Description
本実施形態の表示装置は、液晶表示パネルPNLと、回路基板10と、フレキシブル基板20と、を備えている。
ソースドライバSD1は、電源チャージポンプ回路1と、レシーバ2と、タイミングコントローラ3と、電源回路4と、バッファMと、通信部5と、を備えている。
以下に、比較例の表示装置をについて図面を参照して説明する。
図3は、比較例の表示装置におけるソースドライバ、回路基板およびフレキシブル基板の一構成例を概略的に示す図である。なお、以下の説明において、上述の実施形態と同様の構成については、同一の符号を付して説明を省略する。
なお、上述の実施形態では、複数のソースドライバSD1〜SDn間で、TTL信号(24ビットの階調信号)の映像信号を通信していたが、通信部5間でLVDS信号である映像信号を通信するように構成されても構わない。その場合には、スレーブドライバであるソースドライバSD2〜SDnは、LVDS信号である映像信号をTTL信号である映像信号に変換する変換手段を更に備え、ソースドライバSD1〜SDnは、変換手段により変換された映像信号を夫々対応する信号線SLへ出力する。
