The following is a case study of the new technology products released at our Ya Xunda Expo, detailing the five major advantages of LCD splicing screens:
1, long life. Liquid crystal is the longest-life display device, and its own life is very long. Even the shortest part of the backlight is up to 50,000 hours. My company's independent innovation technology - automatic refresh frequency technology, to a great extent to eliminate liquid crystal molecules in the static state of the screen burns, so that the whole machine life extension by 30%. And even if used for more than this long time, it will only affect its brightness, just replace the backlight, you can restore the original bright colors. This is a fundamental difference from the rear projection. The lifetime of LCD backlights is ten times longer than that of rear-projection bulbs, and their advantages and disadvantages are self-evident.
2, large viewing angle. For the early LCD products, the viewing angle was once a big problem restricting the development of LCD. However, with the continuous progress of LCD technology, this problem has been completely resolved. The LED LCD screen used by our company's new products can achieve a double viewing angle of 178 degrees or more and has reached the absolute viewing angle.
3, high resolution, bright screen. The dot pitch of the liquid crystal is much smaller than the plasma, and the physical resolution can easily reach and exceed the high definition standard. The brightness and contrast of the liquid crystal are very high, and the color is bright and bright. The liquid crystal splicing technology achieves a pure flat display with no curvature, and the image is stable without flicker. .
4, ultra-thin and lightweight. The liquid crystal has the characteristics of thin thickness and light weight, and can be easily assembled and installed. The 40-inch special LCD screen weighs only 12.5KG and its thickness is less than 10cm. This is unmatched by other display devices.
5, low power consumption, low heat. Liquid crystal display devices, low power, low heat has always been praised by people. Small-size LCD screen power is not more than 35W, LCD screen more than 40 inches, its power is only about 150W, only about one-third to one-fourth of the plasma. My company's newly-released auto-adjusting backlight brightness technology reduces the operating power consumption by 35% and the standby power by 0.5W by adjusting the backlight brightness in different environments.
The most important thing is that although the backlights of liquid crystal products currently use cathode vacuum tubes (CCFL), the filaments and headers at both ends of the lamp tube limit the size of the liquid crystal panel. The frame of the DID LCD screen currently used for the screen is still there. The width of 4mm-10mm, so the slightly larger stitching seam is the only disadvantage of the LCD splicing curtain wall, but with the input of LED backlight technology, this defect will be significantly improved.
Using advanced hot-dip galvanized material , precision roll forming production process, polyurethane foam that free of hydrofluorocarbon inside door, light weight, high strength, appearance nice. The doors have advantages of tamper anti-theft , noise isolation thermal insulation and corrosion resistance;the doors are widely used in shops, garages, houses, supermarkets, warehouses and industrial plants,etc.
Depending on the characteristics of the buildings,we can choose interior, exterior and intermediate three different installation ways, doors stay in the upper part of door after rolling up , this could save garage space, and also could keep the garage clean and beautiful by prevent the mud, rain and snow ,etc going into the garage.
