The LCD splicing screen can be used as a display alone or as a large screen. According to different use requirements, it can realize the functions of variable large and variable small screens: single-screen split display, single-screen separate display, arbitrary combination display, full-screen LCD splicing, double-screen LCD splicing, vertical screen display, image frame optional compensation or masking, support digital signal roaming, zooming and stretching, cross-screen display, setting and operation of various display plans, and real-time processing of full-HD signals.

 

Small spacing LED display refers to indoor LED display with LED point spacing of P2.5 and below, mainly including P2.5, P2.083, P1.923, P1.8, P1.667, P1.5, P1.25, P1.0 and other LED display products.

 

What are the specific differences between the LCD splicing screen and the LED display screen with small spacing? Are you interested in knowing the seven differences between indoor LED display and outdoor LED display?

1. Technical differences

Display principle

The LED display with small spacing belongs to self-illumination, and the LCD LCD splicing screen belongs to backlight+LCD imaging. From the point of view of physical seam, the LED display screen with small spacing has no seam, and the LCD LCD splicing screen gap is 0.88-3.5mm.

Color saturation

Small-spaced LED display screen has higher color restoration and brighter color.

Grayscale

The LED display screen with small spacing is 16bits, and the LCD splicing screen is 8bits.

Power consumption

Small spacing LED display screen and LCD LCD splicing screen are efficient and energy-saving products.

2. Difference of product thickness

The LCD splicing screen is much thicker than the small-space LED, and the small-space LED display has reached the ultra-thin design at present.

The small spacing LED display screen all-in-one machine is extremely simple in design, with an ultra-narrow frame of 3mm; Ultra-thin structure, the overall thickness is only 38.5mm.

3. Cost difference

At present, the main costs are divided into three parts. The first is the purchase cost, the second is the maintenance cost, and the third is the service life.

Purchase cost

The price of LCD splicing screen is new and more competitive. Maintenance costs;

Maintenance costs

The small spacing LED only needs to repair the broken module separately, which does not affect the use, and the maintenance cost is low; LCD splicing screen: generally, the fault cannot be repaired, and only the full screen can be replaced;

Service life

The normal service life of small spacing LED display screen is 100000 hours, and the normal service life of LCD splicing screen is 40000 hours.

Brightness

For LCD panel and LED panel, users need not worry about insufficient brightness. However, the high brightness and small spacing LED display screen is facing the problem of high brightness. Before selecting LED display screen, users must consider whether it matches the display environment. LCD manufacturers have developed LCD displays with brightness of 500cd/m2 and 700cd/m2 respectively according to the needs of users, making the use of 55-layer LCD display much more than that of LED display.

Resolving power

LED splicing screen has made a breakthrough in recent years, but it still cannot compete with LCD. Now the resolution of LCD is generally 1920 * 1080p, and some LCD displays can already display 4K signals. In order to achieve a higher resolution, it is necessary to increase the geometric base, reduce the pixel distance by 50%, and increase the base plate density by 4 times to ensure the stability of the design. Although there are bottlenecks at 1.0, 0.8 and 0.6, the real reason for a large number of applications is products like 3.0/2.5. Obviously, this does not mean that clearer users can use it. In fact, many users only use the splicing screen with ordinary resolution. The higher the clarity, the more difficult it is to overcome this technology and the higher the equipment cost. The result is that many users do not choose high resolution.

4. Difference of display function

Although LED and LCD displays are mosaic screen display products, most of which are determined by display control devices, there are also strong or weak, and the display functions are completely different. For example, LED display mainly displays large screen, and the window can be realized by the processor roaming and multi-screen display at the same time, so it is more suitable in the case of signal source.

The Lot splicing screen can be spliced into a large screen display, and can also support single-screen display signals, single-screen splicing multi-channel signals, cross-screen splicing and roaming display effects, so that multiple signal sources of a single signal source can be displayed at the same time and decoding display can be realized.

5. Differences in maintenance methods

Most LCD splicing screens adopt post-maintenance mode - maintenance access is reserved at the rear. It is necessary to leave enough maintenance access at the back of the screen, generally about 70cm to 1m wide, which requires high construction space and will compress the visible space to a certain extent.

Small spacing LED display all-in-one machine full front maintenance, support hot plugging, no need to reserve maintenance channels, convenient maintenance, space saving, full front maintenance.

6. Differences in use environment

The LCD splicing screen can only be used indoors because it is composed of many electronic components. Like all electronic products, it does not have waterproof characteristics, so it is suitable for use in indoor dry environment.

The small spacing LED display can be used indoors or outdoors, which is also determined by its special structure. It can be used in outdoor environment after adding waterproof measures.
