    Abstract: A display device includes a frame, a protrusion, a display panel, a protective substrate, and a buffer material. The frame includes a bottom plate and a side plate; and the bottom plate has an inner surface, and the side plate is on the inner surface of the bottom plate. The protrusion is disposed on the inner surface of the bottom plate. The display panel is disposed on the protrusion and includes a force sensitive layer. A protection substrate is disposed on the display panel. The buffer material is connected with the protection substrate and the side plate of the frame, and the buffer material has a greater elastic coefficient than the protrusion.

    Abstract: A touch display device includes a controller, a source driver, several multiplexers, and several touch sensors. The source driver is configured to output several data signals. The multiplexers are coupled to the controller and the source driver, and are configured to transmit the plurality of data signals to an active area according to at least one enable period of a multiplexing signal. The touch sensors are coupled to the controller, and are configured to receive a touch signal outputted from the controller. The touch signal includes a touch pulse. A touch pulse starting-time interval and a touch pulse ending-time interval of the touch pulse are located in at least one disable period of the multiplexing signal, and the touch pulse and the at least one enable period partially overlap in time sequence.

    Abstract: A touch display apparatus including a first substrate, a first sub-pixel, a spacer, a second substrate, and a touch-sensing electrode is provided. The first sub-pixel is disposed on the first substrate. The spacer is disposed on the first substrate. The touch-sensing electrode is disposed on the second substrate and has a first opening. The spacer is located inside the first opening in an orthogonal projection direction. A distance D is defined between an outline of an orthogonal projection of the spacer on the first substrate and an outline of an orthogonal projection of the first opening on the first substrate, and D≥5 μm.
