The embodiment of the application provides a display panel, as shown in fig. 1 and fig. 2, the display panel includes a backlight module 100 and a display module 200 which are stacked.
The display module 200 is divided into a first display area a and a second display area B, and the second display area B includes a plurality of liquid crystal sub-pixels 2. The first display region a includes a plurality of organic light emitting sub-pixels 1. Fig. 8 is an arrangement pattern of a plurality of organic light emitting cells 12 in the first display region a, and as shown in fig. 8, at least a part of the organic light emitting cells 12 of the organic light emitting sub-pixel 1 includes a light emitting region 121 and a transparent region 122.

It should be noted that, in fig. 1, the area defined by the box a is the first display area a, and the area defined by the box B is the second display area B; in fig. 2, the area defined by the box a is a first display area a, and the area outside the box a is a second display area B. The structure and the light Emitting principle of the organic light Emitting sub-pixel 1 of the first display area a are similar to those of sub-pixels in an OLED (organic light-Emitting Diode) display panel in the art; the structure and the light emitting principle of the Liquid Crystal sub-pixel 2 of the second Display region B are similar to those of the sub-pixel of the LCD (Liquid Crystal Display) in the art.
The shapes and positions of the first display area a and the avoiding groove 3 may be determined according to actual design requirements, fig. 3 to 5 are three front views of the display module provided in the embodiment of the present application, and fig. 6 and 7 are partial structural views of two display panels provided in the embodiment of the present application.
In the same display panel, the first display area a and the avoiding groove 3 are similar in shape and correspond in position. The first display area a shown in fig. 3 is U-shaped, and the avoiding groove 3 corresponding to the first display area a may be a U-shaped groove shown in fig. 6; the first display area a shown in fig. 4 is circular, and the avoidance groove 3 corresponding to the first display area a may be a circular groove shown in fig. 7; the first display area a shown in fig. 5 is in a droplet shape, and the avoidance groove 3 corresponding to the first display area a may be a droplet-shaped groove. Of course, the first display area a and the avoiding groove 3 may have other shapes, and will not be described herein.
In the display panel provided by the embodiment of the application, the first sensor group may include a first camera group and a light intensity sensor, and the first camera group includes at least one camera. The first sensor group may further include a home key, an infrared distance sensor, and the like.
Since the organic light emitting sub-pixel 1 of the first display area a has the transparent region 122 therein, when the first sensor group is disposed in the avoiding groove 3, ambient light can be sensed through the transparent region 122, or light waves can be emitted to the environment through the transparent region 122, so that the first sensor group can operate normally. Because the organic light emitting sub-pixel 1 of the first display area a further has the light emitting area 121, the first display area a also has a display function, and thus the first area and the second area of the display module 200 can form a complete display area, so that the display device has a better overall screen display effect, and the screen duty ratio of the display device is improved.
In addition, in display device, only need set up the groove 3 of dodging that holds first sensor group in backlight unit 100, need not to slot on the display module assembly 200, this has reduced display module assembly 200's technology degree of difficulty and cost, helps improving display module assembly 200's mechanical strength to guarantee that display module assembly 200 has higher quality.
In an embodiment of the present application, as shown in fig. 1, the projection range of the first display area a in the backlight module 100 completely covers the avoiding groove 3 and at least partially exceeds the avoiding groove 3. That is, the organic light emitting sub-pixel 1 at the edge position in the first display area a is outside the edge of the avoidance groove 3.
Taking fig. 1 as an example, each organic light-emitting sub-pixel 1 in the block a1 of fig. 1 faces the avoiding groove 3, and each organic light-emitting sub-pixel 1 in the block a2 of fig. is outside the edge of the avoiding groove 3. Optionally, at any edge position of the first display area a, at least 1 pixel (i.e., 3 organic light emitting sub-pixels 1 of different light emitting colors) is outside the edge of the avoiding groove 3.
In an embodiment of the present application, as shown in fig. 1, the display panel further includes a first light shielding layer 4, and the first light shielding layer 4 is disposed between the backlight module 100 and the display module 200. The first light shielding layer 4 surrounds the evasion groove 3 and is opposite to the portion of the first display area a beyond the evasion groove 3. The first light shielding layer 4 can block light emitted from a portion of the backlight module 100, so as to prevent the portion of the light from affecting a portion of the first display area a beyond the avoiding groove 3.
Taking fig. 1 as an example, each organic light-emitting sub-pixel 1 in the block a2 in fig. 1 is outside the edge of the avoiding groove 3, and the first light-shielding layer 4 is opposite to the region defined by the block a2, so as to prevent each organic light-emitting sub-pixel 1 in the block a2 from being irradiated by the light emitted by the backlight module 100, and eliminate the influence of the light emitted by the backlight module 100 on each organic light-emitting sub-pixel 1 in the block a 2.
In one embodiment of the present application, the display panel includes a first substrate 5 and a second substrate 6 stacked on each other, the first substrate 5 is attached to the backlight module 100, and the second substrate 6 is disposed on a side of the first substrate 5 away from the backlight module 100.

A plurality of liquid crystal sub-pixels 2 are disposed in portions of the first substrate 5 and the second substrate 6 in the second display region B.
Taking fig. 1 as an example, a portion of the first substrate 5 and the second substrate 6 in a box a belongs to the first display area a, and the sub-pixels in the box a are both the organic light emitting sub-pixels 1. Optionally, the portion of the first substrate 5 belonging to the first display area a is completely transparent, and no other film layer is disposed, so as to ensure that enough light in the environment can enter the avoiding groove 3 to be sensed by the first sensor group to a greater extent.

The arrangement mode can enable the light emitting area 121 and the transparent area 122 in the first display area a to be distributed more uniformly, and can ensure that the first display area a has better display effect and light transmission uniformity.
Alternatively, as shown in fig. 9, the first pixel driving circuit 11 includes a switching device T1, a switching device T2, and a capacitor C1. The grid electrode of the switching device T1 is electrically connected with the scanning line, the source electrode of the switching device T1 is electrically connected with the signal line, and the drain electrode of the switching device T1 is electrically connected with the first end of the capacitor C1 and the grid electrode of the switching device T2; a second terminal of the capacitor C1 is electrically connected to a reference voltage terminal (e.g., ground); the source of the switching device T2 is electrically connected to the voltage terminal VDD, the drain of the switching device T2 is electrically connected to the first terminal of the organic light emitting cell 12, and the second terminal of the organic light emitting cell 12 is electrically connected to the voltage terminal VCOM.
The display panel works in a progressive scanning mode, a high level is input into a scanning line port to start the switch device T1, and meanwhile, a data line port inputs corresponding data voltage signals to the switch device T2 and the capacitor C1 synchronously through the switch device T1, so that the current flowing through the switch device T2 is controlled, and the capacitor C1 is charged; when the port of the scan line is switched to a low voltage, the switching device T1 is turned off, and the capacitor C1 provides a gate voltage to the switching device T2, so as to continuously maintain the current flowing through the switching device T2.
It should be noted that fig. 9 shows a relatively typical circuit configuration diagram of the first pixel driving circuit 11. It will be apparent to those skilled in the art that various modifications and adaptations can be made to the first pixel driving circuit 11 without departing from the principles of the invention and are intended to be within the scope of the invention.

Although not explicitly shown in fig. 1, it is understood by those skilled in the art that the portion of the first substrate 5 belonging to the second display region B is provided with the second pixel driving circuit 21 of each liquid crystal sub-pixel 2; the second substrate 6 is provided with a color film 23 of each liquid crystal sub-pixel 2 at a portion belonging to the second display region B, a position indicated by reference numeral 23 in the figure can be regarded as a position where the color film 23 of one liquid crystal sub-pixel 2 is located, and the second pixel driving circuit 21, the liquid crystal cell 22, and the color film 23 are sequentially stacked. Taking fig. 1 as an example, the first substrate 5 and the second substrate 6 belong to the second display area B in a part of a frame B, and the sub-pixels in the frame B are all liquid crystal sub-pixels 2.
Alternatively, as shown in fig. 10, the second pixel driving circuit 21 includes a switching device T3 and a capacitor C2. The gate of the switch device T3 is electrically connected to the scan line, the source of the switch device T3 is electrically connected to the signal line, the drain of the switch device T1 is electrically connected to the first terminal of the capacitor C2 and the first terminal of the liquid crystal cell 22, the second terminal of the capacitor C2 is electrically connected to a reference voltage terminal (e.g., ground), and the second terminal of the liquid crystal cell 22 is electrically connected to the voltage terminal VCOM.
The display panel operates in a progressive scanning mode, where the scanning line port inputs a high level enable switch device T3, and at the same time, the data line synchronously inputs corresponding data voltage signals to the electrodes on the liquid crystal cell 22 and the capacitor C2 to drive the liquid crystal in the liquid crystal cell 22 to deflect and charge the capacitor C. When the scan line port is switched to a low voltage, the switching device T3 turns off and the capacitor C discharges to maintain the deflected state of the liquid crystal in the liquid crystal cell 22.
It should be noted that a relatively typical circuit configuration diagram of the second pixel drive circuit 21 is shown in fig. 10. It will be apparent to those skilled in the art that various modifications and adaptations can be made to the second pixel driving circuit 21 without departing from the principles of the invention and are intended to be included within the scope of the invention.
