TFT-LCD modules in 4 to 5.5in now lead shipments as smartphones migrate to larger displays.
Mainland China companies continue to offer 3 to 6in TFT-LCD modules in resolutions of 480x854, 720x1280 and 1080x1920 pixels, brightness levels of 400 to 800cd/sqm and contrast ratios of 600:1, 800:1 and 1,000:1. All products use LED backlighting.
Owing to the popularity of larger screens, especially in smartphones, releases in 4 to 5.5in now dominate shipments.
Most manufacturers source key components such as TFT-LCD panels, touchscreens, LED backlights and PCBs from domestic and Taiwan providers.
The cost of the panels rose in 2016 due to the short supply of glass substrates, which come mainly from Corning, Asahi Glass and Nippon Electric Glass or NEG, resulting in an increase of module prices exceeding 20 percent.
This year, local suppliers expect the panel cost and supply situation to improve and stabilize module rates as mainland makers of glass substrates such as Irico and Dongxu boost production. The latter company, together with its subsidiary Fuzhou Tunghsu, entered into an agreement with NEG to establish a joint venture for this in 2016.
Here is a selection of 3 to 6in TFT-LCD modules from mainland China.
