Around the second sub-pixel region 2, there are disposed a plurality of first sub-pixel regions 1 adjacent thereto. Colors of the light-emitting display sub-pixels in the first sub-pixel region 1 are, for example, red, green and blue. Since the human eye is sensitive to green, the second sub-pixel region 2 may be selected to provide the green light-emitting display sub-pixel, which is advantageous for avoiding the influence on the display effect. Of course, in other embodiments, the color of the light-emitting display sub-pixels disposed in the second sub-pixel region 2 is not limited to green, and red or blue light-emitting display sub-pixels may also be used.

In the embodiment shown in FIG. 5, in the second sub-pixel region 2 provided with the through hole 111 and the light detecting unit 4, the second light-emitting unit 8 is added to compensate for light and solve the problem of light-emitting unevenness caused by the second sub-pixel region 2 lacking the light-emitting unit; At the same time, projections of the second light-emitting unit 8 and the through-hole 111 on the substrate 2 do not overlap, so as to avoid interference on the light-to-light detection unit 4 caused by light emitted by the second light-emitting unit 8. Therefore, the fingerprint identification display panel of this embodiment improves both fingerprint identification accuracy and display effect of the display panel.
