Toshiba Mobile Display develops a 7.0-inch low-temperature poly-silicon thin-film transistor liquid crystal display
Toshiba Mobile Display has developed a 7.0-inch low-temperature poly-silicon (LTPS) thin-film transistor (TFT) liquid crystal display (LCD) for vehicle-mounted and industrial uses that enables multi-touch input on the display screen without the need for additional installation of a touch panel. The technology enables an integrated touch panel function by forming the display pixel electrodes and TFT within the LCD panel using LTPS TFT technology and creating a detecting circuit for electrostatic capacitance changes between the electrodes and the peripheral object. Compared to conventional LCDs with an external touch panel, the thickness is reduced by 57 percent to approximately 1 millimeter, the weight is reduced by 48 percent to 225 grams and the surface reflection ratio is reduced by 10 percent. Its smaller size enables the design of more compact products for mobile applications, reduces the impact on the environment by saving resources and power, provides crisp and clear images with minimal reflection of natural light even in a bright environment, and features intuitive multi-touch input.
Toshiba Mobile Display has developed this technology in response to the increasing demand for in-cell touch panel LCDs with the touch panel function integrated in the LCD panel for further reduction of thickness, weight and environmental impact. This technology will be exhibited in the Toshiba booth #1119 at SID 2011 International Symposium, Seminar and Exhibition to be held from May 17 to May 19, 2011 in Los Angeles, Calif., USA.
