针对现有透明显示屏存在画面显示效果不佳的问题，本申请提供一种透明显示装置和终端可以解决这个问题。
本申请提供一种透明显示装置，包括透明显示面板、调光膜以及控制单元，控制单元用于控制调光膜处于第一状态或第二状态；当调光膜处于第一状态时，调光膜的透光率低于阈值，阻挡来自背离透明显示面板出光方向上的物体的光线；当调光膜处于第二状态时，调光膜的透光率高于阈值，透过来自背离透明显示面板出光方向上的物体的光线。
调光膜和透明显示面板的相对位置有多种不同的设置方式，在图1、图2中，调光膜设置在透明显示面板内部，在图6至图9中，调光膜设置在透明显示面板内部，根据调光膜与透明显示面板之间位置的不同，本申请的透明显示装置具有多种不同的结构。
在本申请中，透明显示面板为主动发光显示面板，例如透明OLED显示面板，透明Micro_LED显示面板，透明LED显示面板等。
如图1所示，为本申请提供的透明显示装置的第一种结构示意图。透明显示装置包括包括透明显示面板10、调光膜20以及控制单元（图未示出），控制单元用于控制调光膜20处于第一状态或第二状态；当调光膜20处于第一状态时，调光膜20的透光率低于阈值，阻挡来自背离透明显示面板10出光方向上的物体的光线；当调光膜20处于第二状态时，调光膜20的透光率高于阈值，透过来自背离透明显示面板10出光方向上的物体的光线。
在本实施例中，调光膜20设置在透明显示面板10外部。

在另一种实施例中，当透明显示面板10与调光膜20一体设置时，调光膜20通过直接在透明显示面板10上直接制备得到。即以透明显示面板10为衬底，在透明显示面板10上形成第一透明基板24，在第一透明基板24上形成第一透明电极21；同时，在第二透明基板25上形成第二透明电极22；将第一透明电极21与第二透明电极22对盒，并在第一透明电极21和第二透明电极22之间注入聚合物微晶，并辐射紫外线以形成聚合物分散微晶层。透明显示面板10与调光膜20一体化设置，透明显示面板10与调光膜20的适配性更好。

如图2所示，为本申请实施例提供的透明显示装置的第二种结构示意图。透明显示装置包括包括透明显示面板10、调光膜20以及控制单元（图未示出）。
在本实施例中，调光膜20设置在透明显示面板10外部。
调光膜20包括相对设置的第一透明电极21、第二透明电极22、以及位于第一透明电极21和第二透明电极22之间的聚合物微晶23。调光膜20还包括透明基板26，透明基板26设置在第二透明电极22远离第一透明电极21的一侧。
在本实施例中，透明显示面板10与调光膜20为一体设置。将透明显示面板10作为第一透明电极21的衬底基板，在透明显示面板10上直接形成第一透明电极21；同时，在透明基板26上形成第二透明电极22；将第一透明电极21与第二透明电极22对盒，并在第一透明电极21和第二透明电极22之间注入聚合物微晶，并辐射紫外线以形成聚合物分散微晶层。
在本实施例中，以透明显示面板10作为衬底基板，减少了一层透明基板的设置，减薄了整体透明显示装置的厚度，同时，直接在透明显示面板10上直接制备第一透明电极21，简化了制作流程。
在一种实施例中，紫外线以10mW/cm2至50mW/cm2的强度来辐射。
在本申请提供的实施例中，透明基板26可以是透明玻璃基板或塑料薄膜等，例如：三乙酰纤维素(TAC)、二乙酰纤维素(DAC)等的纤维素树脂膜，降冰片烯等的环烯烃聚合物(COP)膜，环烯烃共聚物 (COC)、聚(甲基丙烯酸甲酯)(PMMA)等的丙烯酸树脂膜，聚碳酸酯(PC)、聚乙烯(PE)、聚丙 烯(PP)等的聚烯烃膜，聚乙烯醇(PVA)、聚醚砜(PES)、聚醚醚酮(PEEK)、聚醚酰亚胺 (PEI)、聚萘二甲酸乙二醇酯(PEN)、聚对苯二甲酸乙二醇酯(PET)等的聚酯膜，聚酰亚胺(PI)膜，聚砜(PSF)膜，氟化物树脂膜等。第一透明基板21和第二透明基板25可以采用同种材料，也可以采用不同的材料。
在本申请提供的实施例中，第一透明电极21和第二透明电极22为透明导电薄膜，例如：氧化银(AgO、Ag2O或Ag2O3)薄膜、氧化铝(Al2O3)薄膜，氧化钨(WO2、WO3或W2O3)薄膜、氧化镁(MgO)薄膜、氧化钼(MoO3)薄膜、氧化锌(ZnO)薄膜、氧化锡(SnO2)薄膜、氧化铟(In2O3)薄膜、氧化铬(CrO3或Cr2O3)薄膜、氧化锑(Sb2O3或Sb2O5)薄膜、氧化钛(TiO2)薄膜、氧化镍(NiO)薄膜、氧化铜(CuO或Cu2O)薄膜、氧化钒(V2O3或V2O5)薄膜、氧化钴(CoO)薄膜、氧化铁(Fe2O3或Fe3O4)薄膜、氧化铌(Nb2O5)薄膜、氧化铟锡(ITO)薄膜、氧化铟镓(IZO)薄膜、掺杂铝的氧化锌(ZAO)薄膜、氧化锡铝(TAO)薄膜或氧化锑锡(ATO)薄膜等。
控制单元用于控制调光膜20处于第一状态或第二状态；当调光膜20处于第一状态时，调光膜20的透光率低于阈值，阻挡来自背离透明显示面板10出光方向上的物体的光线；当调光膜20处于第二状态时，调光膜20的透光率高于阈值，透过来自背离透明显示面板10出光方向上的物体的光线。
在调光膜20中，第一透明电极21和第二透明电极22之间设置有聚合物微晶23，聚合物微晶23由液晶和有机聚合物混合形成，其中，有机聚合物聚合物为聚丙烯酸酯，环氧树脂、丙烯酸和聚酰亚胺中的至少一种。
聚合物微晶23是将小分子液晶分散到聚合物中，在一定条件下发生聚合反应，形成微米级的液晶微滴均匀地分散在高分子网络中，形成的一种具有特殊光电性能的复合材料，其中微滴尺寸一般小于10μm。
聚合物微晶23在施加电压和未施加电压情况下，具有不同的状态。
在未施加电压时，液晶微滴的寻常光折射率与聚合物的折射率失配，不同微滴内液晶的指向矢的指向是随机的，因而聚合物微晶23呈现出对光线散射作用，呈现乳白色的不透明状态，外界光线不能透过；在施加电压时，液晶指向矢受电场作用沿电场方向排列，从而所有液晶微滴中的液晶分子指向矢一致，此时液晶微滴与聚合物折射率匹配，所以聚合物微晶23呈现出透明的特征，外界光线可以透过。
在本实施例中，液晶为负型液晶，负型液晶材料相对正性液晶而言，在电场的作用下有着不同的转动惯量。负型液晶分子因垂直于电场分布因而表现出较低的倾斜角，且比起正性液晶，负型液晶扭曲角分布也较均匀，故表现出较高的穿透率，比正性液晶穿透率高10%～15%。
聚合物为聚丙烯酸酯，环氧树脂、丙烯酸和聚酰亚胺中的至少一种。在本实施例中，聚合物为聚酰亚胺，聚酰亚胺因具有耐高低温、高强度与高模量、低热膨胀系数和介电常数、优异的绝缘性能以及耐辐照性等优异性能而被广泛地应用。
如图3所示，为本申请实施例提供的调光膜在第一状态时的透光示意图。透明显示装置还包括驱动电路40，驱动电路40电连接第一透明电极21和第二透明电极22，用于提供驱动电压。控制单元（图未示出）控制驱动电路40断开时，调光膜20处于第一状态。聚合物微晶23中的液晶微滴对寻常光的折射率，与有机聚合物对寻常光的折射率不匹配，因此，光线在穿过聚合物微晶23时，由于受到层内微滴的散射作用，光路发生不一致的改变，导致射出调光膜20的光线呈散乱状态，即调光膜20的透光率小，外观表现为半透明的乳白色散射态。
如图4所示，为本申请实施例提供的调光膜在第二状态时的透光示意图。透明显示装置还包括驱动电路40，驱动电路40电连接第一透明电极21和第二透明电极22，用于提供驱动电压。控制单元（图未示出）控制驱动电路40连接时，调光膜20处于第二状态。此时，在第一透明电极21和第二透明电极22相对的空间内形成电场，由于受到外界电场的驱动，微晶分子发生偏转，指向矢均沿电场方向排列，从而使得液晶和有机聚合物的折射率匹配一致。当光线在穿过聚合物微晶23时，聚合物微晶23内的微滴对光的折射作用一致，光路的变化一致，从而射出调光膜20的光线的光路与射入调光膜20的光线的光路相同，即调光膜20的透光率大，外观表现为透明态。
另外，微晶分子的偏转角度受外界电场的影响，在一定电场范围内，电场强度越强，微晶分子的偏转角度越大，电场强度越小，微晶分子的偏转角度越小。通过控制第一驱动电路50输入电压的大小，调节第一透明电极21和第二透明电极22间电场的强弱，从而可以调节微晶分子的偏转角度，进而调节调光膜20的透光率。
在图1和图2中，调光膜20均设置在显示面板10的外部，调光膜20与显示面板10可以一体设置，也可以独立设置。现结合透明显示面板10与调光膜20的相对位置，对本申请提供的显示装置作进一步详细描述。
在一种实施例中，如图5所示，调光膜20设置于透明显示面板10出光方向的一侧。
当透明显示面板10显示时，控制单元（图未示出）控制第一驱动电路50断开，调光膜20处于第一状态，调光膜20的透光率低于阈值，调光膜20内的聚合物微晶23散乱分布，聚合物微晶23中的液晶微滴和有机聚合物的指向矢不一致，导致位于透明显示面板10背光方向上的物体投射过来的光线在穿过调光膜到达人眼时，受到严重的散射，无法完整成像。调光膜20起到了阻挡背景物体光线干扰的作用。
同时，调光膜20会对透明显示面板10投射过来的光线进行一定程度散射，调光膜20阻挡了透明显示面板10背光方向上物体的光线干扰，同时减弱了透明显示面板10光线的强度，综合显示效果，一定程度上提高了透明显示面板10到达人眼的画面的清晰度。
当透明显示面板10不显示时，控制单元（图未示出）控制第一驱动电路50连通，调光膜20处于第二状态，当外加电压达到阈值电压时，调光膜20内的聚合物微晶23在外加电场的作用下开始发生偏转，调光膜20的透光率高于阈值，当外加电压达到一定的电压时，调光膜20内的聚合物微晶23的偏转达到最大角度，微晶分子的指向矢均沿电场方向排列，从而使得液晶和有机聚合物的折射率匹配一致，调光膜20的透光率达到最大。当位于透明显示面板10背光方向上的物体投射过来的光线在穿过调光膜到达人眼时，聚合物微晶23内的微滴对光的折射作用一致，光路的变化一致，从而射出调光膜20的光线的光路与射入调光膜20的光线的光路相同，即调光膜20起到了透明玻璃的作用，能够完整透过位于透明显示面板10背光方向上的物体投射过来的光线。
在一种实施例中，如图6所示，调光膜20设置于背离透明显示面板10出光方向的一侧。
当透明显示面板10显示时，控制单元（图未示出）控制第一驱动电路50断开，调光膜20处于第一状态，调光膜10的透光率低于阈值，调光膜20内的聚合物微晶23散乱分布，聚合物微晶23中的液晶微滴和有机聚合物的指向矢不一致，导致位于透明显示面板10背光方向上的物体投射过来的光线在穿过调光膜到达人眼时，受到严重的散射，无法完整成像。调光膜20起到了阻挡背景物体光线干扰的作用。在该实施例中，由于调光膜只会阻挡位于透明显示面板10背光方向上的物体投射过来的光线，因此聚合物微晶23还可以包括二向色性染料，所述二向色性染料按所述液晶材料的0.5wt％至5wt％来添加。位于透明显示面板10背光方向上的物体投射过来的光线在穿过聚合物微晶23时，在被聚合物微晶23散射的同时，进一步被二向色性染料吸收，即调光膜20可根据光被聚合物微晶23散射并二向色性染料吸收来实现光的阻挡作用，避免位于透明显示面板10背光方向上的物体达到人眼，影响透明显示面板10的显示效果。
当透明显示面板10不显示时，控制单元（图未示出）控制第一驱动电路50连通，调光膜20处于第二状态，当外加电压达到阈值电压时，调光膜20内的聚合物微晶23在外加电场的作用下开始发生偏转，调光膜10的透光率高于阈值，当外加电压达到一定的电压时，调光膜20内的聚合物微晶23的偏转达到最大角度，微晶分子的指向矢均沿电场方向排列，从而使得液晶和有机聚合物的折射率匹配一致，调光膜20的透光率达到最大。当位于透明显示面板10背光方向上的物体投射过来的光线在穿过调光膜到达人眼时，聚合物微晶23内的微滴对光的折射作用一致，光路的变化一致，从而射出调光膜20的光线的光路与射入调光膜20的光线的光路相同，即调光膜20起到了透明玻璃的作用，能够完整透过位于透明显示面板10背光方向上的物体投射过来的光线。
由此，不管调光膜20设置在透明显示面板10出光方向的一侧，还是设置于背离透明显示面板10出光方向的一侧，都可以在控制单元的控制下，在第一状态和第二状态之间切换，以阻挡或透过背离所述透明显示面板出光方向上的物体的光线，从而减少来自背离透明显示面板出光方向上的物体的光线对透明显示面板显示效果的影响，缓解了现有透明显示屏存在画面显示效果不佳的问题。
