Definitions
- the present invention relates to an on-vehicle display device.
- Patent Document 1 describes a transparent surface material with an adhesive layer having an adhesive layer formed on the surface.
- a vehicle-mounted display device such as a car navigation device is mounted on a vehicle such as an automobile.
- the in-vehicle display device include a standing type standing outside the dashboard and an embedded type embedded in the dashboard.
- a transparent protective member such as a film is used from the viewpoint of protecting the display panel, but in recent years, from the viewpoint of texture, the use of a glass protective member (cover glass) instead of a film has been used. It is desired.
- laminated glass tends to be thick, and design problems are likely to occur, and the use of tempered glass is required because of its high cost.
- the in-vehicle display device cover glass is required to have excellent impact resistance so that it does not break even if a passenger's head hits when a vehicle collision accident occurs.
- the impact caused by the collision accident is much higher than the energy assumed in a stationary display device such as a liquid crystal television, for example. Therefore, high impact resistance is required for the cover glass.
- the present invention has been made in view of the above points, and an object thereof is to provide an on-vehicle display device having excellent impact resistance of a cover glass.
- an in-vehicle display device is an in-vehicle display device disposed on an interior member of a vehicle, and includes a display panel, a cover glass that covers the display panel, and a housing that houses the display panel.
- the cover glass has a plate thickness of 0.5 to 2.5 mm, a compressive stress layer thickness of 10 ⁇ m or more, and a surface compressive stress of the compressive stress layer.
- FIG. 1 is a schematic cross-sectional view showing a cover glass with an adhesive layer.
- FIG. 2 is a schematic cross-sectional view showing the in-vehicle display device.
- FIG. 3 is a schematic cross-sectional view showing a modification of the in-vehicle display device.
- FIG. 4 is a perspective view showing a test body.
- FIG. 5 is a cross-sectional view taken along line AA in FIG.
- FIG. 6 is a plan view showing the specimen.
- FIG. 7 is a perspective view showing a modification of the fixing portion.
- FIG. 8 is a plan view showing a modification of the specimen.
- FIG. 9 is a graph illustrating an example of a simulation result.
- FIG. 10 is a plan view showing a test piece for a tensile test.
- FIG. 11 is a diagram showing the strain energy density U.
- FIG. 12 is a graph plotting the impact resistance evaluation results.
- the vehicle-mounted display apparatus of this embodiment is demonstrated.
- a method for manufacturing an in-vehicle display device an embodiment in which a cover glass with an adhesive layer is manufactured and bonded to a display panel is shown as an example.
- the method for manufacturing an in-vehicle display device is not limited thereto. Absent.
- the cover glass and the display panel may be bonded via an OCA (Optically Clear Adhesive) film or the like.
- FIG. 1 is a schematic cross-sectional view showing a cover glass with an adhesive layer.
- a cover glass 10 with an adhesive layer shown in FIG. 1 includes a transparent cover glass 12, an adhesive layer 14, a protective film 16, and a light shielding part 20.
- An adhesive layer 14 is provided on the first main surface 12 c of the cover glass 12.
- region in which the adhesion layer 14 is provided in the cover glass 12 is called the arrangement
- the shape of the cover glass 12 and the adhesive layer 14 is, for example, a rectangular shape, and the adhesive layer 14 is smaller in outer shape.
- the adhesive layer 14 is arranged with respect to the cover glass 12, for example, with its center aligned.
- a light shielding portion 20 is formed in a frame shape at the peripheral edge portion 12b of the peripheral edge of the arrangement region 12a.
- the light shielding unit 20 is configured to conceal a wiring member of a display panel, which will be described later, from the second main surface 12d side of the cover glass 12 so that it cannot be visually recognized.
- the light shielding portion 20 may not be provided.
- a protective film 16 that covers the entire surface of the cover glass 12 is detachably provided on the first main surface 14a of the adhesive layer 14. When the cover glass 10 with the adhesive layer is bonded to the in-vehicle display device, the protective film 16 is peeled off.
- the protective film 16 is not particularly limited, and for example, a relatively flexible film such as polyethylene or polypropylene is used.
- tempered glass such as chemically tempered glass and physical tempered glass is used, and among them, chemically tempered glass is preferable from the viewpoint of strength, design, cost, and the like.
- the glass type of the cover glass 12 include soda lime glass and aluminosilicate glass (SiO 2 —Al 2 O 3 —Na 2 O glass), among others, from the viewpoint of strength, Aluminosilicate glass is preferred.
- a compressive stress layer is formed on the surface of the cover glass 12 which is tempered glass.
- the thickness of the compressive stress layer is 10 ⁇ m or more, preferably 15 ⁇ m or more, more preferably 25 ⁇ m or more, and further preferably 30 ⁇ m or more.
- the surface compressive stress in the compressive-stress layer of the cover glass 12 which is tempered glass is 650 MPa or more, and preferably 750 MPa or more.
- a cover glass 12 for example, a tempered glass (for example, “Dragon Trail (registered trademark)”) obtained by subjecting an aluminosilicate glass to a tempering treatment is preferably exemplified.
- the glass material constituting the cover glass 12 is, for example, in mol%, SiO 2 50 to 80%, Al 2 O 3 1 to 20%, Na 2 O 6 to 20%, K 2 O. Glass materials containing 0 to 11% of Mg, 0 to 15% of MgO, 0 to 6% of CaO, and 0 to 5% of ZrO 2 .
- a method of obtaining a tempered glass (chemically tempered glass) by subjecting the glass to a chemical tempering treatment typically includes a method of immersing the glass in a KNO 3 molten salt, subjecting the glass to an ion exchange treatment, and then cooling to near room temperature.
- the treatment conditions such as the temperature and immersion time of the KNO 3 molten salt may be set so that the surface compressive stress and the thickness of the compressive stress layer have desired values.
- the cover glass 12 has a thickness of 0.5 to 2.5 mm. If the plate thickness is less than 0.5 mm, the strength of the cover glass 12 itself is insufficient, and the impact resistance may be reduced. On the other hand, if the plate thickness exceeds 2.5 mm, the plate becomes too thick, and is unsuitable for use in an in-vehicle display device from the viewpoint of design.

Abstract
Description
車載表示装置のタイプとしては、例えば、ダッシュボードの外部に立設されたスタンディングタイプ、ダッシュボードに埋め込まれた埋め込みタイプ等が挙げられる。
このような車載表示装置においても、表示パネル保護の観点からフィルム等の透明な保護部材が使用されているが、近年では質感の観点から、フィルムではなくガラスの保護部材(カバーガラス)の使用が望まれている。さらに、ガラスのなかでも、合わせガラスは厚くなりがちでデザイン上の問題が生じやすく、また、コストも高いことから、強化ガラスの使用が求められている。
すなわち、本発明の一態様に係る車載表示装置は、車両の内装部材に配置される車載表示装置であって、表示パネルと、上記表示パネルをカバーするカバーガラスと、上記表示パネルを収納する筐体と、上記筐体を位置保持する保持部と、を備え、上記カバーガラスが、板厚が0.5~2.5mm、圧縮応力層の厚さが10μm以上、圧縮応力層の表面圧縮応力が650MPa以上である強化ガラスであり、上記カバーガラスの板厚(単位:mm)をx、上記保持部のエネルギー吸収率(単位:%)をyとしたときに、下記式(1)を満たす、車載表示装置である。
y≧-37.1×ln(x)+53.7・・・(1)
なお、本実施形態では、車載表示装置を製造する方法として、粘着層付きカバーガラスを製造して、それを表示パネルに貼合する形態を一例として示すが、車載表示装置の製造方法はそれに限らない。例えば、OCA(Optically Clear Adhesive)フィルム等を介して、カバーガラスと表示パネルとを貼合してもよい。
図1は、粘着層付きカバーガラスを示す模式的断面図である。図1に示す粘着層付きカバーガラス10は、透明なカバーガラス12と、粘着層14と、保護フィルム16と、遮光部20とを有する。
カバーガラス12の第1主面12c上に粘着層14が設けられる。カバーガラス12において粘着層14が設けられる領域を配置領域12aと呼ぶ。
カバーガラス12および粘着層14の形状は、例えば長方形状であり、外形は粘着層14の方が小さい。粘着層14は、カバーガラス12に対して、例えば中心を一致させて配置される。カバーガラス12の第1主面12cにおいて、配置領域12aの周縁の周縁部12bには、遮光部20が枠状に形成されている。
遮光部20は、後述する表示パネルの配線部材等をカバーガラス12の第2主面12d側から視認できないように隠蔽するものである。もっとも、表示パネルの配線部材等が表示パネルを観察する側からは視認できない構造である場合等においては、遮光部20を設けなくてもよい。
粘着層14の第1主面14aには、カバーガラス12の全面を覆う保護フィルム16が剥離可能に設けられている。粘着層付きカバーガラス10を車載表示装置に貼合するときには、保護フィルム16が剥離される。保護フィルム16としては、特に限定されず、例えば、ポリエチレン、ポリプロピレン等の比較的柔軟なフィルムが用いられる。
カバーガラス12としては、化学強化ガラス、物理強化ガラス等の強化ガラスが用いられ、なかでも、強度、デザイン性、コスト等の観点から、化学強化ガラスが好ましい。
なお、カバーガラス12のガラス種としては、例えば、ソーダライムガラス、アルミノシリケートガラス(SiO2-Al2O3-Na2O系ガラス)等が挙げられるが、なかでも、強度の観点からは、アルミノシリケートガラスが好ましい。
強化ガラスであるカバーガラス12の表面には、圧縮応力層が形成される。圧縮応力層の厚さは10μm以上であり、好ましくは15μm以上、より好ましくは25μm以上、さらに好ましくは30μm以上である。
また、強化ガラスであるカバーガラス12の圧縮応力層における表面圧縮応力は、650MPa以上であり、750MPa以上であることが好ましい。
なお、カバーガラス12を構成するガラス材料としては、例えば、モル%表示で、SiO2を50~80%、Al2O3を1~20%、Na2Oを6~20%、K2Oを0~11%、MgOを0~15%、CaOを0~6%およびZrO2を0~5%含有するガラス材料が挙げられる。
カバーガラスの板厚は、0.7~2.0mmが好ましく、1.3~2.0mmがより好ましい。
なお、カバーガラス12の大きさの一例としては、例えば、矩形の場合、長手方向:100~800mm、短手方向:40~300mmが挙げられる。
粘着層14はカバーガラス12と同じく透明であり、カバーガラス12と粘着層14との屈折率差は小さいことが好ましい。
粘着層14としては、例えば、液状の硬化性樹脂組成物を硬化して得られる透明樹脂からなる層が挙げられる。硬化性樹脂組成物としては、例えば、光硬化性樹脂組成物、熱硬化性樹脂組成物などが挙げられ、なかでも、硬化性化合物および光重合開始剤を含む光硬化性樹脂組成物が好ましい。硬化性樹脂組成物としては、例えば、国際公開第2011/148990号に記載の層状部形成用光硬化性樹脂組成物が好適に挙げられる。
なお、粘着層14は、先述したようにOCAフィルム(OCAテープ)であってもよい。この場合、カバーガラス12上にOCAフィルムを貼合する。
粘着層付きカバーガラス10の製造方法について説明する。以下では、液状の樹脂組成物をカバーガラス12上に塗布し、それを硬化する場合の形態について説明する。
まず、カバーガラス12の周縁部12bに、遮光部20を枠状に形成する。そして、カバーガラス12の第1主面12c全面に遮光部20を覆って、硬化性樹脂組成物を、例えば、ダイコータ、ロールコータ等の方法を用いて塗布し、硬化性樹脂組成物膜(図示せず)を形成する。硬化性樹脂組成物膜は、後述するように切断されて粘着層14になる。
次に、得られた積層体において、粘着層14の側面14bとなる位置を切断線に設定し、レーザー光線を用いて、切断線で積層体を切断する。これにより、粘着層14の第1主面14aに保護フィルム16が設けられた粘着層付きカバーガラス10が得られる。
なお、予め硬化した粘着層14のフィルムをカバーガラス12上に貼合する場合や、樹脂組成物を精度良く塗布できる場合は切断工程を省略してもよい。
また、先述したように、粘着層14としてOCAフィルム(OCAテープ)をカバーガラス12上に貼合してもよく、この場合にも、切断工程を省略できる。
次に、本実施形態の車載表示装置100を説明する。
図2は、車載表示装置を示す模式的断面図である。本実施形態の車載表示装置100は、いわゆる埋め込みタイプの車載表示装置であり、ダッシュボード等の内装部材401に設けられた凹部411に埋め込まれて使用される。もっとも、車載表示装置としては、これに限定されず、例えば、スタンディングタイプの車載表示装置であってもよい。
粘着層付きカバーガラス10は、保護フィルム16を剥離した後、筐体106の開口部108を埋めるようにして、粘着層14を液晶パネル104の表示面104aに貼合する。これにより、車載表示装置100の表示面104aから筐体106の端面106aに至るまでカバーガラス12で覆われる。このようにして、カバーガラス12が、車載表示装置100の表示面104aの保護部材として機能する。
このとき、凹部411の底面411a上には、衝撃吸収性を有する衝撃吸収部としての直方体状のクッション材321が配置されている。すなわち、クッション材321は、筐体106の裏面側(開口部108とは反対側)に配置されている。このクッション材321によって、筐体106は、凹部411内で、所定の高さに位置付けられる。クッション材321としては、市販品を用いることができ、その具体例としては、ケー・シー・シー商会社製「CF45」が挙げられる。
なお、本実施形態では、筐体106の裏面側に配置される衝撃吸収部として、クッション材321を例示したが、これに限定されるものではなく、例えば、クッション材321以外の衝撃吸収性を有する部材;ハニカム機構、回転機構、摺動機構などの衝撃吸収性を有する機構;等であってもよい。
図3は、車載表示装置の変形例を示す模式的断面図である。図1および図2に基づいて説明した部分と同じ部分については同じ符号で示し説明も省略する。図3に示す車載表示装置100bは、筐体106の1辺のみを固定部301で保持した「片持ちタイプ」の車載表示装置であり、これをスタンディングタイプの車載表示装置とみなすこともできる。
筐体突出部111は、矩形である筐体底板107の四辺の縁に設けられていてもよいし、向かい合う一対の二辺の縁のみに設けられていてもよい。筐体突出部111は、基本的には、筐体底板107と一体の部材であることが好ましい。筐体突出部111は、一例として、図2に示すように、板状の部材であるが、固定部301およびボルト311によって接合されることができれば、その形状は特に限定されるものではない。
y≧-37.1×ln(x)+53.7・・・(1)
例えば、保持部が、固定部301とクッション材321等の衝撃吸収部とからなる場合、カバーガラス12の板厚に応じて、式(1)を満たす範囲内で、例えば、固定部301の形状、材質、板厚等を変更したり、衝撃吸収部であるクッション材321の材質を変更したり、衝撃吸収部としてクッション材321以外の部材または機構を選択したりする。
このような車載表示装置としては、例えば、車両のダッシュボードに埋め込まれた埋め込みタイプのカーナビゲーション装置などが挙げられ、さらに、カーナビゲーション装置以外の装置(例えば、インストルメントパネル)であってもよい。
カバーガラス12として、アルミノシリケートガラスに強化処理を施した強化ガラス(旭硝子社製商品名「ドラゴントレイル」、圧縮応力層の厚さ:38μm、圧縮応力層における表面圧縮応力:774MPa)を準備した。
カバーガラス12の第1主面12cに、粘着層14として、OCA(日栄化工社製「MHM-FWD」、厚さ:150μm)を積層し、粘着層付きカバーガラス10を作製した。
剛体模型を衝突させる試験(「ヘッドインパクト試験」ともいう)を行なうため、粘着層付きカバーガラス10を用いて、埋め込みタイプの車載表示装置の試験体200を作製した。図4~図6に基づいて試験体200を説明する。図4~図6においては、図1および図2の車載表示装置100と同一の(または対応する)部分は同じ符号を用い、説明を省略する。
図7は、固定部の変形例を示す模式的断面図である。図7に変形例として示す固定部301bは、板状部材を切り欠いたU字形状の部材である。固定部301bを断面視(側面視)すると、L字状ではなく、長手部分の途中が突出するように(波型に)屈曲している。
このとき、クッション材321が「2枚」の例では、図7中にL2~L9で示すサイズは、L2:50mm、L3:80mm、L4:20mm、L5:40mm、L6:14mm、L7:18mm、L8:18mm、L9:10mmとし、クッション材が「3枚」の例では、固定部301bを引き延ばし、L2の長さを長くした。
カバーガラス12の板厚は、0.56mm、0.7mm、1.1mm、1.3mmおよび2.0mmの5種とした。
図8は、試験体の変形例を示す平面図である。図4~図6に基づいて説明した部分と同じ部分については同じ符号で示し説明も省略する。図8に示す試験体200bでは、車載表示装置100b(図3参照)と同様に、筐体106の1辺(後述する衝突位置P側の1辺)のみを固定部301(または固定部301b)で保持している。このような「片持ちタイプ」の試験体200bを使用した例については、下記表1中、固定部に関する「L字」または「L字波型」の表記の後に「st」という文字を表記する。
・液晶パネル104…ソーダライムガラス(板厚1.1mm、サイズ:173mm×120mm)の両面に偏光板(材質:TAC)を貼合した代替品を用いた。
・バックライトユニット102…板状体102a(材質:PC、板厚:4mm、サイズ:117mm×170mm)の底面および4つの側面を凹状体102b(材質:アルミニウム、板厚:1mm)で覆った代替品を用いた。
・両面テープ207…材質:PET、テープ幅:5mm、テープ厚:0.5mm
・L字部材208…材質:PVC、板厚:1mm、L字1辺の長さ:5mm
・筐体枠109…材質:ABS、板厚:2mm
・筐体端枠110…材質:ABS、板厚:2.5mm、板幅:5mm
・両面テープ115…材質:PET、テープ厚:0.5mm
・固定部301…別途記載
・ボルト311…材質:鉄
・クッション材321…ケー・シー・シー商会社製「CF45」(厚さ:25.4mm)を1枚、2枚または3枚重ねたもの
・支持板215…材質:鉄、板厚:9mm
・筐体底板107および筐体突出部111…材質:鉄、板厚:1.15mm
このような試験体200において、各例ごとに、カバーガラス12の板厚と固定部301の材質、形状および板厚とを、下記表1に示すように変化させて、ヘッドインパクト試験を行ない、カバーガラス12の耐衝撃性を評価した。
すなわち、試験体200を用いたヘッドインパクト試験では、衝突時のエネルギーが「基準」と同等になるようにした。
なお、剛体模型の減速度に関しては、3ms(ミリ秒)以上連続して784m/s2(80G)を超えないことが規定されているが、今回行なった試験においては、全てこの規定を満たしていたことを確認している。
上記ヘッドインパクト試験を試験体200に対して行なった際の保持部(固定部301およびクッション材321)のエネルギー吸収率をシミュレーションによって算出した。
図9に示すように、剛体模型を試験体200に衝突させて剛体模型が持つ運動エネルギー(実線のグラフ)がゼロになった時(つまり、剛体模型が最下点となり速度が0(ゼロ)になった時)に、ほぼ同じ時点で、試験体200のひずみエネルギー(破線のグラフ)が最大値の152.4Jに到達している。このことから、衝突時には、剛体模型の運動エネルギーがほぼ全て、試験体200においてひずみエネルギーに変換されたことが分かる。
そして、保持部のエネルギー(点線のグラフ)についても、試験体200のエネルギー(破線のグラフ)と同様の挙動を示しており、剛体模型のエネルギー(実線のグラフ)がゼロになった時に、最大値に到達している。
このような図9から、剛体模型の衝突時の運動エネルギーの少なくとも一部が、保持部(固定部301、クッション材321)のひずみエネルギーに変換されたことが分かる。
例えば、衝突時における保持部のひずみエネルギーが「105J」であった場合は、エネルギー吸収率は、(105/152.4)×100=69[%]となる。
解析に際しては、カバーガラス12の長辺中央部に衝突させているため、計算時間短縮の観点から、1/2左右対称モデルを作成し、計算を行なった。また、試験体200の各部について、サイズのほか、密度ならびにヤング率およびポアソン比などの弾性率などの物性値をコンピュータに入力した。各部に用いた材質の物性値は、以下のとおりである。
・アルミニウム…ヤング率:68.6GPa、ポアソン比:0.34、密度:2.71×10-6kg/mm3
・ABS(アクリロニトリル・ブタジエン・スチレンの共重合体)…ヤング率:2.2GPa、ポアソン比:0.37、密度:1.05×10-6kg/mm3
・PC(ポリカーボネート)…ヤング率:2.2GPa、ポアソン比:0.38、密度:1.20×10-6kg/mm3
・PVC(ポリ塩化ビニル)…ヤング率:3.2GPa、ポアソン比:0.38、密度:1.4×10-6kg/mm3
・アルミノシリケートガラスに強化処理を施した強化ガラス(ドラゴントレイル)…ヤング率:74GPa、ポアソン比:0.23、密度:2.48×10-6kg/mm3
・MHM-FWD…ヤング率:10kPa、ポアソン比:0.30、密度:6.0×10-7kg/mm3
・TAC(トリアセチルセルロース)…ヤング率:4GPa、ポアソン比:0.30、密度:1.3×10-6kg/mm3
・ソーダライムガラス…ヤング率:73GPa、ポアソン比:0.23、密度:2.5×10-6kg/mm3
・PET(ポリエチレンテレフタレート)…ヤング率:5GPa、ポアソン比:0.25、密度:1.34×10-6kg/mm3
なお、実際の解析では、各ひずみ速度毎の応力ひずみ線図を入力データとし、各曲線間のデータについては、補間して計算を実行している。
引張試験のため、各材料ともに図10に示す試験片(厚さ:2.0mm)を作製した。
なお、図10に示す試験片の厚さ以外のサイズは、鉄およびアルミニウムについては、S1:17mm、S2:11mm、S3:8mm、S4:16mm、S5:8.5mm、S6:4mm、S7:5mmとし、図10中に符号Rで示すコーナー部の丸みは、半径1.5mmとした。
一方、ABS、PCおよびPVCについては、S1:17mm、S2:9.2mm、S3:8mm、S4:16mm、S5:8.5mm、S6:2mm、S7:5mmとし、図10中に符号Rで示すコーナー部の丸みは、半径0.6mmとした。
なお、ひずみ速度については、仮に、初期平行部長さ(図10中、符号S3で表す)が25mmである試験片を用いて、クロスヘッド速度をヘッドインパクト衝突速度(6700mm/s)として試験を行った場合には、その初期ひずみ速度(単位:s-1)は、6700/25=268s-1となる。
このため、ひずみ速度を100s-1、500s-1もしくは1000s-1としてホプキンソンプレッシャーバーを用いて、または、ひずみ速度を0.01s-1もしくは1s-1として検出ブロック式材料試験機を用いて、引張試験を行なった。
まず、クッション材321を所定の形状(厚さ:25mm、サイズ:100mm×500mm)に切り取り、これを、直径200mmの金属製円盤どうしで挟み込み、10kNロードセル(オートグラフ)を用いて、上から5mm/分、0.1m/分、1m/分の速度で荷重をかけ、その際の荷重および変位量から、圧縮でのひずみ速度依存性を考慮した(低速での)応力ひずみ線図を作成した。
次に、より高速での応力ひずみ線図も得た。具体的には、まず、上述したヘッドインパクト試験と同様にしてクッション材に対して落下高さを変えて剛体模型を落下させ、クッション材の沈み込み量を高速度カメラでの撮影により測定した。このとき、ひずみ速度がより高速の10s-1、100s-1、200s-1における沈み込み量も測定した。そして、低速での沈み込み量と応力ひずみ線図とを参考にして、高速での沈み込み量から、高速での応力ひずみ線図を作成した。
なお、実際の解析では、各ひずみ速度毎の応力ひずみ線図を入力データとし、各曲線間のデータについては、補間して計算を実行している。
一般的に、ひずみエネルギーの計算は、以下のような理論式により算出される。上述した市販のプログラムを用いた解析においても、各部材に関して入力された応力ひずみ線図から、以下の式によって計算機で計算を行なっている。なお、本衝撃解析では、部材の破断までは考慮していない。
まず、ひずみエネルギーUおよびひずみエネルギー密度U*は、次のようになる。
dεおよびdγのひずみ増分の間に単位体積当たりに蓄えられるひずみエネルギー、すなわち、ひずみエネルギー密度の増分dU*は、下記式(2)で与えられる(図11参照)。
図12に示すグラフから明らかなように、式(1)を満たさない場合(比較例)はカバーガラスが割れるのに対して、式(1)を満たす場合(実施例)にはカバーガラスが割れないことが分かった。
なお、本出願は、2015年6月5日付けで出願された日本特許出願(特願2015-114616)に基づいており、その全体が引用により援用される。
