Description
本發明是有關於LCD顯示技術領域,特別是有關於一種LCD顯示面板及其顯示裝置。 The present invention relates to the technical field of LCD display, and in particular to an LCD display panel and a display device thereof.
液晶顯示器(Liquid Crystal Display,LCD)是利用液晶的電光效應調製外界光線進行顯示的器件。LCD顯示器所採用的顯示面板通常使用兩片基板,並在兩片基板之間填充顯示分子層。如在TFT-LCD(TFT,Thin Film Transistor)顯示面板製程中,首先在第一基板上塗佈密封體(Seal),將第一基板與第二基板對組形成顯示面板基板,然後將其沿切割線進行切割,形成多個基板單元,再對基板單元進行移除部分第二基板、壓焊電子元件、注入顯示分子層等後續工序,形成顯示面板單元(cell)。 Liquid crystal display (Liquid Crystal Display, LCD) is a device that uses the electro-optical effect of liquid crystal to modulate external light for display. The display panel used in the LCD display usually uses two substrates, and a display molecular layer is filled between the two substrates. For example, in the process of a TFT-LCD (Thin Film Transistor) display panel, a seal is first coated on the first substrate, and the first substrate and the second substrate are grouped to form a display panel substrate. The cutting line is cut to form a plurality of substrate units, and then the substrate unit is subjected to subsequent processes such as removing a part of the second substrate, pressure-welding electronic components, and injecting a display molecular layer to form a display panel cell.
在對顯示面板基板的切割過程中,特別是在窄邊框(Slim Border)顯示面板的切割過程中,需要在框膠上方切割(Cutting on Seal),密封體(Seal)中的支撐纖維(Fiber)結構對第二基板會造成阻力,破壞顯示面板結構,進而形成顯示色差(AG mura)。當前窄邊框設計中必須面對這種由於支撐纖維的阻力而造成的顯 示色差問題。 In the cutting process of the display panel substrate, especially in the cutting process of the narrow border display panel, it is necessary to cut (Cutting on Seal) above the sealant, and the support fiber in the seal (Fiber). The structure will cause resistance to the second substrate, destroy the display panel structure, and then form a display color difference (AG mura). The current narrow frame design must face this kind of display caused by the resistance of the supporting fiber. Display of color problems.

為使本發明的上述目的、特徵和優點能夠更加明顯易懂,下面結合附圖對本發明的具體實施方式做詳細的說明。在下面的描述中闡述了很多具體細節以便於充分理解本發明。但是本發明能夠以很多不同於在此描述的其他方式來實施,本領域技術人員可以在不違背本發明內涵的情況下做類似改進,因此本發明不受下面公開的具體實施例的限制。 In order to make the foregoing objects, features, and advantages of the present invention more comprehensible, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. Numerous specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the meaning of the present invention, so the present invention is not limited by the specific embodiments disclosed below.
於本發明實施例中,LCD顯示面板800主要包含第一基板100(如CF基板,CF Substrate)、第二基板200(如TFT 基板,TFT Substrate)、顯示分子層400和密封體300;其中密封體300包含支撐纖維(fiber)301,該支撐纖維301用於提供支撐、提升膜層間接著度等作用,其材質可以為矽膠球(silica ball)、玻璃纖維、金(Au)、二氧化矽(Silica)等,但本發明並不以此為限。第一基板100與第二基板200相對設置,且第一基板100和第二基板200可共同定義顯示區A1和周邊區A2。密封體300設置於第一基板100周邊區A2位置,顯示分子層400設置於顯示區A1位置。為保持第一基板100與第二基板200之間的層間間隙以容納顯示分子層400,在第一基板100上還設置有間隔單元以使該層間間隙的寬度為G。當沿密封體300垂直投影範圍內的切割線P對顯示面板800進行切割時,密封體300內的支撐纖維310會對切割刀片形成阻力,造成第二基板200的破損,進而導致顯示色差(AG mura)。 In the embodiment of the present invention, the LCD display panel 800 mainly includes a first substrate 100 (such as a CF substrate) and a second substrate 200 (such as a TFT). Substrate, TFT Substrate), display molecular layer 400, and sealing body 300; wherein the sealing body 300 includes a support fiber 301, which is used to provide support and improve the indirect visibility of the film layer, and the material can be a silicone ball (silica ball), glass fiber, gold (Au), silicon dioxide (Silica), etc., but the invention is not limited thereto. The first substrate 100 and the second substrate 200 are oppositely disposed, and the first substrate 100 and the second substrate 200 may collectively define a display area A1 and a peripheral area A2. The sealing body 300 is disposed at the position of the peripheral region A2 of the first substrate 100, and the display molecular layer 400 is disposed at the position of the display region A1. In order to maintain an interlayer gap between the first substrate 100 and the second substrate 200 to accommodate the display molecular layer 400, a spacer unit is further provided on the first substrate 100 so that the width of the interlayer gap is G. When the display panel 800 is cut along the cutting line P in the vertical projection range of the sealing body 300, the supporting fibers 310 in the sealing body 300 will form a resistance to the cutting blade, cause the second substrate 200 to be damaged, and further cause display color difference (AG mura).
本發明的實施例藉由在第二基板200上設置凸出結構210,以改變不同位置的間隔單元的厚度,使位於密封體300的間隔單元與第二基板200之間存在可以容納支撐纖維310的讓位間隙,以避免在密封體300上方切割時由於支撐纖維310阻力造成的顯示面板結構破壞。 In the embodiment of the present invention, a protruding structure 210 is provided on the second substrate 200 to change the thickness of the spacer units at different positions, so that there is a space between the spacer units located in the sealing body 300 and the second substrate 200 to accommodate the support fibers 310 To avoid the display panel structure being damaged due to the resistance of the supporting fiber 310 when cutting over the sealing body 300.

As shown in FIG. 1, in this embodiment, at a position corresponding to the display area A1, the first substrate 100 is provided with a first spacer unit 510, where the first spacer unit 510 includes a light shielding layer 501, a color resist layer 502, and a cover layer 503.
