Head-up haptic display device for vehicle

A head-up haptic display device for a vehicle comprising:

• a display unit configured to display information on a display area and to sense a touch input and a pressing input of a user with respect to the display area;
• a haptic unit configured to provide the display area with vibration, and a resistance force with respect to the pressing input;
• and
• a control unit configured to control the haptic unit,
• wherein the display area comprises a button area and a non-button area,
• wherein the haptic unit is further configured to:
• provide a first resistance force when the pressing input is applied to the button area;
• and
• provide a second resistance force, which is greater than the first resistance force, when the pressing input is applied to the non-button area,
• wherein the display unit is configured to exhibit different displacement states relative to the haptic unit, depending on whether the first resistance force or the second resistance force is provided, and
• wherein the different displacement states are generated by a mechanical interaction between the display unit and the haptic unit caused by different magnitudes of the first resistance force and the second resistance force.
