Abstract:
Displays such as liquid crystal displays may be used in electronic devices. During operation of a display, electrostatic charges on the surface of the display may give rise to electric fields. One or more electric field shielding layers may be provided in the display to prevent the electric fields from disrupting operation of the liquid crystals material in the display. The shielding layers may be formed at a location in the stack of layers that make up the display that is above the liquid crystal material of the display. Touch sensors and thin film transistors may be located below the shielding layer.
