其中，本申请红外光的波长为850纳米-1000纳米，以使得红外传感组件30发射的红外光具有良好的穿透能力而穿过显示面板10等到达驾驶员等目标成像物的同时，保证红外光在驾驶员等目标成像物上具有良好的反射率，红外光经过反射后为红外传感组件30接收，有利于提高红外传感组件30的成像质量。例如，预设波长可以为860纳米、900纳米、920纳米、940纳米、960纳米或者1000纳米。
需要说明的是，基于需要在亮度较暗环境下拍照的需求，本申请采用红外光进行拍摄，然而红外光的波长越长，则红外光的穿透率越高，反射率越低，穿透率低会导致传播的距离短，反射率低会导致红外光的损失量大进而不利于接收红外光，基于车载应用场景中车载显示装置100的红外传感组件30与驾驶员等目标成像物之间的距离等因素，本实施例特定选择红外光以平衡穿透率和反射率进而保证车载应用场景的成像需求。
在本实施例中，显示面板10为液晶显示面板。显示面板10的显示区10b设置有多个像素，以使显示区10b实现显示。每个像素包括红色子像素、绿色子像素以及蓝色子像素，红色子像素、绿色子像素以及蓝色子像素中的任意一者包括像素电极、公共电极、液晶以及对应的色阻。每个像素的形状为正方形，每个子像素为矩形。像素的长度和宽度为200微米-400微米。显示面板10的非显示透光区10a不 用于显示而用于穿透红外光。非显示透光区10a的形状为圆形，非显示透光区10a的形状也可以为其他形状。
其中，显示面板10的非显示透光区10a对红外光的透过率大于显示面板10的显示区10b对红外光的透过率，提高红外光穿过显示面板10的非显示透光区10a的透过率，结合红外光在亮度较暗环境下具有良好的穿透性，进而改善车载显示装置100在亮度较暗环境下的成像质量。
在本实施例中，显示面板10的非显示透光区10a对红外光的透过率大于或等于50％，以保证有足够量的红外光穿过显示面板10，有利于改善成像质量。显示面板10的非显示透光区10a对红外光的透过率越大，则红外传感组件30成像质量越好。例如，显示面板10的非显示透光区10a对红外光的透过率为55％、60％、65％、70％、80％、85％、90％以及95％。
具体地，显示面板10的非显示透光区10a对红外光的透过率大于或等于70％，以保证红外传感组件30能进行清晰地成像。
在本实施例中，如图2所示，显示区10b包括主显示区10b1和过渡显示区10b2，过渡显示区10b2位于主显示区10b1和非显示透光区10a之间。车载显示装置100显示时，过渡显示区10b2用于实现主显示区10b1与非显示透光区10a之间的亮度平滑过渡，避免主显示区10b1与非显示透光区10a之间出现亮边，进而避免非显示透光区10a容易被观察到；车载显示装置100处于息屏状态时，过渡显示区10b2用于使得主显示区10b1与非显示透光区10a之间的反射率 相互匹配，进而避免显示透光区容易被观察到。其中，主显示区10b1的面积大于过渡显示区10b2的面积。过渡显示区10b2的形状为圆环形，可以理解的是，过渡显示区10b2的形状也可以其他形状。
在本实施例中，显示面板10的非显示透光区10a对红外光的透过率大于显示面板10的主显示区10b1对红外光的透过率，显示面板10的过渡显示区10b2的至少部分对红外光的透过率小于显示面板10的主显示区10b1对红外光的透过率，且显示面板10的过渡显示区10b2的至少部分对红外光的透过率在主显示区10b1指向过渡显示区10b2的方向上递减，使得车载显示装置显示时背光穿过过渡显示区10b2后的亮度在主显示区10b1指向非显示透光区10a的方向递减，显示亮度从主显示区10b1的较高亮度，经过过渡显示区10b2的亮度递减，至非显示透光区10a的较低亮度，使得主显示区10b1与非显示透光区10a之间的亮度变化实现平滑过渡，进而避免车载显示装置在显示时显示透光区10a容易被观察到。
具体地，显示面板10的主显示区10b1对红外光的透过率小于50％，以使得显示面板10的主显示区10b1有足够的空间布设晶体管以及金属走线等不透光结构，保证显示面板10具有高分辨率。例如，显示面板10的主显示区10b1对红外光的透过率为10％、15％、20％、25％、30％、35％、40％以及45％等。显示面板10的过渡显示区10b2对红外光的透过率小于50％。例如，显示面板10的过渡显示区10b2对红外光的透过率为10％、15％、20％、25％、30％、35％、40％以及45％等。
需要说明的是，在本申请中，透过率是指光穿过显示面板之后的亮度与光穿过显示面板之前初始亮度的比值。
在本实施例中，在主显示区10b1指向非显示透光区10a的方向上过渡显示区10b2的尺寸大于或等于5个像素对应的尺寸，以保证过渡显示区10b2在主显示区10b1指向非显示透光区10a的方向上的尺寸足够大进而保证有足够的像素实现亮度的平滑过渡；且在主显示区10b1指向所述非显示透光区10a的方向上过渡显示区10b2的尺寸小于或等于15个像素对应的尺寸，以避免过渡显示区10b2在主显示区10b1指向非显示透光区10a的方向上的尺寸太大而导致非显示透光区10a容易为人眼识别出来。例如，在主显示区10b1指向非显示透光区10a的方向上过渡显示区10b2的尺寸等于6个像素对应的尺寸、7个像素对应的尺寸、8个像素对应的尺寸、10个像素对应的尺寸、12个像素对应的尺寸或者15个像素对应的尺寸。
具体地，非显示透光区10a的形状为圆形时，在主显示区10b1指向非显示透光区10a的方向上且沿非显示透光区10a的径向，过渡显示区10b2的尺寸等于10个像素对应的尺寸。例如，一个像素的尺寸为150微米，则10个像素的尺寸为1.5毫米。
需要说明的是，本申请通过对显示面板的非显示透光区10a、过渡显示区10b2以及主显示区10b1的膜层进行差异化设计，以实现非显示透光区10a对红外光的透过率大于主显示区10b1对红外光的透过率，主显示区10b1对红外光的透过率大于过渡显示区10b2对红外光的透过率，且过渡显示区10b2对红外光的透过率在主显示区10b1 指向非显示透光区10a的方向上递减。
在本实施例中，显示面板10包括阵列基板101、彩膜基板102以及液晶层。阵列基板101与彩膜基板102相对设置，液晶层设置于阵列基板101与彩膜基板102之间。
其中，如图3所示，阵列基板101具有对应非显示透光区10a的第一区域101a以及对应显示区10b的第三区域101b，第三区域101b位于第一区域101a的外围，第三区域101b包括对应过渡显示区10b2的第一子区域101b1和对应主显示区10b1的第二子区域101b2。彩膜基板102具有对应非显示透光区10a的第二区域102a以及对应显示区10b的第四区域102b，第四区域102b包括对应过渡显示区10b2的第三子区域102b1和对应主显示区10b1的第四子区域102b2，第一区域101a与第二区域102a之间的重合区域为非显示透光区10a。
其中，第一区域101a的面积与第二区域102a的面积相异，以保证阵列基板101与彩膜基板102对盒之后第一区域101a与第二区域102a的重叠区域的面积大于或等于预设的非显示透光区10a的面积。
具体地，当彩膜基板102位于显示面板10的出光侧时，第二区域102a的面积小于第一区域101a的面积，以使得靠近出光侧的非显示区更小，人眼更难识别车载显示装置的非显示区。可以理解的是，当阵列基板101位于显示面板10的出光侧时，第一区域101a的面积小于第二区域102a的面积。
在本实施例中，如图2所示，阵列基板101包括依次叠置的第一基板1011、缓冲层1012、栅极金属层(未示意出)、栅极绝缘层1013、 源漏极金属层(未示意出)、层间绝缘层1014、平坦化层1015、公共电极层1016、钝化层1017、像素电极层1018以及盲孔101c。其中，缓冲层1012为氧化硅层。栅极绝缘层1013为氧化硅层。层间绝缘层1014包括氧化硅层和氮化硅层。平坦化层1015为有机层。公共电极层1016为氧化铟锡层。钝化层1017为氮化硅层。像素电极层1018的制备材料为氧化铟锡。
在本实施例中，如图2所示，像素电极层1018包括多个具有狭缝的像素电极1018a以及第一通孔1018b，多个具有狭缝的像素电极1018a设置于阵列基板101的第三区域101b，第一通孔1018b设置于阵列基板101的第一区域101a且贯穿像素电极层1018，以避免具有狭缝的像素电极1018a对需要穿过非显示透光区10a的预设波长红外光进行衍射，影响预设波长红外光的传输。另外，红外光经过像素电极1018a的穿过率较低，去除非显示透光区10a的像素电极1018a有利于提高显示面板的非显示透光区10a对红外光的透过率。
在本实施例中，盲孔101c设置于第一区域101a且盲孔101c贯穿层间绝缘层1014、公共电极层1016以及钝化层1017，以提高阵列基板101的第一区域101a对红外光的透过率。可以理解是，也可以盲孔101c贯穿层间绝缘层1014、公共电极层1016以及钝化层1017中的一个或者两个膜层，以提高阵列基板101的第一区域101a对红外光的透过率，进而提高非显示透光区对红外光的透过率。
由于对阵列基板101的第一区域101a的金属膜层及部分非金属膜层进行去除，导致阵列基板101的第一区域101a的透过率较高， 且反射率较低。而阵列基板101的第三区域101b仍然保留金属膜层和所有非金属膜层，导致阵列基板101的第三区域101b的透过率较低，且反射率较高。
如下表1所示，其为阵列基板的组成膜层对940±10nm的红外光的透过率。
表1
膜层 透过率
缓冲层 100％
栅极绝缘层 90％-100％
层间绝缘层 65％-75％
平坦化层 100％
公共电极层 50％-60％
钝化层 65％-75％
像素电极层 65％-75％
由表1可知，阵列基板上的层间绝缘层、公共电极层、钝化层以及像素电极层对波长为940±10nm的红外光的透过率较低，将阵列基板的第一区域101a的这些膜层去除，有利于提高红外光在非显示透光区的透过率。
在本实施例中，彩膜基板102包括第二基板1021、彩色膜层1022、黑色矩阵层1023以及支撑柱1024。彩色膜层1022、黑色矩阵层1023以及支撑柱1024均设置于第二基板1021上。
在本实施例中，黑色矩阵层1023包括黑色矩阵块1025和分布于 黑色矩阵块1025之间的多个开口。黑色矩阵块1025一方面具有吸光的性质，另一方面也具有反射光的性质，黑色矩阵块1025对光的吸光率大于其反射率，即黑色矩阵块1025的主要特性为吸光。开口使得光更容易穿过彩膜基板102。其中，黑色矩阵块1025的制备材料可以为金属材料，黑色矩阵块1025的制备材料也可以为有机树脂和黑色颜料。
其中，如图4所示，设置于主显示区10b1的黑色矩阵块1025在主显示区10b1的面积占比大于设置于非显示透光区10a的黑色矩阵块1025在非显示透光区10a的面积占比，进一步地以使得主显示区10b1对红外光的透过率小于非显示透光区10a对红外光的透过率。设置于过渡显示区10b2的黑色矩阵块1025在过渡显示区10b2的面积占比大于主显示区10b1的黑色矩阵块1025在主显示区10b1的面积占比，且设置于过渡显示区10b2的黑色矩阵块1025在过渡显示区10b2的单位面积占比沿着主显示区10b1指向非显示透光区10a的方向递增，一方面使得车载显示装置显示时主显示区10b1对背光的透过率大于过渡显示区10b2对背光的透过率，进而车载显示装置显示时主显示区10b1的亮度大于过渡显示区10b2的亮度，且过渡显示区10b2的亮度在主显示区10b1指向非显示透光区10a的方向上递减，由于非显示透光区10a中无背光源，过渡显示区10b2的亮度大于非显示透光区10a的亮度，有利于显示装置显示时亮度的平滑过渡。另一方面，车载显示装置处于息屏状态时，过渡显示区10b2的黑色矩阵块1025的分布密度沿着主显示区10b1指向10b1的方向递增，由 于黑色矩阵块1025的吸光作用，使得环境光穿过过渡显示区10b2的黑色矩阵块1025的通量沿着主显示区10b1指向10b1的方向递减，阵列基板侧的金属对环境光的反射率沿着主显示区10b1指向10b1的方向递减，主显示区10b1由于阵列基板101的金属膜层反射率较高，而非显示透光区10a无金属膜层而反射率较低，过渡显示区10b2的黑色矩阵块1025的设计使得主显示区10b1对环境光的反射率至非显示透光区10a对环境光的反射率实现匹配。
其中，设置于主显示区10b1的黑色矩阵块1025在主显示区10b1的面积占比与设置于非显示透光区10a的黑色矩阵块1025在非显示透光区10a的面积占比的比值大于或等于1.5，以使得主显示区10b1的透光率小于非显示透光区10a的透光率。例如比值为1.5、2、3、8、10或者15。
在本实施例中，黑色矩阵块1025在主显示区10b1的面积占比大于或等于30％，黑色矩阵块1025在非显示透光区10a的面积占比大于或等于0％且小于或等于20％。例如黑色矩阵块1025在主显示区10b1的面积占比为35％、40％、45％、50％、60％或者70％；黑色矩阵块1025在非显示透光区10a的面积占比为0％、2％、5％、8％、10％或者15％。
具体地，黑色矩阵块1025在非显示透光区10a的面积占比大于0％且小于或等于20％，以使得非显示透光区10a保留少量黑色矩阵块1025，提高车载显示装置处于息屏状态时非显示透光区10a对环境光的反射率，进一步地提高车载显示装置处于息屏状态时非显示透 光区10a与主显示区10b1之间的反射率的匹配程度。
在本实施例中，如图4所示，多个开口包括多个第一开口1026、多个第二开口1027以及至少一个第三开口1028，多个第一开口1026设置于主显示区10b1，多个第二开口1027设置于过渡显示区10b2，至少一个第三开口1028设置于非显示透光区10a，第二开口1027的尺寸小于或等于第一开口1026的尺寸，且在主显示区10b1指向非显示透光区10a的方向上至少部分第二开口的尺寸递减，第三开口1028的尺寸大于第一开口的尺寸。
在本实施例中，如图2所示，彩色膜层1022包括第一红色色阻R1、第一蓝色色阻B1、第一绿色色阻G1、第二红色色阻R2以及第二蓝色色阻B2。依次排布的一个第一红色色阻R1、一个第一蓝色色阻B1以及一个第一绿色色阻G1组成一个第一重复单元，多个第一重复单元重复地设置于彩膜基板102的第四区域102b，一个第一红色色阻R1、一个第一蓝色色阻B1以及一个第一绿色色阻G1中任意两者之间设置有黑色矩阵块1025；第二红色色阻R2以及第二蓝色色阻B2叠置地设置于彩膜基板102的第二区域102a，第二红色色阻R2靠近第二基板1021设置且位于第三开口1028内及黑色矩阵块1025上。
如图5所示，其为本申请另一实施例车载显示装置的彩膜基板的示意图。图5所示彩膜基板与图2所示彩膜基板基本相似，不同之处在于，彩色膜层1022包括设置于彩膜基板102的第二区域102a的第二绿色色阻G2和第二蓝色色阻B2的叠层,第二绿色色阻G2靠近第 二基板1021设置且位于第三开口1028内及黑色矩阵块1025上。
如图6所示，其为本申请又一实施例车载显示装置的彩膜基板的示意图。图6所示彩膜基板与图2所示彩膜基板基本相似，不同之处在于，黑色矩阵块1025在彩膜基板102的第二区域102a的面积占比为0％，且彩色膜层1022包括设置于彩膜基板102的第二区域102a的第二重复单元，第二重复单元由依次排布的一个第二红色色阻R2、一个第二蓝色色阻B2以及一个第二绿色色阻G2组成。其中，第二红色色阻R2与第一红色色阻R1相同，第二蓝色色阻B2与第一蓝色色阻B1相同，第二绿色色阻G2与第一绿色色阻G1相同。可以理解的是，第二红色色阻R2的尺寸与第一红色色阻R1的尺寸可以不同，第二蓝色色阻B2的尺寸与第一蓝色色阻B1的尺寸可以不同，第二绿色色阻G2的尺寸与第一绿色色阻G1的尺寸也可以不同。
如表2所示，其为彩膜基板中的各膜层对940±10nm的红外光的透过率。
表2
膜层 透过率
黑色矩阵块 小于10％
红色色阻 大于90％
蓝色色阻 大于90％
绿色色阻 大于90％
由表2可知，黑色矩阵块对波长为940±10nm的红外光的透过率非常低，减少黑色矩阵块有利于提高彩膜基板的第二区域对红外光 的透过率，而保留彩色膜层对红外光的透过率的影响较小。
在本实施例中，支撑柱1024包括第一支撑柱10241和第二支撑柱10242，第一支撑柱10241设置于第四子区域102b2且对应黑色矩阵块1025设置，第二支撑柱10242设置于第三子区域102b1且对应黑色矩阵块1025设置。其中，第一支撑柱10241的高度等于第二支撑柱10242的高度，第一支撑柱10241的分布密度小于第二支撑柱10242的分布密度，以使得显示面板在显示区10b和非显示透光区10a的盒厚具有均一性。可以理解的是，第一支撑柱10241的高度等于第二支撑柱10242的高度时，第一支撑柱10241的分布密度也可以等于第二支撑柱10242的分布密度，此时，通过第一支撑柱10241靠近第二基板1021的底面面积小于第二支撑柱10242的靠近第二基板1021的底面面积，以使得显示面板在显示区10b和非显示透光区10a的盒厚具有均一性。
需要说明的是，彩膜基板102在非显示透光区10a不设置支撑柱或者设置少量的支撑柱，以避免支撑柱对红外光起到衍射作用而影响预设波长红外光的传输。
如表3所示，其为本申请显示面板1至显示面板4对波长为940±10纳米的红外光的透过率，其中3L为缓冲层，GI为栅极绝缘层，ILD为层间绝缘层，BITO为公共电极层，TITO为像素电极层，PLN为平坦化层，缓冲层、栅极绝缘层、层间绝缘层、公共电极层、平坦化层以及像素电极层的位置关系如图2所示；R为红色色阻，G为绿色色阻，B为蓝色色阻，PS为支撑柱，BM面积占比为黑色矩阵块的 面积占比，红色色阻、蓝色色阻、支撑柱以及黑色矩阵块如图2所示；+表示膜层保留，-表示膜层挖除。
表3
Figure PCTCN2021134621-appb-000001
Figure PCTCN2021134621-appb-000002
由表3可知，本实施例显示面板在非显示透光区对940±10纳米的红外光的透过率可以高达80％以上。在非显示透光区，BM面积占比越大，则显示面板对940±10纳米的红外光的透过率越低。在非显示透光区，去除对940±10纳米的红外光透过率较低的膜层，更有利于提高对940±10纳米的红外光的透过率。
在本实施例中，显示面板10的非显示透光区10a的面积大于或等于红外传感组件30的入光面30a面积，以提高红外传感组件30发出的红外光经过显示面板10的穿透率。
具体地，显示面板10的非显示透光区10a的面积大于红外传感组件30的入光面面积，以保证红外传感组件30在一定组装精度范围内，穿过显示面板10的穿透率较高。例如，显示面板10的非显示透光区10a和红外传感组件30的入光面均为圆形时，显示面板10的非显示透光区10a的直径为5.8毫米，红外传感组件30的入光面的直 径为5.3毫米。
在本实施例中，背光模组20为侧入式背光模组20。背光模组20用于为显示面板10的显示区提供背光。背光模组20包括底板201、导光板202以及光学膜片203，导光板202设置于底板201上，光学膜片203设置于导光板202上，第二通孔20a贯穿导光板202以及光学膜片203，以避免导光板202以及光学膜片203对红外光的传输造成干扰而影响成像。其中，光学膜片包括扩散膜、棱镜膜以及增亮膜等。
另外，背光模组20还包括环型挡墙204，环型挡墙204设置于底板201上且对应非显示透光区10a设置，环型挡墙204围绕红外传感组件30的出光面30a，以避免红外传感组件30发出的红外光入射至显示区10b。而且，环形挡墙204与显示面板10之间设置有环形吸光垫205，环形吸光垫205避免红外光通过显示面板10与背光模组20之间的间隙进入至显示区10b。
需要说明的是，本实施例显示面板10的非显示透光区10a采用盲孔的设计，搭配背光模组20对应显示面板10的非显示透光区10a的通孔设计，以保证对红外光的透过率，进而保证红外传感组件30的成像质量。
在本实施例中，显示面板10的非显示透光区10a的面积小于第二通孔20a的横截面积，以使得在一定安装公差的情况下红外传感组件30能容置于第二通孔20a中。例如，显示面板10的非显示透光区10a和第二通孔20a的横截面均为圆形时，显示面板10的非显示透 光区10a的直径为5.8毫米，第二通孔20a的横截面的直径为7.5毫米。
在本实施例中，车载显示装置100还包括防眩层50，防眩层50用于改善背光模组20的光学膜片使用过程中存在的摩尔纹现象。防眩层50设置于背光模组20与显示面板10之间，防眩层50对应非显示透光区10a设置有第三通孔50a，以避免防眩层50对红外光的传输造成干扰。
具体地，如图7所示，防眩层50设置于第一偏光片401靠近显示面板10的表面上，第三通孔50a中设置有透光保护层60，以保护第一偏光片401对应第三通孔50a对应的部分的同时，保证红外光的透过率。其中，透光保护层60可以只是设置于第三通孔50a中，透光保护层60也可以整面的设置于防眩层50远离第一偏光片401的表面和第二通孔20a中。防眩层50为涂布于第一偏光片401上的二氧化硅颗粒层，透光保护层60为氮化硅层等硬质涂层。
如图8所示，其为第一偏光片401靠近显示面板10的表面上可以设置整面的透光保护层60，以保护第一偏光片401靠近显示面板10的表面。
以上实施例的说明只是用于帮助理解本申请的技术方案及其核心思想；本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例的技术方案的范围。
