Okay, let’s not gossip, let me show you what happened in the LED industry last week.
Huati Technology suffered another "old enemy" two lawsuits: More than 2000 sets of LED street lights involved in patent infringement?
On the evening of July 24, Huati Technology issued an announcement stating that it had received a civil lawsuit. Guizhou Lestar Lighting Technology Co., Ltd. (hereinafter referred to as Guizhou Lestar) sued Huati Technology and other three defendants for patent infringement, involving a total amount of 3242.06. Ten thousand yuan. At the same time, Huati Technology also disclosed that it received another complaint on the same day, and the plaintiffs were both Guizhou Luxtec.
It turns out that the dispute between Guizhou Lestar and Huati Technology has been around for a long time. In recent years, the two parties have been in court. The former was an agent of Huati Technology.
The total amount of the two cases exceeds 40 million.
According to Huati Technology’s disclosure on the evening of the 24th, on July 21, it received the "Civil Complaint" and related legal documents in response to the Guiyang Intermediate People's Court. According to the "Civil Complaint", Guizhou Rexta believes The street lights installed by Kaili Economic Development Zone Urban and Rural Administration Bureau, Jiangsu Chengxu Electric Group Co., Ltd. and Huati Technology in the "Kaili Economic Development Zone Street Lamp Lighting Upgrading and Reconstruction Project" are the same as or similar to the patented products of their appearance design. , So file a lawsuit to the court. The three defendants are the Urban and Rural Administration of Kaili Economic Development Zone, Jiangsu Chengxu Electric Group Co., Ltd. and Huati Technology.
Guizhou Lestar's litigation request is:
1. Order the defendant to stop infringing on the plaintiff’s design patent;
2. The three defendants were ordered to jointly compensate Guizhou Lestar for economic losses of RMB 32,420,600;
3. The defendant shall jointly bear the litigation costs in this case and the plaintiff's rights protection lawyer's fees.
In this regard, China Sports Technology does not agree with the other party’s claim that it is suspected of infringement. Huati Technology stated that the "Street Lighting Upgrading Project in Kaili Economic Development Zone" is required by the CCP to provide 2032 sets of street lamp products. These street lamp products are the company's patented products and have been approved by the State Intellectual Property Office. The patent certificate of appearance design is protected by law.
In fact, the amount of more than 40 million lawsuits is not a small sum for Huati Technology. The company's previous prospectus disclosed that from 2014 to 2016, the company achieved net profits of 35.57 million yuan, 42.56 million yuan and 48.07 million yuan attributable to the owners of the company.
So, what impact will this lawsuit have on Huati Technology? On July 25, the reporter called Huati Technology many times, but no one answered the company phone. According to Huati Technology’s announcement, the litigation "is uncertain about the impact of the company's current and subsequent profits". However, it stated that the street lamp products involved in the lawsuit are not the company's main products, and the lawsuit will not have a direct impact on the company's daily production and operation.
The other party was originally a company agent
The above-mentioned Guizhou Rexta related person stated that “Rexta” is a lighting company headquartered in Wenjiang District, Chengdu, and Guizhou Rextas involved in the litigation this time is one of its subsidiaries.
It turns out that the entanglement between Guizhou Rexta and Huati Technology has a long history. Rexta was once the regional agent of Huati Technology.
Previously, the two parties had repeatedly litigated and counterclaimed a contract dispute that began at the end of 2014.
In October 2015, Guizhou Lexida counter-sued China Sports Technology. In the relevant litigation at the time, Guizhou Lestar stated that it was once the agent of Huati Technology in Guizhou. According to the two "Lighting Products Sales Contracts" in December 2014, Huati Technology provided it with Magnolia There were 585 sets of lamps (later reduced to 583 sets), and 408 sets were actually implemented (all sold in Gui'an New District). However, some problems occurred during the execution of the contract, and the two parties later went to court on this matter.
On December 30, 2016, China Judgment Documents Network disclosed a "Second Instance Civil Judgment on the Sale and Purchase Contract Dispute between Sichuan Huati Lighting Technology Co., Ltd. and Guizhou Lexida Lighting Technology Co., Ltd.". According to the civil judgment, Huati Technology is the plaintiff and counterclaim defendant in the first trial; Guizhou Luxida is the defendant and counterclaim plaintiff in the first trial.
The ruling made by the Guiyang Intermediate People's Court only upheld the first item of the first-instance judgment: Guizhou Lexida paid Huati Science and Technology Co., Ltd. payment of 3,248,000 yuan and interest loss of 54,000 yuan, totaling 3,302 million yuan.

In addition, the "Planning" proposes to encourage enterprises to develop and promote smart lighting products suitable for various application scenarios.
Can the laser projectors defend the throne with LED screens entering the theater?
In July this year, South Korea’s Samsung Electronics announced the world’s first cinema LED display, and successfully installed this Cinema LED Screen in the Lotte Cinema World Building in South Korea. Samsung’s creative idea of applying LED displays to theaters broke the traditional concept of using projectors in theaters. So, is this idea reliable?
As for what this Cinema LED Screen launched by Samsung is, you may be a little confused. In fact, we might as well simplify this product.
Cinema LED Screen is actually the small-pitch LED splicing large screen that everyone is familiar with, and Samsung’s purpose this time is to apply the small-pitch LED large screen splicing technology to
In the theater, the most basic thing of this idea is to make the Cinema LED Screen meet the current theater configuration requirements.
LED screen enters the theater, can laser projectors defend the throne? Cinema LED Screen is actually a large screen with small-pitch LED splicing
To build a device suitable for theaters is nothing more than starting from the four elements of picture brightness, resolution, color and sound, so that the device can bring the audience a visual and auditory enjoyment. Then let's analyze the advantages and disadvantages of the small-pitch LED screen, and see if it can make Cinema LED Screen have its own place in the film projection market.
The advantages of small-pitch LED screens
Screen brightness: The screen brightness of cinema movies directly affects the user’s viewing experience. Too low brightness of the movie screen will make the viewer’s eyes tired when watching the movie.
The peak brightness of Cinema LED Screen reaches 146fl, which is 10 times higher than that of standard projectors (usually 14fl). The brighter picture of the LED screen will make it easy for the audience to watch. In addition, the LED screen also has a strong anti-interference ability against natural light and other ambient light.
LED screen enters the theater. Can laser projectors defend the throne? Cinema LED Screen has certain advantages in terms of screen brightness, resolution and color performance
Screen resolutionSurface: With the development of science and technology, it is not too difficult for display devices to achieve 4K resolution. However, due to technical reasons, the cost of 4K resolution devices is still very high and cannot be accepted by most people, plus network speed and film sources. Such restrictions have restricted the promotion and popularization of 4K resolution, but the popularization of 4K in the future will inevitably be the general trend. At present, many theaters mostly use 2K resolution projectors, and 4K resolution projectors are only used in some high-end theaters. Cinema LED Screen uses 4K resolution. Although this increases the cost of the display device, in the long run, with the resolution and equipment upgrade, the resolution of Cinema LED Screen 4K will still not be eliminated. This is also a big advantage of Cinema LED Screen.
Color performance: Cinema LED Screen uses RGB three primary color light sources (one pixel is composed of 3 LED light-emitting units). Compared with the current monochrome and two-color laser movie projectors in theaters, the color performance of LED screens in the screen It has a great advantage in capability. The only comparable projection equipment is the three-primary color laser film projector. Because the three-primary color laser light source projector uses red, green, and blue lasers as the light source, the cost is high, and there is no large-scale application. Among the theaters, only a few high-end theaters use three-primary-color laser light source projectors. This is also the advantage of this Cinema LED Screen launched by Samsung.
Disadvantages of small-pitch LED screens
The viewing distance should not be too close
Each pixel of the LED screen contains red, green, and blue LED light-emitting units. If you look at it from a close distance, you can still see the small black gaps between the screens. In addition, the large LED screen is made up of small LED units. If you look at it at close range, you can see the physical seams between the units, which will affect the viewing experience. To sum up, watching the large LED screen at close range will give people a sense of being able to see from a distance but not playful.
Large screen installation is time-consuming and laborious
Cinema LED Screen is made up of many LED LCD splicing units. Compared with laser projectors, the splicing of large LED screens takes time and effort, and the requirements for splicing technology are more stringent.
Maintenance is difficult and easy to blur the screen
The attenuation of the brightness of each LED lamp bead is different for the large LED screen, which will cause the color display of the large LED screen to be inconsistent, and the phenomenon of blurring will occur. Not only that, damage to the LED lights of any color of the LED screen will affect the overall visual effect of the display. If you change the bulb, it will be difficult to repair. Changing the LED screen unit will increase the maintenance cost of the large LED screen.
