Is LED better than LCD?

Both LED display and LCD display are relatively common video displays on the market,So are led better than lcd?LCD displays are mostly used in TVs, which are often referred to as LCD TVs, while LEDs are more used in video display of commercial advertisements. Match with the background of the stage performance. To judge which is better between LED display and LCD display, we must first understand what is LED display and LCD display.

The concept of LED display and LCD display

LED is the English abbreviation of Light Emitting Diode. LED display is composed of many small LED module panels. Each LED module panel, also called LED display module, is composed of many LED modules. The dot pixel matrix is ​​arranged, and the distance of each LED dot pixel is called the dot pitch.

Under normal circumstances, the dot pitch below P5 (including P5) is used indoors, and the dot pitch below P2 is called a small pitch LED display, such as P2, P1.875, P1.667, P1.583, used in The indoor viewing distance is relatively close; while the pixel pitch is above P5, it is often used outdoors. P8, P10, P16 and other dot pitches are the specifications of LED displays that are 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 the 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.

LED display or LCD display, which is better?

1). In terms of 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.

2). Energy consumption, LED display is an energy-saving and environmentally friendly product in terms of its LED light source. 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 LED display is LCD display. 10 times the screen, that is to say, under the same configuration conditions, LCD consumes 10 times more power than LED.

3). Viewing angle, LED display can achieve a relatively large viewing angle, 165° viewing angle, 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.

4). Contrast ratio, high-quality LED display, the contrast ratio can reach 3000:1, while the contrast ratio of high-quality LCD display under the same configuration condition is only about 350:1, that is to say, the LED display is higher than the LCD display. The screen image restoration ability is nearly 10 times stronger.

5). Display splicing, LED display can realize seamless splicing of large screens, and can splicing various shapes of displays according to the needs of the project, such as LED special-shaped screen, LED cube screen, arc, circle, column shapes 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.

6). The scope of use, the LED display has a wide range of use, it can be used for advertising video promotion, indoor and outdoor stage performances, on-site video presentations, video speeches at business conferences, video promotions in stadiums and backgrounds of major evening parties match and so on.

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.

In addition to the above advantages, LED display has more advantages than LCD display in terms of service life, display color, exquisite appearance and production process. Which is better, LED display or LCD display? From the above comparison, we have already got the answer, obviously LED display is much better than LCD display.

Compared with the LED display, the only advantage of the LCD display is that it is cheaper and cheaper than the LED display, which is the main reason why the LCD display cannot be completely replaced by the LED display.
