A few days ago, the Ministry of Industry and Information Technology, the State Administration of Radio and Television, and China Central Radio and Television jointly issued the "Ultra HD Video Industry Development Action Plan (2019-2022)". It is estimated that by 2022, the overall scale of my country's ultra-high-definition video industry will exceed 4 trillion yuan, the number of ultra-high-definition video users will reach 200 million, the 4K industry ecosystem is basically complete, and breakthroughs will be made in the development and industrialization of 8K key technology products. In fact, the ultra-high-definition LED display has become a very obvious trend. With the successive introduction of relevant national policies and the increasing attention and demand for the ultra-high-definition display industry, the development of the ultra-high-definition video industry will definitely promote the ultra-high-definition video industry. The increasing demand for high-definition terminals will also have a profound impact on the development of high-definition LED displays. For LED display companies, the market size of the ultra-high-definition video industry continues to expand, which will surely bring a new round of development opportunities to the industry.
It is foreseeable that a 4K ultra-high-definition storm pioneered by Guangdong Province is spreading across the country. Based on a strong industrial foundation, Guangdong Province vigorously promotes the implementation of 4K ultra-high-definition video. As an important part of the ultra-high-definition industry chain, the LED display industry Since its inception, it has experienced early single and double color to full color, and then to today's small-pitch ultra-high-definition display, and even the development of Mini/Micro LED. The entire industry has maintained its innovative vitality, trying different processes to break the technical shackles, LED display The screen has made a qualitative leap in the display effect, high-definition, or even ultra-high-definition display, which is currently a very important direction for the development of LED displays, and the release of the "action plan" has brought inflectional opportunities to the entire industry. It will become a huge driving force to promote the continuous progress of LED display technology, and a new round of audio-visual war has begun for hundreds of companies and millions of industry employees.
（1）どのようなLEDディスプレイが高精細ディスプレイになることができますか？
Entering the era of high-definition, it is first necessary to clarify what is high-definition. High-definition LED display is defined by the "high-definition" that is commonly used in televisions at present. 720P is a high-level high-definition digital TV set by the Society of Motion Picture and Television Engineers (SMPTE). 1080i and 720p are internationally recognized digital high-definition television standards. Therefore, the 1080i format has a resolution of 19201080i/60Hz, a line frequency of 33.75kHz, 720p format, and a resolution of 1280720p/60Hz. The frequency is 45kHz, 1080p format, and the resolution is 19201080 progressive scan. All professional format displays can be defined as high-definition LED displays.
高解像度のLEDディスプレイの実現は、LEDディスプレイのドットピッチがますます小さくなることを意味する必要があります。 LEDディスプレイのドットピッチを小さくすると、鮮明度が向上し、より繊細な画像を表示できます。 第二に、コントラストも視覚効果に影響を与えます。 重要な要素の1つは、一般的に言えば、コントラストが高いほど、画像をより鮮明でより多くの目で捉えることができ、-より明るく、より明るい色になります。 高コントラストは、画像の鮮明さ、細部のパフォーマンス、およびグレーレベルのパフォーマンスに非常に役立ちます。 コントラストは、動的なビデオ表示効果に大きな影響を与えます。 動的画像の明るい-暗い遷移は高速であるため、コントラストが高いほど、人間の目はそのような変換プロセスを区別しやすくなります。
（2）超-高-定義の時代では、置換効果が強化されます
Under the call of the ultra-high-definition era, as the small-pitch LED large-screen display technology matures and user needs continue to change, more and more end users choose small-pitch LED large screens, DLP projection, LCD panel splicing screen traditional application scenarios , Such as hotels, conference venues, exhibitions, monitoring centers, etc. will gradually be replaced by LED ultra-high-definition displays. In the past, the large-screen splicing market was relatively low-end. It only upgraded and transformed traditional desktop LCD monitors and applied them to the market. There were many drawbacks, such as insufficient resolution, which made it difficult to reach the level of 1080p, while DLP projection was The lack of color performance, and the overall stability that needs to be strengthened, have created opportunities for the development of LED displays. In today's high-definition era, ultra-high-definition LED display screens are now very exquisite. Then there are products that can only be viewed from a distance.
LED大画面-スクリーンディスプレイテクノロジーは、DLPプロジェクション、LCDパネルスプライシングスクリーン、およびその他のディスプレイテクノロジーとは明らかに異なります。 小さい-ピッチLEDウルトラ-高-定義画面の最大のハイライトは、視覚的な体験です。 その高い色再現能力は、色の信憑性を完全に保持し、バックライト、投影などのディスプレイ技術、科学的な光混合および色混合設計、ポイント{{4 }} by -ポイント補正テクノロジーにより、トゥルーカラー再現を実現し、シームレスディスプレイテクノロジーが成熟するにつれて、LEDウルトラ-ハイ-解像度ディスプレイを継ぎ目の痕跡なしで実現できます。シームレスな平面のように、明るい色と完全な画像を備えています。 大画面の-画面表示システムは、緊急コマンドセンター、ホテル、会議場、展示会、監視センターのフロント-エンド表示レイヤーとして機能します。 表示効果はビジネスプラットフォーム機能の表示に直接影響し、それによってコマンドおよびディスパッチ作業の効率、画像表示効果などに間接的に影響します。超-高-解像度LEDディスプレイは強力な力になりましたそれは、ますます重要な技術的利点、長い耐用年数、および幅広い適応可能な環境のために無視することはできません。
データによると、2018年の屋内の小さな-ピッチの市場規模は19.97億米ドルで、主に超-ファイン-の継続的な発酵により、年間39％の成長を遂げました。将来のピッチトレンド。 現在、LED小型-ピッチディスプレイの最大の商業市場は、企業、教育、およびハイエンド-エンドから来ています。小売店、ホテル、劇場、その他の文化的および娯楽施設では、LEDディスプレイの普及率はこれらのアプリケーション分野では高くはなく、将来的には従来のLCD、DLP、プロジェクションディスプレイに取って代わる大きな成長の可能性があり、LEDディスプレイ企業の成長ポイントにとって重要な未来になります。
To be sure, the ultra-high-definition display era is destined to be an era of "a hundred schools of thought", and it will play a decisive role in the upgrading of the industry. Judging from the general trend of the current LED display development, the industry will set off a "ultra-high-definition display" boom in 2019, which will have a huge impact on the advancement of the industry's technology and technology and the expansion of the market. The era of ultra-high-definition display will be more In an era when a variety of display technologies compete for the commanding heights of ultra-high-definition displays in the future, no matter which technology can dominate the future, it is related to the future of the industry. With the advent of the ultra-high-definition display era, where will LED display companies go? In terms of technology development, what kind of situation will small-pitch, COB, Mini LED, and MicroLED present, will become a topic for companies to explore and research. .
