Embodiment approach 1
[0053] In this exemplary embodiment, the via hole 3 occupies part of the first area 1, and a sub-pixel area not provided with the via hole 3 adjacent to the sub-pixel area provided with the via hole 3 is provided with a light-emitting display sub-pixel , the light-emitting display sub-pixel may extend to the sub-pixel area provided with the via hole 3 . refer to figure 2 A schematic diagram of an example implementation of the shown display panel with fingerprint recognition function; refer to figure 2 To illustrate the first example embodiment, a via hole 3 is provided in the upper middle sub-pixel area, and a light-emitting display sub-pixel is provided in the lower middle sub-pixel area, and the light-emitting display sub-pixel extends to the side of the via hole 3 and extends to the upper part. An area of the middle sub-pixel area not occupied by the via hole 3 . In the sub-pixel area in the middle of the upper part, no light-emitting display sub-pixels may be provide...
Embodiment approach 2
[0057] The sub-pixel area provided with the via hole 3 may include a first drive circuit, and the projected area of the first drive circuit on the sub-pixel area provided with the via hole 3 is the first area, that is, the first drive circuit is on the backplane or The projected area of the lower surface is the first area. The sub-pixel area not provided with the via hole 3 includes a second driving circuit, and the projected area on the sub-pixel area not provided with the via hole 3 is the second area, that is, the projection of the second driving circuit on the upper or lower surface of the backplane The area is the second area. The first area may be smaller than the second area. Specifically, the number of thin film transistors and the number of capacitors used by the first driving circuit are respectively smaller than the number of thin film transistors and the number of capacitors used by the second driving circuit. By reducing the number of thin film transistors a...
Embodiment approach 3
[0060] refer to Figure 4 A schematic diagram of yet another exemplary embodiment of a display panel with a fingerprint recognition function shown, in this exemplary embodiment, the sub-pixel area where the via hole 3 is provided does not include the light-emitting display sub-pixel, that is, the sub-pixel area where the via hole 3 is provided No light-emitting display sub-pixels are provided. This situation is generally used when the area of the via hole 3 that needs to be set is too large. The via hole 3 can occupy the entire area of the sub-pixel, or most of the area. Even if there is a part of the area left, it is not enough to set up the light-emitting display sub-pixel, driving circuit, etc. Wait.
[0061] The metal light-shielding layer 6 is disposed between the base substrate 5 and the photo-sensing unit 11 , and a light-transmitting hole 61 corresponding to the via hole 3 and the photo-sensing unit is disposed thereon. In this exemplary embodiment, the light tra...
