Description
本發明係關於排出液晶到界定於母基板上之面板區域之塗佈機。The present invention relates to a coater for discharging liquid crystals to a panel region defined on a mother substrate.
液晶是結晶固體與等向性液體間的中間相,並結合了晶體結構與變形流體的某些特性。液晶顯示器(LCD)利用液晶的流體性與結晶特性相關的非等向性。液晶顯示器應用於手機、可攜式電腦、桌上型監視器、以及LCD電視。Liquid crystals are intermediate phases between crystalline solids and isotropic liquids and combine certain properties of crystal structures and deformed fluids. Liquid crystal displays (LCDs) utilize the anisotropy associated with the fluidity of liquid crystals and the crystallization characteristics. Liquid crystal displays are used in mobile phones, portable computers, desktop monitors, and LCD TVs.
液晶顯示器由TFT陣列基板、彩色濾光片陣列基板、以及夾設於其間的液晶層所構成。The liquid crystal display is composed of a TFT array substrate, a color filter array substrate, and a liquid crystal layer interposed therebetween.
藉由控制施加於各像素之液晶層的電壓,可容許不同量的光通過,而構成不同程度的灰階。By controlling the voltage applied to the liquid crystal layer of each pixel, different amounts of light can be allowed to pass, and different degrees of gray scale are formed.
液晶塗佈機用以塗佈液晶於TFT陣列基板及彩色濾光片陣列基板任一者上,於後稱為「母基板(M)」。The liquid crystal coater is used to apply liquid crystal on either of the TFT array substrate and the color filter array substrate, and is hereinafter referred to as "mother substrate (M)".
母基板上界定有面板區域。液晶塗佈機塗佈參考液晶量於各面板區域。A panel area is defined on the mother substrate. The liquid crystal coater applies a reference liquid crystal amount to each panel region.
圖1A、圖1B、及圖1C為顯示習知液晶塗佈機自噴嘴滴落液晶滴於母基板上界定的面板區域U之示意圖。1A, 1B, and 1C are schematic views showing a panel region U defined by a conventional liquid crystal coater dropping liquid crystal droplets from a nozzle on a mother substrate.
如圖1A所示,液晶塗佈機自定位於預定面板區域U上方之噴嘴N滴落液晶滴D。As shown in FIG. 1A, the liquid crystal coater drops the liquid crystal droplet D from the nozzle N positioned above the predetermined panel area U.
如圖1B所示,液晶滴碰撞面板區域,使其形狀迅速地改變。結果,迫使液晶滴的若干部分破成碎片P。同時,空氣取代了液晶滴的若干部分,藉此困陷在剩餘液晶滴內部。As shown in FIG. 1B, the liquid crystal droplets collide with the panel region, causing its shape to change rapidly. As a result, portions of the liquid crystal droplets are forced to break into pieces P. At the same time, air replaces portions of the liquid crystal droplets, thereby trapping inside the remaining liquid crystal droplets.
如圖1C所示,碎片P彈離面板區域並落在其他地方。As shown in Figure 1C, the debris P bounces off the panel area and falls elsewhere.
碎片P可能落在形成於面板區域周圍之矩形密封劑圖案上。如此於後續附接程序中,使兩個母基板不能彼此好好的附接。碎片P可能落在矩形密封劑圖案外。如此使得面板區域U的參考液晶量短缺。The debris P may fall on a rectangular sealant pattern formed around the panel area. In the subsequent attachment procedure, the two mother substrates are not attached to each other well. The debris P may fall outside the rectangular sealant pattern. This makes the reference liquid crystal amount of the panel area U short.
接著,困陷在液晶滴內部的空氣A,使得夾設在兩個母基板間之液晶層產生空氣泡。Then, the air A trapped inside the liquid crystal droplets causes the liquid crystal layer interposed between the two mother substrates to generate air bubbles.
因為液晶滴以相當大的衝擊落在面板區域,所以在兩個母基板M附接後,在LCD面板上呈現有液滴記號S。Since the liquid crystal droplets fall in the panel region with a considerable impact, after the two mother substrates M are attached, the liquid droplet marks S are presented on the LCD panel.
因此,本發明目的在於塗佈與參考液晶量相同的液晶量於母基板上界定的各面板區域。Accordingly, it is an object of the present invention to coat the respective panel regions defined on the mother substrate with the same amount of liquid crystal as the reference liquid crystal.
本發明之目的在於滴落等於參考液晶量的複數滴液晶於母基板上界定的各面板區域。It is an object of the present invention to drop a plurality of liquid crystals equal to the reference liquid crystal amount on each of the panel regions defined on the mother substrate.
本發明另一目的在於避免空氣困陷於液晶滴內。Another object of the invention is to avoid trapping air within the liquid crystal droplets.
本發明另一目的在於避免兩個母基板彼此附接後,液滴記號呈現於LCD面板。Another object of the present invention is to prevent the droplet marks from being present on the LCD panel after the two mother substrates are attached to each other.

The connecting pipe 920 is connected between the inlet 911 and the outlet 912. Piezoelectric device 930 vibrates connection tube 920. Cable 940 carries current to piezoelectric device 930. The first shock absorber 951 is located between the connecting pipe 920 and the inlet 911. The second shock absorber 952 is located between the connecting tube 920 and the outlet 912.
入口911利用管件990連接流出口323。經由流出口323排出之液晶,透過管件990與入口911,流入連接管920。The inlet 911 is connected to the outflow port 323 by a pipe 990. The liquid crystal discharged through the outflow port 323 passes through the tube 990 and the inlet 911 and flows into the connection pipe 920.
甜甜圈形式的壓電裝置930插入殼體910並包圍連接管920。壓電裝置930可為任何能震動連接管920的形式。當施加電場時,壓電裝置930產生機械應力,藉此震動連接管920。A piezoelectric device 930 in the form of a donut is inserted into the housing 910 and surrounds the connecting tube 920. Piezoelectric device 930 can be in the form of any vibrating connection tube 920. When an electric field is applied, the piezoelectric device 930 generates mechanical stress, thereby vibrating the connection tube 920.
透過纜線940供應到壓電裝置930之電流的頻率越高,連接管920就越常震動。連接管920震動的頻率可比20KHz還大。The higher the frequency of the current supplied to the piezoelectric device 930 through the cable 940, the more the connection tube 920 vibrates. The connection tube 920 can vibrate at a frequency greater than 20 KHz.
連接管920的震動造成流入連接管920之液晶震動。如此使得液晶L破成非常小的粒子C。The vibration of the connecting tube 920 causes the liquid crystal flowing into the connecting tube 920 to vibrate. This causes the liquid crystal L to break into very small particles C.
結果透過出口912噴塗液晶L。As a result, liquid crystal L is sprayed through the outlet 912.
第一吸震器951及第二吸震器952避免殼體910於連接管920震動時震動。可不提供第一吸震器951及第二吸震器952。於此情況下,殼體910也會震動。第一吸震器951及第二吸震器952可由能吸收震動的橡膠製成。The first shock absorber 951 and the second shock absorber 952 prevent the housing 910 from vibrating when the connecting tube 920 vibrates. The first shock absorber 951 and the second shock absorber 952 may not be provided. In this case, the housing 910 also vibrates. The first shock absorber 951 and the second shock absorber 952 may be made of rubber capable of absorbing vibration.
現說明噴塗液晶於母基板上界定的面板區域之操作。The operation of spraying the liquid crystal on the panel area defined on the mother substrate will now be described.
如圖3及圖4所示,旋轉驅動單元700轉動活塞400,使得活塞400之溝槽430面對圓筒之流入口322。一旦溝槽430面對流入口322,旋轉驅動單元700停止轉動活塞400。As shown in FIGS. 3 and 4, the rotary drive unit 700 rotates the piston 400 such that the groove 430 of the piston 400 faces the inlet 322 of the cylinder. Once the groove 430 faces the inflow port 322, the rotary drive unit 700 stops rotating the piston 400.
線性驅動單元800向上移動旋轉驅動單元700一段預定距離。如此也會向上移動活塞400。The linear drive unit 800 moves the rotary drive unit 700 upward by a predetermined distance. This also moves the piston 400 up.
抽吸空間為活塞底側與活塞孔321中之蓋件340上側形成的。活塞400向上移動越高,抽吸空間越大,且活塞孔321中的壓力變得越低。圓筒內部及外部間的壓差,使得瓶器520中的液晶透過第一管530及流入口322流入抽吸空間。The suction space is formed on the bottom side of the piston and the upper side of the cover member 340 in the piston hole 321 . The higher the piston 400 moves upward, the larger the suction space, and the lower the pressure in the piston bore 321 becomes. The pressure difference between the inside and the outside of the cylinder causes the liquid crystal in the bottle 520 to flow into the suction space through the first tube 530 and the inflow port 322.
一旦活塞400向上移動預定距離,線性驅動單元800停止向上移動活塞400。然後,旋轉驅動單元700轉動活塞400,使活塞400的溝槽430面對圓筒320的流出口323。Once the piston 400 is moved upward by a predetermined distance, the linear drive unit 800 stops moving the piston 400 upward. Then, the rotary drive unit 700 rotates the piston 400 such that the groove 430 of the piston 400 faces the outflow port 323 of the cylinder 320.
一旦溝槽430面對流出口323,旋轉驅動單元700停止轉動活塞400。Once the groove 430 faces the outflow port 323, the rotary drive unit 700 stops rotating the piston 400.
線性驅動單元800向下移動旋轉驅動單元700一段預定距離。如此也會向下移動活塞400。The linear drive unit 800 moves the rotary drive unit 700 downward by a predetermined distance. This will also move the piston 400 down.
活塞400向下移動越低,抽吸空間越小。活塞400向下移動迫使抽吸空間內的液晶透過流出開口323排出到外面。The lower the piston 400 moves downward, the smaller the suction space. The downward movement of the piston 400 forces the liquid crystal in the suction space to be discharged to the outside through the outflow opening 323.
如圖7所示,經由流出口323排出之液晶,透過管件990及噴塗單元900之入口911流入連接管920。As shown in FIG. 7, the liquid crystal discharged through the outflow port 323 flows into the connecting pipe 920 through the pipe 990 and the inlet 911 of the spraying unit 900.
當施加電場時,壓電裝置930產生機械應力,藉此以大於20KHz的頻率震動連接管920。When an electric field is applied, the piezoelectric device 930 generates mechanical stress, thereby vibrating the connecting tube 920 at a frequency greater than 20 KHz.
連接管920的震動造成流入連接管920之液晶L震動。如此使得液晶L破成非常小的粒子C。The vibration of the connecting tube 920 causes the liquid crystal L flowing into the connecting tube 920 to vibrate. This causes the liquid crystal L to break into very small particles C.
如圖7所示,這些非常小的液晶粒子透過出口912落在面板區域U。As shown in FIG. 7, these very small liquid crystal particles fall through the outlet 912 in the panel region U.
圖8為顯示噴塗單元所噴塗的液晶落在母基板上界定的四個面板區域各個上之四個區域之示意圖。FIG. 8 is a schematic view showing four regions in which the liquid crystal sprayed by the spray unit falls on each of the four panel regions defined on the mother substrate.
如圖8所示,非常小的液晶粒子C置於四個面板區域U的各個面板區域的四個區域。As shown in FIG. 8, very small liquid crystal particles C are placed in four regions of the respective panel regions of the four panel regions U.
因為非常小的液晶粒子的重量遠小於液晶滴的重量,所以非常小的液晶粒子比液晶滴還不會從面板區域彈開。如此確保非常小的液晶粒子不會落在其他地方,例如密封劑(膠)圖案上。因此,免除補償短缺液晶的需要。再者,因為非常小的液晶粒子落在面板區域的衝擊小得多,所以兩個母基板彼此附接後,不會出現液滴記號於LCD面板。Since the weight of very small liquid crystal particles is much smaller than the weight of liquid crystal droplets, very small liquid crystal particles do not bounce off from the panel region than liquid crystal droplets. This ensures that very small liquid crystal particles do not fall elsewhere, such as on a sealant (glue) pattern. Therefore, the need to compensate for the shortage of liquid crystals is eliminated. Furthermore, since the impact of very small liquid crystal particles falling on the panel region is much smaller, the droplets are not marked on the LCD panel after the two mother substrates are attached to each other.
