"Mr. Fief, we have used at least three different technical solutions for this defect you mentioned, but the results are not satisfactory, and now we are developing according to the technical route proposed by Mr. Yang to add the layer mixer function and ambient light sensor to the image processor, and now we have made some progress. ”

Guo Chaohua said.

David Fief was stunned for a moment, and then said: "We have also carried out research and development on dimming technology before, and I didn't expect you to find a way to find a way from the internal functions of the image processor. ”

Yang Jie smiled: "I don't know what kind of dimming technology your company uses?"

"Our company wants to start from the software and use the software to mask the brightness of the image, but this technical solution does not work very well, and there are still problems of screen color cast and uneven luminescence. ”

Everyone is an expert in technology, in fact, the solution is similar to everyone, mainly depends on which solution everyone concentrates on.

Compared with dimming on the software, just adjusting the overall brightness on the screen will definitely cause problems such as flickering screen color accuracy, dynamic range, contrast, and color levels.

However, the way chosen by Tianma Technology Company is to use the processor to adjust the color accuracy, dynamic range, contrast, color level, etc. of the display screen under low brightness, which is very difficult, and the image processor is required to process each frame of the picture, and the amount of calculation is very large.

Fortunately, Tianma Technology Company is behind the huge high-tech company Huaxing Group Company,If it is a TV manufacturer encountering such a problem,The most time-saving and energy-saving way is to use software to reduce the brightness of the picture as a whole,Naturally, the screen flickering cannot be avoided。

David Fief had to sigh in his heart that Tianma Technology's technical strength and determination and attitude to solve the problem in this regard really wanted to solve the problem from the root, not a small repair, and really wanted to develop a good product.

After this contact, Tianma Technology's investment in the research and development of technical products and the rigorous, meticulous and creative atmosphere also made David Fife feel very deeply.

Later, he also asked about the "screen burn-in" that will occur in organic laser display technology.

The so-called screen burning, in fact, is the situation that the aging of different parts of the organic laser display screen is not synchronized, resulting in local defects on the display.

Because each pixel of the organic laser display screen can be self-luminous, and the luminous time of different pixels is different, the attenuation speed of each pixel will be different, which leads to the "screen burning" problem mentioned by David Fief.

Although theoretically speaking, in most cases, users usually browse different content when using mobile phones, on average, the aging of all pixels is basically the same, but users stay in the same picture for too long, it will cause different parts of the organic laser display display to age differently,

In the previous life, even the top organic laser display "burn-in" could not be completely avoided, and such a problem occurred not long after the top flagship machines launched by Apple and Samsung.

A large part of the reason for this problem is the life of these luminescent materials, especially the life of materials that emit different colors, and if the material is not pure enough or defective luminescent materials, the life will be even shorter.

In the research and development of luminescent materials in the Kodak company is in the forefront, Guo Chaohua from Kodak company, he also led the technical team to conduct a lot of research on luminescent materials after entering Tianma Technology Company, and also acquired a small molecule luminescent material supplier from Germany Nova Yide, this company has mastered the special process of organic dopants and devices, Tianma Technology Company has acquired the company at a purchase price of more than 200 million US dollars.

It is also after the acquisition of this company that Tianma Technology has greatly improved the performance and life of small molecule blue light light-emitting materials, and at the same time, the luminous efficiency of light-emitting devices processed by the preparation process of Nova Yide has reached a very high level, and the service life has reached or even exceeded many application requirements.

Tianma Technology Co., Ltd. has established a complete set of technical patents from the R&D, design, production and manufacturing process and equipment of materials, devices, organic laser display panels, and drive processor software and hardware in small molecule organic laser display technology, which is very complete.

At this stage, in addition to Tianma Technology Company, there is only Neon Country left, but at this stage, the rabbit occupies an absolute advantage in the scale of the LCD panel industry, as long as the technology is promoted, the rabbit domestic will be able to achieve large-scale production in a short period of time, and the situation of Neon Country and South Korea in the organic laser display industry will not change much.

The founder of this Huaxing group company is too high in technology and business, the vision is very accurate, and he is willing to invest a lot of manpower and financial resources in the right things, and he is very bold.

David Fief was shocked to discover that Tianma Technology Company had reached such a level in small molecule organic laser display technology.

Also shocked were the members of the delegation from John Bull, who were also shocked by the strong strength of Tianma Technology in display technology.

Yang Jie also held talks with the members of the delegation the next day, and also mentioned the request for cooperation with these enterprises.

Although John Bull is a weak player in the display industry, some companies have a very deep foundation in material preparation and process, and can provide cadmium-free quantum dots, resins and thin films, as well as many semiconductor materials.

Huaxing Group has been these companies before the product technology of the enterprise to find out clearly, what technology is needed by Huaxing Group Company, what is not needed, the content of cooperation is very clear.

Yang Jie then also had a separate meeting with David Fief of Cambridge Display Technologies.

"Mr. Fief, I am interested in buying your company wholly in the company, what do you have to say?"

"Mr. Yang, our company has a lot of shareholders ......"

"There is no problem with this, we will obtain the approval of the shareholders' meeting and pay compensation to the shareholders at the same time, and if an agreement is reached, Cambridge Display Technologies will be merged into Tianma Technology in the future. ”

Yang Jie looked at David Fief and said: "As for whether Cambridge Display Technology will operate independently as a wholly-owned subsidiary after the acquisition, I will also ask Tianma Technology to increase investment in research and development of polymer luminescent materials and ink printing technology." ”
