层204和固定金属层205之间的距离发生变化，因此能够防止触控面板2的失效。此外，由于间隔层206部分填充弹性绝缘材料，因此能够节省成本。
进一步地，力感应导电层204包括基底(未示出)和导电图案(未示出)，基底为FPC(Flexible Printed Circuit，柔性电路板)板或者PET(Polyethylene-terephthalate，聚对苯二甲酸乙二醇酯)板，而导电图案由金属铜或者银制成，导电图案通过喷溅的方式形成，优选地，力感应导电层204的厚度为30nm至100nm。因此，力感应导电层204的厚度较小，对触控面板2的厚度影响较小。
实施例三
参照图5和图6，示出根据本发明的第三实施例的触控面板3，该触控面板3为内嵌式触控面板，触控面板3包括盖板301、液晶模组302、背光模组303、力感应导电层304、固定金属层305和间隔层306，其中，盖板301设置在液晶模组302的背离背光模组303的一侧，液晶模组302和背光模组303依次层叠在间隔层306上，而力感应导电层304形成在液晶模组302中，固定金属层305位于间隔层306的背离背光模组303的一侧，固定金属层305例如为触控面板3的金属中框，力感应导电层304和固定金属层305之间形成电容，间隔层306填充有弹性绝缘材料。
在本实施例中，间隔层306由弹性绝缘材料完全填满，优选地，弹性绝缘材料可以是泡棉、硅胶或者橡胶，由于间隔层306填充的是弹性绝缘材料，因此力感应导电层304和固定金属层305之间仍然能够形成电容，在图6中，当手指按压盖板301时，由于弹性绝缘材料的弹性特性，力感应导电层304仍然能够产生形变，根据按压前后的电容变化，进而能够推算出压力值以及按压的位置坐标，从而能够实现压力触控的功能，并且当触控面板3发生跌落碰撞时，间隔层306中填充的弹性绝缘材料能够起到有效的缓冲作用，从而能够有效地防止固定金属层305的形变，进而能够防止力感应导电层304和固定金属层305之间的距离发生变化，因此能够防止触控面板3的失效。
进一步地，力感应导电层304包括基底(未示出)和导电图案(未示出)，基底为FPC(Flexible Printed Circuit，柔性电路板)板或者PET(Polyethylene-terephthalate，聚对苯二甲酸乙二醇酯)板，而导电图案由金属铜或者银制成，导电图案通过喷溅的方式形成，优选地，力感应导电层304的厚度为30nm至100nm。因此，力感应导电层304的厚度较小，对触控面板3的厚度影响较小。
实施例四
参照图7和图8，示出根据本发明的第三实施例的触控面板4，该触控面板4为内嵌式触控面板，触控面板4包括盖板401、液晶模组302、背光模组303、力感应导电层404、固定金属层305和间隔层406，其中，盖板401设置 在液晶模组402的背离背光模组403的一侧，液晶模组402和背光模组403依次层叠在间隔层406上，而力感应导电层404形成在液晶模组402中，固定金属层405位于间隔层406的背离背光模组403的一侧，固定金属层405例如为触控面板4的金属中框，力感应导电层404和固定金属层405之间形成电容，间隔层306填充有弹性绝缘材料。
在本实施例中，间隔层406包括相互隔开的多个间隔部46，该间隔部46均有弹性绝缘材料制成，优选地，弹性绝缘材料可以是泡棉、硅胶或者橡胶，由于间隔层406填充的是弹性绝缘材料，因此力感应导电层404和固定金属层405之间仍然能够形成电容，在图8中，当手指按压盖板401时，由于弹性绝缘材料的弹性特性，力感应导电层404仍然能够产生形变，根据按压前后的电容变化，进而能够推算出压力值以及按压的位置坐标，从而能够实现压力触控的功能，并且当触控面板4发生跌落碰撞时，间隔层406中填充的弹性绝缘材料能够起到有效的缓冲作用，从而能够有效地防止固定金属层405的形变，进而能够防止力感应导电层404和固定金属层405之间的距离发生变化，因此能够防止触控面板4的失效。此外，由于间隔层406部分填充弹性绝缘材料，因此能够节省成本。
进一步地，力感应导电层404包括基底(未示出)和导电图案(未示出)，基底为FPC(Flexible Printed Circuit，柔性电路板)板或者PET(Polyethylene-terephthalate，聚对苯二甲酸乙二醇酯)板，而导电图案由金属铜或者银制成，导电图案通过喷溅的方式形成，优选地，力感应导电层404的厚度为30nm至100nm。因此，力感应导电层404的厚度较小，对触控面板4的厚度影响较小。
