As described above, data lines are separately arranged in each of the transparent area (TA) and the opaque area (OA), so that data driving for each of the transparent area (TA) and the opaque area (OA) can be provided independently.

FIG. 8 is a layout diagram of the common source driver 800 corresponding to the transparent area (TA) and the opaque area (OA) of the display panel 110 according to the present embodiments.

Referring to FIG. 8, the display device 100 according to the present embodiments is located or connected to the side non-display area (N/A) of the opaque area (OA) and has a first circuit portion ( 213) and a common source driver 800 that supplies a data voltage to each of the second circuit parts 223 of the opaque area OA.

As described above, by providing both data driving for each of the transparent area (TA) and the opaque area (OA) through the common source driver 800, efficient operation in each of the transparent area (TA) and the opaque area (OA) is provided. and can enable synchronized image display.

As described above, in order to provide data driving for each of the transparent area (TA) and the opaque area (OA) through the common source driver 800, the common source driver 800 is used for the transparent area (TA) and the opaque area (OA). All data voltages must be supplied to the data lines arranged in the area (OA).

Accordingly, all data lines arranged in the transparent area (TA) and the opaque area (OA) must be electrically connected to the common source driver 800.

FIG. 9 shows subpixels and data in each of the transparent area (TA) and opaque area (OA) of the display panel 110 when the common source driver 800 is disposed in the display device 100 according to the present embodiments. This is an example of line placement.

Referring to FIG. 9, one subpixel row in the transparent area TA may correspond to one subpixel row in the opaque area OA.

As described above, one subpixel row in the transparent area (TA) corresponds to one subpixel row in the opaque area (OA), thereby patterning the subpixels, signal lines such as data lines, etc. in the display panel 110. This can be relaxing.

Referring to FIG. 9, when one subpixel row in the transparent area (TA) corresponds to one subpixel row in the opaque area (OA), each subpixel row and the opaque area (OA) in the corresponding transparent area (TA) ), each subpixel row can receive a data voltage from the same data line (DL2r1, DL2g1, DL2b1, DL2r2, DL2g2, DL2b2, …) arranged from the transparent area (TA) to the opaque area (OA).

For example, a red subpixel row in the transparent area (TA) and a red subpixel row in the opaque area (OA) are the same data lines (DL2r1, DL2r2, . . . ) that are placed from the transparent area (TA) to the opaque area (OA). ) can receive data voltage from.

According to the above, in the transparent area TA, a smaller number of data lines are placed than in the opaque area OA, that is, by placing half the data lines compared to the opaque area OA, the aperture ratio and transparency are improved. It can be raised.

Referring to FIG. 10 , each subpixel row in the transparent area TA may receive a data voltage from the same data line as the most adjacent subpixel row of the same color among multiple subpixel rows in the opaque area OA.

For example, the red subpixel column SPC1r1 in the transparent area TA receives a data voltage from the same data line DL2r1 as the most adjacent red subpixel column SPC2r1 among multiple subpixel columns in the opaque area OA. is supplied. The green subpixel column SPC1g1 in the transparent area TA receives a data voltage from the same data line DL2g1 as the most adjacent green subpixel column SPC2g1 among the plurality of subpixel columns in the opaque area OA. The blue subpixel column SPC1b1 in the transparent area TA receives a data voltage from the same data line DL2b1 as the most adjacent blue subpixel column SPC2b1 among the plurality of subpixel columns in the opaque area OA.

According to the above, the length of the data lines (DL2r1, DL2g1, DL2b1, …) arranged from the opaque area (OA) to the transparent area (TA) can be minimized, and through this, the data voltage transmission delay can also be reduced. I can give it.

FIG. 11 shows subpixels and data in each of the transparent area (TA) and opaque area (OA) of the display panel 110 when the common source driver 800 is disposed in the display device 100 according to the present embodiments. This is another example of line placement.

Referring to FIG. 11, one subpixel column (SPC1r1) in the transparent area (TA) may correspond to three subpixel columns (SPC2r1, SPC2g1, and SPC2b1) in the opaque area (OA).

In this case, among the plurality of data lines (DL2r1, DL2g1, DL2b1, DL2r2, DL2g2, DL2b2, …) that supply data voltages to multiple subpixel columns in the opaque area (OA), 1/3 of the data lines (DL2r1, DL2g2, …) are placed from the opaque area (OA) to the transparent area (TA), and 2/3 of the data lines (DL2g1, DL2b1, DL2r2, DL2b2, …) can be placed only in the opaque area (OA). .

According to the above-mentioned, a smaller number of data lines are disposed in the transparent area TA than in the opaque area OA, that is, 1/3 of the data lines are disposed compared to the opaque area OA, thereby increasing the aperture ratio. and transparency can be further increased.

Referring to FIG. 11 , each subpixel row in the transparent area TA may receive a data voltage from the same data line as the most adjacent subpixel row of the same color among multiple subpixel rows in the opaque area OA.

For example, the red subpixel column SPC1r1 in the transparent area TA receives a data voltage from the same data line DL2r1 as the most adjacent red subpixel column SPC2r1 among multiple subpixel columns in the opaque area OA. is supplied. The green subpixel column SPC1g1 in the transparent area TA receives a data voltage from the same data line DL2g2 as the green subpixel column SPC2g2, which is the closest among multiple subpixel columns in the opaque area OA.
