Beschreibung
Zusammenfassung:	A touch display panel with switchable viewing angles includes a first substrate, a second substrate, and a liquid crystal layer between the first substrate and the second substrate. The first substrate is provided with a viewing angle control electrode. The second substrate is provided with a common electrode and a sensing circuit layer. The common electrode includes a plurality of electrode blocks arranged in an array and insulated from each other. The sensing circuit layer includes a plurality of sensing lines insulated from each other. The sensing lines are electrically connected to the electrode blocks in a one-to-one correspondence, respectively. Each frame of the display panel is divided into a display period and a touch period. The electrode blocks of the common electrode are used for image display during the display period, and the electrode blocks of the common electrode are used for touch sensing during the touch period.
