发明内容
鉴于此,有必要提供一种双面式液晶显示模组,所述双面式液晶显示模组包括第一显示模组、第二显示模组以及同时为所述第一显示模组与第二显示模组提供背光的背光模组,所述第一显示模组用于在所述双面式液晶显示模组的正面显示画面,所述第二显示模组用于在所述双面式液晶显示模组的背面显示画面,所述背光模组位于所述第一显示模组与第二显示模组之间,其特征在于,所述背光模组包括光源、导光板以及反光片,所述光源发出的光线通过导光板传导至所述反光片的上下两侧并被所述反光片反射至所述第一显示模组与第二显示模组。
与现有技术相对比,本发明所提供的双面式液晶显示模组只需要一个光源即可同时即可实现对所述第一显示模组与所述第二显示模组提供亮度,同时,该双面式液晶显示模组的厚度也被有效地降低。

所述光源276发出的一部分光线通过所述第一导光板271传导至所述反光片273靠近所述第一显示模组250的一侧,并被所述反光片273反射,经过所述第一光学膜片274的调制后传导至所述第一显示模组250。所述光源276发出的另一部分光线通过所述第二导光板272传导至所述反光片273靠近所述第二显示模组260的一侧,并被所述反光片273反射,经过所述第二光学膜片275的调制后传导至所述第二显示模组260。
所述胶框220位于所述第一显示模组250、背光模组270以及第二显示模组260所形成的整体的一侧。所述胶框220包括向所述第一显示模组250延伸的第一凸块221以及向所述第二显示模组260延伸的第二凸块222。所述第一阵列基板251面向所述背光模组270的一侧抵持在所述第一凸块221上。所述第二阵列基板261面向所述背光模组270的一侧抵持在所述第二凸块222上。
所述外框210位于由所述盖板230、第一显示模组250、背光模组270、第二显示模组260以及胶框220所形成的整体的一侧。所述胶框220远离所述背光模组270的一侧紧贴在所述外框210上。所述盖板230靠近所述外框210的一端被所述外框210的一第一表面211所支撑。所述外框210包括第三凸块213。所述第三凸块213位于所述外框210远离所述盖板230的一侧,并向所述第四偏光片265延伸。所述胶框220的底端以及所述第四偏光片265置于所述第三凸块213上,并被所述第三凸块213所支撑。
请一并参阅图4与图5。在本实施方式中,所述光源276能够在从所述第一显示模组250至所述第二显示模组260的方向上来回移动。所述光源276移动的方式包括但不限于齿轮或螺杆结构。通过所述光源276的移动,能够调节所述光源276照射向所述第一导光板271与第二导光板272的亮度,进而调节所述第一显示模组250与第二显示模组260的亮度。举例而言,如图4所示,当所述光源276向所述第一显示模组250的方向移动时,所述光源276照在所述第一导光板271上的亮度会增加,而照在所述第二导光板272上的亮度会降低。进而,经由所述反光片273反射后的光线照射在所述第一显示模组250上的亮度会高于照射在所述第二显示模组260上的亮度。同样地,如图5所示,当所述光源276向所述第二显示模组260的方向移动时,所述光源276照在所述第二导光板272上的亮度会增加,而照在所述第一导光板271上的亮度会降低。进而,经由所述反光片273反射后的光线照射在所述第二显示模组260上的亮度会高于照射在所述第一显示模组250上的亮度。
本发明所提供的双面式液晶显示模组200,由于所述第一显示模组250与所述第二显示模组260共用所述背光模组270,且所述背光模组270中光源276发出的光线被所述反光片273一分为二照射至所述第一显示模组250与所述第二显示模组260。因此,该双面式液晶显示模组200仅需要一个光源276即可实现对所述第一显示模组250与所述第二显示模组260提供亮度。从而,该双面式液晶显示模组200的厚度有效地被降低。
以上实施例仅用以说明本发明的技术方案而非限制,图示中出现的上、下、左及右方向仅为了方便理解,尽管参照较佳实施例对本发明进行了详细说明,本领域的普通技术人员应当理解,可以对本发明的技术方案进行修改或等同替换,而不脱离本发明技术方案的精神和范围。
