In the past few years, the most advanced LCD panel manufacturing technology has rapidly shifted from large-scale television applications to high-resolution mobile applications. As the screen resolution of high-end mobile applications has exceeded 400ppi and continues to move towards higher resolution, the production of LCD panels for mobile applications is actually more challenging in many aspects than the manufacture of large-size LCD panels. In addition, minimizing display screen energy consumption for most mobile products is key to increasing the relatively short standby time of mobile applications.

According to the latest research report from NPD DisplaySearch, the development goals of top LCD manufacturing technologies in 2013 and 2014 were mainly to improve resolution, reduce energy consumption, improve picture quality (such as color saturation and contrast), ergonomics, and reduce costs.

Advanced technologies such as low-temperature polysilicon (LTPS), metal oxide TFT, dye-type CF, and RGBW can improve pixel aperture ratio, increase transmission speed and brightness, and at the same time reduce backlight illumination. To achieve the purpose of reducing energy consumption.

Narrow bezel reduction is an important trend in ergonomic handheld devices, especially as smartphone screens continue to grow and 7'' screens are popular in the tablet market. LTPS and oxide TFT are the main technologies to reduce the width of the bezel. Their high electron mobility can reduce the circuit size of the GOA (gate array) and reduce the outer border.

Advanced LC Modes and Optical Alignment, especially recent advances in negative IPS/FFS liquid crystal and IPS/FFS optical alignments, are important for enhanced transmission speeds and improved color contrast. development trend. These technologies can be combined with each other and have the opportunity to be used in the upcoming iPhone 6.

Quantum Dot-based backlights can simultaneously improve luminous efficiency and color saturation. Compared to the traditional way of improving the color saturation, such as using more color resists that affect the transmission speed, this method is more advanced. In this way, 100% NTSC color reproduction is possible with less cost. Because this kind of technology can greatly improve the picture quality, brand manufacturers are concerned about their technological development trends. It is well known that OLED has a great advantage in the color of the picture, and a quantum dot-based backlight can provide a color display equivalent to AMOLED to the LCD panel.

In the search for high-quality graphics and low-cost LCDs, the trade-off between specification and manufacturing technology is an eternal theme.

Many new technologies can provide better performance, but manufacturing yields are low, and low yields also mean higher costs.

In other words, these manufacturing technologies still require the successful use of many specialized experiences and proprietary technologies. A panel manufacturer can use these new manufacturing technologies and it does not mean that other vendors have the ability to use them. Therefore, manufacturers use such methods to have competitive advantages that other manufacturers do not have.

Because any kind of production technology that can both reduce costs and improve performance can provide panel manufacturers with two competitive advantages at the same time, it is bound to become the primary research object.

Flat panel display products are everywhere nowadays. With the use of low-cost, high-quality, application, and comfort-enhancing technologies discussed in the NPD DisplaySearch report, there will be more and more flat-panel displays in our lives in the future.
