Sychip PDA dedicated full integration of the 3.5 inch LTPS panel appearance

Sychip days ago announced the successful development of a fully integrated all drive circuit (including vertical and horizontal scanning circuit, the DC voltage conversion circuit, digital analog conversion circuit, a timing controller and interface circuit) 3.5 inch LCD module in low-temperature polysilicon on the panel (Full-IC-integrated SOP LTPS TFT-LCD module). It is worth mentioning that the 3.5 inch LTPS display module of the TPO was the first in the world can be applied to PDA full integrated SOP TFT-LCD (Full-IC-integrated).

The 3.5 inch (Full-IC-integrated) and the integrated design of SOP LTPS TFT-LCD module designed for high quality PDA image display, a resolution of 240 * RGB * 320, 262K has a full-color image display quality, and is expected in the first quarter of 2006.

When the driving circuit is fully integrated in the panel (SOP), not only the display panel will no longer need any external IC, and because the IC function has been integrated in the panel, the panel designers can be master of their own design and development and characteristics of IC, can reduce the time of product development and the characteristics of optimal products.

But compared to the CMOS semiconductor production driver IC on the wafer, in low-temperature polysilicon (LTPS) process to fully integrated circuit on a glass substrate is a major and difficult project, the investment research institutions and the development of SOP company encountered the biggest technical bottleneck is that even if the circuit can integrated on the glass substrate, can maintain the original panel size and total power consumption. However, TPO with its advanced circuit design, FASt (Fully Self-Aligned Symmetric) collocation of TFT process and component technology, using LTPS to process the external circuit of the existing IC in the integrated directly on a glass substrate. Especially in the aspect of circuit design, the advanced high performance circuit Tongbao development, not only provides stability and high product durability, is also effective in reducing the overall power consumption of the panel, in full color screen display panel, the total power consumption is less than 30mW; while the panel size is maintained and the external current amount of products.
