Description

本発明は、液晶表示パネル等の表示パネルにおいて、表示領域の周縁を覆うために形成されているブラックマスクに関するものである。
The present invention relates to a black mask formed to cover the periphery of a display area in a display panel such as a liquid crystal display panel.

液晶表示パネル１００の一般的な構造は、図５に示したように、主要な構成としては、バックライトとしての光を供給するバックライト部１０１と、電極に挟まれて実際の表示を行う液晶部１０２と、前記液晶部１０２の表面に配設された透明なガラス１０３と、前記ガラス１０３の周縁に形成されている遮光性のブラックマスク１０４と、前記ガラス１０３と前記ブラックマスク１０４を覆って配設されている透明な保護板１０５とが積層された構造となっている。
前記ブラックマスク１０４は、液晶表示パネル１００の表面の前記ガラス１０３の周縁部分を被覆する程度の大きさに形成されている。また、前記ブラックマスク１０４の背面には例えば接着剤が塗布されており、前記ガラス１０３の表面に固着させることによって、前記液晶表示パネル１００のガラス１０３に固着されるようになっている。
前記ブラックマスク１０４と前記ガラス１０３の表面には、さらに前記保護板１０５が接着剤等で固着されている。 As shown in FIG. 5, the general structure of the liquid crystal display panel 100 includes a backlight unit 101 that supplies light as a backlight and a liquid crystal that is sandwiched between electrodes and that performs actual display. Part 102, transparent glass 103 disposed on the surface of liquid crystal part 102, light-shielding black mask 104 formed on the periphery of glass 103, covering glass 103 and black mask 104 A transparent protective plate 105 provided is laminated.
The black mask 104 is formed to a size that covers the peripheral portion of the glass 103 on the surface of the liquid crystal display panel 100. Further, for example, an adhesive is applied to the back surface of the black mask 104 and is fixed to the glass 103 of the liquid crystal display panel 100 by being fixed to the surface of the glass 103.
The protective plate 105 is further fixed to the surface of the black mask 104 and the glass 103 with an adhesive or the like.

前記液晶表示パネル１００の側面断面図を図６に示した。
図６に示したように、
前記ブラックマスク１０４は前記ガラス１０３の表面の周縁に固着されており、前記ブラックマスク１０４と前記ガラス１０３の表面には、さらに前記保護板１０５が積層して固着されて、表面パネル１１０が形成されている。
このような構造の表面パネル１１０が液晶部１０２に積層されている。 A side sectional view of the liquid crystal display panel 100 is shown in FIG.
As shown in FIG.
The black mask 104 is fixed to the peripheral edge of the surface of the glass 103, and the protective plate 105 is further laminated and fixed on the surface of the black mask 104 and the glass 103 to form a surface panel 110. ing.
The front panel 110 having such a structure is stacked on the liquid crystal unit 102.

ここで、前記ブラックマスク１０４は若干の厚みをもっているため、前記ブラックマスク１０４の表面と、前記ガラス１０３の表面との間には若干の段差Ｓが生じている。この段差Ｓによって前記ガラス１０３と前記保護板１０５との間には隙間が形成されている。
前記ガラス１０３と前記保護板１０５とが何れも十分な厚みがある場合には、前記隙間は存続するが、例えば前記保護板１０５が薄いと撓みが発生して歪むことになり、表側から見たときに視覚的な歪みが生じるという問題がある。
また、前記ガラス１０３が薄い場合には、ガラス１０３が変形してしまい、表側から見たときに視覚的な歪みが生じるという問題がある。
なお、ブラックマスクが開示されている一般的な参考文献として特許文献１を挙げた。 Here, since the black mask 104 has a slight thickness, there is a slight step S between the surface of the black mask 104 and the surface of the glass 103. A gap is formed between the glass 103 and the protective plate 105 by the step S.
When both the glass 103 and the protective plate 105 have a sufficient thickness, the gap continues, but for example, if the protective plate 105 is thin, the glass plate 103 and the protective plate 105 are bent and distorted, as viewed from the front side. There is a problem that visual distortion sometimes occurs.
Further, when the glass 103 is thin, the glass 103 is deformed, and there is a problem that visual distortion occurs when viewed from the front side.
Patent Document 1 is cited as a general reference document that discloses a black mask.

特開２００３−３１５７９３号公報JP 2003-315793 A

従来は、ガラス１０３も保護板１０５も十分な厚みを持たせて変形しないようにしていたが、近年の薄型への要求に応じて、ガラス１０３もしくは保護板１０５を薄くすると、強度が低下して変形しやすくなるという問題が避けられなくなっていた。
前記ブラックマスクの厚さを極力薄くすると、ガラス１０３もしくは保護板１０５を薄くしてもその変形による視覚的な問題が少なくなるが、今度は、薄いブラックマスクでは遮光性が不十分になるという別の問題が生じる。例えば、シルク印刷では厚くなりすぎるので、オフセット印刷によって薄くすると、遮光性が不十分で光が漏れる問題や、ピンホール等の発生等の問題が発生する。
また、表面の透明な保護板１０５に代えて可撓性のある薄い透明な保護シートを積層する場合には、保護シートが前記段差に沿って変形してガラス１０３の表面に密着することになり、この場合も、保護シートが段差に沿って変形することによって、視覚的な歪みが生じるという問題が発生する。
このような視覚的な歪みがあると前記液晶表示パネル１００の商品としての価値を損なうことになる。
前記ブラックマスク１０４を、遮光性のシート材を配設して形成しても、遮光性の塗膜で形成しても、厚みの違いによって歪みの多少はあるが、前記段差Ｓを消すことはできなかった。 Conventionally, neither the glass 103 nor the protective plate 105 has a sufficient thickness so as not to be deformed. However, in response to the recent demand for thinness, when the glass 103 or the protective plate 105 is thinned, the strength is lowered. The problem of easy deformation was inevitable.
If the thickness of the black mask is reduced as much as possible, even if the glass 103 or the protective plate 105 is thinned, the visual problem due to the deformation is reduced, but this time, the thin black mask has insufficient light shielding properties. Problem arises. For example, since it is too thick in silk printing, if it is thinned by offset printing, problems such as insufficient light shielding and light leakage and occurrence of pinholes occur.
In addition, when a flexible thin transparent protective sheet is laminated instead of the transparent protective plate 105 on the surface, the protective sheet deforms along the step and adheres to the surface of the glass 103. In this case as well, there arises a problem that visual distortion occurs due to the deformation of the protective sheet along the step.
Such visual distortion impairs the value of the liquid crystal display panel 100 as a product.
Whether the black mask 104 is formed by arranging a light-shielding sheet material or a light-shielding coating film, there is some distortion due to the difference in thickness, but the step S is erased. could not.

図５に示したような、前記液晶表示パネル１００の商品としての価値を損なっている前記段差Ｓを無くすことによって、液晶表示パネルの商品としての価値を高めることを目的として、本発明はなされたものである。
The present invention has been made for the purpose of increasing the value of the liquid crystal display panel as a product by eliminating the step S that impairs the value of the liquid crystal display panel 100 as shown in FIG. Is.

以下においては、本発明に係るブラックマスクを図面を参照して、その概要を説明する。
図１は、前記ブラックマスクに用いる透明パネルの要部の断面図を示したものであり、透明パネル１の表面側の周縁に、凹部２が形成されている。
前記透明パネル１は、液晶表示パネルの表面に配設された液晶保護用のガラスであり、その表面にはさらに透明な保護シート、もしくはガラス、もしくはアクリル等の透明樹脂製の板が積層されるようになっている。
前記透明パネル１の周縁に形成された凹部２は、前記液晶表示パネルの表示領域の周囲に形成されており、前記凹部２の幅は前記液晶表示パネルの周縁の不要領域をカバーする広さに設定されている。前記凹部２の深さはバックライトの光を遮光するに十分な遮光材の厚さに設定されている。 The outline of the black mask according to the present invention will be described below with reference to the drawings.
FIG. 1 shows a cross-sectional view of a main part of a transparent panel used for the black mask, and a recess 2 is formed on the periphery of the surface side of the transparent panel 1.
The transparent panel 1 is a glass for protecting a liquid crystal disposed on the surface of a liquid crystal display panel, and a transparent protective sheet, or a plate made of a transparent resin such as glass or acrylic is laminated on the surface. It is like that.
The recess 2 formed on the periphery of the transparent panel 1 is formed around the display area of the liquid crystal display panel, and the width of the recess 2 is wide enough to cover an unnecessary area on the periphery of the liquid crystal display panel. Is set. The depth of the concave portion 2 is set to a thickness of a light shielding material sufficient to shield light from the backlight.

図２の（Ａ）に示したように、前記凹部２には、バックライトの光を遮光するための遮光材３が配設されており、前記遮光材３の厚さは、前記凹部２の深さと同じに設定されているので、前記透明パネル１の表面と、前記遮光材３の表面とは、段差の無い連続したほぼ面一の同一平面状になっている。   As shown in FIG. 2A, a light shielding material 3 for shielding light from a backlight is disposed in the concave portion 2, and the thickness of the light shielding material 3 is the same as that of the concave portion 2. Since it is set to be the same as the depth, the surface of the transparent panel 1 and the surface of the light shielding material 3 are continuous and substantially flush and have the same plane.

図２の（Ｂ）に示したように、以上のように構成した透明パネル１と遮光材３に保護シート４を積層して、表面パネル５は構成されている。
As shown in FIG. 2B, the front panel 5 is configured by laminating a protective sheet 4 on the transparent panel 1 and the light shielding material 3 configured as described above.

以下においては、本発明の実施例１にかかる表示パネルのブラックマスク形成方法とその構造を形成する手順について図１、２を参照して説明する。
先ず、図１に示したように、ガラス等の透明パネル１の表面側の周縁に、凹部２を形成する。前記凹部２の形成方法としては種々の方法が可能であるが、例えば、加工用の刃などを用いて、板状の透明パネル素材の表面側の周縁を浅く帯状に物理的に切削して前記凹部２を形成してもよく、または、化学薬品を用いて板状の透明パネル素材の表面側の周縁を浅く帯状に化学的に溶解等させることによって前記凹部２を形成してもよく、前記透明パネル１を板状に成型する際に、前記凹部２を一体成型してもよい。または、以上に述べた物理的加工方法、化学的加工方法、または、一体成型方法を組み合わせて凹部２を形成してもよい。 Hereinafter, a black mask forming method for a display panel and a procedure for forming the structure according to the first embodiment of the present invention will be described with reference to FIGS.
First, as shown in FIG. 1, the recessed part 2 is formed in the periphery of the surface side of transparent panels 1, such as glass. Various methods can be used as the method of forming the concave portion 2. For example, the peripheral edge on the surface side of the plate-like transparent panel material is physically cut into a shallow band shape by using a processing blade or the like. The concave portion 2 may be formed, or the concave portion 2 may be formed by chemically dissolving the peripheral edge on the surface side of the plate-like transparent panel material in a shallow band shape using a chemical, When the transparent panel 1 is molded into a plate shape, the concave portion 2 may be integrally molded. Alternatively, the concave portion 2 may be formed by combining the physical processing method, the chemical processing method, or the integral molding method described above.

つぎに、図２の（Ａ）に示したように、前記凹部２に遮光材３を配設する。
前記凹部２に遮光材３を配設する方法としては、種々の方法が可能であるが、例えば、遮光性塗料を前記凹部２に塗布してもよく、または、遮光性シートを接着剤等を用いて前記凹部２に貼付してもよい。
遮光性塗料を前記凹部２に塗布する場合には、一旦塗布した後に、塗膜の表面と透明パネルの表面との段差が内容に表面を均す必要がある。また、前記凹部２以外の表面にも塗料が付着する場合があるので、余分な塗料は除去する必要がある。
遮光性シートを貼付する場合には、前記凹部２の幅に一致したシートを貼付する作業が必要となる。 Next, as shown in FIG. 2A, a light shielding material 3 is disposed in the recess 2.
Various methods can be used as the method for disposing the light shielding material 3 in the recess 2. For example, a light shielding paint may be applied to the recess 2, or the light shielding sheet may be coated with an adhesive or the like. You may stick to the said recessed part 2 using.
When the light-shielding paint is applied to the concave portion 2, it is necessary that the level difference between the surface of the coating film and the surface of the transparent panel is leveled after the application. In addition, since paint may adhere to the surface other than the concave portion 2, it is necessary to remove excess paint.
When sticking a light-shielding sheet, it is necessary to stick a sheet that matches the width of the recess 2.

つぎに、図２の（Ｂ）に示したように、前記透明パネル１の表面と、前記凹部２に配設された前記遮光材３の表面とを、透明な保護シート４で覆う。前記保護シート４は、透明性の高い接着剤等を用いて前記透明パネル１の表面と前記遮光材３の表面に貼付するとよい。
このようにして、前記遮光材３によってブラックマスクが形成された表面パネル５が得られるのである。
この表面パネル５を、図３に示したように、バックライトとしての光を供給するバックライト部１１と、電極に挟まれて実際の表示を行う液晶部１２とに積層して固着することによって、液晶表示パネル１０を形成するのである。
前記遮光材３の表面と前記透明パネル１の表面とがほぼ面一になって、同一平面状になっているので、このように形成した液晶表示パネル１０には従来例のような段差Ｓもしくは隙間が存在せず、保護シート４や透明パネル１が変形して歪むことを防止でき、視覚的な問題を改善できる。
なお、前記バックライト部１１の光源からの光を均一に拡散するための拡散手段、偏光手段、およびフィルタ等などはその説明を省略した。また、前記遮光材３の厚さは必要に応じて適宜設定することができる。
Next, as shown in FIG. 2B, the surface of the transparent panel 1 and the surface of the light shielding material 3 disposed in the recess 2 are covered with a transparent protective sheet 4. The protective sheet 4 may be attached to the surface of the transparent panel 1 and the surface of the light shielding material 3 using a highly transparent adhesive or the like.
In this way, the front panel 5 in which the black mask is formed by the light shielding material 3 is obtained.
As shown in FIG. 3, the front panel 5 is laminated and fixed to a backlight unit 11 that supplies light as a backlight and a liquid crystal unit 12 that is sandwiched between electrodes and performs actual display. The liquid crystal display panel 10 is formed.
Since the surface of the light shielding material 3 and the surface of the transparent panel 1 are substantially flush and coplanar, the liquid crystal display panel 10 thus formed has a step S or There are no gaps, the protective sheet 4 and the transparent panel 1 can be prevented from being deformed and distorted, and visual problems can be improved.
The description of the diffusing means, the polarizing means, the filter, etc. for uniformly diffusing the light from the light source of the backlight unit 11 is omitted. Further, the thickness of the light shielding material 3 can be appropriately set as necessary.

実施例１では、透明パネル１の縁に凹部３を形成したが、図４の（Ａ）に示した実施例２のように、透明パネル１Ａの縁から僅かに離した内側に凹部を形成して遮光材３Ａによるブラックマスクを形成して、保護シート４Ａを積層してもよい。この場合には、透明パネルの縁は別途設けるケースカバー等で覆うとよい。   In Example 1, the recessed part 3 was formed in the edge of the transparent panel 1, However, A recessed part was formed in the inner side slightly separated from the edge of the transparent panel 1A like Example 2 shown to (A) of FIG. Alternatively, the protective sheet 4A may be laminated by forming a black mask using the light shielding material 3A. In this case, the edge of the transparent panel may be covered with a case cover or the like provided separately.

図４の（Ｂ）に示した実施例３のように、遮光材３Ｂ凹部の縁は垂直ではなく傾斜させてもよい。この場合には遮光材３Ｂと透明パネル１Ｂの凹部との馴染みがよい。   As in the third embodiment shown in FIG. 4B, the edge of the light shielding material 3B recess may be inclined instead of vertical. In this case, the familiarity between the light shielding material 3B and the concave portion of the transparent panel 1B is good.

図４の（Ｃ）に示した実施例４のように、透明パネル１Ｃではなく、保護シート４Ｃ側に凹部を形成して遮光材３Ｃによるブラックマスクを形成してもよい。この場合には保護シートの厚みを厚めにするとよい。   As in Example 4 shown in FIG. 4C, a black mask made of the light shielding material 3C may be formed by forming a recess on the protective sheet 4C side instead of the transparent panel 1C. In this case, the thickness of the protective sheet is preferably increased.

図４の（Ｄ）に示した実施例５のように、透明パネル１Ｄと保護シート４Ｄの両方に凹部を形成して、両方の凹部に遮光材３Ｄを配置してブラックマスクを形成してもよい。この場合には、遮光材の厚さを十分な厚さにして十分な遮光性を得ることができる。
As in Example 5 shown in FIG. 4D, a concave portion is formed in both the transparent panel 1D and the protective sheet 4D, and a black mask is formed by arranging the light shielding material 3D in both concave portions. Good. In this case, a sufficient light shielding property can be obtained by setting the thickness of the light shielding material to a sufficient thickness.

本発明によるブラックマスクは、パソコンのディスプレイ装置、テレビ、または携帯電話機等の液晶表示パネルに限らず、種々の液晶表示パネルに採用することができる。
さらには、液晶表示パネルに限らず、背面に光源を備えた種々の表示装置において、その縁の不要部分を隠すためのブラックマスクに広く採用することができる。
The black mask according to the present invention is not limited to a liquid crystal display panel such as a display device of a personal computer, a television, or a mobile phone, but can be used in various liquid crystal display panels.
Furthermore, the present invention is not limited to the liquid crystal display panel, and can be widely used as a black mask for hiding unnecessary portions at the edges in various display devices having a light source on the back surface.
