Abstract:
1. A liquid crystal display (LCD) apparatus, comprising: a first substrate; a plurality of display electrodes formed on the first substrate for receiving a display data; a second substrate; at least one sensing photo spacer protruding on a first surface of the second substrate; and a conducting layer covering on at least a part of the first surface and the at least one sensing photo spacer; wherein when combining the second substrate with the first substrate, the at least one sensing photo spacer is opposite to one of the display electrodes arranged at a corresponding location, and the conducting layer covered by the at least one sensing photo spacer is not electrically coupled to the display electrodes, and when pressing a second surface of the second substrate opposite to the first surface thereof, the conducting layer covered by the at least one sensing photo spacer adjacent to the pressed location contacts with the corresponding display electrodes, and a perpendicular projection of the at least one sensing photo spacer protruding covers a portion of corresponding display electrode, and a shield metal be formed under the sensing photo spacer protruding.
