具体实施方式
有关本发明的前述及其他技术内容、特点与功效，在以下配合参考图式的一优选实施例的详细说明中，将可清楚的呈现。以下实施例中所提到的方向用语，例如：上、下、左、右、前或后等，仅是参考附图的方向。因此，使用的方向用语是用来说明并非用来限制本发明。下面结合附图对本发明作进一步详细的说明：
如图1所示，为本发明的显示组件1工作时示意图。如图1所示，在本实施例中，显示组件1为车辆的前挡风玻璃，投影装置2将车辆行驶信息以一定入射角投射到显示组件1上，部分光反射到观察者3眼中，根据本发明的显示组件，投影装置2以55°～75°入射角θ入射时，显示组件1的反射率在5％～40％之间，当投影装置2的入射角θ在60°～70°之间时，显示组件1的反射率在20％～35％之间；如此，显示组件1可使车辆行驶信息清楚的反射到观察者3眼中，反射率过低，反射光太弱，观察者看不清车辆行驶信息，又不会反射率过大，使投影装置2的反射光过亮而影响观察者正常视线。
如图2所示，为本发明一实施例的显示组件1的结构示意图。显示组件1包括玻璃10/20，显示薄膜，和粘附层30；显示薄膜包括基材40和薄膜叠层100。 基材40可为PET或PVB，粘附层30可为PVB，其中基材40与薄膜叠层100接触的表面为平滑表面。图7为粘附层30的一种实施方式示意图，粘附层30表面为粗糙表面，且其收缩率MD/TD>4；图8为基材40的一种实施方式示意图，当基材40为PET时，基材40与玻璃10之间还包括黏附层，粘附层可为PVB(未在图中展示)；当基材40为PVB时，其与薄膜叠层100接触的表面为平滑表面，且表面粗糙度Ra<8nm，且基材40的收缩率MD/TD<2；基材40与玻璃10直接接触。投射装置2的投射光的入光侧为薄膜叠层100远离基材40的一侧，从图2中来看，入光侧为玻璃20所在一侧。
如图3所示，为本发明一实施例中显示薄膜的结构示意图。显示薄膜包括基材40和薄膜叠层100，本实施例中，薄膜叠层100包括第一高折射率层110，透反射镀层130，及第二高折射率层150；第一高折射率层110、透反射镀层130、及第二高折射率层150均可为物理气相沉积层。第一高折射率层110与第二高折射率层150的折射率范围为1.8～2.4，厚度范围为2nm～200nm，材料选自金属的或非金属的氧化物、氮化物、硫化物、氟化物、碳化物中的一种或多种，具体可为TiO 2、SnO 2、ZnO、Nb 2O 5、Ta 2O 5、Si 3N 4、ZnS、Al 2O 3、MgF，MgS、SiC中的一种或多种，另外，第一高折射率层110与第二高折射率层150的材料还包括掺杂材料，掺杂材料包含Al、Ga、Zr、B、Y、Mo、Sn等一种或多种材料，掺杂材料在物理气相沉积过程中形成高射率层时可与反应气体反应生成AZO、GZO、YZO，此处仅为举例，可根据掺杂材料与反应气体的不同而有其他产物。
透反射镀层130为金属与金属氧化物或金属氮化物共存的层，厚度为5-40nm；具体来说，透反射镀层为至少一种金属与该金属氧化物的层，或至少一种金属与该金属氮化物的层，或至少一种金属与该金属氮化物和该金属氧化物的层。在形成透反射镀层时，使用金属靶材进行物理气相沉积，反应腔室内 通入少量的氧气或氮气或氧气和氮气的混合气体，由于通入的气体的量很少，不足以全部氧化或氮化金属材料，所以形成的镀层是金属与金属氧化物和或金属氮化物共存的层。其中所用的金属靶材可为Ag、Cu、Al、Mo、Ag合金、Cu合金、Al合金、Mo合金靶材，Ag合金靶材中Ag的质量比大于50％，其他成分为Zn、Cu、In、Pt、Pd、Au、Nb、Nd、B、Bi、Ni中的一种或多种；Cu合金靶材中Cu的质量比大于50％，其他成分为Zn、Ag、In、Pt、Pd、Au、Nb、Nd、B、Bi、Ni中的一种或多种；Al合金靶材中Al的质量比大于80％，其他成分为Zn、Cu、In、Pt、Pd、Au、Nb、Nd、B、Bi、Ni中的一种或多种；Mo合金靶材中Mo的质量比大于80％，其他成分为Zn、Cu、In、Pt、Pd、Au、Nb、Nd、B、Bi、Ni中的一种或多种。
如图4所示，为本发明另一实施例中显示薄膜的结构示意图。图中所示与图3相同标号的为相同结构，此处不再赘述。与图3不同之处在于，在第一高折射率层110与透反射镀膜130之间还包括耐候层120，耐候层120厚度为2nm-200nm，耐候层120的材料为非金属氧化物，非金属氮化物，金属硫化物、金属氮化物，或金属氧化物中的一种或多种，具体可为TiN、ZnO、TiO 2、SnO 2、SiO 2、Si 3N 4、ZnS、Al 2O 3、MoO 2中的一种；耐候层120还包括掺杂材料，具体可为Al、Ga、Zr、B、Y、Mo、Sn中的一种或多种材料的氧化物和或氮化物。
如图5所示，为本发明另一实施例中显示薄膜的结构示意图。图中所示与图3相同标号的为相同结构，此处不再赘述。与图3不同之处在于，在透反射镀层130与第二高折射率层150之间还包括抗氧化层140，抗氧化层140的厚度为0.5nm-10nm，抗氧化层140的材料包括金属，合金，金属氧化物，金属氮化物，非金属氧化物，非金属氮化物中的一种，具体来说，抗氧化层140的材料为Ti、Ni、Cr、NiCr、TiN、ZnO、TiO 2、SnO 2、SiO 2、Nb 2O 5、Ta 2O 5、Si 3N 4中 的一种或多种，当抗氧化层140为金属层或合金材料层时，其厚度为0.5～3nm，采用原子沉积工艺或物理气相沉积工艺，当抗氧化层140材料为金属或非金属的氧化物或氮化物时，其厚度为1～10nm，采用原子沉积工艺或物理气相沉积工艺。
