LG Display, the world's second-largest manufacturer of liquid crystal displays (LCDs), is planning a series of display innovations to renew its focus on mobile devices, according to the company's management.
The company has invested more than 577.1 billion won (about $463 million) to establish manufacturing facilities for low-temperature poly silicon (LTPS) LCDs, and will also add muscle in organic light emitting diodes (OLEDs) to exploit rising demand in mobile phones and portable media players.
LG Display held a ceremony for equipment installation at its planned LTPS plant at its Paju LCD cluster in Gyeonggi Province, Wednesday.
The LTPS line is expected to begin production in the first quarter of next year, with a monthly capacity of 20,000 panels per month.
``We are finding a growing demand for small display panels that are generated from high-end consumer electronics devices and smart phones,'' an LG Display executive said.
``We are seeing an increasing demand for LTPS displays in high-end portable devices.''
LTPS LCD screens promise higher resolution and better picture quality than displays made with amorphous silicon substrates, company officials said. The production of LTPS screens is based on laser-driven crystallization technology, and the larger and more uniform grains of poly silicon in the displays flow 100 times faster than the random-sized grains of amorphous silicon in other displays, which result in higher resolutions and speed.
LTPS LCDs are also better equipped to produce smaller and thinner displays, LG Display officials said, because pixel thin film transistors (TFTs) and driving circuits could be integrated together onto the glass substrate, which reduces the TFT section and the wiring between the pixels.
Devices using LTPS displays also consume less power than those using amorphous silicon TFT LCDs.
LG Display also spent 90 billion won to establish an OLED line, which will produce 8,000 panels per month by the end of next year, to meet the industry's growing demand for active matrix OLED (AMOLED) displays driven by mobile phones.
