1. What is an FHD display?
FHD, the full name of which is Full High Definition, is a display technology with a 解决 of 1920×1080 pixels. This resolution can provide clear and detailed images, bringing users a high-quality visual experience.
Compared with other resolutions:
- HD (High Definition):
Usually refers to the resolution of 720p or 1080i. Although it can also provide relatively clear images, it lacks the number of pixels and image details compared to FHD. Screens with HD resolution may appear slightly rough when playing HD videos, especially on large-screen devices.
- 4K (Ultra High Definition):
The resolution is 3840×2160 pixels, which is four times that of FHD. 4K screens far exceed FHD in clarity, color reproduction and detail display, and can bring a more realistic visual experience. However, 4K content is relatively rare, has high hardware requirements, and is relatively expensive.
The advantage of FHD in clarity is that its moderate resolution can ensure the clarity of the image without placing too much burden on the hardware. At the same time, it is compatible with most application scenarios. However, compared with 4K, FHD still has certain limitations in detail display and color reproduction.

2. Introduction to LED display screens
LED显示屏, the full name of which is Light Emitting Diode, is a semiconductor device that can convert electrical energy into light energy. Its light-emitting principle is based on the electroluminescent effect of semiconductor materials.
When current passes through the semiconductor P-N junction, electrons and holes recombine to release energy and emit light in the form of photons. LED displays have significant advantages, such as high efficiency, long life, and environmental protection.
Advantages of LED:
High efficiency: LED display light sources have high luminous efficiency and can convert more electrical energy into light energy, reducing energy waste.
长的 生活: LED displays have a long service life, generally up to tens of thousands of hours, far exceeding traditional light sources.
Environmental protection: LED display does not contain harmful substances, such as mercury, and does not pollute the environment during production and use, which is in line with the concept of green environmental protection.
1). LED显示技术
1.1). Backlight technology analysis:
- Direct backlight:
LED lamp beads are arranged directly behind the LCD panel to provide a uniform and sufficient light source.
This method can improve the brightness and contrast of the picture but may lead to increased screen thickness and energy consumption.
- Side-entry backlight:
LED lamp beads are arranged at the screen frame, and the light is evenly distributed to the entire screen through the light guide plate. This method helps to reduce screen thickness and energy consumption, but there may be uneven brightness problems at certain angles.
1.2). Color management and brightness adjustment:
- Color management:
LED display screens achieve rich color performance by precisely controlling the brightness and proportion of the three primary color LEDs: red, green, and blue. Advanced color management technology can improve color saturation and accuracy, making the picture more vivid and realistic.
- 亮度 adjustment:
LED display supports intelligent dimming technology, which can automatically adjust the screen brightness according to the ambient light and viewing needs. This can not only improve viewing comfort, but also effectively save energy.
2). Advantages and challenges
2.1). Advantages:
High brightness: LED display has a high brightness level, which can ensure clear and visible images even in strong light environments.
Wide color gamut: By precisely controlling the light-emitting characteristics of LEDs, LED displays can cover a wider range of color gamuts and present richer colors.
Fast response time: The response time of LED displays is extremely short, and they can quickly respond to changes in image signals, reducing smearing and blurring.
2.2). Challenges:
Energy consumption control: As the brightness and resolution of LED displays increase, their energy consumption also increases accordingly. How to reduce energy consumption while ensuring picture quality is an important challenge currently faced.
Color consistency: Due to the differences in the light-emitting characteristics of LED lamp beads, how to ensure the color consistency of the entire screen is another problem that needs to be solved.
Cost reduction: Although LED displays have significant advantages in performance, their manufacturing costs are still high. How to further reduce costs to promote their popularization and application is one of the current focuses of the industry.
3. The integration and differences between FHD and LED displays
1). Combined application
- The prevalence and advantages of FHD+LED combination products:
In the market, the combination of FHD (full high definition) and LED (light-emitting diode) technology is very common, especially in the field of television. LED backlight FHD TV is a typical representative of this combination.
This combination makes full use of the high resolution of FHD and the high brightness and wide color gamut of LED backlight to provide users with a better visual experience.
LED backlight technology can significantly improve the brightness level of FHD TVs so that the picture is still clearly visible in bright environments. At the same time, the wide color gamut characteristics of LED also make the color performance more vivid and rich.
For example, in a commercial exhibition center, all exhibitors hope to display their products or services in the most attractive way. At this time, a huge FHD+LED display screen has become the focus of the exhibition.
This display screen not only occupies one wall of the exhibition area but also attracts a large number of visitors with its excellent picture quality and brightness.
- How to further improve the display effect:
The combination of FHD+LED not only improves the display effect of TV but also meets the user’s demand for high-definition picture quality and excellent color performance. In order to further improve the display effect, manufacturers are also constantly optimizing LED backlight technology and color management technology.
For example, the use of more advanced LED lamp beads and more sophisticated backlight partition control technology can further improve the contrast and color uniformity of the picture.
At the same time, intelligent dimming technology and color calibration technology can ensure the best display effect in different lighting environments.
