The present disclosure provides a display panel and a display device. The display panel may be an organic light-emitting diode (OLED) display panel, or any another suitable type of display panel.
The display panel 100 may include data lines 10, sub-pixels 20, transfer lines 30 and demultiplexers 40. The data lines 10 may include a first data line 11 and a second data line 12, and the sub-pixels 20 may include a first sub-pixel 21 and a second sub-pixel 22.
A plurality of first data lines 11 and a plurality of first sub-pixels 21 may be located in the first area AA1, and the first data lines 11 may be connected to the first sub-pixels 21. The first data lines 11 may be used to transmit data line signals to the first sub-pixels 21.
A plurality of second data lines 12 and a plurality of second sub-pixels 22 may be located in the second area AA2, and the second data lines 12 may be connected to the second sub-pixels 22. The second data lines 12 may be used to transmit data signals to the second sub-pixels 22.
A plurality of transfer lines 30 may be located in the display area AA. Multiple transfer lines 30 may be connected to multiple first data lines 11 in a one-to-one correspondence.
The number of demultiplexers 40 may be greater than one. The demultiplexer 40 may include a number N of switches T, and the input terminals of the number N of switches T in a same demultiplexer 40 may be connected together.
The first data line 11 may be connected to the demultiplexer 40 through the transfer line 30. A number i of first data lines 11 and a number j of second data lines 12 may be connected to the output terminals of the number N of switches in the same demultiplexer 40 in a one-to-one correspondence. For the same demultiplexer 40, the light-emitting color of the first sub-pixels 21 connected to the number i of first data lines 11 may be same as the light-emitting color of the second sub-pixels 22 connected to the number j of second data lines 12. N≥2, and i+j=N. i, j, and N may be all integers, i≥1, and j≥1.
It should be noted that
In one embodiment, the number of the first edges L1 may be two, and the two first edges L1 may be opposite in the first direction X. The number of the first areas AA1 may be two, one of the first areas AA1 may be adjacent to one of the first edges L1, and the other first area AA1 may be adjacent to the other first edge L1. It can be understood that, in the first direction X, the first area AA1 may be located at the edge area of the display panel 100, and the second area AA2 may be located at the middle area of the display panel 100.
In one embodiment, the display panel 100 may further include a non-display area NA located on at least one side of the display area AA in the second direction Y, and the demultiplexers 40 may be located in the non-display area NA. The non-display area NA may also include a plurality of data signal terminals Source. The input terminals of multiple switches T in the same demultiplexer 40 may be connected to a same data signal terminal Source, and the output terminals of multiple switches T in the same demultiplexer 40 may be connected to different data lines. Multiple switches T in the demultiplexers 40 may be turned on sequentially such that the demultiplexers 40 may sequentially transmit the data signal provided from the same data signal terminal 50 to different data lines. The data signal terminal 50 may be connected to the driving chip, that is, the data signal may be provided by the driving chip.
Taking a white screen as an example, the data signals required by the sub-pixels of different light-emitting colors may be different. When the data signal terminal 50 provides data signals to the sub-pixels of different light-emitting colors, the data signal on the data signal terminal 50 may need to be continuously inverted. The more types of light-emitting colors of the sub-pixels connected to the same data signal terminal 50, the greater the signal inversion frequency of the data signal terminal 50 will be, resulting in greater power consumption of the driving chip.
The demultiplexer 40 may be connected to the driving chip through the data signal terminal 50. In one embodiment of the present disclosure, because for the data lines connected to the same demultiplexer 40, the light-emission color of the first sub-pixels 21 connected to the number of i first data lines 11 and the light-emitting color of the second sub-pixels 22 connected to the number j of second data lines 12 may be same such that the types of light-emitting colors of the sub-pixels connected to the data signal terminals 50 connected to the same demultiplexer 40 may be reduced. For example, when the white screen is displayed, the demultiplexers 40 may sequentially transmit the same data signal to the first data lines 11 and the second data lines 12. Therefore, the signal inversion frequency of the data signal terminal 50 connected to the demultiplexer 40 may be reduced. In another word, the signal inversion frequency of the driving chip may be reduced, or the driving signal may even not be inverted, which may be beneficial to reduce the power consumption of the driving chip.
In one embodiment, the display panel 100 may include a stepped area BA, a plurality of data signal terminals 50 may be disposed in the stepped area BA, and the data signal terminals 50 may be connected to a driving chip. In an actual application, the stepped area BA may be folded back to the non-light-emitting surface of the display panel to reduce the width of the lower frame of the display panel.
It should be noted that the configuration that the light-emission color of the first sub-pixels 21 connected to the number i of first data lines 11 is same as the light-emission color of the second sub-pixels 22 connected to the number of j of second data lines 12 is not used to limit that the first data line 11 may only be connected to the first sub-pixels 21 of one light-emitting color and the second data line 12 may only be connected to the second sub-pixels 22 of one light emitting color. For example, the light-emitting colors of the first sub-pixels 21 connected to the number i of first data lines 11 may include red and blue, and the light-emitting colors of the second sub-pixels 22 connected to the number j of second data lines 12 may also include red and blue. In such a configuration, it may also be considered that the light-emitting color of the first sub-pixels 21 connected to the number i of first data lines 11 is same as the light-emitting color of the second sub-pixels 22 connected to the number j of second data lines 12.
In the drawings of the present disclosure, sub-pixels filled with the same pattern may have the same light-emitting color, and sub-pixels filled with different patterns have different light-emitting colors.
In one embodiment, as shown in
The first sub-pixels 21 may include a first sub-pixel 21R emitting red light, a first sub-pixel 21G emitting green light, and a first sub-pixel 21B emitting blue light. The second sub-pixels 22 may include a second sub-pixel 22R emitting red light, a second sub-pixel 22G emitting green light, and a second sub-pixel 22B emitting blue light.
The first data line 11 connected to the first sub-pixel 21R, the first data line 11 connected to the first sub-pixel 21B, the second data line 12 connected to the second sub-pixel 22R, and the second data line 12 connected to the second sub-pixel 22B may be connected to different output terminals of the m-th demultiplexer 40(m). The input terminal of the m-th demultiplexer 40(m) may be connected to the m-th data signal terminal 50(m).
The first data line 11 connected to the first sub-pixel 21G and the second data line 12 connected to the second sub-pixel 22G may be connected to different output terminals of the n-th demultiplexer 40(n). The input terminal of the n-th demultiplexer 40(n) may be connected to the n-th data signal terminal 50(n).
As shown in

Referring to
In some embodiments, the number N of switches T in the demultiplexer 40 may be an even number, and i=j. For example, one half of the switches T in the demultiplexer 40 may be connected to the first data line 11, and the other half of the switches T in the demultiplexer 40 may be connected to the second data line 12. In such a configuration, the complexity of the driving sequence may be reduced, and the overall layout structure of the display panel may be simplified.
In one embodiment, the light-emitting colors of the first sub-pixels 21 in the first area AA1 include Q1 types, the light-emitting colors of the second sub-pixels 22 in the second area AA2 may include Q2 types, and the light-emitting colors of the first sub-pixels 21 may include Q11 types, and the light-emitting colors of the second sub-pixels 22 connected to the number j of second data lines 12 may also include Q11 types, Q11<Q1, and Q11<Q2.
For example, Q1=Q2=3, the light-emitting colors of the first sub-pixel 21 in the first area AA1 may include red, green and blue, and the light-emitting colors of the second sub-pixel 22 in the second area AA2 may also include red, green and blue.
In some optional embodiments, as shown in
A number i1 of first data lines 11 and a number j1 of second data lines 12 may be connected to the output terminals of the number N1 of switches in the same first demultiplexer 41 in a one-to-one correspondence, and for the same first demultiplexer 41, the light-emitting color of the first sub-pixel 21 connected with the number i1 of first data lines 11 may be same as the light-emitting color of the second sub-pixels 22 connected with the number j1 of second data lines 12, and i1+j1=N1.
A number i2 of first data lines 11 and a number j2 of second data lines 12 may be connected to the output terminals of N2 switches in the same second demultiplexer 42 in a one-to-one correspondence, and for the same second demultiplexer 42, the light-emitting colors of the first sub-pixels 21 connected with the number i2 of first data lines 11 may be same as the light-emitting color of the second sub-pixels 22 connected the number j2 of second data lines 12. N2≥2, and i2+j2=N2.
The light-emitting color of the first sub-pixels 21 connected to the number i1 of first data lines 11 corresponding to the first demultiplexer 41 may be different from the light-emitting color of the first sub-pixels 21 connected to the number i2 of first data lines 11 corresponding to the second demultiplexer 42. The light-emitting color of the second sub-pixels 22 connected to the number j1 of second data lines 12 corresponding to the first demultiplexer 41 may be different from the light-emitting color of the second sub-pixels 22 connected to the number j2 of second data lines 12 corresponding to the second demultiplexer 42. For example, the sub-pixels connected to the first demultiplexer 41 may have different light-emitting colors from the sub-pixels connected to the second demultiplexer 42. N1, N2, i1, i2, j1, and j2 may all be integers.
In one embodiment, the light-emitting colors of the sub-pixels connected to the first demultiplexer 41 may be different from the light-emitting colors of the sub-pixels connected to the second demultiplexer 42, which may be equivalent to assigning sub-pixels of multiple different light-emitting colors to different demultiplexers. In such a configuration, the first demultiplexer 41 and the second demultiplexer 42 may only need to provide the data signals required by the sub-pixels of a portion of the light-emitting colors. For example, the data signal terminals 50 connected to the first demultiplexer 41 and the second demultiplexer 42 may only need to provide the data signals required by the sub-pixels of some light-emitting colors such that the signal inversion frequency of the data signal terminals 50 connected to the demultiplexers 40 may be further reduced, thereby further reducing the signal inversion frequency of the driving chip.
In one embodiment, the light-emitting colors of the first sub-pixels 21 in the first area AA1 and the light-emitting colors of the second sub-pixels 22 in the second area AA2 may both include Q3 types, and the light-emitting colors of the sub-pixels connected to the first gate circuit 41 may include Q31 types, the sub-pixels connected to the second demultiplexer 42 may emit Q32 types of colors, Q31+Q32=Q3, and the colors in the Q31 types may be different from the colors in the Q32 types.
In some optional embodiments, i1=j1, i2=j2. In such a configuration, the number N1 of switches in the first demultiplexer 41 may be an even number, and the number N2 of switches in the second demultiplexer 42 may also be an even number. One half of the switches in the first demultiplexer 41 may be connected to the first data line 11, and the other half of the switches in the first demultiplexer 41 may be connected to the second data line 12. Similarly, one half of the switches in the second demultiplexer 42 may be connected to the first data line 11, and the other half of the switches in the second demultiplexer 42 may be connected to the second data line 12. Accordingly, the complexity of the driving sequence may be reduced, and the overall layout structure of the display panel may be simplified.
In some optional embodiments, i1=j1, i2=j2, and i1=i2, j1=j2. In such a configuration, N1=N2, and N1 and N2 are even numbers. Accordingly, it may be more conducive to reducing the complexity of the driving sequence, and more conducive to simplifying the overall layout structure of the display panel.
In some optional embodiments, i1=j1=2, i2=j2=2. In such a configuration, N1=N2=4. It may be understandable that the larger the numbers of N1 and N2 are, the more favorable the narrow frame design of the display panel may be. However, the larger the number of N1 and N2 is, the more unfavorable it is for the high refresh rate driver design. In the case of N1=N2=4, it may be beneficial to take into account both the narrow frame design of the display panel and the driving design of a high refresh rate.

The k-th first data line 11(k), the (k+1)-th first data line 11(k+1), the m-th second data line 12(m), and the (m+1)-th second data line 12(m+1) may be connected to the output terminals of the number N1 of switches in the same first demultiplexer 41 in a one-to-one correspondence, and the (k+2)-th first data line 11(k+2), the (k+3)-first data line 11(k+3), the (m+2)-th second data line 12(m+2) and the (m+3)-th second data line 12(m+3) and the output terminals of the number N2 of switches in a same second demultiplexer 42 may be connected in a one-to-one correspondence.
In one embodiment of the present disclosure, a column of sub-pixels may be configured with two data lines, and the odd-numbered and even-numbered rows of sub-pixels in a column of sub-pixels may be connected to different data lines. Two data lines may be used to transmit data signals to the same column of sub-pixels. Accordingly, it may be beneficial to realize the high refresh rate driving of the display panel.

In the embodiment of the present disclosure, only one data line is configured for a column of sub-pixels, which may reduce the number of data lines and may be beneficial to the high-resolution design of the display panel.
In some optional embodiments, the turn-on sequence of the two switches connected to the p-th first data line 11(p) and the (p+1)-th first data line 11(p+1) may be different from that of the two switches connected to the first second data line 12(s) and the (s+1)-th second data line 12(s+1).
For example, the display panel may include fifth and sixth control signal lines mux5 and mux6. As shown in
Because the p-th first data line 11(p) and the s-th second data line 12(s) may be connected to the first gate circuit 41, the (p+1)-th first data line 11(p+1) and the (s+1)-th second data line 12(s+1) may be connected to the second demultiplexer 42. Under the condition that the turn-on sequence of the two switches connected to the first data line 11(p) and the first data 11(p+1) may be different from the turn-on sequence of the two switches connected to the second data line 12(s) and the second data line 12(s+1), only arranging the control signal line mux5 and mux6 may allow the first demultiplexer 41 and the second demultiplexer 42 to perform a correct time-division transmission of the data signals.
In some optional embodiments, the two switches connected to the p-th first data line 11(p) and the (p+1)-th first data line 11(p+1) may be sequentially turned on according to the order of the first and the second; and the two switches connected to the s-th second data line 12(s) and the (s+1)-th second data line 12(s+1) may be turned on sequentially in the order of the second and the first.

In another embodiment, as shown in
As shown in
As shown in
In some optional embodiments, N1=N2=N3. In such a configuration, the complexity of the driving sequence may be reduced, and the overall layout structure of the display panel may be simplified.
For example, as shown in
In some optional embodiments, the switches in the first demultiplexer 41, the second demultiplexer 42 and the third demultiplexer 43 with the same turn-on order may be transistors of the same type, and the control signal lines connected to the switches with the same turn-on sequence in the first demultiplexer 41, the second demultiplexer 42 and the third demultiplexer 43 may be same. Such a configuration may reduce the number of control signal lines, may be beneficial to narrow bezels.
For example, the switches with the same turn-on sequence in the first demultiplexer 41, the second demultiplexer 42 and the third demultiplexer 43 may be all P-type transistors, or the switches with the same turn-on sequence in the first demultiplexer 41, the second demultiplexer 42 and the third demultiplexer 43 may be all N-type transistors.
For a P-type transistor, its turn-on level may be a low level, and its turn-off level may be a high level. For an N-type transistor, the turn-on level may be a high level and the turn-off level may be a low level.
In some embodiments, as shown in
By setting the first segment 31 in the second area AA2, and the first segment 31 and the second data line 12 connected to the same demultiplexer 40 adjacent to each other, the demultiplexer 40 may be connected to the first segment 31 and the second data line 12 through a connection line. The distances between the second data lines 12 may be similar, which may facilitate the arrangement of connection lines.
In one embodiment, the sub-pixels connected to the adjacent first segment 31 and the second data line 12 may emit light of a same color.
Orthographic projections of the first segment 31 and the second data line 12 on the light-emitting surface of the display panel may overlap or may not overlap.
For example, the orthographic projections of the first segment 31 and the second data line 12 on the light-emitting surface of the display panel may not overlap. In the first direction, the first segment 31 may be located between the second data line 12 and the second sub-pixels 22 connected by the second data line 12.
The present disclosure also provides a display device. The display device may include a present disclosed display panel, or other appropriate display panel.
Thus, according to the display panel and the display device provided by the embodiments of the present disclosure, for the data lines connected to the same demultiplexer, the light-emitting color of the first sub-pixels connected to the i-th first data line may be the same as that of the second sub-pixels connected to the j-th second data line may be same. Accordingly, the types of light-emitting colors of the sub-pixels connected to the data signal terminals connected to the demultiplexer may be reduced. For example, when displaying a white screen, the demultiplexer may sequentially transmit the same data signal to the first data line and the second data line. Therefore, the signal inversion frequency of the data signal terminal connected to the demultiplexer may be reduced, for example, the signal inversion frequency of the driving chip may be reduced or even no inversion for the driving chip, which may be beneficial to reducing the power consumption of the driving chip.
In accordance with the embodiments of the present disclosure as described above, these embodiments do not describe all details in detail, nor do they limit the disclosure to only the specific embodiments described. Obviously, many modifications and variations are possible in light of the above description. This description selects and specifically describes these embodiments to better explain the principles and practical applications of the present disclosure, such that those skilled in the art may make good use of the present disclosure and its modifications based on the present disclosure. This disclosure is to be limited only by the claims, along with their full scope and equivalents.
