曲面(LCD/OLED)テレビの分析(市場、技術、プロセス、製品) Curved (LCD/OLED) TV Analysis (Market, Technology, Process, Product)
出版日: 2014年01月02日 ページ情報: 英文 144 Pages
概要

2000年初頭に登場したフラットパネルディスプレイ(FPD)テレビは、従来のブラウン管テレビを市場からほぼ駆逐しました。その間、プラズマディスプレイ(PDP)と液晶ディスプレイ(LCD)が競い合う時期もありましたが、競争の激化に伴ってPDPメーカーの多くが撤退、現在は、新たに登場したOLEDディスプレイがLCDテレビの市場支配に挑戦するという構図になっています。LCDシステム自体も進化を続けており、LEDバックライトや3D技術の導入、3840×2160の解像度を有する4Kテレビの開発などさまざまな動きが見られます。なかでも近年特に注目を集めているのが曲面ディスプレイです。4Kテレビのような超高精細(UHD)ディスプレイは、大画面でも臨場感のある映像を見ることができますが、スクリーン端部では視野角の影響で画像が歪み、解像度も低下します。曲面ディスプレイは、この問題を解決するための技術であり、コントラスト比を犠牲にすることなく画像品質を高めることができることから、ソニーやSamsung Electronicsなど各社が相次いで製品を投入しています。

当レポートは、曲面テレビ技術に焦点を絞り込み、市場の全般的なトレンド、問題点や対策などを明らかにしたもので、技術面の詳細な分析に加え、製品の開発状況や曲面テレビの将来像などについても検討し、概略以下の構成でお届けいたします。

Since the introduction of flat panel display TVs in early 2000, the presence of CRT TVs has almost disappeared. Due to competition between PDPs and LCDs, not many PDP producers have stayed in the PDP business. Moreover, Panasonic, a leading PDP producer, recently terminated its PDP TV business. In a little over 10 years, LCDs have become a major TV technology and the flat panel display market is about to face challenges of OLED display technology.

For the past ten years, LCD TV products have been making improvements and featuring new designs and systems. Every year, LCD systems have been developed to make improvements that included integrating LED back lighting units, realizing high definition and 3D TVs. Now TV producers are hoping to revive the stagnant TV market by introducing ultra high definition (UHD), which is in 3840 x 2160 (4K2K) resolution format TV. The UHD TV is known to deliver on a large screen a realistic image quality viewing experience; however, its distortion on the edges of the screen and low contrast ratio based on viewing angles issues that most need improvement. As a solution, the industry suggests that a curved display, which is capable of offering a realistic screen quality without sacrificing the contrast ratio by designing curvature screen that maintains an optimum viewing distance between viewers the center and edges of the display.

Despite a sluggish economy, TV producers are trying to promote TV demand by adapting the UHD TVs and large curved TVs to attract potential TV buyers.

Toward the latter part of 2013, the set makers have introduced curved TVs. Starting with Sony's 65" FHD Curved LCD TV in September 2013, Samsung Electronics unveiled a world's first 65" curved UHD LCD TV and a 55" curved UHD OLED. Then in October 2013, LGE introduced the world's first 77" curved UHD OLED TVs during IFA. Changhong, a leading Chinese brand, also exhibited its 55" FHD LCD TV at the IFA show. Newer and better-curved TVs are expected by CES 2014. The industry expects that curved and/or UHD TVs will enter into strong competition in 2014.
