1, LED display tube core brand and performance
For the LED display, usually the construction side in the list of programs for customers, also will write the display equipment configuration and so on. This includes the core of the brand, size, and related products. For today''s tubes in the market, although the function may not be much. But there is a big difference in the price of different brands. High grade LED display, people generally choose to use the CREE (CREE) core, the stability of the core, anti-static, anti-oxidation, corrosion resistance and so on are very excellent. As for the tube core Nichia, a small Japanese things we don''t need to buy Chinese. A good point of the tube core domestic Taiwan Jingyuan, Guang Lei is also good, but the second is Hangzhou, Xiamen, Wuhan three Silan Huacan die, and die of other brand of homebred but quality is too unstable, so the product prices in this area will vary to nearly thousands of dollars money is the price of one square meter. So, when you know the solution, look at the configuration. The brand characteristics, we also want to carefully ponder. In addition to brands, we often think about the performance of the equipment. For the LED tube wavelength, brightness, or display angle, etc.. Some engineering chambers tell you that the tubes are either positive or partial waves, and therefore prices vary.
2, the brightness of the display
Why do you talk about the brightness of the LED display? Because there are a lot of consumers in this regard is easily deceived by unscrupulous contractors. In order to induce customers to use their own products, some engineers often increase the brightness greatly. Such a device might look pretty good at the time. And let you think he gave you the price is cheap and good quality. But after one or two years of use, the brightness promised was almost extinct. By that time, our LED screen always appears from time to time, that''s the problem. We regret that it is too late.
After all, currently on the market do too much LED display person, which refers to the brightness of the LED display screen, and is often the most vulnerable places illegal profiteers. After all, this has a very important proportion in the cost of display. So, on the condition that it is recommended that the user or before you choose a few to compare the sample screen, and then make the purchase of which decision.
3 、 driving mode of LED display screen
In the whole system of the LED display, the price of the display drive is only a small part, about eight percent to fifteen percent. However, because the types of driving accessories are becoming more and more abundant, they also give some people opportunities to do their own hands and feet. Therefore, although the driving mode is less, but it is also the place we can not ignore. The identification of driving mode can be recognized from these two aspects, one is scanning mode, and the other is the lamp board design of the equipment. In the scanning mode, dynamic scanning and static scan points in static scanning and divided into real pixel LED display is a LED display three RGB LEDs only one pixel imaging in use. The virtual pixel is the use of software control algorithm to control the light tube, and led to participate in the imaging of a plurality of adjacent pixels, the virtual screen is great resolution with less lamp, can make the pixel resolution of LED display increased 4 times. They also have a big price difference between the two. And these are places that can easily be ignored and deliberately confused.
And for the design of the lamp board, is the lamp drive separation or lamp drive one, is double PCB or four layer PCB3 drive IC brand is also need our focus on the place. After all, there are as many as more than 10 kinds of related products on the market today. If you want to cut corners, how difficult is it?
4, display service and structure after sale
Speaking of this after-sale service, Xiao Bian has to say loudly that there are too many cheats in the society. After sales service pit father! Why am I making such a fuss? Some unscrupulous profiteers in order to win the project, how many years warranty commitment to consumers, but we take screen problem, basically is to make our own hands to display debugging, but remove the trouble of LED display calculation content is high, if we say that we are not here, traffickers said, you have a bad place to help you send manufacturers maintenance, so a return to the time in the past half a month, a screen or not fixed. After the sale, it is strongly recommended that consumers and manufacturers contract to indicate the form and response time of after-sales service. In the case of the equipment, some of the equipment is simple box, some seemingly simple but waterproof box. And for different types, their difference is mainly reflected in whether the back door and the thickness of the box. In addition, the choice of the structure, in the end is the choice of modular splicing, or the lamp board is directly fixed on the box board, there are many differences. If it''s modular, it''s more convenient to repair because it''s easier to disassemble.
