LEDディスプレイの視野角の定義
The viewing angle of an LED display refers to the range of angles from which the screen can be comfortably and clearly viewed without a significant decrease in image quality or color accuracy. In other words, it indicates the maximum angle at which a viewer can watch the screen while still perceiving the displayed content accurately and without any visual distortions.
As LED displays have become increasingly prevalent in various applications such as televisions, computer monitors, digital signage, and mobile devices, understanding and optimizing the viewing angle have become crucial factors in delivering a satisfying visual experience to the users.
To fully grasp the concept of viewing angle in LED displays, it is essential to delve into the technology and principles underlying LEDのdisplayですand their optical properties.
Manufacturers often provide specifications for viewing angles based on the points where the brightness or color deviation reaches a certain threshold, such as 50% or 10%, from the optimal center view.
- Wide viewing angle: This implies that the display can be viewed comfortably from a broad range of angles without significant loss in image quality. Wide viewing angles are essential for applications where the audience may be scattered or where multiple viewers are watching the screen simultaneously.
- Narrow viewing angle: A narrow viewing angle means that the display's image quality degrades significantly when viewed from off-center positions. This type of display is suitable for applications where a limited audience views the screen from a fixed location, reducing the risk of unintended viewers observing distorted content.
- Vertical versus horizontal viewing angles: LED displays often have different vertical and horizontal viewing angles. For instance, a display may have a wide horizontal viewing angle for better side-to-side visibility in a public display, while having a more limited vertical viewing angle to protect the content's privacy.

1. LEDディスプレイの基本原理:
LED stands for Light-Emitting Diode, and it is a semiconductor device that emits light when an electric current passes through it. In an LED display, thousands or even millions of individual LEDs are grouped together to form pixels. Each pixel typically consists of three sub-pixels (red, green, and blue) that can produce various colors when they emit light at different intensities. These pixels are arranged in a matrix to form the complete display panel.2.画質への影響:
When viewing an LED display from the front (perpendicular to the panel's surface), the observer receives the maximum radiant intensity from the LEDs, resulting in optimal image quality. However, as the viewer moves away from the center, the angular dependence of LED emission becomes apparent, and the observed brightness decreases. Additionally, the color and contrast may also change, leading to reduced image quality and, potentially, color shifts.3.視野角の測定:
The viewing angle of an outdoor or 屋内用LEDディスプレイ is typically measured in two directions: horizontal and vertical. The two angles define the cone within which the screen can be viewed with an acceptable image quality.- - 水平視野角:これは、許容可能な画質を維持しながら、ディスプレイを左側または右側から見ることができる最大角度を指します。
- - 垂直方向の視野角: これは、許容可能な画質を維持しながら、ディスプレイを上または下から表示できる最大角度を表します。
Manufacturers often provide specifications for viewing angles based on the points where the brightness or color deviation reaches a certain threshold, such as 50% or 10%, from the optimal center view.
4.視野角に影響を与える要因:
Several factors influence the viewing angle characteristics of LED displays:- - LEDテクノロジー:ディスプレイに使用されているLEDの種類は、その視野角に影響を与えます。直視型LED、エッジライトLED、OLEDなどのLED技術が異なれば、発光角度も異なります。
- - 画素の構造と配置:画素の配置と配置は、視野角の特性を決定する役割を果たします。たとえば、一部のディスプレイは、視野角を改善するために特別な配置または技術を使用する場合があります。
- - パネル構造:ディスプレイパネル自体の設計と構造は、視野角に影響を与える可能性があります。基板材料や追加の光学層(偏光子など)の存在などの要因は、光の放出と透過の方法に影響を与える可能性があります。
- - 視野角補正:メーカーは、特に屋外や周囲光の多い条件で、視野角を改善し、反射を減らすために、アンチグレアコーティングや光学フィルムなどの技術を採用する場合があります。
- - ディスプレイのサイズ: ディスプレイのサイズは、視野角の認識に影響を与える可能性があります。大型ディスプレイは、全体的な表面積により、角度特性がわずかに異なる場合があります。
- - 画像の内容と品質: 表示されるコンテンツの種類とその解像度は、ユーザーが視野角をどのように認識するかに影響を与える可能性があります。高品質のコンテンツは、より広い範囲の角度でより一貫性があるように見える場合があります。
5.視野角の種類:
Understanding the different types of viewing angles helps assess the quality of an LED display for specific applications:- Wide viewing angle: This implies that the display can be viewed comfortably from a broad range of angles without significant loss in image quality. Wide viewing angles are essential for applications where the audience may be scattered or where multiple viewers are watching the screen simultaneously.
- Narrow viewing angle: A narrow viewing angle means that the display's image quality degrades significantly when viewed from off-center positions. This type of display is suitable for applications where a limited audience views the screen from a fixed location, reducing the risk of unintended viewers observing distorted content.
- Vertical versus horizontal viewing angles: LED displays often have different vertical and horizontal viewing angles. For instance, a display may have a wide horizontal viewing angle for better side-to-side visibility in a public display, while having a more limited vertical viewing angle to protect the content's privacy.
6.適切な視野角を選択する方法は?
At present, the viewing angles of most LED display manufacturers are unified. For a high-quality LED display product, the larger the viewing angle, the fewer blind spots, and the better the viewing effect of the audience from different angles.- - 小さな待ち合わせ場所、推奨:水平60〜90度、垂直60度
- - 大規模な会議場所、推奨:90〜160度、垂直方向に90度以上
- - 超大規模な会議会場の場合、水平方向に160〜180度、垂直方向に90度以上を推奨します。
- - 屋内コンサート、推奨:水平90〜120度、垂直60度
- - 野外コンサート、推奨:水平120〜160度、垂直60〜90度
結論
The viewing angle of an indoor or 屋外用LEDディスプレイ is a critical factor in determining the user experience and the display's suitability for various applications. Understanding the underlying principles and trade-offs involved in achieving different viewing angles can help users and manufacturers make informed decisions about selecting and optimizing LED displays for specific purposes. Advancements in LED technology and display engineering continue to push the boundaries of viewing angles, ensuring that users can enjoy vibrant and clear content from a wide range of positions.If you want to know more information about LED Display, お問い合わせください.
