Abstract: A display device comprises a backlight module, a display panel and a first glue layer. The backlight module comprises a light guiding plate, a flexible reflecting sheet and a light source. The light guiding plate is provided with a light incoming face, a light outgoing face, a back face and a plurality of side faces. The flexible reflecting sheet is provided with a first area segment and a plurality of second area segments. The back face of the light guiding plate leans against the first area segment; the second area segments are connected to the first area segment and are bent relative to the first area segment; and at least part of the second area segments cover the side faces of the light guiding plate correspondingly. The light source is arranged on the flexible reflecting sheet and is aligned with the light incoming face of the light guiding plate. The light outgoing face faces the display panel. The display panel and the backlight module adhere to each other through the first glue layer. The first glue layer is located between the display panel and the second area segments of the flexible reflecting sheet. The invention also discloses an assembling method of the display device. Thus, the display device can achieve the frame narrowing function.

Abstract: The present invention teaches a touch display panel having a notch. A first resistance of a touch electrode is defined as the sum of a contact resistance between the touch electrode and the touch electrode's corresponding wire, and a resistance of the corresponding wire. For touch electrodes of an identical area, the touch electrodes have an identical first resistances. For touch electrodes of different areas, the touch electrodes of smaller areas have greater first resistances than those of the touch electrodes of greater areas. A consistent RC loading is obtained for touch electrodes of different areas, thereby effectively eliminating the touch and display differences resulted from the different areas of touch electrodes as the touch display panel has a notch design.

Abstract: The present disclosure relates to an in-cell touch display panel and an electronic device. The in-cell touch display panel includes a plurality of photo spacers (PSs) being configured to stand on the protection layer along an extending direction of the virtual lines, and the virtual lines are disconnected in standing locations of the PSs. The PSs avoid the metallic wiring layer, and the standing locations of PSs are more flat. As such, the supporting height of the PSs are the same, and the cell thickness is uniform. The dark stripe issue caused by the configuration of the PSs may be avoided, and so does the un-recoverable Push Mura, water ripple, and bright and dark spots. At the same time, the surface pressure and the display performance of the in-cell touch display panel may be enhanced.

The signal transmission circuits include a first signal transmission circuit and a second signal transmission circuit in the circuit region. The second signal transmission circuit and the control signal circuit are disposed at the same layer. Therefore, there is no need to provide a hole for electrical connection between second signal transmission circuit and control signal circuit in the circuit region. The density of the holes in the circuit region is reduced.
