具体的，扶强材30的材料包括但不限于聚对苯二甲酸乙二酯（Polyethylene Terephthalate, PET）、环烯烃聚合物(Cyclo olefin polymer, COP)等。
本揭露的一实施例的双面显示面板1000的结构，其中所述第一背板10与所述扶强材30之间还包括一散热材40。
具体的，散热材40可以是铜/石墨发泡复合材料(Copper & Graphite & Foam) ，本发明不限于此。
本揭露的一实施例的双面显示面板1000的结构，其中所述散热材40的边缘与所述第一背板10、所述扶强材30及所述第二背板20的边缘彼此对齐。
本揭露的一实施例的双面显示面板的结构，其中所述第一显示面板100的一边缘与所述第二显示面板200的一边缘彼此对齐。
具体的，双面显示面板1000还可包括触控面板50、触控面板的软性电路板70、偏光片80、玻璃外盖60等，本发明不限于此。
请参阅图5，本揭露还提出了一种双面显示面板的制造方法，包括步骤S101：提供一背板结构、步骤S102：提供一第一显示面板、一第二显示面板及一电连接于所述第一显示面板与所述第二显示面板的一可挠性电路板、步骤S103：将所述第一显示面板固定于所述背板结构的一表面、以及步骤S104：将所述第二显示面板固定于所述背板结构的另一表面。
请参阅图5与图6，其中，步骤S101：提供所述背板结构的步骤，包括步骤S101-1：提供一第一背板、步骤S101-2：提供一扶强材、步骤S101-3：将所述第一背板固定于所述扶强材的一表面、步骤S101-4：提供一第二背板、以及步骤S101-5：将所述第二背板固定于所述扶强材的另一表面。其中所述第一背板、所述扶强材及所述第二背板的边缘彼此对齐。
请参阅图4与图3，具体的，将扶强材30对准第一背板10的边缘贴合，制程容易且精度好控制。将第二背板20对准扶强材30的边缘贴合，制程容易且精度好控制。因为第二面板200此时尚未与第二背板20贴合，所以位于第一面板100与第二面板200之间的可挠性电路板300在此过程中并不会干扰贴合动作的精准度。将背板结构400组装完毕后，再来将第二面板200贴合至背板结构400，此时只需对准第二面板200与第一面板100即可。
请参阅图3，本揭露的一实施例的双面显示面板制造方法，其中将所述第一显示面板固定于所述背板结构的一表面的步骤中，将所述第一显示面板100固定于所述背板结构400的所述第一背板10的一表面。
具体的，所述第一背板10与所述扶强材30之间还包括一散热材40。
本揭露的一实施例的双面显示面板制造方法，其中将所述第二显示面板固定于所述背板结构的另一表面的步骤中，将所述第二显示面板200固定于所述背板结构400的所述第二背板20的一表面。
本揭露的双面显示面板的背板结构、双面显示面板及双面显示面板的制作方法，保证了两段背板之间平齐，避免错位，改善圆弧形状，提升圆弧半径R精度，提升产品可靠性。本揭露通过所述第一背板、所述扶强材及所述第二背板的边缘彼此对齐，解决现有背板结构容易出现错位，可挠性电路板弯折后存在圆弧形状不佳，半径R精度不稳定的技术问题。
