準備はできていますか?LCD 市場は LED ディスプレイに置き換えられようとしています

序章

In the vast universe of science and technology, display technology has always been an important force leading the visual revolution. From the early cathode ray tube (CRT) to today’s liquid crystal display (LCD), every technological leap has greatly enriched people’s visual experience and promoted the rapid development of the information society.

However, with the continuous advancement of science and technology, LED (light-emitting diode) display, as a representative of the new generation of display technology, is quietly changing the pattern of the display market with its unique advantages.

1. Comparison of LCD and LED display technology

1). Technical principle

  • LCD (liquid crystal display):

Imagine that you have a piece of transparent plastic in your hand, which is filled with small liquid particles (liquid crystal). When you shine a light on it, by controlling the arrangement of these liquid particles, you can let the light pass or block the light, thereby displaying the image.

This is how LCD screens work, but it uses many such small particles (pixels) to combine to display the entire picture.

  • LED (light-emitting diode) display:

LED is a small light bulb that emits light, and each LED can emit light of different colors.

The LED display is arranged with many small bulbs (LED beads) like this, each of which can independently control the brightness and color, and when combined, it can display very bright and clear images. Moreover, these LED beads are self-luminous and do not need an additional light source like LCD.

2). Display effect

The color of the LED display is more vivid because it can directly emit light of various colors. Although LCD can also display rich colors, it is softer in comparison.

LED also has a higher contrast, with black parts being blacker and white parts being brighter. In terms of brightness, LED can be adjusted to be very bright as needed, which is suitable for use outdoors or in places with strong light.

When looking at LED displays from all angles, the color and brightness are similar, while LCD screens may see the color fade or darken at certain angles.

3). Energy consumption and environmental protection

  • エネルギー消費:

LED display is more energy-saving than LCD. Because LED is self-luminous and has high luminous efficiency, LED consumes less electricity at the same brightness.

  • 環境を守ること:

Although both LED and LCD contain some materials that are not good for the environment, more and more manufacturers are now working hard to improve and use more environmentally friendly materials.

Moreover, when these displays are no longer in use, they also need to be properly handled to avoid environmental pollution. However, from the perspective of energy consumption, LEDs are more energy-efficient, so they have less impact on the environment during use.

2. Technological innovation, the driving force of market growth for LED displays

  • Miniaturization and high-integration technology:

With the advancement of science and technology, the manufacturing technology of LED displays is also constantly innovating. Miniaturization technology makes the size of LED lamp beads smaller and smaller, which means that more LED lamp beads can be accommodated in the same area, thereby improving the resolution and fineness of the display.

At the same time, the development of high-integration technology makes the circuit design and control system of LED displays more compact and efficient, reduces energy consumption, and improves overall performance. These technological innovations make it possible for LED displays to be used in more fields.

  • Continuous performance improvement:

In addition to miniaturization and high-integration technology, LED displays are also continuously improving in key performance indicators such as display resolution and refresh rate.

High resolution means that the picture is more delicate and clear, and can show more details; a high refresh rate can reduce the phenomenon of image smearing and blurring, and improve the smoothness of dynamic pictures.

These performance improvements make LED displays more competitive in scenes that require high-quality display, such as video playback and game entertainment.

1). Application scenario expansion

  • Wide application in traditional fields:

LED display screens have been widely used in commercial advertising, sports events, large outdoor screens, and other fields. In commercial advertising, LED display screens have attracted a lot of attention with their bright colors and flexible display methods.

In sports events, large LED display screens have become an important medium for live audiences and TV viewers to enjoy the game; in the field of outdoor large screens, LED display screens have become an important part of the urban landscape with their high brightness and wide viewing angle characteristics.

  • Development of emerging markets:

In addition to traditional fields, LED display screens are constantly exploring new application markets. With the growth of home entertainment demand, LED display screens have begun to enter family living rooms, bedrooms, and other spaces, providing users with a more immersive viewing experience.

At the same time, in-vehicle display is also an important development direction for LED display screens. With the popularization of autonomous driving technology and the improvement of automobile intelligence, LED display screens have broad application prospects in in-vehicle entertainment, navigation, and other aspects.

2). Policy support and industry standards

  • Government incentive policies:

In order to promote the development and application of energy-saving and environmentally friendly technologies, governments of various countries have introduced a series of incentive policies.

These policies not only provide financial support for the research and development and production of energy-saving and environmentally friendly products such as LED display screens but also reduce the production costs and market risks of enterprises through tax incentives, subsidies, and rewards.

In addition, the government has also improved the public’s awareness and acceptance of energy-saving and environmentally friendly technologies such as LED displays through demonstration projects, publicity, and promotion.

  • Formulation and promotion of industry standards:

In order to regulate market order, improve product quality, and promote technological innovation, relevant international and domestic institutions and organizations are also constantly formulating and improving technical standards and testing and certification systems for LED displays.

These standards and systems not only provide scientific basis and technical guidance for product design, production, and sales but also provide consumers with more reliable product selection and protection.

At the same time, the formulation and promotion of industry standards also promote cooperation and exchanges between enterprises and promote the healthy development of the entire industry.

3. Why will LCD be replaced by LED displays?

The trend of LCD (liquid crystal display) being replaced by LED displays does not mean that LCD is completely replaced by LED screens, but that LED backlight technology or LED displays have significant advantages over traditional LCDs in some aspects, thus gradually occupying a dominant position in specific fields. Here are several main reasons:

1). 技術的な利点
