LED display

 

LED display is a flat panel display, consisting of small LED module panels, used to display text, images, videos and other information.Here is a more detailed introduction to the led display!

 

LCD


LCD (Liquid Crystal Display) is a kind of liquid crystal display, which is a flat ultra-thin display device. It consists of a certain number of color or black and white pixels and is placed in front of the light source or reflective surface.


When selecting a display screen, users want to know which is better, LCD or LED. For example, whether LCD or LED display is good, which is harmful to the eyes, and which is not harmful to the eyes. Especially in some large screen display situations that need to be used for a long time, these specific factors will directly affect our use.


Display effect


LED display screen is a display screen with diode combination, which can self emit light, and the display effect will be more fully integrated. In addition, LED display screen can also adjust the brightness, which can be adjusted in time according to different environments. LCD display screen is composed of liquid crystal, which emits light by refracting light, so its display effect is not so natural, and it also lacks in color saturation.


Resolving power


From the perspective of resolution, the LCD screen is higher, so the picture presented by the LCD screen is clearer. This is because the resolution of one screen of the LCD screen is 1920 * 1080, which belongs to the high-definition screen. The resolution of the LED screen is determined by its lamp spacing. In general, the lamp spacing is larger, which is determined by the packaging technology, so its resolution is lower, and it is not fixed according to the product specifications, In general, the LED is not as clear as the LCD screen when displaying images.


Application environment 


From the perspective of application environment adaptability, LED screen is undoubtedly better than LCD screen. Because LED screen has the characteristics of waterproof and sunscreen, and its brightness is also high, it can meet the needs of outdoor applications. It can display images normally even in rain and direct sunlight. The LCD screen can only be used in the indoor environment, because it is an electronic product. There are many electronic components inside, and water cannot be seen, otherwise it will cause a short circuit. Therefore, LED screen has more advantages in terms of environmental application.


Brightness


The brightness of LED is 3500-5500 cd/m2, and the brightness of LCD is 250-1500 cd/m2. The LCD LCD screen has low brightness and is not suitable for outdoor and indoor use with strong light. The LED screen is not limited by the strength of optical fiber.


Thickness and power consumption


In thickness, the lcd is thicker because of the existence of the backlight layer and the liquid crystal layer. And led is very easy to make mobile phones thin, which also provides the possibility for the emergence of flexible screens and folding screens in the future. In terms of power consumption, once the LCD is turned on, its entire backlight layer will also be turned on. It can only be fully turned on or off. The power consumption is high. While each pixel of led works independently, and some pixels can be lit independently, so the power consumption of led will be lower.


Summary


There are five differences between LED and LCD. The main differences are display effect, resolution, application environment, brightness, power consumption, etc.
