Seeing this tunnel-like evaporation equipment that can reach hundreds of meters in length, David Fief was also stunned.

"Mr. Yang, I really didn't expect you to develop such a huge set of evaporation equipment, you must have invested a lot of research and development funds, right?"

Yang Jie smiled: "The research and development of such a set of equipment is indeed very expensive. ”

In order to develop such a set of special evaporation equipment, Tianma Technology Company has spent nearly one billion R&D funds.

Because Tianma Technology Company uses small molecule luminescent materials, including cathodes, a total of 5 to 6 layers of organic thin films and electrodes need to be evaporated by evaporation process, and there are more than a dozen vacuum evaporation chambers in such a set of equipment.

"Mr. Yang, such equipment is too expensive, using such expensive equipment to prepare the screen, coupled with the low utilization rate of organic materials in the evaporation process, the speed is also slow, and the production capacity is very low, such a high production cost, the price of the displayed screen produced must be very expensive, and it is still very difficult to enter the consumer market, right?"

Yang Jie glanced at David Fife and said with a smile: "Although the production cost of this process we have mastered is very expensive, it can now be close to mass production, as long as mass production is achieved, the production cost can still be reduced quickly." ”

"Mr. David Fief, your company is developing the bracketing technology for inkjet printing of polymer luminescent materials, but this technology is not yet up to the requirements for mass production, right?"

“......”

David Fief was speechless at this time, the inkjet printing process is not yet mature, coupled with the limitations of material types and properties, there is still a long way to go before mass production.

"At this stage, polymer luminescent materials can adjust their luminescence wavelength through chemical modification, and have now obtained a variety of colors covering the entire visible range from blue to green to red, but the life of this material is only one-tenth of that of small molecule luminescent materials, and the luminous efficiency is lower than that of small molecules. ”

Yang Jie opened his mouth and said.

David Feife's face also flashed a gloom, "Mr. Yang, are you not optimistic about polymer organic laser display technology?"

"That's not, Tianma technology company's current energy is mainly focused on small molecule organic laser display technology, if your company and our company together to develop polymer organic laser display technology, in the material and process mature, the company will launch this complete set of technology to domestic and foreign manufacturers. ”

Yang Jie said: "We can't be sure of this time node, and we can only promote it according to the progress of polymer organic laser display technology." ”

David Fief nodded, although Cambridge Display Technology Company has a lot of technical patents for polymer organic laser display technology, but now it can only be a small size panel, the largest size is only the size of A4 paper, not full color, only suitable for cutting into some small digital products used on the screen, because the output is small, it is not much money.

Cambridge Display Technology's revenue was less than $20 million last year, mainly based on technology research and development, mainly providing display drive technology, polymer materials, and small-size polymer organic laser display product technology.

Because this company is a company separated from Cambridge University, and has been conducting research and development in the field of polymer organic laser display, it has a large number of technical patents on hand, but John Bull has no domestic industrial support, so there is no way to develop in a short period of time like Tianma Technology Company.

This company is very technically strong, but it can only exist in the form of a small business, and it is in a state of starvation.

This time, David Fife saw that Tianma Technology Company had such a large and sophisticated high-end equipment in just one laboratory production line, and his heart was drooling - Tianma Technology Company is so rich!

Before he came, David Fief knew that Tianma Technology Company, a subsidiary of Huaxing Group, was the most profitable LCD screen high-tech company in the world, and now he was even more sure of this opinion after seeing this experimental production line.

This experimental production line is a complete production line, in addition to evaporation, dispensing, packaging, aging, cutting, testing and other aspects of the equipment are brand new, and the use of laser annealing and laser stripping and other advanced equipment.

David Fief learned that most of the equipment was designed and developed by Huaxing Group itself, and his heart was also shocked.

Huaxing Group can design and produce such high-end equipment, and master the complete technology of small molecule organic laser display, how can other companies compete!

Thanks to Tianma Technology, there is no idea of competing for market share with other LCD panel manufacturers, otherwise how can other LCD panel manufacturers live?

In the product technology exhibition area,Tianma Technology Company also displayed several different sizes of organic laser display TVs,These TVs are very thin and light,The thinnest place is only three millimeters,The picture displayed on the screen is extremely clear,Delicate,Saturated and gorgeous colors,And the high-speed motion picture is also no picture drag blurred place。

On the one hand, the technician said proudly: "The active organic laser display driver technology developed by our company realizes the arrangement of more transistors and capacitors in each pixel unit, so that the brightness of the pixel unit is more uniform, and also realizes the compensation circuit for the pixel unit, which can make the image quality reach a very high level and the response speed is faster." ”

David Fief is not easy to fool, after all, he himself is an expert who has been engaged in polymer organic laser display technology for a long time, and then asked: "I know the advantages of organic laser display screens, but this kind of screen is also defective, the most obvious is that the low brightness of the interference to the color rendering, uneven color, color rendering is not accurate, how do you solve the problem?"

The pixel unit on the organic laser display screen itself is luminous, the screen has no backlight plate, each pixel emits light independently, and it will appear in the case of low brightness, and the problems such as screen color cast, uneven luminescence, gray scale deviation and deterioration are very obvious.

Apparently Cambridge Display Technologies is experiencing a similar problem.

The senior engineer glanced at Yang Jie and Jiang Biwang, the president and chief scientist of Tianma Technology Company next to him.

Yang Jie said to Guo Chaohua beside him at this time: "Chief Engineer Guo, you can talk about it." ”

Guo Chaohua is the chief engineer of Tianma Technology Co., Ltd., focusing on display engineering technology, previously served as the main technical leader in the display business unit of Kodak Company, has been engaged in LCD screen and organic laser display technology, he resigned from Kodak five years ago and entered Tianma Technology Co., Ltd. as the chief engineer.
