What are the differences between small-pitch LED display and DLP and LCD splicing?

May 14,2021| LED Knowledge

Small-pitch LED displays, DLP, and LCD are very common high-definition displays in daily life. Because the display effect and appearance alone cannot see any effective information, many people do not know the difference between them. Next, let us take a closer look.

Different display

Small spacing: Small spacing LED screens have advantages in seams, brightness, color saturation, resolution, and flexibility of use;

DLP: DLP splicing wall has more advantages in terms of fineness of the picture and cost. This skill will constitute a head-to-head competition in high-end indoor shopping malls;

LCD splicing: LCD splicing also has advantages in terms of quotation and fineness of the screen. However, affected by factors such as quotation, at this stage, small-pitch LED screens will focus on high-end shopping malls, while LCD splicing will focus on low-end shopping malls, so the competition between the two is not very obvious;

Projection blending: The projection blending system has higher brightness and a certain price advantage, especially in terms of creative projection display. It has an irreplaceable position. Therefore, the two sides will not replace each other, and the small-pitch LED screen may pose a challenge to the blending and display of engineering projectors within a specific application scale;

Different display principles

LED display screens are divided into graphic display screens and video display screens, both of which are composed of LED matrix blocks. The graphic display screen can display Chinese characters, English text and graphics in synchronization with the computer; the video display screen is controlled by a microcomputer, and the graphics, text and images are both displayed. It can display various information in real-time, synchronized and clear information dissemination mode, and can also display two One-dimensional, three-dimensional animation, video, TV, VCD programs and live broadcasts.

DLP seamless splicing screen is based on the original LCD splicing screen through technical improvement, shielding the original physical splicing, so that the image presents a full high-definition display, there is no longer a black frame in the display, to achieve perfection Visual experience;

LCD liquid crystal uses the principle of deflection of liquid crystals under the action of voltage. The liquid crystals that make up the screen can display the three primary colors of red, green, and blue at the same point, or a point of the liquid crystal is superimposed by three points, which are arranged in a certain order, and the liquid crystals are stimulated by voltage. It can show different colors, and different proportions can show ever-changing colors.

All in all: LCD splicing screens, DLP, and small-pitch LED displays have their own advantages in the display field. Only by choosing the right products in the right environment can their unique advantages be brought into play.

With the continuous updating of LED display technology, the dot pitch of the display is getting smaller and smaller. When we actually purchase indoor small-pitch LED displays, what key points should we pay attention to in order to maximize the investment benefits while meeting the needs of use? Let's take a look.

1. "Low brightness and high gray" is the premise:

In order to ensure viewing comfort, the primary concern for users when purchasing small-pitch LED products is the brightness issue. In the traditional LED display technology, reducing the screen brightness will cause the loss of gray scale, and the loss of gray scale will directly affect the picture quality, that is, the picture is not delicate enough. Therefore, an important criterion for high-quality small-pitch LED screens is to achieve "low brightness and high gray" technical indicators.

In actual purchase, users can follow the principle of "the more brightness levels that the human eye can recognize, the better". The so-called brightness level refers to the brightness level of the image that the human eye can distinguish from the darkest black to the whitest white. , The higher the recognized brightness level, the richer the color displayed on the display screen, the greater the color potential, and the more vivid the color of the played video, and the higher the saturation.

2. When choosing the point spacing, pay attention to the balance of "effect and technology"

Compared with the traditional LED screen, the outstanding feature of the indoor small-pitch LED display is the smaller dot pitch. In practical applications, the smaller the dot pitch, the higher the pixel density, the more information capacity per unit area can be displayed at one time, and the closer the distance suitable for viewing. On the contrary, the longer the distance suitable for viewing.

When selecting the point spacing, the user should first choose according to the area of the site, followed by the installation site of the screen, the content to be displayed, and the effective viewing distance. In addition, the budget also accounts for a large part, and the prices of LEDs with different configurations are also different. Therefore, in the actual purchase, users should comprehensively consider their own cost, demand, application range and other factors.

3. When choosing the resolution, pay attention to the match with the "front-end signal transmission equipment"

The smaller the dot pitch of the indoor small-pitch LED display, the higher the resolution, and the higher the picture clarity. In actual operation, users want to build the best small-pitch LED display system. While paying attention to the resolution of the screen itself, they must also consider the combination of it with front-end signal transmission products.

At present, indoor small-pitch LED display products have a wide range of applications.

It is very popular in TV studios, power system monitoring centers, aerospace command centers, military command centers, government halls, urban monitoring centers, video conference rooms, dispatch rooms, airports, railway stations, hotels, and large and medium-sized enterprises. Every enterprise also wants to have its own display equipment.
