The frames of these electronic devices are becoming increasingly narrow and the demands on brightness are increasing. At the same time, the demand for power saving must be satisfied. Display devices and display panels are important members in liquid crystal display devices.
一般に、液晶パネルは両面粘着テープで表示装置の四隅に固定される。然しながら、液晶モジュールの厚さはますます薄くなってきている。これにともない、液晶表示パネルの厚さに対しても過酷な要求が突き付けられている。表示パネルの厚さが薄くなると、表示パネルの側縁を両面粘着テープに接着するため、両面粘着テープの粘着力による液晶表示パネルの損壊が容易に発生する。特に、接着しなおす場合、液晶表示パネルを両面粘着テープから剥離させなければならず、両面粘着テープの粘着性を克服しなければ、液晶表示パネルは容易に損壊する。 Generally, the liquid crystal panel is fixed to the four corners of the display device with a double-sided adhesive tape. However, the thickness of the liquid crystal module is becoming thinner. Accordingly, severe demands are imposed on the thickness of the liquid crystal display panel. When the thickness of the display panel is reduced, the side edges of the display panel are bonded to the double-sided adhesive tape, and therefore the liquid crystal display panel is easily damaged by the adhesive force of the double-sided adhesive tape. In particular, when rebonding, the liquid crystal display panel must be peeled off from the double-sided pressure-sensitive adhesive tape, and the liquid crystal display panel is easily damaged unless the adhesiveness of the double-sided pressure-sensitive adhesive tape is overcome.

この発明における技術プランを詳述するために、具体的な実施例を挙げ、図面を参照して完全に説明する。 In order to elaborate the technical plan in the present invention, a specific example is given and fully described with reference to the drawings.
図１に開示するこの発明の表示装置は、表示パネル１０とバックライトモジュール２０とを含む。表示パネル１０はバックライトモジュール２０上に重ね合わせて設ける。表示パネル１０はフレーム領域１６２を含む、表示装置は両面粘着テープ３０と保護フィルム４０とをさらに含む。保護フィルム４０粘着性がなく、かつ図２に開示するように複数の窓４２を形成する。保護フィルム４０は両面粘着テープ３０の一方の面に貼着する。両面粘着テープ３０の他方の面はバックライトモジュール２０に粘着する。表示パネル１０のフレーム領域１６２は、保護フィルム４０の両面粘着テープ３０に接する側とは反対の側に位置し、窓４２を介して領域内の両面粘着テープ３０とフレーム領域１６２とが接触して表示パネル１０をバックライトモジュール２０に粘着する。 The display device disclosed in FIG. 1 includes a display panel 10 and a backlight module 20. The display panel 10 is provided on the backlight module 20 in an overlapping manner. The display panel 10 includes a frame region 162, and the display device further includes a double-sided adhesive tape 30 and a protective film 40. The protective film 40 has no adhesiveness, and a plurality of windows 42 are formed as disclosed in FIG. The protective film 40 is attached to one surface of the double-sided pressure-sensitive adhesive tape 30. The other surface of the double-sided adhesive tape 30 adheres to the backlight module 20. The frame area 162 of the display panel 10 is located on the opposite side of the protective film 40 from the side in contact with the double-sided adhesive tape 30, and the double-sided adhesive tape 30 in the area and the frame area 162 are in contact with each other through the window 42. The display panel 10 is adhered to the backlight module 20.
この発明は、両面粘着テープ３０と表示パネル１０のフレーム領域１６２との間に保護フィルム４０を設ける。保護フィルム４０には粘着性がないため、フレーム領域１６２と保護フィルム４０との接触は、表示パネル１０のフレーム領域１６２とバックライトモジュール２０との間の粘着強度を低下させることができる。よって、表示パネル１０をバックライトモジュール２０から剥離する過程においてパネルの損壊を最小限に抑制することができる。 In the present invention, a protective film 40 is provided between the double-sided adhesive tape 30 and the frame region 162 of the display panel 10. Since the protective film 40 has no adhesiveness, the contact between the frame region 162 and the protective film 40 can reduce the adhesive strength between the frame region 162 of the display panel 10 and the backlight module 20. Therefore, in the process of peeling the display panel 10 from the backlight module 20, damage to the panel can be suppressed to a minimum.
保護フィルム４０を設けることによって、表示パネル１０のフレーム領域１６２とバックライトモジュール２０との間に隙間がなくなる。このため、隙間が存在することで起きる表示パネル１０内の応力を低下させ、表示パネル１０の表示効果を優れたものとすることができる。 By providing the protective film 40, there is no gap between the frame region 162 of the display panel 10 and the backlight module 20. For this reason, the stress in the display panel 10 which arises when there exists a clearance gap can be reduced, and the display effect of the display panel 10 can be made excellent.
具体的に述べると、表示パネル１０は順に積層して設ける上偏光シート１２と、上層ガラス１４と、下層ガラス１６と、下偏光シート１８とを含む。下層ガラス１６は、外縁部が延伸してフレーム領域１６２を形成する、両面粘着テープ３０は下偏光フィルム１８のフレーム底部に至るまで延伸して、下偏光シート１８がバックライトモジュール２０に粘着する。 Specifically, the display panel 10 includes an upper polarizing sheet 12, an upper glass layer 14, a lower glass layer 16, and a lower polarizing sheet 18 that are sequentially stacked. The lower glass 16 is stretched at the outer edge to form a frame region 162. The double-sided adhesive tape 30 is stretched to reach the bottom of the frame of the lower polarizing film 18, and the lower polarizing sheet 18 adheres to the backlight module 20.
保護フィルム４０の上面は、フレーム領域１６２の底面に接触し、下偏光シート１８の上面が下ガラス層１６に接触する。保護フィルム４０と下偏光シート１８は、それぞれの上面の高さが揃うように設計する。よって、下層ガラス１６の平面度を保証することができ、さらには表示パネル１０の表示効果を保証することができる。 The upper surface of the protective film 40 is in contact with the bottom surface of the frame region 162, and the upper surface of the lower polarizing sheet 18 is in contact with the lower glass layer 16. The protective film 40 and the lower polarizing sheet 18 are designed so that the heights of the upper surfaces thereof are aligned. Therefore, the flatness of the lower layer glass 16 can be guaranteed, and further, the display effect of the display panel 10 can be guaranteed.
フレーム領域１６２の上面にはチップ１５とフレキシブル回路基板１３とを設ける。チップ１５とフレキシブル回路基板１３とを設けることによって表示パネル１０のタッチ機能を実現することができる。保護フィルム４０を設けることによって表示パネル１０を同一平面上に保持することができ、かつ表示パネル１０のフレーム領域１６２とバックライトモジュール２０とを取り付ける場合、隙間なく取り付けることができ、表示パネル１０のフレーム領域１６２の変形を防ぐことができ、このためチップ１５とフレキシブル回路基板１３との間の良好な信号の伝送を保証することができる。さらには表示パネル１０の表示効果を保証することができる。 The chip 15 and the flexible circuit board 13 are provided on the upper surface of the frame region 162. By providing the chip 15 and the flexible circuit board 13, the touch function of the display panel 10 can be realized. By providing the protective film 40, the display panel 10 can be held on the same plane, and when the frame region 162 of the display panel 10 and the backlight module 20 are attached, the display panel 10 can be attached without a gap. The deformation of the frame region 162 can be prevented, so that a good signal transmission between the chip 15 and the flexible circuit board 13 can be ensured. Furthermore, the display effect of the display panel 10 can be guaranteed.
バックライトモジュール２０の具体的な構造は以下に述べるとおりである。即ち、バックライトモジュール２０は、樹脂枠２２と、導光板２４と、光学フィルム２６と、ストリップライト光源２８とを含む。導光板２４は樹脂枠２２が囲繞する空間内に設ける。ストリップライト光源２８は、樹脂枠２２と導光板２４とが隣り合う位置に設ける。光学フィルム２６は導光板２４上に積層して設ける。下偏光シート１８は光学フィルム２６の導光板２４側とは反対の側に設ける。両面粘着テープ３０は樹脂枠２２と、ストリップライト光源２８と、光学フィルム２６の外縁部に粘着する。 The specific structure of the backlight module 20 is as described below. That is, the backlight module 20 includes a resin frame 22, a light guide plate 24, an optical film 26, and a striplight light source 28. The light guide plate 24 is provided in a space surrounded by the resin frame 22. The strip light source 28 is provided at a position where the resin frame 22 and the light guide plate 24 are adjacent to each other. The optical film 26 is provided by being laminated on the light guide plate 24. The lower polarizing sheet 18 is provided on the side opposite to the light guide plate 24 side of the optical film 26. The double-sided adhesive tape 30 adheres to the resin frame 22, the striplight light source 28, and the outer edge of the optical film 26.
ストリップライト光源２８は、ベース座２８２と発光部材２８４とを含む。発光部材２８４はベース座２８２の一方の側に突設し、かつ発光部材２８４は樹脂枠２２と導光板２４との間に延伸する、ベース座２８２の発光部材２８４を設ける側と反対の側の表面は、樹脂枠２２の上面と高さを揃え、両者によって共同で貼着面を形成する。両面粘着テープ３０は該貼着面に粘着する。 The strip light source 28 includes a base seat 282 and a light emitting member 284. The light emitting member 284 protrudes on one side of the base seat 282, and the light emitting member 284 extends between the resin frame 22 and the light guide plate 24, on the side opposite to the side on which the light emitting member 284 of the base seat 282 is provided. The surface is aligned with the top surface of the resin frame 22 and forms a sticking surface together. The double-sided adhesive tape 30 adheres to the sticking surface.
バックライトモジュール２０は、バックプレート２７と反射板２５とを含み、バックプレート２７は導光板２４と樹脂枠２２を支持するために用いる。反射板２５は導光板２４の底面に設ける。他の実施の形態において、反射板２５は反射層を塗布して代替としてよい。 The backlight module 20 includes a back plate 27 and a reflection plate 25, and the back plate 27 is used to support the light guide plate 24 and the resin frame 22. The reflection plate 25 is provided on the bottom surface of the light guide plate 24. In other embodiments, the reflector 25 may be replaced with a reflective layer.
保護フィルム４０は両面粘着テープ３０と一体に構成するか、もしくは分離した構造としてもよい。一帯に構成する場合は、両面粘着テープ３０の製造過程において、両面粘着テープ３０の一方の面の粘着剤でスペーサーを形成する多段粘着形式とする。保護フィルム４０の窓４２の分布構造に類似する。同時に、両面粘着テープ３０の厚さを通常の両面粘着テープ３０より厚くする。このため表示パネル１０とバックライトモジュール２０とを取り付ける場合、隙間なく取り付けることができる。分離した構造にする場合は、図２に開示する粘着性のない保護フィルム４０を単独で制作し、通常の両面粘着テープ３０の表面を保護フィルム４０に粘着する。 The protective film 40 may be configured integrally with the double-sided pressure-sensitive adhesive tape 30 or may have a separated structure. In the case where the belt is configured as a single band, a multi-stage pressure-sensitive adhesive type in which a spacer is formed with the pressure-sensitive adhesive on one surface of the double-sided pressure-sensitive adhesive tape 30 in the manufacturing process of the double-sided pressure-sensitive adhesive tape 30 is adopted. Similar to the distribution structure of the windows 42 of the protective film 40. At the same time, the thickness of the double-sided pressure-sensitive adhesive tape 30 is made thicker than that of the normal double-sided pressure-sensitive adhesive tape 30.
