As its unique display technology, it differs from ordinary liquid crystal displays in that it improves the arrangement structure of liquid crystal molecules and can be placed horizontally and vertically on the ceiling. High brightness, high definition (1080P), long lifespan, stable operation, and low maintenance costs.

What are the advantages of DID over DLP and PDP?

DLP rear projection technology has a large volume and weight, and its key technical indicators are far inferior to LCD and plasma. Long term uninterrupted operation will accelerate the aging of DLP rear projection bulbs. Due to its lifespan of only a few thousand hours, if it runs 24 hours a day, it will take several months to replace the rear projection bulbs. Plasma is not suitable for displaying static monitoring images for a long time due to its high power consumption and heat generation, as well as serious burns. Moreover, after splicing, the overall temperature rise of the device is higher, making it easy for the equipment to burn out. LCD stands out among flat panel display technologies due to its advantages such as thin thickness, light weight, low energy consumption, long lifespan, and no radiation, as well as its excellent performance in various key performance indicators. It has become the mainstream of development and has a promising future.

Can DID LCD achieve seamless splicing?

The currently narrowest LCD panel with a border is the 46 inch ultra narrow edge DID LCD panel launched by Samsung LCD splicing screen in 2009. The upper border is 2.4mm wide and the lower border is 4.3mm wide, with a theoretical physical seam of 6.7mm. The actual minimum physical seam can be achieved at 7.3mm. The seamless LCD splicing screen currently on the market refers to the DID LCD splicing screen with a seam of 7.3mm.

What is LED backlight and how does it differ from traditional CCFL backlight?

The LCD material itself does not emit light and requires the light source on the back of the LCD panel to provide light support. LED backlight is the replacement of traditional CCFL backlight sources with LEDs (light emitting diodes, usually white light). It is divided into two types: dot matrix (also known as direct type) and side light type. LED backlit LCD screens have a wider color gamut, higher brightness, longer lifespan, and are more environmentally friendly than traditional CCFL screens.

5. What is Full HD? How to distinguish whether the LCD screen has HD full HD display function?

FullHD stands for Full High Definition, which refers to a display screen that can fully display 1920 × 1080 pixels or achieve a physical resolution of 1920 * 1080. HD stands for High Definition. According to the "Digital TV Reception Equipment - Display Standard" formulated by the Ministry of Information Industry, any TV with a horizontal and vertical clarity of 720 TV lines or above can be considered a high-definition TV. FullHD is currently the top of the line high-definition format, with both horizontal and vertical clarity required to reach 1080P or above, a physical resolution of 1920 × 1080, and the ability to fully display 6.22 million pixels of top-notch high-definition picture quality. So there is a fundamental difference in the clarity of the image display between the two.

6. Which LCD splicing screens can be directly used outdoors?

LCD screens used in outdoor environments should not only have high brightness and clear display under high light conditions, but also have special temperature and humidity control functions that can adapt to the temperature and humidity of different seasons and times outdoors. And it is designed with functions such as windproof, rainproof, dust-proof, scratch resistant, explosion-proof, and UV resistant. It can still be unmanned in harsh outdoor environments, ensuring safety and stability.

What is the seam size of the LCD splicing screen? Can it be pieced together in any quantity?

Different specificationsLCD splicing screenIt has different splicing gaps, with the narrowest physical splicing gap currently being 7.3mm and a unit size of 46 inches. The number of rows and columns can be selected according to the required display area for any number of splicing.
