Smart LED screen changes with the sun and the environment

Walking in the streets of the city, a variety of billboards, advertising banners, LED displays are always visible everywhere. But do you know how the billboards and advertising banners with different characteristics and forms are actually made? What changes have occurred in the LED display quietly? On the 9th, the reporter came to the 17th Changchun Advertising and LED Lighting Expo in Changchun in 2014 to explore the production process of billboards at close range.

Advertising metal word production is roughly divided into three steps

Inkjet printing machine with a width of up to 5 meters, high-definition crystal color LED display, electronic light box, plasma cutting machine, metal word slotting machine... In the 2014 17th Changchun Advertising and LED Lighting Expo, various productions The banners and billboards of the machine and the device that displays the advertisement "gather together."

Accompanied by the "beep" sound from the machine, a metal word of about 10 cm square is completely presented between the lights and stones. The staff at the scene told the reporter that it takes about three major steps from the metal panel to the production of a qualified metal word on the billboard.

To make a metal word, first make a metal plate and a metal plate, then make a three-dimensional rim, and then polish it after welding.

In the process of production, plasma cutting machines, laser welding machines, slotting machines, edge stripping machines, etc. are all equipment that needs to be used.

"The cutting machine is used together with the grooving machine and the edging machine. The bottom plate and the surrounding of the word are cut out, and then welded together by a welding machine. It is necessary to make a high-quality re-plating and polishing, so that a metal word is completed. Said the staff.

It is understood that with the development of technology, machines with new functions are constantly being introduced. CNC plasma cutting machine, intersecting wire cutting machine, metal word edger, metal word slotting machine, laser welding machine and other equipment have realized the automation, batching and standardization of the metal word making process, solving the traditional hand-made problem. .

“Like the intersecting wire cutter, it can be cut in three-dimensional and three-dimensional rotation. It has high speed and high precision and can complete a variety of image cutting. With the laser engraving machine, Chinese characters of a few millimeters can be engraved,” one exhibitor said.

Smart LED screen changes with the sun and the environment

As an indoor and outdoor advertising display device for audio and video functions, LED large screen is becoming a trend in the development of modern advertising industry with its unique advantages. With the continuous development of technology, LED displays are becoming more and more intelligent. The imaging is more clear, and the brightness is adjusted with the intensity of the sun... A LED display dealer told reporters that with the location of the large display in Changchun City, the location is getting smaller and the price is getting lower and lower. Currently, small and medium-sized The display has gradually become the mainstream of sales.

"The current specifications are only 8 mm P8 LED outdoor display between two points, the price is very high. Previously, the P8 type display of one square meter required about 10,000 yuan, and now it is only 8,000 yuan." The exhibitor introduced that for the previous outdoor street intersection, the display screen swayed the driver and pedestrian eyes, affecting the line of sight, has been improved.

“The smart display that we sell is equipped with an intelligent software that can adjust the brightness of the display in time with the intensity of the sun and the environment at the time, so there is no blind spot, so that the eyes can easily adapt to the brightness of the display. The function of automatically adjusting the brightness, the display produced now can save 50% energy compared to the previous display." The exhibitor told reporters.

Smart pencils don't have to be constantly written

At the fair, although advertising and LED lighting are the main exhibitions, there are also some eye-catching and unique new technology items.

“Automatic core adjustment, refills, no need to press, continuous writing, no planing, low carbon and environmental protection.” A smart pencil appeared at the fair. The reporter used a smart pencil to write a few words on the paper and found that the smart pencil, in addition to the appearance of plastic material, wrote the same words as ordinary pencils, and looked more like a mechanical pencil.

According to the seller of smart pencils, the smart pencil only entered the Changchun market two months ago. The lead in the pencil uses high-density ink, which is not only tough but also wear-resistant, so it is longer than ordinary pencils and is not easy to break. . "Ordinary pencils are also used for one month. This pencil can be used for two semesters. What's more intelligent is that the lead is not only continuous, but the lead that is exposed is not automatically pressed out. It is written like a regular pencil. Use a rubber eraser to wipe it off."
