Display panel

A computer-implemented method (100) performed by at least one processor (16, 20) at a touchscreen display system (1), the method comprising:

• generating (110) a visual representation (5) at a graphical display (3) based on visual display output signals (13) received from via a first communication interface (11);
• determining (120) based on touch data input signals (12) from a touch panel sensor (7), one or more locations of a touch input (9) from a user (10) relative to the graphical display (3);
• generating (130) pointing device input signals (19) based on the one or more locations of the touch input (9);
• and
• sending (135) the pointing device input signals (19) to the host device via the second communication interface (17),
• wherein the first communication interface (11) is separate to the second communication interface (17).

A computer-implemented method (200) performed by at least one processor (61) at a host device (15), the method (200) comprising:

• sending (201), to a touchscreen display system (1) via a first communication interface, visual display output signals (13) for generating a visual representation (5) at a graphical display (3);
• sending (203), to an alternate graphical display (34), alternate visual display output signals (36) for generating an alternate visual representation (38) at the alternate graphical display (34);
• receiving (204), from an alternative pointing device (31) of the host device (15), an alternative pointing device input signal (19), wherein the alternative pointing device input signal (19) includes at least a preceding cursor location (33) associated with the visual representation (5), or alternative visual representation (38);
• receiving (235), from a touchscreen display system (1) via a second communication interface, a pointing device input signal (19), wherein the pointing device input signal (19) comprises:
• in a first mode, an active screen control notification (27) and at least a cursor location (21),
• wherein the active screen control notification (27) is indicative of an active touch input (9) of the user at a touch panel sensor (7) of the touchscreen display system (1), and
• wherein in response to the active screen control notification (27), the method includes switching (236) the cursor location (21) to a corresponding location (18) at the generated visual representation (5) displayed on the graphical display (3).
