Abstract: A touch display panel and a touch display device are provided, relate to the field of display technology. In an embodiment, the touch display panel includes a plurality of first touch electrode units and a plurality of second touch electrode units. In an embodiment, each of the first touch electrode units includes first touch electrodes and first connection portions alternately arranged in a first direction. In an embodiment, each of the first touch electrodes includes at least one first touch electrode sub-unit that includes a plurality of first electrode sub-groups. In an embodiment, each of the first electrode sub-groups includes at least one first sub-electrode. In an embodiment, in each of the at least one first touch electrode sub-unit, the first sub-electrodes of two adjacent first electrode sub-groups have gradually increasing lengths and gradually decreasing widths in a direction from one of the first connection portions closest to the first touch electrode sub-unit to the first touch electrode.

Abstract: A display panel and a display device are provided in the present disclosure. The display panel, including a display region and a non-display region, includes a first base substrate and a second base substrate. The display panel further includes a sealing adhesive between the first base substrate and the second base substrate. The sealing adhesive is disposed in the non-display region by surrounding the display region and includes a main body part and a plurality of first extension parts connected to the main body part. The plurality of the first extension parts is between the main body part and the display region. The display panel further includes a first reflective metal part in the non-display region, where at least a portion of the first reflective metal part surrounds the display region, and includes a plurality of second reflective metal parts, arranged along a first direction, in the non-display region.

Abstract: A display device and an electric apparatus are provided in the present disclosure. A touch unit of the display device includes a touch layer and an optical compensation layer arranged oppositely, the touch layer includes multiple first electrode groups and multiple second electrode groups, multiple second touch electrodes in the second electrode group are connected to each other through the optical compensation layer, and an orthographic projection of the optical compensation layer on a surface of the touch layer covers the touch layer, so that each position of the touch unit is a double-layer structure formed by the touch layer and the optical compensation layer, which avoids the problem that an electrode bridge in the display device may be visible in some cases caused by different light absorption levels in certain areas of the touch unit due to the different number of film layers.

Abstract: A display panel and a display device are provided. The display panel has a display region and a peripheral region surrounding the display region. The display panel includes: a scan driving circuit arranged in the peripheral region; a low-level voltage signal line arranged in the peripheral region and electrically connected to the scan driving circuit; an auxiliary metal line arranged in the peripheral region and electrically connected to the low-level voltage signal line. The peripheral region includes a first and second peripheral region located on opposite sides of the display region in a first direction, and a third and fourth peripheral region located on opposite sides of the display region in a second direction, the first direction being perpendicular to the second direction. The auxiliary metal line at least extends in the first, third and second peripheral region to form a structure partially surrounding the display region.
