LP6288QVF: 4K/8K FHD panel power management chip

In the past two years, the development of 4K has been like a miracle, and it can be said to be a sudden and rapid development. In the Internet era, display products are at the forefront of human-computer interaction experience. High-definition resolution brings the most intuitive experience to users. With the upgrading of display technology and consumption, people's demand for resolution is also getting higher and higher.

In addition, the global market demand for TFT-type liquid crystal materials is strong. TFT-type liquid crystal materials account for more than 80% of the total output value in the global liquid crystal material market. With the rapid development of LCD TVs, laptops, desktop monitors, and mobile communications, the demand for TFT-type liquid crystal panels continues to increase. In 2016, the global demand for TFT-LCD panels was 171 million square meters. It is estimated that the global TFT-LCD panel shipment area will reach 185 million square meters in 2019. According to 80% of the effective display area, 4.5g of liquid crystal material per square meter of panel, and the average price of mixed liquid crystal materials of about 15,000 yuan/kg, the global demand for TFT mixed liquid crystal in 2016 was about 617 tons, and the market size was about 9.3 billion yuan. It is estimated that the global demand for TFT mixed liquid crystal in 2019 will be about 666 tons, and the market size will be about 10 billion yuan.

Dai Xingke, General Manager of Micro-Source Semiconductor Co., Ltd.

Dai Xingke, general manager of Micro-Source Semiconductor Co., Ltd., introduced that LP6288QVF is China's first PMIC for high-definition display screens independently developed and mass-produced by China. This product is a highly integrated digital-analog hybrid design, which makes the display color more vivid through I2C programmable control. The built-in 10-channel power management and power conversion are high-voltage boost, 3-channel buck conversion, charge pump boost, negative voltage boost, Vcom control, reset, I2C programmable control, memory, DAC conversion, and system power management.

The main products of domestic liquid crystal material enterprises are liquid crystal intermediates, liquid crystal monomers, and low-end mixed liquid crystals. The market share of TFT mixed liquid crystals is extremely low. In recent years, due to the support of national industrial policies, the construction of multiple domestic high-generation panel production lines, and the increasing cooperation and exchanges with foreign companies in the same industry, domestic liquid crystal material companies have developed greatly and have mastered certain core technologies, production capacity, and output bases. At present, there are more than 10 domestic companies producing liquid crystal materials, but most of them are mainly producing intermediates and monomers. There are very few companies with mixed crystal production capabilities, and they are mainly low-end liquid crystal materials of TN, HTN, and STN series. The market share in TFT mixed liquid crystals is still relatively low. At present, domestic liquid crystal material companies are stepping up their efforts to develop TFT mixed liquid crystals, and the development prospects are broad. Domestic companies will have more and more localized competitive advantages. The technology of domestic upstream material companies is rapidly improving. While meeting the low-end and mid-end markets, they are gradually advancing to the high-end market. With the continuous expansion of geographical advantages, cost advantages, and synergy advantages, it is an inevitable trend for local companies to strengthen cooperation. Therefore, local companies will have more and more competitive advantages under comprehensive considerations of cost, technology, and cooperation.

Thanks to the decline in screen prices, the price of a 60-inch standard TV may fall below RMB 1,000 within three years, and the size of TVs consumed will continue to grow. Weiyuan is the only manufacturer in mainland China that can ship analog chips for panels. The breakthrough of analog chips requires a long period of experience accumulation, and the cycle for mass production of analog-based digital hybrid chips requires more than 3-5 years.
