Description

一种液晶面板及液晶面板的制造方法 【技术领域】
本申请涉及显示技术领域，更具体的说，涉及一种液晶面板及液晶面板的制造方法。
【背景技术】
液晶显示器具有机身薄、省电、无辐射等众多优点，得到了广泛的应用。现有市场上的液晶显示器大部分为背光型液晶显示器，其包括液晶面板及背光模组(backlight module)。液晶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，并在两片玻璃基板上施加驱动电压来控制液晶分子的旋转方向，以将背光模组的光线折射出来产生画面。
其中，薄膜晶体管液晶显示器(Thin Film Transistor-Liquid Crystal Display，TFT-LCD)由于具有低的功耗、优异的画面品质以及较高的生产良率等性能，目前已经逐渐占据了显示领域的主导地位。同样，薄膜晶体管液晶显示器包含液晶面板和背光模组，液晶面板包括彩膜基板(Color Filter Substrate，CF Substrate，也称彩色滤光片基板)和薄膜晶体管阵列基板(Thin Film Transistor Substrate，TFT Substrate)，上述基板的相对内侧存在透明电极。两片基板之间夹一层液晶分子(Liquid Crystal，LC)。液晶面板是通过电场对液晶分子取向的控制，改变光的偏振状态，并藉由偏光板实现光路的穿透与阻挡，实现显示的目的。
由于现在液晶面板的窄边框的技术，使得框胶势必得站在配向层上，框胶站在配向层上容易发生尚未固化前提早崩塌的问题，进而影响框胶框度的制程能力。
【发明内容】
本申请所要解决的技术问题是提供一种提高框胶制程能力的液晶面板。
此外，本申请还提供一种采用所述液晶面板的液晶显示器。
另外，本申请还提供一种液晶面板的制造方法。

其中，所述凹槽贯穿黑矩阵；所述凹槽底面为基板。生产加工简单方便，便于生产实施。
其中，所述框胶为黑色框胶。由于在黑矩阵上开设凹槽后会导致漏光，使用黑色框胶进行涂布，以防止漏光。
其中，所述凹槽为盲槽。黑矩阵上开设的凹槽为盲槽，不需要额外的遮光操作，减少工作量，不影响遮光效果。
其中，所述凹槽为连续环绕框胶覆盖区域。凹槽加工简单，连接效果好。
其中，所述凹槽沿框胶覆盖区域间隔设置。
其中，所述凹槽宽度小于框胶宽度。不影响框胶原有功能的情况下限制框胶的宽度，提高框胶的线宽制程能力。
其中，所述液晶面板还包括背光模组，所述背光模组上设置阵列基板，所述阵列基板与彩膜基板相对设置，所述彩膜基板和阵列基板通过框胶连接，所述彩膜基板上还设有与黑矩阵错开设置的彩色滤光层，所述阵列基板与彩膜基板之间设有液晶和PS(photo spacer)，所述阵列基板上设有薄膜晶体管，所述彩色滤光层、液晶、PS(photo spacer)和薄膜晶体管设置在框胶内。

根据本申请的另一个方面，本申请还公开了一种液晶面板法的制造方法， 如上述所述的凹槽采用半色调掩膜工艺在黑矩阵上生成。
黑矩阵对应框胶位置开设凹槽，凹槽底面覆盖有配向层，配向层上设置框胶，框胶在配向层上接触角较大易发生尚未固化前提早崩塌，用凹槽的高低差来牵制框胶在配向层上的崩塌范围便可收敛因接触角所造成的制程变异，提高框胶的线宽制程能力，尤其适合窄边框液晶面板。

下面结合附图和较佳的实施例对本申请作进一步说明。
其中，如附图1a至图1c所示，由于液晶面板的窄边框的技术，使得框胶势必得站在配向层上，因未固化(Curing)的框胶(Seal)站在玻璃基板、黑矩阵 和配向层的接触角不同，框胶在基板上的接触角最小，框胶在黑矩阵上的接触角中等，框胶在基板上的接触角最大，可见框胶站在配向层上容易发生尚未固化前提早崩塌的问题，进而影响框胶框度的制程能力。
其中，如图2a和图2b所示的两种热辅助固化材料的应用(application of the heat auxiliary curable type)，1a为透明框胶；1b为黑色框胶。对比普通透明框胶，黑色框胶具备遮光效果。其中黑色框胶，光密度OD 5um/2.5，BM光密度OD约在4～5。

在黑矩阵11对应框胶14位置开设凹槽13，凹槽13底面覆盖有配向层15，配向层15上设置框胶14，框胶14在配向层15上接触角较大易发生尚未固化前提早崩塌，用凹槽13的高低差来牵制框胶14在配向层15上的崩塌范围便可收敛因接触角所造成的制程变异，提高框胶14的线宽制程能力，尤其适合窄边框液晶面板。
正常情况下UV灯(紫外线灯)照射彩膜基板(CF)侧会被黑矩阵11(BM)遮挡，如今在彩膜基板(CF)的黑矩阵11(BM)开槽就可避免该问题，用来 减少影部硬化不足之问题，还可以减少制程限制，框胶的紫外线固化(UV Curing)可从TFT侧的阵列基板30照射，也可以从彩膜基板(CF)侧照射，窄边框制成固化(Curing)照射CF侧，可以减少影部硬化不足之问题。

凹槽13为连续环绕框胶14覆盖区域。凹槽13加工简单，连接效果好。凹槽13宽度小于框胶14宽度。不影响框胶14原有功能的情况下限制框胶14的宽度，提高框胶14的线宽制程能力。
在黑矩阵11对应框胶14位置开设凹槽13，凹槽13底面覆盖有配向层15，配向层15上设置框胶14，框胶14在配向层15上接触角较大易发生尚未固化前提早崩塌，用凹槽13的高低差来牵制框胶14在配向层15上的崩塌范围便可收敛因接触角所造成的制程变异，提高框胶14的线宽制程能力，尤其适合窄边框液晶面板。正常情况下UV灯(紫外线灯)照射彩膜基板(CF)侧会被黑矩阵 11(BM)遮挡，如今在彩膜基板(CF)的黑矩阵11(BM)开槽就可避免该问题，用来减少影部硬化不足之问题，还可以减少制程限制，框胶的紫外线固化(UV Curing)可从TFT侧的阵列基板30照射，也可以从彩膜基板(CF)侧照射，窄边框制成固化(Curing)照射CF侧，可以减少影部硬化不足之问题。
黑色框胶除了具备框胶原有特性外还须兼顾黑色框胶本身透光度，起到遮光的效果，最好能达到黑矩阵一样的遮光效果，黑色框胶影部硬化性与一般胶材一致或接近，根据黑色框胶对液晶面板工艺和治具进行调整，以符合液晶面板的各项参数指标。
