LED chip manufacturing on the road under the new situation

LED chip LED lamp is often called the "heart", its quality directly around the LED lamp LED display quality and. Small pitch LED nowadays hot, for the domestic LED chip manufacturing enterprises to bring opportunities, but also challenges. In the LED chip special, the author invited Hangzhou Silan azure Co. Ltd., Au Optronics Co, Au Optronics Co, Huacan three crystal ingot morning photoelectric (Shenzhen) Co. Ltd., Xiamen dry according to Au Optronics Co and other companies related to a LED chip manufacturer in the new situation of the "core design of core manufacturing" road.

1 currently in the field of LED display, small spacing is becoming the mainstream of the development of the industry, and this trend is more obvious. Do you think the rapid development of small spacing will bring opportunities and challenges to domestic chip manufacturers?

General manager Jiang Zhongyong Silan azure:

This year's small spacing is indeed growing, but it is generally believed that the growth rate is a bit slow. With the use of small space in the field of display, the number will increase, and this fact is bound to put forward higher requirements on product quality. Relative to the enterprise, how to crack the technical problems, improve product performance and quality is the key to survival, development and growth. Many enterprises to seize the opportunity of the development of small spacing, the difficulties and difficulties, key problems in product will solve the small space, so as to produce high quality products recognized by the market, the enterprise will obtain better survival and development opportunities, on the other hand, may make the enterprises fall into a passive situation. At present, the quality of the packaging and the quality of the chip has not reached a very ideal state. Therefore, continuously improve the quality and stability of the two aspects of the packaging and chips, as a small distance enterprises in terms of a long way to go.

Shi Songgang, director of marketing:

Small pitch LED display technology with its seamless and excellent display effect, the next few years will show explosive growth. Small spacing display because of its dense spacing more demand for chips will increase, and now the market capacity is rising, visible is not a small room for growth in the future, this is a good opportunity for chip companies. But the small spacing display on the chip has a higher technical requirements, such as: how to achieve LED display small current and small capacitance consistency? How to better meet the low brightness and high ash high quality? This requires the chip companies continue to enhance the epitaxial and chip technology to meet the needs of the market, and only the technology of the enterprise, in order to stand out in the market competition.

An optoelectronic product planning manager Guo Yuntao:

The development of the small screen, which means that the chip packaging volume will be smaller, the layout will be more dense. For the size of the chip, the requirements of miniaturization and other optoelectronic properties will become more stringent requirements.

Crystal silver morning deputy general manager Wang Junbo:

For now, the domestic LED display has been in the field of rapid integration and, in particular, the small spacing of this chip application market, the integration speed faster than other applications market. On chip companies, including crystal electric may be three to four, the main house, I think this pattern should not have too big change, because the market continuously through the whole development and has become mature, large, want to enter this field is not so easy. Small spacing display chip using the number of teeth will be more, for the application and development of crystal electric small spacing display screen are.

Zhang Yong, chief engineer:

One of the characteristics of small spacing display is high-density. High density will increase the use of LED chips, which means that the increase in market demand, no doubt to the LED chip manufacturers have brought new opportunities. Of course, with the decrease of the distance between the chips, but also put forward higher requirements on the chip: consistency and reliability to make LED chip has better, but also to meet the low light high ash, high refresh rate, high scanning application requirements, which gives the LED chip manufacturing enterprises has brought new challenges.

2 small pitch products are highly integrated, including the unit area beads are more and more, your company is how to improve the design, improve the photoelectric conversion efficiency of the chip?

For small spacing display products, it is more and more because of beads contained, so it is of single lamp brightness is more and more low, the photoelectric conversion efficiency of the chip is no longer the focus of attention.

This year, China can take the lead in the industry launched a small space dedicated X series chips. This series of chip design: a new direction for the optimization of epitaxy and chip technology, realized in the wide viewing angle, high refresh, show the effect of low light high ash quality in pursuit of better, wide viewing angle, light uniformity, small photoelectric current consistency, consistency and open a small capacitor industry's high reliability standards set X series of chips in the industry benchmark for quality, reduce the death rate of light, to ensure the stability of the screen body.

For the display, the requirements on the chip is mainly to improve the whole screen in the high brush may cause damage to the chip, it will focus on the reliability of the chip characteristics.

We have always been the misconception that LED products must be brighter the better. In fact, the focus of small spacing products are not necessarily how the brightness. Because in many cases, the need for a low degree of darkness to show results. In the end, the problem is not in the photoelectric conversion
