[0002] Organic light-emitting display devices include self-luminous organic light-emitting diodes (OLEDs) and offer advantages such as fast response speed, high luminous efficiency, high brightness, and a wide viewing angle. These features not only include fast response speed, excellent luminous efficiency, high brightness, and a wide viewing angle, but also excellent contrast and color gamut because they can produce a perfect black grayscale.
[0003] Various studies are underway to ensure the aperture ratio of organic light-emitting display devices. However, due to the large amount of wiring required to drive the pixels, achieving a design that improves the aperture ratio is difficult. Furthermore, ensuring the aperture ratio is even more difficult when each pixel is composed of sub-pixels that emit four colors of light: red, green, blue, and white.

For ease of explanation, the proportions of each component shown in the accompanying drawings are different from their actual proportions, and therefore, the present disclosure is not limited to the proportions shown in the accompanying drawings.
[0067] Hereinafter, a display panel having an improved aperture ratio per pixel and a display device including the same according to some embodiments of the present disclosure will be described.
[0068] Figure 1 is a diagram schematically illustrating a configuration of a display device according to an embodiment of the present disclosure.
[0069] Reference Figure 1 A display device according to an embodiment of the present disclosure may include: a display panel 100, a display panel driving circuit for writing pixel data to pixels of the display panel 100, and a power supply 140 for generating power required to drive the pixels and the display panel driving circuit.
[0070] The display panel 100 may include a display area (active area) AA and a non-display (non-active area) NA.
[0071] The display panel 10 may include a substrate and a plurality of sub-pixels disposed on the substrate. In addition, the display panel 100 may further include various types of signal lines for driving the plurality of sub-pixels.
[0072] The display area AA may include a plurality of data lines DL transmitting data signals (also referred to as data voltages or image signals) and a plurality of gate lines GL transmitting gate signals (also referred to as scan signals).
[0073] The plurality of data lines and the plurality of gate lines may intersect each other. Each of the plurality of data lines may extend in a second direction (Y direction). Each of the plurality of gate lines may extend in a first direction (X direction). In this regard, the first direction may be a row direction, and the second direction may be a column direction. Alternatively, the first direction may be a column direction, and the second direction may be a row direction.
[0074] The non-display area NA may be an area outside the display area AA and may include a frame area. All or a portion of the non-display area NA may be visible to a viewer in front of the display device, or may be an area that is curved backward and therefore not visible to a viewer in front of the display device.
[0075] The display panel 100 may be a panel having a rectangular structure having a length in the X-axis direction or the first direction, a width in the Y-axis direction or the second direction, and a thickness in the Z-axis direction or the third direction. The X-axis and the Y-axis may be linear axes orthogonal to each other and may define an XY plane. The display area AA of the display panel 100 includes a pixel array that displays an input image. The pixel array includes a plurality of data lines DL, a plurality of gate lines GL that intersect the data lines DL, and pixels arranged in a matrix form. The display panel 100 includes a power supply line commonly connected to the pixels. The power supply line may be connected to a constant voltage node of a pixel circuit and provide the pixel PXL with a constant voltage required to drive the pixel PXL. The power supply line may be implemented as a strip or grid wiring and may be commonly connected to the pixels of the display panel 100.
[0076] Each pixel PXL includes a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel for emitting light of different colors, respectively, for color display. The arrangement of the first sub-pixel, the second sub-pixel, the third sub-pixel, and the fourth sub-pixel for emitting light of different colors, respectively, can be changed. The first sub-pixel can be a blue (B) sub-pixel, the second sub-pixel can be a green (G) sub-pixel, the third sub-pixel can be a red (R) sub-pixel, and the fourth sub-pixel can be a white (W) sub-pixel. However, the embodiments of the present disclosure are not limited to this. Each sub-pixel includes a pixel circuit for driving a light-emitting element. Each pixel circuit is connected to a data line, a gate line, and a power line. The area of each sub-pixel can be divided into a circuit area and a light-emitting area. The pixel circuit is arranged in the circuit area. The light-emitting area is an area where light is emitted from a light-emitting element electrically connected to the pixel circuit.
[0077] The pixel array includes a plurality of pixel rows L1 to LN. Each pixel row L1 to LN includes a row of pixels arranged along the row direction (X-axis direction) of the pixel array of the display panel 100. The pixels arranged in a pixel row share the same gate line GL. Subpixels arranged in the column direction Y along the data line direction share the same data line DL. One horizontal period is equivalent to one frame period divided by the total number of pixel rows L1 to LN.
[0078] The power supply 140 uses a DC-DC converter to output voltages required to drive the pixels of the display panel 100 and the display panel driving circuit. The DC-DC converter may include a charge pump, a regulator, a buck converter, a boost converter, and the like.
[0079] The display panel driving circuit writes pixel data of an input image into pixels of the display panel 100 under the control of the timing controller 130. The display panel driving circuit includes a data driver 110 and a gate driver 120.
[0080] The display panel driver circuit can drive pixels using a DRD (Double Rate Drive) scheme. In a display panel operating with the DRD scheme, data lines DL can be connected to adjacent sub-pixels in the left-right direction, thereby reducing the number of channels in the data driver 110 and the number of data lines DL. This helps ensure the pixel aperture ratio.
[0081] The display panel driving circuit may further include a touch sensor driver for driving the touch sensor. Figure 1 The touch sensor driver is omitted in FIG. The data driver 110 and the touch sensor driver may be integrated into one source driver IC (Integrated Circuit).
[0082] The data driver 110 receives pixel data of an input image as a digital signal from the timing controller 130 and outputs data voltages based on the pixel data. The data driver 110 may convert the pixel data of the input image into gamma-compensated data voltages using a DAC (digital-to-analog converter) and output the gamma-compensated data voltages during each frame period. The gamma-compensated data voltages are output from each channel of the data driver 110 via an output buffer.
[0083] The gate driver 120 and the TFT array and wiring of the pixel array may be formed in the display panel 100. The gate driver 120 may be disposed in the non-display area NA of the display panel 100, or at least a portion of the gate driver 120 may be disposed in the display area AA reproducing an input image.
[0084] The gate driver 120 may be disposed in a non-display area NA on each of opposite sides of the display panel 100, with the display area AA of the display panel 100 disposed between the gate drivers 120. The gate driver 120 may also be disposed at opposite ends of the gate lines GL, thereby supplying gate pulses to the gate lines GL using a dual-feed scheme. In another embodiment, the gate driver 120 may be disposed in either the left or right non-display area NA of the display panel 100 and may supply gate signals to the gate lines GL using a single-feed scheme. Under the control of the timing controller 130, the gate driver 120 sequentially outputs gate signal pulses to the gate lines. The gate driver 120 may sequentially supply gate signals to the gate lines GL by shifting the gate signal pulses (hereinafter referred to as gate pulses) using a shift register. The gate driver 120 may include a plurality of shift registers that output gate signal pulses.
[0085] The timing controller 130 receives digital video data of an input image and timing signals synchronized with the digital video data from the host system 200. Timing signals may include vertical synchronization signals, horizontal synchronization signals, a clock, and a data enable signal. Since the vertical and horizontal periods can be determined by counting the data enable signal, the vertical and horizontal synchronization signals may be omitted. The data enable signal has a duration of one horizontal period (1H). Based on the timing signals received from the host system 200, the timing controller 130 generates data timing control signals for controlling the operation timing of the data driver 110 and gate timing control signals for controlling the operation timing of the gate driver 120.
[0086] The timing controller 130 may add white data to the three-primary color pixel data RGB input from the host system to obtain four sub-color data RGBW, and transmit the four sub-color data RGBW to the data driver 110. A method for converting the three-primary color pixel data RGB into four sub-color data RGBW including white data may include a known color conversion algorithm. For example, the timing controller 130 may generate W data for the first pixel data based on the minimum grayscale value among the grayscale values of the R data, G data, and B data by mixing the R data, G data, and B data of the first pixel data received as input image data, and may convert the primary color pixel data RGB into four sub-color data RGBW based on the generated W data. Furthermore, the timing controller 130 may generate W data for the second pixel data received as input image data by mixing the R data, G data, and B data of the second pixel data received as input image data, and may convert the primary color pixel data RGB into four sub-color data RGBW based on the generated W data. Therefore, in each of the first pixel data and the second pixel data, the grayscale values of the R, G, and B data may be lowered by the grayscale value of the W data. In this regard, the R data may be data to be written to the red sub-pixel, the G data may be data to be written to the green sub-pixel, the B data may be data to be written to the blue sub-pixel, and the W data may be data to be written to the white sub-pixel.

The start pulse and the shift clock output from the level shifter 150 swing between a gate high voltage and a gate low voltage.

[0096] When a touch sensor is provided in the form of a panel outside the display panel 100, the touch sensor may be referred to as an external touch sensor. When the touch sensor is implemented as an external touch sensor, the touch panel and the display panel 100 may be manufactured separately and may be combined with each other during the assembly process.

However, the embodiments of the present disclosure are not limited thereto. The display device according to some embodiments of the present disclosure may be of various types and sizes capable of displaying information or images.
[0106] Figure 2 2 is a diagram schematically illustrating a first pixel and a second pixel according to an embodiment of the present disclosure. Pixels of a display panel may be arranged such that the first pixel and the second pixel are repeatedly arranged.
[0107] Reference Figure 2 The display panel 100 may include first and second pixels PXL1 and PXL2 that are arranged in a mirror-symmetrical structure around the Y axis and are adjacent to each other in the X axis direction as a first direction.
[0108] Each of the first pixel PXL1 and the second pixel PXL2 may include a first sub-pixel, a second sub-pixel, and a third sub-pixel for emitting light of different colors, respectively.
[0109] The first pixel PXL1 and the second pixel PXL2 may share a plurality of white sub-pixels.
[0110] The display panel 100 includes: a first data line pair DL10 arranged on the left side of the first pixel PXL1 and extending in the Y-axis direction; a second data line pair DL20 arranged between the first pixel PXL1 and the second pixel PXL1 and extending in the Y-axis direction; a third data line pair DL30 arranged on the right side of the second pixel PXL2 and extending in the Y-axis direction; a first power line PL10 arranged between the first data line pair DL10 and the second data line pair DL20 and extending in the Y-axis direction; and a second power line PL20 arranged between the second data line pair DL20 and the third data line pair DL30 and extending in the Y-axis direction.
[0111] Each of the first power lines PL10 and the second power lines PL20 may include a plurality of first power lines VL to which a pixel drive voltage EVDD is applied, and a second power line RL to which a reference voltage Vref is applied. The plurality of first power lines VL may be disposed on opposite sides of the second power line RL and connected to each other. Each of the plurality of first power lines VL may be wider than the second power line RL.
[0112] exist Figure 2In the embodiment, the first vertical reference line VR1 is an imaginary line parallel to the Y-axis direction and disposed between the first data line pair DL10 and the first power line PL10. The second vertical reference line VR2 is an imaginary line parallel to the Y-axis direction and disposed between the first power line PL10 and the second data line pair DL20. The third vertical reference line VR3 is an imaginary line parallel to the Y-axis direction and disposed between the second data line pair DL20 and the second power line PL20. The fourth vertical reference line VR4 is an imaginary line parallel to the Y-axis direction and disposed between the second power line PL20 and the third data line pair DL30.
[0113] First pixel PXL1 includes a blue subpixel, a green subpixel, and a red subpixel arranged along the Y-axis, such that a virtual first vertical reference line VR1 and a virtual second vertical reference line VR2 extend through the blue, green, and red subpixels. Second pixel PXL2 includes a blue subpixel, a green subpixel, and a red subpixel arranged along the Y-axis, such that a virtual third vertical reference line VR3 and a virtual fourth vertical reference line VR4 extend through the blue, green, and red subpixels. The blue subpixels of first pixel PXL1 and second pixel PXL2 are separated and spaced apart from each other. The green subpixels of first pixel PXL1 and second pixel PXL2 are separated and spaced apart from each other. The red subpixels of first pixel PXL1 and second pixel PXL2 are separated and spaced apart from each other. Independent R data can be written separately to first pixel PXL1 and second pixel PXL2. Independent G data can be written separately to first pixel PXL1 and second pixel PXL2. Independent B data can be written separately to first pixel PXL1 and second pixel PXL2.
[0114] The first pixel PXL1 and the second pixel PXL2 share a white sub-pixel, and the emission area EW of the white sub-pixel includes an area where the second and third vertical reference lines VR2 and VR3 intersect with a virtual fourth horizontal reference line HR4 .
[0115] Each of the first pixel PXL1 and the second pixel PXL2 can be operated in a 4-subpixel mode or a 3-subpixel mode. In the 4-subpixel mode, the 4 subpixels include a red subpixel, a green subpixel, a blue subpixel, and a shared white subpixel. In the 3-subpixel mode, the 3 subpixels include a red subpixel, a green subpixel, and a blue subpixel, but do not include a white subpixel.
[0116] When the first pixel PXL1 operates in a 4-subpixel mode, W data generated based on the R, G, and B data of the first pixel PXL1 is written to the white subpixel. When the second pixel PXL2 operates in a 4-subpixel mode, W data generated based on the R, G, and B data of the second pixel PXL2 is written to the white subpixel.
[0117] Each of the first pixel PXL1 and the second pixel PXL2 can operate in a hybrid mode. For example, when the first pixel PXL1 operates in a 4-subpixel mode, the second pixel PXL2 can operate in a 3-subpixel mode. When the second pixel PXL2 operates in a 4-subpixel mode, the first pixel PXL1 can operate in a 3-subpixel mode.
[0118] The timing controller 130 can analyze whether the input image is based on a pure color or analyze the saturation of the input image. When the saturation is greater than or equal to a predetermined reference value, the timing controller 130 can control the first pixel PXL1 and the second pixel PXL2 to operate simultaneously in a three-subpixel manner. In this case, the white subpixel does not operate.
[0119] The blue subpixel includes a first pixel circuit CB and a first light-emitting region EB connected to the first pixel circuit CB and emitting blue light. The green subpixel includes a second pixel circuit CG and a second light-emitting region EG connected to the second pixel circuit CG and emitting green light. The red subpixel includes a third pixel circuit CR and a third light-emitting region ER connected to the third pixel circuit CR and emitting red light. The white subpixel includes fourth pixel circuits CW1 and CW2, respectively disposed in the first and second pixels, and fourth light-emitting regions EW1 and EW2, respectively disposed in the first and second pixels and connected to the fourth pixel circuits CW1 and CW2, and emitting white light. The anode electrode of the light-emitting element EL may be disposed in each of the light-emitting regions EB, EG, ER, EW1, and EW2. Each of the pixel circuits CB, CG, CR, CW1, and CW2 may be connected to the anode electrode of a corresponding one of the light-emitting regions EB, EG, ER, EW1, and EW2. When current is generated by the driver element of the pixel circuit, the light-emitting region may emit light. The 4-1st light-emitting region EW1 is connected to the 4-1st pixel circuit CW1. The 4-2 th light emitting region EW2 is connected to the 4-2 th pixel circuit CW2 .
[0120] In the white sub-pixel, the fourth light emitting regions EW1 and EW2 may be operated under the control of two fourth pixel circuits CW1 and CW2, respectively. Figure 3 As shown in , the 4-1st pixel circuit CW1 and the 4-2nd pixel circuit CW2 may be connected to different gate lines, may sequentially receive gate pulses, and may drive light emitting elements of white sub-pixels.
[0121] In this regard, the fourth light emitting region EW may be formed as follows. Figure 2At this point, the fourth light emitting region EW includes fourth light emitting regions EW1 and EW2, and the fourth light emitting regions EW1 and EW2 include a 4-1st light emitting region EW1 and a 4-2nd light emitting region EW2 located in the first pixel PXL1 and the second pixel PLX2, respectively.
[0122] However, the embodiments of the present disclosure are not limited thereto. Figure 5 As shown in FIG, only one fourth light emitting region EW may be provided in the combination of the first pixel PXL1 and the second pixel PLX2. Only one fourth light emitting region EW may be provided in the combination of the third pixel PXL3 and the fourth pixel PXL4.
[0123] Or, as Figure 6 As shown in FIG, only one fourth light emitting region EW may be provided in only one of the first pixel PXL1 and the second pixel PLX2. Only one fourth light emitting region EW may be provided in only one of the third pixel PXL3 and the fourth pixel PXL4.
[0124] In the first pixel PXL1, the first pixel circuit CB, the left portion of the first emission region EB, the left portion of the second emission region EG, the second pixel circuit CG, and the left portion of the third emission region ER are arranged in this order along the first vertical reference line VR1.
[0125] In the first pixel PXL1, the 4-1st pixel circuit CW1, the right portion of the first light-emitting region EB, the right portion of the second light-emitting region EG, the third pixel circuit CR, the right portion of the third light-emitting region ER, and the 4-1st light-emitting region EW1 are arranged in this order along the second vertical reference line VR2.
[0126] In the second pixel PXL2, the 4-2nd pixel circuit CW2, the left portion of the first light-emitting region EB, the left portion of the second light-emitting region EG, the third pixel circuit CR, the left portion of the third light-emitting region ER, and the 4-2nd light-emitting region EW2 are arranged in this order along the third vertical reference line VR3.
[0127] In the second pixel PXL2, the first pixel circuit CB, the right portion of the first emission region EB, the right portion of the second emission region EG, the second pixel circuit CG, and the right portion of the third emission region ER are arranged in this order along the fourth vertical reference line VR4.
[0128] The arrangement of the different-colored light-emitting regions in first pixel PXL1 along the Y-axis direction can be similar to the arrangement of the different-colored light-emitting regions in second pixel PXL2 along the Y-axis direction. The light-emitting regions of the same color in first pixel PXL1 and second pixel PXL2 are arranged along the X-axis direction. For example, the first light-emitting regions EB of first pixel PXL1 and second pixel PXL2 are arranged along and overlap with a virtual first horizontal reference line HR1 parallel to the X-axis direction. The second light-emitting regions EG of first pixel PXL1 and second pixel PXL2 are arranged along and overlap with a virtual second horizontal reference line HR2 below the first light-emitting region EB in the Y-axis direction and parallel to the X-axis direction. The upper portions of the third light-emitting regions ER of first pixel PXL1 and second pixel PXL2 are arranged along and overlap with a virtual third horizontal reference line HR3 below the second light-emitting region EG in the Y-axis direction and parallel to the X-axis direction. The lower portions of the third emission regions ER of the first and second pixels PXL1 and PXL2, as well as the fourth emission regions EW1 and EW2, are arranged along a virtual fourth horizontal reference line HR4 below the third horizontal reference line HR3 in the Y-axis direction. In this regard, the first to fourth horizontal reference lines HR1 to HR4 are arranged in this order along the Y-axis direction. To improve the color gamut, the size of the third emission region ER, which generates red light, may be larger than each of the first and second emission regions EB and EG.
[0129] The fourth light emitting area EW generating white light is not continuous in the display panel 100 and is therefore provided in a disconnected or discontinuous manner on a pixel basis. This prevents white horizontal or vertical stripes from being visible to viewers when the entire display area AA of the display panel 100 displays a single color or a specific grayscale.
[0130] The third light-emitting region ER may be an L-shaped region with a quarter corner removed from the rectangle. The upper portion of the third light-emitting region ER in the column direction includes a smaller portion 20 adjacent to the upper end of the fourth light-emitting region EW in the column direction. The fourth light-emitting region EW is located within an area defined by removing a portion of the lower portion of the third light-emitting region ER of the first pixel PXL1 (overlapping with portion 20 in the column direction) and a portion of the lower portion of the third light-emitting region ER of the second pixel PXL1 (overlapping with portion 20 in the column direction), which are arranged in a mirror-symmetrical manner around the second data line pair DL20. In a plan view, the upper, left, and right sides of the combined fourth light-emitting regions EW1 and EW2 are surrounded by the third light-emitting regions ER of the first and second pixels PXL1 and PXL2. The third and fourth pixels PXL3 and PXL4 are arranged along the X-axis. The third and first pixels PXL1 are arranged along the Y-axis. The fourth and second pixels PXL4 are arranged along the Y-axis. That is, the first emission regions EB of the third pixel PXL3 and the fourth pixel PXL4 are respectively disposed below the fourth emission regions EW1 and EW2 of the first pixel PXL1 and the second pixel PXL2. The third pixel PXL3 and the fourth pixel PXL4 are adjacent to each other in the X-axis direction. Therefore, the fourth emission regions EW1 and EW2 of the first pixel PXL1 and the second pixel PXL2 are not adjacent to the fourth emission regions EW1 and EW2 of the third pixel PXL3 and the fourth pixel PXL4.
[0131] Power lines PL10 and PL20 can supply the constant voltage required to drive pixels PXL1 and PX2 to the pixel circuits CB, CG, CR, CW1, and CW2. The pixel drive voltage can be applied to the EVDD power line VL, and the reference voltage can be applied to the REF power line RL. The REF power line RL is arranged between the EVDD power lines VL, which have a relatively large width. The EVDD power line VL is connected to the adjacent pixel circuits CB, CG, CR, CW1, and CW2 and supplies the pixel drive voltage to the pixel circuits CB, CG, CR, CW1, and CW2. The REF power line RL can be arranged in the non-display area NA. The REF power line RL can be connected to the adjacent pixel circuits CB, CG, CR, CW1, and CW2 and supplies the pixel drive voltage to the pixel circuits CB, CG, CR, CW1, and CW2.
[0132] In each of the first pixel PXL1 and the second pixel PXL2, the power lines VL and RL may extend across the first light-emitting region EB, the second light-emitting region EG, and the third light-emitting region ER in a manner overlapping the first light-emitting region EB, the second light-emitting region EG, and the third light-emitting region ER. The power lines VL and RL may bypass the fourth light-emitting regions EW1 and EW2 and not overlap with the fourth light-emitting regions EW1 and EW2.
[0133] The first data line pair DL10 includes a first data line DLB1 to which a data voltage for B data is applied, and a second data line DLG1 to which a data voltage for G data is applied. The first data line DLB1 is positioned between the first pixel PXL1 and a pixel adjacent to it in the X-axis direction, and is commonly connected to the first pixel circuits CB of the first pixel PXL1 and the adjacent pixel. The first data line DLB1 supplies the data voltage for B data to the first pixel PXL1 and the adjacent pixel. The second data line DLG1 is positioned between the first pixel PXL1 and a pixel adjacent to it in the X-axis direction, and is commonly connected to the second pixel circuits CG of the first pixel PXL1 and the adjacent pixel. The second data line DLG1 supplies the data voltage for G data to the first pixel PXL1 and the adjacent pixel.
[0134] The first data line DLB1 is connected to a plurality of first pixel circuits CB arranged along the Y-axis direction. The first data line DLB1 transmits the data voltage for the B data to be written from the data driver 110 to the first pixel circuit CB. Only the data voltage for the B data is applied to the first data line DLB1. The second data line DLG1 is connected to a plurality of second pixel circuits CG arranged along the Y-axis direction. The second data line DLG1 transmits the data voltage for the G data to be written from the data driver 110 to the second pixel circuit CG. Only the data voltage for the G data is applied to the second data line DLG1.
[0135] The second data line pair DL20 includes a third data line DLR to which a data voltage of R data is applied, and a fourth data line DLW to which a data voltage of W data is applied. While the third data line DLR is disposed between the pixels PXL1 and PXL2, the third data line DLR is commonly connected to the third pixel circuits CR of the first pixel PXL1 and the second pixel PXL2 adjacent thereto in the X-axis direction, and while the third data line DLR is disposed between the pixels PXL1 and PXL2, the third data line DLR transmits the data voltage of R data to the third pixel circuits CR of the first pixel PXL1 and the second pixel PXL2 adjacent thereto in the X-axis direction. While the fourth data line DLW is disposed between the pixels PXL1 and PXL2, the fourth data line DLW is commonly connected to the fourth pixel circuits CW1 and CW2 of the first pixel PXL1 and the second pixel PXL2 adjacent thereto in the X-axis direction, and while the fourth data line DLW is disposed between the pixels PXL1 and PXL2, the fourth data line DLW transmits the data voltage of the W data to the fourth pixel circuits CW1 and CW2 of the first pixel PXL1 and the second pixel PXL2 adjacent thereto in the X-axis direction.
[0136] The third data line DLR is connected to a plurality of third pixel circuits CR arranged along the Y-axis direction. The third data line DLR transmits the data voltage for R data to be written from the data driver 110 to the third pixel circuits CR. Only the data voltage for R data is applied to the third data line DLR. The fourth data line DLW is connected to a plurality of fourth pixel circuits CW1 and CW2 arranged along the Y-axis direction. The fourth data line DLW transmits the data voltage for W data to be written from the data driver 110 to the fourth pixel circuits CW1 and CW2 for white subpixels. Only the data voltage for W data is applied to the fourth data line DLW.
[0137] The second data line pair DL20 extends through and overlaps the fourth emission region EW. The second data line pair DL20 may bypass other emission regions EB, EG, and ER and all pixel circuits CB, CG, CR, CW1, and CW2 so as not to overlap therewith.
[0138] The third data line pair DL30 includes a fifth data line DLB2 to which a data voltage for B data is applied, and a sixth data line DLG2 to which a data voltage for G data is applied. The fifth data line DLB2 receives only the data voltage for B data supplied from the data driver 110 to the blue subpixel. The sixth data line DLG2 receives only the data voltage for G data supplied from the data driver 110 to the green subpixel. While the fifth data line DLB2 is disposed between the second pixel PXL2 and a pixel adjacent thereto in the X-axis direction, the fifth data line DLB2 is commonly connected to the first pixel circuit CB of the second pixel PXL2 and the adjacent pixel. Furthermore, while the fifth data line DLB2 is disposed between the second pixel PXL2 and a pixel adjacent thereto in the X-axis direction, the fifth data line DLB2 supplies the data voltage for B data to the second pixel PXL2 and the first pixel circuit CB of the adjacent pixel. While the sixth data line DLG2 is arranged between the second pixel PXL2 and the pixel adjacent to it in the X-axis direction, the sixth data line DLG2 is commonly connected to the second pixel PXL2 and the second pixel circuit CG of the adjacent pixel, and while the sixth data line DLG2 is arranged between the second pixel PXL2 and the pixel adjacent to it in the X-axis direction, the sixth data line DLG2 supplies the data voltage of G data to the second pixel PXL2 and the second pixel circuit CG of the adjacent pixel.
[0139] A plurality of gate lines may extend along the first direction or the X-axis direction. Two gate lines sandwiching two light emitting regions (EB and EG or ER and EW) that respectively emit light of different colors and are adjacent to each other in the second direction Y may be connected to each other.
[0140] Each of the gate lines may extend along each pixel circuit row, and two gate lines adjacent to each other in the second direction Y may be commonly connected to a single output terminal of the gate driver 120. Figure 2 and Figure 3 As shown in , two gate lines sandwiching two light emitting areas that respectively emit light of different colors and are adjacent to each other in the second direction Y may be connected to each other and to a single output terminal of the gate driver 120. Therefore, a gate pulse may be applied to two pixel circuit rows at the same time. The n-th gate line GLn may simultaneously apply a gate pulse to the pixel circuits CB, CG, CR, CW1, and CW2 distributed on the two pixel circuit rows. Figure 2 , the connection between the pixel circuit CW2 and the n-th gate line GLn is omitted. Gate pulses may be sequentially applied to the gate lines GLn-1 to GLn+2 in the following order: GLn-1, GLn, GLn+1, and GLn+2.
[0141] Each of the scan lines SCn and SCn+1 for driving only the sensor transistor T2 of each of the first pixel PXL1 and the second pixel PXL2 may be disposed between two light emitting regions (EB and EG or ER and EW) that respectively emit light of different colors and between two gate lines GLn connected to each other.
[0142] That is, the nth scan line SCn may be disposed between the first and second emission regions EB and EG, respectively emitting light of different colors. The n+1th scan line SCn+1 may be disposed between the third and fourth emission regions ER and EW1 and EW2, respectively emitting light of different colors.
[0143] For example, in each of the first pixel PXL1 and the second pixel PXL2, the nth scan line SCn may be disposed between a first light emitting region EB and a second light emitting region EG that respectively emit light of different colors arranged along the Y-axis direction, and may be disposed between two gate lines of the nth gate line GLn extending in the first direction.
[0144] In addition, in each of the first pixel PXL1 and the second pixel PXL2, the n+1th scan line SCn+1 can be set between the third light-emitting region ER and the fourth light-emitting regions EW1 and EW2, which respectively emit light of different colors arranged along the Y-axis direction, and can be set between the two gate lines of the n+1th gate line GLn+1 extending in the first direction.
[0145] The first to third light emitting regions EB, EG, and ER of the first pixel PXL1 and the first to third light emitting regions EB, EG, and ER of the second pixel PXL2 may be arranged around the second data line pair DL20 in a mirror-symmetrical manner to each other.
[0146] The fourth emission regions EW1 and EW2 may be disposed between the third emission region ER of the first pixel PXL1 and the third emission region ER of the second pixel PXL2 arranged along the first direction X. The third emission region ER may constitute a third subpixel, and the fourth emission regions EW1 and EW2 may constitute a white subpixel.
[0147] The size of the light-emitting area of each sub-pixel emitting light of different colors can be appropriately set based on the color gamut and high brightness. For example, in an image model or display model that prioritizes high brightness over color gamut, the size of the light-emitting area of the fourth light-emitting area EW can be larger, and the driving voltage of each of the three sub-pixels except the white sub-pixel can be increased. Figure 2The structure of the third and fourth light-emitting regions ER and EW shown in the figure makes it easy to expand or reduce the size of the fourth light-emitting region EW in an elongated manner extending parallel to a horizontal reference line. Therefore, without changing the wiring shape, the sizes of the third and fourth light-emitting regions ER and EW can be easily controlled. In a display model that prioritizes pure colors (i.e., color gamut over high brightness), the size of the fourth light-emitting region EW can be reduced. To increase brightness, the size of the fourth light-emitting region EW can be increased.
[0148] Figure 3 It is shown in detail as Figure 2 : An equivalent circuit diagram of an example of a pixel circuit shown in . Figure 4 is a circuit diagram showing a unit pixel circuit.
[0149] Reference Figure 3 and Figure 4 Each of the pixel circuits CB, CG, CR, CW1 and CW2 is connected to a data line DL to which a data voltage Vdata of pixel data is applied, a gate line GL to which a gate pulse SCAN is applied, a power line VL to which a pixel driving voltage EVDD is applied, a power line to which a cathode voltage EVSS is applied, and a REF power line RL to which a reference voltage Vref is applied.
[0150] In the display panel 100 , a plurality of gate lines extend along a first direction, and two gate lines sandwiching two light emitting regions that respectively emit light of different colors and are adjacent to each other in a second direction Y may be connected to each other.
[0151] The display panel 100 has an nth scan line SCn and an n+1th scan line SCn+1, the nth scan line SCn is arranged between a first light-emitting region EB and a second light-emitting region EG, which respectively emit light of different colors and are adjacent to each other in the second direction Y, and the n+1th scan line SCn+1 is arranged between a third light-emitting region ER and fourth light-emitting regions EW1 and EW2, which respectively emit light of different colors and are adjacent to each other in the second direction Y.
[0152] Each of the nth scan line SCn and the (n+1)th scan line SCn+1 may be configured to apply a scan signal SCAN to drive only the sensor transistor T2 of each of the first pixel PXL1 and the second pixel PXL2 .
[0153] Each of the pixel circuits CB, CG, CR, CW1, and CW2 includes: a plurality of transistors DT, T1, and T2; and a capacitor C.
[0154] Each light-emitting region may include a light-emitting element EL, which may be implemented as an organic light-emitting diode (OLED) or an inorganic light-emitting element such as a Micro LED. The light-emitting element EL may include, but is not limited to, a red light-emitting element, a green light-emitting element, and a blue light-emitting element. The anode electrode of the light-emitting element EL is connected to the driving element DT and is disposed in the corresponding light-emitting region of each pixel. The light-emitting element EL operates based on the current generated by the driving element DT to emit light. Thus, light is guided out of the display panel 100 through the light-emitting region.
[0155] The driving element DT generates a current at a gate-source voltage to drive the light-emitting element EL. The driving element DT includes a gate electrode connected to a first node N1, a first electrode connected to a second node N2, and a second electrode connected to a third node N3. A capacitor C is connected to the first node N1 and the third node N3 and is disposed between the first node N1 and the third node N3. The second node N2 is connected to an EVDD power supply line VL. The third node N3 is connected to the anode electrode of the light-emitting element EL. The cathode electrode of the light-emitting element EL is connected to a power supply line to which a cathode voltage EVSS is applied.
[0156] The first switching element T1 is connected to the data line DL and the first node N1 and is disposed between the data line DL and the first node N1. The first switching element T1 can be, for example, a scan transistor. The first switching element T1 is turned on in response to a gate pulse SCAN. When the first switching element T1 is turned on, a data voltage Vdata of the pixel data is applied to the first node N1, so that the pixel data is written to the subpixel. The first switching element T1 includes a gate electrode connected to the gate line GL, a first electrode connected to the data line DL, and a second electrode connected to the first node N1.
[0157] The second switching element T2 is connected to the third node N3 and the REF power line RL and is disposed between the third node N3 and the REF power line RL. The second switching element T2 may be, for example, a sensor transistor. The second switching element T2 is turned on in response to a gate pulse SCAN.

The second switching element T2 includes a gate electrode connected to each of the scan lines SCn and SCn+1, a first electrode connected to the third node N3, and a second electrode connected to the REF power line RL.
[0158] The driving elements DT of all sub-pixels should have consistent electrical characteristics. However, due to process variations and component characteristic variations, the electrical characteristics of the driving elements DT of the sub-pixels may differ. These differences may increase as the operating time of each sub-pixel increases. To compensate for the differences in the electrical characteristics of the driving elements DT of the sub-pixels, an external compensation circuit may be applied to the display panel driver circuit.
[0159] exist Figure 3 For example, the nth scan line SCn may be connected to the gate electrode of the sensor transistor T2 of the first pixel circuit CB. The driving element DT may be connected to the first electrode of the sensor transistor T2 of the first pixel circuit CB. The REF power line RL may be connected to the second electrode of the sensor transistor T2 of the first pixel circuit CB.
[0160] In addition, the (n+1)th scan line SCn+1 is connected to the gate electrode of the sensor transistor T2 of the second pixel circuit CG. The driving element DT can be connected to the first electrode of the sensor transistor T2 of the second pixel circuit CG. The REF power line RL can be connected to the second electrode of the sensor transistor T2 of the second pixel circuit CG.
[0161] The external compensation circuit senses the electrical characteristics of the driving element DT in real time and compensates for the electrical characteristics of the driving element DT based on the sensing results in a sensing mode. The sensing mode may include a sensing mode before product shipment and a sensing mode after product shipment. In the sensing mode before product shipment, the external compensation circuit senses the electrical characteristics of the driving element DT in each sub-pixel via the REF power line RL connected to each sub-pixel and compensates for differences in the electrical characteristics of the driving element DT in each sub-pixel based on the sensing results.
[0162] The sensing mode after product shipment may include an ON RF mode performed in a power-up sequence, an RT mode performed during a vertical blank period of a display driving period, and an OFF RS mode performed in a power-down sequence.
[0163] In ON RF mode, when the display device is powered on, the external compensation circuit senses the mobility of the driver element DT, which drives the light-emitting element, via the REF power line RL in each subpixel. The external compensation circuit compares the mobility sensing result with the mobility compensation value of the driver element in each subpixel measured before product shipment, and updates the mobility compensation value based on the comparison result. In the pre-product sensing mode, the threshold voltage and mobility of the driver element DT in each subpixel are sensed, and the threshold voltage compensation value and mobility compensation value for the driver element are set in a lookup table. The external compensation circuit compensates the mobility of the driver element in each subpixel using the mobility compensation value based on the mobility sensing result of the driver element in each subpixel.
[0164] In RT mode, during the vertical blank period VB of each frame period during the display drive period in which an image is displayed, the external compensation circuit senses the mobility of the driving element DT of each subpixel in real time through the REF power line RL, and updates the mobility compensation value in each subpixel based on the mobility sensing result. The vertical blank period is a period between the active period of the N-1th frame period and the active period of the Nth frame period, during which no data is input to the timing controller 130.
[0165] In the OFF RS mode, when the display device is powered off, the external compensation circuit senses the threshold voltage of the driving element DT in each subpixel via the REF power line RL and updates the threshold voltage compensation value of the driving element DT in each subpixel based on the threshold voltage sensing result. In the OFF RS mode, the display panel drive circuit and the external compensation circuit operate for a preset delay time before power is completely turned off. The external compensation circuit senses the threshold voltage of the driving element DT in each subpixel and updates the threshold voltage compensation value of the driving element DT in each subpixel based on the threshold voltage sensing result.
[0166] The external compensation circuit includes an analog-to-digital converter (ADC) electrically connected to the REF power line (RL) and a compensation circuit for compensating the ADC data. The compensation circuit's lookup table stores compensation values for compensating the threshold voltage and mobility of the driver element driving the light-emitting element in each subpixel. The compensation circuit inputs sensing data output from the ADC into the lookup table and adds or multiplies the compensation value output from the lookup table with the pixel data of the input image to modulate the pixel data to compensate for variations in the electrical characteristics of the driver element. The ADC can be provided in each sensing channel group in the data driver 110 integrated with the source driver IC. The compensation circuit can be implemented as a logic circuit in the timing controller 130.
