Large screen splicing has always been one of the hot technologies and topics. The following four types of large-screen splicing are the most representative. Today, I will make a simple analysis and comparison of their advantages and disadvantages.
The mainstream of display products on the market has LED display, LCD display, etc., they represent the latest technology, including screen splicing technology is undoubtedly one of the most popular topic, the following four types of screen splicing technology is the most representative, the following DE embellish self have their advantages and disadvantages of doing a simple comparison, convenient friends understand.
By controlling the display mode of semiconductor light-emitting diode, the text, picture, animation, video and content are displayed through red, blue, white and green LED lights on and off.
Key points: bigger, thinner and more stable
Advantages: long life, spherical display, strong and durable, suitable for outdoor application
Disadvantages: the pixel points are sometimes obvious, the industry‘s most delicate LED point spacing is 1mm, not easy to miniaturize.
The liquid crystal itself is not luminescent, it glows by the backlight tube, so the LCD depends on the backlight tube.
Key points: higher and thinner
Advantages: high resolution, thin thickness and long life
Disadvantages: delay problem, with obvious gap
Projection DLP splicing
Digital optical processing, that is to say, the technology will first image signal through digital processing, and then the light projected out.
Key points: bigger and higher
Pros: seamless stitching, maximum display area, support spherical display
Disadvantages: bulb life problem, must have projection distance
Plasma PDP splicing
Ion display is a kind of display device which makes light by gas discharge.
Key points: thinner
Pros: high brightness, short response time
Conclusion: the advantages and disadvantages of the above four types of large-screen are different, which is not to say that which type of screen is bad. They are suitable for use in their respective fields. Among them, LED display is a key product in the large-screen field, which has a broad prospect in outdoor advertising, stage dancing and other fields.
