Specifically, the substrate 11 is used to support other constituent elements disposed on the substrate 11. The substrate 11 may be a transparent hard substrate (e.g., a transparent glass substrate) or a transparent flexible substrate (e.g., a transparent plastic substrate), and the shape of the substrate 11 may be a plane, a curved surface, or other irregular shape. It should be understood that the material and shape of the substrate 11 are not limited thereto.
In this embodiment, the substrate 11 is provided with a blind hole 12, and the blind hole 12 is circular. In other embodiments, two, three or more blind holes 12 may be disposed on the substrate 11, and the blind holes 12 may also take other shapes, such as an oval shape, a figure 8 shape, etc.
It should be noted that the number, shape and position of the blind holes 12 are not limited herein, and those skilled in the art can set the number, shape and position of the blind holes 12 according to actual requirements.
A plurality of scanning lines (not shown), a plurality of data lines (not shown), and a pixel array (not shown) defined by the plurality of scanning lines and the plurality of data lines crossing each other are formed on the substrate 11, and the pixel array includes a plurality of first pixel units, each of the first pixel units is provided with a polysilicon thin film transistor, and each of the polysilicon thin film transistors is connected to a corresponding scanning line and a corresponding data line.
The plurality of first pixel units are arranged in an array. Correspondingly, the polysilicon thin film transistors in the first pixel units are also arranged in an array. The polysilicon thin film transistor includes a gate electrode, a source electrode, a drain electrode, and a low temperature polysilicon layer, the gate electrode, the source electrode, and the drain electrode are insulated from each other, the low temperature polysilicon layer serves as a semiconductor active layer, and the source electrode and the drain electrode are connected to the low temperature polysilicon layer, respectively (not shown in the figure).
As shown in fig. 2, the substrate 11 includes a blind hole region and a first display region surrounding the blind hole region, the blind hole 12 is disposed on the blind hole region, the pixel array is disposed on the first display region, the pixel array includes a plurality of first pixel units disposed in an array, each first pixel unit is provided with at least two polysilicon thin film transistors, each polysilicon thin film transistor includes a gate, a source, a drain, and a low temperature polysilicon layer, each first pixel unit includes at least two low temperature polysilicon layers of the polysilicon thin film transistors, and for simplicity, the low temperature polysilicon layer 13 of each first pixel unit is represented by only one rectangular pattern in the drawing. Accordingly, the first pixel units have a plurality of low-temperature polysilicon layers 13, that is, the low-temperature polysilicon layers 13 are arranged in one-to-one correspondence with the pixel units of the pixel array.
Referring to fig. 2, the low-temperature polysilicon layers 13 are disposed at intervals, and the low-temperature polysilicon layers 13 are not connected to each other between any two adjacent first pixel units, and keep a certain distance. Preferably, the low-temperature polysilicon layers 13 are made of the same material in the same layer, that is, the low-temperature polysilicon layers 13 of the first pixel units are made of the same material and formed by the same composition process.
The array substrate 10 further includes an organic light emitting diode OLED and a storage capacitor (not shown in the figure) formed on the substrate 11, and the storage capacitor and the polysilicon thin film transistor constitute a pixel circuit to drive the organic light emitting diode OLED to emit light.
In the prior art, the low-temperature polysilicon layers 13 are usually connected in staggered rows or connected up and down. Therefore, although the initialization of the anode and the capacitor end of the OLED can be simultaneously realized by the same signal, the layout space of the signal line is saved. However, since the initialization signals of the anode and the capacitor of the OLED are not independently controlled, smear-like display unevenness is likely to occur at the blind hole position.
In this embodiment, the low-temperature polysilicon layers 13 are designed separately, so that the low-temperature polysilicon layers 13 of adjacent pixel units are not connected to each other. Therefore, as long as one initialization signal line is added to each row of pixel units, the initialization of the anode and the capacitor end of the OLED can be respectively completed by two signals, the degree of freedom of signal control can be increased, the adverse effect caused by the difference of graphic design between the blind hole area and the first display area can be avoided, and the smear-shaped uneven display of the blind hole position can be effectively improved in the manufacturing process.
Accordingly, the present invention also provides an organic light emitting display panel including the array substrate 10 as described above. Please refer to the above, which is not described herein.
Accordingly, the present invention also provides an organic light emitting display device including: a camera (not shown in the drawings) and the organic light emitting display panel as described above; the camera is arranged in the blind hole 12 of the organic light-emitting display panel; or the camera is arranged below the organic light emitting display panel and corresponds to the blind hole 12.

For this reason, it is necessary to perform brightness compensation through a driving chip, that is, the driving chip of the organic light emitting display device has a brightness compensation function. The driving chip is configured to detect and compare the brightness of the first display area and the second display area, and adjust the data voltage of the first display area or the second display area according to the comparison result, so that the brightness of the first display area and the second display area is kept uniform.
