Touch-sensitive display for climate control with fan,
air-conditioning, clock, and ventilation controls. Each
touch-sensitive icon is implemented as an outline icon
and a solid icon. Outline icons indicate where to touch;
solid icons display after the outline icon is touched.
Sample displays
On-cell ITO touch layer
Polarizer
ITO touch layer
Glass
ITO layer
(electrode)
Liquid crystal
Compared to the normal structure,
where the ITO touch glass is
implemented outside the LCD
structure, the on-cell technology
offers the following advantages:
- S impler structure: two glass layers
instead of three
- Thinner thickness
- Easier assembly
- Lower cost
