    Abstract: A haptic reproduction system comprises: a touch display device, an upper computer and a waveform generator. The touch display device comprises a piezoelectric unit, a touch display panel and a touch driving unit. The piezoelectric unit is disposed on the touch display panel. The touch driving unit is electrically connected to the touch display panel and the upper computer, and is configured to acquire touch information and transmit the touch information to the upper computer. The upper computer is electrically connected to the waveform generator, and is configured to send a first waveform generation instruction to the waveform generator according to the touch information. The waveform generator is configured to generate a first waveform signal according to the first waveform generation instruction. The piezoelectric unit is electrically connected to the waveform generator, and is configured to resonate with the touch display panel under the drive of the first waveform signal.

    Abstract: Provided is a display panel, including: a substrate, a plurality of sub-pixels, a plurality of data lines, and a black matrix; wherein each the sub-pixel is divided into at least two domains along a column direction of the array; and the data line deviates from the column direction of the array and bends toward the row direction of the array to form a corner, wherein a distance between an outer edge of an orthographic projection of the black matrix covering the corner onto the substrate and an outer edge of an orthographic projection of the corner onto the substrate is greater than a distance between an edge of an orthographic projection of the black matrix covering rest of the data line onto the substrate and a corresponding edge of an orthographic projection of the data line covered by the black matrix onto the substrate.
