It seems like a rare object found in science fiction movies. At first glance, it looks like a transparent screen. In fact, it has quietly entered many places such as shopping malls, exhibition halls, and high-end retail stores. Its biggest feature is that it can display image information while maintaining transparency and visibility. In the past, people only heard of OLED transparent screens, but now, LCDs can also achieve the function of transparent display.
Previously, transparent screens were quite mysterious to the public, as if they existed only in the far-reaching science fiction imagination. However, now, it has actually appeared in various commercial spaces around us. It breaks through the limitations of traditional screens and presents information to people in a unique way. From the initial awareness of only OLED transparent screens to the rise of liquid crystal transparent display technology, this field continues to develop and progress, bringing us more novel visual experiences.
Is the display effect of the transparent screen really clear?
Many people are worried that the brightness of transparent screens is insufficient and they cannot see the display content clearly in bright shopping malls. In fact, the brightness of current transparent screen products can usually reach more than 1,000 nits, and some products can even reach 3,000 nits. Under strong light conditions during the day, black characters on a white background are still clearly legible.
The key to the quality of the display lies in whether a good balance can be achieved between light transmittance and pixel density. The scene on the back of a module with a higher light transmittance can be displayed more clearly, but the graininess of the picture may be relatively focused. Screens with high pixel density have a delicate texture, but the background will look darker. Different scenes require different trade-offs. For example, the jewelry counter scene places more emphasis on transparency, while the information guidance screen prioritizes clarity.
There is a range of perspectives when it comes to details that are easily overlooked. For some transparent screens, when viewed from the side, the color will be significantly darker, which will affect the effect of long-distance viewing. During the purchase process, it is best to measure the left and right and up and down viewing angles to ensure that all customers can see the content clearly.
Why are the prices of transparent screens so different?
In the market, the price range of transparent screens is quite large. The price of one piece ranges from a few thousand yuan to tens of thousands of yuan, and the main differences among them are concentrated in three aspects.
The first is the luminescence technology. The OLED transparent screen has its own self-luminous characteristics. The black color is particularly pure and the visual effect is quite good. However, it is very costly and has a relatively short service life. Secondly, we should look at the LED transparent screen. It has relatively high brightness and good weather resistance. With this characteristic, it can also perform well in outdoor environments. However, its pixel pitch is relatively small. Finally, there is the LCD transparent screen, which has a high cost performance, but requires certain support from the backlight and has certain limitations in terms of light transmittance.
The first is the second point, which is related to the module size and the splicing method. For standard-sized modules, their respective prices are transparent to a certain extent. However, once customized sizes are involved and special-shaped cutting is performed, the additional cost will double the cost accordingly.
Some suppliers integrate the driver board and power supply into the frame, which makes installation very simple, but the price is much more expensive. If you purchase external equipment separately, although you can save costs, it will increase the difficulty of debugging.
First, the price of products from small workshops is half the price. However, once a few lamp beads are broken, the whole machine may have to be replaced, and the overall cost is actually higher. Secondly, the products of major manufacturers have brand premiums and after-sales services. They have complete color calibration and aging test reports, and when problems arise, someone will come to repair them.
For those customers with limited budget, it is recommended to first find out what the lighting conditions of the installation environment are and what the approximate viewing distance is, and then choose an LCD solution with suitable light transmittance and resolution. For exhibition halls that pursue the ultimate experience, using OLED transparent screens will be more worry-free. No matter which solution you finally choose, be sure to ask clearly about the warranty period and repair response time to avoid headaches during later maintenance.
