Example Embodiment
[0074] Example 1
[0075] In this embodiment, the above-mentioned fingerprint identification device is disposed in the above-mentioned display area 40 .
[0076] For example, it can be Image 6 Set within each subpixel 01 shown a figure 2 The fingerprint recognition unit 02 is shown. Specifically, as Figure 7 As shown, the first transistor T1 and the photosensitive device 20 in the fingerprint identification unit 02 are arranged in one sub-pixel 01 .
[0077] In this way, the area 40 can be redisplayed to realize fingerprint recognition.
[0078] In addition, since the second gate line G2 and the data line D can intersect to define the sub-pixel 01 , the first gate line G1 and the read signal line RL can define the fingerprint identification unit 02 . Therefore, in order to make the wiring structure on the entire array substrate neat, preferably, the first gate line G1 can be parallel to the second gate line G2, and the read signal line RL can be parallel to the data li...
Example Embodiment
[0079] Embodiment 2
[0080] In this embodiment, the above-mentioned fingerprint identification device is also disposed in the display area 40 . Different from the first embodiment, in this embodiment, not every sub-pixel 01 is provided with the above-mentioned fingerprint identification unit 02 .
[0081] Specifically, the above-mentioned fingerprint identification unit 02 may be arranged in a sub-pixel of the pixel unit. For example, when the sub-pixels constituting the pixel unit include first-color sub-pixels 110, second-color sub-pixels 111, and third-color sub-pixels 112, the fingerprint recognition unit 02 can be arranged in the first-color sub-pixels 110, the second-color sub-pixels 110, and the second-color sub-pixels 110. in the sub-pixel 111 or the third-color sub-pixel 112 . Wherein, the above-mentioned first color, second color and third color constitute three primary colors.
[0082] Alternatively, when the display area 40 includes pixel units such as Figure ...
