The light transmitted through the color display pixels 30 is not blocked.
当上述双面显示面板工作时，通过在彩色侧加载电极32和彩色侧透明电极34之间施加一个电压差，激发彩色侧有机功能层33，使彩色侧有机功能层33发光，彩色侧有机功能层33发出的光中，一部分光依次经彩色侧透明电极34和彩膜层35朝向图1的上方射出，另一部分光入射至彩色侧加载电极32中，在彩色侧加载电极32中透射，并在彩色侧反射层31朝向彩色侧有机功能层33的表面发生反射，然后依次经彩色侧加载电极32、彩色侧有机功能层33、彩色侧透明电极34和彩膜层35朝向图1的上方射出，或者，另一部分光在彩色侧加载电极32朝向彩色侧有机功能层33的表面发生反射，然后依次经彩色侧有机功能层33、彩色侧透明电极34和彩膜层35朝向图1的上方射出，有机功能层33发出的光经彩膜层35后，获得所需要的颜色的光，即经彩色显示像素30朝向图1的上方射出的光为彩色光，以使双面显示面板的上方显示彩色画面，双向显示面板的上方实现彩色显示。When the above-mentioned double-sided display panel is working, by applying a voltage difference between the color-side loading electrode 32 and the color-side transparent electrode 34, the color-side organic functional layer 33 is excited, so that the color-side organic functional layer 33 emits light, and the color-side organic function Among the light emitted by the layer 33, a part of the light sequentially passes through the color-side transparent electrode 34 and the color filter layer 35 and is emitted toward the top of FIG.

Color screen, the top of the two-way display panel realizes color display.
通过在黑白侧加载电极73和黑白侧透明电极71之间施加一个电压差，激发黑白侧有机功能层72，使黑白侧有机功能层72发光，黑白侧有机功能层72发出的光中，一部分光经黑白侧透明电极71朝向图1的下方射出，另一部分光入射至黑白侧加载电极73中，透过黑白侧加载电极73，并在黑白侧反射层74朝向黑白侧有机功能层72的表面上发生反射，然后依次经黑白侧加载电极73、黑白侧有机功能层72和黑白侧透明电极71朝向图1的下方射出，或者，另一部分光在黑白侧加载电极73朝向黑白侧有机功能层72的表面发生反射，然后依次经黑白侧有机功能层72和黑白侧透明电极71朝向图1的下方射出，由于经黑白显示像素70射出的光未经过彩膜，因而经黑白显示像素70射出的光为白光，以使双面显示面板的下方显示黑白画面，双向显示面板的下方实现黑白显示。By applying a voltage difference between the black and white side loading electrode 73 and the black and white side transparent electrode 71, the black and white side organic functional layer 72 is excited to make the black and white side organic functional layer 72 emit light, and in the light emitted by the black and white side organic functional layer 72, a part of the light The black and white side transparent electrode 71 emits towards the bottom of FIG. 1 , and another part of the light is incident into the black and white side loading electrode 73, passes through the black and white side loading electrode 73, and is on the surface of the black and white side reflective layer 74 facing the black and white side organic functional layer 72 Reflection occurs, and then sequentially passes through the black and white side loading electrode 73, the black and white side organic functional layer 72 and the black and white side transparent electrode 71 and then emits toward the bottom of FIG. The surface is reflected, and then sequentially emitted through the organic functional layer 72 on the black and white side and the transparent electrode 71 on the black and white side toward the bottom of FIG. white light, so that the bottom of the double-sided display panel displays black and white images, and the bottom of the bidirectional display panel realizes black and white display.
例如，当将上述双面显示面板应用于手机、平板电脑等移动终端时，当需要利用移动终端查看彩色图片、彩色视频等彩色画面时，则可以通过彩色显示像素30的出光面的一侧显示，即通过图1中双面显示面板的上侧显示彩色画面，当需要利用移动终端查看黑白文字、黑白图片、黑白视频等黑白画面时，则可以通过黑白显示像素70的出光面的一侧显示。For example, when the above-mentioned double-sided display panel is applied to mobile terminals such as mobile phones and tablet computers, when it is necessary to use the mobile terminal to view color images such as color pictures and color videos, it can be displayed on one side of the light-emitting surface of the color display pixel 30. , that is, a color picture is displayed on the upper side of the double-sided display panel in FIG. .
由上述可知，本发明实施例提供的双面显示面板包括呈阵列排布的多个像素，每个像素包括彩色显示像素30和黑白显示像素70，彩色显示像素30的彩色侧反射层31与黑白显示像素70的黑白侧反射层74相对设置，因而经彩色显示像素30透出的光的方向与经黑白显示像素70透出的光的方向相反，实现在双面显示面板的两侧均可显示画面；彩色显示像素30包括彩膜层35，也就是说，彩色显示像素30可以实现彩色显示，黑白显示像素70不包括彩膜层，也就是说，黑白显示像素70可以实现黑白显示，黑白画面可以通过上述双面显示面板的黑白显示像素70的出光面的一侧进行显示，由于黑白显示像素70不包括彩膜层，因而可以减少黑白侧有机功能层72发出的光的损失，因而在较小的电量下，便可以在黑白显示像素70的出光面的一侧实现高亮度、高对比的显示，双面显示面板的光电转化效率较高，与现有技术中双面显示装置的两个单面显示面板均为彩色显示面板相比，可以降低双面显示装置的耗电量。As can be seen from the above, the double-sided display panel provided by the embodiment of the present invention includes a plurality of pixels arranged in an array, each pixel includes a color display pixel 30 and a black and white display pixel 70, and the color side reflective layer 31 of the color display pixel 30 is connected to the black and white display pixel. The black and white side reflective layers 74 of the display pixels 70 are arranged oppositely, so the direction of the light transmitted through the color display pixels 30 is opposite to the direction of the light transmitted through the black and white display pixels 70, so that the display can be displayed on both sides of the double-sided display panel. Picture; the color display pixel 30 includes a color film layer 35, that is to say, the color display pixel 30 can realize color display, and the black and white display pixel 70 does not include a color film layer, that is to say, the black and white display pixel 70 can realize black and white display, and the black and white picture It can be displayed on one side of the light-emitting surface of the black and white display pixel 70 of the above-mentioned double-sided display panel. Since the black and white display pixel 70 does not include a color filter layer, the loss of light emitted by the organic functional layer 72 on the black and white side can be reduced. With a small amount of electricity, high-brightness, high-contrast display can be realized on one side of the light-emitting surface of the black-and-white display pixel 70, and the photoelectric conversion efficiency of the double-sided display panel is relatively high, which is different from the two Compared with the single-sided display panel being a color display panel, the power consumption of the double-sided display device can be reduced.
另外，本发明实施例提供的双面显示面板的一侧可以显示彩色图片、另一侧可以显示黑白图片，当需要显示彩色图片时，则通过双面显示面板的彩色显示像素30的出光面的一侧显示，当需要显示黑白图片时，则通过双面显示面板的黑白显示像素70的出光面的一侧显示，从而使得双面显示面板具有较佳的适用性。In addition, one side of the double-sided display panel provided by the embodiment of the present invention can display color pictures, and the other side can display black and white pictures. Display on one side, when black and white pictures need to be displayed, display on one side of the light emitting surface of the black and white display pixels 70 of the double-sided display panel, so that the double-sided display panel has better applicability.
再者，本发明实施例提供的双面显示面板中，通过在彩色侧有机功能层33的两侧或/和黑白侧有机功能层72的两侧加载电压差，激发彩色侧有机功能层33或/和黑白侧有机功能层72，使彩色侧有机功能层33或/和黑白侧有机功能层72发光，即彩色显示像素30和黑白显示像素70分别为OLED器件，且彩色显示像素30和黑白显示像素70可以同时制作在两个透明基板之间，与现有技术中双面显示装置采用两个单面显示面板相比，简化了双面显示装置的结构，并简化了双面显示装置的制作工艺，降低了双面显示装置的制作难度。Moreover, in the double-sided display panel provided by the embodiment of the present invention, by applying a voltage difference on both sides of the color-side organic functional layer 33 or/and both sides of the black-and-white side organic functional layer 72, the color-side organic functional layer 33 or /and the organic functional layer 72 on the black and white side, so that the organic functional layer 33 on the color side or/and the organic functional layer 72 on the black and white side emit light, that is, the color display pixel 30 and the black and white display pixel 70 are OLED devices respectively, and the color display pixel 30 and the black and white display The pixel 70 can be fabricated between two transparent substrates at the same time, which simplifies the structure of the double-sided display device and simplifies the manufacture of the double-sided display device compared with the double-sided display device in the prior art using two single-sided display panels. process, which reduces the difficulty of manufacturing the double-sided display device.
值得一提的是，当将本发明实施例提供的双面显示面板应用于手机、平板电脑等移动终端时，移动终端的电量较低时，依然可以通过双面显示面板的黑白显示像素70的出光面的一侧查看黑白文字、黑白图片、黑白视频等黑白画面，例如短信，因此，与现有技术中双面显示装置的两个单面显示面板均为彩色显示面板相比，可以防止因移动终端的电量较低而导致用户无法查看黑白画面，防止对用户的工作和生活带来不方便。It is worth mentioning that when the double-sided display panel provided by the embodiment of the present invention is applied to mobile terminals such as mobile phones and tablet computers, when the power of the mobile terminal is low, the black and white display pixels 70 of the double-sided display panel can still be used. One side of the light-emitting surface is used to view black and white text, black and white pictures, black and white video and other black and white pictures, such as text messages. The power of the mobile terminal is low so that the user cannot view the black and white screen, preventing inconvenience to the user's work and life.
