[0164] This disclosure will now be described in more detail with reference to the following embodiments. It should be noted that the following description of some embodiments presented herein is for illustrative and descriptive purposes only. It is not exhaustive or limited to the precise forms disclosed.
[0165] This disclosure provides, in particular, an array substrate and a display device that substantially eliminates one or more problems caused by the limitations and disadvantages of the prior art. In one aspect, this disclosure provides an array substrate. In some embodiments, the array substrate includes: a plurality of pixel driving circuits; a plurality of light-emitting elements; a plurality of data lines configured to provide data signals to the plurality of pixel driving circuits; and a plurality of voltage supply lines extending in a display area of the array substrate and configured to provide voltage supply signals to the cathodes of the plurality of light-emitting elements. Optionally, the layer containing the plurality of voltage supply lines is located on the side of the plurality of data lines adjacent to the active layer of the plurality of pixel driving circuits, or the plurality of voltage supply lines and the plurality of data lines are located on the same layer.
[0166] Various suitable pixel driving circuits can be used in the array substrate of this disclosure. Examples of suitable driving circuits include 3T1C, 2T1C, 4T1C, 4T2C, 5T2C, 6T1C, 7T1C, 7T2C, 8T1C, and 8T2C. In some embodiments, each pixel driving circuit in a plurality of pixel driving circuits is an 8T1C driving circuit. Various suitable light-emitting elements can be used in the array substrate of this disclosure. Examples of suitable light-emitting elements include organic light-emitting diodes (OLEDs), quantum dot OLEDs, and micro-LEDs. Optionally, the light-emitting element is a micro-LED. Optionally, the light-emitting element is an organic light-emitting diode including an organic light-emitting layer.

Each subpixel includes electronic components such as a light-emitting element. In one example, the light-emitting element is driven by a respective pixel driving circuit PDC. The array substrate includes a plurality of first gate lines (e.g., each first gate line GL1), a plurality of second gate lines (e.g., each second gate line GL2), a plurality of data lines (e.g., each data line DL), a plurality of power lines (e.g., each power line Vdd), and a plurality of voltage supply lines (e.g., each voltage supply line Vss).

In one example, a high voltage signal (e.g., a VDD signal) is input to the corresponding pixel driving circuit PDC connected to the anode of the light-emitting element via each of the plurality of power lines Vdd; a low voltage signal (e.g., a VSS signal) is input to the cathode of the light-emitting element via the voltage supply lines. The voltage difference between the high voltage signal (e.g., the VDD signal) and the low voltage signal (e.g., the VSS signal) is the driving voltage ΔV that drives the light-emitting element to emit light.
[0168] Figure 2A This is a circuit diagram illustrating the structure of a pixel driving circuit according to some embodiments of the present disclosure. (Refer to...) Figure 2AIn some embodiments, the pixel driving circuit includes: a driving transistor Td; a storage capacitor Cst having a first capacitor electrode Ce1 and a second capacitor electrode Ce2; a second reset transistor Tr2 having a gate connected to a corresponding second reset control signal line rst2 among a plurality of second reset control signal lines, a first electrode connected to a corresponding second reset signal line Vint2 among a plurality of second reset signal lines, and a second electrode connected to a second electrode of the driving transistor Td; a first transistor T1 having a gate connected to a corresponding first gate line GL1 among a plurality of first gate lines, a first electrode connected to a corresponding data line DL among a plurality of data lines, and a second electrode connected to a first electrode of the driving transistor Td; a third reset transistor Tr3 having a gate connected to a corresponding first reset control signal line rst1 among a plurality of first reset control signal lines, a first electrode connected to a corresponding third reset signal line Vint3 among a plurality of third reset signal lines, and a second electrode connected to a first electrode of the driving transistor Td; and a second transistor T2 having a gate connected to a corresponding second gate line among a plurality of second gate lines. The transistor comprises: a gate of line GL2; a first electrode connected to the first capacitor electrode Ce1 of the storage capacitor Cst and the gate of the driving transistor Td; and a second electrode connected to the second electrode of the driving transistor Td; a third transistor T3 having a gate connected to a corresponding light-emitting control signal line em among a plurality of light-emitting control signal lines; a first electrode connected to a corresponding power line Vdd among a plurality of power lines; and a second electrode connected to the first electrode of the driving transistor Td and the second electrode of the first transistor T1; a fourth transistor T4 having a gate connected to a corresponding light-emitting control signal line em among a plurality of light-emitting control signal lines; a first electrode connected to the second electrode of the driving transistor Td and the second electrode of the second transistor T2; and a second electrode connected to the anode of the light-emitting element LE; and a first reset transistor Tr1 having a gate connected to a corresponding first reset control signal line rst1 among a plurality of first reset control signal lines; a first electrode connected to a corresponding first reset signal line Vint1 among a plurality of first reset signal lines; and a second electrode connected to the second electrode of the fourth transistor T4 and the anode of the light-emitting element LE. A second capacitor electrode Ce2 is connected to the corresponding power line and the first electrode of the third transistor T3.
[0169] In some embodiments, the pixel driving circuit includes a driving transistor Td, a data writing transistor (e.g., a first transistor T1), a compensation transistor (e.g., a second transistor T2), two light-emitting control transistors (e.g., a third transistor T3 and a fourth transistor T4), and three reset transistors (e.g., a first reset transistor Tr1, a second reset transistor Tr2, and a third reset transistor Tr3).
[0170] As used herein, a first electrode or a second electrode refers to one of a first terminal and a second terminal of a transistor, wherein the first terminal and the second terminal are connected to the active layer of the transistor. The direction of current flow through the transistor can be configured from the first electrode to the second electrode, or from the second electrode to the first electrode. Thus, depending on the direction of current flow through the transistor, in one example, the first electrode is configured to receive an input signal and the second electrode is configured to output an output signal; in another example, the second electrode is configured to receive an input signal and the first electrode is configured to output an output signal.
[0171] The pixel driving circuit also includes a first node N1, a second node N2, a third node N3, and a fourth node N4. The first node N1 is connected to the gate of the driving transistor Td, the first capacitor electrode Ce1, and the first electrode of the second transistor T2. The second node N2 is connected to the second electrode of the third transistor T3, the second electrode of the first transistor T1, the second electrode of the third reset transistor Tr3, and the first electrode of the driving transistor Td. The third node N3 is connected to the second electrode of the driving transistor Td, the second electrode of the second transistor T2, the first electrode of the fourth transistor T4, and the second electrode of the second reset transistor Tr2. The fourth node N4 is connected to the second electrode of the fourth transistor T4, the second electrode of the first reset transistor Tr1, and the anode of the light-emitting element LE.
[0172] In some embodiments, the array substrate includes a plurality of sub-pixels. In some embodiments, the plurality of sub-pixels includes each first sub-pixel, each second sub-pixel, and each third sub-pixel. Optionally, each pixel of the array substrate includes a corresponding first sub-pixel, a corresponding second sub-pixel, and a corresponding third sub-pixel. The plurality of sub-pixels in the array substrate are arranged in an array. In one example, the array of the plurality of sub-pixels includes a repeating array of the form S1-S2-S3, where S1 represents each first sub-pixel, S2 represents each second sub-pixel, and S3 represents each third sub-pixel. In another example, the S1-S2-S3 form is a C1-C2-C3 form, where C1 represents each first sub-pixel of a first color, C2 represents each second sub-pixel of a second color, and C3 represents each third sub-pixel of a third color. In another example, the C1-C2-C3 form is an RGB form, where each first sub-pixel is a red sub-pixel, each second sub-pixel is a green sub-pixel, and each third sub-pixel is a blue sub-pixel.
[0173] In another example, the array of multiple sub-pixels includes a repeating array of the form S1-S2-S3-S4, where S1 represents each first sub-pixel, S2 represents each second sub-pixel, S3 represents each third sub-pixel, and S4 represents each fourth sub-pixel. In another example, the S1-S2-S3-S4 form is C1-C2-C3-C4, where C1 represents each first sub-pixel of a first color, C2 represents each second sub-pixel of a second color, C3 represents each third sub-pixel of a third color, and C4 represents each fourth sub-pixel of a fourth color. In yet another example, the S1-S2-S3-S4 form is C1-C2-C3-C2', where C1 represents each first sub-pixel of a first color, C2 represents each second sub-pixel of a second color, C3 represents each third sub-pixel of a third color, and C2' represents each fourth sub-pixel of a second color. In another example, the C1-C2-C3-C2' form is RGBG, where each first subpixel is a red subpixel, each second subpixel is a green subpixel, each third subpixel is a blue subpixel, and each fourth subpixel is a green subpixel.
[0174] In some embodiments, the smallest repeating unit of the plurality of sub-pixels of the array substrate includes a corresponding first sub-pixel, a corresponding second sub-pixel, and a corresponding third sub-pixel. Optionally, each of the first sub-pixel, the second sub-pixel, and the third sub-pixel includes a first transistor T1, a second transistor T2, a third transistor T3, a fourth transistor T4, a first reset transistor Tr1, a second reset transistor Tr2, a third reset transistor Tr3, a driving transistor Td, and a storage capacitor Cst.
[0175] In an alternative embodiment, the smallest repeating unit of the plurality of sub-pixels of the array substrate includes a corresponding first sub-pixel, a corresponding second sub-pixel, a corresponding third sub-pixel, and a corresponding fourth sub-pixel. Optionally, each of the first sub-pixel, the second sub-pixel, the third sub-pixel, and the fourth sub-pixel includes a first transistor T1, a second transistor T2, a third transistor T3, a fourth transistor T4, a first reset transistor Tr1, a second reset transistor Tr2, a third reset transistor Tr3, a driving transistor Td, and a storage capacitor Cst.
[0176] This disclosure can be implemented in pixel driving circuits having various types of transistors, including pixel driving circuits having p-type transistors, pixel driving circuits having n-type transistors, and pixel driving circuits having one or more p-type transistors and one or more n-type transistors. (See also...) Figure 2AThe second transistor T2 is an n-type transistor, such as a metal-oxide-semiconductor (MOS) transistor, while the other transistors are p-type transistors, such as polysilicon transistors. For p-type transistors, the active control signal (e.g., the turn-on control signal) is a low-voltage signal, while the inactive control signal (e.g., the turn-off control signal) is a high-voltage signal. For n-type transistors, the active control signal (e.g., the turn-on control signal) is a high-voltage signal, while the inactive control signal (e.g., the turn-off control signal) is a low-voltage signal.
[0177] Figure 2B This is a timing diagram illustrating the operation of a pixel driving circuit according to some embodiments of the present disclosure. (Refer to...) Figure 2A and Figure 2B During one frame of an image, the operation of the pixel driving circuit includes a reset sub-stage t1, a data writing sub-stage t2, and a light emission sub-stage t3. In the initial sub-stage t0, a cutoff reset control signal is provided to the gate of the second reset transistor Tr2 via the corresponding second reset control signal line rst2, causing the second reset transistor Tr2 to turn off. A cutoff reset control signal is provided to the gates of the first reset transistor Tr1 and the third reset transistor Tr3 via the corresponding first reset control signal line rst1, causing the first reset transistor Tr1 and the third reset transistor Tr3 to turn off. In the initial sub-stage t0, a cutoff signal is provided to the corresponding first gate line GL1, therefore the first transistor T1 is turned off.
[0178] In reset phase t1, the turn-on reset control signal is provided to the gate of the first reset transistor Tr1 via the corresponding first reset control signal line rst1, turning on the first reset transistor Tr1; this causes the initialization voltage signal from the corresponding first reset signal line Vint1 to be transmitted from the first electrode of the first reset transistor Tr1 to the second electrode of the first reset transistor Tr1; and then to node N4. The anode of the light-emitting element LE is initialized. The turn-on reset control signal is provided to the gate of the third reset transistor Tr3 via the corresponding first reset control signal line rst1, turning on the third reset transistor Tr3; this causes the initialization voltage signal from the corresponding third reset signal line Vint3 to be transmitted from the first electrode of the third reset transistor Tr3 to the second electrode of the third reset transistor Tr3; and then to node N2. Node N2 is initialized. The second capacitor electrode Ce2 receives a high voltage signal from the corresponding power supply line Vdd. Due to the increased voltage difference between the first capacitor electrode Ce1 and the second capacitor electrode Ce2, the first capacitor electrode Ce1 is charged in reset phase t1. During the reset phase t1, a cutoff signal is provided to the corresponding first gate line GL1, thus turning off the first transistor T1. A high voltage signal is provided to the corresponding light-emitting control signal line em, causing the third transistor T3 and the fourth transistor T4 to turn off.
[0179] During the data writing sub-stage t2, a turn-on reset control signal is provided to the gate of the second reset transistor Tr2 via the second reset control signal line rst2, turning on the second reset transistor Tr2. This causes the initialization voltage signal from the corresponding second reset signal line Vint2 to be transmitted from the first electrode of the second reset transistor Tr2 to its second electrode, and then to the second electrode of the driving transistor Td. The second electrode of the driving transistor Td is then initialized.
[0180] During the data write sub-stage t2, the cutoff reset control signal is again provided to the gates of the first reset transistor Tr1 and the third reset transistor Tr3 via the corresponding first reset control signal line rst1, causing the first reset transistor Tr1 and the third reset transistor Tr3 to be turned off. The corresponding first gate line GL1 and the corresponding second gate line GL2 are provided with conduction signals, thus turning on the first transistor T1 and the second transistor T2. The first electrode of the driving transistor Td is connected to the second electrode of the second transistor T2. The gate of the driving transistor Td is electrically connected to the first electrode of the second transistor T2. Because the second transistor T2 is turned on during the data write sub-stage t2, the gate and second electrode of the driving transistor Td are connected and short-circuited, so only the PN junction between the gate and the first electrode of the driving transistor Td is effective, thus putting the driving transistor Td in diode connection mode. The first transistor T1 is turned on during the data write sub-stage t2. The data voltage signal transmitted via the corresponding data line DL is received by the first electrode of the first transistor T1 and then transmitted to the first electrode of the driving transistor Td, which is connected to the second electrode of the first transistor T1. Node N2, connected to the first electrode of the driving transistor Td, has a data voltage signal level. Because only the PN junction between the gate of the driving transistor Td and the first electrode is active, the voltage level of node N1 gradually increases to (Vdata + Vth) during the data write sub-stage t2, where Vdata is the data voltage signal level and Vth is the threshold voltage Th of the PN junction. Because the voltage difference between the first capacitor electrode Ce1 and the second capacitor electrode Ce2 decreases to a relatively small value, the storage capacitor Cst discharges. The corresponding light-emitting control signal line em is provided with a high voltage signal to turn off the third transistor T3 and the fourth transistor T4.
[0181] In the light-emitting phase t3, a cutoff reset control signal is provided to the gate of the second reset transistor Tr2 via the corresponding second reset control signal line rst2, causing the second reset transistor Tr2 to turn off. A cutoff reset control signal is also provided to the gates of the first reset transistor Tr1 and the third reset transistor Tr3 via the corresponding first reset control signal line rst1, causing both the first and third reset transistors Tr1 and Tr3 to turn off. Cutoff signals are provided to the corresponding first gate line GL1 and the corresponding second gate line GL2, thus turning off the first transistor T1 and the second transistor T2. A low voltage signal is provided to the corresponding light-emitting control signal line em, causing the third transistor T3 and the fourth transistor T4 to turn on. In the light-emitting phase t3, the voltage level of node N1 is maintained at (Vdata + Vth), and the driving transistor Td is turned on by this voltage level and operates in the saturation region. A path is formed through the third transistor T3, the driving transistor Td, and the fourth transistor T4 to the light-emitting element LE. The driving transistor Td generates a driving current for driving the light-emitting element LE to emit light. The voltage level at node N3, which is connected to the second electrode of the driving transistor Td, is equal to the emission voltage of the light-emitting element LE.
