Display panel and display device

A display device comprising a photosensitive device and a display panel, wherein the display panel comprises:

• a first display region;
• a component region surrounded by the first display region, wherein the component region comprises at least one transmission region and at least one second display region, one of the at least one transmission region is transparent and surrounded by the at least one second display region between the one of the at least one transmission region and the first display region, and the photosensitive device is disposed under the display panel in the one of the at least one transmission region;
• one or more sub-pixels disposed in each of the first display region and the second display region, wherein the one or more sub-pixels in each of the first display region and the second display region include red sub-pixels, green sub-pixels, and blue sub-pixels, the red sub-pixels in the first display region are arranged in a same red pixel arrangement as that in the second display region, the green sub-pixels in the first display region are arranged in a same green pixel arrangement as that in the second display region, and the blue sub-pixels in the first display region are arranged in a same blue pixel arrangement as that in the second display region;
• a black matrix layer disposed in the first and second display regions and not disposed in the light transmission region, wherein the black matrix layer comprises first openings respectively overlapping the one or more sub-pixels in the first display region and the one or more sub-pixels in the second display region and one or more second openings without overlapping the one or more sub-pixels in each of the first display region and the second display region;
• and
• touch wires disposed in the first display region and the second display region, and surrounding respective ones of the first openings and respective ones of the second openings,
• wherein the touch wires comprises:
• a row touch wire extending along a first direction parallel with a row direction of the display panel;
• a column touch wire extending along a second direction different from the first direction;
• first touch wires respectively arranged to enclose more than one of the first openings corresponding to ones of the one or more sub-pixels in each of the first display region and the second display region for emitting light of a same color in the first display region and the second display region;
• and second touch wires respectively arranged to enclose the second openings between adjacent two ones of the first touch wires, and
• wherein the first touch wires are spaced apart from each other and are electrically connected through the row touch wire and the column touch wire and the second touch wires are spaced apart from each other and are electrically connected through the row touch wire and/or the column touch wire with the first touch wire therebetween,
• wherein the first touch wire and the second touch wire are electrically connected through the row touch wire and/or the column touch wire.

A display panel comprising:

• a first display region;
• a component region surrounded by the first display region, wherein the component region comprises at least one transmission region and at least one second display region surrounding the transmission region and the at least one transmission region is transparent;
• one or more sub-pixels disposed in each of the first display region and the second display region, wherein the one or more sub-pixels in each of the first display region and the second display region include red sub-pixels, green sub-pixels, and blue sub-pixels, the red sub-pixels in the first display region are arranged in a same red pixel arrangement as that in the second display region, the green sub-pixels in the first display region are arranged in a same green pixel arrangement as that in the second display region, and the blue sub-pixels in the first display region are arranged in a same blue pixel arrangement as that in the second display region;
• a black matrix layer disposed in the first and second display regions and not disposed in the light transmission region, wherein the black matrix layer comprises first openings respectively overlapping the one or more sub-pixels in each of the first display region and the second display region and one or more second openings spaced apart from the first openings, wherein sub-pixels of the display panel including the one or more sub-pixels in each of the first display region and the second display region all are disposed outside the second opening in a plan view of the display panel;
• and
• touch wires disposed in the first display region and the second display region, and surrounding respective ones of the first openings and respective ones of the second openings,
• wherein the touch wires comprises:
• a row touch wire extending along a first direction parallel with a row direction of the display panel;
• a column touch wire extending along a second direction different from the first direction;
• first touch wires respectively arranged to enclose more than one of the first openings corresponding to ones of the one or more sub-pixels in the first display region and the one or more sub-pixels in the second display region for emitting light of a same color;
• and second touch wires respectively arranged to enclose the second openings between adjacent two ones of the first touch wires, and
• wherein the first touch wires are spaced apart from each other and are electrically connected through the row touch wire and the column touch wire and the second touch wires are spaced apart from each other and are electrically connected through the row touch wire and/or the column touch wire with the first touch wire therebetween,
• wherein the first touch wire and the second touch wire are electrically connected through the row touch wire and/or the column touch wire.
