Abstract: A touch display device is provided which includes a display panel for displaying an image, and a touch screen panel disposed on the display panel and configured to sense at least one touch. The touch screen panel includes a touch substrate at which the touch can be generated; sensing electrodes provided on the touch substrate and spaced apart from one another, each of the sensing electrodes being formed of a piezoresistive material having a resistance value that varies according to an applied force; and a touch processor electrically connected to the sensing electrodes. The touch processor extracts a touch coordinate based on time constants of sensing signals applied to the sensing electrodes, and calculates a touch force of the touch based on resistance values of the sensing electrodes.

Abstract: A display apparatus including a display panel, a polarizing member having an absorption axis and a transmission axis, and a first touch electrode extending in a first direction is disclosed. The first touch electrode includes first touch patterns and a connection pattern connecting adjacent first touch patterns in the first direction. The connection pattern has a minimum width in a direction perpendicular to a second direction. The first direction and the absorption axis direction form a first directional angle equal to or less than about 90 degrees. The first and second directions form a second directional angle equal to or less than about 90 degrees. The second and absorption axis directions form a third directional angle equal to or less than about 90 degrees. The first directional angle is the sum of the second directional angle and the third directional angle.
