Description
本發明涉及一種液晶監視器面板。 The present invention relates to a liquid crystal monitor panel.
請參考圖1及圖2，目前的液晶監視器面板10包括一有效顯示區域(Active Area)12及位於該有效顯示區域12下方用於驅動該有效顯示區域12工作的一驅動晶片14，該驅動晶片14透過走線與該有效顯示區域12四周上的訊號引腳相連，以實現驅動訊號的輸入，該驅動晶片14與該有效顯示區域12之間的佈線區域16大致呈一梯形，由於位於該驅動晶片14中心處的走線162的數量最多，而愈靠近有效顯示區域12兩側則走線162的數量愈少，即由a-d區間走線162的數量逐漸減小(圖2僅為示意圖，實際的走線數量很多)，又因為該佈線區域16中每條走線162的線寬均相同，故該佈線區域16的整體寬度從該驅動晶片14的中心處到該有效顯示區域12的兩側逐漸減小。 Referring to FIG. 1 and FIG. 2, the current liquid crystal monitor panel 10 includes an active display area (Active Area) 12 and a driving chip 14 located below the effective display area 12 for driving the effective display area 12 for driving. The chip 14 is connected to the signal pin on the periphery of the effective display area 12 through a trace to realize input of a driving signal. The wiring area 16 between the driving chip 14 and the effective display area 12 is substantially trapezoidal. The number of traces 162 at the center of the drive wafer 14 is the largest, and the closer to the sides of the effective display region 12, the fewer the number of traces 162, that is, the number of traces 162 from the ad interval is gradually reduced (Fig. 2 is only a schematic view, The actual number of traces is large, and since the line width of each of the traces 162 in the wiring region 16 is the same, the overall width of the wiring region 16 is from the center of the drive wafer 14 to the two of the effective display regions 12. The side gradually decreases.
由於佈線區域16的整體寬度具有此種逐漸減小的佈線結構，故導致該佈線區域16上的阻抗值也會有較大差異，例如最小阻抗值可能為0.1歐姆，而最大阻抗值則可能達到2053.2歐姆，差值為2053.1歐姆，這種較大的阻抗值差異會影響掃描線(Gate Line)和資料線(Data Line)上傳輸的訊號品質，且液晶監視器愈大，對訊號品質的影響就 愈明顯。 Since the overall width of the wiring region 16 has such a gradually decreasing wiring structure, the impedance value on the wiring region 16 is also greatly different. For example, the minimum impedance value may be 0.1 ohm, and the maximum impedance value may be reached. 2053.2 ohms, the difference is 2053.1 ohms. This large difference in impedance value affects the quality of the signal transmitted on the Gate Line and the Data Line, and the larger the LCD monitor, the effect on the signal quality. on The more obvious.
鑒於上述內容，有必要提供一種可有效降低阻抗值差異的液晶監視器面板。 In view of the above, it is necessary to provide a liquid crystal monitor panel which can effectively reduce the difference in impedance values.
一種液晶監視器面板，包括一有效顯示區域及位於該有效顯示區域下方用於驅動該有效顯示區域工作的一驅動晶片，該驅動晶片透過走線與該有效顯示區域四周上的訊號引腳相連，以實現驅動訊號的輸入，該有效顯示區域與該驅動晶片的佈線區域在位於該驅動晶片中心處至該有效顯示區域兩側的走線數量逐漸減少，且該佈線區域中每條走線的線寬從該驅動晶片中心處向該有效顯示區域的兩側逐漸增大。 A liquid crystal monitor panel includes an effective display area and a driving chip located under the effective display area for driving the effective display area. The driving chip is connected to a signal pin on the periphery of the effective display area through a trace. In order to realize the input of the driving signal, the number of the wirings of the effective display area and the wiring area of the driving wafer at the center of the driving wafer to both sides of the effective display area is gradually reduced, and the line of each of the routing areas in the wiring area The width gradually increases from the center of the drive wafer to both sides of the effective display area.
上述液晶監視器面板將該佈線區域上的每條走線均設計成了逐漸加寬的樣式，從而使整個佈線區域的寬度整體上基本保持不變或減小的程度很小，故可最大程度地減小走線上阻抗值的差異，從而極大地提高了傳輸的訊號品質。 The liquid crystal monitor panel is designed to gradually widen each of the traces on the wiring area, so that the width of the entire wiring area is substantially constant or reduced as a whole, so that the maximum degree is The ground reduces the difference in impedance values on the traces, thereby greatly improving the signal quality of the transmission.
請參照圖3及圖4，本發明液晶監視器面板100的較佳實施方式包括一有效顯示區域120及位於該有效顯示區域120下方用於驅動該有效顯示區域120工作的一驅動晶片140，該驅動晶片140透過走線與該有效顯示區域120四周上的訊號引腳相連，以實現驅動訊號的輸入。 Referring to FIG. 3 and FIG. 4, a preferred embodiment of the liquid crystal monitor panel 100 of the present invention includes an effective display area 120 and a driving wafer 140 located below the effective display area 120 for driving the effective display area 120. The driving chip 140 is connected to the signal pin on the periphery of the effective display area 120 through the trace to realize the input of the driving signal.
該驅動晶片140與該有效顯示區域120之間的佈線區域160大致呈一梯形，位於該驅動晶片140中心處的走線164的數量最多，愈靠近有效顯示區域120兩側則走線164的數量愈少，即由A-D區間走線164的數量逐漸減小(圖4僅為示意圖，實際的走線數量很多)，該佈線區域160中每條走線164的線寬從該驅動晶片140中心處向該有效顯示區域120的兩側逐漸增大，即由A-D區間每條走線164的線寬逐漸增大，以使該佈線區域160的整體寬度從該驅動晶片140的中心處到該有效顯示區域120的兩側基本保持大致不變或減小的程度很小，僅尾部區域靠近D點的一小短距離逐漸變窄(這是由於走線164數量很少的緣故)。例如，在有85條走線的位置處的每條走線164的寬度為10.43mil，在有82條走線的位置處的每條走線164的寬度為10.66mil，即有85條走線的整體寬度與82條走線的整體寬度差不多，具體可根據走線的數量加以設計。 The wiring area 160 between the driving chip 140 and the effective display area 120 is substantially trapezoidal, and the number of the routing lines 164 at the center of the driving wafer 140 is the largest, and the number of the routing lines 164 is closer to the two sides of the effective display area 120. The less, that is, the number of traces 164 in the AD interval is gradually reduced (FIG. 4 is only a schematic diagram, and the actual number of traces is large), and the line width of each trace 164 in the wiring region 160 is from the center of the drive wafer 140. Gradually increasing to both sides of the effective display area 120, that is, the line width of each of the traces 164 of the AD section is gradually increased, so that the overall width of the wiring area 160 is from the center of the driving wafer 140 to the effective display. The sides of the region 120 remain substantially unchanged or reduced to a lesser extent, and only a small short distance of the tail region near point D gradually narrows (this is due to the small number of traces 164). For example, the width of each trace 164 at a location with 85 traces is 10.43 mils, and the width of each trace 164 at a location with 82 traces is 10.66 mils, ie 85 traces The overall width is similar to the overall width of the 82 traces, which can be designed according to the number of traces.
本發明將該佈線區域160上的每條走線164均設計成了逐漸加寬的樣式，從而使整個佈線區域160的寬度整體上基本保持不變或減小的程度很小，故可最大程度地減小走線上阻抗值的差異，從而極大地提高了傳輸的訊號品質。 According to the present invention, each of the traces 164 on the wiring region 160 is designed to be gradually widened, so that the width of the entire wiring region 160 is substantially constant or reduced as a whole, so that the maximum extent is The ground reduces the difference in impedance values on the traces, thereby greatly improving the signal quality of the transmission.
