Description

终端设备 技术领域
本发明涉及显示技术领域，尤其涉及一种终端设备。
 背景技术
随着显示技术的发展，液晶显示器(Liquid Crystal Display，LCD)等平面显示装置因具有高画质、省电、机身薄及应用范围广等优点，而被广泛的应用于手机、电视、个人数字助理、数字相机、笔记本电脑、台式计算机等各种消费性电子产品，成为显示装置中的主流。现有市场上的液晶显示装置大部分为背光型液晶显示器，其包括液晶显示面板及背光模组(backlight module)。液晶显示面板的工作原理是在两片平行的玻璃基板当中放置液晶分子，两片玻璃基板中间有许多垂直和水平的细小电线，通过通电与否来控制液晶分子改变方向，将背光模组的光线折射出来产生画面。 
通常液晶显示面板由彩膜(Color Filter，CF)基板、薄膜晶体管(Thin Film Transistor，TFT)基板、夹于彩膜基板与薄膜晶体管基板之间的液晶(Liquid Crystal，LC)及密封胶框(Sealant)组成，其成型工艺一般包括：前段阵列(Array)制程(薄膜、黄光、刻蚀及剥膜)、中段成盒(Cell)制程(TFT基板与CF基板贴合)及后段模组组装制程(驱动IC与印刷电路板压合)。其中，前段Array制程主要是形成TFT基板，以便于控制液晶分子的运动；中段Cell制程主要是在TFT基板与CF基板之间添加液晶；后段模组组装制程主要是驱动IC压合与印刷电路板的整合，进而驱动液晶分子转动，显示图像。 
触控液晶显示面板依感应技术不同可分为电阻式、电容式、光学式、音波式四种，目前主流的触控技术为电容式，其中电容式又分为自电容式和互电容式，目前市场上的电容式触控显示面板为主要为互电容式，互电容的优点在于可实现多点触控。触控显示面板根据结构不同可划分为外挂式和内嵌式(In-cell)两种：外挂式是将触控感测器制作于彩色滤光片的表面，将触控感应器加上玻璃做成触控面板模组，然后再与液晶面板模组贴合。内嵌式是将触控感测器制作于面板结构中，直接把触控感应器置于薄膜晶体管液晶显示器面板模组中，触控功能整合于显示器内，不必再外挂触控面板，因此其厚度也较外挂式触控面板轻而薄。
现有的触控显示模组采用口字胶将背光模组和液晶面板粘接，将现有的触控显示模组装入手机中框后，由于背光模组的胶框、反射片以及口字胶等透光材料可以将背光模组的光线透射出来，该透射出来的光线会通过手机中框反射到手机表面，导致用户在观看手机时会感受到可视区（View Area）左右两侧有发亮白斑，影响黑色视觉效果。

需要说明的是，本发明的中框 10 包括底部 11 以及与所述底部 11 连接的侧部 12 ；所述侧部 12 在底部 11 围成一凹槽 13 ，所述吸光散热膜 20 覆盖所述底部 11 以及侧部 12 的内表面（即覆盖整个凹槽 13 ），将显示模组 30 放置于凹槽 13 中，当所述显示模组 30 侧面的漏光出射到中框 10 的侧部 12 时，所述吸光散热膜 20 可以吸收显示模组 30 侧面的漏光，从而避免显示模组 30 侧面的漏光经中框 10 的侧部 12 反射到显示模组 30 的表面，避免终端设备的可视区两侧出现发亮白斑，提高终端设备的黑色视觉效果，此外，所述吸光散热膜 20 还可以将显示模组 30 工作时的热量快速散热，降低终端设备工作时的温度，延长使用寿命。
具体的，所述吸光散热膜 20 的颜色为黑色，该黑色对光线有更好的吸收作用。

所述背光模组 31 包括胶框 311 、设于所述胶框 311 中的导光板 312 、设于所述导光板 312 远离显示面板 32 一侧的反射片 313 、设于所述导光板 312 靠近显示面板 32 一侧的光学膜片组 314 以及设于所述胶框 311 上的双面胶 315 ；
由于所述胶框 311 、反射片 313 及双面胶 315 均存在一定程度的透光，例如，背光模组 31 的整体亮度为 11500 尼特（ nit ），胶框 311 与双面胶 315 透射的光线的亮度之和为 690 尼特，反射片 313 透射的光线的亮度为 120 尼特，因此本申请设置吸光散热膜 20 将胶框 311 、反射片 313 及双面胶 315 透射的光线全部吸收掉，防止这些透射的光线经中框 10 的侧部 12 反射到显示模组 30 的表面。
