Display panel and display device

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202411745657.0, filed on 2024 / 11 / 29 entitled "Display Panel and Display Device", the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0003] This disclosure relates to the field of display technology, and more particularly to a display panel and a display device. Background Technology

[0004] In related technologies, the display panel includes pixel driving circuits, light-emitting units, and data lines. The pixel driving circuits drive the light-emitting units to emit light, and the data lines provide data signals to the pixel driving circuits in the same column. In these technologies, multiple pixel driving circuits connected to the same data line drive light-emitting units of different colors. During solid-color display, because the pixel driving circuits scan line by line, the signals on the data lines need to transition between different data line signals. For example, when the first row of pixel driving circuits scans, the data line drives the blue light-emitting unit to emit light; when the second row of pixel driving circuits scans, the data line drives the red light-emitting unit to turn off. Therefore, the source driving circuit used to provide data signals to the data lines has high power consumption.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0062] The display panel includes multiple light-emitting units, among which are first light-emitting units, second light-emitting units, and third light-emitting units of different colors. The display panel includes a substrate, an electrode layer, a pixel defining layer, multiple pixel driving circuits (Pix), and multiple data lines (Da). The electrode layer is located on one side of the substrate and includes multiple electrode portions (Dx). Each electrode portion (Dx) forms a first electrode of a light-emitting unit. The orthographic projections of the multiple electrode portions (Dx) onto the substrate are arranged in an array along the row and column direction.

The first electrode portion (R) forms a first electrode of a first light-emitting unit, the second electrode portion (B) forms a first electrode of a second light-emitting unit, and the third electrode portion (G) forms a first electrode of a third light-emitting unit. The pixel defining layer is located on the side of the electrode layer opposite to the substrate. The pixel defining layer forms... There are multiple pixel openings, and the pixel openings and the electrode portions Dx are correspondingly arranged.

Multiple pixel driving circuits Pix are arrayed along the row and column direction. Each pixel driving circuit Pix includes a first pixel driving circuit Pix1, a second pixel driving circuit Pix2, and a third pixel driving circuit Pix3. The first pixel driving circuit Pix1 drives the first light-emitting unit to emit light, the second pixel driving circuit Pix2 drives the second light-emitting unit to emit light, and the third pixel driving circuit Pix3 drives the... The third light-emitting unit emits light; wherein, in the same row of pixel driving circuits Pix, the first pixel driving circuit Pix1, the second pixel driving circuit Pix2, the third pixel driving circuit Pix3, and the third pixel driving circuit Pix3 are alternately distributed in the row direction, and in at least one column of pixel driving circuits Pix, the first pixel driving circuit Pix1 and the second pixel driving circuit Pix2 are alternately distributed in the column direction; in the multiple electrode portions connected to the same row of pixel driving circuits Pix, the first electrode portion R, the third electrode portion G, the second electrode portion B, and the third electrode portion D are alternately distributed in the row direction X, and part of the column of electrode portions D are also alternately distributed. x forms a multi-color electrode array Vrb, and a portion of the column electrode array forms a monochromatic electrode array Vg.

The orthogonal projections of the plurality of data lines Da on the substrate extend along the column direction Y and are spaced apart along the row direction X. The data lines Da are connected to the pixel driving circuit Pix and are used to provide data signals to the pixel driving circuit Pix connected thereto.The plurality of data lines Da include a first data line Da1, a second data line Da2, and a third data line Da3. At least a portion of the first data lines Da1 are connected to a plurality of first pixel driving circuits Pix1 located in adjacent columns but different rows.

Furthermore, this pixel driving circuit arrangement in the display panel reduces the length of the electrode connection lines connecting the electrode section and the pixel driving circuit, thus facilitating electrode placement.

[0064] In this exemplary embodiment, at least a portion of the orthographic projection of the electrode portion Dx onto the substrate and the orthographic projection of the pixel driving circuit connected thereto onto the substrate do not overlap.

[0066] In this exemplary embodiment, as shown in Figures 1-5, in the first column pixel driving circuit, the first pixel driving circuit Pix1 and the second pixel driving circuit Pix2 are alternately distributed in the column direction Y.

[0074] In this exemplary embodiment, as shown in Figures 1-5, in the last column of pixel driving circuits, the third pixel driving circuit Pix3 and the first pixel driving circuit Pix1 are alternately distributed in the column direction Y. The first pixel driving circuit in the first column of pixel driving circuits and the first pixel driving circuit in the last column of pixel driving circuits are connected to the same first data line, that is, the first data line Da1 connected to the first pixel driving circuit in the first column of pixel driving circuits is connected to the first data line Da1 connected to the first pixel driving circuit in the last column of pixel driving circuits. This arrangement can reduce the number of source driving circuit output terminals, thereby saving energy.

[0075] In this exemplary embodiment, as shown in Figures 1-5, the electrode layer further includes an electrode connection line XL, which connects the pixel driving circuit Pix and the electrode portion Dx. The orthographic projection of the electrode connection line XL connected to the third electrode portion G in the (x+1)th column and (2y+2)th row of the electrode portion on the substrate lies between the orthographic projection of the second electrode portion B in the (x+2)th column and (2y+1)th row of the electrode portion on the substrate and the orthographic projection of the first electrode portion R in the (x+2)th column and (2y+3)th row of the electrode portion on the substrate.

This arrangement can reduce the number of source driving circuit output terminals, thereby saving energy.

[0090] In a traditional source driver circuit, the data signal output terminals are sequentially connected to the first data line, the third data line, the second data line, and the third data line along the row direction X. As shown in Figure 1, the orthographic projections of the first data line Da1, the second data line Da2, the third data line Da3, and the third data line Da3 on the substrate are alternately distributed along the row direction X. As shown in Figure 6, the orthographic projections of the third data line, the first data line, the second data line, and the third data line on the substrate are alternately distributed along the row direction X. Accordingly, the display panels shown in Figures 1 and 6 require jumpers to align the data lines with the data signal output terminals of the source driver circuit. Alternatively, the output order of the data signal output terminals in the source driver circuit can be changed.

[0091] It should be noted that, as shown in Figure 1-11, the black squares drawn on the data lines represent vias connecting the data lines to the pixel driving circuit, and the black squares drawn on the electrode layers represent vias connecting the electrode parts to the pixel driving circuit.
