CG-Silicon Displays with Integrated Drivers
Sharp Laboratories of Europe is collaborating with Sharp's Liquid Crystal Development Group in the design and advancement of integrated driver electronics for mobile LCD modules. Displays of this type have the highest resolution in their class, and find application in high quality mobile phones, digital cameras and personal information tools.
Using Sharp’s advanced Continuous Grain Silicon (CG-Silicon) thin film transistor process, it is possible to form display driver circuits on the glass of the display. This leads to slim, light and robust high-resolution displays. The System Display Group is actively researching techniques for the integration of the entire display module onto the glass. Recent developments include low-power digital-to-analogue converters and timing generators (see our recent paper at SID '04).
The display pictured includes these developments, and is designed to operate under the low power requirements of a typical mobile device. Below is a picture of the layout of the corner of the display, showing timing circuits, a D-to-A converter, and part of the pixel matrix.
