Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2024-0028797, filed on February 28, 2024. BACKGROUNDTechnical field

[0002] The disclosure relates to a display device in which each of the pixel regions is electrically connected to a pad region through one of the connecting wirings. Description of the state of the art

[0003] In general, a display device provides an image to a user. The display device may, for example, contain multiple pixel regions. Each of the pixel regions may realize different colors. Each of the pixel regions may, for example, contain multiple sub-pixels. The sub-pixels in each pixel region may display different colors. Each of the pixel regions may, for example, contain a first sub-pixel and a second sub-pixel that displays a different color than the first sub-pixel.

[0004] The second subpixel of each pixel region can be controlled independently of the first subpixel of the corresponding pixel region. For example, the first subpixel of each pixel region can include a first driver circuit, while the second subpixel of each pixel region can include a second driver circuit. The first subpixel and the second subpixel of each pixel region can be controlled by different gate signals. For example, the first driver circuit of each pixel region can be electrically connected to a first gate line, while the second driver circuit of each pixel region can be electrically connected to a second gate line.

[0005] The pixel regions may be arranged between the first gate line and the second gate line. Consequently, the second driver circuit of each pixel region may have a different arrangement than the first driver circuit of the corresponding pixel region. For example, each of the first driver circuit and the second driver circuit in each pixel region may include a driver thin-film transistor, wherein a distance between the driver thin-film transistor of the second driver circuit and the second gate line may differ from a distance between the driver thin-film transistor of the first driver circuit and the first gate line. SHORT SUMMARY

[0006] In a display device, a coupling capacitance may occur between each driver circuit and the gate line electrically connected to the corresponding driver circuit. The coupling capacitance may be proportional to the distance between the driver thin-film transistor of each driver circuit and the gate line electrically connected to the corresponding driver circuit. Consequently, in the display device, the second sub-pixel of each pixel region may have a different coupling capacitance than the first sub-pixel of the corresponding pixel region. That is, in the display device, the light emitted by the second sub-pixel of each pixel region may have a different luminance than the light emitted by the first sub-pixel of the corresponding pixel region.

[0007] Therefore, according to the prior art display device, the quality of the image may decrease due to the deviation of the luminance of the light emitted from the sub-pixels in each pixel region.

[0008] Accordingly, the disclosure is directed to a display device that substantially obviates one or more problems due to the limitations and disadvantages of the prior art.

[0009] Various embodiments of the disclosure provide a display device that can reduce the deviation of the luminance of the light emitted from the sub-pixels of each pixel region.

[0010] Various embodiments of the disclosure provide a display device that can reduce the variation in the coupling capacitance of the sub-pixels in each pixel region.

The first electrode 310 of each sub-pixel R-SP, G-SP, W-SP, and B-SP may be partially exposed by the bank insulating layer 150. The bank insulating layer 150 may, for example, B. define an emission region R-EA, G-EA, W-EA and B-EA in each subpixel R-SP, G-SP, W-SP and B-SP.The light-emitting layer 320 and the second electrode 330 of each sub-pixel R-SP, G-SP, W-SP, and B-SP may be stacked on a portion of the first electrode 310 that overlaps the emission region R-EA, G-EA, W-EA, and B-EA of the corresponding sub-pixel R-SP, G-SP, W-SP, and B-SP. For example, the light-emitting layer 320 may be in direct contact with the first electrode 310 and the second electrode 330 in the emission region R-EA, G-EA, W-EA, and B-EA of each sub-pixel R-SP, G-SP, W-SP, and B-SP.

Therefore, in the display device according to the embodiment of the disclosure, an area of ​​each sub-pixel R-SP, G-SP, W-SP, and B-SP can be increased. For example, in the display device according to the embodiment of the disclosure, a size of the emission region R-EA, G-EA, W-EA, and B-EA defined in each sub-pixel R-SP, G-SP, W-SP, and B-SP can be increased.

[0100] Each of the sub-pixels R-SP, G-SP, W-SP, and B-SP may be electrically connected to the gate lines GL1 and GL2, unlike the sub-pixels R-SP, G-SP, W-SP, and B-SP that share the data lines DL1 and DL2 with the corresponding sub-pixels R-SP, G-SP, W-SP, and B-SP. For example, the red sub-pixel R-SP and the white sub-pixel W-SP of each pixel region PA may be electrically connected to one of the first gate lines GL1, while the green sub-pixel G-SP and the blue sub-pixel B-SP of each pixel region PA may be electrically connected to one of the second gate lines GL2. Consequently, in the display device according to the embodiment of the disclosure, the data signal can be applied to the sub-pixels R-SP, G-SP, W-SP, and B-SP of each pixel region PA simultaneously via the data lines DL1 and DL2.That is, in the display device according to the embodiment of the disclosure, the sub-pixels R-SP, G-SP, W-SP, and B-SP of each pixel region PA can be driven simultaneously. Therefore, in the display device according to the embodiment of the disclosure, the decrease in the driving speed due to the operation delay of each pixel region PA can be reduced or prevented.

[0101] The driver circuits R-DC, G-DC, W-DC, and B-DC and the emission region R-EA, G-EA, W-EA, and B-EA of each sub-pixel R-SP, G-SP, W-SP, and B-SP may be arranged adjacent to each other in the second direction Y. The driver circuits R-DC, G-DC, W-DC, and B-DC of each sub-pixel R-SP, G-SP, W-SP, and B-SP may be arranged close to the corresponding gate line GL1 and GL2.

For example, the green sub-pixel G-SP of each pixel region PA may be arranged between the red sub-pixel R-SP and the white sub-pixel W-SP of the corresponding pixel region PA, while the white sub-pixel W-SP of each pixel region PA may be arranged between the green sub-pixel G-SP and the blue sub-pixel B-SP of the corresponding pixel region PA. Consequently, in the display device according to the embodiment of the disclosure, a space for the driving circuits R-DC, G-DC, W-DC, and B-DC of each sub-pixel R-SP, G-SP, W-SP, and B-SP can be sufficiently secured.Therefore, in the display device according to the embodiment of the disclosure, the reduction in the area of ​​the emission regions R-EA, G-EA, W-EA and B-EA defined in each pixel region PA due to the driving circuits R-DC, G-DC, W-DC and B-DC of the corresponding pixel region PA can be reduced or minimized.

The white driving circuit W-DC of each pixel region PA may be arranged to be symmetrical to the red driving circuit R-DC of the corresponding pixel region PA with respect to the second direction Y, while the blue driving circuit B-DC of each pixel region PA may be arranged to be symmetrical to the green driving circuit G-DC of the corresponding pixel region PA with respect to the second direction Y.That is, in the display device according to the embodiment of the disclosure, the coupling capacitance of the white sub-pixel W-SP in each pixel region PA may be substantially the same as the coupling capacitance of the red sub-pixel R-SP in the corresponding pixel region PA, while the coupling capacitance of the blue sub-pixel B-SP in each pixel region PA may be substantially the same as the coupling capacitance of the green sub-pixel G-SP in the corresponding pixel region PA.
