Differences between LCD splicing screen and small-pitch LED screen

Differences between LCD splicing screen and small-pitch LED screen

The LCD splicing screen can be used alone as a monitor or can be spliced into a super large screen. According to different usage requirements, various large-screen functions can be realized that can be made larger or smaller: single-screen split display, single-screen independent display, any combination display, full-screen LCD splicing, double-splicing LCD splicing, vertical screen display, image border Optional compensation or masking, supports digital signal roaming, zooming and stretching, cross-screen display, setting and running of various display plans, and real-time processing of full HD signals.
Small-pitch LED screen refers to indoor LED screen with LED point spacing of P2.5 and below, mainly including P2.5, P2.083, P1.923, P1.8, P1.667, P1.5, and P1. 25. P1.0 and other LED screen products.
So what are the specific differences between LCD splicing screens and small-pitch LED screen?

1. Differences in technology

Display principle

Small-pitch LED screen is self-luminous, and LCD splicing screens are backlight + liquid crystal imaging. From the perspective of physical seams, small-pitch LED screen has no seams, and LCD splicing screens have a gap of 0.88-3.5mm.

Color saturation

Small-pitch LED screen has higher color reproduction and more vivid colors.

Gray scale

The small-pitch LED screen is 16 bits, and the LCD splicing screen is 8 bits.

Power consumption

Small-pitch LED screen and LCD splicing screen are both high-efficiency and energy-saving products.


2. The difference in product thickness

LCD splicing screen is much thicker than small-pitch LED screen , which have now reached ultra-thin designs.
The small-pitch LED screen all-in-one machine has a minimalist design and an ultra-narrow frame of 3mm; it has an ultra-thin structure and the thickness of the whole machine is only 38.5mm.

3. Cost difference

The main costs are currently 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

LCD splicing screens are more affordable and have more advantages. Maintenance costs;

Maintenance cost

For small-pitch LEDs, only broken modules need to be repaired separately, which does not affect use and has low maintenance costs; LCD splicing screens: faults generally cannot be repaired, and the full screen can only be replaced;

Service life

The normal use life of the small-pitch LED screen is 100,000 hours, and the normal service life of the LCD splicing screen is 40,000 hours.


For LCD panels and LED panels, users don’t have to worry about insufficient brightness. However, high-brightness small-pitch LED screen faces the problem of excessive brightness. Before choosing an LED screen, users must consider whether it matches the display environment. According to user needs, LCD display manufacturers have developed LCD displays with brightness of 500cd/m2 and 700cd/m2, making the use of 55-layer LCD displays greatly exceed that of LED displays.

LED splicing screens have made breakthroughs in recent years, but they still cannot compete with LCD screens. Nowadays, the resolution of LCD monitors is generally 1920*1080p, and some LCD monitors can already display 4K signals. In order to achieve higher resolution, it is necessary to increase the geometric base, reduce the pixel distance by 50%, and increase the density of the base plate by 4 times to ensure the stability of the design. Although there are bottlenecks at 1.0, 0.8 and 0.6, what really leads to a large number of applications is products like 3.0/2.5. Obviously, that doesn’t mean clearer users can pass it. In fact, many users only use splicing screens with normal resolutions. The higher the level of clarity, the more difficult it is to overcome the technique and the higher the cost of the equipment. The result is that many users do not choose high resolution.

4. Differences in display functions

Although LED and LCD displays are mosaic screen display products, most of which are determined by the display control device, but there are also strong or weak display functions that are completely different. For example, the LED display mainly has a large display screen, and the window can be realized by processor roaming and multi-screen display at the same time, so it is more suitable in the case of signal sources.
The LCD splicing screen can be spliced into a large-screen display, and can also support single-screen display signals, single-screen splicing of multi-channel signals, cross-screen splicing and roaming display effects, etc., so that multiple signal sources from a single signal source can be displayed at the same time and decoded. show.

5. Differences in maintenance methods

Most LCD splicing screens adopt rear maintenance methods – leaving access channels behind. It is necessary to leave sufficient maintenance access on the back of the screen, which generally requires a width of about 70 centimeters to 1 meter. This requires high construction space and will compress the visual space to a certain extent.
The small-pitch LED display all-in-one machine has full front maintenance, supports hot swapping, and does not need to reserve a maintenance channel. It is convenient for maintenance, saves space, and has full front maintenance.

6. Differences in usage environment

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

The small-pitch LED display can be used indoors or installed outdoors. This is also determined by its special structure. It can be used in outdoor environments after adding waterproof measures.
