Description
次に、本発明の一実施形態による表示装置用ウィンドウパネルについて図1を参照して
説明する。
以下、実施例を通じて本発明をより詳しく説明する。ただし、下記の実施例は単に説明の目的のためのものであり、本発明の範囲を制限するものではない。
(実施例1)
ポリメチルメタクリレート(polymethylmetacrylate、PMMA)基板をアクリル樹脂、エポキシ樹脂およびメチルエチルケトン(methyl ethyl ketone、MEK)を混合した高分子溶液に浸漬してコーティングした後、乾燥した。このようなコーティングおよび乾燥をさらに4回繰り返して総5層のハードコーティング層を形成した。
ポリメチルメタクリレート(PMMA)基板をアクリル樹脂、エポキシ樹脂およびメチルエチルケトンを混合した高分子溶液に浸漬し乾燥して1層のハードコーティング層を形成した。次に、前記基板をポリシルセスキオキサン溶液に浸漬し乾燥して2層のハードコーティング層を形成した。
ポリメチルメタクリレート(PMMA)基板をアクリル樹脂、エポキシ樹脂およびメチルエチルケトンを混合した高分子溶液に浸漬し乾燥して1層のハードコーティング層を形成した。次に、1層のハードコーティング層が形成された基板をポリシルセスキオキサン溶液に浸漬し乾燥して2層のハードコーティング層を形成した。次に、2層のハードコーティング層が形成された基板を前記高分子溶液に浸漬し乾燥して3層のハードコーティング層を形成した。
ポリメチルメタクリレート(PMMA)基板をアクリル樹脂、エポキシ樹脂およびメチルエチルケトンを混合した高分子溶液に浸漬し乾燥して約5μm厚さの単一層のハードコーティング層を形成した。
ポリメチルメタクリレート(PMMA)基板をアクリル樹脂アクリル樹脂、エポキシ樹脂およびメチルエチルケトン(methyl ethyl ketone、MEK)を混合した高分子溶液に浸漬し乾燥して約10μm厚さの単一層のハードコーティング層を形成した。
ポリメチルメタクリレート(PMMA)基板をポリシルセスキオキサン溶液に浸漬し乾燥して約10μm厚さの単一層のハードコーティング層を形成した。
鉛筆硬度試験器(製造会社:BMS Tech)を使用し、1kg荷重をかけて実施例1と比較例1、2によるウィンドウパネルの表面硬度を測定した。
ハードコーティング層の厚さおよび表面硬度は表1の通りである。
実施例2、3と比較例2、3によるウィンドウパネルの表面硬度を測定した。
その結果は表2の通りである。
実施例1〜3によるウィンドウパネルの中央部分に130gの錘を落下させるボールドロップ測定器を使用して耐衝撃性を測定した。
