Sharp to Commercialize World’s First Small- and Medium-Size LCD Panels using Oxide Semiconductor

Sharp Corporation has developed high performance small- and medium-size LCD panels using oxide semiconductor, InGaZnO (IGZO*1). Production of these new LCD panels will aim to start at Kameyama Plant No.2 within this year.

Meeting the strong demand for small- and medium-size LCD panels used in smart phones and tablet terminals, is accompanied by an increased need for display quality, including high resolution and high picture quality, light weight and compact design, and high energy efficiency.

In collaboration with Semiconductor Energy Laboratory Co., Ltd.*2, Sharp has developed and will commercialize a thin-film transistor using a new material, InGaZnO, a world’s first. High energy performance LCD panels will be made possible by downsizing the transistor and by increasing the light transmittance for each pixel. In addition, Sharp’s unique UV2A*3 technology will achieve high display quality small- and medium- size LCD panels. The cost-competitive high efficiency production line will use 8th-generation glass substrates, and will utilize the current Kameyama Plant No.2 production line, with manufacturing to start within this year.

Kameyama Plant No.2 has started operation from August 2006, and has been producing cutting-edge LCD panels for TVs. From now on, this plant will additionally produce cutting-edge small- and medium-size LCD panels. Sharp will continue to further strive to make an advancement of state-of-the-art LCD panel plant using its unique production technology.
