These terms are only used to distinguish the display region, the hollow region, the gate line, the data line, the emission control line, the gate driving unit, and the emission control unit from each other. For example, the first display region, the hollow region, the gate line, the data line, the light emission control line, the gate driving unit, and the light emission control unit may also be referred to as a second display region, the hollow region, the gate line, the data line, the light emission control line, the gate driving unit, and the light emission control unit, and similarly, the second display region, the hollow region, the gate line, the data line, the light emission control line, the gate driving unit, and the light emission control unit may also be referred to as a first display region, the hollow region, the gate line, the data line, the light emission control line, the gate driving unit, and the light emission control unit, without departing from the scope of the embodiments of the present invention.
An embodiment of the present invention provides an organic light emitting display panel 100, as shown in fig. 1, including a first hollow area 31, a second hollow area 32, and a display area 20. The first and second hollow areas 31 and 32 are arranged in the first direction X, and the display area 20 is disposed around the first and second hollow areas 31 and 32.
With reference to fig. 1, the organic light emitting display panel 100 further includes a plurality of pixel units P, a plurality of gate lines G, a plurality of data lines D insulated from and crossing the gate lines G, a plurality of light emitting control lines E, a first gate driving unit S1, a second gate driving unit S2, a third gate driving unit S3, a first light emitting control unit F1, a second light emitting control unit F2, and a third light emitting control unit F3. The pixel unit P is located in the display area 20, and the first and second hollow areas 31 and 32 are not provided with the pixel unit P. That is, the first and second hollow regions 31 and 32 are not displayed, and since the pixel unit P is not disposed in the first and second hollow regions 31 and 32, the first and second hollow regions 31 and 32 may transmit light bilaterally. That is, light of one side of the organic light emitting display panel 100 may be projected to the other side through the first and second hollow areas 31 and 32. The light transmittance of the first and second hollow regions 31 and 32 is much greater than that of the display region 20. The first and second hollow areas 31 and 32 may not be provided with any pixel circuits, organic light emitting devices, or even any hierarchy.
With continued reference to fig. 1, the first hollow area 31, the second gate driving unit S2, the second light-emitting control unit F2 and the second hollow area 32 are arranged along the first direction X. That is, in the first direction X, the first hollow region 31, the second gate driving unit S2, the second light emission control unit F2, and the second hollow region 32 are sequentially arranged in this order. The second gate driving unit S2 is disposed adjacent to a first side of the first hollow area 31. That is, the second gate driving unit S2 is disposed at one side of the display region 20 between the first hollow region 31 and the second hollow region 32, and the second light emission controlling unit F2 is disposed at the other side. That is, the scan signal of the pixel unit P of the display region 20 located between the first hollow region 31 and the second hollow region 32 is provided by the one-side gate driving unit only, that is, the gate driving of the pixel unit P of the display region 20 located between the first hollow region 31 and the second hollow region 32 adopts the one-side driving.
With continued reference to fig. 1, the second light-emission control unit F2 is disposed adjacent to the first side of the second hollow region 32. That is, the light emission control signal of the pixel unit P of the display area 20 located between the first hollow area 31 and the second hollow area 32 is provided by only one side light emission control unit, that is, the light emission control of the pixel unit P of the display area 20 between the first hollow area 31 and the second hollow area 32 employs one-sided driving.
The organic light emitting display panel 100 according to the embodiment of the invention may effectively use the region between the first hollow region 31 and the second hollow region 32 for display because the second gate driving unit S2 and the second light emission control unit F2 are disposed between the first hollow region 31 and the second hollow region 32. In addition, the organic light emitting display panel 100 provided in the embodiment of the present invention is provided with the second gate driving unit S2 and the second light emitting control unit F2 to drive the pixel unit P between the first hollow area 31 and the second hollow area 32, so that the gate line G and the light emitting control line E are prevented from being connected to each other in a winding manner in the first hollow area 31 and the second hollow area 32, and the area of the non-display area around the first hollow area 31 and the second hollow area 32 is reduced, which not only makes the organic light emitting display panel 100 more beautiful, but also further improves the screen occupation ratio of the organic light emitting display panel 100, and gives consideration to the visual experience and the functional requirements of the user on the organic light emitting display panel.

The first side 321 of the second hollow region 32 is disposed opposite to the second side 322 of the second hollow region 32. That is, the first side 321 of the second hollow region 32 is not adjacent to the second side 322 of the second hollow region 32. That is, the opposite side of the first side 321 of the second hollow area 32 is the second side 322 of the second hollow area 32.

The first side 321 of the second hollow area 32 is adjacent to the second light-emission control unit F2.
The pixel cells P of the first display region 201 are provided with the scan signal only by the first gate driving unit S1 located at one side, i.e. the gate driving of the pixel cells P of the first display region 201 adopts single-side driving. The pixel cells P of the third display region 203 are provided with the scan signal only by the third gate driving unit S3 located at one side, i.e. the gate driving of the pixel cells P of the third display region 203 adopts single-side driving.
Further, with continued reference to fig. 2, the first gate driving unit S1 is located between the first light-emitting control unit F1 and the first display area 201. That is, the first light-emitting control unit F1 is farther from the display area 20 than the first gate driving unit S1, that is, the first light-emitting control unit F1 is disposed on the side of the first gate driving unit S1 away from the display area 20. The third gate driving unit S3 is positioned between the third light emission control unit F3 and the third display region 203.

Further, with reference to fig. 2, the number of the first gate driving units S1 is greater than that of the first light-emitting control units F1, and the number of the third gate driving units S3 is greater than that of the third light-emitting control units F3. In fig. 2, one first light emission control unit F1 corresponds to two first gate driving units S1, one second light emission control unit F2 corresponds to two second gate driving units S2, and one third light emission control unit F3 corresponds to two third gate driving units S3. In conjunction with fig. 1 and 2, one gate driving unit may correspond to one row of pixel units P, that is, one emission control unit may be disposed corresponding to two rows of pixel units P. It should be noted that fig. 2 only shows one corresponding manner of the light emission control units and the gate driving units, and the ratio of the number of the light emission control units to the number of the corresponding gate driving units may be 1:4 or 1:8 in other embodiments of the present invention. That is, one first light emission control unit F1 corresponds to four or eight first gate driving units S1, one second light emission control unit F2 corresponds to four or eight second gate driving units S2, and one third light emission control unit F3 corresponds to four or eight third gate driving units S3.
