以薄膜電晶體(TNT)的液晶顯示模組為例，這些液晶顯示模組一般包含一液晶顯示面板及多個驅動晶片。這些驅動晶片設於液晶顯示面板之周緣。驅動晶片輸出電壓使顯示面板中之液晶扭轉，以令液晶顯示面板表現色階及明暗之變化。 Taking a liquid crystal display module of a thin film transistor (TNT) as an example, these liquid crystal display modules generally include a liquid crystal display panel and a plurality of driving chips. These drive chips are disposed on the periphery of the liquid crystal display panel. Driving the output voltage of the wafer causes the liquid crystal in the display panel to be twisted, so that the liquid crystal display panel exhibits a change in color gradation and brightness.
現今將驅動晶片設於液晶顯示面板之常用的方法係透過異方性導電膠(Anisotropic Conductive Film，ACF)、紫外線膠或銀膠將驅動晶片封裝於液晶顯示面板上。然而，在驅動晶片封裝於液晶顯示面板的製程後卻會導致液晶顯示面板發生翹曲而令液晶顯示模組的明暗分佈不均勻。因此，如何改善液晶顯示模組之明暗分佈不均的狀況，將是研發人員所欲求的目標。 Nowadays, a common method of driving a wafer on a liquid crystal display panel is to package a driver wafer on a liquid crystal display panel through an anisotropic conductive film (ACF), an ultraviolet glue or a silver paste. However, after the process of driving the chip package on the liquid crystal display panel, the liquid crystal display panel is warped and the light and dark distribution of the liquid crystal display module is uneven. Therefore, how to improve the uneven distribution of the liquid crystal display module will be the goal of the research and development personnel.
本發明在於提供一種顯示裝置，藉以改善顯示裝置明暗不均的狀況。 The present invention provides a display device for improving the brightness and darkness of a display device.

The optical film set is interposed between the display panel and the light guide plate. The driving chip is disposed on one side of the display panel. The light reducing layer is interposed between the light guide plate and the driving wafer. The dimming layer includes a plurality of dimming bodies. The dimmers extend from a side of the adjacent drive wafer toward a first direction away from the drive wafer.
根據上述本發明所揭露的顯示裝置，在驅動晶片與導光板之間的任意材料上鄰近驅動晶片之區域內印刷減光層，而減光層可降低鄰近於驅動晶片之亮度，進而改善顯示裝置之明暗不均的現象。 According to the display device disclosed in the above invention, the light-reducing layer is printed in an area adjacent to the driving wafer on any material between the driving wafer and the light guiding plate, and the light-reducing layer can reduce the brightness adjacent to the driving wafer, thereby improving the display device.

In other embodiments, the light source module 500 may also be a light emitting diode (Light emitting diode). Diode).
驅動晶片600(Drive IC)設於顯示面板400之一側。詳細來說，驅動晶片600係透過封裝膠封裝於第二玻璃基板420之一側。本實施之封裝膠可以是異方性導電膠(Anisotropic Conductive Film，ACF)、紫外線膠或銀膠，並不以此為限。 A driving chip 600 (Drive IC) is provided on one side of the display panel 400. In detail, the driving chip 600 is encapsulated on one side of the second glass substrate 420 through the encapsulant. The encapsulant of the present embodiment may be an anisotropic conductive film (ACF), an ultraviolet glue or a silver paste, and is not limited thereto.
減光層700設於驅動晶片600與導光板200之間。舉例來說，本實施例之減光層700設於光學膜片組300之擴散片310。減光層700設於擴散片310的方式例如為印刷。此外，驅動晶片600投影至減光層700而具有一投影範圍600’。 The light reduction layer 700 is disposed between the driving wafer 600 and the light guide plate 200. For example, the light-reducing layer 700 of the present embodiment is disposed on the diffusion sheet 310 of the optical film set 300. The mode in which the dimming layer 700 is provided on the diffusion sheet 310 is, for example, printing. In addition, the drive wafer 600 is projected onto the dimming layer 700 to have a projection range 600'.
減光層700包含複數個減光體710。這些減光體710自驅動晶片600之投影範圍600’之鄰近可視區域450一側朝遠離驅動晶片600之投影範圍600’的一第一方向(沿箭頭a所指示的方向)延伸。換言之，減光體710係自驅動晶片600之投影範圍600’之一側延伸至可視區域450內。 The light reduction layer 700 includes a plurality of light reduction bodies 710. These dimmers 710 extend from a side of the adjacent viewing area 450 of the projection range 600' of the drive wafer 600 toward a first direction (in the direction indicated by arrow a) away from the projection range 600' of the drive wafer 600. In other words, the light reducing body 710 extends from one side of the projection range 600' of the driving wafer 600 into the visible region 450.
如第2圖所示，在本實施例中，這些減光體710係以驅動晶片600之投影範圍600’之一側邊的中點為分佈中心且呈放射線狀分佈。這些減光體710之間距沿第一方向(沿箭頭a所指示的方向)逐漸增加。在此處所指的間距d為各相鄰之減光體710的邊緣所保持的距離。這些減光體710之直徑介於0.05毫米至0.45毫米之間，且減光體710的直徑沿第一方向(沿箭頭a所指示的方向)逐減變小，以令這些減光體710之面積沿第一方向(沿箭頭a所指示的方向)逐漸縮小。 As shown in Fig. 2, in the present embodiment, these light-reducing bodies 710 are distributed in a radial manner with the midpoint of one side of the projection range 600' of the driving wafer 600 as a distribution center. The distance between these light-reducing bodies 710 gradually increases in the first direction (in the direction indicated by the arrow a). The spacing d referred to herein is the distance maintained by the edges of adjacent dimmers 710. The diameters of the light-reducing bodies 710 are between 0.05 mm and 0.45 mm, and the diameter of the light-reducing body 710 is reduced in the first direction (in the direction indicated by the arrow a) to make the light-reducing bodies 710 The area gradually decreases in the first direction (in the direction indicated by the arrow a).
本實施例之減光體710的顏色為白色，透光率為80百分比(%)，但並不以此為限，減光體710也可以是其他顏色，如灰色、藍色或黃色。此外，減光體710的透光率可以是小於100百分比(%)的任意值。也就是說減光體710只要不是完全透明、無遮光效果即可。舉例來說，減光體710的透光率例如介於70百分比(%)至90百分比(%)之間。 The light-reducing body 710 of the present embodiment has a white color and a light transmittance of 80% (%), but is not limited thereto. The light-reducing body 710 may also be other colors such as gray, blue or yellow. Further, the light transmittance of the light reducing body 710 may be any value less than 100% (%). That is to say, the light-reducing body 710 is not completely transparent and has no light-shielding effect. For example, the light transmittance of the light reducing body 710 is, for example, between 70% (%) and 90% (%).
由於顯示裝置10在驅動晶片600設於第二玻璃基板420的封裝過程後會令第二玻璃基板420產生撓曲，進而導致顯示裝置10於鄰近驅動晶片600的位置處產生明暗不均 的現象(Chip on Glass MURA，COG MURA)，且越靠近驅動晶片600明暗不均的現象則越明顯。因此，本實施例在擴散片310鄰近驅動晶片600的位置處印刷有多個面積較大的減光體710，而減光體710的面積隨著與驅動晶片600之間的距離增加而逐漸變小。如此一來，可透過減光體710的遮光及減光效果，來改善顯示裝置10之明暗不均的現象。 The display device 10 may cause the second glass substrate 420 to flex after the packaging process of the driving wafer 600 is disposed on the second glass substrate 420, thereby causing unevenness of the display device 10 at a position adjacent to the driving wafer 600. The phenomenon (Chip on Glass MURA, COG MURA), and the closer to the driver chip 600, the more obvious the phenomenon of uneven brightness. Therefore, in the present embodiment, a plurality of large-area light-reducing bodies 710 are printed at a position where the diffusion sheet 310 is adjacent to the driving wafer 600, and the area of the light-reducing body 710 gradually changes as the distance from the driving wafer 600 increases. small. In this way, the phenomenon of light and dark unevenness of the display device 10 can be improved by the light blocking and dimming effects of the light reducing body 710.
上述實施例之這些減光體710係以驅動晶片600之投影範圍600’之一側邊的中點為分佈中心且呈放射線狀分佈，但並不以此為限。實務上，可先偵測顯示裝置10明暗不均現象的分佈位置，再依據產生明暗不均現象處決定這些減光體710的分佈位置。請參閱第3圖，第3圖為根據本發明第二實施例的顯示裝置的剖面示意圖。本實施例與上述第1圖之實施例相似，故僅針對相異處進行說明。 The light-reducing bodies 710 of the above embodiment are distributed at a midpoint of one side of the projection range 600' of the driving wafer 600, and are distributed in a radial manner, but are not limited thereto. In practice, the distribution position of the display device 10 may be detected first, and then the distribution position of the light-reducing bodies 710 may be determined according to the phenomenon of uneven brightness. Please refer to FIG. 3, which is a cross-sectional view of a display device according to a second embodiment of the present invention. This embodiment is similar to the embodiment of Fig. 1 described above, and therefore only the differences will be described.
在本實施例中，這些減光體710係以驅動晶片600之投影範圍600’之鄰近可視區域450之一側邊的相對兩端為分佈中心且呈放射線狀分佈。本實施例之減光體710的分佈係主要適用於顯示裝置10之明暗分佈現象出現在驅動晶片600的左右兩側的情況。但若顯示裝置10出現明暗不均現象是在驅動晶片600之某一側時，也可以針對出現明暗不均現象的位置印刷減光體710。 In the present embodiment, the light-reducing bodies 710 are distributed at the opposite ends of one side of the adjacent visible region 450 of the projection range 600' of the driving wafer 600 and are radially distributed. The distribution of the light-reducing body 710 of the present embodiment is mainly applicable to the case where the light-dark distribution phenomenon of the display device 10 appears on the left and right sides of the driving wafer 600. However, if the display device 10 exhibits a phenomenon of unevenness in light and darkness on one side of the driving wafer 600, the light-reducing body 710 may be printed at a position where the unevenness of light and darkness occurs.
上述實施例之減光層700係設於擴散片310，但並不以此為限，在其他實施例中，減光層700也可以設於驅 動晶片600與導光板200之間的任意材料上。以下將任舉兩個例子。請參閱第4圖與第5圖，第4圖為根據本發明第三實施例的顯示裝置的剖面示意圖，第5圖為根據本發明第四實施例的顯示裝置的剖面示意圖。如第4圖所示，本實施之減光層700係設於導光板200與驅動晶片600之間的第二偏光片440。也可以如第5圖所示，本實施例之減光層700係設於導光板200與驅動晶片600之間的第二玻璃基板420。但並不以此為限。 The dimming layer 700 of the above embodiment is disposed on the diffusion sheet 310, but is not limited thereto. In other embodiments, the dimming layer 700 may also be disposed on the flooding layer 700. Any material between the movable wafer 600 and the light guide plate 200. Below are two examples. 4 and 5, FIG. 4 is a schematic cross-sectional view of a display device according to a third embodiment of the present invention, and FIG. 5 is a cross-sectional view of the display device according to a fourth embodiment of the present invention. As shown in FIG. 4, the light-reducing layer 700 of the present embodiment is disposed on the second polarizer 440 between the light guide plate 200 and the driving wafer 600. As shown in FIG. 5, the light-reducing layer 700 of the present embodiment is disposed on the second glass substrate 420 between the light guide plate 200 and the driving wafer 600. But it is not limited to this.
根據上述本發明所揭露的顯示裝置，在驅動晶片與導光板之間的任意材料上鄰近驅動晶片之區域內印刷減光層，而減光層可降低鄰近於驅動晶片之亮度，進而改善顯示裝置之明暗不均的現象。 According to the display device disclosed in the above invention, the light-reducing layer is printed in an area adjacent to the driving wafer on any material between the driving wafer and the light guiding plate, and the light-reducing layer can reduce the brightness adjacent to the driving wafer, thereby improving the display device. The phenomenon of uneven brightness.
此外，減光體之間距隨著遠離驅動晶片而逐漸變大以及減光體之面積隨著遠離驅動晶片而逐漸變小，使得較鄰近驅動晶片之各減光體所降低的光線通過量大於較遠離驅動晶片之各減光體所降低的光線通過量，以改善顯示裝置之明暗不均的現象。 In addition, the distance between the light-reducing bodies is gradually increased as being away from the driving wafer, and the area of the light-reducing body is gradually smaller as being away from the driving wafer, so that the light passing amount of the light-reducing bodies closer to the driving wafer is reduced. The amount of light passing away from each of the light-reducing bodies of the driving chip is reduced to improve the unevenness of the display device.
雖然本發明的實施例揭露如上所述，然並非用以限定本發明，任何熟習相關技藝者，在不脫離本發明的精神和範圍內，舉凡依本發明申請範圍所述的形狀、構造、特徵及數量當可做些許的變更，因此本發明的專利保護範圍須視本說明書所附的申請專利範圍所界定者為準。 Although the embodiments of the present invention are disclosed above, it is not intended to limit the present invention, and those skilled in the art, regardless of the spirit and scope of the present invention, the shapes, configurations, and features described in the scope of the present application.
