Description

裸眼三维触控显示装置的透镜层及其电极结构 技术领域
本发明是有关于一种裸眼三维液晶显示技术领域，特别是有关于一种裸眼三维触控显示装置的透镜层及其电极结构。
背景技术
目前，随着液晶显示(LCD)技术的不断发展，三维显示技术已经备受关注，三维显示技术可以使得画面变得立体逼真，其最基本的原理是利用左右人眼分别接收不同画面，然后经过大脑对图像信息进行叠加重生，构成立体方向效果的影像。
为了实现三维显示，现有技术是在LCD显示屏前方增加一层裸眼三维开关屏，裸眼三维开关屏按照其实现三维显示的切换原理例如有柱透镜式(lenticular lens type)和光屏障式(barrier type)等，上述两者都可利用开关液晶屏(盒)来实现三维显示的切换动作，例如柱透镜式开关液晶屏一般是由上基板、下基板、以及在两个基板之间的液晶层组成，上基板和下基板分别具有板状电极和条状电极。
当条状电极与板状电极之间存在电位差而产生电场时，与条状电极对应的液晶分子发生旋转，其他液晶分子保持原来形状，不发生旋转，因而当LCD显示屏射出的光线经过开关液晶屏时，将造成类似透镜汇聚光线的效果，而形成左右两眼的视差感受，进而实现了三维显示模式。由于柱透镜式开关液晶屏主要是靠电场弯曲使液晶对光形成汇聚效果，所以无需贴附偏光片。
然而，随着触控屏幕技术的发展，出现了将触摸屏和三维显示相结合的裸眼三维触摸显示装置，其结构是在三维开关液晶屏的前方再额外增加一层触控基板，这种结构及其生产工艺相对复杂，会增加显示屏整体的制作成本，同时由于需要额外增加一层触控基板会增加裸眼三维触控显示装置的整体厚度。

请参照图2及图3所示，所述接触电极6包含多个块状接触部61及数个共极走线62，所述块状接触部61呈矩形且尺寸相同，在本实施例中，所述块状接触部61的尺寸以手指面积尺寸为准而相应，大约3至4平方毫米(mm2)。所述块状接触部61分别电性连接至一触控电路(未绘示)。所述块状接触部61在所述下基板3的一顶面31上排列形成多个列601(见图3所示)，两相邻列601之间具有一下基板间距30，且所述下基板间距30与相应的一个所述条状电极5相面对。在本实施例中，每一所述条状电极5的一延伸方向与所述多个列601的一排列方向平行。所述共极走线62分别电性连接所述块状接触部61，且形成在相应的下基板间距30中，其 中所述共极走线62的宽度为4微米(um)，以减少触控盲区或者干扰三维镜片(lens)液晶的倾倒
请参照图2及图4所示，两相邻条状电极5之间具有一上基板间距20，所述上基板间距20与相应的所述块状接触部61的列601相面对。每一所述条状电极5分别包含一电极走线51，所述条状电极5的电极走线51形成在所述上基板2的底面21的两侧，且所述电极走线51通过导电金球(gold bumps)电性连接所述下基板3导电线路，进而与所述共极走线62在所述下基板3的一侧被打线(bonding)。在本实施例中，所述条状电极5及接触电极6为透明导电膜。
依据上述的结构，如图5所示，为所述条状电极5及所述块状接触部61在所述下基板3上的自电容等效电容变化图。当手指不触摸时，如图6所示，电容Cf未通过手指接触而接地，因此仅形成电容Cg。当手指触摸时，如图7所示，电容Cf通过手指接触而接地，因此形成电容Cf及电容Cg并联。因此，由所述上基板2、下基板3、液晶层4、多个条状电极5、接触电极6共同组成的透镜层成为一个兼具裸眼三维功能及触控功能的开关液晶盒，当所述LCD模块7的背光模块产生的背光穿过所述LCD模块7的液晶显示模块生成了二维影像，二维影像接着会通过所述透镜层向前方射出，因而成为三维影像被用户观看。
如上所述，通过形成多个块状接触部61，可对应不同自电容感应电极，进而实现触控功能。同时，当裸眼三维显示时，所述块状接触部61会通过所述共极走线62而被供电，由于每条所述共极走线62之间的空隙很小，所形成的电场影响液晶倾倒的效果不明显，因而对裸眼三维效果影响很小。当不裸眼三维显示时，所述下基板3的共极走线62通过打线(bonding)拉到外围的触控芯片，可以实现触控功能。同时，使外挂的透镜层(开关液晶盒)直接具备触控功能，因而减少额外的触控层制作，并减少整个裸眼三维触控显示装置100的厚度，及改善穿透率。
本发明已由上述相关实施例加以描述，然而上述实施例仅为实施本发明的范例。必需指出的是，已公开的实施例并未限制本发明的范围。相反地，包含于权利要求书的精神及范围的修改及均等设置均包括于本发明的范围内。
