مقدمة
Unlike traditional flat LED displays, شاشات LED مرنة can present a variety of shapes, such as arcs, waves, spheres, and even twists, to meet the needs of various special scenes. Therefore, when choosing a flexible LED display, the choice of pixel pitch is particularly important.
Pixel pitch not only directly affects the clarity and viewing effect of the picture but is also closely related to the cost and manufacturing difficulty of the display. So, how do flexible LED displays generally choose pixel pitch?
1. Brief introduction to flexible LED displays and pixel pitch
1). Features of flexible LED displays
Flexible LED displays, also known as LED soft screens, have a series of unique characteristics.
- Material and structure:
Flexible LED displays are mainly composed of flexible modules, which contain high-strength magnetic core connection devices, flexible FPC circuit boards made of flexible insulating substrates, and high-temperature and bending-resistant silicone materials.
Compared with traditional LED displays, the circuit boards of flexible LED displays are made of special flexible materials, so they will not break due to bending. This design makes flexible LED displays more flexible and plastic.
- Plasticity:
Flexible LED displays can be bent, folded, and stretched freely and can easily adapt to various complex scenes. It can present flat, curved, spherical, and three-dimensional shapes, suitable for different scenes and needs.
This plasticity makes flexible LED display screens widely used in scenes such as artistic modeling, الفندق advertising, stages, مراكز التسوق، gymnasiums, معرض halls, etc.
Especially when dealing with irregular buildings and structures, flexible LED display screens can meet various design needs and show unlimited creativity.
- Advantages in special shape display:
Flexible LED display screens have significant advantages in special shape display. For example, in columnar and arched scenes, flexible LED display screens can create unique visual effects, adding a dreamy and novel atmosphere to the space.
In addition, flexible LED display screens are easy to bend and splice and can be installed in a variety of ways, such as floor installation, hanging installation, embedded installation, etc., with fewer restrictions on the installation area.
This makes flexible LED display screens an ideal choice for creating amazing visual experiences.
2). Definition and importance of مساحة وحدة الصورة
- Definition of pixel pitch:
Pixel pitch refers to the distance between the centers of two adjacent pixels (LED wafers) on an LED display screen, usually in millimeters (mm). It is one of the important indicators for evaluating the clarity of the display screen.
- Role in flexible LED display:
In flexible LED display, pixel pitch also plays a vital role. It directly determines the resolution and clarity of the display. Smaller pixel pitches can provide higher pixel density, making the image more delicate and clear when displayed.
- Impact on picture clarity:
The smaller the pixel pitch, the more pixels per unit area, and the more delicate the image display. This is especially important for application scenarios that need to display high-definition picture quality, such as high-definition video conferencing, digital billboards, etc.
- Impact on viewing angle:
Pixel pitch also affects the viewing angle. Generally speaking, a smaller pixel pitch means a better viewing angle, and the audience can get good visual effects from all angles.
- Impact on cost:
The smaller the pixel pitch, the higher the production cost. A smaller pixel pitch requires a more sophisticated manufacturing process and higher quality materials, which increases production costs and prices. Therefore, when choosing a flexible LED display, you need to choose a suitable pixel pitch based on actual needs and budget.
2. Key factors in selecting pixel pitch of flexible LED display
y is installed near and the audience is close, then the pixel pitch must be smaller; otherwise, the image will look blurry.
If the display is installed far away and the audience is far away, then the pixel pitch can be larger, which can meet the viewing needs and save costs.
Viewing angles is also a big problem. Flexible LED displays have a large viewing angle, but once the angle changes, the image quality may be affected.
Therefore, when choosing pixel pitch, you must ensure that the image remains clear from any angle. Generally speaking, a smaller pixel pitch will improve the uniformity and consistency of the image, and the viewing effect will be better.
3). دقة and fineness
High resolution is a highlight of flexible LED displays. The higher the resolution, the more pixels per unit area, and the image looks more fine and clear.
Especially for places where high-quality images need to be displayed, such as art exhibitions and high-end conferences, high resolution is essential.
Pixel pitch and resolution are closely related. The smaller the pixel pitch, the higher the resolution and the finer the image display. Therefore, when choosing the pixel pitch, you have to see how high the resolution and how fine the image is required.
For example, indoor high-definition display screens generally have to choose a smaller pixel pitch, such as P1.25 and P1.56, so that the image looks fine and clear enough.
Of course, it does not mean that the smaller the pixel pitch, the better. It must be selected according to actual needs, both to meet viewing needs and to consider costs. After all, if the pixel pitch is small, the cost will go up.
4). Cost and budget
Speaking of cost, that is a big problem. The smaller the pixel pitch, the more sophisticated the manufacturing process, the better the materials are, and the higher the cost. Therefore, when choosing the pixel pitch, you have to see how much of your budget you have and whether you can accept the cost.
In fact, choosing the pixel pitch is like finding a balance between cost and display effect. On the one hand, we must ensure that the display screen can meet the viewing needs and the image looks clear; on the other hand, we must consider budget constraints and not spend too much money.
Therefore, when choosing pixel pitch, we must comprehensively consider multiple factors such as application scenarios, viewing distance, resolution, fineness, and cost to find the most cost-effective solution.
For example, if the budget is limited, you can consider choosing a display screen with a moderate pixel pitch, such as P2 and P2.5. These displays can not only meet basic viewing needs but also control costs.
At the same time, you can also think of other ways to save money, such as optimizing the display screen design and reducing the installation difficulty. In short, when choosing pixel pitch, you must consider various factors comprehensively to choose the most suitable solution.
3. Pixel pitch selection in different application scenarios
In the application of flexible LED display screens, the choice of pixel pitch is crucial, as it is directly related to the quality of the display effect.
The following will discuss the choice of pixel pitch in detail for three different application scenarios: indoor curved display walls, outdoor wavy billboards, and spherical or zigzag stage backgrounds.
1). Indoor curved display wall
Due to its unique curved design, indoor curved display wall has special requirements for pixel pitch. The curved display wall needs to ensure that the image can be displayed continuously and smoothly on the curved surface to avoid image distortion or breakage.
In addition, since the indoor viewing distance is relatively close, the audience has higher requirements for the fineness and clarity of the image.
For indoor curved display walls, it is usually recommended to choose a display screen with a smaller pixel pitch to ensure the fineness and clarity of the image. Generally speaking, a display screen with a pixel pitch between 1mm and 3mm is more suitable for indoor curved display walls.
For example, display screens with pixel pitches such as P1.25, P1.56, P1.8, P2, and P2.5 are all good choices. These displays can not only provide high-resolution images but also ensure that the image can be displayed continuously and smoothly on the curved surface.
2). Outdoor wavy billboards
Outdoor wavy billboards are usually installed at a longer viewing distance, such as on the street, beside the highway, etc. Therefore, the requirements for pixel pitch are relatively low, but it is still necessary to ensure that the image is clearly visible at a long distance.
In addition, due to the complex and changeable outdoor environment, billboards need to have good weather resistance and stability.
When choosing the pixel pitch of outdoor wavy billboards, in addition to considering the viewing distance, the impact of weather and environmental factors on the display screen must also be considered.
For example, direct sunlight, rain erosion, high temperature, high humidity, and other environmental factors may affect the performance of the display screen. Therefore, it is recommended that you choose a display screen with moderate pixel pitch, good weather resistance, and stability.
Generally speaking, a display screen with a pixel pitch between 4mm and 10mm is more suitable for outdoor wavy billboards. At the same time, it is also necessary to ensure that the display screen is waterproof, dustproof, UV protected, and has other characteristics to cope with harsh outdoor environments.
3). Spherical or zigzag منصة background
Spherical or zigzag stage backgrounds pose extremely high challenges to pixel pitch and display effects.
Due to the complex and changeable shape of the stage background, it is necessary to ensure that the image can be displayed continuously and smoothly on the curved surface to avoid image distortion or breakage.
In addition, the stage background needs to have good dynamic effects and visual impact to attract the audience’s attention.
When choosing the pixel pitch of a spherical or zigzag stage background, the following technical factors need to be considered:
- Resolution and fineness:
Since the stage background needs to display high-quality images and video content, it is necessary to choose a display screen with high resolution and high fineness. Generally speaking, a display screen with a pixel pitch between 1mm and 3mm is more suitable for a spherical or zigzag stage background.
- Plasticity and flexibility:
The shape of a spherical or zigzag stage background is complex and changeable, requiring the display screen to have good plasticity and flexibility. Therefore, it is recommended to choose a flexible LED display screen to adapt to stage backgrounds of different shapes and curvatures.
- سطوع والتباين:
The stage background needs to have good brightness and contrast to ensure that the image is still clearly visible under strong light. Therefore, when choosing a display screen, you need to pay attention to its brightness and contrast indicators.
- الاستقرار والموثوقية:
As an important part of the performance, the stage background needs to ensure that the display screen has stability and reliability. Therefore, when choosing a display screen, you need to pay attention to its production process, quality control, and after-sales service.
4. Tips and suggestions for selecting pixel pitch of flexible LED display screen
Choosing the pixel pitch of a flexible LED display screen is actually like choosing a piece of clothing that fits you well. You have to tailor it to your body to find the most suitable one. Next, I will share some practical tips and suggestions to help you easily choose the pixel pitch.
1). Measurement and calculation
First, you have to measure it. How do we measure the curvature? Take a rope and bend it against the screen, then use a ruler to measure the distance between the two ends of the rope, and you can roughly calculate the curvature.
Don’t forget to measure the viewing distance; either a laser rangefinder or a tape measure will do; you need to know how many meters the audience is farthest and closest to the screen.
After measuring, you have to calculate. Don’t get a headache when you hear about calculation; it’s actually quite simple. There is a rule of thumb: if you watch indoors, choose a small pixel pitch, about 1 to 3 mm, if the distance is close.
If you watch outdoors or at a distance, choose a larger one, between 4 and 10 mm. Of course, if you want to be more precise, you can also use a formula: pixel pitch equals viewing distance divided by the number of pixels per meter you want.
However, this is just a reference, and you have to consider it comprehensively when you actually choose.
2). Sample testing and evaluation
Don’t rush to place an order; try the sample first. Ask the supplier to get a few screens with different pixel pitches, put them in a place similar to the actual environment, and see how the display effect is. Is the image clear? Is it delicate? Is it uniform? You will know after trying it.
After trying it, you may find that the pixel pitch you selected before is not suitable. It doesn’t matter, just adjust it. If the image is blurry or grainy, then choose a smaller pixel pitch.
If the cost is too high or the installation is too difficult, then consider a slightly larger one. In short, don’t be stubborn; be flexible.
