LED small pitch display VS LCD splicing screen

To understand the difference between LED small pitch display and LCD display, we first need to understand what is LED display and LCD display.

Basic overview of LED display and LCD display

LED is the English abbreviation of semiconductor light-emitting diode. The LED display is composed of many small LED module panels. Each LED module panel, also called LED display module, is composed of many LED lamp beads. The distance from the center point of each LED lamp bead to the center point of the adjacent LED lamp bead is called the point spacing.
Under normal circumstances, the P point is relatively small, for example, those below P5 (including P5) are used indoors, and those with a dot pitch below P2 are called small-pitch LED displays, which are used in places where the indoor viewing distance is relatively close; If the point spacing is above P5, it is often used outdoors.

LCD is the abbreviation of liquid crystal display, which is composed of a certain number of color or black and white pixels, placed in front of a light source or reflector. Liquid crystal is a special substance between solid and liquid. It is an organic compound. It is liquid in normal state, but its molecular arrangement is as regular as that of solid crystal, so it is named liquid crystal.
The main working principle of the LCD display is to stimulate the liquid crystal molecules to generate dots, lines and surfaces with the back light tube to form a picture.

What is the difference between LED display and LCD display?

Display splicing

The LED display can realize seamless splicing of large screens, and can be spliced ​​with various shapes of displays according to the needs of the project, such as LED special-shaped screens, LED cube screens, arcs, circles, columns and polygons, etc.
When the LCD is spliced ​​together, there will be a relatively large gap between each LCD module. If the viewing distance is far, you will not feel anything, but if the viewing distance is a little closer, the gap on the large LCD screen will appear more obvious. The effect is greatly reduced, and the LCD display is difficult to be spliced ​​into other video displays of various shapes, which is also the advantage of the LED display over the LCD display.

Scope of use
LED display is widely used, it can be used for advertising video publicity, indoor and outdoor stage performances, on-site video presentations, video speeches at business conferences, video publicity in stadiums and background collocation of major parties, etc.
The LCD display has a relatively single use range, and is generally used in advertisements with a relatively long viewing distance, while more LCD displays are used in TV display, which is often referred to as LCD TV.

Contrast
The high-quality LED display has a contrast ratio of up to 3000:1, while the contrast ratio of the high-quality LCD display under the same configuration conditions is only about 350:1, that is to say, the LED display has better image restoration ability than the LCD display. nearly 10 times.

Clarity and Brightness

The refresh rate of the LED display is much higher than that of the LCD display, and the clarity and brightness are more advantageous than the LCD display. And the LED display screen can still be displayed clearly under the strong light of direct sunlight, and the screen display brightness will be automatically adjusted according to the brightness of the outdoor environment to achieve excellent video display effect.

energy consumption
The LED display screen is an energy-saving and environmentally friendly product in terms of its LED light source. The semiconductor light-emitting diode LED is an extremely energy-saving and widely used light-emitting source at the current technical level. The energy-saving effect of the LED display screen is 10 times that of the LCD display. That is to say, under the conditions of the same configuration, LCD consumes 10 times more power than LED.

Viewing angle
The LED display can achieve a relatively large viewing angle, with a viewing angle of 165°, the video display is still clear. The viewing angle of LCD is very limited. If the viewing angle is slightly larger, it will not be clear and the video will become blurred.

From the above comparison, we have already got the answer, obviously LED display is much better than LCD display. However, the price of the LED display is much higher than that of the LCD, which is the main reason why the LCD display cannot be completely replaced by the LED display.

What is the current market environment for LED transparent screens?

LED transparent screen is a new type of transparent display product created by using human vision principles. The structure of the light bar is similar to blinds, and the lamp beads are evenly distributed on the light bar in a dot matrix. It is generally installed and indoors without changing the building space and appearance. It has the characteristics of high transparency, high brightness, and colorful colors. So,what is the current market environment for LED transparent screens? Due to its large-area display characteristics, LED transparent screens generally adopt a modular design, which can be assembled into a giant screen by

What are the energy saving and environmental protection methods for LED transparent screen?

If a large transparent LED screen is installed, for example, some shopping malls have a large area. When a huge transparent LED screen is erected from top to bottom, it may reach dozens of square meters. The large transparent display consumes The power is naturally very large. From the perspective of power consumption, although the luminescent materials used in the LED display itself are energy-saving, some of them need to be used in occasions with a large display area. Due to long-term use, the overall power consumption is still relatively large. The required brightness will be relatively high. Under the

What details should we pay attention to when building an interactive floor tile screen?

The interactive floor tile screen is slightly different from the traditional LED display screen. The traditional LED display screen is generally erected in front of people through hoisting, inlay and other methods. The interactive tile screen is laid horizontally on the ground. People can step on it to dance or watch beautiful pictures, and can produce an interactive effect with the human body by cooperating with external radar or infrared. Therefore, it is very suitable to be placed in some tourist attractions or video game cities. So, what details do we need to pay attention to when building such an
