Display module having insulation portion at front frame and display device having the same
View Patent ↗A display module and a display device are provided. The display module includes a display panel and a front frame. The display panel includes a display region and a non-display region both located at a side of a light emitting surface, wherein, the non-display region disposed at a peripheral area of the display panel and provided with a test pad electrically connected to wiring a of the display region. The front frame includes a front plate disposed opposite to at least a portion of the non-display region, and having an electric conduction portion for conducting away a current and an insulation portion for insulating the electric conduction portion from the test pad on the display panel. The present invention can avoid LCD screen noise and flicker because the test pad of the display panel contact with the front frame.
1. A display module comprising:
a display panel including:
a display region and a non-display region both located at a side of a light emitting surface, wherein, the non-display region disposed at a peripheral area of the display panel and provided with test pads electrically connected to wirings of the display region, wherein, the test pads includes a first test pad and a second test pad;
a first substrate provided with a first common electrode and a first wiring electrically connected to the first common electrode inside the display region, wherein, the first wiring electrically connects to the first test pad; and
a second substrate disposed opposite to the first substrate and provided with a second common electrode and a second wiring electrically connected to the second common electrode, wherein the second wiring electrically connects to the second test pad; and
a front frame including:
a front plate disposed opposite to at least a portion of the non-display region, and having:
a first insulation layer stacked disposition;
an electrically conductive film for conducting away a current, wherein, the electrically conductive film disposes at a side of the front plate adjacent to the non-display region; and
an opening formed through the electrically conductive film and aligned to the first and second test pads to reveal the first insulation layer such that the revealed first insulation layer is directly aligned to the first and second test pads, wherein,
when the front plate contacts with the non-display region of the display panel under an external force, the electrically conductive film cannot contact with the first and second test pads so as to insulate the electrically conductive film from the first and second test pads on the display panel.
2. The display module according to claim 1 , wherein, the display module further comprises a backlight module and the backlight module includes a backplane electrically connected to at least a portion of the electrically conductive film of the front frame to conduct away the current of the front frame.
3. A display module comprising:

a front frame including:
a front plate disposed opposite to at least a portion of the non-display region, and having:
a first insulation layer stacked disposition;
an electrically conductive film for conducting away a current, wherein, the electrically conductive film disposes at a side of the front plate adjacent to the non-display region; and
an opening formed through the electrically conductive film and aligned to the test pad to reveal the first insulation layer such that the revealed first insulation layer is directly aligned to the test pad for insulating the electrically conductive film from the test pad on the display panel.
6. The display device according to claim 5 , wherein, the test pad includes a first test pad and a second test pad, and the display panel comprises:
a first substrate provided with a first common electrode and a first wiring electrically connected to the first common electrode inside the display region, wherein, the first wiring electrically connects to the first test pad; and
a second substrate disposed opposite to the first substrate and provided with a second common electrode and a second wiring electrically connected to the second common electrode, wherein the second wiring electrically connects to the second test pad.
7. The display device according to claim 5 , wherein, the display module further comprises a backlight module, and the backlight module includes a backplane electrically connected to at least a portion of the electrically conductive film of the front frame to conduct away the current of the front frame.
