All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a display panel, as shown in fig. 1, fig. 1 is a schematic cross-sectional structure diagram of the display panel provided in the embodiment of the present invention, and the display panel includes a first substrate 1 and a second substrate 2 that are oppositely disposed. The first substrate 1 has a plurality of first sub-pixels 11 on a side facing the second substrate 2, and the second substrate 2 has a plurality of second sub-pixels 21 on a side facing the first substrate 1.
In this embodiment, as shown in fig. 2 and fig. 3, fig. 2 is a schematic top view structure of a display panel according to an embodiment of the present invention, and fig. 3 is a schematic top view structure of another display panel according to an embodiment of the present invention, in a direction perpendicular to a plane of the second substrate 2, projections of the first sub-pixels 11 and the second sub-pixels 21 have no overlapping portion, and a projection of at least one first sub-pixel 11 on the second substrate 2 is located in a gap between two adjacent second sub-pixels 21.
Alternatively, as shown in fig. 2, only one projection of the first sub-pixel 11 on the second substrate 2 is located between two adjacent second sub-pixels 21, but the present invention is not limited thereto, and in another embodiment, as shown in fig. 3, there may also be two projections of the first sub-pixels 11 on the second substrate 2 located between two adjacent second sub-pixels 21, and of course, in other embodiments, there may also be more than two projections of the first sub-pixels 11 on the second substrate 2 located between two adjacent second sub-pixels 21. Specifically, the number of first sub-pixels 11 projected between two adjacent second sub-pixels 21 is set according to actual needs.
Further, as shown in fig. 3, the projection of the first sub-pixel 11 on the second substrate 2 may be located in a gap L1 extending between two adjacent second sub-pixels 21 along the column direction Y, although the invention is not limited thereto, and in other embodiments, the projection of the first sub-pixel 11 on the second substrate 2 may also be located in a gap L2 extending between two adjacent second sub-pixels 21 along the row direction X.
Further, a projection of the first sub-pixel 11 onto the second substrate 2 is provided in a gap L1 extending in the column direction Y or a gap L2 extending in the row direction X between any two adjacent second sub-pixels 21, or a projection of the first sub-pixel 11 onto the second substrate 2 is provided in a gap L1 extending in the column direction Y or a gap L2 extending in the row direction X in part of the array of second sub-pixels 21.
Based on this, even if the distance between the second sub-pixels 21 cannot be further reduced, the effect of providing sub-pixels between the adjacent second sub-pixels 21 can be visually achieved by projecting the first sub-pixels 11 located between the adjacent second sub-pixels 21, so that the number of sub-pixels displayed on the display screen can be increased, and the resolution of the display panel can be improved.
Alternatively, the first sub-pixel 11 includes a micro inorganic light emitting diode, and the second sub-pixel 21 includes an organic light emitting element. Because the shadow phenomenon of the mask can occur when the film layer is evaporated by the mask plate when the organic light-emitting element and the related film layer are manufactured, the distance between the organic light-emitting elements can not be further reduced, more organic light-emitting elements can not be arranged on the substrate with the fixed size, and the resolution of the display device where the organic light-emitting elements are positioned can not be further improved.
Therefore, in the embodiment of the invention, the first substrate 1 with the micro inorganic light emitting diode and the second substrate 2 with the organic light emitting element are combined together, so that the problem that the resolution of an organic light emitting display panel, namely an OLED display panel, is limited by a manufacturing process and cannot be further improved is solved, and the formed display panel has the advantages of lightness, thinness, high brightness and good picture visual effect of the OLED display panel and the LED display panel.

The first substrate 1 further has a plurality of first gate lines 13 and a plurality of first data lines 14, and the first driving circuit is electrically connected to the first gate lines 13 and the first data lines 14; the second substrate 2 further has a plurality of second gate lines 23 and a plurality of second data lines 24 thereon, and the second driving circuit is electrically connected to the second gate lines 23 and the second data lines 24.

The first pin 12 is electrically connected to the first driving circuit through the first data line 14 on the first substrate 1, and the second pin 22 is connected to the second driving circuit through the second data line 24 on the second substrate 2. After the first gate line 13 inputs a scan signal to the first driving circuit and the first data line 14 inputs a data signal to the first driving circuit, the thin film transistor T1 in the first driving circuit charges the micro light emitting diode through the first pixel electrode 111 electrically connected to the drain thereof, and drives the micro light emitting diode to emit light. When the second gate line 23 inputs a scan signal to the second driving circuit and the second data line 24 inputs a data signal to the second driving circuit, the thin film transistor T2 in the second driving circuit charges the organic light emitting element through the second pixel electrode 212 electrically connected to the drain electrode thereof, and drives the organic light emitting element to emit light.

For example, the first sub-pixel 11 includes a green sub-pixel G, and the second sub-pixel 21 includes a blue sub-pixel B and a red sub-pixel R.
When the micro light emitting diodes are formed on the first substrate 1 in the transfer integration manner, the yield is low, and compared with the formation of the micro light emitting diodes with multiple colors on the first substrate 1, the yield of the micro light emitting diodes with a single color formed on the first substrate 1 is high, so that the first sub-image 11 including the first sub-pixels with one color can not only improve the resolution of the display panel, but also improve the yield of the display panel.
Moreover, if the micro light emitting diodes with multiple colors are formed on the first substrate 1, multiple transportation is required, wherein only one color of micro light emitting diode can be transported in each transportation, so that, relatively speaking, only one color of micro light emitting diode is formed on the first substrate 1, the transportation times can be reduced, the manufacturing steps can be reduced, and the process can be simplified.
Of course, the present invention is not limited thereto, and in one embodiment of the present invention, the first sub-pixel 11 may include first sub-pixels of at least two colors; the second sub-pixel 21 may include at least three colors of second sub-pixels.

Based on this, the first sub-pixels 11 with three different colors on the first substrate 1 may form one pixel, and the second sub-pixels 2 with three different colors on the second substrate 2 may form one pixel, or one first sub-pixel 11 on the first substrate 1 and two second sub-pixels 21 with two different colors adjacent to the projection on the second substrate 2 may form one pixel, so that the resolution of the display panel may be further improved by the sub-pixels with the colors staggered on the first substrate 1 and the second substrate 2. Further optionally, the number of pixels on the first substrate 1 is the same as the number of pixels on the second substrate 2, that is, the resolution of the first substrate 1 is the same as the resolution of the second substrate 2, so that the resolution of the display panel can be doubled.
