Description
本發明係關於一種面板結構及其製造方法,特別是一種藉由改良面板結構以增加間隙柱高度,用以穩定面板製程之可增加間隙柱高度的面板結構及其製造方法。The invention relates to a panel structure and a manufacturing method thereof, in particular to a panel structure capable of increasing the height of a gap pillar by improving the panel structure to stabilize the panel manufacturing process and a manufacturing method thereof.
在面板製程中,半穿透半反射(Transflective)面板技術係一種可同時利用背光模組之穿透光與環境光源之反射光進行顯示的技術,使液晶面板在強烈的光環境中具有可視性。當背光模組電源關閉不提供光源時,液晶面板也可藉由此環境中的光反射產生顯示資訊,藉此節省耗電。相較於習知僅使用穿透光或僅使用環境光顯示的液晶面板而言,半穿透半反射面板技術會結合習知技術的特性及優點,使得具有半穿透半反射的液晶面板,運用在一般可攜式電子裝置時,足以靈活運用在各種不同的光環境中。因此,現今半穿透半反射面板已經普遍應用在智慧型手機、平板電腦等行動裝置中。In the panel manufacturing process, Transflective panel technology is a technology that can simultaneously use the transmitted light of the backlight module and the reflected light of the ambient light source to display, so that the liquid crystal panel has visibility in a strong light environment . When the backlight module is powered off and no light source is provided, the liquid crystal panel can also generate display information by light reflection in the environment, thereby saving power consumption. Compared with the conventional liquid crystal panels that only use transmissive light or only ambient light for display, the transflective semi-reflective panel technology combines the characteristics and advantages of the conventional technology to make the transflective liquid crystal panel, When used in general portable electronic devices, it is flexible enough to be used in various light environments. Therefore, nowadays, semi-transmissive and semi-reflective panels have been widely used in mobile devices such as smart phones and tablet computers.
其中一種半穿透半反射面板在進行畫素設計時,同時具有兩種不同的液晶盒間隙(Cell Gap),而半穿透半反射面板較注重反射光學特性之一,其分類係為微穿透(Micro-Transmitted)面板。請參照第一圖所示,在此一習知面板結構10的設計中,主要係利用位在上有機組合層12、下有機組合層14及其間的間隙柱16形成反射液晶盒間隙,再配合反射率及顏色的調整,間隙柱16的高度會在0.8~2.2μm間,若間隙柱16的高度不夠或太低,會造成面板製程產生不穩定。One type of semi-transmissive and semi-reflective panel has two different liquid cell gaps (Cell Gap) during pixel design, and the semi-transmissive and semi-reflective panel pays more attention to one of the reflective optical characteristics, and its classification is micro-pass (Micro-Transmitted) panel. Please refer to the first figure. In the design of this conventional panel structure 10, the reflective liquid crystal cell gap is mainly formed by using the upper organic combination layer 12, the lower organic combination layer 14 and the gap posts 16 therebetween, and then cooperate For the adjustment of reflectivity and color, the height of the gap pillar 16 will be between 0.8 and 2.2 μm. If the height of the gap pillar 16 is not enough or too low, it will cause instability in the panel manufacturing process.
然而,一般微穿透面板結構,最理想的是Cell Gap與間隙柱同高,若在此結構下,基板進行製程完成後表面為平整,則間隙柱高度會等於反射光學Cell Gap,若當完成時為高低起伏不平整,就需要依照實際情況調整間隙柱高度,但因為在微穿透面板的間隙柱高度低,在製程上具有相當的困難度,不易達成理想的高度,導致面板製程的不穩定。However, for a general micro-penetrating panel structure, it is most ideal that the Cell Gap is the same height as the gap pillar. If the surface of the substrate is flat after the manufacturing process is completed in this structure, the height of the gap pillar will be equal to the reflective optical cell gap. When the height is uneven, the height of the gap column needs to be adjusted according to the actual situation. However, because the height of the gap column in the micro-penetrating panel is low, it is quite difficult in the manufacturing process, and it is difficult to achieve the ideal height. stable.
因此,本發明基於上述習知微穿透面板結構設計間隙柱高度的難度,進行結構及製造方法的改善,以提出一種可增加間隙柱高度的面板結構及其製造方法。Therefore, the present invention improves the structure and manufacturing method based on the difficulty of designing the height of the gap pillars of the above-mentioned conventional micro-penetrating panel structure, and proposes a panel structure and a manufacturing method thereof that can increase the height of the gap pillars.

The number of grooves 341 corresponds to the structure shown in the fifth figure. The present invention does not limit the number of grooves 341. As shown in step S22, and referring to FIG. 7b, a first substrate 32 is provided, for example, a first light-transmitting layer 326 is provided first, then a color resist layer 324 is formed on the first light-transmitting layer 326, and then a first organic The material layer 322 is on the color resist layer 324 to form the first substrate 32, which corresponds to the number of grooves 341 to form the gap pillars 36 on the first organic material layer 322. The present invention does not limit the number of gap pillars 36 . As shown in step S24, and referring to FIG. 36 places between the first substrate 32 and the second substrate 34.
上述的二實施例,一是利用移除第二基板中的部分第二有機材料層之方式形成凹槽,二是利用移除第二基板中的部分第一合金層之方式,使得上面堆疊各階層後以形成凹槽,可以透過蝕刻或曝光顯影的方式移除部分第二有機材料層及部分第一合金層。在此,又提出另一實施例以供說明,例如結合上述兩種實施例的方式,在形成第一合金層時,先透過曝光顯影的方式形成至少一缺口,接著進行第二有機材料層的堆疊,此時可以更進一步決定,一旦當所設置的間隙柱高度過高時,可以再藉由如蝕刻製程的方式,在第二有機材料層進行部分的移除,並以形成凹槽。此時的凹槽則是結合上述兩種移除方式所產生,使用者可以依照自己生產所需的製程進行調整,本發明則不限制應要使用何種方式,也不限制要移除的第一合金層或有機材料層被移除的深度。In the above two embodiments, one is to form a groove by removing part of the second organic material layer in the second substrate, and the second is to remove part of the first alloy layer in the second substrate so that After the layers are formed to form grooves, part of the second organic material layer and part of the first alloy layer can be removed by etching or exposure and development. Here, another embodiment is provided for illustration. For example, in combination with the above two embodiments, when forming the first alloy layer, at least one notch is formed through exposure and development, and then the second organic material layer is formed. For stacking, it can be further determined at this time that once the height of the gap pillar is too high, the second organic material layer can be partially removed by a process such as an etching process to form a groove. At this time, the groove is generated by combining the above two removal methods, and the user can adjust according to the production process required by the user. The present invention does not limit which method should be used, nor does it limit the removal of the first The depth to which an alloy layer or organic material layer is removed.
本發明主要是利用移除間隙柱下方的部分空間,例如部分的合金層或有機材料層,藉此提高間隙柱可以容置在液晶盒間隙(Cell Gap)的高度,並且提高面板製程的穩定性。在移除合金層或是有機材料層的部分時,只要利用原本即有的光罩搭配如蝕刻的方式即可形成一凹槽,由於合金層的厚度較薄,因此在移除部分的合金層僅能作凹槽深度的微調,主要是藉由有機材料層決定,使用者只要調整曝光量即可達到凹槽深度深淺的控制,並使間隙柱部分高度容置在凹槽內。本發明並不限制所挖掘的凹槽深度,也不限制應該要移除合金層或是有機材料層之部分,只要至少二者擇一即可,但在進行製程中原有的光罩時,及設計將合金層形成的凹陷大小,使得間隙柱的側邊必須要與凹槽產生距離,例如,請參本發明第八圖所示,其中間隙柱36位在凹槽341底部時,位於此一接觸面的間隙柱36需與凹槽341形成一距離L,在本發明中距離L係可為0~20μm,而液晶盒間隙的高度則看使用者製程而定,主要經由本發明可以增加間隙柱的高度,藉此穩定面板的光學特性以及製程效果。The present invention mainly utilizes the removal of part of the space below the gap pillar, such as part of the alloy layer or organic material layer, thereby increasing the height at which the gap pillar can be accommodated in the cell gap and improving the stability of the panel manufacturing process . When removing the part of the alloy layer or the organic material layer, a groove can be formed by using the existing photomask and the method such as etching. Because the thickness of the alloy layer is thin, the alloy layer in the removed part Only fine adjustment of the depth of the groove is mainly determined by the organic material layer. The user can achieve the control of the depth of the groove by adjusting the exposure amount, and the height of the gap column is accommodated in the groove. The invention does not limit the depth of the excavated groove, nor does it limit the part where the alloy layer or the organic material layer should be removed, as long as at least one of the two is selected, but in the original photomask during the manufacturing process, and Design the size of the depression formed by the alloy layer, so that the side of the gap column must be away from the groove, for example, refer to the eighth figure of the present invention, where the gap column 36 is located at the bottom of the groove 341 The gap pillar 36 of the contact surface needs to form a distance L with the groove 341. In the present invention, the distance L can be 0-20 μm, and the height of the gap of the liquid crystal cell depends on the user's manufacturing process. The gap can be increased mainly through the present invention. The height of the pillars to stabilize the optical characteristics of the panel and the process effect.
