Description

面板结构及面板制作方法Panel structure and panel manufacturing method 技术领域Technical field
本发明涉及显示技术领域，尤其是涉及一种液晶面板结构及液晶面板制作方法。The present invention relates to the field of display technology, in particular to a liquid crystal panel structure and a liquid crystal panel manufacturing method.
背景技术Background technique
近年来液晶显示面板广泛的应用在各种电子装置上，如何改善视角较窄一直是液晶显示领域所要改善的问题。目前常用的广视角液晶显示技术为横向电场效应(In-Plane Switching, IPS)显示技术及垂直排列（Vertical Alignment, VA）液晶显示技术。而VA液晶显示技术相较于IPS显示技术具有对比高及漏光低的优点。In recent years, liquid crystal display panels have been widely used in various electronic devices. How to improve the narrow viewing angle has always been a problem to be improved in the field of liquid crystal display. At present, the commonly used wide viewing angle liquid crystal display technology is the horizontal electric field effect (In-Plane Switching, IPS) display technology and the vertical alignment (Vertical Alignment, VA) liquid crystal display technology. Compared with IPS display technology, VA liquid crystal display technology has the advantages of high contrast and low light leakage.
多畴垂直配向模式(Multi_domain Vertical Alignment, MVA)是VA液晶显示技术一种，利用彩膜侧的突起实现多畴显示，藉此改善了垂直配向模式的视角。但由于彩膜侧的突起，使突起周围的液晶分子偏向范围被限制，漏光也较严重。而图形化垂直配向模式(Patterned Vertical Alignment, PVA)是在彩膜侧氧化铟锡(ITO)透明电极上制作对应的ITO狭缝(Slit)，不需要制作彩膜侧突起,狭缝的宽度通常8〜15微米左右，实现多畴显示。这种方法大幅度减少了相应的漏光。Multi-domain vertical alignment mode (Multi_domain Vertical Alignment, MVA) is a type of VA liquid crystal display technology that uses protrusions on the color film side to achieve multi-domain display, thereby improving the viewing angle of the vertical alignment mode. However, due to the protrusions on the color film side, the deflection range of the liquid crystal molecules around the protrusions is limited, and light leakage is also serious. The graphical vertical alignment mode (Patterned Vertical Alignment (PVA) is to make corresponding ITO slits on the transparent electrode of indium tin oxide (ITO) on the color film side. There is no need to make color film side protrusions. The width of the slit is usually about 8-15 microns to achieve multi-domain display. This method greatly reduces the corresponding light leakage.
高垂直排列(High Vertical Alignment, HVA)模式也是VA液晶显示技术中其中一种，HVA液晶显示技术是利用像素电极与彩膜基板的公共电形之间的垂直电场来控制液晶层中液晶分子的方向。制作HVA显示面板时，会将金属球混合在封框胶内，涂布在基板的两侧或是左右其中一侧上，使得上下基板电路能够导通，从而在光电场配向制程时能通过此电路对液晶层进行配向，常用的封框胶为聚酯型聚氨酯胶（AU胶）。The High Vertical Alignment (HVA) mode is also one of the VA liquid crystal display technologies. The HVA liquid crystal display technology uses the vertical electric field between the pixel electrode and the common electric shape of the color film substrate to control the liquid crystal molecules in the liquid crystal layer. direction. When making HVA display panels, metal balls are mixed in the sealant and coated on both sides of the substrate or one of the left and right sides of the substrate, so that the upper and lower substrate circuits can be turned on, so that they can pass through the photoelectric field alignment process. The circuit aligns the liquid crystal layer, and the commonly used frame sealing glue is polyester polyurethane glue (AU glue).
如图1所示为常见的HVA显示面板结构，在上板12与下板14之间胶涂AU胶16，在AU胶16中放置金属球18使得上板12与下板14电性导通。在HVA显示面板中，上板12与下板14之间的导通性的好坏大大地影响了显示品质，特别是在滤色彩膜激光(Laser On Color-filter, LOC）工艺中，上下基板的导通性的好坏会关系到液晶配向的成功与否。若上下板无法电性导通，会导致液晶配向效果不良，造成显示效果差或无法正常显示。Figure 1 shows a common HVA display panel structure. AU glue 16 is glued between the upper board 12 and the lower board 14. A metal ball 18 is placed in the AU glue 16 to make the upper board 12 and the lower board 14 electrically conductive. . In the HVA display panel, the conductivity between the upper plate 12 and the lower plate 14 greatly affects the display quality, especially in the laser on color-filter (Laser On Color-filter, In the LOC process, the conductivity of the upper and lower substrates will affect the success of the liquid crystal alignment. If the upper and lower plates cannot be electrically connected, the liquid crystal alignment effect will be poor, resulting in poor display effect or abnormal display.
HVA显示面板中的金属球18通常是在塑胶材质球状颗粒表面镀金形成，因此金属球18是具有弹性并且可压缩的，同时AU胶16也同样具有弹性，因此当上板12与下板14贴合时，金属18球会被压缩使上板12与下板14可电性导通。The metal ball 18 in the HVA display panel is usually formed by gold plating on the surface of plastic spherical particles. Therefore, the metal ball 18 is elastic and compressible, and the AU glue 16 is also elastic. Therefore, when the upper board 12 and the lower board 14 are attached At this time, the metal 18 ball will be compressed so that the upper plate 12 and the lower plate 14 can be electrically connected.
由于上板12与下板14之间有很多膜层，即AU胶涂布位置空间高度不一致，且由于制程冗余量的限制（比如基板弯曲或重压的状况下），上下基板不同位置的压合程度不一致，会导致不同位置的金属球18被压缩程度不一致，如图2所示。Because there are many film layers between the upper board 12 and the lower board 14, that is, the height of the AU glue coating position is inconsistent, and due to the limitation of process redundancy (for example, under the condition of substrate bending or heavy pressure), the upper and lower substrates have different positions The inconsistency in the degree of compression will result in inconsistent compression of the metal balls 18 at different positions, as shown in FIG. 2.
技术问题technical problem
请参考图3，在上板12与下板14之间分别各具有一层ITO透明电极层102，此外，在显示面板中可能具有更多的膜层，如金属线层104及绝缘层106，在有些膜层结构中，由于显示面板中还有其他膜层与部件，会使上板与下板之间的两层ITO透明电极层102距离过宽，或因外力使得显示面板弯曲，使得上板12与下板14之间的金属球18没有被压缩，若金属球18不能被压缩，则上下的ITO透明电极层无法被导通，使得面板无法正常显示。Please refer to FIG. 3, there is a layer of ITO transparent electrode layer 102 between the upper plate 12 and the lower plate 14 respectively. In addition, there may be more layers in the display panel, such as a metal wire layer 104 and an insulating layer 106. In some film structures, because there are other films and components in the display panel, the distance between the two ITO transparent electrode layers 102 between the upper plate and the lower plate is too wide, or the display panel is bent due to external force, which makes the upper plate The metal ball 18 between the board 12 and the lower board 14 is not compressed. If the metal ball 18 cannot be compressed, the upper and lower ITO transparent electrode layers cannot be conducted, making the panel unable to display normally.
因此，需要一种面板结构，来确保位于AU胶层中的金属球可以被压缩，使得上下基板间相互导通。Therefore, a panel structure is needed to ensure that the metal balls located in the AU glue layer can be compressed, so that the upper and lower substrates are connected to each other.

The black matrix 410 is disposed between the first substrate 42 and the first transparent electrode layer 400 to connect the first transparent electrode layer 400 pushes toward the second transparent electrode layer 402, so that the distance between the first transparent electrode layer 400 and the second transparent electrode layer 402 is shortened, so as to ensure that the first transparent electrode layer 400 and the second transparent electrode layer 402 are electrically conductive. Ball 48 makes electrical contact.
在本发明较佳的实施例中，显示面板40的制程中利用LOC工艺来形成彩膜，因此黑色矩阵410的区域不能与LOC工艺中使用激光的区域重迭，避免影响LOC制程的效果。In a preferred embodiment of the present invention, the LOC process is used to form the color film in the manufacturing process of the display panel 40, so the area of the black matrix 410 cannot overlap with the area where the laser is used in the LOC process to avoid affecting the effect of the LOC process.

According to the structure of the panel and the spacing of the transparent electrodes, a color resist layer may also be provided between the first transparent electrode 400 and the black matrix 410 in FIG. A color resist layer is arranged between the substrate 42 and the black matrix 410, thereby further shortening the distance between the two transparent electrode layers. Similarly, under the premise of not affecting the circuit conduction and display effect of the display panel, the second substrate 44, the metal wire layer 404, the insulating layer 406 or the second transparent electrode layer 402 in FIG. 4 can also be arranged between any two layers. The black matrix shortens the distance between the first transparent electrode layer 400 and the second transparent electrode layer 402.
