LED monitors and LCD monitors are often compared. Which is better? To understand this question, first of all, you have to understand how LED monitors and LCD monitors work.

LED display is a kind of display screen which is used to display text, graphics, images, animation, market, video, video signals and other information by controlling the display mode of semiconductor light-emitting diodes. Through the appropriate connection of the light emitting diode chip (including series and parallel) and the appropriate optical structure. The luminous segment or luminous point of the luminous display can be formed. These luminous segments or points can form digital tubes, symbol tubes, meter tubes, matrix tubes, level display tubes, and so on.

LCD display is a kind of active matrix liquid crystal display driven by thin film transistor (TFT). It mainly uses current to stimulate liquid crystal molecules to produce points, lines, surfaces and back lamps to form a picture. The working principle of LCD display is as follows: under the action of electric field, the light transmittance of external light source is changed (modulated) by changing the arrangement direction of liquid crystal molecules, and the electro-optical transformation is completed, and then the color redisplay in time domain and space domain is completed by using different excitations of R, G, B trichromatic signals and red, green and blue trichromatic filter films.

 
                                                          So, which is better, LED monitor or LCD monitor?                                                            

First, picture quality.                 

LED display screen has higher refresh rate, sharpness and brightness than LCD display screen, and has more advantages than LCD display screen. It is worth noting that the TV industry has launched a new "Ultra HD Premium" logo, and LCD TV has been awarded this logo. In other words, LCD display technology has the ability to present state-of-the-art high-definition image quality.

Second, energy consumption.

As far as its LED light source is concerned, LED display screen is an energy-saving and environment-friendly product. Semiconductor light-emitting diode (LED) is an extremely energy-saving light source with a wide range of applications at the current level of technology. In fact, LCD display has fully used LED backlight, compared with the traditional CCFL backlight, LED backlight has obvious advantages, such as low driving voltage, long life, small size, light weight, good color level performance, more uniform brightness, more environmental protection, impact resistance.

Third, contrast.                          

The contrast of a high-quality LED display screen can reach 3000 1, and the contrast of a good quality LCD panel can basically reach 1000 1. LCD TVs typically show much higher dynamic contrast, because it refers to the TV's ability to adjust the level of backlight according to the content of the screen, not the actual contrast.

Fourth, splicing function.        

LED display screen can achieve seamless splicing of large screens, and according to the needs of the project, splicing various shapes of the display screen. When the LCD is spliced together, the gap between each LCD module appears to be more obvious, and the display effect is not satisfactory.

Fifth, cost.                                 

The pricing method of LED display is squared, which is generally distinguished according to the size of the dot spacing. The higher the dot spacing is, the cheaper the price is. LCD monitors are priced according to the size and type of the screen itself. Compared with LED monitors, LCD monitors are cheaper.

Sixth, application.                    

LED displays are mainly used in outdoor large advertising screens, while LCD displays should be more extensive, ranging from palmtop tablets to large advertising screens. LCD displays can be seen almost everywhere in industrial, commercial and medical industries.

After reading the above comparison, perhaps everyone has a different view. Because everyone has different needs, this requires different solutions. For customized LCD display solutions, please contact Xianheng Technology, we are professional.
